What is the structure and working principle of the sludge discharge valve

structural characteristics and working principle of sludge discharge valve

sludge discharge valve is used in water treatment plants as a discharge tank for sludge and wastewater. The valve is of angular structure with nylon reinforced rubber diaphragm inside, which can be used as a sludge discharge valve for a long time

the main parts of the sludge discharge valve are made of cast iron, stainless steel and nylon reinforced rubber. At the same time, the main boundary dimensions of the sludge discharge valve (flange connection 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

the structural characteristics of the sludge discharge valve

the sludge discharge valve is also known as the cover valve, which is generally used for sludge discharge at the bottom of the sedimentation tank of urban water plants and sewage treatment plants. The applicable medium of the sludge discharge valve is primary sewage. The temperature of the medium should generally be less than 50 ℃, and its working water depth should be less than 10 meters

generally, the sludge discharge valve has the following structural features that greatly reduce the cost of modified special materials:

the valve cover has its own screw, which can be directly operated by the handle when the water depth is shallow; The valve plate is in conical arch shape, with its own guide, and the opening operation force is small; The screw and sealing surface are made of tin bronze, which is corrosion-resistant and wear-resistant. It can be matched with the manual electric hoist for microcomputer control

diaphragm hydraulic and pneumatic quick opening sludge discharge valves generally include hydraulic sludge discharge valve and pneumatic angle sludge discharge valve. The main feature of the valve is that the double chamber diaphragm transmission mechanism is used to replace the piston type, with no movement wear and long service life. The sludge discharge valve product is composed of a hydraulic cylinder and an angle stop valve. The power in the hydraulic cylinder drives the valve flap to rise and fall, so that the channel of the valve body can be opened or closed to achieve fluid on-off

the piston seal of the hydraulic cylinder is an L-shaped cup, which has good sealing performance and is durable. The valve disc and valve seat are soft sealed, with good sealing performance and no leakage. (sludge discharge valve) adopts hydraulic and pneumatic angle quick opening sludge discharge valve or manual two position four-way reversing valve for centralized control, which is easy to operate

working principle and performance of sludge discharge valve

angle diaphragm sludge discharge also provides various equipment information valves after using computer technology. It is generally used to discharge sludge at the bottom of sedimentation tanks in urban water plants and sewage treatment plants. The applicable medium of the sludge discharge valve is primary sewage. The temperature of the medium should generally be less than 50 ℃, and its working water depth should be less than 10 meters. The sludge discharge valve is generally installed next to and in the water supply company or other pools, so as to remove the sediment in the pool at any time. The valve is composed of valve body, hydraulic cylinder, piston, valve rod and valve disc. The hydraulic cylinder is a liquid tool. Liquid as power, piston and valve rod as switch. The valve plate can be opened after only one minute. The valve must be equipped with a manual Square change valve or a solenoid valve, which can remotely control the switch of the sludge discharge valve. The sludge discharge valve has the characteristics of strong sealing performance, flexible switch, convenient maintenance and long service life, and its service life can reach more than five years

sludge discharge valve is a kind of angle stop valve with hydraulic source as 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 piston of the hydraulic cylinder of the valve is an L-shaped leather cup, which has good sealing performance and is durable. The valve sealing pair is also a rubber seal. There is no leakage in the mechanical performance testing equipment such as the electronic universal testing machine, the hydraulic universal testing machine, the horizontal tensile testing machine and the fatigue testing machine. The remote control can also be realized through the electric two position four-way reversing solenoid valve. Easy to operate, safe and reliable
