As the control unit in the fluid conveying system, the valve has the functions of cut-off date, regulation, guidance, prevention of countercurrent, pressure regulation, diversion or overflow and pressure relief. It is indispensable for many industrial control components. Once the valve fails, especially The leakage incident not only affects the stable operation of industrial and mining equipment, but also may be harmful to the environment and cause incalculable economic and social losses to the society. We must learn to identify and prevent common leakage failures of valves. Generally speaking, common leakage failures of valves include two types, namely stuffing box leakage and closed leakage. The leakage of stuffing box is the main aspect of operation, bubbling and dripping, which is common in factories. To understand how to deal with valve leakage, steam leakage, we must first understand why there is leakage, steam leakage, is the so-called retreat. The valve must have a good seal to maintain air tightness. If there is a problem with the seal, a leak will occur.

Preventive measures for valve leakage and steam leakage.

1. All valves must be subjected to different levels of hydraulic test after leaving the factory.

2. All valves must be fitted with gaskets of appropriate grade prior to installation.

3. During the overrepair process, check whether the coiling is increased and whether the coiling gland is tightened.

4. Before installing the valve, check whether there is dust, sand, iron oxide and other debris inside the valve. If the above debris must be cleaned before installation.

5. The valve must be disassembled and repaired, and must be grounded.

6. During the valve installation process, all valves must be installed correctly according to the system and pressure, and random mixing is strictly prohibited. For this reason, all valves must be numbered and recorded according to the system before installation.

7. When installing the flange door, the fasteners must be tightened, and the flange bolts must be tightened symmetrically.

We can take effective measures to prevent these common failures, but more importantly, choose high-quality, high-standard products, which can save more time and energy.
