The working principle of electric ball valve

Electric ball valve is mainly composed of electric actuator and ball valve,the plug body is a sphere with a 90 degree rotation.Electric ball valve is not only a good product that can throttle, cut off, cut off and divert,but also a preferred product in flow control systems.It has characteristics of pressure resistance, temperature resistance, corrosion resistance, small flow resistance, durable, a wide range of applications and so on.

The working principle of electric ball valve:
The electric ball valve mainly depends on the regulation of the electric flow in the electric actuator to operate the ball valve.The electric actuator is the standard signal of input and output of 4-20mA and 220VAC power supply, and the electric unit drives the angular torque of gear, worm wheel and worm to control the opening and closing of the ball valve, distribute and change the flow direction of the medium or adjust the proportion degree of spool rotation, that is, the opening of the valve is proportional to the control fluid, or called the percentage.
The application of electric ball valve:
Electric ball valve does not need human operation, it is dependent on intelligent operation.In the production process,the environmental site determines everything.Electric ball valves used in high pressure, high temperature or low pressure, low temperature environments are not the same.The following points should be noted:
1.For low temperature and low pressure, the material does not need to do much adjustment.
2.In the case of high pressure and high temperature, high temperature and high pressure resistant materials should be selected as the materials of electric ball valves, such as stainless steel, alloy, this kind of material can withstand high pressure and high temperature.
3.The internal parts of the electric ball valve need to be replaced with parts that reduce the damage to the spool, which is also conducive to the flow of the medium and avoid the coking and blockage of the electric ball valve.
4.In the case of the electric ball valve is opened, you can install some machinery to avoid vibration, to prevent the destruction of the internal structure of the electric ball valve spool when opened.
