Description

Technical Field

[0001] This application relates to the field of valve technology, and in particular to a water supply valve and a water inlet valve. Background Technology

[0002] A water supply valve is a valve device used to transport fluids, primarily controlling the flow rate, pressure, and direction of the fluid to ensure that the fluid in the system can be transported and distributed as needed. Currently, in pipeline systems with water supply channels, a water supply port is often formed at the intersection of the inlet / outlet channel and the water supply channel. By installing a water supply valve at the water supply port, the valve core opens and closes this port to control the flow between the inlet / outlet channel and the water supply channel. When the water supply valve needs to be opened, rotating the handle in one direction to connect the inlet / outlet channel and the water supply channel may cause the valve stem to exceed its specified stroke, resulting in thread jamming and affecting the sealing performance of the water supply valve. Utility Model Content

[0003] This application provides a water supply valve and an inlet valve, which can reduce damage to the water supply valve and improve its sealing performance.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] In a first aspect, embodiments of this application provide a water supply valve, including a first body and a first valve stem. The first body has a first hole, a first end face, and a second end face. Along the axial direction of the first hole, the first hole penetrates the first end face and the second end face, and the first end face is perpendicular to the axis of the first hole. The first valve stem is threaded to the first hole. Along the axial direction of the first valve stem, the first valve stem has a first end and a second end disposed opposite to each other. The first end extends out of the first hole and is located on the side of the first end face away from the second end face. The first end is provided with a boss. Along the radial direction of the first valve stem, the boss protrudes from the outer peripheral surface of the first valve stem. Along the axial direction of the first valve stem, the projection of the boss at least partially overlaps with the projection of the first end face.

[0006] The water supply valve proposed in this application embodiment has a boss protruding from the outer circumference of the first valve stem at the first end. Along the axial direction of the first valve stem, the projection of the boss at least partially overlaps with the projection of the first end face. When the first valve stem retracts relative to the first hole, the boss moves toward the first end face. When the boss abuts against the first end face, the first valve stem stops moving, and the water supply valve is in a fully engaged state. The abutment between the boss and the first end face restricts the excessive movement of the first valve stem, reduces the jamming of the mating threads between the first valve stem and the first body, thereby reducing damage to the water supply valve and improving its sealing performance.

[0007] Optionally, the water supply valve also includes a handle, which is located at the second end along the axial direction of the first valve stem, and the projection of the handle at least partially overlaps with the projection of the second end face.

[0008] In the above scheme, the handle is located at the second end. Turning the handle rotates the first valve stem to move within the first hole, causing the first end to move toward or away from the first end face, thereby opening or closing the water supply valve. When the handle is turned to move the first valve stem away from the first end face, the handle comes into contact with the second end face, restricting further movement of the first valve stem. At this time, the water supply valve is in the closed state.

[0009] Optionally, the boss is constructed as a ring along the circumference of the first valve stem.

[0010] In the above scheme, the annular boss can provide more uniform support and constraint along the circumference of the first valve stem, effectively reducing the swaying and offset of the valve stem during movement, making the movement of the first valve stem more stable, enabling the first valve stem to move accurately within the specified stroke range, reducing the failure of the water supply valve or system abnormality caused by excessive valve stem stroke, and improving the accuracy and reliability of water supply valve control.

[0011] Optionally, the boss includes a plurality of sub-bosses, which are spaced apart along the circumference of the first valve stem.

[0012] In the above scheme, each sub-protrusion is a protruding structure that protrudes radially from the first valve stem. Multiple sub-protrusions can provide uniform support and constraint for the first valve stem along the circumference of the first valve stem, while saving materials.

[0013] Optionally, along the axial direction of the first valve stem, the outer periphery of the boss cross-section is polygonal or circular.

[0014] In the above scheme, along the circumference of the first valve stem, the outer edge of the projection of the boss can be polygonal or circular, so that the boss can uniformly abut against the first end face, providing stable and uniform support for the first valve stem, enabling the first valve stem to move stably within the specified stroke, reducing the swaying and offset of the valve stem, thereby reducing thread damage between the first valve stem and the first body, and improving the life and sealing performance of the water supply valve.

