The invention relates to an automatic control valve life tester, which mainly comprises a control system and a durability tester, wherein the durability tester comprises a valve durability testing system, an automotive gas charging-port one-way valve durability testing system and a liquefied petroleum gas cylinder self-closing device durability testing system. The tester is mainly used for the test of the opening and closing of a valve and the total travel torque and the durability tests of a self-closing device, an automotive gas charging port one-way valve and a liquefied petroleum gas cylinder. The three systems in the durability tester are positioned in the same frame and independent of one another and controlled by different software interfaces. When the automatic control valve life tester is used for testing the life of the valve, the test can be completed quickly, numerical values such as the pressure, the time and the test times are displayed in the test process, the test result can be stored automatically and also can be printed, and the test result can automatically stored after power is cut off.
Description
technical field The invention relates to the field of valve durability testing, in particular to an automatic control valve life testing machine. Background technique Valve life is an important indicator of valve quality and reliability assessment. At present, there are more than 4,000 valve factories in my country. When the wear between the valve plate and the valve seat reaches a certain level, the valve will leak beyond the standard after it is closed. Therefore, many products will not expose quality problems in a short period of time. After a period of use, their quality defects will appear. Whether users, valve manufacturers or testing organizations want to understand and master the reliability of valve quality in a short period of time, they must rely on valve life test devices. However, there is no ideal device for testing them. Contents of the invention The technical problem to be solved by the present invention is to provide an automatic control valve life testi...
