Summary of the invention
The purpose of this invention is to provide a kind of fast, energy consumption is low, electromagnetic impulse valve device for quick testing in serviceable life and method of testing thereof that noise is little.
For realizing above purpose, the technical solution of the utility model provides a kind of electromagnetic impulse valve device for quick testing in serviceable life, comprise Electrical heads, valve gap, diaphragm and winding-up pipe, Electrical heads is connected with valve gap, it is characterized in that valve gap is connected with glass box end cap A, diaphragm is located between valve gap and the glass box end cap A, and with winding-up pipe one end in contact, the winding-up pipe passes the other end sealing of glass box or is connected with the noise elimination mouth by nut.
Described glass box is made up of air intake opening, hex bolts, end cap A, plexi-glass tubular, O-ring seal, end cap B, hexagonal nut, the plexi-glass tubular both sides are fixed by hex bolts and hexagonal nut by end cap A and end cap B, be provided with O-ring seal between plexi-glass tubular and end cap A, the B, end cap B is provided with air intake opening.
A kind of electromagnetic impulse valve method for rapidly testing in serviceable life is characterized in that its method is:
The first step. insert source of the gas from air intake opening, connect the control power supply;
Second step. start electromagnetic impulse valve, the Electrical heads of electromagnetic impulse valve moves and makes diaphragm produce the front and back displacement, and the pipe of jetting this moment is provided with two kinds of situations:
1: winding-up pipe outlet sealing, though move behind the diaphragm, the winding-up pipe is not exitted;
2: the outlet of winding-up pipe is provided with the noise elimination mouth, though move behind the diaphragm, the winding-up pipe can only be put the gas of trace by the noise elimination mouth;
Electrical heads and diaphragm move at every turn, and air pressure is descended, and operating frequency can reach 1-2 second once, follow-on test till electromagnetic impulse valve damages, the number of times of record electromagnetic pulse valve events.
The present invention adds a glass box at the winding-up pipe, makes the stable gas pressure after the winding-up, and the diaphragm operating frequency is accelerated, and energy consumption significantly reduces, and has adopted glass box simultaneously, can diaphragm action clearly directly perceived and damaged condition.
Advantage of the present invention is that test is quick, and energy consumption is low, and noise is little, and because the proving installation volume is little, is convenient to be implemented in the test under the high and low temperature state.
