Abstract
Description
Technical Field
[0001] The utility model relates to the field of water pipe technology, in particular to a coated pipe with a heating function. Background Art
[0002] Pipes are essential materials for construction projects. Commonly used ones include water pipes, drainage pipes, gas pipes, heating pipes, electrical conduits, rainwater pipes, etc.
[0003] The water pipes in the prior art are generally not well suited for use in severely cold regions. Due to the low temperature in severely cold regions, the water pipes are easily frozen, resulting in obstructed water flow and even complete blockage of the pipes.
[0004] A published patent (publication number: CN103438564A) relates to an electrically heated water pipe. The pipe comprises an inner and outer wall, with a reinforcement layer interposed between the two layers. An electric heating wire is disposed within the inner wall. A temperature sensor, positioned close to the outer wall, measures the wall temperature and controls the heating wire's circuit. An electrical plug, electrically connected to the heating wire and located outside the pipe, is located at the other end. Advantages include effectively preventing the pipe from freezing and cracking, and conserving energy.
[0005] However, the heating wire provided in the prior art is arranged along the axial direction of the water pipe, and its overall wrapping property is poor, resulting in less than ideal heating or heat preservation effects. Utility Model Content
[0006] The purpose of the present invention is to provide a cladding pipe with a heating function to solve the problems raised in the above background technology.
[0007] To achieve the above objectives, the present invention provides the following technical solutions:
[0008] A coated pipe with a heating function, comprising a pipe and a coating layer covering the outer side of the pipe, wherein an inner groove is formed on the outer wall of the pipe, and two inner grooves are arranged in parallel and both are arranged in a spiral shape;
[0009] It also includes a heating unit, which is embedded in the embedded groove.
[0010] The coated pipe with heating function as described above: the heating unit includes a heating tape, and the heating tape is connected to the connection terminal installed on the outside of the coating layer.
[0011] The above-mentioned cladding tube with heating function: the depth of the embedded groove is 0.2 mm.
[0012] For the above-mentioned clad pipe with heating function, the distance between the two embedded grooves is 200-300 mm.
[0013] The coated pipe with heating function as described above: the shape of the coating layer is the same as that of the pipe.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The coating is made of wear-resistant heat-insulating material, which can reduce the heat loss of the heating unit during the heating process to a certain extent. The parallel embedded grooves increase the heating range and can reduce the power output of the heating unit to a certain extent.
[0016] The utility model provides a coated pipe with a heating function, which effectively solves the problem of serious heat loss when liquid passes through the pipe, and realizes the insulation or heating effect of the liquid in the pipe; secondly, it can eliminate the need for freezing of the liquid in the pipe due to low external temperature, which causes the pipe to rupture or the inability to supply liquid. It can be used in residential houses, factories and industrial buildings, etc., and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.
[0021] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
[0022] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.
[0023] See also Figures 1 and 2In an embodiment of the utility model, a coated pipe with a heating function includes a pipe 3 and a coating layer 1 coated on the outside of the pipe 3, and is characterized in that an embedded groove 5 is formed on the outer wall of the pipe 3, and two embedded grooves 5 are arranged in parallel and are both spirally arranged; it also includes a heating unit, and the heating unit is embedded in the embedded groove 5.
[0024] In this embodiment, the pipe 3 can be PVC, PE or iron pipe, etc. After the pipe 3 is formed, the heating unit is wrapped around the outside of the pipe 3, and then the coating layer 1 is covered on the outside of the pipe 3 to limit the heating unit. The coating layer is made of wear-resistant and heat-insulating material, which can reduce the heat loss of the heating unit during the heating process to a certain extent. The parallel embedded grooves 5 set increase the heating range and can reduce the power output of the heating unit to a certain extent.
[0025] The present embodiment provides a coated pipe with a heating function, which effectively solves the problem of severe heat loss when liquid passes through the pipe, and realizes the insulation or heating effect of the liquid in the pipe; secondly, it can eliminate the need for freezing of the liquid in the pipe 3 due to low external temperature, which causes the pipe 3 to rupture or fail to supply liquid. It can be used in residential houses, factories, industrial buildings, etc., and has a wide range of applications.
[0026] Furthermore, the heating unit includes a heating tape 4, which is connected to a terminal 2 installed on the outside of the covering layer 1. The terminal 2 is used to connect a power supply unit and a controller to realize current supply and on-off control of the heating tape 4.
[0027] Preferably, the depth of the embedded groove 5 is 0.2 mm, and the spacing between the two embedded grooves 5 is 200-300 mm. Of course, the depth and spacing of the embedded grooves 5 can be selected according to actual needs. The above is a preferred embodiment given by the present utility model.
[0028] Furthermore, the shape of the coating layer 1 is the same as that of the tube 3. For example, when the tube 3 is cylindrical, the coating layer 1 is also cylindrical. When the tube 3 is square, the coating layer 1 is also square, thereby effectively ensuring that the coating thickness of the coating layer 1 on the outside of the tube 3 is basically the same.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
