It is to input gas from sample air inlet that traditional four-loop protection valve opens pressure detection method, when gas outlet begins with gas output, and the input air pressure value of detection air inlet.Traditional pressure detection method of opening has testing result unstable and the phenomenon of instability in actual applications.Therefore, a kind of accuracy of detection of design is high, four-loop protection valve opening pressure detecting device that stability is high and method, becomes problem demanding prompt solution.
Summary of the invention
The invention aims to overcome the detection four-loop protection valve existed in actual applications at present to open the deficiency that pressure detecting precision and stability is low, it is provided that a kind of four-loop protection valve that detects opens pressure detecting precision and the higher detection device of detection efficiency and detection method.
The technical scheme is that a kind of four-loop protection valve opening pressure detecting device; the base plate on stand can be fixed on including one; being respectively fixed with four cylinders by fixation kit on base plate, each cylinder is correspondingly arranged at the seam of four-loop protection valve, and each cylinder is equipped with plug；Cylinder air inlet air inlet, makes the plug extension being connected with cylinder, blocks the interface of four-loop protection valve, wherein,
Four cylinders are respectively, corresponding four-loop protection valve interface lower cylinder flatly, the right cylinder of corresponding two mouthfuls of four-loop protection valve interface, three mouthfuls of corresponding four-loop protection valve interface and the upper cylinder of four mouthfuls, the left cylinder of corresponding five mouthfuls of four-loop protection valve interface；
Fixation kit includes, the air cylinder fixed plate being fixed on base plate, and each cylinder is fixed in the air cylinder fixed plate of correspondence, and air cylinder fixed plate is provided with rear fixed plate, and fix vertical with air cylinder fixed plate of rear fixed plate is connected.
Connect on described plug and have rubber plug.
Described upper cylinder is twin shaft cylinder, and twin shaft cylinder connects plug by cylinder link.
Described each cylinder both sides are provided with reinforcement, and reinforcement is connected with air cylinder fixed plate and rear fixed plate respectively.
Present invention also offers a kind of employing four-loop protection valve and open pressure detection method, comprise the following steps:
Step 1) controls the inlet charge of each cylinder, makes the plug extension being connected with cylinder, it is achieved the clamping of four-loop protection valve product to be measured, each interface of automatic plugging and connection system gas circuit；
Step 2) computer controlled electric Proportion valve and sets air pressure to system input, then inflated flatly to four-loop protection valve by cutoff hole plug within, be connected with air by four-loop protection valve two mouthfuls by a cutoff hole simultaneously, and other interface blocks；
Step 3) adjusts the adjustment screw of four-loop protection valve two mouthfuls, when sensor survey four-loop protection valve two mouthfuls has relatively steady pressure value, and record four-loop protection valve pressure flatly, it is the unlatching pressure of this interface；
Step 4) repeat step 2), step 3), in turn adjust four-loop protection valve three mouthfuls, four mouthfuls and the unlatching pressure of five mouthfuls.
The invention have the advantage that four-loop protection valve opening pressure detecting device test four-loop protection valve unlatching stress test efficiency and the measuring accuracy of the present invention are higher.Fixation kit is simple and practical, and clamping precision is high.Detection method compares the method for testing in national standard, and the quick accurately precision of test is high.
