Description

Filter gate valve Technical Field The utility model relates to the technical field of gate valves, in particular to a filter gate valve. Background The gate valve is a shutter, the moving direction of the shutter is vertical to the direction of fluid, the gate valve can only be fully opened and fully closed, and can not be regulated and throttled, and in order to avoid the problem of blockage, the existing gate valve is generally provided with a filtering structure thereon, so that impurities in water flowing through the gate valve are filtered by the filtering structure. For example, the prior patent (publication number: CN 220168623U) discloses a filtering gate valve, after the water flow passes through the filter box, the water flow flows into the valve body, the water flow is filtered through the first filter plate and the second filter plate respectively, larger sundries are filtered through the first filter holes, smaller sundries are filtered through the second filter holes, and then the filtering efficiency is improved. However, the filter gate valve has the defects that although the filter gate valve can filter water flow through the first filter plate and the second filter plate respectively, larger sundries are filtered through the first filter hole, smaller sundries are filtered through the second filter hole, and further the filtering efficiency is improved, the impact force generated by the water flow instantaneously when the valve is opened is overlarge, so that the filter screen is easy to wash and deform, the connection between the filter screen and the valve is easy to loose, and the damage of the filter screen is accelerated. For this purpose, we have devised a filter gate valve to solve the above-mentioned problems. Disclosure of utility model The present utility model is directed to a filter gate valve, which solves the above-mentioned problems. In order to solve the technical problems, the filtering gate valve provided by the utility model comprises a gate valve body, wherein one side of the gate valve body is provided with a filter box, two sides of the filter box are fixedly connected with connecting pipes in an inserted mode, one of the connecting pipes is connected with the gate valve body, a fixing piece is fixedly installed in the filter box, a guide opening is formed in the fixing piece, a filter screen is slidably arranged in the filter box, two sliding blocks are symmetrically arranged in the fixing piece in a sliding mode, a rotating piece is rotatably arranged between the sliding blocks and the filter screen, and buffer pieces are arranged on one sides of the two sliding blocks opposite to each other. Further, the number of the diversion openings is two, and the two diversion openings are symmetrically arranged in the fixing piece. Further, the limiting groove is formed in the center of one side of the fixing piece, the two sliding blocks are symmetrically and slidably inserted into the limiting groove, the buffer piece comprises a spring and a damping cylinder, two ends of the spring and the damping cylinder are fixedly installed between the inner wall of the limiting groove and the sliding blocks respectively, and the spring is movably sleeved on the damping cylinder. Further, one side of the sliding block is fixedly provided with a mounting seat, the center of one side of the filter screen is fixedly provided with a fixing seat, and two ends of the rotating piece are respectively arranged in the mounting seat and the fixing seat in a rotating mode. Further, a first pin shaft is arranged in the mounting seat, a second pin shaft is arranged in the fixing seat, and two ends of the rotating piece are respectively and rotatably sleeved on the first pin shaft and the second pin shaft. Further, two support seats are fixedly installed between the rotating pieces, telescopic rods are rotatably arranged between the support seats, third pin shafts are arranged in the support seats, and two ends of each telescopic rod are rotatably sleeved on the two third pin shafts respectively. Compared with the prior art, the utility model has the beneficial effects that when water flow flushes on the filter screen, the filter screen can slide in the filter box at the moment, in the process, the rotating piece can rotate and push the two sliding blocks to move away from each other in the limit groove, meanwhile, the spring can be compressed and absorb impact force, after the water flow is stable, the spring can rebound slowly by matching with the damping cylinder, the buffer effect of the filter screen can be realized, the deformation of the filter screen is avoided, and the service life of the filter screen is prolonged. Compared with the prior art, the telescopic rod has the beneficial effects that when the included angle between the two rotating parts is increased, the telescopic end of the telescopic rod is lengthened, the telescopic rod is enabled to rotate in a micro-amplitude manner, the r