[0015] Optionally, the first hole includes a first section and a second section, the inner diameter of the first section is larger than the inner diameter of the second section, and the first section is closer to the first end face than the second section; the water supply valve also includes an abutment portion, the abutment portion is disposed on the outer peripheral surface of the first valve stem and located on the side of the boss facing the first end face, and when the boss abuts against the first end face, the abutment portion engages with the first section.

[0016] In the above scheme, the abutment part is provided at the first end to enhance the strength of the first valve stem. When the first valve stem is in the stroke between the closed state and the fully open state of the water supply valve, the abutment part can effectively stabilize the first valve stem, reduce water hammer impact that causes the first valve stem to deviate from the axis of the first hole, thereby reducing the occurrence of poor sealing of the water supply valve.

[0017] Optionally, the outer peripheral surface of the first valve stem is provided with a plurality of first grooves, which are spaced apart along the axial direction of the first valve stem; the water supply valve also includes a plurality of first sealing rings, each of which is disposed in a corresponding first groove and abuts against the inner peripheral surface of the first hole.

[0018] In the above scheme, the first sealing ring is fitted on the first valve stem, which can effectively reduce fluid leakage from the gap between the first valve stem and the first body. The combined action of multiple first sealing rings can improve the reliability of the seal and ensure that the water supply valve has a good sealing effect.

[0019] In addition, multiple first sealing rings ensure that the force exerted on the first valve stem is uniform when it moves within the first hole, making the movement of the first valve stem within the first hole more stable and reducing the swaying and deviation of the first valve stem during movement.

[0020] Secondly, this application provides a water inlet valve, including a first valve body and a water replenishment valve as described in any of the above embodiments. The first valve body has a main channel and a water replenishment channel communicating with the main channel. The water replenishment valve is disposed on the first valve body to selectively connect the water replenishment channel with the main channel.

[0021] The embodiment of this application proposes that when the water level in the system is insufficient, turning the handle moves the first valve stem within the first hole, causing the boss to move towards the first end face. The boss restricts the stroke of the first valve stem, opening the water supply valve and connecting the water supply channel and the main channel. Fluid enters the water supply channel from the main channel, thus replenishing the system's water supply. This inlet valve has a simple overall structure, occupies less space, is easy to install, and achieves the same technical effect as the water supply valve.

[0022] Optionally, the outer peripheral surface of the first valve stem is further provided with a second groove, the second groove being located on the side of the boss away from the first end face; the water supply valve further includes a second sealing ring, the second sealing ring being located in the second groove; the first valve body has a mounting cavity, at least a portion of the water supply valve is located in the mounting cavity, the water supply channel includes a first water supply channel and a second water supply channel, the mounting cavity has a first opening and a second opening, the second sealing ring selectively abuts against the inner wall of the mounting cavity so that the first opening connects or disconnects the mounting cavity and the first water supply channel, and the second opening connects the second water supply channel and the mounting cavity.

[0023] In the above scheme, when the handle is turned, the first valve stem moves along the first hole until the handle abuts against the second end face. At this point, the first end of the first valve stem abuts against the first opening, and the first sealing ring seals the first opening. The first sealing ring blocks the mounting cavity and the first water supply channel, thereby closing the water supply valve. When the handle is turned, the first valve stem moves along the first hole toward the boss and abuts against the first end face. The first end of the first valve stem disengages from the first opening, thereby opening the water supply valve.

[0024] Optionally, the water inlet valve further includes a third sealing ring, which is sleeved on the end of the first body near the first end face and abuts against the inner circumferential surface of the mounting cavity.

[0025] In the above scheme, the third sealing ring is fitted onto the first body, which can effectively reduce fluid leakage from the gap between the first valve body and the first body. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

[0045] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0048] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0049] In related technologies, water supply valves come in various forms, often L-shaped, T-shaped, or cross-shaped. This application uses a vertical water supply valve to address the issue of large installation space requirements. However, when opening the water supply valve, misoperation, such as continuously rotating the handle in the same direction, may cause the valve stem to exceed its specified stroke, resulting in thread seizure and preventing the valve from closing, thus affecting its sealing performance. Therefore, to solve this problem, a vertical water supply valve with a fixed stroke is designed. This valve stem is fixed, reducing the likelihood of thread seizure due to the valve stem exceeding its specified stroke, which would otherwise affect the valve's performance.

