Sludge discharge valve for water treatment plants as sludge and waste water within the pool. The valve angle structure, strengthening the internal rubber diaphragm of nylon, for long-term use mud valve. Mud valve main parts Materials: cast iron, stainless steel and nylon to strengthen rubber. Meanwhile, the sludge valve main dimensions (flange dimensions comply with GB4216) are: H: 125,145,155,175,200,225,275,325,375 DN: 50,65,80,100,125,150,200,250,300 Structural characteristics of sludge discharge valve Also known as Mud valve cover valve, commonly used in urban water plants, sewage treatment plant sludge sedimentation with bottom discharge. Mud valve for medium to untreated sewage, the medium temperature should generally be less than 50 ℃, its work is less than 10 meters water depth. Mud valve structure generally have the following characteristics: Comes with valve cover screw, shallow water depth can be directly used when the operating handle; valve plate into a cone arch, built-oriented, open the operating force; screw and the sealing surface of tin bronze, corrosion and wear. Dual hoist with flashlight supporting the use of computer control. Diaphragm-type hydraulic, pneumatic valves are generally quick mud hydraulic valves and pneumatic roles Mud mud valve two. The main features of the valve is diaphragm drive mechanism with dual-chamber piston replacement, no sports wear, long life. Mud Valve products from the hydraulic cylinder and valve combination of roles, power driven hydraulic cylinder valve lift to valve open or closed channels, in order to achieve the fluid off. Hydraulic cylinder piston seal for the L-cups, the sealing performance and durability. Valve flap and valve seat for the soft seal, seal performance, no leakage. (Mud valve) using hydraulic, pneumatic angle valve or quick closure Mud reversing valve manually two centralized control, easy to operate. Mud valve principle and performance Diaphragm-type mud valve angle, commonly used in urban water plants, sewage treatment plant sludge sedimentation with bottom discharge. Mud valve for medium to untreated sewage, the medium temperature should generally be less than 50 ℃, its work is less than 10 meters water depth. Mud valve is usually installed in the water company or other types of pool next to the pool in order to rule out any sediment pool. The valve from the valve, hydraulic cylinder, piston, valve stem, valve flap formed cylinder liquid instruments. Liquid as the driving force, piston, valve stem as a switch. Open just a minute to open the valve plate, the valve must be fitted with a manual valve or solenoid valve for side can be remote controlled switching valve mud, sludge valve sealing performance, the switch flexible, easy maintenance, long service life, life of up to five years. Mud valve is a hydraulic pressure source by the implementing agency's role as cut-off valve valve. Usually installed in the sedimentation tank into the bottom row of the lateral wall, used to rule out the bottom sediment of the sediment and dirt. The hydraulic cylinder of the piston valve for the L-shaped cups, good sealing performance, durability, valve seal pair is also rubber seal, no leakage. Can also power two four-way reversing valve remote control. Easy to operate, safe and reliable.
