H742X Hydraulic Bottom Mud Discharge Valve
I. Introduction:
Hydraulic-operated tank bottom sludge discharge valves, also known as cover valves, are commonly used in the sedimentation tanks of urban waterworks and sewage treatment plants to discharge sludge at the tank bottom. The applicable medium for the sludge discharge valve is raw sewage, the temperature of the medium should generally be less than 50°C, and its working water depth is less than 10 meters. Sludge discharge valves are also used in water treatment plants to discharge sludge and wastewater from tanks. This type of valve has an angle-type structure, with an internal nylon-reinforced rubber diaphragm that allows for long-term use. It consists of a valve body, a hydraulic cylinder, a piston, a valve stem, and a valve disc. The hydraulic cylinder is a hydraulic tool that uses liquid as power, with the piston and valve stem serving as the switch. The valve plate can be opened in just one minute. This valve must be used with a manual directional valve or solenoid valve to remotely control the opening and closing of the sludge discharge valve. It features excellent sealing performance, flexible operation, easy maintenance, and a long service life of up to five years or more. By changing the fluid entering the upper or lower chamber of the hydraulic cylinder via the directional valve, the piston is driven to move, which in turn drives the valve plate to rise and fall, enabling the valve to open or close and achieve fluid on-off. The JM742X diaphragm-type tank bottom sludge discharge valve is used in various tanks of water companies or other enterprises to remove sediment and sludge.
