Description

无电净水***Electrical-free water purification system

技术领域Technical field

本发明涉及水净化技术领域，尤其涉及一种的无电净水***。The present invention relates to the technical field of water purification, and in particular to an electricityless water purification system.

背景技术Background technique

在净水***中，需要利用开关阀关闭相关管路以用于将净水***关闭以阻止其制水，在有电净水***中，可采用电磁阀关闭相关管路以阻止净水***制水。然而，在无电净水***中，电磁阀并不推荐使用。因而，申请人在先申请的专利，专利公布号为CN108793471的中国专利公开了一种依靠自来水压力实现无电自动循环控制的净水方法，在该净水方法中，提供了一种四面阀，滤膜件（或称过滤装置）的净水端（或称净水出口）连通四面阀的C、D端（控制端），滤膜件的浓水端（浓水出口）连通四面阀的A、B端（被控制端），在水箱内阀门关闭后，四面阀的C、D端的压力升高，从而使得四面阀的活塞移动以实现对浓水端的截断，进而关闭浓水的排放口，从而关闭净水***，进而阻止净水***制水。In the water purification system, it is necessary to use the on-off valve to close the relevant pipelines to shut down the water purification system to prevent it from producing water. In the electric water purification system, the solenoid valve can be used to close the relevant pipelines to prevent the water purification system from producing water. water. However, the use of solenoid valves is not recommended in non-electrical water purification systems. Therefore, the patent previously applied for by the applicant, the Chinese patent with patent publication number CN108793471, discloses a water purification method that relies on tap water pressure to achieve automatic circulation control without electricity. In this water purification method, a four-sided valve is provided. The clean water end (or purified water outlet) of the membrane filter (or filter device) is connected to the C and D ends (control end) of the four-sided valve, and the concentrated water end (concentrated water outlet) of the membrane filter is connected to A of the four-sided valve. , B end (controlled end), after the valve in the water tank is closed, the pressure at the C and D ends of the four-sided valve increases, causing the piston of the four-sided valve to move to cut off the concentrated water end, and then close the discharge port of the concentrated water. This shuts down the water purification system, thereby preventing the water purification system from producing water.

然而，上述专利在阻止净水***制水方面却存在如下缺陷：However, the above-mentioned patent has the following flaws in preventing the water purification system from producing water:

虽然将滤膜件的浓水端关闭能够阻止净水***制水，然而，原水出水端（或称自来水管路）与滤膜件的原水端（或称原水进口）仍保持连通状态，进而造成在停止制水期间，滤膜件中的滤膜始终承受来自原水出水端的压力，这对滤膜件的后续的使用效果和使用寿命不利，尤其是来自原水出水端的压力波动还会直接影响到滤膜件。另外，滤膜件中长期存有水，进而容易对滤膜件内造成污染，且，重新制水后，起始阶段流出的的水的水质会很差。Although closing the concentrated water end of the membrane filter can prevent the water purification system from producing water, the raw water outlet end (or tap water pipeline) and the raw water end of the membrane filter (or raw water inlet) are still connected, causing During the period of stopping water production, the filter membrane in the membrane filter element is always under pressure from the raw water outlet, which is detrimental to the subsequent use and service life of the filter membrane element. In particular, the pressure fluctuation from the raw water outlet end will also directly affect the filter. Membrane parts. In addition, water has been stored in the membrane filter for a long time, which can easily cause contamination in the membrane filter. Moreover, after water is produced again, the quality of the water flowing out in the initial stage will be very poor.

在净水***正常制水过程中，浓水侧201的浓水从浓水出口2012通过浓水出水管路603进入到浓水排放阀400中，该浓水排放阀400具有一个能够限制浓水流出的第一排放口，该第一排放口可以为设置成较小通流截面的出水口，也可以为可进行调节通流截面的出水口，以用于在制水过程中限制浓水的排放量并使第一过滤装置200中建立压力以进行正常制水。进入到浓水排放阀400的浓水可通过第一排放口流出而最终从浓水排放端C排走。During the normal water production process of the water purification system, the concentrated water on the concentrated water side 201 enters the concentrated water discharge valve 400 from the concentrated water outlet 2012 through the concentrated water outlet pipe 603. The concentrated water discharge valve 400 has a valve capable of limiting the concentrated water. The first discharge port that flows out can be a water outlet with a smaller flow cross section, or a water outlet with an adjustable flow cross section, so as to limit the flow of concentrated water during the water production process. The discharge volume is increased and pressure is established in the first filtering device 200 for normal water production. The concentrated water entering the concentrated water discharge valve 400 can flow out through the first discharge port and finally be discharged from the concentrated water discharge end C.

取水端B可以为取水龙头501以供用户即取即用，也可以为取水箱502以用于存放一定量的净化水，还可以为取水龙头501与取水箱502的并联组合。The water end B can be a faucet 501 for immediate use by the user, a water tank 502 for storing a certain amount of purified water, or a parallel combination of the faucet 501 and the water tank 502 .

保压部件设置在净水出水管路602中，该保压部件用于在取水端关闭时，保压部件限制保压部件上游的净水出水管路602中的净化水朝第一过滤装置200方向反流，并使得保压部件的上游的净水出水管路602保压。The pressure-maintaining component is provided in the purified water outlet pipeline 602. The pressure-maintaining component is used to restrict the purified water in the purified water outlet pipeline 602 upstream of the pressure-maintaining component from flowing towards the first filtering device 200 when the water intake end is closed. The direction of the flow is reversed, and the clean water outlet pipe 602 upstream of the pressure maintaining component maintains pressure.

第一液控阀100设置在自来水管路601上，即，该第一液控阀100的进水口与靠近原水出水端A的一侧的自来水管路601连接，出水口与远离原水出水端A的一侧的自来水管路601连接。The first hydraulic control valve 100 is disposed on the tap water pipeline 601, that is, the water inlet of the first hydraulic control valve 100 is connected to the tap water pipeline 601 on the side close to the raw water outlet A, and the water outlet is connected to the tap water outlet A away from the raw water outlet. The tap water pipe 601 on one side is connected.

