Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a double buffer valve. Background Technology

[0002] A double-buffered valve is a type of valve that uses a double-buffered structure to effectively reduce vibration and water hammer caused by fluid impact and pressure changes during the opening and closing of the valve. For example, in large water supply or chemical fluid transportation pipelines, when the valve is suddenly closed, the water flow will still impact the valve and pipeline due to inertia, thus generating a water hammer effect and damaging the valve.

[0003] A double-buffered valve is generally composed of a valve body, a valve, a buffer chamber, and a spring valve. In use, the liquid first enters through the buffer chamber for initial buffering, and then the liquid impacts the spring valve. After the impacted spring valve opens, the liquid enters the valve and then passes through the valve and is transported through the pipeline.

[0004] Traditional double-buffered valves typically combine the buffer valve and spring valve with the control valve. While this design can effectively reduce the overall size of the valve, the spring valve and other components are quite delicate and prone to leakage after a period of use. Furthermore, the integrated design makes it difficult to disassemble, repair, or replace the valve, requiring a complete replacement and resulting in a lower cost-effectiveness. Utility Model Content

[0005] The purpose of this utility model is to provide a double buffer valve to solve the problem that the existing double buffer valves are inconvenient to use because their integrated design makes it difficult to replace and repair the internal spring valves.

[0006] This utility model provides the following technical solution: a double buffer valve, including a valve body, an outlet fixedly connected to one end of the valve body, and a double buffer valve provided at the end of the valve body away from the outlet via a replacement component, an inlet fixedly connected to the end of the double buffer valve away from the valve body, and the replacement component including a first connecting end fixedly connected to the end of the valve body near the double buffer valve, and a second connecting end provided on the side of the first connecting end away from the valve body.

[0007] The above technical solution facilitates subsequent positioning and assembly by utilizing the fit between the first and second connecting ends.

[0008] As a preferred embodiment of the above technical solution, a ring is fixedly connected to the middle of the side of the first connecting end near the second connecting end, and a sealing ring is fixedly connected to the end of the ring away from the first connecting end.

[0009] The above technical solution utilizes a ring and a sealing ring to seal the contact area between the first connecting end and the second connecting end.

[0010] As a preferred embodiment of the above technical solution, a connecting block is provided on the outer side of the sealing ring, and one end of the connecting block near the second connecting end is fixedly connected to the second connecting end, and a retaining ring is fixedly connected to the other end of the connecting block away from the second connecting end, and the other end of the retaining ring away from the connecting block is inserted into the first connecting end.

[0011] The above technical solution utilizes connecting blocks and retaining rings to initially lock and restrict the first and second connecting ends.

[0012] As a preferred embodiment of the above technical solution, the two sets of connecting blocks and retaining rings are mirrored, and the retaining rings are set to an arc shape.

[0013] The above technical solution involves mirroring the connecting block and the retaining ring, and setting the retaining ring to an arc shape, which facilitates the retaining ring to be inserted into the first connecting end for locking by rotation.

[0014] As a preferred embodiment of the above technical solution, a locking block is fixedly connected to the inner side of both ends of the first connecting end, and a first spring is fixedly connected to the end of the locking block away from the first connecting end, and the end of the first spring away from the locking block is inserted into the second connecting end.

[0015] Through the above technical solution, the elastic potential energy of the locking block can be used to push the first spring out and insert it into the second connecting end for secondary locking.

[0016] As a preferred embodiment of the above technical solution, push blocks are inserted into the inner sides of both ends of the second connecting end, and push plates are fixedly connected to both ends of the push blocks. The end of the push plate away from the push block is inserted into the second connecting end, and a second spring is fixedly connected to the middle of the push plate. The end of the second spring away from the push plate is fixedly connected to the second connecting end.

[0017] The above technical solution allows the pusher block to move the first spring, thereby pushing the first spring out of the second connecting end.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This type of double buffer valve allows for quick disassembly and replacement via the first connection end. When internal parts of the double buffer valve are damaged, it can reduce maintenance or replacement costs, thereby improving the cost-effectiveness of the double buffer valve.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a double buffer valve, including a valve body 1, an outlet 11 fixedly connected to one end of the valve body 1, and a double buffer valve 12 provided at the end of the valve body 1 away from the outlet 11 via a replacement component, an inlet 13 fixedly connected to the end of the double buffer valve 12 away from the valve body 1, and the replacement component includes a first connecting end 2 fixedly connected to the end of the valve body 1 near the double buffer valve 12, and a second connecting end 21 provided on the side of the first connecting end 2 away from the valve body 1. The fit between the first connecting end 2 and the second connecting end 21 facilitates the subsequent assembly of parts.

