Gate valve with good flashboard anti-sticking effect

Abstract

The invention discloses a gate valve with a good flashboard anti-sticking effect, and belongs to the field of gate valves. According to the scheme, when fluid impacts a flashboard body, an impact expansion mechanism absorbs impact force to serve as power to drive a magnetic insulation bag body to expand, the impact force influence is relieved, the flashboard body is not prone to being damaged, and a vibration falling mechanism is extruded to drive the flashboard body to vibrate; the radial scraping mechanism shakes off substances and the like adhered to the flashboard body after fluid impact on the surface of the flashboard body, so that the substances are not easy to adhere to the flashboard body, interference of the substances to the flashboard body during working is reduced, meanwhile, the radial scraping mechanism scrapes off the adhered substances on the flashboard body through the cleaning adhesive tape, comprehensive cleaning is achieved, working of the flashboard body is facilitated, and the service life of the flashboard body is prolonged. And a magnetic suction blowing mechanism extrudes air in an elastic expansion air bag to be sprayed out, blows off the flashboard body and cleans residual substances on a rubber strip, substance residues are reduced, cleaning is more sufficient and comprehensive, the cleaning efficiency is improved, the influence of substance adhesion on use of the flashboard body and the gate valve body is avoided, and the use effect of the gate valve body is effectively enhanced.

Description

technical field [0001] The invention relates to the field of gate valves, and more particularly, to a gate valve with good anti-sticking effect of gate plates. Background technique [0002] The gate valve is an opening and closing gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. It is mainly used to control air, water, steam, various corrosion. With the continuous development of industrial production, the use of gate valves is becoming wider and wider. [0003] During the working process of the gate valve, the movement of the gate plate realizes the flow of fluid, but after the gate plate stops the fluid, the fluid impinges on the gate plate, which is easy to make some fluid substances adhere to the surface, which accumulates too much, which is easy to damage the gate plate. Use causes influence, thereby reducing the use effect of the gate v...
