Industrial valve pressure testing method

Today, Xiaobian will introduce to you the pressure test method of industrial valves, the commonly used medium for valve pressure test is water, oil, air, steam, nitrogen, etc., and the pressure test methods of various industrial valves including pneumatic valves are as follows:

The problem of valve not being tightly closed and its solution

In general, if it is not tightly closed, first confirm to see if the valve is closed in place, if it has been closed in place, there is still leakage can not be sealed, then check the sealing surface, some valves are detachable, then take them out for grinding, test again, of course, if it is not closed strictly, then it must be returned to the factory for maintenance or replacement of the valve, so as not to affect the normal use of the valve and problems such as working condition accidents.

Introduction to Valve Materials

Today, Xiaobian will talk to you about the knowledge of valve material

Valve grease curing

When the valve is greased, the problem of grease injection is often ignored. After the grease injection gun is refueled, the operator selects the valve and the grease injection connection method to carry out the grease injection operation. There are two situations: on the one hand, the amount of grease injection is small, the grease injection is insufficient, and the sealing surface is worn faster due to the lack of lubricant. On the other hand, excessive grease injection causes waste. The reason is that there is no precise calculation of the sealing capacity of different valves according to the type of valve type. The sealing capacity can be calculated according to the size and type of valve, and then the appropriate amount of grease can be injected reasonably
