Description

Technical Field

[0001] This utility model relates to the field of tax valve technology, and in particular to a quick-install valve. Background Technology

[0002] In urban water supply and drainage systems, domestic water systems, air conditioning systems, heating systems, and other water systems, valves typically have conventional threaded ports at both ends. In practical applications, valves in system pipelines or between valves are currently mostly connected using threads. To ensure a good seal, PTFE tape is usually wrapped around the threaded connection during installation. This is not only cumbersome, but also requires a high level of experience from the installers. Improper use of PTFE tape will directly affect the installation quality and easily lead to leaks. Furthermore, when connecting two valves, a threaded connector is usually used, with both ends of the connector threaded to the valves on both sides, creating two possible leak points and a significant risk of leakage.

[0003] Therefore, there is an urgent need to provide a quick-install valve to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-install valve that enables the valve to be installed and disassembled quickly.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A quick-install valve includes a valve body, which includes a first connector and a second connector. The first connector is a socket structure or a spigot structure. The spigot structure can be sealed and inserted into the socket structure. The socket structure has a through hole that penetrates its inner wall, and the outer wall of the spigot structure has a limiting groove. The second connector is connected to a union structure, which is used to connect with a threaded connector or a PPR connector.

[0007] As an optional solution, the union structure is a union nut assembly, which includes a first union nut and a retaining ring. The first union nut is used for threaded connection with the threaded connector. A groove is provided on the outer side wall of the second connector, and the retaining ring is accommodated in the groove. One end of the first union nut is fitted onto the outside of the second connector and is provided with a first stop edge. The inner diameter of the first stop edge is smaller than the outer diameter of the retaining ring, and the first stop edge is axially limited to the side of the retaining ring away from the end face of the second connector.

[0008] As an optional solution, the union nut assembly further includes a first sealing gasket, which is a flat gasket disposed inside the first union nut. One side of the first sealing gasket abuts against the end face of the second connector, and the other side abuts against the end face of the threaded connector.

[0009] As an optional solution, the union structure is a PPR nut assembly, which includes a second union nut for connecting to the PPR connector. One end of the second union nut is threaded to the outer side wall of the second connector, and the other end is provided with a second stop edge. One end of the PPR connector is provided with a limiting boss. The inner diameter of the second stop edge is smaller than the inner diameter of the second union nut and smaller than the outer diameter of the limiting boss. The limiting boss is inserted into the second union nut and axially limited to the inner side of the second stop edge.

[0010] As an optional solution, the PPR nut assembly further includes a second sealing gasket, which is disposed inside the second union nut and is sealed between the end face of the second connector and the end face of the PPR connector.

[0011] As an alternative, one of the second sealing gasket near the second connector and the second connector near the second sealing gasket is provided with a protrusion, and the other is provided with a groove, the protrusion being inserted into the groove.

[0012] As an alternative, the socket structure is provided with a boss that extends tangentially along the socket structure, and the insertion hole is formed within the boss.

[0013] As an optional solution, the number of the protrusions is set to one;

[0014] Alternatively, the number of the protrusions may be set to two, with the two protrusions respectively disposed on opposite sides of the socket structure.

[0015] As an optional solution, a sealing assembly is provided on the outer wall of the socket structure. The sealing assembly includes a first sealing groove formed on the outer wall of the socket structure and a first sealing ring disposed in the first sealing groove. The first sealing groove is located between the limiting groove and the end face of the socket structure.

