Abstract

The invention relates to an anti-freezing pressure tapping pipe and discloses an anti-freezing pressure tapping pipe provided with a heating pipe. The anti-freezing pressure tapping pipe provided with the heating pipe aims to solve the problem that an existing pressure tapping pipe can be frozen to be blocked when used in severe cold areas. The anti-freezing pressure tapping pipe provided with the heating pipe comprises a pipe body, the heating pipe, a heat insulation layer and a liquid pipeline, wherein the heating pipe is arranged outside the pipe body, the heat insulation layer is arranged outside the heating pipe, the lower end of the pipe body is vertically connected with the liquid pipeline, a connecting pipe is connected with the upper end of the pipe body through a flange and is fixed through a bolt, a sealing gasket is arranged between the pipe body and the connecting pipe, a ball valve is connected to the connecting pipe, a pressure gauge is arranged at the topmost end of the device, phase-change media are arranged in the heating pipe, and a positioning ring is arranged outside the heat insulation layer. According to the anti-freezing pressure tapping pipe provided with the heating pipe, external energy resources are not needed, the electrifying difficulty of a traditional pressure tapping pipe is overcome, the heating effect is achieved, freezing and blocking of the pressure tapping pipe are effectively prevented, energy resources are saved, and measurement of the pressure of liquid in the pipeline is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipeline pressure measuring devices, in particular to an antifreeze type pressure taking tube with a heating tube. Background technique [0002] The pressure taking tube is used to measure the relative pressure of the liquid and is connected to the open tube of the measured liquid. It can be used to monitor the dam body seepage line, osmotic pressure, groundwater level and seepage around the dam, etc. It is widely used in different fields, such as petroleum, chemical industry, engineering machinery manufacturing, coal mine, shipbuilding, aviation, automobile, industrial control, medical equipment and other industries. It is widely used in the measurement of liquid pressure in pipes. Most of the pressure taking tubes currently used are electric heating, that is, electric heating tape is wound on the pressure taking tube, and electric energy is used to heat the pressure taking tube, but this kind of pressu...
