Abstract

The invention discloses a digital pressure gauge, and belongs to the technical field of measuring equipment. The digital pressure gauge comprises an assembly box, the bottom of the assembly box is communicated with an inner core pipe, the outer side wall of the inner core pipe is fixedly provided with a connecting flange, the top of the assembly box is provided with a pressure assembly, the top of the pressure assembly is movably connected with a protection assembly, and the inner cavity of the assembly box is movably connected with a clamping part. In the invention, a pressure medium can be collected and drained to a bottom pressure relief pipe through a liquid storage tank in the inner cavity of a liquid collection tank shell and enters the protection assembly, so that the front end of a protection shell and a pressure gauge body are prevented from being damaged due to impact, and emergency protection after the pressure gauge body is broken due to the fact that the pressure medium exceeds a threshold value is realized, impact damage caused by direct splashing of a pressing medium to the external environment is avoided, the emergency response time during leakage is provided, emergency evacuation or first-aid repair rescue of workers is facilitated, and then the use protection safety can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment, in particular to a digital pressure gauge. Background technique [0002] A pressure gauge refers to an instrument that uses an elastic element as an elastic sensitive element to measure and indicate environmental pressure. It is widely used and is mostly used in pipe networks, transmission attacks, and convenient measurement. The existing digital pressure gauge converts elastic deformation into electrical signals through microcircuits. Pressure gauges on display. [0003] Chinese patent CN107478373A discloses an antifreeze pressure gauge, including a gauge head, the bottom of the gauge head is fixedly connected with a pressure introduction tube, the surface of the pressure introduction tube is covered with a protective cover, and the protective cover includes a housing, The inner cavity of the housing is provided with antifreeze, one side of the housing is provided with a heating wir...
