The double flange electric ball valve has a wide range of applications. It is mainly used for the connection of pumps, valves and other accessories. It is composed of flange electric ball valve, short pipe flange, power transmission screw and other components, which can reduce the pressure thrust (blind plate force) of the connected parts and compensate for the installation error of the pipeline. The double flange electric ball valve cannot absorb the axial displacement. The double flange electric ball valve is mainly used in the electric ball valve with both sides connected to the flange. During installation, adjust the installation length of both ends of the product and the flange, and tighten the gland bolts diagonally in order to make them a whole with a certain displacement.
The electric ball valve mainly relies on the angular displacement of the ball to absorb or compensate the transverse displacement of the electric ball valve in one or more directions. The pneumatic valve should be used in pairs, and a single spherical pneumatic valve has no compensation capacity. The service life of the double flange electric ball valve is affected by many factors. Because it is connected with the electric ball valve and other equipment, the temperature, size, fluidity and corrosivity of the whole equipment of the electric ball valve will affect the double flange electric ball valve during use. So let's talk about the impact of these factors on the electric ball valve. The temperature control range of double flange electric ball valve during operation is between 180-200 degrees. The temperature at this stage is more suitable for electric ball valve, which will not affect the product and damage the product. The double flange electric ball valve can transport both powdery particles and liquid materials, with strong fluidity and low viscosity, which is convenient for transportation. For corrosive materials, we have to consider that, because they are corrosive, if double flange electric ball valves are used for transportation, electric ball valves or other equipment such as electric ball valves need to be replaced regularly. The temperature, size, fluidity and corrosivity of materials shall be strictly controlled when the double flange power transmission joint is conveying materials to avoid controllable problems.
