Electric ball valve it has a rotation of 90 degrees, the cock body for the ball, a circular hole or channel through its axis. The main characteristics of the electric ball valve is its compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical often in a closed state, not easy to be eroded by the medium, easy to operate and maintain. Ball valve in the pipeline is mainly used to do the electric ball valve cut off, distribution and change the flow direction of the medium, it only needs to use the operation of 90 degrees of rotation and a small torque can be closed tight.
Electric ball valves are most suitable for on-off and off valves, but recent developments have designed ball valves for throttling and flow control purposes, such as v-type ball valves. Applicable to water, solvent, acid and natural gas and other general working medium, but also applicable to the working conditions of harsh media, such as oxygen, hydrogen peroxide, methane and ethylene, etc., in various industries have been widely used. The ball valve body may be integral or modular.
The installation and maintenance of the electric ball valve mainly do the following:
1、Only when the pressure before and after the ball valve is removed can the ball valve be disassembled and disassembled.
2、The bolts must be tightened symmetrically, step by step and evenly when the ball valve body is reassembled.
3、Cleaning agent should be compatible with rubber parts, plastic parts, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned with gasoline (gb484-89). Clean non-metallic parts with purified water or alcohol.
4、Disassembled individual parts can be washed by immersion. When cleaning must remove all adhere to the wall surface of grease, dirt, glue, dust, etc.
If there are still undecomposed non-metallic parts, use a clean, fine, cleansed silk cloth impregnated with cleaning agent to avoid fiber shedding and adhesion to the parts.
