Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a water supply valve and a water valve and a water inlet valve assembly having the water supply valve. Background Art

[0002] In the water circulation system of the wall-mounted boiler system, including the bathroom water circuit and the heating water circuit, a water inlet valve assembly is usually installed in the wall-mounted boiler system. A water inlet channel and a water replenishment channel are provided in the water inlet valve assembly. The water inlet channel is provided in the bathroom water circuit. The water inlet valve assembly also includes a water replenishment valve. A water replenishment port is often formed at the intersection of the water inlet channel and the water replenishment channel. By installing the 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 realize the on-off control between the water inlet channel and the water replenishment channel.

[0003] Currently, the common water supply valves connected to the water inlet valve are divided into inclined water supply valves and vertical water supply valves. In order to be installed on the whole machine, the inclined water supply valve has a larger opening on the bottom plate, and small animals may crawl in during subsequent use. Therefore, it is improved to a vertical water supply valve. The vertical water supply can block the holes in the bottom plate. However, since the vertical water supply valve has a bend and the flow channel at the bend is thin, it is difficult to directly process it as a whole through high-strength materials such as metal. It is generally made of plastic integral injection molding. Utility Model Content

[0004] The utility model provides a water supply valve and a water valve and a water inlet valve assembly having the water supply valve, aiming to overcome the above-mentioned problems in the prior art.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0006] On the one hand, the utility model provides a water supply valve, including a water supply valve body, a water supply valve core and an inlet and outlet water pipe. The water supply valve body has a first joint and a second joint, the axis of the first joint and the axis of the second joint intersect, and the flow channels inside the first joint and the second joint are connected via the water supply port. One end of the water supply valve core extends into the first joint of the water supply valve body to control the opening and closing of the water supply port. The interior of the inlet and outlet water pipe is formed into a hollow first inlet and outlet water flow channel, and one end of the inlet and outlet water pipe is formed as a connecting end, which extends into the second joint of the water supply valve body and is detachably connected to the inner wall of the second joint. When the connecting end is installed on the inner wall of the second joint, the first inlet and outlet water flow channel is connected to the water supply port.

[0007] As an optional technical solution, the inlet and outlet water pipes also include an inlet and outlet water pipe body, which is spaced apart from the inner wall of the second joint, and the gap between the inlet and outlet water pipe body and the inner wall of the second joint forms a second inlet and outlet water flow channel. Of the first inlet and outlet water flow channel and the second inlet and outlet water flow channel, one is an inlet flow channel and the other is an outlet flow channel, which is not limited here. Since the first inlet and outlet water flow channel and the second inlet and outlet water flow channel are respectively formed in the internal and external gaps of the inlet and outlet water pipes, the flow channels are relatively fine, making the overall processing process complicated and difficult to control the accuracy. Therefore, by processing the inlet and outlet water pipes and the water supply valve body separately and then assembling them to form the internal and external flow channels, the processing technology is simple and the processing accuracy is higher.

[0008] As an optional technical solution, a flow channel is defined within the first connector. When the water supply valve core opens the water supply channel, the first and second water supply channels are connected via the flow channel. Thus, the complete water supply channel within the water supply valve is composed of the first water supply channel, the water supply channel, the flow channel, and the second water supply channel, allowing for forward and reverse water supply.

[0009] As an optional technical solution, the water supply valve body and the inlet and outlet pipes are made of metal. Metal has good plasticity, is easy to process, and has a reliable structure.

[0010] As an optional technical solution, the water supply valve also includes an elastic seal that is sleeved onto the outer surface of the connecting end. When the connecting end is mounted on the inner wall of the second joint, the elastic seal presses against the inner wall of the second joint to form a seal. The elastic seal ensures a reliable seal at the connection between the inlet and outlet pipes and the water supply valve body.

[0011] As an optional technical solution, corresponding steps are formed on the outer surface of the connecting end and the inner wall of the second joint. When the connecting end is installed on the inner wall of the second joint, the elastic seal abuts between the steps. The steps help confirm the installation position of the inlet and outlet pipes during installation, and the abutment structure between the steps and the elastic seal further enhances the sealing effect at the connection between the inlet and outlet pipes and the water supply valve body.

[0012] As an optional technical solution, the outer surface of the end of the connection end away from the inlet and outlet pipe body is provided with an external thread, and the inner wall of the second joint is formed with a corresponding internal thread. The threaded connection is convenient for assembly and disassembly.

[0013] As an optional technical solution, at least part of the outer surface of the water inlet and outlet pipe body along the axial direction is formed into a wrench shape. Users can use tools such as wrenches to disassemble and assemble the water inlet and outlet pipes, thereby improving the reliability of the installation structure of the water inlet and outlet pipes and the water supply valve body.

