Description

Elastic compression type anti-blocking flashboard structure Technical Field The utility model relates to the technical field of flat gate valves, in particular to an elastic compression type anti-blocking flashboard structure. Background The flat gate valve is a valve which is opened and closed by a gate plate and is widely applied to various fluid pipeline systems. The working principle is that when the flashboard is completely opened, fluid can smoothly pass through the flashboard, and when the flashboard is completely closed, the fluid is completely blocked. According to the utility model, the spring telescopic structure arranged in the valve body can provide certain elastic force, so that the flat plate flashboard can be better attached to the clean flashboard seat, the sealing performance of the flat plate flashboard is enhanced, meanwhile, certain boosting force is provided for resetting and cleaning, and the spiral surface cleaning sheet can guide a medium to form rotary flow, so that the flat plate flashboard seat, the surface of the valve plate and the inner surface of a concave groove of the flashboard can be stripped and cleaned.