该第一液控阀100具有液控口101，自取水端B与保压部件之间的净水出水管路602上引出第一液控管路102而连接至第一液控阀100的液控口101，该第一液控阀100中的阀芯部件（机构）基于液控口101处来自净水出水管路602的净化水的压力而控制第一液控阀100的通断，即，当取水端B处于打开的状态时，净水出水管路602中的净化水的压力较低，该净水压力不足驱动第一液控阀100的阀芯部件（机构），进而该第一液控阀100处于打开状态，自来水管路601处于导通状态，第一过滤装置200处于制水状态，而在取水端B关闭后，保压部件关闭，此时，保压部件与取水端B之间的净水出水管路602中的净化水的压力驱动第一液控阀100中的阀芯部件（机构）而使第一液控阀100关闭，进而将自来水管路601关闭，进而阻止净水***制水。The first hydraulic control valve 100 has a liquid control port 101, and a first hydraulic control pipeline 102 is led from the clean water outlet pipeline 602 between the water intake end B and the pressure maintaining component and is connected to the first hydraulic control valve 100. Liquid control port 101, the valve core component (mechanism) in the first liquid control valve 100 controls the on/off of the first liquid control valve 100 based on the pressure of purified water from the purified water outlet pipeline 602 at the liquid control port 101, That is, when the water intake port B is in an open state, the pressure of the purified water in the purified water outlet pipe 602 is low, and the purified water pressure is insufficient to drive the valve core component (mechanism) of the first hydraulic control valve 100, and then the third A hydraulic control valve 100 is in an open state, the tap water pipeline 601 is in a conductive state, the first filtering device 200 is in a water production state, and after the water intake end B is closed, the pressure maintaining component is closed. At this time, the pressure maintaining component and the water intake end The pressure of the purified water in the purified water outlet pipeline 602 between B drives the valve core component (mechanism) in the first hydraulic control valve 100 to close the first hydraulic control valve 100, thereby closing the tap water pipeline 601, and then Prevent the water purification system from producing water.

本发明所提供的上述的无电净水***的优势在于：The advantages of the above-mentioned electricityless water purification system provided by the present invention are:

1、利用第一液控阀100直接关闭自来水管路601以阻止净水***制水，这使得第一过滤装置200在停止制水后不必承受来自原水出水端A的压力，更不会受到来自原水出水端A的压力波动的影响。1. Use the first hydraulic control valve 100 to directly close the tap water pipeline 601 to prevent the water purification system from producing water. This means that the first filtering device 200 does not have to bear the pressure from the raw water outlet A after stopping the water production, let alone from the The influence of pressure fluctuations at the raw water outlet A.

2、将净水出水管路602中的净化水的压力引入第一液控阀100的液控口101以控制第一液控阀100的通断，进而使得取水端B的工作状态与自来水管路601的通断状态实现关联，进而使得净水***符合制水时使自来水管路601打开，停止制水时使自来水管路601关闭的工作要求。2. Introduce the pressure of the purified water in the purified water outlet pipe 602 into the liquid control port 101 of the first liquid control valve 100 to control the on/off of the first liquid control valve 100, thereby making the working status of the water intake end B consistent with the water pipe The on-off status of the pipeline 601 is correlated, so that the water purification system meets the working requirements of opening the tap water pipeline 601 when water is produced and closing the tap water pipeline 601 when stopping water production.

取水端B若为取水箱502，可选用申请人在先申请的专利公告号为CN211688310U中国专利所公开的净水水箱组合作为取水箱502，该净水水箱组合具有在取水时，其进水口关闭的特点，这使得在利用取水箱502取水时，取水端B与保压部件之间也维持一定压力。If the water intake end B is the water intake tank 502, the water purification water tank combination disclosed by the Chinese patent No. CN211688310U previously applied by the applicant can be used as the water intake tank 502. This water purification water tank combination has the function of closing the water inlet when fetching water. This feature allows a certain pressure to be maintained between the water intake end B and the pressure-maintaining component when using the water intake tank 502 to draw water.

保压部件可以为单向阀300，也可以为清洗箱800，该清洗箱800具有连入净水出水管路602的进水口和出水口以及通气口，通气口能够进行可控的开闭，出水口处具有反向截止的阀结构。The pressure maintaining component can be a one-way valve 300 or a cleaning box 800. The cleaning box 800 has a water inlet and outlet connected to the clean water outlet pipeline 602 and a vent. The vent can be controllably opened and closed. The water outlet has a reverse stop valve structure.

如图3和图4所示，若选用清洗箱800作为保压部件，使清洗箱800设置在高于第一过滤装置200的位置，在关闭取水端B后，清洗箱800内部的反向截止的阀结构将出水口关闭，这使得净化水通过第一液控管路102将第一液控阀100关闭，从而将自来水管路601关闭。As shown in Figures 3 and 4, if the cleaning box 800 is selected as the pressure maintaining component and the cleaning box 800 is set at a position higher than the first filtering device 200, after the water intake end B is closed, the reverse flow inside the cleaning box 800 is cut off. The valve structure closes the water outlet, which allows the purified water to pass through the first liquid control pipeline 102 to close the first liquid control valve 100, thereby closing the tap water pipeline 601.

如图3和图4所示，在自来水管路601关闭后，清洗箱800内部的净化水可基于重力势能通过净水出口2021进入到第一过滤装置200的净水侧202中，利用重力势能以及浓水侧与净水侧之间的渗透压经过滤膜元件中的滤膜实施对滤膜的浸泡清洗，随后从浓水侧201的浓水出口2012流出，并最终从浓水排放端C排走，如此能够实现利用清洗箱800内的净化水对第一过滤装置200的滤膜元件进行浸泡清洗。As shown in Figures 3 and 4, after the tap water pipeline 601 is closed, the purified water inside the cleaning box 800 can enter the purified water side 202 of the first filtering device 200 through the purified water outlet 2021 based on the gravitational potential energy, using the gravitational potential energy. And the osmotic pressure between the concentrated water side and the clean water side performs soaking and cleaning of the filter membrane through the filter membrane in the filter membrane element, and then flows out from the concentrated water outlet 2012 of the concentrated water side 201, and finally flows out from the concentrated water discharge end C Drainage, so that the purified water in the cleaning tank 800 can be used to soak and clean the filter membrane element of the first filter device 200 .

