Description

混水中心Mixed water center

技术领域Technical field

本实用新型属于地暖技术领域，涉及一种混水中心。The utility model belongs to the technical field of floor heating, and relates to a water mixing center.

背景技术Background technique

随着社会的进步和市场的发展,地暖设备已经在我们日常生活中逐渐普及。地暖是指把水加热到一定温度，输送到地板下的水管散热网络，通过地板发热而实现采暖目的的一种取暖方式。地暖设备通常是一个水循环***，其中就包括混水中心，混水中心能将水温恒定控制在一个数值范围内。With the progress of society and the development of the market, floor heating equipment has gradually become popular in our daily lives. Floor heating refers to a heating method that heats water to a certain temperature and delivers it to the cooling network of water pipes under the floor. The floor heats up to achieve the purpose of heating. Floor heating equipment is usually a water circulation system, which includes a water mixing center, which can keep the water temperature constant within a range of values.

混水中心的工作原理大致为，当用户设定温度为50度时，进水温度低于50度时，进水阀门全部打开，热水进入将水温升高，当进水温度高于50度时，进水阀门自动关小，回水阀门同步打开，供回水按比例混合，自动调整为50度。市面上的混水中心的结构过于简单，无法对各种水温做出反应。例如申请号为：201320800949.0所提到的一种地暖混水装置，当分水器入口水温高于设定温度时候，则无法利用重复利用，浪费资源。还有管路内水流循环，势必会夹杂着杂质或铁屑，勋在危害使得阀体的寿命降低。所以解决上述存在的问题是我们当下刻不容缓要处理的事情。The working principle of the water mixing center is roughly as follows: when the user sets the temperature to 50 degrees, when the inlet water temperature is lower than 50 degrees, all the inlet valves are opened, and hot water enters to raise the water temperature. When the inlet water temperature is higher than 50 degrees When the temperature is high, the inlet valve is automatically closed and the return valve is opened synchronously. The supply and return water is mixed in proportion and automatically adjusted to 50 degrees. The structure of mixing water centers on the market is too simple to respond to various water temperatures. For example, the application number: 201320800949.0 refers to a floor heating water mixing device. When the inlet water temperature of the water separator is higher than the set temperature, it cannot be reused and waste resources. There is also water circulation in the pipeline, which will inevitably be mixed with impurities or iron filings, which will reduce the life of the valve body. Therefore, solving the above-mentioned problems is something we have to deal with immediately.

发明内容Summary of the invention

The lower end of the valve body has a water inlet end and a water outlet end, the right side of the valve body has a water collection end, and the upper end of the valve body has a water mixing end. The water mixing end is connected with the water inlet of the water pump, The water outlet of the water pump is connected with a detection valve, characterized in that the side of the valve body is provided with a mounting hole 1 laterally communicating with the water inlet end and a mounting hole 2 laterally communicating with the water outlet end, and the mounting hole 1 is provided with The filter screen is provided with a water passing hole connecting the two between the first installation hole and the second installation hole, and the second installation hole is provided with a pressure reducing valve core assembly that can control the opening and closing of the water passing hole, and the water mixing end There is a bypass waterway connected to the water inlet end and a circulating waterway connected to the water collecting end. The left side of the valve body is provided with an upwardly inclined installation hole 3 that communicates with the bypass waterway, and the installation hole 3 is provided with an opening and closing of the bypass waterway that can control the opening and closing of the bypass waterway. The solenoid valve core, the outlet of the bypass waterway is connected with the outlet of the circulating waterway, and the circulating waterway is provided with a check mechanism that can prevent water from flowing into the circulating waterway from the bypass waterway.

The installation hole 4 is provided with a cylindrical valve that can keep the water collection end and the water outlet always connected while controlling the opening and closing of the circulating water circuit. core.

