Pressure equalizing and bleeding valve for top feeding system, there are two structures: one is straight stroke, hydraulic drive, cast steel structure, soft and hard seal, the other is angular stroke, hydraulic drive, full welding structure, model lp745y.
In general, the valve is sealed by medium pressure. Under special circumstances, the valve is sealed by heavy hammer or hydraulic cylinder
he valve can be used for opening and closing the power distribution winch or the hydraulic transmissionLS744Y/X-
Suitable for blast furnace top riser top and dust removal system, used as gas release
Main technical features of non-counterweight roof relief valve. Adopting four-bar linkage mechanism, canceling counterweight,compact structure, light weight, safety and economy
The valve can be opened and closed quickly, so that the sealing surface is protected from erosion, and the starting force is small and the service life is long.
The seal surface of valve cover is sealed with cemented carbide and rubber, and the seal is tight, reliable and zero leakage.
A small amount of wear on the sealing surface is compensated by the butterfly spring, which is reliable, efficient and longevity.5 Hydraulic drive, integration of hydraulic cylinder and valve body