[0050] Firstly, reference Figures 1 to 3 This application provides a water supply valve 100, which includes a first body 102 and a first valve stem 104. The first body 102 has a first hole 1020, a first end face 1021, and a second end face 1022. Along the axial direction of the first hole 1020, the first hole 1020 passes through the first end face 1021 and the second end face 1022. The first end face 1021 is perpendicular to the axis of the first hole 1020. The first valve stem 104 is threaded to the first hole 1020 and extends along the axis of the first valve stem 104. The first valve stem 104 has a first end 1041 and a second end 1042 disposed opposite to each other. The first end 1041 extends out of the first hole 1020 and is located on the side of the first end face 1021 away from the second end face 1022. The first end 1041 is provided with a boss 106. Along the radial direction of the first valve stem 104, the boss 106 protrudes from the outer peripheral surface of the first valve stem 104. Along the axial direction of the first valve stem 104, the projection of the boss 106 at least partially overlaps with the projection of the first end face 1021.

[0051] The first body 102 has a first hole 1020 that penetrates the first end face 1021 and the second end face 1022. The first valve stem 104 is threaded to the first hole 1020, and the first end 1041 of the first valve stem 104 extends out of the first hole 1020 on the side close to the first end face 1021. The first end 1041 is provided with a boss 106 protruding from the outer peripheral surface of the first valve stem 104. The first valve stem 104 can move in the first hole 1020. When the first valve stem 104 extends relative to the first hole 1020, the boss 106 moves away from the first end face 1021. When the first valve stem 104 retracts relative to the first hole 1020, the boss 106 moves close to the first end face 1021.

[0052] The water supply valve 100 proposed in this application embodiment has a boss 106 protruding from the outer peripheral surface of the first valve stem 104 at the first end 1041. Along the axial direction of the first valve stem 104, the projection of the boss 106 at least partially overlaps with the projection of the first end face 1021. When the first valve stem 104 retracts relative to the first hole 1020, the boss 106 moves toward the first end face 1021. When the boss 106 abuts against the first end face 1021, the first valve stem 104 stops moving, and the water supply valve 100 is in the fully engaged state. The abutment between the boss 106 and the first end face 1021 restricts the excessive movement of the first valve stem 104, reduces the jamming of the mating threads between the first valve stem 104 and the first body 102, thereby reducing damage to the water supply valve 100 and improving the sealing performance of the water supply valve 100.

[0053] It should be understood that, along the axial direction of the first valve stem 104, the projection of the boss 106 at least partially overlaps with the projection of the first end face 1021. This could be that the projection of the boss 106 falls within the projection of the first end face 1021, or that the projection of the boss 106 coincides with the projection of the first end face 1021, or other possible situations. As long as the first valve stem 104 moves toward the first end face 1021 to its maximum stroke when the water supply valve 100 is in the open state, the boss 106 can abut against the first end face 1021 to limit the continued movement of the first valve stem 104.

[0054] Optionally, refer to Figures 1 to 3 The water supply valve also includes a handle 108, which is located at the second end 1042. Along the axial direction of the first valve stem 104, the projection of the handle 108 at least partially overlaps with the projection of the second end face 1022.

[0055] The first end 1041 and the second end 1042 of the first valve stem 104 both extend out of the first hole 1020. The first end 1041 extends out of the first hole 1020 on the side near the first end face 1021, and the second end 1042 extends out of the first hole 1020 on the side near the second end face 1022. A handle 108 is provided at the second end 1042. Turning the handle 108 can rotate the first valve stem 104 to move within the first hole 1020, so that the first end 1041 moves toward or away from the first end face 1021, thereby opening or closing the water supply valve 100.

