Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline capable of intermittent heating and heat preservation. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by blowers, compressors, pumps and boilers. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0003] In cold seasons, when the ambient temperature is below 0℃, it is easy to cause the water in the pipes to freeze, which in turn causes difficulties in water supply and makes it inconvenient to use. Utility Model Content

Then, the two flanges are connected and fixed by bolts to complete the connection and fixation between the insulated pipes. The pipe plug is pulled out and water is injected into the fixed shell through the water inlet pipe. After the water fills the cavity, the pipe plug is sealed to the top of the water inlet pipe. The water temperature is monitored by the temperature sensor. When the water temperature is lower than the set threshold, the water is heated by the heater. The heated water temperature raises the temperature of the heating pipe, and then the inner pipe is heated and insulated.

[0008] Preferably, flanges are sleeved and fixed at both ends of the outer wall of the outer tube, and two adjacent outer tubes are connected and fixed by the flanges and bolts.

[0009] After the adjacent insulated pipes are butt-jointed, the two flanges are connected and fixed by bolts to complete the connection and fixation between the insulated pipes.

[0010] Preferably, sealing rings are bonded and fixed to the outer walls of both ends of the outer tube, and the inner diameter of the sealing ring is matched with the inner diameter of the inner tube.

[0011] After the pipes are butt-jointed, two adjacent sealing rings abut against each other to fill the gap at the joint and ensure the sealing of the joint.

[0012] Preferably, the outer tube and the outer wall of the insulation tube are both provided with openings at the top, and the openings are adapted to the specifications of the fixed shell.

[0013] The fixing shell is plugged and fixed to the heating tube through the opening.

[0014] Preferably, a pipe plug is inserted into the top of the water inlet pipe, and a controller is installed on the outer wall of one end of the water inlet pipe, and the temperature sensor and the heater are electrically connected to the controller.

[0016] Preferably, a cavity is provided between the outer wall and the inner wall of the heating tube, water is injected into the cavity, and the cavity is communicated with the fixed shell.

[0017] After water is injected into the fixed shell, the water fills up the cavity, the water is heated by the heater, the heating pipe is heated by the water temperature, and then the inner pipe is heated and kept warm.

[0018] The beneficial effects of the utility model are:

[0019] Two adjacent pipes are connected and fixed by a flange, and water is injected into the fixed shell through the water inlet pipe after the pipe plug is pulled out. After the cavity is filled with water, the pipe plug is sealed to the top of the water inlet pipe. The water temperature is monitored by a temperature sensor. When the water temperature is lower than the set threshold, the water is heated by a heater, and the heated water temperature raises the temperature of the heating pipe, thereby heating and insulating the inner pipe. This effectively solves the problem in the prior art that in cold seasons, when the ambient temperature is below 0°C, the water in the pipe is easily frozen, thereby causing difficulties in water supply and inconvenience in use.
