The valve cover of the manual mud discharge valve comes with a screw, which can be operated directly with a handle when the water depth is shallow; The valve plate is conical and arched, with built-in guidance and low opening operation force; The screw and sealing surface are made of tin bronze, which is corrosion-resistant and wear-resistant. Can be used in conjunction with a dual-purpose flashlight for microcomputer control.

 

Structural characteristics of manual sludge discharge valve:

 

Diaphragm hydraulic and pneumatic quick opening mud valves generally have two types: hydraulic mud valves and pneumatic angle mud valves. The main feature of this valve is the use of a dual chamber diaphragm transmission mechanism instead of a piston type, with no motion wear. The sludge discharge valve is composed of a hydraulic cylinder and an angle type globe valve. The power inside the hydraulic cylinder drives the valve disc to rise and fall, opening or closing the valve body channel to achieve fluid flow. The piston seal of the hydraulic cylinder is an L-shaped cup. The valve disc and seat are soft sealed. The sludge discharge valve adopts hydraulic or pneumatic angle type quick opening sludge discharge valve or manual two position four-way reversing valve for centralized control.
