Description

Technical Field

[0001] The present application belongs to the field of valve technology, and more specifically, relates to a vertical water supply valve. Background Art

[0002] The water supply valve is a valve device used to transport fluids. The water supply valve is mainly used to control the flow, pressure and direction of the fluid to ensure that the fluid in the system can be transported and distributed as needed.

[0003] At present, in a pipeline system with a water replenishment channel, a water replenishment port is often formed at the intersection of the water inlet and outlet channels and the water replenishment channel. By installing a water replenishment valve at the water replenishment port, the valve core of the water replenishment valve is used to open and close the water replenishment port to achieve on-off control between the water inlet and outlet channels and the water replenishment channel.

[0004] In the related art, water supply valves are in various forms, mostly L-shaped, T-shaped or cross-shaped. When these water supply valves are installed at the water supply port of the water system, they have structures or components that significantly protrude from the circumferential side of the valve body, so the installation space required for the water supply valves is often large, and improvement is urgently needed. Utility Model Content

[0005] In response to the defects or improvement needs of the prior art, the present application provides a vertical water supply valve and a water inlet valve, aiming to improve the problem of the large installation space occupied by the water supply valve.

[0006] The first aspect of the present application provides a vertical water supply valve adopting the following technical solution:

[0007] The present application provides a vertical water supply valve, comprising a valve body with a linear channel;

[0008] A movable sealing valve core is arranged in the linear channel of the valve body. After the valve body is adapted and coupled with the water supply port in the pipeline system, one end of the sealing valve core used for sealing faces the water supply port.

[0009] The valve body is provided with a handle for driving the sealing valve core to move between a first axial position and a second axial position of the linear channel;

[0010] When the sealing valve core is in the first position, the sealing valve core blocks the water replenishment port to cut off the water inlet and outlet channels and the water replenishment channel of the pipeline system;

[0011] After the sealing valve core moves from the first position to the second position, the sealing valve core is separated from the water replenishment port, so that the water inlet and outlet channels of the pipeline system are connected with the water replenishment channel.

[0012] Through the above technical scheme conceived by the present application, compared with the prior art, when the vertical water supply valve is installed in a pipeline system, the opening and closing of the water supply channel can be achieved by controlling the switch of the water supply port through the sealing valve core; since the vertical water supply valve of the present application is in a straight line shape as a whole, the vertical water supply valve occupies a smaller space during installation. Compared with the traditional water supply valve, the installation space can be shortened while ensuring the original function.

[0013] As further preferred, the sealing valve core includes a valve stem and a first sealing member connected to the end of the valve stem for opening and closing the water replenishing port.

[0014] As a further preferred embodiment, a mounting opening is formed at the end of the valve stem, and the first sealing member is embedded and installed in the mounting opening.

[0015] As further preferred, a second sealing member for sealing the outer circumferential surface of the valve stem and the circumferential inner wall of the linear channel is provided between the two.

[0016] As a further preference, the valve body is provided with a limiting structure for limiting the axial movable range of the sealing valve core.

[0017] As further preferred, the limiting structure includes a pin detachably connected to one end of the valve body, and end surface abutment can be formed between the pin and the sealing valve core.

[0018] As further preferred, the limiting structure includes a first protrusion fixed to the inner wall of one end of the linear channel, and an end surface conflict can be formed between the first protrusion and the sealing valve core.

[0019] As further preferred, the handle is spirally connected to the valve body along the axial direction.

[0020] As a further preferred embodiment, the handle has a bayonet, and one end of the sealing valve core is anti-detachably connected to the bayonet of the handle.

[0021] As a further preference, the valve body comprises a main body and an adapter in sequence along the axial direction, and the main body and the adapter are detachably connected.

[0022] The second aspect of the present application provides a water inlet valve adopting the following technical solution:

[0023] A water inlet valve comprises any one of the vertical water supply valves described in the first aspect.

[0024] In general, the above technical solutions conceived by this application have the following technical advantages compared with the prior art:

[0025] 1. The vertical water supply valve is in a straight line shape as a whole, so that the installation space occupied by the water inlet valve installed with the vertical water supply valve is small.

[0026] 2. An end face seal can be formed between the provided sealing gasket and the water supply port. Under the influence of water hammer, the sealing gasket is not easily cut, making it difficult for the vertical water supply valve to leak.

