Abstract

The invention discloses a special anti-freezing device for a crude oil pressure gauge. The device comprises a pressure gauge, a mounting frame and first display glass are arranged on the pressure gauge; the bottom end of the pressure gauge is connected with a connecting pipe, a piston is arranged in the connecting pipe, the top end of the connecting pipe is filled with an anti-freezing solution, the anti-freezing solution is located on the upper side of the piston, a reset device is arranged at the bottom end of the piston, a protective shell is detachably installed on the outer side of the pressure gauge, and second display glass is arranged on the protective shell. The top end of the connecting pipe is filled with the anti-freezing solution, when the pressure gauge works, crude oil extrudes the piston to drive the anti-freezing solution to enter the spring pipe of the pressure gauge, liquid such as water is prevented from directly entering the spring pipe, the liquid such as water isprevented from freezing in the spring, and therefore the spring pipe and the pressure gauge can be prevented from being frozen.

Description

technical field [0001] The invention relates to the technical field of antifreeze for pressure gauges, in particular to a special antifreeze device for crude oil pressure gauges. Background technique [0002] Pressure gauges are widely used in oil and water pipelines in oil fields. Due to the vast territory of our country, many oil fields are located in the northeast, northwest and other alpine regions, and the pressure gauges installed on the open-air pipelines are often damaged by freezing in winter. The main reason for the pressure gauge to be frozen is that when the medium water or oil in the oil and water pipeline enters the pressure gauge, the medium freezes due to the low external ambient temperature, causing the spring tube and the pressure gauge in the pressure gauge to be frozen. , once the pressure gauge is damaged by freezing, it will affect the normal oil recovery operation, so it needs to be improved. Contents of the invention [0003] The purpose of the pre...
