Description
本新型創作涉及一種單向閥，特別是一種傘閥。本新型創作還涉及一種包括上述傘形閥的微型水泵。The novel creation relates to a one-way valve, especially an umbrella valve. The novel creation also relates to a miniature water pump including the umbrella valve.
微型流體泵用於將流體，諸如液體或氣體（例如，水或空氣），引入泵體內，對所述流體進行加熱和/或加壓，然後以預定的參數排出泵。根據微型流體泵的應用場合的不同，所述預定的參數可以是所排出流體的壓力、溫度、流量、總體積等。此外，在一些情況下，還希望泵的噪音盡可能低。Miniature fluid pumps are used to introduce a fluid, such as a liquid or gas (eg, water or air), into the pump body, heat and / or pressurize the fluid, and then discharge the pump with predetermined parameters. According to different applications of the micro fluid pump, the predetermined parameters may be pressure, temperature, flow rate, total volume, etc. of the discharged fluid. In addition, in some cases it is desirable that the noise of the pump be as low as possible.
流體泵中設置有用於覆蓋流路的閥，在操作中，所述閥在流體的作用下打開以使流體通過，並能在流體通過後閉合以防止流體回流。微型流體泵體積微小，比如，其泵體的長度一般只有幾釐米，從而泵的每一個組成部件的體積都很小，但又必須相互配合以在令人滿意的精度要求下工作。例如，上面提到的閥，其是控制流體泵的性能（例如流量、噪音等）的關鍵部件，必須同時具備良好的密封能力和開合回應能力。The fluid pump is provided with a valve for covering the flow path. In operation, the valve is opened under the action of the fluid to allow the fluid to pass through, and can be closed after the fluid passes to prevent the fluid from flowing back. Miniature fluid pumps have a small volume. For example, the length of the pump body is generally only a few centimeters, so the volume of each component of the pump is small, but they must cooperate with each other to work with satisfactory accuracy requirements. For example, the valve mentioned above is a key component to control the performance of the fluid pump (such as flow, noise, etc.), and must have both good sealing ability and opening and closing response capabilities.
本新型創作提供一種單向閥，其具有非常微小的尺寸，同時具備良好的密封能力和開合回應能力。This new creation provides a one-way valve, which has a very small size, and at the same time has good sealing ability and opening and closing response capabilities.
根據本新型創作的單向閥，其特徵在於，所述單向閥為傘閥，其具有傘面部分，所述傘面部分具有覆蓋相應流體通路的第一側，所述第一側形成為刀紋面。刀紋面應理解為以下涵義：機加工（例如車刀或銑刀）之後在模具表面形成刀紋，未經拋光或打磨，單向閥通過橡膠注塑成型，其傘面部分的覆蓋流體通路的那一側對應于形成有上述模具表面，由此形成為刀紋面。當閥的覆蓋流體通路的一側為光滑表面時，該側會在較大面積上與閥座接觸，從而形成吸盤現象，造成傘面部分不易打開，阻礙流體通過。將覆蓋流體通路的一側形成為刀紋面，由於刀紋面的表面紋理，能夠避免上述吸盤現象，提高單向閥的回應靈敏度，精准開合。The one-way valve created according to the present invention is characterized in that the one-way valve is an umbrella valve having an umbrella face portion, the umbrella face portion has a first side covering a corresponding fluid passage, and the first side is formed as Knife pattern surface. The knife surface should be understood as the following meaning: after machining (such as a turning tool or milling cutter), a knife pattern is formed on the surface of the mold without polishing or grinding. The one-way valve is molded by rubber injection molding, and its umbrella surface covers the That side corresponds to the surface on which the above-mentioned mold is formed, thereby forming a knife-shaped surface. When the side of the valve covering the fluid path is a smooth surface, the side will contact the valve seat over a large area, thereby forming a suction cup phenomenon, which makes the umbrella surface part difficult to open and hinders the passage of fluid. The side covering the fluid passage is formed into a knife-shaped surface. Due to the surface texture of the knife-shaped surface, the above-mentioned sucker phenomenon can be avoided, the response sensitivity of the check valve can be improved, and the opening and closing can be accurately performed.
優選地，所述刀紋面的刀紋具有同心圓或螺旋線的形式。這樣的設置可形成逐層密封，實現了更佳的密封性能。Preferably, the knife pattern of the knife pattern surface has the form of concentric circles or spiral lines. Such an arrangement can form a layer-by-layer seal, achieving better sealing performance.
