The service life of knife gate valve is a problem that people are more concerned about. What methods can we use to prolong its service life in the process of production and use? Let’s get to know each other.
In order to ensure the use of knife gate valve, Houmin, the material selection of the valve is very important. The material must be selected according to the working conditions, otherwise it will inevitably reduce the service life of the valve. In the process of use, the maintenance of the valve should also be strengthened. Such as regular dirt removal, regular grease injection, regular maintenance, etc., to extend the service life of the valve. Each driving device has its own stress characteristics, which are related to different specific pressure values on the sealing surface, as well as the stress of the valve rod, valve rod nut and other parts. When the electric device is closed to the end point, it will cause impact load on the sealing surface, especially the stop valve.
When the valve is installed and used in the open air, the working conditions are very poor, because it is easy to rust due to wind and rain, and sometimes even damage the lubrication. If dust and sand fall into the connection of parts, the wear of parts will be accelerated. The knife gate valve as a whole is in the salt fog and will be corroded by chloride ions in the salt fog. The knife gate valve is very easy to rust and lose its due function. The material selection of the knife gate valve should consider the corrosion resistance of chloride ions, and pay attention to the painting of the outer surface at the same time. If the valve is installed and used underground, the valve with extended full welding Belt should be selected to prevent the knife gate valve from being corroded by groundwater and mud and sand after being buried, and damaging the connecting parts and moving parts of the valve.
Therefore, in the long-term use process, knife gate valve can improve its service life from these aspects, so as to meet people’s needs.
