Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve structure for preventing leakage in a hydraulic pump station. Background Technology

[0002] A hydraulic pump station, also known as a hydraulic power source or hydraulic station, is an important component of a hydraulic system. Its main function is to supply oil according to the requirements of the drive device and control the direction, pressure, and flow of oil. The valves in the hydraulic pump station play a crucial role in the hydraulic system, as they are responsible for controlling the direction, pressure, and flow of oil, thereby ensuring the normal operation of the hydraulic pump station.

[0003] Referring to the patent application CN219639652U, a leak-proof hydraulic pump station valve structure is disclosed. By designing a maintenance mechanism, a threaded cover plate can be embedded into the interior of the internal threaded maintenance port and screwed in until the surface of the sealing gasket is pressed against the inner surface of the internal threaded maintenance port for sealing and installation, thus preventing leakage and strengthening the sealing installation of the valve body. Loosening the threaded slide body causes the end of the extrusion head to be pressed into the extrusion groove by the deformation of the extrusion spring. The threaded slide body is then screwed in to reinforce the tie rod and fix it to the extrusion head, so that the threaded cover plate is securely installed.

[0004] However, the above-mentioned technology involves reinforcing the device by embedding a threaded cover plate into the inspection port and then fixing the position of the extrusion head with a threaded slide body. This requires step-by-step operation. The existing device's sealing and disassembly maintenance procedures are relatively cumbersome, reducing maintenance efficiency and making it generally impractical. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof hydraulic pump station valve structure, comprising a main pipe body, and further comprising:

[0007] A control mechanism is located on the top surface of the main body to control the connectivity status of the main body.

[0008] The maintenance mechanism is located on the front side of the main pipe body for easy cleaning of debris inside the main pipe body. The maintenance mechanism includes maintenance pipes fixedly installed on the left and right ends of the front side of the main pipe body for easy cleaning of the main pipe body. A sealing cover is movably installed on the front side of the maintenance pipe. A threaded post is provided on the front side of the inner cavity of the sealing cover for fixing the position of the sealing cover. A sealing component is provided inside the sealing cover to prevent liquid from leaking from the maintenance pipe. A snap-fit ​​component is provided on the inner side of the sealing cover to improve the stability of the sealing cover.

[0009] Preferably, the sealing assembly includes a sealing gasket fixedly installed on the front side of the inner cavity of the sealing cap to prevent liquid from flowing out of the inspection tube, a rubber block fixedly installed on the rear side of the threaded post to reduce the liquid flowing into the inspection tube, the rear side of the sealing gasket being in close contact with the front side of the inspection tube, and the outer side of the rubber block being in close contact with the inner side of the inspection tube.

[0010] Preferably, the snap-fit ​​assembly includes movable grooves formed on the top and bottom surfaces of the inner side of the sealing cover. A snap-fit ​​block for improving the stability of the sealing cover is movably installed inside the movable groove. A connecting rod is fixedly installed on the side of the snap-fit ​​block away from the threaded post. A spring is movably installed on the outer side of the connecting rod. A connecting plate is movably hinged to one end of the connecting rod. A pressure plate is movably installed on the front side of the sealing cover. A limiting plate for restricting the movement trajectory of the pressure plate is fixedly installed on the front side of the sealing cover. Slots are formed on both the top and bottom surfaces of the inspection tube. Handles for convenient rotation of the sealing cover are fixedly installed on both the left and right sides of the sealing cover.

[0011] Preferably, the front side of the limiting plate movably passes through the rear side of the pressure plate and extends to the front side of the pressure plate; the front end of the connecting plate is movably hinged to the rear side of the pressure plate; the outer thread of the threaded column is installed inside the inspection tube; the end of the connecting rod away from the locking block movably passes through the interior of the movable groove and is movably hinged to one end of the connecting plate; the opposite sides of the locking block movably pass through the interior of the movable groove and extend into the interior of the locking groove; the opposite ends of the spring are fixedly installed on one side of the locking block; and the end of the spring away from the locking block is fixedly installed inside the movable groove.