优选地，可通过使清洗箱800内的通气口与阀结构进行关联而使得阀结构关闭时而通气口被打开，如此，当取水端B关闭后，阀结构关闭而通气口自动打开，进而使得停止制水后利用清洗箱800能够自动对第一过滤装置200进行清洗。Preferably, the vent in the cleaning box 800 can be associated with the valve structure so that the vent is opened when the valve structure is closed. In this way, when the water intake end B is closed, the valve structure is closed and the vent is automatically opened, thereby causing the stop After water production, the first filtering device 200 can be automatically cleaned using the cleaning box 800 .

如图3和图4所示，若选用清洗箱800作为保压部件，则优选取水箱502作为取水端B，如此，在清洗箱800对第一过滤装置200进行浸泡清洗过程中，用户依然可以利用取水箱502接水而不会导致清洗箱800与取水箱502之间的净水出水管路602内的净化水卸压。As shown in Figures 3 and 4, if the cleaning box 800 is selected as the pressure maintaining component, the water intake tank 502 is preferably used as the water intake end B. In this way, when the cleaning box 800 is soaking and cleaning the first filter device 200, the user can still Using the water intake tank 502 to receive water will not cause the purified water in the purified water outlet pipeline 602 between the cleaning tank 800 and the water intake tank 502 to be depressurized.

如图3和图4所示，若清洗箱800作为保压部件并用于对第一过滤装置200进行浸泡清洗，优选地，自浓水出水管路603上或从形成于浓水排放阀400并贯通至腔体内的第二排放口引出一旁路605而连接至浓水排放端C；在旁路605上设置有***阀402，***阀402利用来自于第一过滤装置200的浓水侧201的浓水的压力而保持关闭，并在浓水的压力撤销后而打开。该***阀402具体包括阀筒4021、形成于阀筒4021中的阀孔4022、设置于阀筒4021中的阀芯4023以及设置于阀筒4021与阀芯4023上的磁力部件4024，如图10和图11所示，磁力部件4024之间通过磁引力而使得阀芯4023在浓水压力撤销后而复位以将阀孔4022打开。As shown in Figures 3 and 4, if the cleaning box 800 is used as a pressure maintaining component and is used to soak and clean the first filter device 200, it is preferably from the concentrated water outlet pipe 603 or from the concentrated water discharge valve 400 and The second discharge port that penetrates into the cavity leads to a bypass 605 and is connected to the concentrated water discharge end C; a drain valve 402 is provided on the bypass 605, and the drain valve 402 utilizes the pressure from the concentrated water side 201 of the first filter device 200. It remains closed when the concentrate pressure is removed and opens when the concentrate pressure is removed. The drain valve 402 specifically includes a valve cylinder 4021, a valve hole 4022 formed in the valve cylinder 4021, a valve core 4023 provided in the valve cylinder 4021, and a magnetic component 4024 provided on the valve cylinder 4021 and the valve core 4023, as shown in Figure 10 As shown in Figure 11, the magnetic attraction between the magnetic components 4024 causes the valve core 4023 to reset after the concentrated water pressure is removed to open the valve hole 4022.

***阀402在受到大于使得第二液控阀700打开的最低压力时关闭，这使得第一过滤装置200能够维持制水，此时，浓水仅能够通过浓水排放阀400的第一排放口流出而被限制流量而以浓水侧201维持制水压力。The drain valve 402 closes when it is subjected to a pressure greater than the lowest pressure that causes the second hydraulic control valve 700 to open, which enables the first filter device 200 to maintain water production. At this time, the concentrated water can only pass through the first discharge port of the concentrated water drain valve 400 The flow rate is restricted and the water pressure is maintained on the concentrated water side 201.

在自来水管路601关闭后，浓水侧201的压力降低，***阀402打开，清洗箱800中的净化水经过第一过滤装置200后在从***阀402流出而流向浓水排放端C，这有利于在浸泡清洗阶段浓水侧201的浓水能够被及时的排出，提高了浸泡清洗效率和效果。After the tap water pipeline 601 is closed, the pressure on the concentrated water side 201 decreases, the drain valve 402 opens, and the purified water in the cleaning tank 800 passes through the first filtering device 200 and then flows out of the drain valve 402 to the concentrated water discharge end C. This It is conducive to the concentrated water on the concentrated water side 201 being discharged in time during the soaking and cleaning stage, which improves the efficiency and effect of soaking and cleaning.

本发明的实施方式Embodiments of the invention

在一些优选实施例中，如图2所示，在第一液控阀100的上游设置第二液控阀700，该第二液控阀700具有液控口701，自第二液控阀700上游的自来水管路601上引出第二液控管路702而连接至第二液控阀700的液控口701。当原水的压力低于预设压力时第二液控阀700关闭；当自来水管路601中的原水的压力高于预设压力时，原水通过第二液控管路702而在第二液控阀700的液控口701处驱动第二液控阀700而使第二液控阀700打开。若将预设压力基于第一过滤装置200正常制水的压力进行设定，这使得自来水管路601内的原水低于预设压力时而被第二液控阀700关闭，以避免第一过滤装置200在低压力环境下制水，而在大于预设压力时将自来水管路601打开，该压力能够保证第一过滤装置200正常制水。In some preferred embodiments, as shown in Figure 2, a second hydraulic control valve 700 is provided upstream of the first hydraulic control valve 100. The second hydraulic control valve 700 has a liquid control port 701. From the second hydraulic control valve 700 A second hydraulic control pipeline 702 is led from the upstream tap water pipeline 601 and is connected to the liquid control port 701 of the second hydraulic control valve 700 . When the pressure of the raw water is lower than the preset pressure, the second hydraulic control valve 700 is closed; when the pressure of the raw water in the tap water pipeline 601 is higher than the preset pressure, the raw water passes through the second hydraulic control pipeline 702 and is in the second hydraulic control valve. The hydraulic control port 701 of the valve 700 drives the second hydraulic control valve 700 to open the second hydraulic control valve 700. If the preset pressure is set based on the normal water production pressure of the first filtering device 200, this will cause the raw water in the tap water pipeline 601 to be closed by the second hydraulic control valve 700 when it is lower than the preset pressure to avoid the first filtering device. 200 produces water in a low-pressure environment, and opens the tap water pipeline 601 when the pressure is greater than the preset pressure. This pressure can ensure that the first filtering device 200 can produce water normally.

