The high-quality work of electromagnetic valve is very crucial, if electromagnetic valve is revealed, electromagnetic valve can not work well, and the operation of whole system is impacted, and need to design a kind of test device, test whether electromagnetic valve leaks.
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, a kind of simple in construction, electromagnetic valve leakage tester reasonable in design, easy to use are provided, it adopts leakage measurement method using differential pressure transducer to test, when Product checking, to carry out low voltage starting test, high voltage startup test, low pressure internal leakage test, internal leakage test and external leakage test respectively, product marking to test passes, test accuracy is high.
In order to solve the problem existing for background technology, the technical solution adopted in the utility model is: it includes entrance, air filter, pressure regulator valve, the first unlatching valve, differential pressure pick-up, pressure transducer, the second unlatching valve, the 3rd unlatching valve, tested product, standard substance；Described entrance is directly connected to air filter, air filter is connected with pressure regulator valve, pressure regulator valve connects the first unlatching valve, second opens valve and is connected the first unlatching valve after differential pressure pick-up parallel connection, second two ends opening valve are connected to tested product and standard substance, being connected with the 3rd unlatching valve between tested product and standard substance, pressure transducer is arranged between the second unlatching valve and tested product.
After adopting said structure, this utility model has the beneficial effect that it adopts leakage measurement method using differential pressure transducer to test, when Product checking, to carry out low voltage starting test, high voltage startup test, low pressure internal leakage test, internal leakage test and external leakage test respectively, product marking to test passes, test accuracy is high.
Accompanying drawing explanation
Fig. 1 is differential pressure measurement principle schematic of the present utility model.
Description of reference numerals: entrance 1, air filter 2, pressure regulator valve 3, first open valve 4, differential pressure pick-up 5, pressure transducer the 6, second unlatching valve the 7, the 3rd unlatching valve 8, tested product 9, standard substance 10.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, this utility model is further elaborated.Should be appreciated that detailed description of the invention described herein is only in order to explain this utility model, be not used to limit this utility model.
As it is shown in figure 1, this detailed description of the invention adopts the following technical scheme that it includes entrance 1, air filter 2, pressure regulator valve the 3, first unlatching valve 4, differential pressure pick-up 5, pressure transducer the 6, second unlatching valve the 7, the 3rd unlatching valve 8, tested product 9, standard substance 10；Described entrance 1 is directly connected to air filter 2, air filter 2 is connected with pressure regulator valve 3, pressure regulator valve 3 connects the first unlatching valve 4, second opens valve 7 and is connected the first unlatching valve 4 after differential pressure pick-up 5 parallel connection, second two ends opening valve 7 are connected to tested product 9 and standard substance 10, being connected with the 3rd unlatching valve 8 between tested product 9 and standard substance 10, pressure transducer 6 is arranged between the second unlatching valve 7 and tested product 9.
The principle of differential pressure measurement is as follows, and compression air enters from entrance 1, by air filter 2, arrives the first unlatching valve 4 through pressure regulator valve 3, and first opens valve 4 opens, and second opens valve 7 connects, and the 3rd opens valve 8 disconnects.Pressurize to tested product 9 and standard substance 10, pressure transducer 6 shows the blowing pressure value, close valve closing first and open valve 4, cut off the electromagnetic valve cavity volume of standard substance 10 and coupling of compressed air source, if pressure transducer 6 detects that electromagnetic valve exists gross leak, then detection is interrupted and reports to the police, and the 3rd opens valve 8 automatically opens up aerofluxus, detection of end；If there is no gross leak, then the second unlatching valve 7 stays open, turn on the gas between tested product 9 and standard substance 10, it is then shut off the second unlatching valve 7, isolate the gas between tested product 9 and standard substance 10, pressure differential therebetween is measured, it is judged that whether tester leaks by highly sensitive differential pressure pick-up 5.When detection terminates, the 3rd opens valve 8 opens, and is entered in air by the gas in tester and tested product 9 and standard substance 10.
In differential pressure measurement loop, standard substance 10 are No leakage airtight cavities with tested product 9 with same volume.Under same action of gas source, if tested product 9 are absent from leakage, then both pressure should be equal, and the pressure reduction that differential pressure pick-up 5 detects is zero；If tested product 9 exist leakage, its pressure can be gradually reduced, and the pressure differential of 5 two pressure chambers of differential pressure pick-up is not zero, and pressure transducer 6 exports a magnitude of voltage, and this value is changed through A/D, sends industrial computer to, processes.
When Product checking, low voltage starting test, high voltage startup test, low pressure internal leakage test, internal leakage test and external leakage test the product marking to test passes to be carried out respectively.
This detailed description of the invention adopts leakage measurement method using differential pressure transducer to test, and test accuracy is high.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that the technical solution of the utility model is made by those of ordinary skill in the art or equivalent replace, without departing from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