[0012] Preferably, the control mechanism includes a connecting cylinder fixedly installed on the top surface of the main pipe, an adjusting rod movably installed on the top surface of the connecting cylinder, a handwheel for convenient rotation of the adjusting rod fixedly installed at the top end of the adjusting rod, a valve plate for controlling the fluid connectivity inside the main pipe being movably installed inside the main pipe, and a sealing ring for improving the sealing between the valve plate and the main pipe being fixedly installed on the outer side of the valve plate.

[0013] Preferably, the outer side of the sealing ring is tightly attached to the inner side of the main pipe body, and the bottom end of the adjusting rod movably passes through the top surface of the connecting cylinder and is fixedly installed on the top surface of the valve plate.

[0014] This invention provides a valve structure for preventing leakage in a hydraulic pump station. Compared with the prior art, it has the following advantages:

[0015] 1. The leak-proof hydraulic pump station valve structure features a threaded post and a locking block for easy installation and removal of the sealing cover. During installation, the threaded post is pressed tightly against the inside of the connecting plate, and then the sealing cover is rotated to thread the post onto the inspection pipe. Simultaneously, the inspection pipe forces the locking block into the movable groove. When the locking block aligns with the groove, the spring force causes it to insert into the groove, securing the sealing cover. For removal, pushing the pressure plate backward via the connecting plate pulls the connecting rod outward. The connecting rod then pulls the locking block out of the groove, releasing the sealing cover. Reversing the rotation of the sealing cover allows the threaded post to be removed from the inspection pipe for maintenance. The operation is simple and improves maintenance efficiency.

[0016] 2. The leak-proof hydraulic pump station valve structure improves the sealing performance of the device through the sealing ring. When in use, rotating the handwheel drives the adjusting rod to rotate, which in turn drives the valve plate to rotate to control the flow of liquid. When it is necessary to close the main body, rotating the handwheel in the opposite direction drives the valve plate to reset, so that the sealing ring is tightly attached to the inside of the main body, preventing liquid from flowing out when the valve plate is closed. It has good sealing performance and good practicality. Attached Figure Description

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.

[0023] See Figures 1-4 This utility model provides two technical solutions:

[0024] First embodiment: A leakage-preventing hydraulic pump station valve structure, including a main pipe body 1, and further comprising:

[0025] Control mechanism 2 is installed on the top surface of main body 1 to control the communication state of main body 1;

[0026] The maintenance mechanism 3 is located at the front of the main pipe body 1 to facilitate cleaning of debris inside the main pipe body 1. The maintenance mechanism 3 includes maintenance pipes 311 fixedly installed at both ends of the front of the main pipe body 1 for easy cleaning. A sealing cover 35 is movably installed on the front of the maintenance pipe 311. A threaded post 38 is located on the front side of the inner cavity of the sealing cover 35 to fix its position. A sealing assembly is provided inside the sealing cover 35 to prevent liquid leakage from the maintenance pipe 311. A snap-fit ​​assembly is provided inside the sealing cover 35 to improve its stability. The sealing assembly includes components fixedly installed on the front side of the inner cavity of the sealing cover 35 to prevent liquid from flowing out of the maintenance pipe 311. A rubber block 39 is fixedly installed on the rear side of the sealing gasket 310 and the threaded post 38 to reduce the flow of liquid into the inspection pipe 311. The rear side of the sealing gasket 310 is in close contact with the front side of the inspection pipe 311, and the outer side of the rubber block 39 is in close contact with the inner side of the inspection pipe 311. The snap-fit ​​assembly includes a movable groove 312 formed on the top and bottom surfaces of the inner side of the sealing cover 35. A snap-fit ​​block 313 is movably installed inside the movable groove 312 to improve the stability of the sealing cover 35, and the rear side of the snap-fit ​​block 313 is inclined. A connecting rod 36 is fixedly installed on the side of the snap-fit ​​block 313 away from the threaded post 38. A spring 37 is movably installed on the outer side of the connecting rod 36. One end of the connecting rod 36 is movably hinged to a spring 37. A connecting plate 31 is installed at an angle. A pressure plate 32 is movably installed on the front side of the sealing cover 35. A limiting plate 33 is fixedly installed on the front side of the sealing cover 35 to restrict the movement trajectory of the pressure plate 32. The top and bottom surfaces of the inspection tube 311 are provided with slots 314. Handles 34 for easy rotation of the sealing cover 35 are fixedly installed on both the left and right sides. The front side of the limiting plate 33 movably passes through the rear side of the pressure plate 32 and extends to the front side of the pressure plate 32. The front end of the connecting plate 31 is movably hinged to the rear side of the pressure plate 32. The outer thread of the threaded column 38 is installed inside the inspection tube 311. The end of the connecting rod 36 away from the locking block 313 movably passes through the movable groove 3. The internal part of the 12 is hinged to one end of the connecting plate 31. The opposite sides of the locking block 313 are movable through the interior of the movable groove 312 and extend into the interior of the locking groove 314. Pushing the pressure plate 32 backward through the connecting plate 31 can drive the connecting rod 36 to be pulled outward. Then the connecting rod 36 will drive the locking block 313 to be pulled out from the interior of the locking groove 314 to release the restriction on the sealing cover 35. The opposite end of the spring 37 is fixedly installed on one side of the locking block 313. The end of the spring 37 away from the locking block 313 is fixedly installed on the inside of the movable groove 312. The elastic force of the spring 37 can drive the locking block 313 to be inserted into the interior of the locking groove 314 to improve the stability of the sealing cover 35.