在一些优选实施例中，如图4所示，第一液控阀100与第二液控阀700之间的自来水管路601上设置有第二过滤装置900。第二过滤装置900与原水出水端A之间还设置有第三液控阀901，第三液控阀901与第二液控阀700并联，第三液控阀901具有液控口9011，自第三液控阀901的下游的自来水管路601上引出第三液控管路9012而连接至第三液控阀901的液控口9011；自第一液控阀100与第二过滤装置900之间的自来水管路601上引出取水端D，自第二过滤装置900的浓水出口引出清洗端E；在取水端D以及清洗端E关闭后，自来水管路601中的原水通过第三液控管路9012而借由第三液控阀901的液控口9011驱动第三液控阀901关闭，并在取水端D或清洗端E打开后，原水撤销对第三液控阀901的驱动而第三液控阀901打开。第三液控阀901与第一液控阀100具有一致的受控与通断状态的关系。In some preferred embodiments, as shown in FIG. 4 , a second filtering device 900 is provided on the tap water pipeline 601 between the first hydraulic control valve 100 and the second hydraulic control valve 700 . A third liquid control valve 901 is also provided between the second filtering device 900 and the raw water outlet A. The third liquid control valve 901 is connected in parallel with the second liquid control valve 700. The third liquid control valve 901 has a liquid control port 9011. The third liquid control pipe 9012 is led from the tap water pipeline 601 downstream of the third liquid control valve 901 and is connected to the liquid control port 9011 of the third liquid control valve 901; from the first liquid control valve 100 and the second filtering device 900 The water intake end D is led from the tap water pipeline 601 between them, and the cleaning end E is led from the concentrated water outlet of the second filtering device 900; after the water intake end D and the cleaning end E are closed, the raw water in the tap water pipeline 601 passes through the third liquid The control pipeline 9012 drives the third hydraulic control valve 901 to close through the hydraulic control port 9011 of the third hydraulic control valve 901, and after the water intake end D or the cleaning end E is opened, the raw water cancels the drive of the third hydraulic control valve 901 And the third hydraulic control valve 901 is opened. The third hydraulic control valve 901 and the first hydraulic control valve 100 have a consistent relationship between controlled and on-off states.

当来自原水出水端A的原水的压力低于为第二液控阀700所设置的预设压力，且取水端D、清洗端E均关闭时，自来水管路601中的原水的压力不足而导致第二过滤装置900不能正常制水，此时，第二液控阀700关闭，此时，第三液控阀901的液控口9011的液体驱动第三液控阀901而将第三液控阀901关闭，进而使得自来水管路601关闭以避免第二过滤装置900在低压环境下制水。When the pressure of the raw water from the raw water outlet A is lower than the preset pressure set for the second hydraulic control valve 700, and the water intake end D and the cleaning end E are both closed, the pressure of the raw water in the tap water pipeline 601 is insufficient and causes The second filter device 900 cannot control water normally. At this time, the second liquid control valve 700 is closed. At this time, the liquid in the liquid control port 9011 of the third liquid control valve 901 drives the third liquid control valve 901 and controls the third liquid control valve 901 . The valve 901 is closed, thereby closing the tap water pipeline 601 to prevent the second filtering device 900 from producing water in a low-pressure environment.

而在取水端D或清洗端E打开后，原水撤销对第三液控阀901的驱动而第三液控阀901打开，进而使得自来水管路601打开，如此，来自原水出水端A的原水进入到第二过滤装置900中。After the water intake end D or the cleaning end E is opened, the raw water cancels the drive of the third hydraulic control valve 901 and the third hydraulic control valve 901 opens, thereby causing the tap water pipeline 601 to open. In this way, the raw water from the raw water outlet A enters. to the second filtering device 900.

如此，通过打开取水端D可使得原水经过第二过滤装置900进行过滤，从取水端D流出的初步净化的净化水用于除直饮外的其他用途，如洗菜、洗碗等。通过打开清洗端E可使得原水冲洗第二过滤装置900的浓水侧，进而实现对第二过滤装置900的清洗。In this way, by opening the water intake end D, the raw water can be filtered through the second filtering device 900, and the initially purified purified water flowing out from the water intake end D can be used for other purposes besides direct drinking, such as washing vegetables, washing dishes, etc. By opening the cleaning end E, the raw water can flush the concentrated water side of the second filtering device 900, thereby cleaning the second filtering device 900.

2、自来水管路601内的原水低于预设压力时而被第二液控阀700关闭，以避免第一过滤装置200在低压力环境下制水，而在大于预设压力时将自来水管路601打开，该压力能够保证第一过滤装置200正常制水。2. When the raw water in the tap water pipeline 601 is lower than the preset pressure, it is closed by the second hydraulic control valve 700 to prevent the first filtering device 200 from producing water in a low pressure environment. 601 is opened, and this pressure can ensure that the first filtering device 200 can produce water normally.

Block the valve hole 17, and, as shown in Figure 5, after the downward pressure on the first diaphragm 20 is removed, the water entering the outer ring cavity 18 from the water inlet 13 can push the first diaphragm 20 close to it. The deformation of the edge area or the deformation of the entire area pushes up to open the valve hole 17 . An eardrum with certain elasticity and flexibility can be selected as the first diaphragm 20 .

第一膜片20与外环腔18对应的区域设置有平衡孔21，优选地，使平衡孔21设置在靠近进水口13的内端区域；第一膜片20与阀孔17对应的区域设置有受控孔22，该受控孔22由穿设第一膜片20并向上凸出于第一膜片20的管体23的顶部形成。The first diaphragm 20 is provided with a balance hole 21 in an area corresponding to the outer annular cavity 18. Preferably, the balance hole 21 is provided in an inner end area close to the water inlet 13; the first diaphragm 20 is provided in an area corresponding to the valve hole 17. There is a controlled hole 22 formed by the top of the tube body 23 that penetrates the first diaphragm 20 and protrudes upward from the first diaphragm 20 .

上阀体12的顶部具有液控口15，该液控口15作为第一液控阀100的液控口101或者作为第三液控阀901的液控口9011，该液控口15可由安装于上阀体12的顶部的接头形成，第二膜片40设置于液控口15的下方。The top of the upper valve body 12 has a liquid control port 15, which serves as the liquid control port 101 of the first hydraulic control valve 100 or the liquid control port 9011 of the third hydraulic control valve 901. The liquid control port 15 can be installed by A joint is formed on the top of the upper valve body 12 , and the second diaphragm 40 is disposed below the liquid control port 15 .