[0056] Along the axial direction of the first valve stem 104, the projection of the handle 108 at least partially overlaps with the projection of the second end face 1022. The projection of the side end face of the handle 108 toward the second end face 1022 can be larger than the projection of the second end face 1022, or the projection of the side end face of the handle 108 toward the second end face 1022 can be located within the projection of the second end face 1022, or other possible situations, as long as the handle 108 can abut against the second end face 1022 when one end of the first valve stem 104 moves away from the first end face 1021 to the maximum stroke.

[0057] The handle 108 turns the first valve stem 104, causing the first end 1041 to move away from the first end face 1021. When the handle 108 comes into contact with the second end face 1022, it can restrict the first valve stem 104 from moving further. At this time, the water supply valve 100 is in the closed state.

[0058] In this application, when the water supply valve 100 needs to be opened, the handle 108 is turned, and the first valve stem 104 moves within the first hole 1020 until the boss 106 abuts against the first end face 1021. At this time, the first end face 1021 restricts the first valve stem 104 from continuing to move. At this time, the water supply valve 100 is in a fully open state, and the first valve stem 104 is at its minimum stroke. When the water supply valve 100 needs to be closed, the handle 108 is turned, and the first valve stem 104 moves within the first hole 1020 until the handle 108 abuts against the second end face 1022. At this time, the second end face 1022 restricts the first valve stem 104 from continuing to move. At this time, the water supply valve 100 is in a closed state, and the first valve stem 104 is at its maximum stroke. This application limits the maximum and minimum stroke of the first valve stem 104 by the contact between the handle 108 and the second end face 1022 of the first body 102 and the contact between the boss 106 and the first end face 1021 of the first body 102, thereby reducing damage to the threads between the first valve stem 104 and the first body 102, thus reducing damage to the water supply valve 100 and reducing the impact on the sealing performance of the water supply valve 100.

[0059] Optionally, the boss 106 is constructed as a ring structure along the circumference of the first valve stem 104. When the boss 106 abuts against the first end face 1021, the ring-shaped boss 106 can provide more uniform support and constraint along the circumference of the first valve stem 104, effectively reducing the swaying and offset of the valve stem during movement, making the movement of the first valve stem 104 more stable, and enabling the first valve stem 104 to move accurately within the specified stroke range. This reduces the risk of malfunction of the water supply valve 100 or system abnormalities caused by excessive valve stem stroke, and improves the control accuracy and reliability of the water supply valve 100.

[0060] Optionally, the boss 106 includes multiple sub-bosses, which are spaced apart along the circumference of the first valve stem 104. Each sub-boss is a protruding structure that protrudes radially from the first valve stem 104. The multiple sub-bosses can provide uniform support and constraint for the first valve stem 104 along the circumference of the first valve stem 104, while saving materials.

[0061] Optionally, along the axial direction of the first valve stem 104, the outer periphery of the boss 106 cross-section is polygonal or circular. Along the circumferential direction of the first valve stem 104, the outer edge of the projection of the boss 106 can be polygonal or circular, so that the boss 106 can uniformly abut against the first end face 1021, providing stable and uniform support for the first valve stem 104, enabling the first valve stem 104 to move stably within a specified stroke, reducing valve stem sway and offset, thereby reducing thread damage between the first valve stem 104 and the first body 102, and improving the life and sealing performance of the water supply valve 100.

[0062] Optionally, refer to Figure 2 The first hole 1020 includes a first section 1020a and a second section 1020b. The inner diameter of the first section 1020a is larger than the inner diameter of the second section 1020b. The first section 1020a is closer to the first end face 1021 than the second section 1020b. The water supply valve 100 also includes an abutment portion 110. The abutment portion 110 is provided on the outer peripheral surface of the first valve stem 104 and is located on the side of the boss 106 facing the first end face 1021. When the boss 106 abuts against the first end face 1021, the abutment portion 110 is engaged with the first section 1020a.

[0063] The abutment portion 110 is provided at the first end 1041 of the first valve stem 104 and is located on the side of the boss 106 facing the first end face 1021. When the boss 106 abuts against the first end face 1021, the abutment portion 110 fits into the first section 1020a. The outer diameter of the abutment portion 110 is smaller than the outer diameter of the boss 106. It can be that the outer peripheral surface of the abutment portion 110 abuts against the inner peripheral surface of the first section 1020a. The abutment portion 110 is provided at the first end 1041 to enhance the strength of the first valve stem 104. When the first valve stem 104 is in the stroke between the closed state and the fully open state of the water supply valve 100, the abutment portion 110 can effectively stabilize the first valve stem 104, reduce water hammer impact that causes the first valve stem 104 to deviate from the axis of the first hole 1020, thereby reducing the occurrence of poor sealing of the water supply valve 100.