阀体侧部设有与进水端连通的安装孔一，安装孔一内设有过滤网。热水通过进水端进入阀体内进行循环，没有经过过滤的热水中难免会存在一些杂质，如铁锈、泥沙等，这样杂质进入阀体内一起参与循环，很容易过度磨损阀体内的阀芯或水泵等，使得混水中心的寿命大大降低，同时安全性得到不到保证。在进水端设置过滤网则直接能将杂质过滤掉，不让其参与循环，大大增加阀体寿命的同时使得安全性得到大幅度提升。The side part of the valve body is provided with a mounting hole connected with the water inlet, and a filter screen is arranged in the mounting hole. Hot water enters the valve body through the water inlet and circulates. In the hot water that is not filtered, there will inevitably be some impurities, such as rust, sand, etc., so that the impurities enter the valve body and participate in the circulation together, and it is easy to excessively wear the valve core in the valve body. Or water pumps, etc., greatly reduce the life of the mixing center, and at the same time, the safety can not be guaranteed. Setting a filter screen at the water inlet can directly filter out impurities without letting them participate in the circulation, which greatly increases the life of the valve body and greatly improves the safety.

阀体侧部设有与出水端侧向连通的安装孔二，安装孔一与安装孔二之间设有过水孔，进水端与出水端通过过水孔连通，安装孔二上设有能控制过水孔启闭的减压阀芯组件。过水孔将进水端与出水端连通的好处是，当进水端进水过多时，多余的热水可以从过水孔直接进入出水端回收，这样设置使得阀体对内部水循环的温度控制精准性得到提升。The side of the valve body is provided with two mounting holes that communicate laterally with the water outlet. There is a water passing hole between the first mounting hole and the second mounting hole. The water inlet and the water outlet are connected through the water passing hole, and the second mounting hole is provided with a water passing hole. The pressure reducing valve core assembly that can control the opening and closing of the water hole. The advantage of connecting the water inlet and outlet through the water hole is that when there is too much water in the water inlet, the excess hot water can be directly recovered from the water outlet through the water hole, so that the valve body can control the temperature of the internal water circulation Accuracy is improved.

混水端内具有连通进水端的旁通水路和连通集水端的循环水路。进水端的热水能通过旁通水路流经混水端，使得热水进入循环提升混水端内的水温达到用户设定水温。而循环水路连通集水端，这样设置使得集水端中已经参与了循环的回水能重新进入混水端进行混合使得混水端水温达到设定温度从而再次进入循环。阀体外侧面上开设有向上倾斜且连通旁通水路的安装孔三，安装孔三上设置有能控制旁通水道启闭的电磁阀芯。安装孔三向上倾斜开设使得连接在安装孔三上的电磁阀芯空间占用率变低，能适应各种复杂的安装环境，大大的减少混水中心的占地面积。电磁阀芯能控制旁通水道的启闭，也能控制旁通水道的过水量，在精确的控制阀体内水温的同时大大方便了我们的使用。循环水路靠近混水端内设有止回机构，止回机构能有效地防止混水端内水压过高产生倒流现象，使得混水端的水流入集水端造成阀体无法正常使用或水流倒灌损坏阀体，止回机构的设置大大提升了阀体混水的稳定性和安全性。The mixing water end has a bypass waterway connected to the water inlet end and a circulating waterway connected to the water collecting end. The hot water at the water inlet can flow through the water mixing end through the bypass water path, so that the hot water enters the circulation and raises the water temperature in the water mixing end to reach the user set water temperature. The circulating water path is connected to the water collection end, so that the return water that has participated in the circulation in the water collection end can re-enter the mixing end for mixing so that the water temperature at the mixing end reaches the set temperature and enters the circulation again. The side of the valve body is provided with an upwardly inclined installation hole 3 which is connected to the bypass waterway, and the installation hole 3 is provided with a solenoid valve core capable of controlling the opening and closing of the bypass waterway. The installation hole 3 is inclined upward, so that the space occupancy rate of the solenoid valve core connected to the installation hole 3 is reduced, which can adapt to various complicated installation environments, and greatly reduces the area occupied by the water mixing center. The solenoid valve core can control the opening and closing of the bypass waterway, and also control the flow of the bypass waterway, which greatly facilitates our use while accurately controlling the water temperature in the valve body. A non-return mechanism is installed in the circulating water path near the mixing end. The non-return mechanism can effectively prevent the backflow phenomenon caused by excessive water pressure in the mixing end, so that the water at the mixing end flows into the collection end and the valve body cannot be used normally or the water flow is reversed. Damage to the valve body, the setting of the non-return mechanism greatly improves the stability and safety of the water mixing of the valve body.

