Abstract

The invention discloses a pressure gauge for a high pressure vessel. An outer shell is included, a top of the outer shell is connected with a gauge head; a threaded part is arranged at a bottom of theouter shell; a diaphragm cavity is arranged in the outer shell; a diaphragm is fixed in the diaphragm cavity; a through hole is arranged in a center of the diaphragm; a jacking inner core is fixed onan edge of a top surface of the through hole; an outer side of the jacking inner core is connected with a jacking outer sleeve; the jacking outer sleeve is connected with the gauge head; a pluralityof first elastic sheets are fixed on the edge of the bottom surface of the through hole; a bottom end of each first elastic sheet is obliquely arranged towards an axial direction of the through hole;and a sealing ring is fixed to the bottom of the outer shell, a piston rod is movably inserted into an inner side of the sealing ring, first sliding grooves in one-to-one correspondence with the firstelastic pieces are arranged in the edge of the top surface of the piston rod, a cylindrical lifting pin is arranged in a center of the top surface of the piston rod, and a spherical protrusion is arranged on the top surface of the cylindrical lifting pin. Defects in the prior art can be overcome, and measurement accuracy of a low-pressure area is improved while safety of the pressure gauge is guaranteed.

Description

technical field [0001] The invention relates to a metering and testing device, in particular to a pressure gauge for a high-pressure container. Background technique [0002] The pressure gauge is a measuring device used to detect the pressure. In order to ensure the safety of the high-pressure vessel, it is necessary to monitor the pressure inside the high-pressure vessel by installing a pressure gauge. However, for the safety and durability of the existing pressure gauges under high-pressure working conditions, the measurement accuracy in the low-pressure area will be affected, so that the effective measurement range of the pressure gauge is limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressure gauge for high-pressure containers, which can solve the deficiencies of the prior art and improve the measurement accuracy of the low-pressure area while ensuring the safety of the pressure gauge. [0004] ...
