Abstract

The invention relates to an automatic air-off system for an air gauge. An installation plate is fixedly arranged on a support, a plurality of mechanical valves of the air gauge are fixedly installed on the lower surface of the installation plate, lever seats with the same number as the mechanical valves are fixedly positioned on the lower surface of the installation plate on the side of the mechanical valves, each lever seat is provided with a lever, the middle section of each lever is hinged on the lever seat through a pin shaft, one end of each lever is matched with contact points of the mechanical valves, air gauge hanging plates are fixed on the upper surfaces of the other ends of the levers, and balance weights are fixed on the levers on the inner sides of the air gauge hanging plates. The automatic air-off system can automatically cut off air and is simple in structure, convenient in installation, convenient in adjusting the balance weights according to weight of gauges, suitable for various air gauges, simple in operation, small in occupancy and suitable for various occasions.

Description

technical field [0001] The invention relates to an auxiliary tool for a pneumatic gauge, in particular to an automatic air cut-off system for a pneumatic gauge. Background technique [0002] In the existing products, the automatic air shut-off system is generally a seat type mechanical valve air shut-off system, which is mainly composed of a placement seat, a counterweight and a mechanical valve. Due to the uncertainty of the weight of the pneumatic gauge, it is difficult for this mechanism to adjust the weight of the counterweight, resulting in unstable operation of the air cut-off system. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an automatic gas cut-off system for pneumatic gauges that is simple in structure, easy to install, can adjust the counterweight according to the weight of the gauge, and can adapt to various pneumatic gauges. [0004] According to the technical solution ...
