Abstract

The invention discloses a digital pressure gauge, belonging to the technical field of measuring equipment, comprising an assembly box, the bottom of the assembly box is connected with an inner core tube, and the outer wall of the inner core tube is fixedly installed with a connecting flange, and the top of the assembly box is provided with a There is a pressure component, and the top of the pressure component is movably connected with a protective component, and the inner cavity of the assembly box is movably connected with a clamping part. In the present invention, the pressure medium can be collected and drained to the bottom pressure relief pipe and enter the protective assembly through the liquid storage tank in the inner cavity of the sump shell, so as to avoid damage to the front end of the protective shell and the pressure gauge body due to impact. It is conducive to the realization of emergency protection after the pressure gauge body ruptures due to the pressure medium exceeding the threshold value, avoids the impact damage caused by the direct splash of the pressure medium to the external environment, provides emergency response time in case of leakage, and is conducive to the emergency evacuation or emergency repair of the staff. Rescue, and then can effectively improve the use of protection security.

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...
