Device for verifying pressure

Abstract

The invention discloses a device for verifying pressure. The device comprises a main device body, an air pressure verifying bin and a hydraulic pressure verifying bin. Signal hydraulic ends are connected with control end signals, signal sensors are in signal connection with signal motors, first, the hydraulic pressure value of the signal hydraulic ends is controlled and adjusted through the control end signals, the resistance of hydraulic telescopic rods is larger when the hydraulic pressure value is large, and becomes smaller when the hydraulic pressure value is small, air pressure or hydraulic pressure enters the air pressure verifying bin and the hydraulic pressure verifying bin to push airtight rubber under the effect of the pressure, the airtight rubber drives the hydraulic telescopicrods with the set hydraulic pressure value to retract, and when one side of either airtight rubber is connected with the signal sensors on one side of an air bleeding pipe and one side of a liquid discharging pipe, the signal motors control turning valves to turn to discharge too high air pressure or hydraulic pressure. In the design, the safety of the device is improved through automatic pressure discharging, the internal pressure of the device is also monitored in real time, and then working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pressure calibration, in particular to a pressure calibration device.
