Inflatable dome valve structure features

Inflatable dome valve structure features:

Dome valve is a new type of fast closing valve, which uses the most advanced gas-sealed structure, the valve opening and closing of the valve core and inflatable seals without contact between the seals made of special formula rubber can be widely Applied to the sealing of powdered material, it is a key component in pneumatic conveying system and widely used in electric power, metallurgy, chemical industry, food, pharmacy and other fields. Valve core ring without contact with the operation, the running resistance of small, long life;

Dome valve spool according to the different use of different materials, the surface of the different hardening treatment, the use of smooth and hard surface of the valve core to ensure good contact with the rubber seal in close contact to ensure a reliable seal. Rubber ring made of special rubber, with high temperature, wear resistance, anti-aging characteristics, long service life. When the valve is opened, the material mouth full circulation unobstructed. The valve is suitable for gas, liquid, semi-fluid and solid powder and other substances. Pneumatic actuators using linear or fan-shaped cylinder closed-loop drive, the output torque, reliable performance, to meet the conditions of poor working conditions.

Dome valve works:

Dome valve spool is a spherical dome, dome valve in the switching process, the spool and the rubber seal to maintain a gap of about 2mm, the valve core and the rubber seal can be non-contact movement, the purpose is So that there is no friction between the valve core and the rubber seal to reduce wear and tear. Dome valve pneumatic actuator for the entire sealed linear or fan-shaped cylinder, direct drive dome valve rotation, which effectively prevents dust from entering the cause of wear and tear, leakage and so on. When the dome valve is closed, the rubber ring inflates, expands and presses tightly against the spherical dome valve core, creating a very reliable seal ring that prevents the flow of material from the pipe.

Dome valve spool according to the different use of different materials, the surface of the different hardening treatment, the use of smooth and hard surface of the valve core to ensure good contact with the rubber seal in close contact to ensure a reliable seal. Rubber ring made of special rubber, with high temperature, corrosion resistance, wear resistance, anti-aging characteristics, long service life. When the valve is opened, the material mouth full circulation unobstructed. The valve is suitable for gas, liquid, semi-fluid and solid powder and other substances.

Dome valve Note:

Rubber ring inflation pressure should be guaranteed at 0.40-0.60MPa and higher than the delivery pressure of 0.15MPa, cylinder working pressure 0.45-0.65MPa, the use of clean, dry, oil-free compressed air.
