Abstract

The invention relates to a pressure measuring device, which is used for a pressure container, wherein the pressure container comprises a pressure measuring hole. The pressure measuring device comprises a meter body, a connecting assembly and a pushing assembly, wherein the meter body comprises a pressed part, the connecting assembly comprises a first connecting piece and a second connecting piece, the first connecting piece is in threaded connection with the pressure measuring hole, the second connecting piece is in threaded connection with the pressure measuring hole and is connected with the meter body, and the pushing assembly is movably arranged on the connecting assembly in a penetrating mode. In the prior art, the internal threads of an assembly connecting hole drilled in a pressure container is poor in construction quality and bad in use habits of users, so that a pressure gauge is easily pushed by pressure of a fluid in the pressure container so as to be reversely sprayed away from the pressure container, andsafety doubts are caused in use. According to the invention, the problems in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of pressure measurement, in particular to a pressure measurement device. Background technique [0002] Pressure gauges are often used in pressure vessels such as gas cylinders, pipes, valve bodies, etc., to display the pressure change inside the container in a numerical form, which is convenient for users to monitor the safety status, or to know whether the fluid inside the container needs to be replenished, etc. Among them, the pressure gauge is usually combined with the pressure vessel by means of screw connection, in order to have the advantages of easy assembly and disassembly. [0003] However, due to the poor construction quality and poor user habits of the internal thread of the assembly hole drilled on the pressure vessel, the pressure gauge is likely to spray back from the pressure vessel due to the pressure of the fluid in the pressure vessel. lead to safety concerns in use. [0004] Therefore, i...
