Embodiment
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, according to pressure switch detection device of the present invention, comprising: forcing pump 10, pressure switch detection path, pressure limiting valve 30 and control system.Pressure switch detection path is connected with the output terminal of forcing pump 10, and for installing testing pressure switch 21, pressure switch detection path comprises the pressure-detecting device 22 between the output terminal being arranged on testing pressure switch 21 and forcing pump 10; Pressure limiting valve 30 is connected with the output terminal of forcing pump 10, for the pressure of limiting pressure switch detection path, prevents pressure excessive and causes potential safety hazard; Control system comprises indicating device 41, indicating device 41 is electrically connected with testing pressure switch 21, be used to indicate the duty of testing pressure switch 21, preferably, indicating device 41 adopts pilot lamp, convenient and simple, and the duty of testing pressure switch 21 can be judged intuitively by the extinguishing of pilot lamp.
Pressure switch detection device of the present invention, by arranging forcing pump 10 and pressure switch detection path provides pressure to testing pressure switch 21, the indicating device 41 of control system indicates the duty of testing pressure switch 21, in test process, by pressure-detecting device 22 testing pressure switch 21 duty change time force value and standard value contrast, can judge whether testing pressure switch 21 normally works, improve reliability, prevent subsequent production from breaking down.Pressure switch detection device structure of the present invention is simple, easy to operate.
Usually, pressure medium can adopt water or air, and in the more preferably embodiment of invention, pressure medium adopts water, close with the actual applying working condition of testing pressure switch 21, and the convenient sealing property judging testing pressure switch 21.Preferably, in order to improve the cleanliness factor of pressure medium, pressure switch detection device also comprises filtration unit 50, the inlet end of filtration unit 50 is connected with the output terminal of forcing pump 10, pressure switch detection path is connected with the output terminal of filtration unit 50, by arranging filtration unit, removes the impurity in water, prevent testing pressure switch 21 or miscellaneous part from blocking and affecting test structure, improve the accuracy of test.Preferably, filtration unit 50 adopts RO filter flask, easy to use, and strainability is good.
Preferably, pressure switch detection path also comprises solenoid valve 23, and solenoid valve 23 is arranged between pressure-detecting device 22 and testing pressure switch 21, in replacing testing pressure switch 21 process, can shut electromagnetic valve 23, and prevent the aqueous reflux in connecting line.Usually, connecting line adopts PE pipe, and easy to connect, soft or hard is suitable.
Preferably, pressure switch detection path also comprises retaining valve 24, and retaining valve 24 is connected with the endpiece of testing pressure switch 21, also can prevent in inspection disassembly process, the aqueous reflux in connecting line.
Preferably, pressure switch detection path also comprises flow control valve 25, flow control valve 25 is connected with the endpiece of retaining valve 24, the flow of flow control valve 25 is set, the pressure release speed of testing pressure switch 21 can be regulated, prevent testing pressure switch 21 rapidly pressure release and the pressure of caused by inconvenient judgment pressure-detecting device 22 when measuring pressure switch 21 resets, cause reseat pressure to detect inaccurate problem.
