Inflatable dome valve main performance characteristics: 1. Opening and closing flexible, spool no flushing; dome valve in the switching process, the spool and a special rubber seal to maintain a gap of 0.8 ~ 1.5mm, spool action Non-contact ring, running resistance, flexible rotation, reliable, long service life of the sealing ring; When the valve is open, the mouth of the whole circulation without blocking, to avoid the material on the spool of direct erosion. 2. Tight seal, excellent performance; dome valve seal with a special inflatable rubber seal, good sealing. When the dome valve is closed, the rubber ring inflates, expands and tightly wraps around the spherical valve core to form a very reliable seal ring that is tightly sealed to effectively shut off the flow of material in the pipe. 3. Material selection, science and technology; valve core is the core of the dome valve, according to the use of different working conditions with different wear-resistant materials, the product has a wear-resistant, erosion resistance and other characteristics; valve core smooth and hard surface, The valve core and rubber seal in close contact with the seal to achieve the best configuration. 4 automatic control, reliable operation; dome valve pneumatic actuators using fully enclosed rotary push rod-type straight cylinder drive, rotary output, reliable performance, output torque, to meet the working conditions in harsh conditions.
Inflatable 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 spool and the seal to reduce wear and tear. Domed valve pneumatic actuator for the whole closed rotary push rod 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 and expands tightly against the spherical dome valve core, creating a very reliable seal band that prevents the flow of material from the pipe. When the dome valve is open, the rubber seal is vented and the dome valve spool opens, at which point the valve opens.
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 to ensure a reliable seal. Rubber seals made of special materials, 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 medium: gas, liquid, semi-fluid and solid powder.
