[0002] The knife-type gate valve has a knife-shaped oblique cut at the bottom of the flat valve plate, which has the function of cutting off the medium so that the valve is closed without being blocked by the medium. It is mainly used as a valve inside the pipeline where liquid flows to interrupt the liquid and has a wide range of uses.

[0003] According to application number 202321875463.3, it is related to a wear-resistant ceramic knife gate valve, including a tube body, a fixed sleeve is fixedly connected to the outer side of the tube body, a functional plate is arranged on the top of the functional plate, a connecting plate is fixedly connected to the top of the functional plate, a connecting rod is rotatably connected to the top of the connecting plate, a turntable is fixedly connected to the top of the connecting rod, a fixed column is fixedly connected to the top of the turntable, a fixing assembly is arranged on the top of the connecting plate, the fixing assembly is used to fix the turntable, a slide groove is opened inside the functional plate, and one end of the slide groove extends to the inside of the tube body.

[0004] The utility model aims to solve the problem that after the staff use and adjust the existing gate valve, the turntable is easily touched by mistake, which will cause the valve stem to rotate, resulting in the gate valve being accidentally opened and closed, affecting the staff's normal use of the gate valve, thereby reducing the practicability of the gate valve and increasing its limitations in use, which is not conducive to actual use.

[0005] However, the above solution still has certain shortcomings in actual use. After a long period of use, some impurities and dirt will adhere to the two surfaces of the general knife gate body. If they are not cleaned in time, these impurities and dirt will corrode the surface of the knife gate, thereby affecting the subsequent use of the knife gate. For this reason, we provide a multi-layer sealed knife gate valve. Utility Model Content

[0031] The top of the connecting rod 403 is fixedly connected to the bottom surface of the long plate 5, the bottom end of the connecting rod 403 is fixedly connected to a knife gate body 404, and the outer surface of the knife gate body 404 is fixedly connected to a rubber pad 405, and the outer surface of the connecting rod 403 is slidably connected to the upper surface of the valve body handle 1. The sliding connection between the connecting rod 403 and the valve body handle 1 can guide the connecting rod 403 and ensure the stability of the connecting rod 403 when sliding. At the same time, the knife gate body 404 can achieve sealing of the connecting pipe 2 to avoid water leakage. At the same time, the rubber pad 405 is made of rubber. The material of rubber can strengthen the sealing between the knife gate body 404 and the connecting pipe 2 and ensure the stability of the device during subsequent use.

[0032] The sealing assembly 4 also includes a fixed block 406, which is installed on the outer surface of the valve body handle 1. The outer surface of the fixed block 406 is slidably connected to a guide rod 407, and the top of the guide rod 407 is fixedly connected to the bottom surface of the long plate 5. By moving the long plate 5 up and down, and utilizing the sliding connection between the fixed block 406 and the guide rod 407, the movement of the long plate 5 can be guided, thereby ensuring the stability of the long plate 5 during movement.

[0033] A long plate 5 is arranged above the valve body handle 1, and a cleaning assembly 6 is installed on the outer surface of the valve body handle 1. The cleaning assembly 6 includes a mounting plate 601, and the mounting plate 601 is installed on the outer surface of the long plate 5. Two clip-on plates 602 of the same size are fixedly connected to the bottom surface of the mounting plate 601.

[0036] The long board 5 is driven up and down by the electric push rod 402, which can drive the installation plate 601 and the clamping plate 602. By utilizing the contact between the clamping joint 608 and the clamping plate 602, when the clamping plate 602 moves, the clamping joint 608 will be squeezed, so that the spring 607 will also be squeezed, and then the position of the slide bar 605 will retract, so that the clamping joint 608 is out of contact with the clamping plate 602. In many cases, the fixed plate 609 can be shaken, which can drive the cleaning brush 610 to shake, thereby achieving the cleaning work.
