SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a pressure measuring device structure to prior art's not enough, thereby it is great to have solved the impact that prior art piston both sides received the thorax pressurized gas, has aggravated the wearing and tearing of piston with the body, has increaseed the impact for measurement accuracy is not accurate enough problem.
The utility model discloses an adopt following technical scheme to realize:
the pressure measuring device structure comprises a pressure measuring device body, a piston, a spring and a screw plug, wherein a through hole is radially formed in the pressure measuring device body, the piston is arranged in the through hole, and the spring is arranged between the pressure measuring device body and the piston.
Preferably, the through hole comprises a screw plug hole and a piston motion hole, the aperture of the upper half section of the piston motion hole is larger than the aperture of the end of the lower half section, the piston is located at a flange at one end of the piston motion hole of the upper half section, a spring is arranged at a gap between the piston and the piston motion hole of the upper half section, one end of the spring is fixed at the flange section of the piston, and the other end of the spring is fixed at the bottom of the piston motion hole of the upper half section.
Compared with the prior art, the utility model discloses following profitable technological effect has:
the design is that a spring is added between the piston and the body, and the length of the piston extending out of the body is adjusted, so that the impact of the pressure gas on two sides of the piston is reduced, and the abrasion between the piston and the body is reduced; the piston is in contact with the pressure measuring copper column, so that impact is reduced; under the effect of spring, piston and pressure measurement copper post contact each other, have reduced the stroke of piston motion in this body, reduce the stroke of piston to 1.2mm by 4.5mm, original pressure measurement device's life improves to 500 times by 300 times. The measuring error caused by impact is reduced, and the accuracy of the pressure measuring result is improved.
