[0002] Power station valves, also known as specialized power station valves, are primarily used in the pipelines of various systems in thermal power plants to connect or disconnect media. Compared to other valves, these valves feature high-temperature, high-pressure, and unique self-sealing design. The higher the pressure, the more reliable the seal. These valves possess unique performance, technical characteristics, and specialized operating conditions, making them irreplaceable.

[0003] Chinese patent CN219263296U discloses a power station valve that is easy to disassemble, including a valve body, connecting pipes fixedly installed at both ends of the valve body, a flange fixedly installed at one end of the connecting pipe away from the valve body, a movable disc sleeved and installed on the outer side of the connecting pipe, a guide rail fixedly installed on the outer side of the connecting pipe, a slide groove provided on the inner side of the movable disc, and a positioning screw threaded on the outer side of the movable disc. When the power station valve is connected to the pipeline, the movable disc slides, and the outer arc-shaped support plate sleeves on the outer side of the connection. When disassembly is required, the bolts of the flange are first removed. After all are removed, the support plate is still sleeved on the connection, which supports the power station valve and prevents the valve body from falling during disassembly. Manual support is not required by the staff, making disassembly more convenient. This utility model adopts bolt connection, and tools need to be carried for disassembly, which makes installation and disassembly troublesome.

[0004] In summary, the existing technology has bolt-connected power station valves, which are complicated to install and disassemble and not portable enough. There are also safety hazards if the power station valves fall during disassembly. Utility Model Content

Embodiment

[0021] The following will further describe the present invention in detail with reference to the attached Figures 1-4 drawings.

[0022] Embodiment 1. Referring to Figures 1-4 , in this embodiment, in order to solve the problems that the power station valves with bolt connections in the prior art are complex in installation and disassembly and not portable enough, and there are potential safety hazards in case of dropping during the disassembly process of the power station valves. The present invention discloses a detachable power station valve, including a valve body control panel 1, a first valve pipe 2 and a second valve pipe 3. The first valve pipe 2 is perpendicular to the second valve pipe 3. There is a first valve 4 between the first valve pipe 2 and the valve body control panel 1. There are first sliding grooves 401 on both sides of the first valve 4. There is a fixing structure 5 adapted to the first sliding grooves 401. There is a sealing plate 402 on the front of the first valve 4. The inside of the sealing plate 402 is made of high-temperature resistant sealing material. The height of the first sliding groove 401 is consistent with the height of the sealing plate 402. There are pusher grooves 508 on both sides of the upper half of the first valve 4.

[0023] On the left and right sides of the second valve pipe 3, there are second sealing structures 6 respectively. The second sealing structure 6 includes a fixed block 601 and a folding module 602. Inside the left and right sides of the second valve pipe 3, there is an internal spiral 603. The outside of the position of the internal spiral 603 is welded to the second sealing structure 6. The fixed block 601 is on the left side of the folding module 602. The inner side of the folding module 602 is made of high-temperature resistant sealing material. It is connected to the pipeline through the internal spiral 603. In order to ensure the sealing performance of the connection, the second sealing structure 6 is used for secondary sealing. Since spiral connection is adopted, there is no problem of accidental injury caused by the dropping of the valve body.

[0024] The fixing structure 5 includes a fixed pusher 501, a push rod 502, a rubber plug 503, a plug sealing member 504, a spring assembly 505, a cavity 506 and a second chute 507. The left side of the lower half of the push rod 502 is connected to the rubber plug 503. The plug sealing member 504 is in the middle on the left side of the rubber plug 503. The rubber plug 503 and the push rod 502 are on the second chute 507. On the other side of the push rod 502 is the fixed pusher 501. The height of the fixed pusher 501 is adapted to the height of the pusher groove 508. Below the second chute 507 is the spring assembly 505. The plug sealing member 504 is arc-shaped, and its material is the same as that inside the sealing plate 402. The first valve 4 is mainly sealed twice by the main sealing plate 402 and the plug sealing member 504. By making the height of the fixed pusher 501 adapted to the height of the pusher groove 508, the stability of the plugging can be ensured when plugging. The second chute 507 drives the push rod 502, the plug sealing member 504 and the rubber plug 503 to move to the right, facilitating the opening of the valve.

[0025] Specific implementation principle: When using the present utility model, connect the second valve pipe 3 with the pipeline to be connected. Pull the fixed block 601 to move to both sides to expand the folding module 602. Place the valve body control panel 1 on the first valve 4. Slide the fixing structure 5 upward through the first chute 401 to the middle of the first valve 4. Move the push rod 502 inward along the second chute 507, and insert the fixed pusher 501 into the pusher groove 508 to complete the assembly of the power station valve. Similarly, pull out the fixed pusher 501 from the pusher groove 508, move the push rod 502 outward along the second chute 507, and press down the fixed pusher 501 to make the fixing structure 5 slide downward through the first chute 401 to complete the disassembly of the valve.

[0026] The above are all the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited hereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model shall be covered within the protection scope of the present utility model.