[0016] As an optional solution, the quick-install valve is a ball valve, gate valve, globe valve, check valve, or pressure reducing valve.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a quick-installation valve. First, by setting the first connector at one end of the valve to a socket or spigot structure, a limiting groove is provided on the spigot structure, and a socket hole is provided on the socket structure. This allows it to mate with a pipe or another valve that also has a corresponding socket or spigot structure. An insert is inserted into the socket hole and limited within the limiting groove. The insert, socket, and limiting groove form a plug-in assembly that can be detachably fixed at the connection point. This facilitates quick assembly, disassembly, and maintenance between the valve and the pipe or between valves, reducing installation difficulty and cost. Furthermore, it eliminates the need for Teflon tape during installation, simplifying installation, significantly shortening installation time, reducing connection leaks, and improving connection reliability. Second, by setting a union structure on the second connector at the other end of the valve, this union structure can be used with readily available water pipe fittings (such as threaded connectors or PPR connectors), improving compatibility and greatly enhancing installation convenience.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] Example 1

[0036] Reference Figure 1 This embodiment provides a quick-install valve, which can be a ball valve, gate valve, globe valve, check valve, pressure reducing valve, etc. This embodiment takes the connection of a gate valve with a threaded connector and pipeline 20 as an example. Of course, it can also be connected with other valves. These valves can be commonly used valves in waterworks, such as ball valves, gate valves, globe valves, check valves, pressure reducing valves, etc.

[0037] Specifically, as shown in the figure, the quick-install valve includes a valve body 1, which includes a first connector 11 and a second connector 12. The first connector 11 is used to connect to the pipeline 20. The first connector 11 is a socket structure 2, and the connector of the pipeline 20 is a spigot structure 3. The spigot structure 3 can be sealed and inserted into the socket structure 2. The second connector 12 is connected to a union structure, which is used to connect to the threaded connector of the water meter end distributor in the water circuit.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, the socket structure 2 has a through-hole 21 penetrating its inner wall, and the spigot structure 3 has a limiting groove 31 on its outer wall. A single pin 10 passes through the through-hole 21 and is simultaneously confined within the limiting groove 31, thus achieving an axial fixed connection between the socket structure 2 and the spigot structure 3. Disassembly is simple; just pull the single pin 10 outwards. Disassembly and assembly are convenient and quick. To facilitate direction adjustment during assembly of the quick-install valve, the limiting groove 31 surrounds the outer wall of the spigot structure 3, and for ease of machining, the trajectory of the limiting groove 31 is perpendicular to the central axis of the spigot structure 3.

[0039] The inner diameter of the socket structure 2 is greater than or equal to the outer diameter of the spigot structure 3. After assembly, the spigot structure 3 is inserted into the socket structure 2 and is axially limited by a straight rod-shaped single pin 10 (the socket hole 21 and the single pin 10 correspond one-to-one). Figure 2 As can be seen, the single pin 10 extends into the socket 21, and part of the single pin 10 also falls into the limiting groove 31 of the socket structure 3 at the same time, thereby forming the axial limiting of the first connector 11 and the pipeline 20 while completing the docking.

[0040] In this embodiment, an axial limit is achieved using a single socket 21 and a single pin 10. However, this utility model is not limited to this form and other structural forms can also be used, such as using a U-shaped pin (one U-shaped pin with two sockets 21) or two single pins 10 (two single pins 10 with two sockets 21), etc.

[0041] like Figure 1 As shown, a sealing assembly is provided on the outer wall of the socket structure 3. The sealing assembly includes a first sealing groove (not shown in the figure due to perspective) formed on the outer wall of the socket structure 3, and a first sealing ring 5 disposed within the first sealing groove. The first sealing groove is located between the limiting groove 31 and the end face of the socket structure 3. The first sealing ring 5 is closer to the end face of the socket structure 3 and is mainly used for sealing between the socket structure 3 and the side wall of the socket structure 2 to prevent liquid leakage.

[0042] Furthermore, the sealing assembly also includes a second sealing groove (not shown in the figure due to perspective) formed on the outer wall of the socket structure 3, and a second sealing ring 6 disposed within the second sealing groove. The second sealing groove and the first sealing groove are respectively disposed on both sides of the limiting groove 31. The second sealing ring 6 has a thinner wire diameter than the first sealing ring 5 and mainly serves to seal and prevent dust.