阀体侧面上还开设有连通循环水路的安装孔四，安装孔四与出水端同轴线设置，安装孔四内设有能保持集水端与出水端始终连通的同时控制循环水路启闭的筒形阀芯。安装孔四将集水端与出水端连通，集水端的作用是连接集水器，集水器中汇聚参与了地暖循环的回水。回水温度如果过低或者过多则可以通过出水端对接外部进行回收重新加热。而当混水端内水温过高，回水则可以通过循环水路进入混水端进行混合降低水温达到用户设定温度。The side of the valve body is also provided with a mounting hole four that communicates with the circulating waterway. The mounting hole four is arranged coaxially with the water outlet. The mounting hole four is equipped with a device that can keep the water collecting end and the water outlet always connected while controlling the opening and closing of the circulating waterway. Cylindrical spool. Mounting hole four connects the water collecting end with the water outlet. The water collecting end is used to connect the water collector. The water collector collects the backwater that participates in the ground heating cycle. If the return water temperature is too low or too much, it can be recycled and reheated by connecting the water outlet to the outside. When the water temperature in the mixing water end is too high, the return water can enter the mixing water end through the circulating water path for mixing and reduce the water temperature to the user set temperature.

安装孔四内设有能保持集水端与出水端连通的同时控制循环水路启闭的筒形阀芯。这样设置的好处是，在混水端不需要回水混合时关闭循环水路则回水全部从出水端回收重新加热。当混水端需要回水混合时，则循环水路开启集水端与混水端连通，回水能通过循环水路与混水端内热水混合达到设定温度。这样设置大大提高了混水中心内的水循环效率的同时节约能源。The installation hole four is provided with a cylindrical valve core that can keep the water collecting end and the water outlet connected while controlling the opening and closing of the circulating water circuit. The advantage of this setting is that when the circulating water circuit is closed when the mixing water end does not need to be mixed, the return water is recovered from the water outlet and reheated. When the mixing water end needs to mix with the backwater, the water collecting end of the circulating waterway is connected to the water mixing end, and the backwater can be mixed with the hot water in the mixing water end to reach the set temperature through the circulating waterway. This arrangement greatly improves the water circulation efficiency in the water mixing center while saving energy.

The outer peripheral surface of the cylindrical valve core is provided with a through groove that can connect the water collection end with the inner cavity of the cylindrical valve core. The groove width of the through groove gradually increases. The cylindrical valve core can rotate relative to the circumference of the mounting hole, and the circulating water path is controlled to open and close through the through groove on the cylindrical valve core.

安装孔四孔径大于循环水路直径，这样设置的好处是当需要关闭循环水路时，安装孔四内的筒形阀芯能够完全的切断循环水路。筒形阀芯外周面上设有能将集水端与筒形阀芯内腔连通的通槽，旋转筒形阀芯，只需要通槽一部分连通集水端即能完成集水端与筒形阀芯内腔的连通，这样设置好处是能控制水流大小，方便我们调节水温。通槽的槽宽逐渐增大，这样设置使得调节水流大小时候更加精确，随着筒形阀芯的旋转，槽宽逐渐增大的通槽转动起来开口变化要比较大，能更容易控制控制水流大小，使得开启或关闭循环水路反应变得灵敏，大大提高混水效率。The diameter of the mounting hole 4 is larger than the diameter of the circulating water path. The advantage of this setting is that when the circulating water path needs to be closed, the cylindrical valve core in the mounting hole 4 can completely cut off the circulating water path. The outer circumference of the cylindrical valve core is provided with a through groove that can connect the water collecting end with the inner cavity of the cylindrical valve core. When rotating the cylindrical valve core, only a part of the through groove is connected to the water collecting end to complete the water collecting end and the cylindrical shape. The internal cavity of the spool is connected. The advantage of this setting is that the water flow can be controlled and it is convenient for us to adjust the water temperature. The groove width of the trough gradually increases. This setting makes the adjustment of the water flow more precise. With the rotation of the cylindrical valve core, the opening of the trough with the gradually increasing groove width rotates to have a larger opening change, which makes it easier to control the water flow. The size makes the reaction of opening or closing the circulating water circuit sensitive, and greatly improves the efficiency of water mixing.

