Description

Anti-blocking structure of large-caliber adjusting cut-off valve Technical Field The utility model relates to the technical field of valves, in particular to an anti-blocking structure of a large-caliber adjusting and cutting-off valve. Background The large-caliber regulating cut-off valve is widely applied to industries such as petroleum, chemical industry, natural gas, water treatment, electric power and the like, is used for controlling the cut-off and the cut-on of high-flow fluid, and is an indispensable fluid control device in industrial production. The problem that the use efficiency is affected by internal blockage caused by the entering of particle diameter foreign matters in a medium is easy to occur in the conventional large-caliber regulating cut-off valve, so that an anti-blocking structure of the large-caliber regulating cut-off valve is provided. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides the anti-blocking structure of the large-caliber adjusting cut-off valve, so that a set of anti-blocking mechanism is provided for the large-caliber adjusting cut-off valve body, media entering the large-caliber adjusting cut-off valve body can be filtered, the condition that the blocking hidden danger is caused by the entry of foreign matters with particle size into the large-caliber adjusting cut-off valve body is effectively avoided, accumulated dirt in filtration can be rapidly discharged under the condition of partial disassembly, and the long-term use stability of the cut-off valve is greatly improved. The technical scheme adopted by the utility model for solving the technical problems is that the anti-blocking structure of the large-caliber adjusting and cutting-off valve comprises an anti-blocking and pollution discharging mechanism arranged at the feeding end of a large-caliber adjusting and cutting-off valve body; The anti-blocking pollution discharge mechanism comprises a pollutant collecting box, side sealing plates and a lower cover plate, wherein the two sides of the pollutant collecting box are respectively provided with a feed inlet and a discharge outlet, the side sealing plates are provided with two groups and are arranged on the two sides in the pollutant collecting box, and the side sealing plates are respectively covered on the feed inlet and the discharge outlet.
