Description

Technical Field

[0001] This application relates to the field of valve technology, and in particular to an aluminum backrest valve for pipelines. Background Technology

[0002] In a valve with a backrest, the "backrest" usually refers to the valve seat, a key component that supports the valve core in the fully closed position and provides a seal. Based on the different characteristics of the valve seat, valves can be classified as rigid-backed valves or flexible-backed valves.

[0003] Traditional backrest valves are not good at buffering impact forces, and prolonged use will affect the sealing effect. Utility Model Content

[0004] This application provides an aluminum backrest valve for pipelines to solve the problem that it is inconvenient to buffer and dampen impact forces, and that long-term use will affect the sealing effect.

[0005] This application provides an aluminum backrest valve for pipelines, including a valve seat. An A rubber backrest is fixedly disposed on the inner wall of the valve seat. A resin backrest is fixedly disposed on the inner wall of the A rubber backrest. A B rubber backrest is fixedly disposed on the inner wall of the resin backrest. An aluminum backrest is fixedly disposed on the inner wall of the B rubber backrest. An A flange is fixedly disposed on one side of the valve seat, and a B flange is fixedly disposed on the other side of the valve seat. A connecting pipe is fixedly disposed on one side of both the A and B flanges. A silicone ring is fitted onto the surface of the connecting pipe, and a rubber ring is fixedly fitted onto the surface of the silicone ring.

[0006] Preferably, a positioning tube is fixedly provided on the top surface of the valve seat, a valve stem is rotatably provided inside the positioning tube, a rotating wheel is fixedly provided on the top of the valve stem, and a valve plate is fixedly provided on the bottom of the valve stem, the valve stem being used to drive the valve plate to rotate.

[0007] Preferably, the top surfaces of the A rubber backrest, resin backrest, B rubber backrest, and aluminum backrest are all provided with rotating holes, and the valve stem is rotatably disposed inside the rotating hole, which facilitates the rotation of the valve stem.

[0008] Preferably, both flange A and flange B have connection holes on their surfaces, and a connecting stud is threaded through the internal thread of the connection hole. A nut is threaded to one end of the connecting stud, and the nut is used to fix the connecting stud.

[0009] Preferably, one side of flange A is threadedly connected to an inlet pipe via a connecting stud, and the other side of flange B is fixedly installed with an outlet pipe, which facilitates the discharge of the medium.

[0010] Preferably, there are four sets of connecting studs and nuts, which are arranged in a circular array to fix the flange and the pipe.

[0011] Preferably, the surfaces of the inlet pipe and the outlet pipe are provided with four sets of limiting screw holes in a ring array, which are used to fix the connecting studs.

[0012] Beneficial effects:

[0013] Considering the difficulty in buffering impact forces and the potential impact on sealing performance over time, rubber backrests A, resin backrests, and rubber backrests B buffer the impact forces on the valve seat and valve plate. Aluminum backrests are lightweight, have moderate hardness, and good elasticity, providing good sealing while offering support.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-4 The illustrated aluminum backrest valve for pipelines includes a valve seat 1, an A rubber backrest 2 fixedly mounted on the inner wall of the valve seat 1, a resin backrest 3 fixedly mounted on the inner wall of the A rubber backrest 2, a B rubber backrest 4 fixedly mounted on the inner wall of the resin backrest 3, and an aluminum backrest 10 fixedly mounted on the inner wall of the B rubber backrest 4. An A flange 11 is fixedly mounted on one side of the valve seat 1, and a B flange 12 is fixedly mounted on the other side of the valve seat 1. A connecting pipe 13 is fixedly mounted on one side of both the A flange 11 and the B flange 12. A silicone ring 14 is sleeved on the surface of the connecting pipe 13, and a rubber ring 15 is fixedly sleeved on the surface of the silicone ring 14.

[0030] Among them, rubber backrest 2, resin backrest 3 and rubber backrest 4 buffer the impact force on valve seat 1 and valve plate 9, while aluminum backrest 10 is lighter and has moderate hardness and good elasticity, providing good sealing while supporting.

[0031] When connecting the valve to the external pipeline, silicone ring 14 and rubber ring 15 are respectively put on the connecting pipe 13. When connecting flange A 11 to inlet pipe 18 and flange B 12 to outlet pipe 17, silicone ring 14 and rubber ring 15 seal the connection. Silicone ring 14 is more flexible and will fill the surrounding gaps when under pressure, providing a better sealing effect when connected to the pipeline.

[0032] A positioning tube 5 is fixedly installed on the top surface of the valve seat 1. A valve stem 7 is rotatably installed inside the positioning tube 5. A rotating wheel 8 is fixedly installed on the top of the valve stem 7. A valve plate 9 is fixedly installed on the bottom of the valve stem 7.

[0033] Rotating the wheel 8 causes the valve stem 7 to rotate, which in turn causes the valve plate 9 to rotate.

[0034] The top surfaces of rubber backrest 2, resin backrest 3, rubber backrest 4, and aluminum backrest 10 are all provided with rotating holes, and the valve stem 7 is rotatably disposed inside the rotating holes.

[0035] The rotating hole allows the valve stem 7 to pass through and rotate.

[0036] Both flange A 11 and flange B 12 have connection holes on their surfaces. The internal threads of the connection holes are threaded through the connection studs 16, and one end of the connection studs 16 is threaded with a nut 6.

[0037] The connecting stud 16 connects flange A 11 and inlet pipe 18, and nut 6 is used for locking.

[0038] One side of flange A 11 is threadedly connected to an inlet pipe 18 via a connecting stud 16, and the other side of flange B 12 is fixedly installed with an outlet pipe 17.

[0039] Flange 11 (A) is used to connect to inlet pipe 18, and flange 12 (B) is used to connect to outlet pipe 17.

[0040] There are four sets of connecting studs 16 and nuts 6, and the four sets of connecting studs 16 and nuts 6 are arranged in a ring array.

[0041] Nut 6 is used to lock the connecting stud 16.

[0042] The surfaces of the inlet pipe 18 and the outlet pipe 17 are provided with four sets of limiting screw holes in a ring array.

[0043] The limiting screw hole is used to fix the connecting stud 16.

[0044] Working principle: When this type of aluminum backrest valve for pipelines is used, rubber backrest 2 (A), resin backrest 3, and rubber backrest 4 (B) buffer the impact force on valve seat 1 and valve plate 9. The aluminum backrest 10 is lightweight and has moderate hardness and good elasticity, providing good sealing while supporting the valve.

[0045] When connecting the valve to the external pipeline, silicone ring 14 and rubber ring 15 are respectively put on the connecting pipe 13. When connecting flange A 11 to inlet pipe 18 and flange B 12 to outlet pipe 17, silicone ring 14 and rubber ring 15 seal the connection. Silicone ring 14 is more flexible and will fill the surrounding gaps when under pressure, providing a better sealing effect when connected to the pipeline.

[0046] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