[0027] The threaded post 38 and the locking block 313 facilitate the installation and removal of the sealing cover 35. During installation, the threaded post 38 is pressed tightly against the inner side of the connecting plate 31, and then the sealing cover 35 is rotated to thread the threaded post 38 into the inspection tube 311. While rotating, the inspection tube 311 will push the locking block 313 into the interior of the movable groove 312. When the locking block 313 is aligned with the groove 314, the elastic force of the spring 37 will drive the locking block 313 to insert into the groove 314 and fix the position of the sealing cover 35. During removal, the pressure plate 32 is pushed backward, which will drive the connecting rod 36 to be pulled outward through the connecting plate 31. Then, the connecting rod 36 will drive the locking block 313 to be pulled out from the groove 314 to release the restriction on the sealing cover 35. Then, the sealing cover 35 is rotated in the opposite direction to remove the threaded post 38 from the inspection tube 311 for maintenance. The operation is simple and the maintenance efficiency is improved.

[0029] The sealing ring 25 can improve the sealing performance of the device. When in use, rotating the handwheel 21 will drive the adjusting rod 22 to rotate, and then the adjusting rod 22 will drive the valve plate 24 to rotate to control the flow of liquid. When it is necessary to close the main body 1, turn the handwheel 21 in the opposite direction to drive the valve plate 24 to reset so that the sealing ring 25 is tightly attached to the inside of the main body 1, preventing liquid from flowing out when the valve plate 24 is closed. It has good sealing performance and good practicality.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user installs the main pipe body 1 in a suitable position. When it is necessary to open the main pipe body 1, rotating the handwheel 21 drives the adjusting rod 22 to rotate. The adjusting rod 22 then drives the valve plate 24 to rotate to control the flow of liquid. When it is necessary to close the main pipe body 1, rotating the handwheel 21 in the opposite direction drives the valve plate 24 to reset, so that the sealing ring 25 is tightly attached to the inside of the main pipe body 1, preventing liquid from flowing out when the valve plate 24 is closed. When it is necessary to inspect the inside of the main pipe body 1, during disassembly, pushing the pressure plate 32 backward through the connecting plate 31 can drive the connecting rod 36 to be pulled outward. Then the connecting rod 36 will drive the locking block 3. 13. Pull out the seal cover 35 from the inside of the slot 314 to release the restriction. Then rotate the seal cover 35 in the opposite direction to remove the threaded post 38 from the inspection tube 311 for maintenance. After maintenance, press the threaded post 38 tightly against the inside of the connecting plate 31 and rotate the seal cover 35 to thread the threaded post 38 into the inspection tube 311. While rotating, the inspection tube 311 will push the block 313 into the inside of the movable groove 312. When the block 313 is aligned with the slot 314, the spring force of the spring 37 will drive the block 313 to insert into the inside of the slot 314 to fix the position of the seal cover 35.
