Abstract

The invention discloses a pressure gauge for a high-pressure container, which comprises an outer casing, the top of the outer casing is connected with a meter head, the bottom of the outer casing is provided with a threaded part, the outer casing is provided with a diaphragm cavity, and a diaphragm is fixed in the diaphragm cavity. The center of the diaphragm is provided with a through hole, the top edge of the through hole is fixed with a jacking inner core, the outer side of the jacking inner core is sleeved with a jacking jacket, the jacking jacket is connected with the meter head, and several holes are fixed on the edge of the bottom surface of the through hole. The first shrapnel, the bottom end of the first shrapnel is inclined towards the axial direction of the through hole, the sealing ring is fixed on the bottom of the outer casing, the inner side of the sealing ring is movably inserted with the piston rod, and the top surface edge of the piston rod is provided with the first The shrapnels are one-to-one corresponding to the first chute, the center of the top surface of the piston rod is provided with a cylindrical ejector pin, and the top surface of the cylindrical ejector pin is provided with a spherical protrusion. The invention can improve the deficiencies of the prior art, and improves the measurement accuracy of the low-pressure area while ensuring the safety of the pressure gauge.

Description

Technical field [0001] The present invention relates to a measuring and testing equipment, in particular for a gauge pressure vessel. Background technique [0002] Pressure gauge for detecting the pressure of the metering device, in order to ensure the safety of the pressure vessel, the need for real-time monitoring of the pressure inside the pressure vessel by installing a pressure gauge. However, the conventional high-pressure gauge for the safety and durability of the conditions, the low pressure region will affect the measurement accuracy decreases, so that the effective measurement range of less gauge. Inventive content [0003] The present invention is to solve the technical problem of providing a container for a high pressure gauge, it is possible to solve the deficiencies of the prior art, the pressure gauge to ensure safety while improving the measurement accuracy of the low pressure region. [0004] In order to solve the above technical problems, the technical solution...