優選地，所述單向閥還具有沿一軸線延伸的傘棒部分，所述傘面部分的第一側具有的環形傾斜面遠離所述傘棒部分傾斜。由於流體中攜帶雜質和異物，這些雜質和異物易於沉積在傘閥的覆蓋流體通路的一側，也即位於傘閥的該側和閥座之間，將傘面部分頂起，可能會使傘閥不能密封流體通路。在該側上設置傾斜面能夠避免流體通過傘閥時將其攜帶的雜質沉積在傘閥上，以及將之前可能沉積的一些異物帶走，從而提升了傘閥的自清潔能力。而且，由於傾斜角度的設置，在傘面部分更易打開的同時，也沒有降低單向閥的密封性能。Preferably, the one-way valve further has an umbrella rod portion extending along an axis, and an annular inclined surface provided on a first side of the umbrella surface portion is inclined away from the umbrella rod portion. Because the fluid carries impurities and foreign materials, these impurities and foreign materials are easy to deposit on the side of the umbrella valve that covers the fluid path, that is, between the side of the umbrella valve and the valve seat. Raising the umbrella surface part may cause the umbrella The valve cannot seal the fluid path. Setting an inclined surface on this side can prevent the impurities carried on the umbrella valve from being deposited on the umbrella valve when the fluid passes through the umbrella valve, and take away some foreign materials that may have been deposited before, thereby improving the self-cleaning ability of the umbrella valve. In addition, due to the setting of the inclination angle, the sealing performance of the check valve is not reduced while the umbrella surface portion is easier to open.
優選地，所述傘面部分還具有與第一側相反的第二側，所述第二側具有平面形式。由此傘面部分可為扁平形式。扁平傘面部分具有易於打開的優點，且節省空間，能夠使與之配合的部件具有更小的尺寸。Preferably, the umbrella face portion further has a second side opposite to the first side, and the second side has a flat form. Thereby the canopy part can be in a flat form. The flat umbrella surface portion has the advantage of being easy to open, saves space, and enables the parts to be matched with it to have a smaller size.
優選地，所述傘棒部分設置有止擋部，該止擋部位於所述傘棒部分的中部。在單向閥安裝在閥座上之後，止擋部可與相應的安裝孔配合以防止在泵操作期間單向閥從閥座脫離。Preferably, the umbrella rod portion is provided with a stopper portion, and the stopper portion is located at a middle portion of the umbrella rod portion. After the check valve is installed on the valve seat, the stopper can cooperate with the corresponding mounting hole to prevent the check valve from detaching from the valve seat during the operation of the pump.
優選地，所述傘面部分的第一側設置有傘根部分，所述傘棒部分從所述傘根部分延伸。傘根部分不僅增加了傘形閥的強度使其即使經過多次且長期的打開和閉合也不易在該處斷裂，而且提高了傘形閥的相應能力以及開合準確性。Preferably, an umbrella root portion is provided on a first side of the umbrella face portion, and the umbrella rod portion extends from the umbrella root portion. The umbrella root part not only increases the strength of the umbrella valve, making it difficult to break there even after repeated and long-term opening and closing, but also improves the corresponding ability of the umbrella valve and the accuracy of opening and closing.
優選地，所述傘棒部分設置有引導部，所述引導部從所述止擋部延伸至所述傘棒部分的末端。Preferably, the umbrella rod portion is provided with a guide portion, and the guide portion extends from the stop portion to an end of the umbrella rod portion.
根據本新型創作的傘閥形式的單向閥具有的尺寸是微小的，但是在這樣微小尺寸的條件下，所述閥同時具備良好的密封能力、自清潔能力和開合回應能力。優選地，所述傘面部分的直徑為6.30毫米。優選地，所述傘面部分的厚度為0.35毫米。優選地，所述傘棒部分的從所述止擋部至所述傘面部分的部段的直徑為1.3毫米。The one-way valve in the form of an umbrella valve according to the present invention has a small size, but under such a small size condition, the valve also has good sealing ability, self-cleaning ability, and opening and closing response ability. Preferably, the diameter of the umbrella portion is 6.30 mm. Preferably, the thickness of the umbrella face portion is 0.35 mm. Preferably, a diameter of a section of the umbrella rod portion from the stop portion to the umbrella surface portion is 1.3 mm.
