Abstract

The invention discloses a performance testing instrument for a thermoelectric electromagnetic valve, and the performance testing instrument comprises a casing. The performance testing instrument is characterized in that the surface of the casing is provided with a control panel; an electromagnetic valve detecting circuit is arranged in the casing; and the electromagnetic valve detecting circuit comprises a mater control MCU (micro control unit), a constant-current source part for generating a current needed by test, a voltage measuring module for testing a voltage between two ends of an electromagnetic valve, and an infrared emission judging circuit part for judging the opening and the closing of the electromagnetic valve. The performance testing instrument is applicable to the performance test and the ageing test of various thermoelectric electromagnetic valves, flame failure protection thermoelectric electromagnetic valves and the like of gas appliances, and has the main functions of quantitative test, qualitative test, the ageing test, manual test, internal resistance test ad the like. In addition, the instrument has an internal resistance test function, can be independently used as a low resistance testing instrument, and the resistance value of a primary winding, a secondary winding or other low resistors can be tested by using a special testing clip.

Description

technical field

[0001] The invention relates to performance testing equipment for a thermoelectric solenoid valve, in particular to a performance tester for a thermoelectric solenoid valve. Background technique

[0002] Solenoid valves are widely used in all walks of life, but there is no convenient and effective detection method for the performance and quality of solenoid valves, which has seriously affected and restricted the development, production and use of solenoid valves. The thermoelectric solenoid valve in the solenoid valve is generally used in gas cookers, and its performance requirements are relatively high. Therefore, it is necessary to effectively detect its performance.

[0003] Chinese Patent Document No. CN101881703A disclosed a solenoid valve performance detection system on November 10, 2010, which can conveniently detect the working process of the solenoid valve and evaluate its quality and performance. It is mainly composed of voltage generator, sensor, ...
