Summarize the connection method of Guangzhou double flange electric ball valve in the pipeline Summarize the connection method of Guangzhou double flange electric ball valve in the pipeline: Hengchang technicians explained that Guangzhou double flange electric ball valve is a connector between pipes and valves. A device connected to convey gas, liquid or fluid with solid particles. Generally, after being pressurized by blowers, compressors, pumps and boilers, the fluid flows from the high-pressure part of the pipeline to the low-pressure part, or can be transported by the pressure or gravity of the fluid itself.
Guangzhou double flange electric ball valve is widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. The connection method of Guangzhou double flange electric ball valve between the inlet and outlet pipes on the valve and equipment is determined by the nature, pressure and temperature of the fluid, as well as the material, size and installation site of the pipe, which mainly includes threaded connection. Flange connection, socket connection and welding. Threaded connection is mainly applicable to small diameter pipes. During connection, the thread connection part shall be wrapped with fluoroplastic sealing tape, or coated with thick paint, hemp wire and other sealing materials to prevent leakage. When the pressure is above 1.6 MPa, the pipe end face is usually sealed with gaskets. This connection method is simple and can be disassembled and reassembled, but the movable joint must be installed at the appropriate place of the pipeline to facilitate disassembly and assembly.
Guangzhou double flange electric ball valve is applicable to a wide range of pipe diameters. During connection, different flanges and sealing gaskets shall be selected according to the nature, pressure and temperature of the fluid, and bolts shall be used to clamp the gasket to keep the seal. Flange connection is mostly adopted at the pipe sections that need frequent disassembly and assembly and the places where pipes are connected with equipment. Socket connection is mainly used for connection between cast iron pipes, concrete pipes, clay pipes and their connectors, and only applicable to water supply, drainage and gas pipes working under low pressure and normal temperature. During connection, hemp, cotton or asbestos rope shall be filled in the groove of socket and spigot, and then asbestos cement or lead and other materials shall be used for filling. Valve sealing ring can also be filled in the socket and spigot to make it flexible and allow a small amount of pipe movement.
