Problems solved by technology

For this kind of pressure gauge, if the pressure of the measured medium continues to increase, the piston will go up all the time, and the antifreeze hydraulic oil will exert pressure on the inside of the pressure gauge, and make the pointer continuously move towards the maximum range until the pointer moves to the maximum range. When the pressure is too high, the pointer exceeds the maximum range or breaks, which eventually leads to damage to the pressure gauge

Abstract

The invention relates to a component of a pressure gauge and discloses an anti-freezing pressure gauge short casing joint. The anti-freezing pressure gauge short casing joint comprises a shell; a short casing joint inlet is formed at one end of the shell; a short casing joint outlet is formed at the other end of the shell; a driving rod is arranged in the shell; one end of the driving rod, which is far away from the short casing joint inlet, and the shell form a first hollow cavity; a through hole communicated with the short casing joint inlet and the first hollow cavity is formed in the driving rod; one end of the driving rod, which is adjacent to the short casing joint inlet, and the shell form a second hollow cavity; the driving rod in the first hollow cavity and the second hollow cavity are in slide connection with the shell; the second hollow cavity is communicated with the short casing joint outlet; and the second hollow cavity and the short casing joint outlet are filled with anti-freezing hydraulic oil. With the anti-freezing pressure gauge short casing joint of the invention adopted, the problem of damage to the pressure gauge when the pressure of a measured medium is excessively large can be solved, and the pressure gauge will not be damaged when pressure is excessively large.

Description

technical field [0001] The invention relates to a component of a pressure gauge, in particular to a short circuit of an antifreeze pressure gauge. Background technique [0002] The short connection of the pressure gauge refers to the connection compensation between the pressure gauge and the measured medium pipeline, which is used to connect the connection between the inside of the pressure gauge and the inside of the pipeline. [0003] The Chinese patent No. is CN201420698953.5, which discloses a short-connected anti-freeze pressure gauge. The external thread connected to the valve; the cavity of the housing has a piston built in, and two parallel annular grooves are opened on the side wall of the piston, and sealing rubber rings are fixed in the two annular grooves; the screw hole at the upper end of the housing A sealing gasket is fixed inside. For this kind of pressure gauge, if the pressure of the measured medium continues to increase, the piston will go up all the ti...
