The invention relates to a tester and particularly discloses an intelligent valve locator tester. The intelligent valve locator tester comprises a gas circuit test stand, a gas circuit input connecting tube, a gas circuit output connecting tube and two pressure gauge interfaces are reserved on the gas circuit test stand, the gas circuit input connecting tube is sequentially connected with a first mass flow meter, a filter pressure regulating valve, a manual stop valve and a gas source. The gas circuit output connecting tube is sequentially connected with a second mass flow meter and a single-acting pneumatic actuator. A first precision pressure gauge and a second precision pressure gauge are connected, the first precision pressure gauge is connected with a first mass flow meter gas circuit and a 4-20 milliampere current input interface, and the second precision pressure gauge is connected with a second mass flow meter gas circuit and a 4-20 milliampere current output interface. The tester is simple in structure and convenient to operate, the output flow and a relation curve of the back pressure can be tested simultaneously, the testing speed of an existing intelligent valve locator in production can be greatly increased, and production efficiency is improved.
Description
(1) Technical field [0001] The invention relates to a tester, in particular to an intelligent valve positioner tester. (2) Background technology [0002] At present, when performing back pressure test and output flow test on the positioner, it is necessary to frequently replace the test bench and change the air pipe, which is very troublesome, and it is also very inconvenient to operate during debugging, which seriously affects the production efficiency.