在上述的混水中心中，所述安装孔四的孔口处设有环槽，环槽内设有卡簧，卡簧部分伸出环槽外并与筒形阀芯的上端面相抵靠，筒形阀芯的上端面中心设有用于与工具相配合的联结槽。In the above-mentioned mixing center, a ring groove is provided at the orifice of the mounting hole 4, a circlip is arranged in the ring groove, and the circlip part extends out of the ring groove and abuts against the upper end surface of the cylindrical valve core, The center of the upper end surface of the cylindrical valve core is provided with a coupling groove for matching with a tool.

安装孔四的孔口处设有环槽，环槽内设有卡簧，卡簧部分伸出环槽外并与筒形阀芯的上端面相抵靠。卡簧的作用是能不干涉筒形阀芯周线转动的基础上限制筒形阀芯沿周线方向运动即防止由于水流冲击造成筒形阀芯从安装孔四掉出，这样设置大大提升了筒形阀芯安装的牢靠性，提升了混水中心的安全性。筒形阀芯的上端面中心设有用于与工具相配合的联结槽，当我们需要转动筒形阀芯时候，只需要***与联结槽相互匹配的工具即可对筒形阀芯进行转动，这样设置的大大提升了本混水中心的安全性，有效地防止了筒形阀芯被人意外开启造成不必要的损失。The opening of the mounting hole four is provided with a ring groove, and a circlip is arranged in the ring groove, and the circlip part protrudes out of the ring groove and abuts against the upper end surface of the cylindrical valve core. The function of the circlip is to limit the movement of the cylindrical spool along the circumferential direction without interfering with the circumferential rotation of the cylindrical spool, that is, to prevent the cylindrical spool from falling out of the mounting hole due to the impact of the water flow. This setting is greatly improved. The installation reliability of the cylindrical valve core improves the safety of the mixing center. The center of the upper end surface of the cylindrical valve core is provided with a coupling groove for matching with the tool. When we need to rotate the cylindrical valve core, we only need to insert a tool that matches the coupling groove to rotate the cylindrical valve core. The setting greatly improves the safety of the mixing center, and effectively prevents the cylindrical valve core from being accidentally opened by people and causing unnecessary losses.

安装孔一孔径大于进水端的内径，过滤网包括一端开口一端封闭的筒形体以及固连于筒形体开口处的端盖，这样设置的好处是，过滤网能完全垄断进水端的热水，在热水进入阀体内循环前能先通过过滤网内进行过滤将杂质过滤，从而大大提高了阀体的使用寿命和安全性。安装孔一的孔口所在的面上开设有与安装孔一相连通的卡槽，端盖外周面设有卡块，卡块嵌入卡槽内。过滤网通过卡块与卡槽卡接限制其周向转动使得过滤网上的进水孔始终对着进水端设置，大大提高了过滤的效率和准确度。安装孔一的孔口外螺纹连接有防止过滤网从安装孔一内脱出的挡盖。挡盖能起到防止过滤网从安装孔一内掉出的作用，挡盖与安装孔一螺纹连接能提升两者之间的密封效果。The aperture of the installation hole is larger than the inner diameter of the water inlet. The filter includes a cylindrical body with one end open and one end closed and an end cover fixedly connected to the opening of the cylindrical body. The advantage of this arrangement is that the filter can completely monopolize the hot water at the inlet end. Before the hot water enters the valve body to circulate, the impurities can be filtered through the filter screen, which greatly improves the service life and safety of the valve body. The surface where the opening of the mounting hole one is located is provided with a card slot communicating with the mounting hole one, the outer peripheral surface of the end cover is provided with a card block, and the card block is embedded in the card slot. The filter screen is clamped with the card slot to limit its circumferential rotation, so that the water inlet hole on the filter screen is always set against the water inlet end, which greatly improves the efficiency and accuracy of filtration. The external thread of the hole of the first mounting hole is connected with a blocking cover for preventing the filter from falling out of the first mounting hole. The blocking cover can prevent the filter from falling out of the mounting hole, and the screw connection between the blocking cover and the mounting hole can improve the sealing effect between the two.