[0027] 3. After the handle's protrusion is assembled with the main body's thread groove, the handle can be spirally displaced along the main body's axial direction through the knob handle, thereby driving the valve stem to adjust the axial displacement. This setting does not cause the thread to be stuck, and is more stable to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] To facilitate understanding of the features of this design. For example, a Chinese patent document with publication number CN214466291U shows a new type of water inlet valve of a water circuit assembly. In this generation of products, the water inlet valve includes a first valve body and a water supply valve. The water supply valve includes a second valve body, and a connecting portion is provided at one end of the second valve body. Since the second valve body and the connecting portion are L-shaped as a whole, the water supply valve occupies a large space after being installed on the first valve body, forming a large gap, and it is easy to accumulate dirt over time, and it is also likely to become a space for insects and rats to move around.

[0037] To this end, the embodiment shown in the present application will disclose a vertical water replenishment valve and a water inlet valve, wherein the vertical water replenishment valve is generally in a straight line shape (i.e., a straight line shape). Compared with the water replenishment valve shown in the above-mentioned document, the vertical water replenishment valve is not easy to produce a large gap with other pipe components after installation, and can be directly installed in a straight hole under certain conditions; and the water inlet valve installed with the vertical water replenishment valve occupies a smaller installation space, and the overall assembly effect is better.

[0038] The following is combined with Figure 1-5 This application is described in further detail.

[0039] The present application embodiment discloses a vertical water supply valve. Figure 1-5 The vertical water supply valve comprises a valve body 1, a sealing valve core 2 and a handle 3. The valve body 1 has a linear channel 10. The sealing valve core 2 is arranged in the linear channel 10 of the valve body 1 and can move in the linear channel 10. After the valve body 1 is adapted and coupled with the water supply port 20 in the pipeline system, the end of the sealing valve core 2 used for sealing faces the water supply port 20. The handle 3 is arranged on the valve body 1, and is used to drive the sealing valve core 2 to move between the axial first position and the second position of the linear channel 10; when the sealing valve core 2 is in the first position, the sealing valve core 2 blocks the water supply port 20 to cut off the water inlet and outlet channels 30 and the water supply channel 40 of the pipeline system; after the sealing valve core 2 moves from the first position to the second position, the sealing valve core 2 is separated from the water supply port 20, so that the water inlet and outlet channels 30 and the water supply channel 40 of the pipeline system are connected.

[0040] Further, such as Figure 2-4 As shown, the sealing valve core 2 includes a valve stem 2-1 and a first sealing member 2-2 connected to the end of the valve stem 2-1 for opening and closing the water supply port 20. In this embodiment, a mounting opening 2-3 is provided at one end of the valve stem 2-1 away from the handle 3, and the first sealing member 2-2 is selected as a flexible sealing gasket, which is embedded and installed in the mounting opening 2-3.

[0041] When the sealing valve core 2 is in the first position, the sealing gasket installed at the end of the valve stem 2-1 can form an end face seal with the water replenishment port 20, thereby blocking the water replenishment port 20 and cutting off the water inlet and outlet channels 30 and the water replenishment channel 40 of the pipeline system. When the sealing valve core 2 is in the second position, the sealing gasket is separated from the water replenishment port 20, thereby opening the water replenishment port 20.

[0042] Further, such as Figure 3-4 As shown, the opening of the installation opening 2-3 is in a constricted shape, and the constricted installation opening 2-3 can restrict the sealing gasket and improve the installation stability of the sealing gasket at the installation opening 2-3.

[0043] In other embodiments, the first sealing member 2-2 can be selected as an O-ring, which is fixedly sleeved on the circumferential side of the end of the valve stem 2-1. When the sealing valve core 2 is in the first position, the O-ring can seal the gap between the valve stem 2-1 and the water supply port 20 to cut off the water inlet and outlet channels 30 and the water supply channel 40 of the pipeline system.

[0044] Furthermore, a second sealing member 2-4 is provided between the outer peripheral surface of the valve stem 2-1 and the circumferential inner wall of the linear channel 10 for sealing the two. The second sealing member 2-4 is a sealing structure such as a sealing ring that can be used for sealing. By providing the second sealing member 2-4, the sealing performance between the valve stem 2-1 and the linear channel 10 can be improved to prevent leakage of the water supply valve.

