[0002] Gas valve is a product whose working medium is gas and has on-off function. figure 1 The shown gas valve needs to be tested for thrust after it is manufactured; two methods are mainly used at present. One is to use the vertical method for testing, with the valve nozzle facing up and a pressure sensor installed below it. The test of the thrust valve; the second is to adopt the method of horizontal pulley, the nozzle is at the level, and a pressure sensor is installed in the opposite direction. The test device of this method cannot effectively overcome the test error caused by friction, resulting in inaccurate measurement data. and high manufacturing cost

The invention discloses a gas valve thrust test device, comprising a fixing mechanism, a rotating mechanism and a connecting mechanism, the fixing mechanism comprises a base plate and a fixed block, the base plate is horizontally mounted on a workbench, and the fixed block is mounted on the base plate; the rotating mechanism comprises a rocker arm, the rocker arm is rotatably mounted on the base plate by virtue of the connecting mechanism; in an initial state, the rocker arm is vertical to the base plate, a gas valve and a force sensor are horizontally mounted on the rocker arm, and the forcesensor is fixedly mounted on the fixed block; during test, the gas valve is connected with a gas source by virtue of a high pressure hose, a nozzle at one side is opened by virtue of a gas valve switch, and a gas flow drives the rocker arm to rotate; and based on a lever principle and a reading displayed by the force sensor, a thrust value of the gas valve after the gas is blown out is obtained. The gas valve thrust test device disclosed by the invention can realize unidirectional and bidirectional thrust test on the valve, can complete the thrust test on the valve by virtue of manual operation of a single person and has the characteristics of reliable performance, strong security, accurate measurement, convenience in use and low cost.
Description
technical field [0001] The invention relates to the technical field of valve testing, in particular to a gas valve thrust testing device. Background technique [0002] Gas valve is a product whose working medium is gas and has on-off function. figure 1 The shown gas valve needs to be tested for thrust after it is manufactured; two methods are mainly used at present. One is to use the vertical method for testing, with the valve nozzle facing up and a pressure sensor installed below it. The test of the thrust valve; the second is to adopt the method of horizontal pulley, the nozzle is at the level, and a pressure sensor is installed in the opposite direction. The test device of this method cannot effectively overcome the test error caused by friction, resulting in inaccurate measurement data. And the manufacturing cost is high. Contents of the invention [0003] In view of the deficiencies in the above problems, the present invention provides a gas valve thrust testing dev...
