The maintenance of control valve is similar to the maintenance of general instruments, which can be divided into passive maintenance, preventive maintenance and predictive maintenance. Passive maintenance is a maintenance method that can only be carried out when the control valve and other equipment have faults. Because the equipment is maintained only after failure, the production process is often stopped, and even equipment damage or casualties occur in serious cases. Passive maintenance is the maintenance that is not expected in the production process, and preventive maintenance is a maintenance method based on past operating experience and time. For example, the common regular maintenance is preventive maintenance. It formulates corresponding maintenance schedules according to the operation of different equipment, and carries out maintenance when the equipment has not failed. Since maintenance is carried out without failure, the probability of failure can be greatly reduced. However, this maintenance method does not analyze the actual situation of the regulating valve currently in use, and often disassembles and checks the regulating valve that can be used for a certain time, wasting time and resources. Predictive maintenance starts from the analysis of the data of the currently used control valve, foresees the state of the control valve, so that the control valve can be used to a large extent.

I hope that every friend can have a better understanding of each part of the electric three-way ball valve, so that each part can be better operated in the actual use specifications. Especially in the process of use, the temperature should also be better mastered. Once the overall temperature tolerance is exceeded, the equipment cannot work normally, so the temperature of each region should be more comprehensively mastered. How promising is the development prospect of relevant pneumatic ball valves? What should we pay attention to in the installation and assembly of electric ball valves? Tell you in detail the secret of longevity of pneumatic butterfly valves: careful maintenance and regular cleaning are the key to the failure of electric ball valves. How to repair them? Understand the product characteristics. The key is to eliminate the condition of pneumatic ball valves in use