[0014] As an optional technical solution, the axis of the first joint and the axis of the second joint are perpendicular to each other, which is convenient for manufacturing and processing, and can be well matched with the external structure for installation.

[0015] As an optional technical solution, the water supply valve also includes an overpressure protection assembly, disposed within the water supply valve core. The overpressure protection assembly is configured to connect the flow channel within the first connector to the outside when the fluid pressure within the first connector exceeds a preset value. When the fluid pressure within the first connector exceeds a threshold, the overpressure protection assembly connects the internal cavity of the first connector with the external environment, balancing the fluid pressure within the first connector and ensuring a stable pressure for the incoming fluid.

[0016] The second aspect of the present invention further provides a water valve having the water replenishment valve of any of the above technical solutions, wherein the water inlet channel of the water valve is connected to the first inlet and outlet water flow channel or the second inlet and outlet water flow channel.

[0017] On the other hand, the present invention further provides a water inlet valve assembly having the water supply valve of any of the above technical solutions, wherein the water inlet channel of the water inlet valve assembly is parallel to the axis of the first joint of the water supply valve.

[0018] Beneficial effects of the utility model:

[0019] According to the water supply valve and water inlet valve assembly provided by the utility model, the water supply valve can be processed separately. Only the water supply valve body and the inlet and outlet pipes need to be processed separately. After processing, the inlet and outlet pipes are inserted into the second joint of the water supply valve body and installed, and the water supply valve core is then installed into the first joint to complete the assembly. The processing of the separate water supply valve body and the inlet and outlet pipes is very simple and convenient, and there is no need to process the fine flow channel at the bend of the pipe. The processed water supply valve body and the inlet and outlet pipes only need to be assembled to form a connected flow channel. Therefore, the water supply valve body and the inlet and outlet pipes can be made of all metal, which has a simple manufacturing process, high precision, and can also be disassembled and maintained later.

[0031] First embodiment

[0032] Figure 1 This is a schematic diagram of the overall structure of a water supply valve provided by the embodiment of the utility model. Figure 1 As shown, the present invention provides a water supply valve 100 , which includes a water supply valve body 1 , a water supply valve core 2 and an inlet and outlet water pipe 3 .

[0033] in, Figure 2This is a schematic diagram of the cross-sectional structure of a water supply valve body provided by an embodiment of the present utility model. Figure 1 and Figure 2 From the perspective of the present invention, the water supply valve body 1 is an integrally formed curved pipe component, wherein the joint extending along the first direction is the first joint 11, and the joint extending along the second direction is the second joint 12, and the axes of the two joints intersect. The accompanying drawings show an example where the axes of the two joints are perpendicular to each other, but the present invention is not limited to this. The situations where the axes of the first joint 11 and the second joint 12 intersect to form a bent flow channel all fall within the scope of protection of the present invention. A connected fluid flow channel is formed in the water supply valve body 1, and the first joint 11 and the second joint 12 are connected via the water supply port 13.

[0034] One end of the water supply valve core 2 extends into the first joint 11 of the water supply valve body 1, and is used to control the opening and closing of the water supply port 13. The structure of the water supply valve core 2 is not limited here. In some preferred embodiments, one end of the water supply valve core 2 is formed as a sealing plug corresponding to the water supply port 13, and the other end is formed as a control part. The control part and the sealing plug are fixed by a connecting rod. The control part can be a hand-tightening structure (such as a hand-held part), a wrench structure, an electric structure, etc. Under the drive of the control part, the connecting rod reciprocates along the axis of the first joint 11, thereby controlling the sealing plug to open / close the water supply port 13.

[0035] Figure 3 This is a schematic diagram of the cross-sectional structure of the water inlet and outlet pipes of a water supply valve provided by an embodiment of the present utility model. Figure 1 and Figure 3 From the perspective of the structure, the inlet and outlet pipe 3 is a hollow pipe with a first water inlet and outlet channel 4 formed inside. The inlet and outlet pipe 3 includes a main body 31 and a connecting end 32, with the connecting end 32 located at one end. Preferably, the connecting end 32 is a straight pipe for ease of processing. The connecting end 32 extends into the second connector 12 of the water supply valve body 1 and is removably connected to the inner wall of the second connector 12. When the connecting end 32 is attached to the inner wall of the second connector 12, the first water inlet and outlet channel 4 communicates with the water supply port 13.