[0064] Optionally, refer to Figure 2 and Figure 3 The outer peripheral surface of the first valve stem 104 is provided with a plurality of first grooves, which are spaced apart along the axial direction of the first valve stem 104; the water supply valve 100 also includes a plurality of first sealing rings 112, each of which is located in a corresponding first groove and abuts against the inner peripheral surface of the first hole 1020.

[0065] The first sealing ring 112 is sleeved on the first valve stem 104, which can effectively reduce fluid leakage from the gap between the first valve stem 104 and the first body 102. Multiple first sealing rings 112 work together, and when one first sealing ring 112 is damaged, the other sealing rings can still continue to play a sealing role, thereby improving the reliability of the seal and ensuring that the water supply valve 100 has a good sealing effect.

[0066] In addition, since the first valve stem 104 moves within the first hole 1020, the multiple first sealing rings 112 make the force on the first valve stem 104 within the first hole 1020 uniform, making the movement of the first valve stem 104 within the first hole 1020 more stable and reducing the shaking and deviation of the first valve stem 104 during movement.

[0067] Secondly, refer to Figure 4 This application provides a water inlet valve 200, including a first valve body 206 and a water replenishment valve 100 as described in any of the above embodiments. The first valve body 206 has a main channel 202 and a water replenishment channel 204 communicating with the main channel 202. The water replenishment valve 100 is disposed on the first valve body 206 to selectively connect the water replenishment channel 204 with the main channel 202.

[0068] The water inlet valve 200 proposed in this application embodiment has a first valve body 206 with a main channel 202. The main channel 202 is used to inject a large flow of water into the system. The water replenishment channel 204 is connected to the main channel 202. When the water in the system is insufficient, the handle 108 is turned, the first valve stem 104 moves in the first hole 1020, and the boss 106 moves toward the first end face 1021. The water replenishment valve 100 is opened, connecting the water replenishment channel 204 and the main channel 202. Fluid enters the water replenishment channel 204 from the main channel 202, thereby realizing the water replenishment of the system. The inlet valve 200 of this application has the same technical effect as the water replenishment valve 100 described in any of the above embodiments. It can limit the stroke of the first valve stem 104 by the boss 106 abutting against the first end face 1021 and the handle 108 abutting against the second end face 1022, thereby reducing the probability of the water replenishment valve 100 being damaged due to excessive movement of the first valve stem 104. In addition, the inlet valve 200 has a simple overall structure, occupies less space, and is easy to install.

[0069] Optionally, refer to Figure 4 The outer peripheral surface of the first valve stem 104 is also provided with a second groove, which is located on the side of the boss 106 away from the first end face 1021; the water supply valve 100 also includes a second sealing ring 114, which is located in the second groove; the first valve body 206 has a mounting cavity 2060, at least a portion of the water supply valve 100 is located in the mounting cavity 2060, the water supply channel 204 includes a first water supply channel 2041 and a second water supply channel 2042, the mounting cavity 2060 has a first opening 2061 and a second opening 2062, the second sealing ring 114 selectively abuts against the inner wall of the mounting cavity 2060 so that the first opening 2061 connects or disconnects the mounting cavity 2060 and the first water supply channel 2041, and the second opening 2062 connects the second water supply channel 2042 and the mounting cavity 2060.

