Description

Technical Field

[0001] This utility model relates to the field of power plant valve technology, specifically a detachable power plant valve. Background Technology

[0002] "Power plant valves," also known as power plant-specific valves, are mainly used in pipelines of various systems in thermal power plants to cut off or connect pipeline media. Applicable media include non-corrosive media such as water and steam. Compared with other valve products, power plant valves are characterized by high temperature and high pressure, and a unique self-sealing design. The higher the pressure, the more reliable the seal. Due to their performance and technical characteristics and special operating conditions, these products have unique features that cannot be replaced by other products.

[0003] Power plant valves are widely used in various systems of power plants, including but not limited to water supply systems, circulating water systems, steam systems, liquid medium transportation systems, desulfurization and denitrification systems, etc. However, most of the existing power plant valves are connected to other pipelines by fixing them with farads and nuts. When the valve is connected to other pipelines for a long time, the nuts will rust. If the valve is damaged and needs to be replaced, the operator will need to spend a lot of time to replace it. Utility Model Content

[0004] To address the shortcomings of existing technologies, most power plant valves are currently connected to other pipelines by fixing them with a farrowing plate and a nut. However, after the valve has been connected to other pipelines for a long time, the nut may rust. If the valve is damaged and needs to be replaced, the operator will need to spend a lot of time to replace it. This utility model proposes a detachable power plant valve.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a detachable power station valve, including a gate valve body, the gate valve body including a horizontal valve tube, the top of the horizontal valve tube being connected to a vertical valve tube, the inner cavity of the vertical valve tube being threadedly connected to a threaded rod, the surface of the threaded rod being mounted with a handle, the surface of the horizontal valve tube being fixedly connected to a connecting seat, the number of connecting seats being two, the inner cavity of the connecting seat being movably connected to a connecting pipe, the inner cavity of the connecting pipe being provided with a groove, quick-release mechanisms being installed on both sides of the connecting seat, and a fixing mechanism being installed on one side of the quick-release mechanism;

[0006] The quick-release mechanism includes a movable groove and a fixed block. The movable groove is opened on the front and back sides of the inner cavity of the connecting seat. The fixed block is fixedly connected to the surface of the connecting seat. A rotating ring is rotatably connected inside the fixed block. The rotating ring is rotatably connected to the inside of the movable groove. A locking block is fixedly connected to the surface of the rotating ring. One side of the locking block is in close contact with the inside of the groove. A first handle is fixedly connected to the surface of the rotating ring.

[0007] Preferably, a rotating column is fixedly connected inside the fixing block, and the surface of the rotating column is rotatably connected to the inner cavity of the rotating ring.

[0008] Preferably, the fixing mechanism includes a recessed block, which is fixedly connected to both sides of the connecting seat, and sliding columns are movably connected to both sides of the inner cavity of the recessed block.

[0009] Preferably, one end of the sliding column is fixedly connected to an arc-shaped plate, the surface of which is in close contact with the surface of the first handle, and the other end of the sliding column is fixedly connected to a support plate.

[0010] Preferably, positioning blocks are fixedly connected to both sides of the concave block surface, the inner cavity of the positioning block is movably connected to the surface of the sliding column, and a tension spring is sleeved on the surface of the sliding column. One end of the tension spring is fixedly connected to one side of the positioning block, and the other end of the tension spring is fixedly connected to one side of the support plate.

[0011] Preferably, a second handle is fixedly connected to the surface of the support plate, and the second handle is elliptical in shape.

[0012] Preferably, a first sealing gasket is fixedly connected to both sides of the transverse valve pipe. The first sealing gasket is made of rubber. A second sealing gasket is fixedly connected to one side of the connecting pipe. The second sealing gasket is also made of rubber. One side of the first sealing gasket and one side of the second sealing gasket are tightly fitted together.

[0013] The advantages of this utility model are:

[0014] This invention allows for easy installation and disassembly by rotating the first handle, which in turn causes the rotating ring to rotate on the surface of the rotating column. The rotation of the ring causes the locking block to rotate, and as the locking block rotates, the groove disengages from the surface of the locking block. This solves the problem that in existing power plant valves, the connection with other pipelines is mostly fixed by a farrowing plate and a nut. When the valve is connected to other pipelines for a long time, the nut will rust. If the valve is damaged and needs to be replaced, the operator will have to spend a lot of time to replace it.

Detailed Implementation

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a detachable power station valve. (Refer to...) Figure 1-5 A detachable power station valve includes a gate valve body 1. The gate valve body 1 includes a horizontal valve tube 101. The top of the horizontal valve tube 101 is connected to a vertical valve tube 102. The inner cavity of the vertical valve tube 102 is threadedly connected to a threaded rod 103. A handle 104 is installed on the surface of the threaded rod 103. A connecting seat 105 is fixedly connected to the surface of the horizontal valve tube 101. There are two connecting seats 105. A connecting pipe 106 is movably connected to the inner cavity of the connecting seat 105. A groove 6 is opened in the inner cavity of the connecting pipe 106. A quick-release mechanism 2 is installed on both sides of the connecting seat 105. A fixing mechanism 3 is installed on one side of the quick-release mechanism 2.

