Pneumatic dome valve, wear-resistant dome valve Pneumatic dome valve (spherical air lock valve) is a new type of quick-closing valve. It adopts the most advanced air-sealing structure in the world, and the valve opening and closing valve core is air-sealed. There is no contact between rings, and the sealing ring is made of special rubber. It can be widely used for sealing powdery materials. It is a key component in the pneumatic conveying system and is widely used in metallurgy, electric power, chemical industry, food, pharmaceutical and other fields.
The valve core has no contact with the sealing ring during operation, has low resistance and has a long service life
It adopts an inflatable sealing ring and has good sealing performance
The pneumatic actuator adopts a linear cylinder or sector cylinder for fully enclosed drive , with large output torque and reliable performance, it can meet the needs of working under harsh industrial and mining conditions.

Working principle:
The valve core of the pneumatic dome valve is a spherical dome. During the switching process of the dome valve, the gap maintained between the valve core and the sealing ring allows the valve core and sealing ring to move in a non-contact manner. The purpose is to ensure that the valve core There is no friction between it and the sealing ring, reducing friction. The pneumatic actuator of the dome valve is a fully sealed linear cylinder or sector cylinder, which directly drives the movement of the dome valve, effectively preventing dust from entering and causing wear, leakage and other phenomena. When the dome valve is in the closed state, the rubber seal is inflated, expanded, and pressed tightly against the spherical dome valve core, thus forming a very reliable sealing ring that prevents the flow of materials in the pipeline.
The dome valve core is made of different materials according to different use occasions, and the surface adopts different hardening treatments. The hard surface of the valve core can ensure good and close contact with the sealing ring to ensure reliable sealing. The rubber sealing ring is made of special rubber, which has the characteristics of high temperature resistance, corrosion resistance, wear resistance, aging resistance and long service life. When the valve is opened, the material port is fully flowing without obstruction. The valve is suitable for gas, liquid, semi-fluid and solid powder and other substances.
Notes:
The inflation pressure of the rubber sealing ring should be guaranteed to be at ., and the maximum output pressure should be ., and the cylinder working pressure should be . Use clean, dry, oil-free compressed air.
Important points for installation and use:
Please read this manual carefully before installation and check the valve model, diameter and technical parameters.
.It is strictly prohibited to install the valve welding flange to avoid damaging the valve sealing ring. The installation size of the reserved valve for the pipeline should be appropriate, and gaskets should be added on both sides of the flange.
3. The center of the two pipes and the diameter center of the valve should be kept coaxial, the flange surface should be flat, and no large deflection of the flange surface is allowed to ensure the clamping and normal operation of the valve. The tightening bolts should be Be even and symmetrical.
.The valve has been adjusted and dynamically tested before leaving the factory, and the gas line connection is intact.
