The construction principle of electric ball valve

The electric ball valve is mainly used to cut off or connect the medium in the pipeline. It can also be used for fluid adjustment and control. Today, the editor will introduce to you the construction principle of the electric ball valve. Let's have a brief understanding together:

The structure of the electric ball valve is composed of only a few parts, which saves data consumption; small size, light weight, small solenoid valve installation size, electric ball valve structure diagram, small driving torque, pressure regulating valve, simple and agile operation, only need to rotate 90° It can be opened and closed quickly; and it also has good flow regulation and sealing characteristics at the same time. In the application of large and medium caliber, medium and low pressure, electric ball valve is the dominant valve form. When the electric ball valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop of the valve actuator through the valve is very small, so it has better flow control characteristics.

　　 Electric ball valve has two sealing types: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate. Valves with metal seals generally have a longer life than valves with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the disadvantage of being limited by temperature. If the electric ball valve is requested to be used as a flow control, it is important to accurately select the size and type of the valve. The construction principle of the electric ball valve is particularly suitable for manufacturing large diameter valves.

　　The electric ball valve is not only widely used in general industries such as petroleum, gas, chemical, water disposal, but also used in the cooling water system of thermal power stations. Commonly used electric ball valves include wafer type electric ball valves and flange type electric ball valves. Wafer type electric ball valve uses double-head bolts to connect the valve between the two pipe flanges. Flange type electric ball valve has flanges on the valve, and the gas solenoid valve uses bolts to connect the two flanges on the valve to the pipe. Lan Shang. The strength performance of the valve refers to the ability of the valve to withstand medium pressure. The valve is a mechanical product that is subjected to internal pressure, so it must have sufficient strength and rigidity to ensure long-term use without cracking or deformation.
