Description

Electric tracing composite water supply pipe for constructional engineering

Technical Field

The utility model belongs to the technical field of liquid conveying pipeline, concretely relates to building engineering is with compound feed pipe of electric tracing.

Background

The existing water supply pipeline anti-freezing and heat-insulating measures comprise the following steps:

1. the pipeline is dressed with a hat, and the exposed water pipe is wrapped by heat-insulating materials such as cotton-linen fabrics, plastic foams and the like, so that the heat loss of the pipeline is reduced. In severe cold weather, the pipeline is extremely easy to be frost-cracked.

2. And heating the pipeline to offset the heat loss of the pipeline. The electric tracing band is wound on the insulated pipeline and fixed, and then the electric tracing band is protected by using an insulation material. The electric tracing band can effectively solve the problem of heat loss of the pipeline by using the electric tracing band, but has strict requirements on the construction of the electric tracing band, if the construction method is not standard, the electric tracing band is easy to generate uneven heat or not generate heat on the pipe wall, the heat preservation and anti-freezing effects are lost, the construction process is complicated, and the appearance is bloated and coarse; the outer layer of the electric tracing band must adopt an external heat preservation measure, and the heat preservation layer is easy to damage.

SUMMERY OF THE UTILITY MODEL

The drawback to prior art existence, the utility model aims at providing a construction installation is convenient, and the thermal insulation performance that generates heat is reliable and stable, synthesizes the cost and hangs down to the clean and tidy pleasing to the eye building engineering electric heat tracing composite feed pipe is used to the outward appearance.

The purpose of the utility model is realized with the following mode:

an electric tracing composite water supply pipe for constructional engineering is provided with an insulated water pipe, PTC heating materials, an insulating layer, a metal net and a heat preservation outer sleeve in sequence from inside to outside, and two electric heating leads (3) are arranged between the insulated water pipe and the PTC heating materials and symmetrically arranged on two sides of the insulated water pipe.

The insulating water pipe is a plastic pipe.

The insulating water pipe is a random copolymerization polypropylene pipe.

The electric heating wire is a zinc-plated copper wire.

The insulating layer is a rubber insulating layer.

Compared with the prior art, the utility model discloses compound electric heat tracing material and water pipe tubular product and become an organic whole, promoted pipeline heat retaining performance that prevents frostbite winter, and the outward appearance is clean and tidy pleasing to the eye, not too fat, clean, environmental protection, energy-conservation, heating heat preservation temperature easily controls, effectively reduces life cycle's maintenance cost, has good economic benefits and social.

Detailed Description

As shown in fig. 1 and fig. 2, an electric tracing composite water supply pipe for construction engineering is provided with an insulated water pipe 1, a PTC heating material 2, an insulating layer 4, a metal mesh 5 and an outer sleeve 6 with a heat preservation function in sequence from inside to outside, electric heating leads 3 are arranged between the insulated water pipe 1 and the PTC heating material 2, the two electric heating leads 3 are symmetrically arranged at two sides of the insulated water pipe 1, and the electric heating leads 3 are preferably galvanized copper leads; insulating layer 4 is the rubber insulation layer, insulating water pipe 1 chooses for use the plastic tubing, preferably random copolymerization polypropylene pipe (PPR pipe), according to the operation environment, can also choose for use PVC pipe, PE pipe, can also choose for use to mould compound metal pipe, mould the outmost plastics material of compound metal pipe for insulating, prevent with electric heat wire direct contact.

The random copolymerization polypropylene pipe (also called PPR pipe) is selected as the inner pipe of the electric heat tracing composite water supply pipe, and has the advantages of energy and material saving, environmental protection, light weight, high strength, stable performance, heat resistance, heat preservation, corrosion resistance, smooth inner wall, no scaling, safe and reliable pipeline system, no penetration, long service life and the like.

Two galvanized copper wires are laid on the outer wall of the PPR pipe, and PTC heating materials are filled between the galvanized copper wires, so that the PPR pipe is provided with a good insulating material, an insulating layer is not required to be arranged on the outer side of the PPR pipe, and the PTC heating materials are typical semiconductor resistors with temperature sensitivity. The PTC ceramic heating element is composed of a PTC ceramic heating element and an aluminum tube. The PTC heating material has the advantages of small thermal resistance, quick heating, stable temperature and low energy consumption. The safety device has the outstanding characteristics that the surface of an electric heating tube heater does not become red under any application condition, so that potential safety hazards such as scalding and fire disasters are avoided.

The rubber insulating layer 4 is laid on the outer side of the PTC heating material 2, the rubber insulating layer has waterproof and heat preservation effects, the metal mesh 5 is wrapped on the outer side of the rubber insulating layer 4, the toughness and strength of the whole composite pipe are improved due to the metal layer, and the rigidity of the pipe is improved due to the outer sleeve wrapped on the outer side of the metal mesh.

The utility model discloses a compound feed pipe of electric tracing for building engineering of preparation, the outward appearance is clean and tidy pleasing to the eye, with the compound integrative structure that becomes of tracing material and tubular product, has promoted the heat preservation effect that prevents frostbite in winter of pipeline, effectively reduces the life cycle maintenance cost of compound feed pipe, has good economic benefits and social.
