Let's talk about these 3 connection methods of pneumatic ceramic double gate valves

Let's take a look at several connection methods of ceramic double gate valves, the connection methods between ceramic double gate valves are various, and different connection methods are also used in different occasions, with practical connection methods to reflect the value of ceramic double gate valves, different connections in the connection methods also have different skills, let's talk about how to connect the pneumatic ceramic double gate valves? 1. Threaded connection: The ball valve with threaded connection is mainly a ball valve with a nominal passage of less than 50mm. If the bore size is too large, it is difficult to install and seal the connection. Threaded connections are usually machined into tapered or straight pipe threads at the inlet and outlet ends of ball valves, which allow them to be connected to tapered threaded fittings or pipes. Because of the potential for large leaking channels in such connections, these channels can be plugged with sealants, sealing tape, or packing. If the material of the valve body can be welded, but the coefficient of expansion varies greatly, or the operating temperature varies widely, the threaded connection must be honeysealed. To facilitate the installation and removal of threaded ball valves, fittings are available at the appropriate location in the piping system. Ball valves with a nominal diameter of less than 50 mm can use a pipe sleeve as a pipe joint, and the thread of the pipe sleeve joint connects the two parts of the connection together. 2. Flange connection: The ball valve with flange connection is more convenient to install and disassemble, but the flange connection is heavier than the ball valve with threaded connection, and the corresponding price is also high, so it is suitable for pipe connection with various diameters and pressures. When the temperature exceeds 350 degrees, the bolts, gaskets and flanges become relaxed, and the load of the bolts is significantly reduced, and the flange connection with great force may leak. 3. Welded connection: Welded ball valves with nominal diameter below 50mm usually have welded sockets to undertake the pipes at the end of the load plane. Because socket welding forms a gap between the socket and the pipeline, it is possible that the gap is corroded by some media, and the vibration of the pipeline will fatigue the connection part, so the use of socket welding is limited to a certain extent. Welded connections are suitable for a wide range of pressures and temperatures, and are more reliable than flange connections when used in more loaded conditions. However, it is difficult to remove and reinstall the ball valve with welded connections, so its use is limited to situations where it can usually operate reliably for a long time, or when the conditions of use are high and the temperature is high.
