Description

A double bonding hose for heating

The present invention relates to a heating structure having a double structure, and more particularly, to a heating hose having a double structure that can withstand high temperature hot water heat supplied from a boiler, and has excellent elasticity and improved workability.

In general, hot water heated in a boiler is circulated by directly supplying a pipe hose through a circulation pump.

In addition, the piping material for supplying hot water for this purpose is constructed by using a metal pipe and a synthetic resin pipe arranged on the floor or a prefabricated panel.

On the other hand, the metal pipes used for heating piping are mainly used copper pipes that do not have a concern of corrosion, and as the synthetic resin pipes are selected and used as the Excel pipe.

However, when the copper pipe is used for heating piping, the heat conductivity is high, while the manufacturing cost increases and the trouble of welding the pipe during construction occurs, resulting in a poor constructionability.

In addition, when the copper pipe as described above is used for heating piping, the inside of the pipe is corroded by flowing hot water, etc., as well as forming rust and reducing the service life, and additionally incurring additional repair costs. In addition to the problem that the thickness of the panel to be applied to the prefabricated panel, there is a problem that a separate circulation pipe must be installed separately for construction.

In addition, there is a problem in that the various materials contained in the water react with each other to form scales in the conventional heating hose, thereby obstructing the flow of water.

The present invention has been made in order to solve the above problems, it is configured to withstand the high temperature hot water supplied from the boiler and excellent elasticity, heat transfer efficiency is improved, and prevents rust and scale generated inside the pipe It relates to a heating hose having a double structure configured to be able to.

In order to achieve the above object, the present invention forms a polybdenum layer having an activator Rosin on the inner circumferential surface of a hot water pipe formed of a thermoplastic thermoplastic elastomer (TPV) of rubber material to have a double structure of excellent heat resistance and weather resistance Is to provide.

When the heating hose made as described above is used in connection with the boiler, the thermal conductivity and the life of the hose is extended, and when the heating hose of the present invention is used, the amount of oil and electricity required for heating the boiler is reduced by that much. It can be effective.

In addition, it has excellent elasticity, improves heat transfer efficiency, prevents rust and scale generated inside the pipe, and can withstand high temperature generated in a boiler while forming various diameters for ease of construction. have.

It is not desirable to interpret the words as used in the present specification and claims or to limit them to ordinary or private meanings, and the present invention is based on the principle that the concept of terms may be appropriately defined in order to best explain the inventor's invention. It should be interpreted as meanings and concepts consistent with the technical spirit of the invention.

Hereinafter, the configuration of the present invention in detail with reference to the accompanying drawings as follows.

1 is a working process diagram schematically showing a manufacturing method of a heating hose having a double structure of the present invention, Figure 2 is a reference diagram schematically showing a state using a heating hose having a double structure of the present invention.

First, the present invention forms a hot water pipe formed of a thermoplastic elastomer (TPV) made of rubber, which is a main raw material of the hot water pipe.

Then, the polybdenum layer having the activator Rosin is applied again to the entire inner circumferential surface of the pipe for hot water formed of the thermoplastic thermoplastic elastomer (TPV) of the rubber material, so that the cross-section of the structure is formed in a double structure.

At this time, the polybdenum layer applied to the entire inner circumferential surface of the pipe for hot water formed of a thermoplastic elastomer (TPV) of rubber material is a structure in which work can be performed through an extrusion molding machine.

On the other hand, the thickness of the pipe for hot water to be extruded through the extrusion molding machine is 3mm, it is preferable that the polybutene layer to be applied is configured to a thickness of 0.5mm.

Due to the manufacture of the heating hose having such a double structure, while having excellent elasticity properties, the workability and workability in the field can be used more efficiently.

On the other hand, the heat of hot water passing through the heating hose having a dual structure is rapidly transferred, the heating efficiency is greatly improved, and the deformation and wear of the material during long time use due to the rigidity and the invariability of the material while minimizing the scale generated inside the hose. There will be no at all.

Hereinafter, the present invention will be described in more detail with reference to the following Examples.

EXAMPLE

Corrosion test results

Metal specimens were used.

EXAMPLE

Scale Generation Test

-Cut and use plumbing pipe-

EXAMPLE

The change in temperature rise by connecting a heating hose having a dual structure used in the present invention with a boiler is shown in the table below.

TABLE 1

EXAMPLE

The change in temperature rise by connecting a commonly used Excel pipe hose to a boiler is shown in the table below.

TABLE 2

As described above, the heating hose having a dual structure made through the present invention was confirmed to rise to 110 ° C after 5 minutes.

On the other hand, in the case of the Excel pipe used in the prior art it was confirmed that the temperature rises to 93 ℃ over 8 minutes.

Therefore, when using a heating hose having a dual structure of the present invention there is an effect that can reduce the amount of oil and electricity required when heating the boiler.

In addition, in the case of using the heating hose having a double structure of the present invention, there is a feature that the situation in which corrosion and scale occurring in a metal pipe such as a copper pipe is generated does not occur at all.

As a result, the use of a heating hose having a dual structure of the present invention as a plumbing pipe of a boiler that is commonly used is to heat the ondol room and the panel part at high speed while heating at a high speed.
