[0031] 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 protection scope of the present utility model.

[0032] Please see Figures 1-5 The present invention provides a technical solution: a vertical multi-functional hydraulic slide gate valve, comprising a housing 10, a support frame 20, a hydraulic cylinder 30, a moving rod 301, a pressure plate 302, a blocking plate 303, a connecting plate 304, an airbag 1 305, a pipe 306, an airbag 2 307, a slot 40, a cavity 50, an airbag 3 501, a spring 502, a moving block 503, and an air pipe 504;

[0033] This vertical multi-functional hydraulic slide gate valve improves the valve's sealing performance. The specific implementation method is as follows:

[0034] A support frame 20 is symmetrically fixedly connected to the surface of the outer shell 10, and a hydraulic cylinder 30 is connected to the surface of the support frame 20. A sealing mechanism is provided inside the outer shell 10, comprising: a groove 40 embedded in the surface of the outer shell 10; a pressure plate 302 fixedly connected to the end of the output shaft of the hydraulic cylinder 30; a moving rod 301 fixedly connected to the bottom of the pressure plate 302; a blocking plate 303 connected to the end of the moving rod 301; a connecting plate 304 symmetrically installed on the surface of the support frame 20; an airbag 305 installed on the surface of the connecting plate 304; a pipe 306 connected to the surface of the airbag 305; an airbag 307 installed inside the groove 40; a pipe 306 connected to the surface of the airbag 307; a cavity 50 embedded in the bottom of the outer shell 10; an airbag 501 symmetrically installed inside the cavity 50; an air pipe 504 connected to the surface of the airbag 50; and a spring 502 installed at the bottom of the cavity 50. A shift block 503 is installed at the end of the spring 502. The bottom of the pressure plate 302 is in contact with the surface of the airbag 305, and both ends of the pressure plate 302 are inserted into the surface of the support frame 20. The support frame 20 and the pressure plate 302 are slidably connected. The blocking plate 303 is positioned corresponding to the slot 40, and the slot 40 and the blocking plate 303 are slidably connected. The support frame 20 and the blocking plate 303 are slidably connected, and a shift rod 301 is slidably connected to the support frame 20. The end of the cavity 50 is positioned corresponding to the position of the slot 40. The bottom of the blocking plate 303 is in contact with the surface of the moving block 503. The moving block 503 is slidably connected to the outer shell 10. The moving block 503 is positioned at the end of the cavity 50. The bottom of the moving block 503 is in contact with the surface of the airbag 501. The airbag 501 is slidably connected to the outer shell 10. The air tube 504 is inserted into the outer shell 10. The end of the air tube 504 is positioned inside the slot 40.

[0035] Start the hydraulic cylinder 30, causing the end of the hydraulic cylinder 30 to drive the pressure plate 302 to move upward, causing the pressure plate 302 to drive the moving rod 301 to move upward, causing the moving rod 301 to drive the blocking plate 303 to move upward, and the blocking plate 303 to move upward inside the outer shell 10, causing the blocking plate 303 to move out from inside the empty groove 40. At this time, the material can pass through the hole in the empty groove 40. At this time, the pressure of the pressure plate 302 on the first airbag 305 disappears, causing the first airbag 305 to rebound. At this time, the gas inside the second airbag 307 flows back into the first airbag 305, causing the first airbag 305 to inflate. At this time, the second airbag 307 contracts. At the same time, the pressure of the blocking plate 303 on the moving block 503 disappears, causing the spring 502 to unwind. At this time, the spring 502 pushes the moving block 503 to move upward, causing the pressure of the bottom of the moving block 503 on the third airbag 501 to disappear, causing the third airbag 501 to absorb outside air and expand through the air inlet pipe.

[0036] Start the hydraulic cylinder 30, which pushes the pressure plate 302 downward, causing the pressure plate 302 to move the moving rod 301 downward. The moving rod 301 then moves the blocking plate 303 downward, causing the blocking plate 303 to move downward inside the outer shell 10. The blocking plate 303 moves to the empty slot 40, blocking the empty slot 40. At the same time, the pressure plate 302 squeezes the first airbag 305 downward, causing the first airbag 305 to contract. The gas inside the first airbag 305 enters the second airbag 307 through the pipe 306, causing the second airbag 307 to inflate. This causes the outer side of the second airbag 307 to contact the gap between the blocking plate 303 and the outer shell 10, thus blocking the gap between them.

[0037] At the same time, when the end of the blocking plate 303 contacts the moving block 503, it pushes the moving block 503 to move downward, causing the moving block 503 to push the spring 502 to contract. At this time, the end of the moving block 503 squeezes the airbag 3 501 downward, causing the object inside the airbag 3 501 to enter the air tube 504, and causing the gas to be ejected through the end of the air tube 504. At the same time, a one-way valve is provided on the surface of the air tube 504, so that the air tube 504 blows off the residual material at the bottom of the blocking plate 303, preventing the material from getting stuck between the blocking plate 303 and the outer shell 10.

[0038] Working principle: When using this vertical multi-functional hydraulic slide gate valve, airbag 1 305, pipeline 306, airbag 2 307 and airbag 3 501 are set to improve the valve's sealing performance and increase its overall practicality.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
