Fig. 2 is the wave washer fatigue strength tester structural representation of a kind of embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, by the following examples, and by reference to the accompanying drawings, wave washer fatigue strength tester of the present utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1-Fig. 2, a kind of wave washer fatigue strength tester, comprising: reduction valve 100, solenoid directional control valve 200, cylinder 300, piston and ring flange 400.
Piston is placed in the inside of cylinder 300, therein slippage; Ring flange 400 is placed in the outside of cylinder 300, is connected with piston; Wave washer 800 be placed in ring flange 400 under.
Air pump is connected with cylinder 300, in the middle of the extensive existence of air pump and workshop, as the power source in workshop, by gas transfer power, by the power of air pump output by gas transfer to cylinder 300, the pressure test that can carry out repeatedly wave washer 800, thereby the serviceable life of learning wave washer 800.
During gas process solenoid directional control valve 200, solenoid directional control valve 200 periodic variations flow to the direction of cylinder 300 gases, cylinder 300 is done reciprocal piston movement according to the power of gas transfer, ring flange 400 under the drive of cylinder 300 to extruding wave washer 800, carry out pressure test repeatedly, thereby reach test objective.
Preferably, the cylinder 300 of the present embodiment adopts single-acting cylinder, makes ring flange 400 lift and leave wave washer 800 by spring under the effect of elastic force, has reduced cost, and has made structure simpler.
Preferably, the solenoid directional control valve 200 of the present embodiment adopts direct driving type electromagnetic reversal valve, and direct driving type electromagnetic structure of reversing valve is simple, stable performance.
Preferably, as a kind of embodiment wherein, solenoid directional control valve 200 impulse meter 500 of also having contacted, cylinder 300 completes a pressure test impulse meter 500 and accumulates once.By arrange impulse meter 500 clearly wave recording packing ring 800 after how many times pressure test, be damaged.
Preferably, the utility model also comprises the time relay 600, and the commutation function of solenoid directional control valve 200 is played to time-lag action, facilitates time setting, makes device operation more stable.