[0025] The quick-release mechanism 2 includes a movable groove 201 and a fixing block 202. The movable groove 201 is formed on the front and back sides of the inner cavity of the connecting seat 105. The fixing block 202 is fixedly connected to the surface of the connecting seat 105. A rotating ring 204 is rotatably connected inside the fixing block 202. The rotating ring 204 is rotatably connected to the inside of the movable groove 201. A locking block 205 is fixedly connected to the surface of the rotating ring 204. One side of the locking block 205 is in close contact with the inside of the groove 6. A first handle 206 is fixedly connected to the surface of the rotating ring 204.

[0026] Reference Figure 3 and Figure 4 A rotating post 203 is fixedly connected inside the fixing block 202, and the surface of the rotating post 203 is rotatably connected to the inner cavity of the rotating ring 204. The rotating post 203 provides support for the rotating ring 204, making the rotating ring 204 more stable during rotation and preventing it from falling off.

[0027] Reference Figure 4 and Figure 5 The fixing mechanism 3 includes a recess 301, which is fixedly connected to both sides of the connecting seat 105. The recess 301 has sliding columns 303 movably connected to both sides of the inner cavity of the recess 301. The recess 301 supports the sliding columns 303, so that the sliding columns 303 remain stable after being pulled, and avoids the recess 301 from being unable to bear the load when the sliding columns 303 are pulled. The recess 303 also guides the (302) and makes the (302) more stable when moving, thereby better fixing the (206).

[0028] Reference Figure 5 One end of the sliding column 303 is fixedly connected to an arc-shaped plate 302, the surface of which is in close contact with the surface of the first handle 206. The other end of the sliding column 303 is fixedly connected to a support plate 306. The arc-shaped plate 302 can clamp and fix the first handle 206. When the first handle 206 rotates, the locking block 205 contacts the groove 6 to prevent the first handle 206 from rebounding. The support plate 306 supports the second handle 307, making it more stable when pulling the second handle 307.

[0029] Reference Figure 5Positioning blocks 304 are fixedly connected to both sides of the surface of the concave block 301. The inner cavity of the positioning block 304 is movably connected to the surface of the sliding column 303. A tension spring 305 is sleeved on the surface of the sliding column 303. One end of the tension spring 305 is fixedly connected to one side of the positioning block 304, and the other end of the tension spring 305 is fixedly connected to one side of the support plate 306. The positioning block 304 provides a fulcrum for fixing the position of the tension spring 305, preventing the tension spring 305 from being unable to be fixed. The tension spring 305 deforms when the second handle 307 is pulled, and quickly returns to its original shape when the second handle 307 is released, so that the arc plate 302 stably clamps the first handle 206, preventing the first handle 206 from falling out of the arc plate 302.

[0030] Reference Figure 4 and Figure 5 A second handle 307 is fixedly connected to the surface of the support plate 306. The second handle 307 is elliptical in shape. The second handle 307 provides a fulcrum for the operator. When it is necessary to remove the first handle 206, the operator only needs to hold the second handle 307 to move the arc plate 302, thereby facilitating the removal of the first handle 206 from the inside of the arc plate 302.

[0031] Reference Figure 2 and Figure 4 Both sides of the transverse valve pipe 101 are fixedly connected to a first sealing gasket 4, which is made of rubber. A second sealing gasket 5, also made of rubber, is fixedly connected to one side of the connecting pipe 106. The first sealing gasket 4 and the second sealing gasket 5 are tightly fitted together. Through the combined use of the first sealing gasket 4 and the second sealing gasket 5, they can be tightly fitted at the connection between the transverse valve pipe 101 and the connecting pipe 106, forming an effective sealing layer to prevent leakage at the connection. Furthermore, the first sealing gasket 4 and the second sealing gasket 5 can isolate moisture from direct contact with the metal pipe fittings, reducing metal corrosion caused by moisture erosion, thereby extending the service life of the pipe and its connecting parts.

[0032] Working principle: When the gate valve body 1 is damaged and needs to be replaced, first, grasp the second handle 307 and start pulling. The second handle 307 provides a fulcrum for the operator. Then, the movement of the second handle 307 drives the support plate 306. At this time, the tension spring 305 deforms and moves. The movement of the support plate 306 drives the sliding column 303 to move. After the sliding column 303 moves, it drives the arc plate 302 to move, causing the arc plate 302 to disengage from the surface of the first handle 206. The arc plate 302 clamps and fixes the first handle 206. At this time, release the second handle 307, and the locking block 205 quickly returns to its original shape. The change causes the arc plate 302 to return to its initial position. Once the arc plate 302 is no longer in contact with the first handle 206, the first handle 206 is pulled and rotated. The rotation of the first handle 206 causes the rotating ring 204 to rotate on the surface of the rotating column 203. The rotation of the rotating ring 204 causes the locking block 205 to rotate. As the locking block 205 rotates, the groove 6 is disengaged from the surface of the locking block 205. Then, the connecting pipe 106 is pulled by hand and dragged towards the outside of the connecting seat 105, which separates the transverse valve pipe 101 from the connecting pipe 106, thus facilitating the replacement of the gate valve body 1. If the gate valve body 1 needs to be installed, the above operation can be repeated.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
