Fluid sluice valve opened and closed rapidly

Abstract

A brake valve comprises a valve body, a valve rod, a flashboard, a handle, a handle seat, a liquid inlet, a liquid outlet and a seal ring. The valve rod in the brake valve is a light valve rod. The valve rod and the valve body are respectively provided with a pressing pin and a pressing plate cooperated with the pressing pin. An operation handle can lead the pressing pin to pass through a throughhole on the pressing plate and enter into a locking position and the liquid inlet is sealed and closed through the valve rod driving the flashboard. The invention can operate reversely. The flashboardcan move backwards quickly to open the liquid outlet and is adjusted to the position of the handle seat, thus being able to still ensure the flashboard to realize pressing seal on the liquid inlet after the seal ring is worn; thereby reaching the goals of preventing leakage and prolonging the service life. The brake valve has the advantages of simple structure, convenient operation, reliable sealing and long service life. The brake valve can realize fast liquid discharge and brake breaking of feculent slurry with large flow. Compared with a brake valve with same flow and caliber in the market, the price can be reduced by 50 percent. The brake valve has a bigger using value and excellent market prospect.

Description

technical field [0001] The present invention relates to a liquid dispensing device, in particular to a gate valve among valves. Background technique [0002] There are about 3,000 enterprises producing valves in my country. The various types of valves produced, such as gate valves, ball valves, butterfly valves, etc., are various in variety, complete in function, and relatively perfect in various performances. They are widely used in industrial and agricultural production, urban heating, water supply, gas, and Pipeline, petrochemical and many other aspects have played an important role. But when these valves are used in some special occasions (such as large-flow biogas liquid tanks, mud, sewage pipes, aquaculture dilute feed and other turbid liquids), the original design performance cannot be achieved. Due to the poor working environment in these occasions, it is not suitable to use expensive precision valves. Traditional gate valves generally adopt the principle of screw dr...

AI Technical Summary

Problems solved by technology

Due to the poor working environment in these occasions, it is not suitable to use expensive precision valves. Traditional gate valves generally adopt the principle of screw drive, and the opening and closing movements are slow, which is not only time-consuming and laborious, but also prone to blockage, lax closure and leakage Phenomenon, can not meet the requirements of rapid discharge of turbid slurry and gate break