[0043] Therefore, the quick-install valve provided in this embodiment, firstly, by setting the first connector 11 at one end of the valve as a socket structure 2, can be socketed and mated with a pipe 20 or another valve that is also equipped with a corresponding spigot structure 3. A spigot hole 21 is provided on the socket structure 2, and a limiting groove 31 is provided on the spigot structure 3. A single pin 10 is inserted into the spigot hole 21 and limited within the limiting groove 31. The single pin 10, the spigot hole 21, and the limiting groove 31 form a plug-in assembly that can be detachably fixed at the connection point. This facilitates quick disassembly, assembly, and maintenance between the valve and the pipe 20 or between valves, reducing installation difficulty and cost. Moreover, no Teflon tape is required during installation, which not only simplifies installation but also greatly shortens installation time, while reducing connection leakage points and improving connection reliability. Secondly, by connecting a union structure to the second connector 12 at the other end of the valve, the union structure can be matched with existing water pipe fittings (threaded connectors), resulting in better compatibility and greatly improving installation convenience.

[0044] In this embodiment, as Figure 2 As shown, the socket structure 2 is provided with a boss 22, which extends tangentially along the socket structure 2. The insertion hole 21 is formed within the boss 22 and simultaneously penetrates the inner wall of the socket structure 2. The boss 22 increases the length of the insertion hole 21, thereby improving the reliability of the insertion connection. (Continue referring to the appendix...) Figure 2 The end face of the boss 22 is flat, and the port of the socket 21 is opened on this flat surface, which facilitates positioning and machining of the socket 21. It is worth mentioning that the aforementioned boss 22 is not necessary, and the socket 21 can also be directly opened on the socket structure 2.

[0045] like Figure 2 As shown, in this embodiment, the number of protrusions 22 is set to one, corresponding one-to-one with the straight rod-shaped single pin 10. In another optional embodiment, the number of protrusions 22 is set to two, with the two protrusions 22 respectively disposed on opposite sides of the socket structure 2. The two protrusions 22 correspond to the installation of the U-shaped pin or the installation of the two single pins 10.

[0046] Optionally, such as Figure 2 As shown, the boss 22 has a threaded hole at the port of the insertion hole 21, which communicates with the insertion hole 21. The outer wall of the single pin 10 has an external thread, and the single pin 10 is connected to the threaded hole through the external thread. This threaded fastening connection reduces the risk of the single pin 10 falling off.

[0047] Furthermore, the diameter of the threaded hole is larger than the diameter of the insertion hole 21, and a third sealing ring 7 is embedded at the bottom of the threaded hole, which is fitted over the single pin 10. The third sealing ring 7 serves two purposes: firstly, to seal and prevent dust; and secondly, to prevent loosening and loss of the single pin 10.

[0048] In this embodiment, as Figure 1 As shown, the union structure is a union nut assembly 4, which includes a first union nut 41 and a retaining ring 42. The first union nut 41 has an internal thread for threaded connection with a threaded connector. A groove 121 is provided on the outer side wall of the second connector 12, and the retaining ring 42 is accommodated in the groove 121. One end of the first union nut 41 is fitted onto the outside of the second connector 12 and has a first stop edge 411. The inner diameter of the first stop edge 411 is smaller than the inner diameter of the first union nut 41 and smaller than the outer diameter of the retaining ring 42. The first stop edge 411 is axially limited to the side of the retaining ring 42 away from the end face of the second connector 12.

[0049] The retaining ring 42 can connect the first union nut 41 and the second connector 12, restrict the axial outward movement of the first union nut 41 to form a lock, and at the same time allow the first union nut 41 to rotate relative to the second connector 12, so as to facilitate the installation of the first union nut 41 and the threaded connector.

[0050] Furthermore, the union nut assembly 4 also includes a first sealing gasket 43, which is a flat gasket located inside the first union nut 41. One side of the first sealing gasket 43 abuts against the end face of the second connector 12, and the other side abuts against the end face of the threaded connector. After the threaded connector is installed, the first sealing gasket 43 fits tightly between the end face of the threaded connector and the end face of the second connector 12, providing a seal and preventing fluid leakage, eliminating the need for wrapping with Teflon tape.

