Electric Ball Valve It has the action of rotating 90 degrees, the plug body is a sphere, with a circular through hole or passage through its axis. Electric ball valve is characterized by its compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often closed state, easy to be media erosion, easy to operate and repair. Ball valve in the pipeline is mainly used to do electric ball valve cut off, distribution and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small turning moment can be closed tight. Electric ball valve is best to do the switch, cut off the use of valves, but the recent development of the ball valve has been designed so that it has the throttle and control of flow purposes, such as V-type ball valve. For water, solvents, acids and natural gas and other general working medium, but also for poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, etc., are widely used in various industries. Ball valve body can be a whole, it can be combined. Electric ball valve installation and maintenance mainly to do the following points: 1, only remove the pressure before and after the ball valve, the valve can be demolished decomposition operation. 2, the ball valve body reassemble the bolt must be symmetrical, step by step, evenly tightened. 3, the cleaning agent should be ball valve rubber parts, plastic parts, metal parts and working medium (such as gas) are compatible. Working medium for gas, gasoline (GB484-89) can be used to clean metal parts. Non-metallic parts with pure water or alcohol cleaning. 4, the decomposition of a single part can be cleaned with immersion. Cleaning to remove all adhesion on the wall of grease, dirt, glue, dust and so on. If unsplit pieces of nonmetallic metal are left, they can be scrubbed with a clean, fine, silk-dipped detergent fabric (to prevent the fibers from sticking to the parts).
