Embodiment 1

[0035]A valve and pipeline connection system with simple and effective sealing, including a valve body 1, a fixing mechanism 4 is installed on the lower left and right sides of the valve body 1, and the fixing mechanism 4 includes an external connecting pipe 401, a rubber pad 402, and a first vertical block 403 , ear plate 404, fixing bolt 405, card slot 406, first vertical bar 407, second vertical block 408, second threaded rod 409, third vertical bar 410, handle 411, first cross bar 412, curved bar 413, Through groove 414 and moving ball 415, the right end of the left external connecting pipe 401 is closely attached to the left end of the rubber pad 402, the right end of the rubber pad 402 is closely attached to the lower left end of the valve body 1, and the rubber pad 402 is connected to the external connecting pipe 401 and the valve body. The connection between 1 is sealed, the rubber pad 402 is made of fluorine rubber material, the upper and lower ends of the right side o...

Embodiment 2

[0037] As an option, see figure 1 , 4 And 5, a new type of linkage valve, an anti-leakage mechanism 5 is installed in the middle of the bottom of the valve body 1, and the anti-leakage mechanism 5 includes a first valve flap 501, a rubber block 502, a second valve flap 503, a fixed block 504, a triangular block 505, The second cross bar 506, the compression spring 507, the cross block 508, the second vertical bar 509 and the groove 510, the middle inner wall of the first valve flap 501 is connected to the lower outer wall of the first threaded rod 2 through a sealed bearing, and the first screw thread The rod 2 drives the first valve flap 501 to move up and down, the left and right ends of the first valve flap 501 are fixedly connected to the inner side of the rubber block 502, and the outer sides of the rubber block 502 are fixedly connected to the inner side of the second valve flap 503. The outer walls of the first valve disc 501, the rubber block 502 and the second valve ...

Embodiment 3

[0040] An application of a valve and pipeline connection system with simple and effective sealing. When using this new type of linkage valve, firstly, the external connecting pipes 401 on both sides are manually attached to the inlet and outlet on the left and right sides of the valve body 1 through rubber pads 402. At the position, the ear plates 404 on both sides are fixed on the external pipe 401 by fixing bolts 405 so that the first vertical block 403 is fixed on the external pipe 401, and the turning handle 411 drives the second threaded rod 409 to rotate in the third vertical rod 410 through the bearing. Make the second vertical block 408 drive the first vertical bar 407 to move inwardly on the outer wall of the second cross bar 412, and the first vertical bar 407 moves inwardly in the draw-in slot 406 on the first vertical block 403 to the outer connecting pipe 401 to the right The force makes the connection between the external connecting pipe 401 and the valve body 1 t...

Abstract

The invention discloses a valve and pipeline connecting system simple and effective in sealing. The system involves a valve body, fixing mechanisms are arranged on the left side and the right side ofthe lower portion of the valve body, the right end of an external connecting pipe on the left side is tightly attached to the left end of a rubber pad, and the right end of the rubber pad is tightly attached to the left end of the lower portion of the valve body. According to a novel linkage valve, first vertical rods move towards an inner side in clamping grooves in first vertical blocks to applyforce towards the right side to the external connecting pipe, so that the connection between the external connecting pipe and the valve body is tight, the gas-liquid leakage is prevented, and the phenomenon that due to the fact that an existing linkage valve is affected by external factors for a long time, the joint of the existing linkage valve and the external connecting pipe is loosened, and then the gas-liquid leakage is caused is avoided; and second valve clacks on the two sides can be returned to be tightly attached to the inner wall of the valve body through elasticity of compression springs, so that the liquid-gas leakage caused by gaps existing between the valve body and the valve clacks is prevented, and the problem that due to long-time use of the valve clacks of an existing linkage valve, gaps exist between the valve clacks and the valve body, and then the gas-liquid leakage is caused is solved.

Description

technical field [0001] The invention relates to the technical field of linkage valves, in particular to a valve and pipeline connection system with simple and effective sealing. Background technique [0002] Linkage valves are widely used in long-distance natural gas pipelines. They have the advantages of stable transmission, easy control, and no need for power supplies. At the same time, it is equipped with a manual mechanism as a backup. However, due to the long-term influence of external factors, the existing linkage valve will loosen at the connection with the external connecting pipe, causing the problem of gas-liquid leakage. At the same time, there is a problem with the existing linkage valve. Due to long-term use, there will be a gap between the valve disc and the valve body, which will cause gas and liquid leakage. Contents of the invention [0003] The purpose of the present invention is to provide a valve and pipeline connection system with simple and effective...