如图5和图6所示，阀芯机构30设置于上阀体12中，并介于第一膜片20和第二膜片40之间。具体地，该阀芯机构30包括直动阀芯31和作动部件。上阀体12的内部开设有导向腔，该导向腔向下贯通至压力腔19，向上贯通至第二膜片40下方的腔室，直动阀芯31设置于导向腔中，该直动阀芯31的下端设置有弹性塞313与第一膜片20的中部的管体23所形成的受控孔22相对，直动阀芯31通过向下运动而能够使得弹性塞封堵受控孔22并随后压迫第一膜片20，以带动第一膜片20随后封堵阀孔17，而在直动阀芯31向上运动以撤销对受控孔22的封堵以及对第一膜片20的压迫后，如图5所示，来自进水口13的水进入到外环腔18而对第一膜片20实施向上的推力，进而使得第一膜片20通过向上变形而将第一阀孔17打开。优选地，在第一膜片20上设置有限位板24，在第一膜片20向上变形时，限位板24通过与压力腔19的顶部止挡而限制第一膜片20对阀孔17的打开量（或称开度）。As shown in FIGS. 5 and 6 , the valve core mechanism 30 is disposed in the upper valve body 12 and is between the first diaphragm 20 and the second diaphragm 40 . Specifically, the valve core mechanism 30 includes a direct-acting valve core 31 and an actuating component. A guide cavity is provided inside the upper valve body 12. The guide cavity penetrates downward to the pressure chamber 19 and upward to the chamber below the second diaphragm 40. The direct-acting valve core 31 is disposed in the guide chamber. The direct-acting valve An elastic plug 313 is provided at the lower end of the core 31 and is opposite to the controlled hole 22 formed by the tube body 23 in the middle of the first diaphragm 20. The downward movement of the direct-acting valve core 31 enables the elastic plug to block the controlled hole 22. And then presses the first diaphragm 20 to drive the first diaphragm 20 to block the valve hole 17, and the direct-acting valve core 31 moves upward to cancel the blocking of the controlled hole 22 and the first diaphragm 20. After compression, as shown in FIG. 5 , the water from the water inlet 13 enters the outer ring cavity 18 and pushes the first diaphragm 20 upward, thereby causing the first diaphragm 20 to deform upward to open the first valve hole 17 Open. Preferably, a limiting plate 24 is provided on the first diaphragm 20 . When the first diaphragm 20 deforms upward, the limiting plate 24 limits the movement of the first diaphragm 20 to the valve hole 17 by blocking with the top of the pressure chamber 19 . The amount of opening (or opening).

液控口15用于引入水而通过第二膜片40对直动阀芯31的上端进行施压，而使直动阀芯31朝下运动而实施对受控孔22的封堵以及随后对第一膜片20的压迫。The liquid control port 15 is used to introduce water and pressurize the upper end of the direct-acting valve core 31 through the second diaphragm 40 to move the direct-acting valve core 31 downward to block the controlled hole 22 and subsequently to pressure of the first diaphragm 20 .

作动部件用于为直动阀芯31提供复位力，而使得直动阀芯31在解除被液控口15的液体驱动后而向上运动至复位状态，进而撤销对受控孔22的封堵以及对第一膜片20的压迫。作动部件可以为分别设置于上阀体12以及直动阀芯31中的磁体322,321，该两个磁体322，321可通过磁斥力或磁引力为直动阀芯31提供复位，例如，如图5和图6所示，位于直动阀芯31中的磁体321的下端与位于上阀体12中的磁体322的上端磁极同极相对，这使得两个磁体322，321之间形成磁斥力，直动阀芯31利用磁斥力复位。再例如，位于直动阀芯31中的磁体322以及位于上阀体12中的磁体321异性磁极朝向相同（或者使其中一个为磁体，另一个为磁钢片），且位于直动阀芯31中的磁体321与位于上阀体12中的磁体322保持在高度上相对的位置，如此，上阀体12中的磁体322对直动阀芯31的磁体321之间形成磁引力，以带动直动阀芯31向上运动而复位。The actuating component is used to provide a reset force for the direct-acting valve core 31, so that the direct-acting valve core 31 moves upward to the reset state after being released from being driven by the liquid in the hydraulic control port 15, thereby canceling the blocking of the controlled hole 22. and pressure on the first diaphragm 20 . The actuating components can be magnets 322, 321 respectively provided in the upper valve body 12 and the direct-acting valve core 31. The two magnets 322, 321 can provide reset for the direct-acting valve core 31 through magnetic repulsion or magnetic attraction. For example, as shown in Figure 5 and 6, the lower end of the magnet 321 located in the direct-acting valve core 31 and the upper end magnetic pole of the magnet 322 located in the upper valve body 12 are opposite to each other, which causes a magnetic repulsion force to be formed between the two magnets 322, 321. The direct-acting valve core 31 uses magnetic repulsion to reset. For another example, the magnet 322 located in the direct-acting valve core 31 and the magnet 321 located in the upper valve body 12 have opposite magnetic poles facing the same direction (or one of them is a magnet and the other is a magnetic steel sheet), and they are located in the direct-acting valve core 31 The magnet 321 in the upper valve body 12 and the magnet 322 in the upper valve body 12 are maintained at a height relative position. In this way, the magnet 322 in the upper valve body 12 forms a magnetic attraction force to the magnet 321 of the direct-acting valve core 31 to drive the direct-acting valve core 31 . The moving valve core 31 moves upward to reset.

作动部件还可以是弹簧，该弹簧设置在直动阀芯31的顶部台阶与上阀体12的台阶之间，在液控口15的液体撤销对直动阀芯31驱动后，该弹簧复位而带动直动阀芯31向上运动而复位。The actuating component can also be a spring, which is arranged between the top step of the direct-acting valve core 31 and the step of the upper valve body 12. After the liquid in the liquid control port 15 cancels the drive of the direct-acting valve core 31, the spring returns. The direct-acting valve core 31 is driven to move upward and reset.

