Embodiment
Below in conjunction with accompanying drawing and concrete enforcement structure of the present utility model is described further.
In Fig. 1, the centre of lower box 1 is by screw retention bearing 5, about lower box 1 hold-down support 5, there are two cylinders to insert high pressure piston 11 and low-pressure piston 14, low-pressure piston 14 link low-pressure piston bars 14, its top shaft shoulder is fixed with low pressing spring 15, and stretches out from the top center that low pressing spring is regulated tube 16 and to be hinged on the hinged commutation crossbeam 4 in bearing 5 tops; High pressure piston 11 link high-pressure piston rods 10 upwards link high pressure spring 7 successively, and regulate tube 6 top center from the high pressure spring and stretch out; High pressure piston 11 1 side fixed reset springs 8 on lower box 1, its upper end is fixed on the end of commutation crossbeam 4.Being inserted on the bearing pin that forms on the take-off lever 3 by the shift fork of being opened on it in addition of commutation crossbeam 4, take-off lever 3 is by covering on two corresponding on the upper box 2 of lower box 1 holes.
Principle of work is as follows:
1. the course of work of UHV (ultra-high voltage) output: high pressure piston 11 is subjected to the pressure effect of pretightning force effect bottom it of high-pressure piston rod 10 and high pressure spring 7, the pressure that high pressure piston 11 bottoms are subjected to is greater than the pretightning force of high pressure spring 7 and overcome the external world pulling force is set, high pressure piston 11 is pushed to the limes superiors position, high-pressure piston rod 10 is upwards exported range, and crossbeam 4 high-pressure sides that promote to commutate move upward to extreme position; Low-pressure piston 13 is subjected to the pretightning force of low-pressure piston bar 14 and low pressing spring 15 and the pressure effect of low-pressure piston bottom, because the low-pressure piston diameter is bigger, the pretightning force of the long-range low pressing spring 15 of low-pressure piston 13 bottom pressures this moment, low-pressure piston 13 is pushed upwardly extreme position, and low-pressure piston bar 14 also is pushed upwardly extreme position simultaneously.Because the special construction of junction, low-pressure piston bar 14 upper end, it produces exchange to crossbeam 4 pulling functions when the pressure ultralow pressure, crossbeam 4 low pressure ends that commutate this moment can move downward, after so commutation crossbeam 4 is upwards promoted by high-pressure piston rod 10, commutation crossbeam 4 low pressure ends move downward, the take-off lever 3 that drives low pressure end moves downward, the output pulling force.
2. the course of work of ultralow pressure output: low-pressure piston 13 is subjected to low-pressure piston bar 14 and the pretightning force of low pressing spring 15 and the pressure effect of low-pressure piston 13 bottoms, when this moment, low-pressure piston 13 base pressures were less than the pretightning force of low pressing spring 15, low-pressure piston 13 just moves downward pushes bottom dead centre to, low pressing spring 15 drives low-pressure piston bar 14 operation downwards, and pulling commutation crossbeam 4 low pressure ends move downward to the smallest limit position; Because commutation crossbeam 4 high-pressure sides move upward without limits to the crossbeam right-hand member, the take-off lever 3 that makes commutation crossbeam 4 drive left end moves downward, the output pulling force.
3. when pressure is between high pressure and the low pressure, because low-pressure piston 13 stressed skies are in low pressure, can not move downward, and the insufficient pressure of high-pressure side moves upward to drive high-pressure piston rod 10, can not make 4 motions of commutation crossbeam, commutation crossbeam 4 makes commutation crossbeam 4 be in equilibrium state under the effect of back-moving spring 8.
