Prevention Measures for Water and Steam Leakage of Valve

To solve the problem of valve water and steam leakage, we need to know why it happens. We need to make sure to seal the valve well, so that it can maintain air tightness. If something goes wrong with sealing, there will be a leakage.

As a control part in the system of fluid delivery, valve has functions of cut-off, regulation, diversion, prevent reverse flow, voltage stabilization, etc. It's a necessary control element in numerous industry and mining. However, once valve malfunctions, especially when it comes to leakage, it would influence the stable running of industrial and mining equipment, it may even do harm to environment and cause incalculable economic and social losses. We need to know how to identify and prevent the common leakage problems of valve. Generally, there are two types of the common leakage problems, which is stuffing box leakage and closure member leakage. Steaming, dripping and leaking are the main troubles for Stuffing box, which always happen in a factory.

The prevention measures for valve water and steam leakage:
1. All valves need to pass different levels of hydraulic test.
2. All valves have to equip the valve with the matching gasket before installation.
3. During the fix process, we should check carefully whether the valve has packing and the packing gland is tightened or not.
4. Before installation, we should check if there is dust, sand, iron oxide or others in the valve. If there is, the valve should be cleaned.
5.There should be an abrasive treatment for those valves that need to be disassembled for repair.
6.During the installation process, all valves have to be installed under the right system and pressure. Do not mess up and mix it. So they should be numbered and well recorded in a system.
7.Tighten the fastener. This should be done under the symmetry direction and one by one.

We can take effective measures to prevent those common problems. But the most important thing is to choose products with high quality and standard so that it can save more time and energy for industry and mining.