本新型創作還涉及一種微型流體泵，其特徵在於，所述微型流體泵包括：馬達，用於為提供使所述流體泵進行工作的動力；泵體，安裝至所述馬達；泵蓋，覆蓋在所述泵體上；其中，所述泵體包括閥座，所述閥座具有用於引入流體和/或用於排出流體的流體通路，且其中，所述閥座上設置有用於相應流體通路的根據前述申請專利範圍中任一項所述的單向閥。The novel creation also relates to a miniature fluid pump, which is characterized in that the miniature fluid pump includes: a motor for providing power to make the fluid pump work; a pump body, which is mounted to the motor; a pump cover, covering On the pump body; wherein the pump body includes a valve seat having a fluid passage for introducing a fluid and / or discharging a fluid, and wherein the valve seat is provided with a corresponding fluid The check valve according to any one of the scope of the aforementioned patent application.

請參考圖1，本新型創作借助微型流體泵100來具體說明根據本新型創作的單向閥，即，單向閥在該流體泵100中使用。該流體泵100可以是隔膜泵。根據不同的應用，流體泵100可以是水泵或氣泵。Please refer to FIG. 1, the present invention uses a micro fluid pump 100 to specifically explain the check valve according to the present invention, that is, the check valve is used in the fluid pump 100. The fluid pump 100 may be a diaphragm pump. According to different applications, the fluid pump 100 may be a water pump or an air pump.
如圖1所示，流體泵100可包括泵體20、覆蓋在泵體20上的泵蓋10。泵體20可包括閥座21、隔膜座22和殼體23。膈膜座22上可設置有可壓縮隔膜部60。流體泵100可還包括馬達30，用於提供使所述流體泵進行工作的動力。流體泵100可具有用於流體流入的進入通道和用於排出流體的排出通道，該進入通道和排出通道可通過流體泵100的多個部件上的相應部分來建立。以圖1和2中所示的取向，泵蓋10、閥座21、隔膜座22和殼體23以該順序從上至下組裝在一起，例如，通過卡簧40組裝在一起。馬達30安裝至殼體23。流體泵100可限定縱向軸線Y，即，從馬達30至泵蓋10延伸所沿的軸線。As shown in FIG. 1, the fluid pump 100 may include a pump body 20 and a pump cover 10 covering the pump body 20. The pump body 20 may include a valve seat 21, a diaphragm seat 22, and a housing 23. The diaphragm holder 22 may be provided with a compressible diaphragm portion 60. The fluid pump 100 may further include a motor 30 for providing power for operating the fluid pump. The fluid pump 100 may have an intake channel for fluid inflow and an exhaust channel for exhausting the fluid, and the intake channel and exhaust channel may be established by corresponding portions on various parts of the fluid pump 100. In the orientation shown in FIGS. 1 and 2, the pump cover 10, the valve seat 21, the diaphragm seat 22, and the housing 23 are assembled together in this order from top to bottom, for example, by a snap spring 40. The motor 30 is mounted to the case 23. The fluid pump 100 may define a longitudinal axis Y, that is, an axis along which the motor 30 extends to the pump cover 10.
如圖2所示，泵蓋10可形成流體泵100的進入通道和/或排出通道的一部分。例如，泵蓋10可具有進口11和出口12，流體通過該進口11進入流體泵100，並經過該出口12流出流體泵100，由此，泵蓋10的進口11可形成流體泵100的進入通道的一部分，出口12可形成流體泵100的排出通道的一部分。As shown in FIG. 2, the pump cover 10 may form part of an inlet passage and / or an outlet passage of the fluid pump 100. For example, the pump cover 10 may have an inlet 11 and an outlet 12 through which fluid enters the fluid pump 100 and exits the fluid pump 100 through the outlet 12, whereby the inlet 11 of the pump cover 10 may form an entry channel for the fluid pump 100 The outlet 12 may form part of a discharge passage of the fluid pump 100.
