What are the reasons that affect the service life of butterfly valves

Butterfly valves are a common type of valve in industrial production piping systems. However, the service life of a butterfly valve is often affected by a variety of factors. The following butterfly valve manufacturers summarize the possible reasons that affect the service life of butterfly valves: 1. Improper installation and maintenance of equipment: Butterfly valve manufacturers believe that improper installation or maintenance of butterfly valves often leads to the destruction of valve seats. For example, if the internal structure of the valve body and piping are not cleaned prior to installation, residues in the piping may cause damage to the seat of the butterfly valve. Therefore, it is recommended that the operator perform regular maintenance and maintenance on the butterfly valve to ensure that the valve is in normal condition and avoid damage to the sealing ring of the valve seat. 2. The quality of the equipment: when the butterfly valve manufacturer does not pay attention to the details when talking about the processing quality of the seat of the butterfly valve, it will lead to cracking, porosity and other problems on the seat sealing ring. In addition, the operator selects the wrong butterfly valve model, which can cause the valve to mismatch the load standard, resulting in damage to the seat seal. Therefore, choosing the right butterfly valve model is important to extend the life of the equipment. 3. Pay attention to the flushing of the protruding face: Although the butterfly valve is stable, the flushing of the media may affect the life cycle of the valve seat. Due to the washout of the medium, the seat seal may be located inside the pipeline. Continuous flushing will cause corrosion of the seat seals and damage to the protruding surfaces of the seats. In addition, the butterfly plate rubs against the seat every time it opens and closes, which can adversely affect the protruding surface over time. In summary, maintaining the long-term stable operation of the equipment will be a key factor in maintaining the service life of the butterfly valve. Operators should follow proper installation and maintenance procedures and select the correct type of butterfly valve to ensure that all parts of the equipment are functioning properly and that the service life of the equipment is maximized.

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.
