As a control component in the fluid delivery system, the valve has the functions of cut-off, regulation, diversion, prevention of countercurrent, pressure stabilization, diversion or overflow pressure relief. It is an indispensable control component in many industries. Once the valve fails, especially The leakage event will not only affect the stable operation of the equipment, but may even harm the environment and cause incalculable economic and social losses to the society. Therefore, we should learn to identify and prevent common leakage faults of valves. Generally speaking, common leakage faults of valves include two kinds, namely stuffing box leakage and closing parts leakage. The leakage of stuffing box is the main aspect of running, running, dripping and leaking. This is
As a control component in the fluid delivery system, the valve has the functions of cut-off, regulation, diversion, prevention of countercurrent, pressure stabilization, diversion or overflow pressure relief.

Therefore, we should learn to identify and prevent common leakage faults of valves. Generally speaking, common leakage faults of valves include two kinds, namely stuffing box leakage and closing parts leakage. The leakage of stuffing box is the main aspect of running, running, dripping and leaking, which is often seen.
Preventive measures for valve leakage and steam leakage:
1. All valves must be subjected to different levels of hydraulic test after entering the plant;
2. All valves must be installed with gaskets of corresponding grade before installation;
3. In the process of over-repair, it is necessary to carefully check whether packing is added and whether the packing gland is tightened;
4. Before installation, the valve must be checked for dust, sand, iron oxide and other debris inside the valve. If the above sundries are found, they must be cleaned up before installation;
5. It is necessary to disassemble the valve for maintenance must be ground;
6. In the process of valve installation, all valves must be installed correctly according to the system and pressure, and it is strictly prohibited to install or mix. For this reason, all valves must be numbered and recorded according to the system before installation;
7. When installing the flange door, the fastening parts must be tightened, and the flange bolts must be tightened in a symmetrical direction;
These common failures can take effective measures to prevent, but more important is to choose high-quality high-standard products, Wuhan Xiete Valve Technology Co., Ltd. products through the strict control of professionals, to provide customers with quality products.
