The mud discharge valve is also called the cover valve, which is mainly used in the sewage treatment system.
The sludge discharge valve is used in water treatment plants to discharge the sludge and waste water in the pool. The valve is an angle structure with a nylon reinforced rubber diaphragm inside, which can be used for long-term use as a mud discharge valve.
The main parts materials of mud discharge valve are: cast iron, stainless steel and nylon reinforced rubber. At the same time, the main dimensions of the mud 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
Structural characteristics of mud discharge valve
The sludge discharge valve, also known as the cover valve, is generally used to discharge sludge from the bottom of the sedimentation tank of urban water plants and sewage treatment plants. The applicable medium of the sludge discharge valve is raw sewage, the temperature of the medium should generally be less than 50°C, and the working water depth should be less than 10 meters.
The mud discharge valve generally has the following structural features:
The valve cover has its own screw rod, which can be directly operated by the handle when the water depth is shallow; the valve plate is conical arched, with its own guide, and the opening operation force is small; the screw rod and sealing surface are made of tin bronze, which is corrosion-resistant and wear-resistant. It can be used together with flashlight dual-purpose hoist for microcomputer control.
Diaphragm hydraulic and pneumatic quick opening mud valves generally have two types: hydraulic mud valve and pneumatic angle type mud valve. The main feature of the valve is that it adopts a double-chamber diaphragm transmission mechanism instead of a piston type, which has no movement wear and long service life. The mud discharge valve product is composed of a hydraulic cylinder and an angle globe valve. The power in the hydraulic cylinder drives the valve up and down to open or close the passage of the valve body 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 the valve seat are soft seals, with good sealing performance and no leakage. (Mud discharge valve) adopts hydraulic and pneumatic angle-type quick-opening mud discharge valve or manual two-position four-way reversing valve for centralized control, which is easy to operate.
Working principle and performance of mud discharge valve
Angle diaphragm type sludge discharge valve is generally used to discharge sludge from the bottom of sedimentation tanks in urban water plants and sewage treatment plants. The applicable medium of the sludge discharge valve is raw sewage, the temperature of the medium should generally be less than 50°C, and the working water depth should be less than 10 meters. The mud discharge valve is generally installed next to or in the water company or other types of pools, so as to remove the sediment in the pool at any time. The valve is composed of a valve body, a hydraulic cylinder, a piston, a valve stem, and a valve disc, and the hydraulic cylinder is a liquid tool. The liquid is used as power, and the piston and valve stem are used as switches. It only takes one minute to open the valve plate. This valve must be equipped with a manual reversing valve or a solenoid valve to remotely control the switch of the mud discharge valve. The mud discharge valve has strong sealing performance, flexible switching, convenient maintenance, and long service life. The life span can reach more than five years.
The mud discharge valve is a kind of angle-type globe valve with hydraulic source as the actuator. It is usually installed in rows on the outer wall of the bottom of the sedimentation tank to remove the mud, sand and dirt deposited at the bottom of the tank. The piston of the valve hydraulic cylinder is an L-shaped leather cup, which has good sealing performance and is durable. The valve sealing pair is also a rubber seal without leakage. Remote control can also be realized through the electric two-position four-way reversing solenoid valve. Easy to operate, safe and reliable.
