Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a PE pipe valve that is easy to disassemble and assemble. Background Technology

[0002] PE pipe valves are control components specifically designed for polyethylene pipe systems. They are mainly used to regulate, cut off, or divert fluids (such as water, gas, etc.) within the pipes.

[0003] In existing PE pipe valve technology, the installation and disassembly process is complex and cumbersome. During installation, a variety of complex operations are required to ensure the sealing and stability after installation. Disassembly also requires many reverse steps, which not only consumes a lot of time and manpower, but also easily affects the installation quality and valve stability due to improper operation, causing great inconvenience to actual use.

[0004] Therefore, there is a need for a PE pipe valve that is easy to install and disassemble, in order to solve the problem of the complex and cumbersome installation and disassembly process of PE pipe valves in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a PE pipe valve that is easy to install and disassemble, so as to solve the problem of complex and cumbersome installation and disassembly process of PE pipe valves in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PE pipe valve that is easy to disassemble and assemble, comprising a valve body and connecting rings respectively installed on the inlet and outlet ends of the valve body, wherein each of the two connecting rings is provided with an installation mechanism; The installation mechanism includes a circular shell coaxially mounted on one side of the connecting ring, a rotating ring coaxially rotatably mounted inside the circular shell, three circumferentially distributed guide grooves on one side of the circular shell, a through hole coaxially penetrating the side of the circular shell, a movable block movably mounted in the guide groove, three arc-shaped rods rotatably mounted between the rotating ring and the three movable blocks, a worm gear coaxially mounted on the rotating ring, a worm rotatably mounted inside the circular shell and meshing with the worm gear, an arc-shaped clamping block mounted on one side of the movable block, and an operating rod coaxially mounted on one end of the worm and rotatably extending out of the circular shell. The circular shell is equipped with an anti-accidental contact component.

[0007] It should be noted in the solution that the anti-accidental touch component includes a fixed block installed on the outer surface of the round shell, a vertical column installed on the top surface of the fixed block, a stop plate that is movably installed on the top of the vertical column via a threaded coaxial connection, a protective shell that is rotatably installed on the outer surface of the round shell, a rotating plate that is rotatably installed on the top surface of the protective shell, and a cross groove that penetrates through the top surface of the rotating plate.

[0008] It is worth noting that both connecting rings have coaxial slots on the side near the corresponding circular shell, and rubber rings and sealing rings are installed inside the slots.

[0009] Furthermore, it should be noted that each of the arc-shaped clamping blocks has an anti-slip pad installed on its inner surface, and the inner surface of the anti-slip pad has several anti-slip patterns.

[0010] In a preferred embodiment, both operating levers are located inside the corresponding protective housing, and the cross groove cooperates with the corresponding vertical column and stop plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By rotating the stop plate to release the lock on the rotating plate, the rotation of the rotating plate causes the protective shell to rotate, exposing the operating rod. Rotating the operating rod drives the worm gear to rotate, causing the rotating ring to move through the arc-shaped rod and move the moving block. This allows the three arc-shaped clamping blocks to clamp and fix the external pipe through the anti-slip pad. The protective shell prevents the operating rod from being accidentally touched. The cooperation of the rubber ring and the sealing ring improves the sealing performance of the external pipe in the slot, while increasing the friction at the junction of the external pipe and the slot, thus improving the stability of the external pipe in the slot. This effectively avoids the complicated and cumbersome process of installing and disassembling PE pipe valves. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a valve body 1 and connecting rings 2 respectively installed on the inlet and outlet ends of the valve body 1, and each of the two connecting rings 2 is provided with an installation mechanism 3; The mounting mechanism 3 includes a circular shell 31 coaxially mounted on one side of the connecting ring 2, a rotating ring 32 coaxially rotatably mounted inside the circular shell 31, three circumferentially distributed guide grooves 33 on one side of the circular shell 31, a through hole 34 coaxially penetrating the side of the circular shell 31, a movable block 35 movably mounted in the guide groove 33, three arc-shaped rods 36 rotatably mounted between the rotating ring 32 and the three movable blocks 35, a worm gear 37 coaxially mounted on the rotating ring 32, a worm 38 rotatably mounted inside the circular shell 31 and meshing with the worm gear 37, an arc-shaped clamping block 39 mounted on one side of the movable block 35, and an operating rod 310 coaxially mounted on one end of the worm 38 and rotatably extending out of the circular shell 31. An anti-accidental contact component 4 is provided on the circular shell 31.