泵體20的閥座21上可設置有用於排出流體的流出通路，可還設置有用於引入流體的流入通路，例如用於流體流入/流出的孔（未示出）。流出通路和流入通路均可稱為流體通路。在圖2所示的例子中，閥座21的流出通路位於所述閥座21的中央區域中，而流入通路圍繞該中央區域。單向閥可設置在閥座21上，用於覆蓋流體通路。具體地，單向閥可包括覆蓋流入通路的單向進入閥70和/或覆蓋流出通路的單向排出閥80。單向進入閥70可位於閥座21和膈膜座22之間。單向排出閥80可位於閥座21和泵蓋10之間。The valve seat 21 of the pump body 20 may be provided with an outflow passage for discharging fluid, and may further be provided with an inflow passage for introducing fluid, such as a hole (not shown) for fluid inflow / outflow. Both the outflow passage and the inflow passage can be referred to as a fluid passage. In the example shown in FIG. 2, the outflow passage of the valve seat 21 is located in a central region of the valve seat 21, and the inflow passage surrounds the central region. A check valve may be provided on the valve seat 21 to cover the fluid passage. Specifically, the one-way valve may include a one-way inlet valve 70 covering an inflow passage and / or a one-way discharge valve 80 covering an outflow passage. The one-way access valve 70 may be located between the valve seat 21 and the diaphragm seat 22. The one-way discharge valve 80 may be located between the valve seat 21 and the pump cover 10.
如圖2所示，單向閥70、80可以為傘閥。具體請參考圖3，圖3示出了單向進入閥70的例子。單向排出閥80可與單向進入閥70具有相似的結構，不再贅述。傘閥形式的單向閥70具有傘面部分71，該傘面部分71可具有大致圓盤的形式，直徑大約為6.3毫米。單向閥70可還具有傘棒部分72，其可從傘面部分71的中心沿軸線72Y延伸。傘棒部分72可穿過相應的安裝孔（未示出）以安裝單向閥70。軸線72Y可與流體泵100的縱向軸線Y平行。圖3示出了單向閥70的軸向截面圖。As shown in FIG. 2, the check valves 70 and 80 may be umbrella valves. For details, please refer to FIG. 3, which shows an example of the one-way access valve 70. The one-way discharge valve 80 may have a similar structure to the one-way inlet valve 70 and will not be described again. The one-way valve 70 in the form of an umbrella valve has an umbrella face portion 71 which may have the form of a substantially disc with a diameter of approximately 6.3 mm. The check valve 70 may further have an umbrella rod portion 72 that may extend from the center of the umbrella surface portion 71 along the axis 72Y. The umbrella rod portion 72 may pass through a corresponding mounting hole (not shown) to mount the check valve 70. The axis 72Y may be parallel to the longitudinal axis Y of the fluid pump 100. FIG. 3 shows an axial cross-sectional view of the check valve 70.
傘面部分71可具有覆蓋閥座21的流入通路的第一側71A和與第一側71A相反的第二側71B。該第二側71B可具有平面形式，由此傘面部分71可為扁平圓盤形式，其厚度（即，沿軸線Y的長度）大致為0.35毫米。扁平傘面部分具有易於打開的優點，且節省空間，能夠使與之配合的部件具有更小的尺寸。The umbrella face portion 71 may have a first side 71A covering the inflow passage of the valve seat 21 and a second side 71B opposite to the first side 71A. The second side 71B may have a flat form, and thus the umbrella portion 71 may be in the form of a flat disc, and its thickness (ie, the length along the axis Y) is approximately 0.35 mm. The flat umbrella surface portion has the advantage of being easy to open, saves space, and enables the parts to be matched with it to have a smaller size.
如圖3和4所示，傘面部分71可還設置有傘根部分73，傘根部分73可以是圍繞傘棒部分72的矮圓臺，傘棒部分72可從該傘根部分73沿軸線72Y延伸。傘根部分73的設置不會影響傘面部分71的第一側71A對流體通路的密封，例如，傘根部分73的厚度（沿軸線72Y的長度）可以為大致0.35毫米。傘根部分73不僅增加了傘形閥70的強度使其即使經過多次且長期的打開和閉合也不易在該處斷裂，而且提高了傘形閥的相應能力以及開合準確性。As shown in FIGS. 3 and 4, the umbrella surface portion 71 may further be provided with an umbrella root portion 73, which may be a short round platform surrounding the umbrella rod portion 72, and the umbrella rod portion 72 may be along the axis from the umbrella root portion 73. 72Y extended. The arrangement of the umbrella root portion 73 does not affect the sealing of the fluid path on the first side 71A of the umbrella surface portion 71. For example, the thickness (length along the axis 72Y) of the umbrella root portion 73 may be approximately 0.35 mm. The umbrella root portion 73 not only increases the strength of the umbrella valve 70 so that it is not easy to break there even after repeated and long-term opening and closing, but also improves the corresponding ability of the umbrella valve and the accuracy of opening and closing.
