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.
