The pneumatic ball valve is an additional limiting device based on the original performance of the pneumatic ball valve, which is locked with double nuts at the maximum expansion. The pipeline can expand and contract freely in the allowable expansion and contraction amount. Once it exceeds its large expansion and contraction amount, it will reach the limit to ensure the safe operation of the pipeline. It is especially suitable for the connection in the pipeline with vibration or a certain slope and turn. Double flange pneumatic ball valve is also called double flange pneumatic ball valve, double flange power transmission expansion joint, and double flange pneumatic ball valve. The product is composed of compensation joint, short pipe flange, force transfer screw and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and the installation error of the compensation pipeline. The double flange force transfer expansion device cannot absorb the axial displacement.
The double flange pneumatic ball valve is mainly used for the connection of pumps, valves and other accessories. Applicable media: The pneumatic ball valve is suitable for conveying seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and granular powder with temperature not higher than 250 degrees. Scope of application: The pneumatic ball valve has good comprehensive performance. It is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, water heating, fire protection, electricity, etc. Brief Description of Installation: Double flange pneumatic ball valve is applicable to the connection mode in which both sides are flanges. During installation, adjust the installation length between the two ends of the product and the pipeline or flange. After installation and welding, tighten the gland bolts diagonally and evenly to make them a whole. There is a certain displacement, which is convenient for installation and maintenance. It can be adjusted according to the site size. During operation, the axial thrust can be transmitted to the whole pipeline. Product material: 235 carbon steel, stainless steel, cast steel, ductile iron, etc. Select different materials and models according to different purposes.
