Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described further.
As shown in Figure 1 and Figure 2, a kind of natural pressure force checking device, including piston cylinder 5, piston clamp 4, casing 3, piston 8, pressure transmission rod 9, described piston cylinder 5 is connected by clamping screw 2 with piston clamp 4 and casing 3, piston cylinder 5 top has gas inlet hole 6 and connects pressure guiding pipe 7, and piston clamp 4 has passage 10；Casing 3 lower end is provided with high-voltage trigger 15 and low pressure trigger 14, high-voltage trigger 15 and low pressure trigger 14 and is made up of one piece of insulation slide block being provided with spaced electrode 17 respectively；Casing 3 lower end has a vertical slot, and high-voltage trigger 15 and low pressure trigger 14 are placed in vertical slot；One end of described pressure transmission rod 9 connects piston 8, and the other end is bolted one piece of trigger board being made up of conductive material 1, balance adjustment nut 12 and pressure balance spring 11 and is arranged on the middle part of pressure transmission rod 9；Balance adjustment nut 12 is connected by the external screw thread being opened in pressure transmission rod 9 with pressure transmission rod 9；The level of stretch of pressure balance spring 11 can be changed by spin balancing adjusting nut 12, and then regulating piston 8 reaches high limits pressure and the position of lower bound pressure activated point；By the trigger position of the position-adjustable high-low pressure of slip high-voltage trigger 15 and low pressure trigger 14, and then regulate pressure upper limit value and the threshold pression value of the alarm signal of output.
High-voltage trigger 15 and high-voltage radio communication module 16 connect, and low pressure trigger 14 is all connected with low pressure wireless communication module 13, the trigger board 1 i.e. switch of circuit, when trigger board 1 contacts with trigger, then and circuit communication, produce corresponding trigger alarm signals.
Under normal circumstances, pressure balance spring 11 is in extended state, and by pressure guiding pipe 7 by appendix and piston cylinder 5 UNICOM, the gas pressure in piston cylinder 5 acts on piston 8.The elastic force of pressure balance spring 11 is acted on by balance adjustment nut 12 and acts on to piston 8 in pressure transmission rod 9, now piston 8 and pressure transmission rod 9 stress are in poised state, the lower end trigger board 1 of pressure transmission rod 9 is between high-voltage trigger 15 and low pressure trigger 14, high-voltage radio communication module 16 and low pressure wireless communication module 13 are in open circuit, do not send alarm signal.
