product description
diaphragm hydraulic/pneumatic quick-opening sludge discharge valve, also known as cover valve, is often used to discharge sludge at the bottom of sedimentation tanks in urban water plants and sewage treatment plants. the suitable medium for the sludge discharge valve is primary sewage, the temperature of the medium should generally be less than 50 °c, and the working water depth is less than 10 meters. sludge valves are also used in water treatment plants to discharge sludge and wastewater from pools. the mud valve is of angular structure, and the inner nylon reinforced rubber diaphragm can be used for a long time.
diaphragm hydraulic/pneumatic quick-opening sludge discharge valve is a kind of angle-type cut-off valve with hydraulic source or pneumatic source as the actuator. it is usually installed in rows on the outer wall of the bottom of the sedimentation tank to remove the sediment and dirt at the bottom of the tank. the valve is divided into two chambers by nylon reinforced rubber diaphragm, connected to hydraulic or pneumatic source, and controlled by electric or manual two-position four-way reversing valve to realize rapid sludge discharge. the valve replaces the piston with the diaphragm, has no motion friction, is more suitable for granular media such as mud, and greatly improves the service life of the valve.