如图5和图6所示，在液控口15处的液体通过第二膜片40驱动直动阀芯31时，第二膜片40会适应性的产生变形并使得其下方的腔室容积减小，为避免第二膜片40下方的流体因无法排出而产生抗力，在导向腔的腔壁与第二膜片40的下方的腔室之间开设气体***通道33，并且，直动阀芯31在未受驱而处于高位时，其上的密封圈312位于气体***通道33的下端口的上方，而在直动阀芯31受驱后处于低位时，密封圈312位于该下端口的下方。如此，在直动阀芯31受驱向下运动过程中，气体***通道33始终打开而将第二膜片40的腔室内的气体排入下阀体11的压力腔19中以避免该腔室内的气体产生抗力，而在直动阀芯31运动至压迫第一膜片20封堵阀孔17的低位后，直动阀芯31的密封圈312将气体***通道33与压力腔19隔离，进而避免压力腔19内的液体通过气体***通道33上流。As shown in Figures 5 and 6, when the liquid at the liquid control port 15 drives the direct-acting valve core 31 through the second diaphragm 40, the second diaphragm 40 will adaptively deform and increase the volume of the chamber below it. To prevent the fluid below the second diaphragm 40 from being unable to be discharged and causing resistance, a gas discharge channel 33 is opened between the cavity wall of the guide cavity and the cavity below the second diaphragm 40, and a direct-acting valve When the core 31 is not driven and is in a high position, the sealing ring 312 on it is located above the lower port of the gas discharge channel 33. When the direct-acting valve core 31 is in a low position after being driven, the sealing ring 312 is located on the lower port. below. In this way, when the direct-acting valve core 31 is driven to move downward, the gas discharge channel 33 is always open to discharge the gas in the chamber of the second diaphragm 40 into the pressure chamber 19 of the lower valve body 11 to avoid leakage in the chamber. The gas generates resistance, and after the direct-acting valve core 31 moves to a low position that presses the first diaphragm 20 to block the valve hole 17, the sealing ring 312 of the direct-acting valve core 31 isolates the gas discharge channel 33 from the pressure chamber 19, and then The liquid in the pressure chamber 19 is prevented from flowing up through the gas discharge channel 33 .

第二膜片40可以为具有一定弹性和柔性的鼓膜，也可以为具有一定弹性和刚性的簧片。The second diaphragm 40 may be an eardrum with certain elasticity and flexibility, or may be a reed with certain elasticity and rigidity.

如图5所示若第二膜片40为鼓膜，则使得第二膜片40上方的接头的底部设置成球形面，并将直动阀芯31的顶部311也设置成球形面。当液控口15处的液体压力不足以驱动直动阀芯31时，在作动部件的作用下，直动阀芯31向上推抵第二膜片40而使得第二膜片40处于张紧状态，而当液控口15处的液体驱动直动阀芯31时，第二膜片40变形而褶皱。As shown in FIG. 5 , if the second diaphragm 40 is an eardrum, the bottom of the joint above the second diaphragm 40 is configured as a spherical surface, and the top 311 of the direct-acting valve core 31 is also configured as a spherical surface. When the liquid pressure at the liquid control port 15 is not enough to drive the direct-acting valve core 31, under the action of the actuating component, the direct-acting valve core 31 pushes upward against the second diaphragm 40 so that the second diaphragm 40 is in tension. state, and when the liquid at the liquid control port 15 drives the direct-acting valve core 31, the second diaphragm 40 deforms and wrinkles.

如图7所示，若第二膜片40为簧片，该簧片构造成在自由状态下呈向上凸出的拱形，直动阀芯31的顶部311配置成锥形结构且在中心位置形成顶针或球体结构。并且，簧片的拱形区域受驱于压力液体而朝反向变形（向下变形），限位环41用于限制簧片的变形程度以使得簧片解除受驱后能够复位。当液控口15处的液体压力达到足以能够使簧片的拱形区域向下变形并克服作动部件时，液体压迫簧片向下变形，该簧片向下变形时推抵直动阀芯31向下运动而使得直动阀芯31封堵受控孔22并随后压迫第一膜片20。而在液体压力不足以维持变形时，簧片受限位环41限制而自动复位，作动部件使得直动阀芯31复位。As shown in Figure 7, if the second diaphragm 40 is a reed, the reed is configured to be an upwardly protruding arch in the free state, and the top 311 of the direct-acting valve core 31 is configured in a conical structure and is in the center position. Form a thimble or sphere structure. Furthermore, the arched area of the reed is driven by the pressure liquid to deform in the opposite direction (deforms downward), and the limiting ring 41 is used to limit the degree of deformation of the reed so that the reed can return to its original position after being released from being driven. When the liquid pressure at the liquid control port 15 reaches enough to deform the arched area of the reed downward and overcome the actuating component, the liquid presses the reed to deform downward, and when the reed deforms downward, it pushes against the direct-acting valve core. 31 moves downward so that the direct-acting valve core 31 blocks the controlled hole 22 and subsequently presses the first diaphragm 20 . When the liquid pressure is insufficient to maintain the deformation, the reed is limited by the limiting ring 41 and automatically resets, and the actuating component causes the direct-acting valve core 31 to reset.

对于使用簧片作为第二膜片40的情况，液体压力在驱动阀芯机构30前首先需要能够驱动簧片变形，可通过计算和多次实验来获得簧片向下变形所需的液体压力。因而，利用簧片作为第二膜片40需要使液体压力满足预设的压力阈值才能够驱动阀芯机构30动作，进而避免阀芯机构30误动。For the case where a reed is used as the second diaphragm 40, the liquid pressure first needs to be able to drive the reed to deform before driving the valve core mechanism 30. The liquid pressure required for the downward deformation of the reed can be obtained through calculation and multiple experiments. Therefore, using a reed as the second diaphragm 40 requires the liquid pressure to meet a preset pressure threshold in order to drive the valve core mechanism 30 to operate, thereby preventing the valve core mechanism 30 from malfunctioning.

下面简单介绍一下该阀部件作为第一液控阀100的工作过程：The following is a brief introduction to the working process of this valve component as the first hydraulic control valve 100:

在上述的净水***中净水出水管路602关闭后，来自净水出水管路的净化水的压力在液控口15处借由第二膜片40驱动直动阀芯31向下运动，如图6所示，最终使得直动阀芯31封堵受控孔22并随后压迫第一膜片20而使得第一膜片20将阀孔17关闭，进而将自来水管路关闭601关闭。In the above-mentioned water purification system, after the purified water outlet pipe 602 is closed, the pressure of the purified water from the purified water outlet pipe drives the direct-acting valve core 31 to move downward through the second diaphragm 40 at the liquid control port 15. As shown in FIG. 6 , the direct-acting valve core 31 finally blocks the controlled hole 22 and then presses the first diaphragm 20 so that the first diaphragm 20 closes the valve hole 17 and then closes the tap water pipeline closure 601 .