[0036] It should be noted that the detachable connection between the connecting end 32 of the inlet and outlet pipes 3 and the inner wall of the second joint 12 can be any detachable structure. For example, in some embodiments, the connecting end 32 of the inlet and outlet pipes 3 and the inner wall of the second joint 12 are connected by a thread, that is, an external thread is provided on the surface of the connecting end 32 of the inlet and outlet pipes 3, and an internal thread is provided on the inner surface of the inner wall of the second joint 12. Alternatively, in other embodiments, the connecting end 32 of the inlet and outlet pipes 3 and the inner wall of the second joint 12 are connected by a snap-fit ​​connection, for example, a protrusion is provided on the outer surface of the connecting end 32 of the inlet and outlet pipes 3, and a corresponding recess is provided on the inner wall of the second joint 12. All of the above fall within the scope of protection of the present utility model.

[0037] Specifically, when processing the water supply valve 100, it is only necessary to process the water supply valve body 1 and the inlet and outlet water pipes 3 separately. After the processing is completed, the connecting end 32 of the inlet and outlet water pipes 3 is inserted into the second joint 12 of the water supply valve body 1 for installation, and then the water supply valve core 2 is installed into the first joint 11, and the assembly is completed.

[0038] In this embodiment, the processing of the separate water supply valve body 1 and the inlet and outlet water pipes 3 is very simple and convenient, and there is no need to process the fine flow channels at the bends. The processed water supply valve body 1 and the inlet and outlet water pipes 3 only need to be assembled to form a connected flow channel, so that the water supply valve body 1 and the inlet and outlet water pipes 3 can be made of all-metal (brass, stainless steel, alloy, etc.) materials. Preferably, the water supply valve body 1 and the inlet and outlet water pipes 3 can both be made of brass. Brass has good plasticity, is easy to process, is not easy to rust, and has a reliable structure. The water supply valve 100 provided in this embodiment has a simple manufacturing process and high precision, and can also be disassembled and maintained later.

[0039] Second embodiment

[0040] In the second embodiment of the present invention, a more detailed structure of a water supply valve 100 is provided. The remaining structures are the same as those of the first embodiment and are not described in detail here.

[0041] Figure 4 This is a schematic diagram of the overall cross-sectional structure of a water supply valve provided by an embodiment of the present utility model. Figure 4 As shown, the matching structure of the water inlet and outlet pipes 3 and the second joint 12 will be further described in detail below with reference to the accompanying drawings.

[0042] Combine Figure 1 and Figure 4 From the perspective of the embodiment, the inlet and outlet pipe body 31 and the inner wall of the second joint 12 are spaced apart. Figure 4The example shown in the figure shows a case where an annular second inlet and outlet water flow channel 5 is formed between the outer wall of the inlet and outlet water pipe body 31 and the inner wall of the second joint 12, but the present invention is not limited to this. The inlet and outlet water pipe body 31 can also be partially spaced apart from the inner wall of the second joint 12, so that the gap between the inlet and outlet water pipe body 31 and the inner wall of the second joint 12 forms a strip-shaped second inlet and outlet water flow channel 5, which does not exceed the protection scope of the present invention.

[0043] In order to ensure that the first water inlet and outlet flow channel 4 and the second water inlet and outlet flow channel 5 can communicate with each other when the water supply valve core 2 opens the water supply port 13, the first water inlet and outlet flow channel 4 and the second water inlet and outlet flow channel 5 need to have a flow channel opening 6 in the first joint 11, so that a complete water supply flow channel can be formed in the water supply valve 100, specifically, the first water inlet and outlet flow channel 4 → water supply port 13 → flow channel opening 6 → second water inlet and outlet flow channel 5. The water supply source can be connected to the first water inlet and outlet flow channel 4, and the device requiring water can be connected to the second water inlet and outlet flow channel 5. In this case, the first water inlet and outlet flow channel 4 serves as the water inlet flow channel, and the second water inlet and outlet flow channel 5 serves as the water outlet flow channel. When the water supply valve core 2 opens the water supply port 13, water provided by the water source enters the water supply valve 100 through the first water inlet and outlet flow channel 4, flows through the water supply port 13 and the flow channel opening 6, and then flows out of the water supply valve 100 through the second water inlet and outlet flow channel 5 and enters the water demanding device. Alternatively, the water source for water supply can be connected to the second water inlet and outlet channel 5, and the device requiring water can be connected to the first water inlet and outlet channel 4. At this time, the first water inlet and outlet channel 4 serves as the outlet channel, and the second water inlet and outlet channel 5 serves as the inlet channel. When the water replenishment valve core 2 opens the water replenishment port 13, the water provided by the water source enters the water replenishment valve 100 through the second water inlet and outlet channel 5, flows through the water replenishment port 13 and the channel port 6, and then flows out of the water replenishment valve 100 through the first water inlet and outlet channel 4 and enters the water demanding device.