在上述的混水中心中，所述减压阀芯组件包括阀座、阀杆和阀芯，所述阀座与安装孔二固连，所述阀杆穿设在阀座上且阀杆与阀座螺纹连接，阀杆下端面上设有导向孔，所述阀芯上端部分伸入导向孔内且能相对阀杆上下运动，所述阀杆外周面上套设有弹簧，弹簧下端与阀芯上端面形成抵靠，所述阀芯下端面上还设有安装槽，安装槽设有密封垫圈，所述阀芯能通过弹簧的弹力抵靠在过水孔上端面上形成密封。In the above mixing center, the pressure reducing valve core assembly includes a valve seat, a valve stem, and a valve core, the valve seat is fixedly connected to the mounting hole, the valve stem penetrates the valve seat and the valve stem is connected to the valve seat.

具体实施方式detailed description

以下是本实用新型的具体实施例并结合附图，对本实用新型的技术方案作进一步的描述，但本实用新型并不限于这些实施例。The following are specific embodiments of the present utility model combined with the accompanying drawings to further describe the technical solution of the present utility model, but the present utility model is not limited to these embodiments.

如图1-4所示，混水中心，包括阀体1，阀体1下端设有进水端1a与出水端1b，进水端1a外周面上设有安装孔一1e，安装孔1a的孔径要大于进水端1a的内径，安装孔一1e设置在阀体1侧部且连通进水端1a。阀体1侧部还设有连通出水端1b的安装孔二1f。安装孔一1e与安装孔二1f同轴线设置且两者通过过水孔1g连通。这样设置的好处是能使得进水端1a多余的热水能直接通过过水孔1g进入出水端1b排出回收，节约资源的同时使得阀体1内的温度能得到更好的控制。安装孔一1e内设有过滤网4，进水端1a的热水中往往夹杂着铁屑、泥沙等杂质，这些杂质进入地暖循环会严重危害地暖设备的使用寿命，所以过滤网4的设置使得这些杂质在进入阀体1之前就被过滤掉，大大提高了阀体1的安全性和使用寿命。过滤网4外周面与安装孔一1e的内壁间隙配合，这样设置使得进水端1a的热水不会从过滤网4和安装孔一1e之间的间隙中通过而导致净化不彻底，提高了过滤网4的净化效率。过滤网4的外周面上设有正对进水端1a的进水孔4a1，热水能直接通过进水孔4a1进入到过滤网4内腔中，这样设置使得杂质都能被留在过滤网4的内腔内，在清洗时候只需要去除过滤网4进行冲洗即可，操作简单方便。过滤网4的上端设有端盖4b，端盖4b外周面上设有卡块4b1。安装孔一1e的孔口处设有卡槽1e1，卡块4b1卡入卡槽1e1内。这样设置给过滤网4起到一个限位的作用，防止过滤网4因为水流冲击而导致进水孔4a1歪斜，使得水中的杂质过滤不到位，大大提升了过滤网4安装的可靠性。安装孔一1e孔口处还螺纹连接有挡盖10，挡盖10的内侧面上安装有密封垫。其作用是密封垫的外周面和安装孔一1e的孔口抵靠形成软密封，挡盖10与安装孔一1e螺纹连接形成硬密封，软密封与硬密封结合形成双重密封效果，使得挡盖10与安装孔一1e之间的密封效果得到大大增强。As shown in Figure 1-4, the mixing water center includes a valve body 1.

A card slot 1e1 is provided at the opening of the mounting hole 1e, and the card block 4b1 is inserted into the card slot 1e1. This arrangement acts as a limit for the filter screen 4 to prevent the filter screen 4 from skewing the water inlet hole 4a1 due to the impact of the water flow, so that impurities in the water are not filtered out, and the reliability of the installation of the filter screen 4 is greatly improved. A blocking cover 10 is threadedly connected to the opening of the mounting hole 1e, and a sealing gasket is installed on the inner side of the blocking cover 10.