接下來參考圖3和4來詳細描述傘面部分71。傘面部分71的第一側71A可具有環形傾斜面710，該環形傾斜面710可以佔據第一側71A的一部分或全部。圖4示出了從圖3中傘棒部分的自由端部觀察的單向閥的示意圖。圖4中，傘面部分71的外周邊緣與虛線圓712之間的部分限定出了環形傾斜面710。由此，在該例子中，環形傾斜面710佔據第一側71A的一部分。還如圖3所示，該環形傾斜面710可遠離傘棒部分72傾斜。“遠離”的意思是，環形傾斜面710與傘棒部分72的軸線72Y之間的夾角大於90度。環形傾斜面710相對於與傘棒部分72的軸線72Y垂直的平面P的夾角β在1.20至1.60度的範圍內。由於流體（特別是水）中攜帶雜質和異物，這些雜質和異物易於沉積在傘閥的覆蓋流體通路的一側，也即位於傘閥的該側和閥座之間，將傘面部分頂起，可能會使傘閥不能密封流體通路。在該側上設置傾斜面能夠避免流體通過傘閥時將其攜帶的雜質沉積在傘閥上，以及將之前可能沉積的一些異物帶走，從而提升了傘閥的自清潔能力。而且，由於傾斜角度的設置，在傘面部分71更易打開的同時，也沒有降低單向閥的密封性能。在優選的情況下，環形傾斜面710相對於與傘棒部分72的軸線72Y垂直的平面P的夾角β為1.30至1.50度。更優選地，例如，該夾角β為1.43度。Next, the umbrella portion 71 will be described in detail with reference to FIGS. 3 and 4. The first side 71A of the umbrella face portion 71 may have an annular inclined surface 710 that may occupy a part or all of the first side 71A. FIG. 4 shows a schematic view of the check valve viewed from the free end of the umbrella rod portion in FIG. 3. In FIG. 4, a portion between the outer peripheral edge of the umbrella surface portion 71 and the dotted circle 712 defines an annular inclined surface 710. Thus, in this example, the annular inclined surface 710 occupies a part of the first side 71A. As also shown in FIG. 3, the annular inclined surface 710 may be inclined away from the umbrella rod portion 72. “Away” means that the included angle between the annular inclined surface 710 and the axis 72Y of the umbrella rod portion 72 is greater than 90 degrees. The included angle β of the annular inclined surface 710 with respect to the plane P perpendicular to the axis 72Y of the umbrella rod portion 72 is in the range of 1.20 to 1.60 degrees. Because the fluid (especially water) carries impurities and foreign matter, these impurities and foreign matter are easily deposited on the side of the umbrella valve that covers the fluid path, that is, between the side of the umbrella valve and the valve seat, lifting the umbrella surface part It may prevent the umbrella valve from sealing the fluid path. Setting an inclined surface on this side can prevent the impurities carried on the umbrella valve from being deposited on the umbrella valve when the fluid passes through the umbrella valve, and take away some foreign materials that may have been deposited before, thereby improving the self-cleaning ability of the umbrella valve. Moreover, due to the setting of the inclination angle, while the umbrella surface portion 71 is easier to open, the sealing performance of the check valve is not reduced. In a preferred case, the included angle β of the annular inclined surface 710 with respect to the plane P perpendicular to the axis 72Y of the umbrella rod portion 72 is 1.30 to 1.50 degrees. More preferably, for example, the included angle β is 1.43 degrees.
