How to deal with valve leakage, leakage of steam, we must first understand why there is leakage, leakage of steam, know it and know why. Valve to maintain air tightness, must have a good seal. If there is a problem with the seal, there will be air leakage. As a control component in the fluid conveying 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 for many industrial and mining industries. Once the valve fails, especially The leakage incident will not only affect the stable operation of industrial and mining equipment, but may even harm the environment and cause immeasurable economic and social
How to deal with valve leakage, leakage of steam, we must first understand why there is leakage, leakage of steam, know it and know why. Valve to maintain air tightness, must have a good seal. If there is a problem with the seal, there will be air leakage.
As a control component in the fluid conveying system, the valve has the functions of cut-off, regulation, diversion, prevention of countercurrent, pressure stabilization, diversion or overflow and pressure relief. It is an indispensable control component for many industries and mines. Once the valve fails, especially The leakage incident will not only affect the stable operation of industrial and mining equipment, but may even endanger the environment and cause incalculable economic and social losses to the society. Must learn to identify and prevent the common leakage of the valve fault, in general, the common leakage of the valve fault includes two kinds, namely the stuffing box leakage and closure leakage. The leakage of stuffing box is the main aspect of running, running, dripping and leaking, which is often seen in factories.
About the valve leakage, leakage of steam prevention measures.
1. All valves must be subjected to different levels of hydraulic test after entering the plant.
2. All valves must be installed before installation of the appropriate level of gasket.
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 debris must be cleaned 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.
We can take effective measures to prevent these common failures, but it is more important to choose high-quality and high-standard products, so that we can save more time and energy.