[0028] like Figure 3 As shown, a ring 3 is fixedly connected to the middle of the side of the first connecting end 2 near the second connecting end 21, and a sealing ring 31 is fixedly connected to the end of the ring 3 away from the first connecting end 2. The ring 3 and the sealing ring 31 are used to facilitate the sealing treatment of the joint between the first connecting end 2 and the second connecting end 21.

[0029] like Figure 4As shown, a connecting block 4 is provided on the outer side of the sealing ring 31, and the end of the connecting block 4 near the second connecting end 21 is fixedly connected to the second connecting end 21. A retaining ring 41 is fixedly connected to the end of the connecting block 4 away from the second connecting end 21, and the end of the retaining ring 41 away from the connecting block 4 is inserted into the first connecting end 2. The connecting block 4 drives the retaining ring 41 to rotate, so that the retaining ring 41 can be inserted into the first connecting end 2 for initial positioning.

[0030] like Figure 4 As shown, the two sets of connecting blocks 4 and retaining rings 41 are mirror images of each other, and the retaining rings 41 are set in an arc shape. Setting the retaining rings 41 in an arc shape makes it easier to insert them into the first connecting end 2 for locking.

[0031] like Figure 5 As shown, the inner sides of both ends of the first connecting end 2 are fixedly connected with a locking block 5, and the end of the locking block 5 away from the first connecting end 2 is fixedly connected with a first spring 51. The end of the first spring 51 away from the locking block 5 is inserted into the second connecting end 21. The elastic potential energy of the locking block 5 can push the first spring 51 to pop out.

[0032] like Figure 5 As shown, push blocks 6 are inserted into the inner sides of both ends of the second connecting end 21, and push plates 61 are fixedly connected to both ends of the push blocks 6. The end of the push plate 61 away from the push blocks 6 is inserted into the second connecting end 21, and a second spring 62 is fixedly connected to the middle of the push plate 61. The end of the second spring 62 away from the push plate 61 is fixedly connected to the second connecting end 21. Pushing the push blocks 6 to compress the second spring 62 with the assistance of the push plate 61 can push the first spring 51 out of the second connecting end 21.

[0033] Working principle: When installing and using the double buffer valve, first bring the second connecting end 21 of the double buffer valve 12 closer to the first connecting end 2. During this approach, the second connecting end 21 adheres to the sealing ring 31. Then, the second connecting end 21, through the connecting block 4, allows the retaining ring 41 to be inserted into both ends of the first connecting end 2. After the retaining ring 41 is inserted, the second connecting end 21 compresses the first spring 51. The first spring 51, after being compressed, is inserted into the first connecting end 2, compressing the retaining block 5. Then, rotate the second connecting end 21. After the second connecting end 21 rotates, it pushes the retaining ring 41 to rotate through the connecting block 4, so that the retaining ring 41 is fully inserted into the first connecting end 2 for initial locking. After the retaining ring 41 is inserted, the retaining block 5 utilizes its elastic potential... The first spring 51 can be pushed to pop out and insert into the second connecting end 21 for secondary locking and fixing, thereby realizing the assembly and use of the valve body 1 and the double buffer valve 12. When the internal parts of the double buffer valve 12 are damaged and need to be replaced or repaired, the push block 6 is pushed. After the push block 6 is pushed, it drives the push plate 61 to move and compress the second spring 62. Then the push block 6 moves and squeezes the first spring 51. After the first spring 51 is squeezed, it is inserted into the first connecting end 2 and compresses the locking block 5. Then the first spring 51 is pushed out of the second connecting end 21. At this time, the second connecting end 21 is rotated, and the locking ring 41 is rotated through the connecting block 4. After the locking ring 41 is pulled out of the first connecting end 2, the first connecting end 2 and the second connecting end 21 can be separated.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