[0051] Example 2

[0052] Reference Figure 3 The quick-install valve provided in this embodiment has a structure that is basically the same as that in Embodiment 1 above, and the similarities will not be repeated here. The main difference is that the union structure on the second connector 12 is used to connect to the PPR connector 30 at the inlet end. This embodiment uses a stop check valve as an example. Of course, this quick-install valve can also be a valve commonly used in waterworks, such as a ball valve, gate valve, pressure reducing valve, etc.

[0053] Specifically, from Figure 3As can be seen, the union structure is a PPR nut assembly 4′, which includes a second union nut 41′. The second union nut 41′ is used to connect with the PPR connector 30 at the inlet end. One end of the second union nut 41′ is threaded to the outer wall of the second connector 12, and the other end is provided with a second stop edge 412. One end of the PPR connector 30 is provided with a limiting boss 301. The inner diameter of the second stop edge 412 is smaller than the inner diameter of the second union nut 41′ and smaller than the outer diameter of the limiting boss 301. The limiting boss 301 is inserted into the second union nut 41′ and is axially limited to the inner side of the second stop edge 412.

[0054] During installation, first insert the small-diameter end of the PPR connector 30 into the second union nut 41', so that the limiting boss 301 of the PPR connector 30 is located inside the second union nut 41' and the limiting boss 301 abuts against the second stop edge 412. Then screw the second union nut 41' onto the second connector 12, thereby locking one end of the PPR connector 30 inside the second union nut 41'. At the same time, the PPR connector 30 can also rotate relative to the second union nut 41', so as to facilitate the installation of the PPR connector 30 with other pipelines.

[0055] Furthermore, such as Figure 3 As shown, the PPR nut assembly 4′ also includes a second sealing gasket 43′, which is disposed inside the second union nut 41′ and is sealed between the end face of the second connector 12 and the end face of the PPR connector 30. When the second union nut 41′ is tightened onto the second connector 12, the second sealing gasket 43′ fits tightly between the end face of the PPR connector 30 and the end face of the second connector 12, providing a seal and preventing fluid leakage, eliminating the need for additional Teflon tape.

[0056] Specifically, refer to Figure 3 In this embodiment, a protrusion 431 is provided on the side of the second sealing gasket 43′ near the second connector 12, and a groove 122 is provided on the side of the second connector 12 near the second sealing gasket 43′, with the protrusion 431 inserted into the groove 122. This arrangement can prevent the second sealing gasket 43′ from shifting and affecting the sealing effect when the PPR connector 30 rotates relative to the second union nut 41′.

[0057] In one optional embodiment, the second sealing gasket 43' may be provided with a plurality of protrusions 431 spaced apart along its circumference, with the grooves 122 and the protrusions 431 corresponding one-to-one. In another optional embodiment, the grooves 122 and the protrusions 431 may also be annular.

[0058] In another optional embodiment, a groove 122 is provided on the side of the second sealing gasket 43′ near the second connector 12, and a protrusion 431 is provided on the side of the second connector 12 near the second sealing gasket 43′, which can also achieve the above effect, and will not be described in detail here.

[0059] Therefore, the quick-install valve provided in this embodiment firstly, by setting the first connector 11 at one end of the valve as a socket structure 2, it can be plugged into a pipe 20 or another valve that is also equipped with a corresponding spigot structure 3. This facilitates quick disassembly, assembly, and maintenance between the valve and the pipe 20 or between valves, reducing installation difficulty and cost. Secondly, by connecting the second union nut 41' to the second connector 12 at the other end of the valve, the second union nut 41' can be matched with readily available water pipe fittings (PPR connector 30), resulting in better compatibility and greatly improving installation convenience.

[0060] Example 3

[0061] Reference Figure 4 The quick-connect valve provided in this embodiment has a structure that is basically the same as that in the first embodiment above. The similarities will not be repeated here. The main difference is that the first connector 11 on the valve body 1 is set as a socket structure 3. In actual installation, the pipe 20 or another valve connected to it is set as a socket structure 2. The effect achieved is the same as that achieved in the first embodiment, which will not be repeated here.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