[0045] Specifically, if Figure 3-5 As shown, in this embodiment, the outer surface of the valve stem 2-1 is formed with a plurality of limiting protrusions 2-5 protruding in the circumferential direction, and the plurality of limiting protrusions 2-5 are arranged at intervals along the axial direction of the valve stem 2-1, and a receiving groove is formed between every two adjacent limiting protrusions 2-5. The second sealing member 2-4 is selected as an elastic sealing ring, which is arranged in the receiving groove. After the valve stem 2-1 is inserted into the linear channel 10 of the valve body 1, the sealing ring is sandwiched between the valve stem 2-1 and the linear channel 10 to form a seal.

[0046] Of course, in other embodiments, the second sealing member 2 - 4 may also be fixedly installed in the linear channel 10 , and it is only necessary that the second sealing member 2 - 4 be able to form a seal between the valve stem 2 - 1 and the valve body 1 .

[0047] Furthermore, in the present embodiment, the valve body 1 adopts a split design. Specifically, the valve body 1 includes a main body 1-1 and an adapter 1-2 in sequence along the axial direction. The main body 1-1 and the adapter 1-2 are detachably connected.

[0048] In this embodiment, the main body 1-1 and the adapter 1-2 are connected by threads. After the connection, the main body 1-1 and the adapter 1-2 can form the above-mentioned straight channel 10. In order to facilitate the adapter 1-2 to form a sealed connection with other pipeline components, an O-ring is provided on the outer periphery of the adapter 1-2.

[0049] Further, such as Figure 3-5 As shown, in this embodiment, a thread groove 1-3 is spirally formed along the axial direction at one end of the main body 1-1 away from the adapter 1-2; the handle 3 has a convex block adapted to the thread groove 1-3. The handle 3 has a bayonet 3-1, and the end of the sealing valve core 2 away from the adapter 1-2 is anti-detachably connected to the bayonet 3-1 of the handle 3, so that the handle 3 and the sealing valve core 2 are connected. Preferably, one end of the sealing valve core 2 is riveted into the bayonet 3-1 of the handle 3.

[0050] After the protrusion forms a matching relationship with the thread groove 1-3, the knob handle 3 can be spirally displaced along the axial direction of the main body 1-1, thereby driving the valve stem 2-1 to move axially, thereby realizing the adjustment of the axial position of the valve stem 2-1.

[0051] Compared with the traditional method of threaded connection between the handle 3 and the main body 1-1 by setting fine threads, the thread groove 1-3 in this solution has a larger groove size, a higher fault tolerance rate, and can prevent the thread from being stuck when water hammer occurs. It also has a longer service life and is easy for after-sales.

[0052] Furthermore, in order to prevent the valve stem 2-1 from detaching from the linear channel 10, the valve body 1 is provided with a limiting structure for limiting the axial range of movement of the sealing valve core 2. The limiting structure includes but is not limited to a pin 4, a first protrusion 5, a limiting plate, a limiting ring, etc. arranged in the valve body 1.

[0053] For example, the limiting structure includes a pin 4 detachably connected to one end of the valve body 1, and when the sealing valve core 2 moves to abut against the pin 4, an end surface abutment is formed between the sealing valve core 2 and the pin 4. For another example, the limiting structure includes a first protrusion 5 fixed to the inner wall of one end of the linear channel 10, and when the sealing valve core 2 moves to abut against the first protrusion 5, an end surface abutment is formed between the sealing valve core 2 and the first protrusion 5.

[0054] Specifically, if Figure 3-5As shown, in this embodiment, the main body 1-1 has a socket, and the socket of the main body 1-1 is provided with a plug pin 4; correspondingly, one end of the valve stem 2-1 protrudes along the circumferential direction to form a second protrusion 2-6 for forming an end surface conflict with the plug pin 4. The inner wall of the adapter 1-2 protrudes to form a first protrusion 5, and the first protrusion 5 can form an end surface conflict with the limiting protrusion 2-5 carried by the valve stem 2-1. Since the provided plug pin 4 and the first protrusion 5 can both limit the valve stem 2-1, the range of movement of the valve stem 2-1 is limited, and the valve stem 2-1 is difficult to detach from the valve body 1.

[0055] The embodiment of the present application also discloses a water inlet valve, which includes a first valve body and any one of the vertical water supply valves mentioned above. The first valve body includes but is not limited to the first valve body in the water inlet valve listed above: a Chinese patent document with publication number CN214466291U.
