Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pipe heater holder used to hold and hold a pipe heater for anti-freezing purposes.

[Conventional technology]

When a fluid, generally a liquid, is transferred through piping, it may be required to maintain the liquid piping at a constant temperature.

On the other hand, in cold regions, when the temperature of the pipes decreases due to a drop in the outside air temperature, and the fluid is transferred through the pipes, it is impossible to maintain the temperature of the pipes constant even if a heat insulating cover is attached to the pipes. Furthermore, if the fluid is tap water, the pipes may burst due to freezing. To prevent this freezing,
Conventionally, a heating element in the form of a wire or band is wound spirally or attached in a straight line between the outer periphery of the piping and the insulation cover, and this heating element heats the piping to prevent freezing. is being implemented. In this case, in order to attach the heating element to the piping, it is necessary to attach it while preventing loosening using conventional vinyl tape or the like. In such installation, winding or attachment may be difficult due to other obstacles, or workers may have to use a conductor such as wire to prevent loosening due to lack of electrical knowledge. In the double-wound portion and the loosening prevention portion using the wire, an electrical short may occur, causing abnormal heat generation in those portions and causing a fire. Heat insulating covers to block out cold outside temperatures are generally made of polystyrene foam material, which is resistant to low temperatures but weak to high temperatures and can cause a fire. There is.

On the other hand, the applicant (inventor) of the present invention has proposed a heat-generating heat-retaining heater (patent application filed in 1980-4) to solve the above-mentioned problems.
No. 4755), pipe insulation heater (patent application 1980-581)
No. 17), and pipe insulation heater (patent application 1980-15)
No. 4331) was invented and filed. Although each of these inventions has a different structure, each of these inventions has an elastic, electrically insulating and waterproof cylindrical body in which an opening is formed over the entire length of the cylindrical body. It has a structure in which a heating element is integrally arranged. To attach these heaters to piping, open the opening and attach it so that it hugs the piping.

These piping heat retention heaters are composed of a cylindrical body for attaching to the piping and a heating element for heating the piping, and are extremely effective in terms of installation and other aspects. There may also be cases where it is necessary to separately manufacture and attach a holder for attaching and holding the heating element to the piping.

[Problem that the invention seeks to solve]

``Double'', the conventional method for keeping pipes warm and preventing freezing of water pipes is a structure in which a linear or band-shaped metal resistance heating element is wound spirally around the pipe or attached in a straight line between the heat insulating cover and the pipe. Therefore, depending on the construction, there is a risk of a fire accident, and the work of attaching the heating element to the piping is complicated.

On the other hand, in the three types of pipe insulation heaters invented by the above-mentioned applicant (inventor) of the present invention, the cylindrical body, which is a means for attaching to the pipe, and the heating element are integrally constructed, so the heating element and To attach this to the piping, a holder, which is a means, must be manufactured separately, and if it becomes necessary to attach it to the piping, it will not be possible to use it.

The present invention overcomes the above-mentioned problems, prevents the occurrence of fire accidents in piping heat insulation covers, makes it simple and easy to attach the heating element to the piping, and furthermore provides a combination of the heating element and a holder for attaching it to the piping. The object of the present invention is to provide a pipe heater holder that can be used when the pipe heater holder is manufactured separately.

[Means for solving problems]

The means of the present invention for solving the above-mentioned problems is a pipe heater holder for holding a pipe heat-insulating heater and holding it on the pipe, characterized in that the pipe heater holder is made of a waterproof electrically insulating material that has a tassel property. It is a pipe heater holder having a cylindrical body formed with an opening extending over the entire length in the axial direction, and a heater fixing member having a C-shaped surface extending in the axial direction fixed to the inside of the cylinder. .

Furthermore, a plurality of rectangular notches are formed symmetrically in the opening, a plurality of triangular notches are formed in the opening, or the pipe heater holder is formed of a spiral string.

[Effect]

When attaching a heater to a pipe using the above-mentioned pipe heater holder, the heater can be attached easily and reliably, and electrical accidents such as leakage and short circuit can be prevented.