[0044] In this embodiment, since the first and second water inlet and outlet channels 4 and 5 are formed in the internal and external gaps of the inlet and outlet pipes 3, respectively, the channels are relatively fine. During the overall processing of the water supply valve 100, the manufacturing process for the first and second water inlet and outlet channels 4 and 5 is complex and difficult to control in terms of precision. Therefore, by separately processing the inlet and outlet pipes 3 and the water supply valve body 1 and then assembling them to form the internal and external channels, the processing is simplified and the processing precision is improved.

[0045] Figure 5 yes Figure 4 A magnified schematic diagram of part A. Figure 5As shown, the outer surface of the connection end 32 away from the end of the inlet and outlet pipe body 31 is provided with an external thread, and a corresponding internal thread is formed on the inner wall of the second joint 12, and at least part of the outer surface along the axial direction of the inlet and outlet pipe body 31 is formed into a wrench shape. The threaded connection is convenient for assembly and disassembly, and the wrench shape on the outer surface of the inlet and outlet pipe body 31 can facilitate users to use tools such as wrenches to disassemble and assemble the inlet and outlet pipes 3, thereby improving the reliability of the installation structure of the inlet and outlet pipes 3 and the water supply valve body 1. It should be noted that a preferred embodiment is illustrated here by taking a common tool matching structure such as a wrench shape, but the present invention is not limited to this. For some specific tools, the solution of forming a corresponding matching shape on the outer surface of the inlet and outlet pipe body 31 is also applicable to the present invention.

[0046] Preferably, the water supply valve 100 further includes an elastic seal 8, which is sleeved on the outer surface of the connection end 32. When the connection end 32 is mounted on the inner wall of the second joint 12, the elastic seal 8 presses against the inner wall of the second joint 12 to form a seal. The elastic seal 8 can be an O-ring, an elastic washer, or a sealing gasket, etc., and the elastic seal 8 can achieve a reliable seal at the connection between the inlet and outlet pipes 3 and the water supply valve body 1.

[0047] Further preferably, corresponding steps 7 are formed on the outer surface of the connecting end 32 and the inner wall of the second joint 12. When the connecting end 32 is installed on the inner wall of the second joint 12, the elastic seal 8 abuts between the steps 7. The steps 7 can help confirm the installation position of the inlet and outlet pipes 3 during installation, and the abutment structure between the steps 7 and the elastic seal 8 can further enhance the sealing effect at the connection point between the inlet and outlet pipes 3 and the water supply valve body 1.

[0048] In some preferred embodiments, the water supply valve 100 further includes an overpressure protection assembly 21 disposed within the water supply valve core 2. The overpressure protection assembly 21 is configured to connect the flow path within the first connector 11 to the outside when the fluid pressure within the first connector 11 exceeds a preset value. The specific structure of the overpressure protection assembly 21 is not limited herein; as long as the overpressure protection assembly 21 can connect the interior of the first connector 11 with the external environment when the fluid pressure within the first connector 11 exceeds a threshold, the overpressure protection assembly 21 can balance the fluid pressure within the first connector 11, thereby stabilizing the pressure of the incoming fluid.

[0049] For example, if Figure 4As shown, the overpressure protection component 21 includes a pressure relief channel 211 and a pressure relief switch 212. The pressure relief channel 211 passes through the water supply valve core 2 along the axial direction of the first joint 11. The two ends of the pressure relief channel 211 are respectively connected to the water supply port 13 and the external environment. The pressure relief switch 212 is arranged in the pressure relief channel 211. Under normal circumstances, the pressure relief channel 211 remains closed under the control of the pressure relief switch 212. When the pressure value of the fluid entering from the first water inlet and outlet channel is greater than the preset value, the pressure relief switch 212 controls the pressure relief channel 211 to open, thereby connecting the water supply port 13 with the external environment to complete the pressure relief process.

[0050] In other embodiments of the present invention, a water valve is provided, which has the water supply valve 100 in any of the above embodiments, and the water inlet channel of the water valve is connected to the first inlet and outlet water flow channel 4 or the second inlet and outlet water flow channel 5. In other embodiments of the present invention, a water inlet valve assembly is provided, such as Figure 6 As shown, the water inlet valve assembly has the water replenishing valve 100 in any of the above embodiments, and the water inlet channel 200 of the water inlet valve assembly is parallel to the axis of the first joint 11 of the water replenishing valve 100, so that the water replenishing valve core 2 at the end of the water replenishing valve 100 can extend out of the device housing, which is convenient for the user to operate.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
