Further, in the pedestal, coupling shaft can move up and down in inner thread sleeve and middle pedestal in the middle of said coupling shaft upper end was arranged in.
Further, also comprise solenoid valve to be measured, said solenoid valve is located on the upper surface of middle pedestal, and armature is covered with within it, and the upper surface of armature is parallel with the interior lower surface of solenoid valve.
Further, said stress test sensor is connected with a display device.
A kind of solenoid valve stress test method, its operation steps is:
The first step is installed in the solenoid valve shell on the middle pedestal, and the upper surface of armature is parallel with the interior lower surface of solenoid valve;
Second step is after placing the elastomeric pad of different-thickness between coupling shaft and the inner thread sleeve, again with coupling shaft and inner thread sleeve locking, i.e. gap length between the lower surface in scalable armature upper surface and the electromagnet;
The 3rd step, with the upper surface position of dial gauge measurement armature, measure the interior lower surface position of magnet valve again, draw the gap between two surfaces, behind the elastomeric pad of placement different-thickness, the gap between the two dwindles gradually, keeps the zero stand-off until the two;
The 4th step, corresponding different clearance size, and read the numerical value of the suffered pulling force from coupling shaft of stress test sensor through display device, can obtain the relation that the solenoid valve electromagnetic force changes with magnet and armature clearance.
Beneficial effect of the present invention is: after solenoid valve to be measured is installed on the proving installation of the present invention, thereby through regulating the gap between solenoid valve and the armature face placing the different-thickness elastomeric pad between inner thread sleeve and the coupling shaft, thereby change the size of the attractive force between the two; This force transmission is given the stress test sensor; Pass to display device again, note the stress intensity under the different gap, can be through calculating the relation that the solenoid valve electromagnetic force changes with magnet and armature clearance; Therefore; Compare with prior art, apparatus structure of the present invention is simple, easy operating; This method of testing step is few, is easy to test out at short notice the data that need.
