The electric ball valve has the action of rotating 90 degrees. The cock body is a sphere with a circular through hole or channel passing through its axis. The ball valve is mainly used in the pipeline as an electric ball valve to cut off, distribute and change the flow direction of the medium. It only needs to rotate 90 degrees and a small torque to close tightly. The ball valve is most suitable for use as a switch and shut-off valve. The development has designed the ball valve to throttle and control the flow, such as the V-shaped ball valve. The main characteristics of the electric ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easy to be eroded by the medium. It is easy to operate and maintain. It is suitable for water, solvents, acids and natural gas. The working medium is also suitable for the medium with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., which are widely used in various industries. The ball valve body can be integral or combined.
PRINCIPLE
The electric ball valve is a combination of a plug-type ball valve and an electric actuator. The ball valve body structure is a spool that rotates 90 degrees. The electric actuator inputs a standard signal of 0-10 mA. The motor group drives the gear and worm gear angle torque. Adjust the valve with the switch box. Its use is mainly produced by the amount of current and adjustment operations.
COMPOSITION
Commonly used electric actuators include multi-turn, single-turn, intelligent, quarter-turn actuators, linear-stroke electric actuators, explosion-proof actuators, and small-sized actuators. The ball valves mainly include floating ball valves, fixed ball valves, O-shaped ball valves, V-shaped ball valves, and three-way ball valves. The execution and ball valve configuration together can produce diversified products. You can also add a control box for remote operation, and add other accessories to the actuator to achieve more functional applications, such as adding an electrical positioner to adjust flow, and resistance/current valve position converters can be used to control valves. Indication and control of the position opening, the hand wheel mechanism can be operated manually when there is no current, and other commonly used accessories include insulating sleeves, explosion-proof travel switches, etc. The initial selection can be selected according to the working conditions.
APPLICATION
Electric ball valve accounts have now been widely used in oil, natural gas, medicine, food, hydropower, nuclear power, electricity, water supply and drainage, heating, metallurgy and other industries, and they are critical mechanical products for national defense construction. It is also an indispensable product for technological construction. It occupies a lot of the market share, mainly because of various reasons such as strong function, small size, reliable performance, large circulation capacity, light and cheap people, and remote control of electric ball valves. Electric ball valves are not only throttling, shutting off, cutting off, etc. A good product for on-off and diversion, or a fierce product of choice in a flow regulation system. It has many characteristics such as pressure resistance, temperature resistance, corrosion resistance, low flow resistance, long service life, and wide application range.