[0070] The first valve body 206 has an installation cavity 2060 for installing the water supply valve 100. The first water supply channel 2041 is connected to the main channel 202. The second water supply channel 2042 is connected to the installation cavity 2060 through the second opening 2062. The first end 1041 of the first valve stem 104 has a second groove, and a second sealing ring 114 is provided in the second groove. The second sealing ring 114 is located on the side of the boss 106 away from the first end face 1021. When the handle 108 is turned, the first valve stem 104 moves along the first hole 1020 until the handle 108 abuts against the second end face 1022, at which point the first end 1041 of the first valve stem 104 abuts against the first opening. 2061, the first sealing ring 112 seals the first opening 2061, and the first sealing ring 112 blocks the mounting cavity 2060 and the first water supply channel 2041, thereby closing the water supply valve; turning the handle 108, the first valve stem 104 moves along the first hole 1020 toward the boss 106 near the first end face 1021, the first end 1041 of the first valve stem 104 disengages from the first opening 2061, the first water supply channel 2041 communicates with the mounting cavity 2060 through the first opening 2061, and the first water supply channel 2041 communicates with the second water supply channel 2042 through the mounting cavity 2060 and the second opening 2062. When the first valve stem 104 moves to the point where the boss 106 abuts against the first end face 1021, the first water supply channel 2041 and the second water supply channel 2042 are in a fully open state, that is, the water supply valve is in a fully open state. Of course, the stroke of the first valve stem 104 moving toward the boss 106 and abutting the first end face 1021 can be determined according to the specific flow requirements, thereby adjusting the opening of the water supply valve 100.

[0071] It should be understood that the mounting cavity 2060 includes a peripheral surface and a bottom surface. The first body 102 mates with the peripheral surface of the mounting cavity 2060. The first opening 2061 is located on the bottom surface of the mounting cavity 2060. When the first end 1041 of the first valve stem 104 abuts against the first opening 2061, the first sealing ring 112 abuts against the bottom surface of the mounting cavity 2060.

[0072] Optionally, the water inlet valve 200 also includes a third sealing ring 116, which is sleeved on one end of the first body 102 near the first end face 1021 and abuts against the inner circumferential surface of the mounting cavity 2060.

[0073] The third sealing ring 116 is fitted onto the first body 102, which can effectively reduce fluid leakage from the gap between the first valve body 206 and the first body 102.

[0074] In this application, the first body 102 is installed in the mounting cavity 2060 of the first valve body 206. The first end 1041 of the first valve stem 104 extends out of the first hole 1020 near the first end face 1021, and the second end 1042 extends out of the first hole 1020 near the second end face 1022. The first end 1041 is provided with a boss 106, and the second end 1042 is provided with a handle 108. When the water supply valve 100 needs to be opened, the handle 108 is turned, and the second sealing ring 114 on the first valve stem 104 disengages from the bottom surface of the mounting cavity 2060. The mounting cavity 2060 is connected to the first water supply channel 2041. Fluid can enter the mounting cavity 2060 from the main channel 202 through the first water supply channel 2041, and then enter the second water supply channel 2042 through the second opening 2062. When the first valve stem 104 moves to the point where the boss 106 abuts against the first end face 1021, the water supply valve 100 is fully opened. Of course, the opening state of the water supply valve 100 can be determined according to the actual situation.

[0075] When the water supply valve 100 needs to be closed, the handle 108 is turned in the opposite direction. The first end 1041 of the first valve stem 104 moves toward the first opening 2061. When the first valve stem 104 moves to the point where the handle 108 abuts against the second end face 1022, the first end 1041 blocks the first opening 2061, and the second sealing ring 114 abuts against the bottom surface of the mounting cavity 2060, thereby disconnecting the first water supply channel 2041 and the second water supply channel 2042.

[0076] For example, when the water supply valve 100 is fully open and the boss 106 abuts against the first end face 1021, the distance between the boss 106 and the first end face 1021 is 22mm-30mm, and the distance between the boss 106 and the side of the handle 108 furthest from the second end face 1022 is 52mm-65mm. When the water supply valve 100 is closed, the distance between the boss 106 and the first end face 1021 is 8mm-14mm.

[0077] This application limits the maximum outward movement of the first valve stem 104 relative to the first opening 2061 by setting a boss 106, and limits the movement of the first valve stem 104 toward the first opening 2061 by the handle 106, thereby reducing the excessive displacement of the first valve stem 104, thereby reducing damage to the water supply valve 100, improving the sealing performance of the water supply valve 100, and reducing leakage of the water supply valve 100.
