The working principle of the electric ball valve

by:Mech     2020-11-13

electric ball valve is mainly composed of electric actuators and the ball, the cock body for a sphere, with rotating 90 degrees. Electric ball valve not only can the throttling, globe, cut off, on and off, the good product flow, or flow control system of the preferred products. It has pressure, heat resistance, resistance, small flow resistance, long service life, wide application range, and other characteristics.

mainly by the electric ball valve electric actuator in electric flow control to manipulate the ball valve. 4 - electric actuator input and output signals 20 ma220ac standard signal of power supply, power plant turbine driven gear and worm rotation torque, to control the ball Industrial Valves open and close, distribution, and change the direction of the flow of the medium and the proportion of valve core rotate the valve opening and control fluid is proportional to, or percentage.

electric ball valve does not need manual operation, but smart to ask for. In the process of production, the environment determines all the factors. Under high pressure, high temperature or low pressure, low temperature environment, the use of electric ball embellish of each different. Should pay attention to the following:

1 for low temperature low pressure, the material does not need too big to do adjustment.

2 in the case of high pressure, high temperature, should be chosen by the resistance to high temperature and high pressure material as electric ball valve material, such as: stainless steel, alloy, this kind of material can bear high pressure and high temperature.

3 electric ball valve internal parts need to reduce the damage to the valve core, as well as to the flow of the medium, avoid electric ball valve coking and clogging.

4 under the condition of the electric ball Industrial Valves open, you can install some free vibration machinery, prevent damage when opening the internal structure of the electric ball valve valve core.
