Common Causes of Valve Seal Failure

Medium problem: In the actual production process, when the medium passes through the globe valve, the flow resistance will increase due to the influence of some objective factors, and its pressure will decrease at this time. If the staff cannot effectively solve this problem during this process, cavitation will occur when the medium saturated vapor pressure is low. Affected by factors such as squeezing air bubbles, it will lead to defects in the valve seat and sealing performance. invalid. Therefore, in this context, in order to effectively prevent other factors from affecting the production process of high-pressure globe valves, check valves, and low-pressure gate valves, technologies such as vapor deposition are generally used, not only optimizing high-pressure globe valves, check valves, The internal structure of the low-pressure gate valve can effectively reduce the loss of flow resistance, strengthen the long-term protection of the valve seal, and continuously improve the quality of production.

Materials containing suspended and solid impurities: In the process of valve production, if the quality of materials and materials is not properly controlled, it will also lead to seal failure, resulting in problems such as medium leakage. In this process, technicians can continuously optimize the medium and select the appropriate valve according to the operating temperature and pressure, which can effectively reduce the occurrence of related problems to a certain extent. In this process, the staff also needs to carry out regular maintenance, and take effective measures for specific problems to continuously improve the quality of materials. It is necessary to ensure that the selected valve parts meet the relevant production requirements, so as to strengthen the high-pressure cut-off. Reasonable application of valves, check valves, low-pressure gate valves and other valves in the specific work process to avoid quality problems and provide guarantees for the safe use of valves. Factors of pressure: In the specific production process, the start and stop of the factory will cause the pressure to be large and small, and the drastic change of the pressure at this time will lead to dry friction of the sealing surface. If the technician does not analyze this problem, in a short time Heat will be generated inside, which will cause the sealing material to scorch, which will seriously affect the sealing system of the high-pressure globe valve, check valve, and low-pressure gate valve.
