To first understand how to deal with valve leakage and steam leakage, it is necessary to first understand why there is leakage and steam leakage, as the saying goes, know the cause and understand the reason behind it. Valves must maintain airtightness and have good sealing. If there is a problem with the seal, there will be a phenomenon of air leakage.

As a control component in fluid transportation systems, valves have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. They are control elements in many industrial and mining facilities. Once valves fail, especially in the event of leakage, they not only affect the stable operation of industrial and mining equipment, but may also harm the environment and cause incalculable economic and social losses to society. It is necessary to learn to identify and prevent common leakage faults of valves. Generally speaking, common leakage faults of valves include two types: stuffing box leakage and closure leakage. Leakage of stuffing boxes is the main aspect of running, emitting, dripping, and leaking, which is often seen in factories.
Preventive measures for valve leakage and steam leakage.
1. All valves must undergo different levels of hydrostatic testing after entering the factory.
2. All valves must be equipped with gaskets of the corresponding grade before installation.
3. During the repair process, it is necessary to carefully check whether there is any added packing and whether the packing cover is tightened.
Before installation, the valve must be checked for dust, sand, iron oxide, and other debris inside the valve. If there are any of the above-mentioned debris, they must be cleaned before installation.
Valves that require disassembly and maintenance must be ground.
During the valve installation process, all valves must be installed correctly according to the system and pressure, and random or mixed installation is strictly prohibited. All valves must be numbered according to the system and recorded before installation.
7. When installing the flange door, the fasteners must be tightened, and the flange bolts must be tightened symmetrically in sequence.
We can take effective measures to prevent these common faults, but it is more important to choose high-quality and high standard products, which can save more time and energy in mining.