此外，單向閥70的傘面部分71的第一側71A可形成為刀紋面。刀紋面應理解為以下涵義：機加工（例如車刀或銑刀）之後在模具表面形成刀紋，未經拋光或打磨，單向閥70通過橡膠注塑成型，其傘面部分71的第一側71A對應于形成有上述模具表面，由此形成為刀紋面。當閥的覆蓋流體通路的一側為光滑表面時，該側會在較大面積上與閥座接觸，從而形成吸盤現象，造成傘面部分不易打開，阻礙流體通過。將覆蓋流體通路的一側形成為刀紋面，由於刀紋面的表面紋理，能夠避免上述吸盤現象，提高單向閥的回應靈敏度，精准開合。刀紋面的刀紋可具有同心圓或螺旋線的形式，以形成逐層密封，實現了更佳的密封性能。應注意的是，傘面部分71的第一側71A形成為刀紋面可獨立於該第一側71A具有環形傾斜面710的結構。也就是說，無論該第一側71A是否具有環形傾斜面710，其都可以形成為刀紋面。In addition, the first side 71A of the umbrella surface portion 71 of the check valve 70 may be formed as a knife-shaped surface. The knife surface should be understood as the following meaning: after machining (such as a turning tool or a milling cutter), a knife pattern is formed on the surface of the mold without polishing or grinding. The check valve 70 is injection-molded by rubber. The side 71A corresponds to a surface on which the above-mentioned mold is formed, thereby being formed into a knife-shaped surface. When the side of the valve covering the fluid path is a smooth surface, the side will contact the valve seat over a large area, thereby forming a suction cup phenomenon, which makes the umbrella surface part difficult to open and hinders the passage of fluid. The side covering the fluid passage is formed into a knife-shaped surface. Due to the surface texture of the knife-shaped surface, the above-mentioned sucker phenomenon can be avoided, the response sensitivity of the check valve can be improved, and the opening and closing can be accurately performed. The knife pattern on the knife pattern surface can have the form of concentric circles or spiral lines to form a layer-by-layer seal, achieving better sealing performance. It should be noted that the first side 71A of the umbrella surface portion 71 is formed into a structure in which the knife-shaped surface may have an annular inclined surface 710 independently of the first side 71A. That is, regardless of whether the first side 71A has an annular inclined surface 710 or not, it can be formed as a knife-shaped surface.
接下來參考圖3繼續描述傘形單向閥70。如圖3所示，單向閥70的傘棒部分72可具有自由末端721且可設置有止擋部722，該止擋部722位於傘棒72的中部。“位於中部”的意思是，止擋部722位於傘根部分73與傘棒72的末端721之間，而不是必須位於整個傘棒部分72的中間位置處。該止擋部722可具有大致球形的形狀，其直徑略大於相應的安裝孔的直徑且在擠壓變形時能通過所述安裝孔。當傘棒部分72穿過相應的安裝孔以安裝單向閥70之後，止擋部722可與該安裝孔配合以防止在流體泵100的操作期間單向閥70從閥座脫離。傘棒部分72的位於於止擋部722與傘面部分（傘根部分73）之間的部段724的長度和直徑應與閥座21的流體通道的長度和直徑相配合，既確保單向閥有良好回應能力，同時又保持密封。例如，部段724的直徑可以為1.3毫米。Next, the umbrella check valve 70 will be described with reference to FIG. 3. As shown in FIG. 3, the umbrella rod portion 72 of the check valve 70 may have a free end 721 and may be provided with a stopper portion 722, which is located in the middle of the umbrella rod 72. “Locating in the middle” means that the stopper portion 722 is located between the umbrella root portion 73 and the end 721 of the umbrella rod 72, instead of having to be located at the middle position of the entire umbrella rod portion 72. The stopping portion 722 may have a substantially spherical shape, and its diameter is slightly larger than the diameter of the corresponding mounting hole and can pass through the mounting hole when it is squeezed and deformed. After the umbrella rod portion 72 passes through the corresponding mounting hole to mount the check valve 70, the stopper portion 722 may cooperate with the mounting hole to prevent the check valve 70 from being detached from the valve seat during the operation of the fluid pump 100. The length and diameter of the section 724 of the umbrella rod portion 72 between the stopper portion 722 and the umbrella surface portion (the umbrella root portion 73) should be matched with the length and diameter of the fluid passage of the valve seat 21 to ensure a unidirectional The valve has a good response while maintaining a seal. For example, the diameter of section 724 may be 1.3 millimeters.
此外，傘棒部分72可設置有引導部723，引導部723從止擋部722延伸至傘棒部分72的末端721。引導部723可用於引導傘棒部分72穿過相應的安裝孔，其直徑小於安裝孔的直徑以在安裝時順利通過。當單向閥70安裝在閥座21上之後，引導部723可被去除。In addition, the umbrella rod portion 72 may be provided with a guide portion 723 that extends from the stop portion 722 to a distal end 721 of the umbrella rod portion 72. The guide portion 723 can be used to guide the umbrella rod portion 72 through the corresponding mounting hole, and its diameter is smaller than the diameter of the mounting hole for smooth passage during installation. After the check valve 70 is installed on the valve seat 21, the guide portion 723 may be removed.