在直动阀芯31封堵受控孔22后，自来水管路的原水通过平衡孔21进入到压力腔19而使得压力腔19内建立压力而与直动阀芯31一起压迫第一膜片20，由于压力腔19内的液体也对第一膜片20进行压迫，因而，净水出水管路602中以及自来水管路601中的压力出现一定的降低或波动也不会使得阀孔17打开。因而，该阀部件用作第一液控阀100还具有锁死功能。如图5所示，在限位板24靠***衡孔23的侧壁上开设有槽口241以使得流体也能够进入限位板24所包络的内部腔。After the direct-acting valve core 31 blocks the controlled hole 22, the raw water in the tap water pipe enters the pressure chamber 19 through the balance hole 21, causing pressure to build up in the pressure chamber 19 and pressing the first diaphragm 20 together with the direct-acting valve core 31. , since the liquid in the pressure chamber 19 also presses the first diaphragm 20, a certain decrease or fluctuation in the pressure in the clean water outlet pipeline 602 and the tap water pipeline 601 will not cause the valve hole 17 to open. Therefore, this valve component serves as the first hydraulic control valve 100 and also has a locking function. As shown in FIG. 5 , a notch 241 is provided on the side wall of the limiting plate 24 close to the balance hole 23 so that fluid can also enter the internal cavity enclosed by the limiting plate 24 .

当净水***中的取水端B打开后，净水出水管路602中的压力降低，使得净水出水管路602中的净化水不足以使得直动阀芯31维持压迫第一膜片20，此时，作动部件使得直动阀芯31复位，进水口13的水向上推抵第一膜片20而使阀孔17打开。如此，第一液控阀100打开使得自来水管导通以使得过滤装置能够进行制水。When the water intake port B in the water purification system is opened, the pressure in the purified water outlet pipe 602 decreases, so that the purified water in the purified water outlet pipe 602 is not enough to enable the direct-acting valve core 31 to maintain pressure on the first diaphragm 20. This When , the actuating component resets the direct-acting valve core 31 , and the water in the water inlet 13 pushes upward against the first diaphragm 20 to open the valve hole 17 . In this way, the first hydraulic control valve 100 is opened so that the water pipe is connected so that the filtering device can control water.

该阀部件作为第三液控阀901也具有相类似的工作过程，不同的是，引自第三液控阀901下游的自来水管路601来连接至液控口15。This valve component also has a similar working process as the third hydraulic control valve 901 , except that the tap water pipeline 601 from the downstream of the third hydraulic control valve 901 is connected to the liquid control port 15 .

基于上述可知，上述的阀部件可作为第一液控阀100和第三液控阀901使用。当作为两个液控阀使用时，可通过调节第二膜片40以及阀芯机构30对液控口15处水的抗力来调节第一液控阀100和第三液控阀901的打开压力和关闭压力。对于第一液控阀100而言，可将其预设打开压力设置为0.08MPa-0.16MPa，即当液控口处的水的压力小于0.08MPa，第一液控阀打开，而当液控口处的水压力大于0.16MPa时，第一液控阀关闭。Based on the above, it can be known that the above-mentioned valve components can be used as the first hydraulic control valve 100 and the third hydraulic control valve 901 . When used as two hydraulic control valves, the opening pressure of the first hydraulic control valve 100 and the third hydraulic control valve 901 can be adjusted by adjusting the resistance of the second diaphragm 40 and the valve core mechanism 30 to the water at the hydraulic control port 15 and closing pressure. For the first hydraulic control valve 100, its preset opening pressure can be set to 0.08MPa-0.16MPa, that is, when the pressure of the water at the hydraulic control port is less than 0.08MPa, the first hydraulic control valve opens, and when the hydraulic control port When the water pressure at the outlet is greater than 0.16MPa, the first hydraulic control valve is closed.

本发明的一个优选实施例提供了一种可以作为第二液控阀700的阀部件，该阀部件与可作为第一液控阀或第三液控阀的上述阀部件在关于阀体的下部结构、第一膜片、平衡孔、受控孔、以及第二膜片的结构、布置上一致，所不同的是阀芯机构的组成以及阀芯机构受驱以及解除受驱后阀孔的开闭状态。A preferred embodiment of the present invention provides a valve component that can be used as the second hydraulic control valve 700, which is connected to the above-mentioned valve component that can be used as the first hydraulic control valve or the third hydraulic control valve in relation to the lower part of the valve body. The structure, the structure, the first diaphragm, the balancing hole, the controlled hole, and the second diaphragm are the same. The difference is the composition of the valve core mechanism and the opening of the valve hole after the valve core mechanism is driven and released. closed state.

如图8和图9所示，阀芯机构30’’设置于上阀体12中，并介于第一膜片20和第二膜片40之间。阀芯机构30’包括主动部件、从动阀芯31’、第一作动部件以及第二作动部件、以及限位筒35’。从动阀芯31’位于第一膜片20的上方且下端朝向第一膜片20的受控孔22。限位筒35’固定的设置在从动阀芯31’外，该限位筒35’的顶部封闭以用于限制从动阀芯31’向上运动时的最高位置，主动部件被构造成套筒34’，套筒34’的顶部341’封闭。As shown in FIGS. 8 and 9 , the valve core mechanism 30 ″ is disposed in the upper valve body 12 and is between the first diaphragm 20 and the second diaphragm 40 . The valve core mechanism 30' includes an active component, a driven valve core 31', a first actuating component and a second actuating component, and a limiting cylinder 35'. The driven valve core 31' is located above the first diaphragm 20 and its lower end faces the controlled hole 22 of the first diaphragm 20. The limiting cylinder 35' is fixedly arranged outside the driven valve core 31'. The top of the limiting cylinder 35' is closed to limit the highest position of the driven valve core 31' when it moves upward. The active component is configured as a sleeve. 34', the top 341' of the sleeve 34' is closed.

