There are not many people who know about the necessity of the function test of the electric ball valve and the knowledge of the relevant items during the test, so we can know about the test of the electric ball valve before we buy it, so today let our technicians tell us about this knowledge.
Electric ball valve is an elastic element that accepts internal pressure and displacement load. It is not only required to have the function required to describe, but also to ensure safe work, which is very important. To check relevant mechanical function and safety. It is necessary to conduct relevant functional tests on the electric ball valve. Especially in the following situations, it is more necessary to conduct experiments:
1. When new products are put into production;
2. When the layout, data and skills of the commodity have been greatly changed after the formal production and can affect the function of the electric ball valve;
3. Resuming production after long-term shutdown;
4. When the labor department conducts production qualification certification or quality inspection as required by the quality monitoring organization, a series of functional experiments are required.
The primary items of the experiment are: pressure test, air tightness test, stress measurement, stiffness measurement, stability test, fatigue test and explosion test. All experiments of non pipe electric ball valves shall comply with the requirements of relevant national or professional specifications and skill prerequisites, which can also be referred to the specifications and skill prerequisites of foreign electric ball valves. At the same time, the electric ball valve products shall be subject to pressure test according to the rules before leaving the factory. The purpose of the experiment is to check the micro strength of the electric ball valve under the condition of overload, and check whether the electric ball valve has the ability to operate safely under the described load. Together, we can check the fineness of the electric ball valve, and check the problems that can exist in the data, layout and manufacturing skills. Based on the above contents, you have some knowledge about the test of electric ball valves. If you want to ask more about electric ball valves, you can ask us.