[0016] Specifically, after the external pipe passes through the through hole 34, the operating lever 310 is rotated to drive the worm gear 38 to rotate, which in turn drives the worm wheel 37 to drive the rotating ring 32 to rotate. The rotating ring 32 drives the moving block 35 to slide in the guide groove 33 through the arc rod 36. The three moving blocks 35 simultaneously drive the three arc clamping blocks 39 to move towards the external pipe to clamp and fix the external pipe, so as to facilitate the installation of the valve body 1. Similarly, the valve body 1 can be disassembled by reversing the operation.

[0017] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the anti-accidental touch component 4 includes a fixing block 41 installed on the outer surface of the circular shell 31, a vertical column 42 installed on the top surface of the fixing block 41, a stop plate 43 movably installed on the top of the vertical column 42 via a threaded coaxial connection, a protective shell 44 rotatably installed on the outer surface of the circular shell 31, a rotating plate 45 rotatably installed on the top surface of the protective shell 44, and a cross groove 46 penetrating the top surface of the rotating plate 45.

[0018] Specifically, the operating lever 310 is protected by the protective shell 44 to prevent accidental contact. By rotating the stop plate 43 from a horizontal to a vertical position, the lock on the rotating plate 45 can be released. Then, rotating the rotating plate 45 will cause the protective shell 44 to rotate, exposing the operating lever 310 so that it can be rotated when installing or removing the valve body 1.

[0019] Further as Figure 2 As shown, it is worth noting that both connecting rings 2 have slots 5 coaxially formed on the side of the corresponding circular shell 31, and rubber rings 6 and sealing rings 7 are installed inside the slots 5.

[0020] Specifically, the external pipe passes through the through hole 34 and is inserted into the slot 5. With the cooperation of the rubber ring 6 and the sealing ring 7, the sealing performance of the external pipe in the slot 5 is improved, and the friction at the junction of the external pipe and the slot 5 is increased, so as to improve the stability of the external pipe in the slot 5.

[0021] Further as Figure 3 As shown, it is worth noting that each arc-shaped clamping block 39 has an anti-slip pad 8 installed on its inner surface, and the inner surface of the anti-slip pad 8 has several anti-slip patterns.

[0022] Specifically, the arc-shaped clamping block 39 drives the anti-slip pad 8 to clamp and fix the external pipe, thereby improving the clamping and fixing effect of the external pipe.

[0023] Further as Figure 3 and Figure 4 As shown, it is worth noting that both operating levers 310 are located inside the corresponding protective housing 44, and the cross groove 46 cooperates with the corresponding vertical column 42 and stop plate 43.

[0024] Specifically, both operating levers 310 are located inside the corresponding protective housings 44. The protective housings 44 prevent the operating levers 310 from being accidentally touched. The cross grooves 46 cooperate with the corresponding vertical posts 42 and stop plates 43 to lock the protective housings 44 or allow the protective housings 44 to rotate so that the operating levers 310 are exposed.

[0025] In summary: During installation, the external pipe is first inserted into the slot 5 through the through hole 34. The rubber ring 6 and the sealing ring 7 work together to improve the sealing performance of the external pipe in the slot 5 and increase the friction at the junction of the external pipe and the slot 5, thus improving the stability of the external pipe in the slot 5. Next, the stop plate 43 is rotated from a horizontal to a vertical position. At this time, the vertical column 42 and the stop plate 43 form a cross shape that matches the cross groove 46, thereby releasing the lock on the rotating plate 45. Rotating the rotating plate 45 causes the protective shell 44 to rotate, exposing the operating rod 310. Then, rotating the operating rod 310 drives the worm gear 38 to rotate, which in turn drives the worm wheel 37 to rotate the rotating ring 32. The arc rod 36 pulls the moving block 35 in the guide groove 33. The sliding mechanism moves the three moving blocks 35 simultaneously, driving the three arc-shaped clamping blocks 39 towards the external pipe. With the cooperation of the anti-slip pad 8, the three arc-shaped clamping blocks 39 clamp and fix the external pipe. Then, the protective shell 44 and the rotating plate 45 are rotated in the opposite direction, so that the vertical column 42 and the stop plate 43 are inserted into the cross groove 46. Then, the stop plate 43 is rotated in the opposite direction to lock the rotating plate 45, preventing the operating rod 310 from being accidentally touched and improving the stability of the valve body 1 after installation. After the two external pipes are installed and fixed to the inlet and outlet ends of the valve body 1 respectively, the installation operation of the valve is completed. Similarly, the valve can be removed by performing the above operations in reverse. The operation is simple and effectively avoids the complicated and cumbersome installation and disassembly process of PE pipe valves.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