套筒34’套设在限位筒35’外，套筒34’作为被液控口15处的液体驱动的直接受驱部件，第一作动部件包括分别设置在从动阀芯31’与套筒34’中的第一磁体321’和第二磁体322’。The sleeve 34' is set outside the limiting cylinder 35'. The sleeve 34' serves as a directly driven component driven by the liquid at the liquid control port 15. The first actuating component includes a driven valve core 31' and a driven valve core 31' respectively. First magnet 321' and second magnet 322' in sleeve 34'.

第一磁体321’和第二磁体322’的同性磁极朝向相同，在套筒34’解除受驱后，第一磁体321’低于第二磁体322’以使得套筒34’对从动阀芯31’施加磁斥力而迫使从动阀芯31’压迫第一膜片20，而在套筒34’受驱于压力液体而移动过程中，套筒34’带动第二磁体322’移动并通过限位筒35’对从动阀芯31’的限制而使得第二磁体322’低于第一磁体321’而使得套筒34’对从动阀芯31’施加反向的磁斥力，从动阀芯31’受驱于反向磁斥力而撤销对第一膜片20的压迫；第二作动部件可以是弹簧36’以使筒体复位。The same magnetic poles of the first magnet 321' and the second magnet 322' are in the same direction. After the sleeve 34' is deactivated, the first magnet 321' is lower than the second magnet 322' so that the sleeve 34' is opposite to the driven valve core. 31' exerts a magnetic repulsion force to force the driven valve core 31' to press the first diaphragm 20, and when the sleeve 34' is driven by the pressure liquid to move, the sleeve 34' drives the second magnet 322' to move and pass through the limiter. The position sleeve 35' restricts the driven valve core 31' so that the second magnet 322' is lower than the first magnet 321', so that the sleeve 34' exerts a reverse magnetic repulsion force on the driven valve core 31', and the driven valve The core 31' is driven by the reverse magnetic repulsion force to cancel the pressure on the first diaphragm 20; the second actuating component can be a spring 36' to reset the cylinder.

从套筒34’与从动阀芯31’的动作关系上看，套筒34’与从动阀芯31’受到第一作动部件与第二作动部件的配合驱动而产生相反的位置关系。即，如图8所示，当套筒34’未受驱而处于高位时，套筒34’借由第一作动部件迫使从动阀芯31’处于封堵受控孔22并压迫第一膜片20的低位，如图9所示，而当套筒34’受驱后而处于低位时，套筒34’借由第一作动部件以及限位筒35’的限位作用而迫使撤销对受控孔22的封堵及对第一膜片20的压迫而切换至高位。From the perspective of the action relationship between the sleeve 34' and the driven valve core 31', the sleeve 34' and the driven valve core 31' are driven by the cooperation of the first actuating component and the second actuating component to produce an opposite positional relationship. . That is, as shown in Figure 8, when the sleeve 34' is not driven and is in a high position, the sleeve 34' forces the driven valve core 31' to block the controlled hole 22 and press the first actuating member. The low position of the diaphragm 20 is as shown in Figure 9, and when the sleeve 34' is driven to the low position, the sleeve 34' is forced to be withdrawn by the limiting effect of the first actuating component and the limiting cylinder 35'. The controlled hole 22 is blocked and the first diaphragm 20 is pressed to switch to the high position.

本阀部件的特点是当液控口15处的液体压力大于能够驱动阀芯机构30’’时，阀芯机构30’’将阀孔17打开，进而使阀部件打开，而当液控口15处的液体压力较低而无法驱动阀芯机构30’’动作时，阀芯机构30’’保持压迫第一膜片20而使阀部件保持关闭状态。因而，本阀部件可用于第二液控阀700，以当自来水管路低于预设压力时，该阀部件处于关闭状态而将自来水管路601关闭，而当自来水管路602高于预设压力时，该阀部件将自来水管路602打开。该预设压力可设定为0.13MPa-0.18 MPa。即，当阀部件的液控口15处的液体压力小于0.13 MPa，阀部件关闭以使得自来水管路关闭，而当阀部件的液控口15处的液体压力大于0.18MPa时，自来水管路601打开，进而满足制水对自来水管路601压力的要求。The characteristic of this valve component is that when the liquid pressure at the liquid control port 15 is greater than the ability to drive the valve core mechanism 30'', the valve core mechanism 30'' will open the valve hole 17, thereby opening the valve component, and when the liquid control port 15 When the liquid pressure is low and cannot drive the valve core mechanism 30 ″ to operate, the valve core mechanism 30 ″ keeps pressing the first diaphragm 20 to keep the valve component in a closed state. Therefore, this valve component can be used in the second hydraulic control valve 700, so that when the tap water pipeline is lower than the preset pressure, the valve component is in a closed state to close the tap water pipeline 601, and when the tap water pipeline 602 is higher than the preset pressure, the valve component is in a closed state. When the pressure is high, the valve component opens the water line 602. The preset pressure can be set to 0.13MPa-0.18MPa. That is, when the liquid pressure at the liquid control port 15 of the valve component is less than 0.13 MPa, the valve component is closed to close the tap water pipeline, and when the liquid pressure at the fluid control port 15 of the valve component is greater than 0.18 MPa, the tap water pipeline 601 Open, thereby meeting the water production requirements for the pressure of the tap water pipeline 601.

另外，可通过改变阀芯机构30’’中第一作动部件的两个磁体的相对的极性方向和/或位置关系而使得套筒34’与从动阀芯31’具有同向的运动关系以及同侧的位置关系（例如，在套筒34’位于高位时，从动阀芯31’也位于远离第一膜片的高位，而在套筒34’位于低位时，从动阀芯31’也位于压迫第一膜片的低位），如此，如图12和图13所示，便使得上方的阀部件具有阀芯机构受驱时使阀部件关闭而解除受驱时阀部件打开的特点，如此，可将该结构类型的阀部件应用于第一液控阀和第三液控阀。In addition, the sleeve 34' and the driven valve core 31' can move in the same direction by changing the relative polarity direction and/or positional relationship of the two magnets of the first actuating component in the valve core mechanism 30''. relationship and the position relationship on the same side (for example, when the sleeve 34' is at a high position, the driven valve core 31' is also at a high position away from the first diaphragm, and when the sleeve 34' is at a low position, the driven valve core 31 ' is also located at a low position that compresses the first diaphragm).
