Accompanying drawing explanation
Fig. 1 is the principle schematic according to valve test system of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, valve test system according to the present invention is further described in detail.
Please refer to Fig. 1, valve test system according to the present invention comprises: source of the gas 1, stop valve 2, first pressure transducer 7, solenoid valve 3, automatically controlled throttling valve 4, second pressure transducer 8, filtrator 5, data collector 10, control device 9 and industrial computer 11.Wherein, source of the gas 1 is used to provide the gas that system is carried out needed for impulse test, and can adopt any applicable gas supply device, gas wherein such as adopts pressurized air, is not specifically limited at this.Stop valve 2 release of gas when the supply of gas when helping test and off-test, can omit according to actual conditions.There is provided solenoid valve 3 to control the supply of impact air, existing solenoid valve can be adopted according to actual conditions, such as bi-bit bi-pass large discharge solenoid valve.Automatically controlled throttling valve 4 is used for controlling the flow of gas, even if any for this area, can adopt any available throttling valve according to actual needs.Filtrator is used for filtering gas, to make gas purer, according to the gas station that reality adopts, can omit.Valve part 6 to be tested is the valve of impulse test to be subjected, and the valve part that this pilot system is suitable for is generally normally closed type valve (such as normally closed pilot-operated type bi-bit bi-pass electrically operated valve).
Below valve test system is according to the preferred embodiment of the invention described in detail.
Composition graphs 1, in valve test system according to the preferred embodiment of the invention, source of the gas 1, stop valve 2, first pressure transducer 7, solenoid valve 3, automatically controlled throttling valve 4, second pressure transducer 8 and filtrator 5 by pipeline (such as, metal tubes) be communicated with in turn, and filtrator 5 is communicated to valve part 6 to be tested further.Data collector 10 is connected with the first pressure transducer 7 and the second pressure transducer 8, to gather the second pressure feedback value of the first pressure feedback value from the first pressure transducer and the second pressure transducer respectively.Control device 9 is connected with solenoid valve 3 and automatically controlled throttling valve 4, with the aperture (that is, opening degree) of the unlatching of Controlling solenoid valve and automatically controlled throttling valve.Industrial computer 11 is connected with control device 9 with data collector 10, and three forms feedback control loop.Industrial computer 11 receives the first pressure feedback value from data collector and the second pressure feedback value, and controls the action electric signal that control device sends according to this.Particularly, when receiving the first pressure feedback value that data collector transmits, industrial computer compares this first pressure feedback value and the size of impact bleed pressure value preset, if the first pressure feedback value reaches the impact bleed pressure value preset, it assigns solenoid valve open command to control device, so that opens solenoid valve, to the valve part supply shock gas in downstream; When receiving the second pressure feedback value that data collector transmits, industrial computer is worth over time according to the second pressure that the second pressure transducer feeds back and calculates the actual of gas in pipeline corresponding to the second pressure transducer with acquisition time changing value and build pressure rate value, and press rate value to compare with building of presetting this actual pressure rate value of building, automatically controlled throttle valve opening regulating command is assigned to control device according to comparative result, thus control the aperture of automatically controlled throttling valve, guarantee that the rate of pressurization of impact air meets the demands.
