Embodiment Construction
[0017] The accompanying drawings are specific embodiments of the present invention. like figure 1 As shown, this kind of intelligent valve positioner tester includes a gas circuit test bench 1, and a gas circuit input pipe 3, a gas circuit output pipe 4 and two pressure gauge interfaces 5 are reserved on the gas circuit test bed. One end of the connecting pipe 3 is connected to the first mass flow meter 9, the filter pressure regulating valve 8, the manual shut-off valve 7 and the air source 6 in turn through the air pipe 2, and one end of the air output connecting pipe 4 is connected to the second mass flow through the air pipe 2 in turn. Flowmeter 10 and single-acting pneumatic actuator 11;
[0018] The two pressure gauge ports 5 are respectively connected to the 2.5-grade first precision pressure gauge 12 and the 2.5-grade second precision pressure gauge 13. The first precision pressure gauge 12 is connected to the first mass flow meter 9 by air, and the second precision p...

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
[0001] (1) Technical field [0002] The invention relates to a tester, in particular to an intelligent valve positioner tester. [0003] (2) Background technology [0004] At present, when the back pressure test and output flow test are performed on the positioner, it is necessary to frequently replace the test bench and change the gas pipe, which is very troublesome, and it is also very inconvenient to operate during debugging, which seriously affects the production efficiency. [0005] (3) Contents of the invention [0006] In order to make up for the defects of the prior art, the present invention provides a simple and convenient intelligent valve positioner tester. [0007] The present invention is achieved through the following technical solutions: [0008] An intelligent valve positioner tester is characterized in that: it includes a gas path test bench, a gas path input pipe and a gas path output pipe are reserved on the gas path test bench, and the gas path input pipe...
