Description

[0002] Plumbing Anti-Freeze System [

The present invention relates to a system for preventing freezing of a water pipe used in water supply, sewage, and fire fighting, and more particularly, to a system for preventing water from being exposed to the outside of a winter water pipe, such as water supply, sewage, By installing a by-pass water pipe and heating or circulating the water of the bypass water pipe, the energy for installing the hot wire of the entire large water pipe and the installation cost can be saved and the risk of fire by the heat- The present invention aims at constructing a water pipe to prevent the freezing of the water pipe by circulation of the water rather than the heat generation, and it is easy to find the position of the short circuit when the heat pipe is short-circuited.

Generally, in order to prevent freezing of the water pipe exposed to the outside air, it is necessary to wind the hot wire which is operated when the outside air temperature falls below the freezing point on the outer surface of each water pipe, To prevent the water pipe from freezing by winding the reinforcing tape so that the insulating material does not fall off.

The frost protection system of the water pipe surrounds a hot wire operated by electricity on the outer surface of the exposed water pipe and supplies electric power to the hot wire operated by electricity when the outside temperature falls below the freezing point, The water inside the water pipe is prevented from falling below the freezing point, preventing the water pipe from freezing.

However, in the conventional system for preventing the freezing of the water in the water pipe as described above, a lot of electric charges are generated to generate heat in the hot line, and the risk of fire due to the overcurrent between the hot line connecting part and the insulating material of the water pipe And it is difficult to confirm the short-circuit position at the time of short-circuiting of the heating wire, so that it is necessary to remove the insulating material of the whole water pipe and repair and find a short-circuit point because a reinforcing material such as a heat insulating material and a reinforcing tape surrounds the water pipe.

As described above, according to the present invention, in the conventional system for preventing freezing of water in the water pipe, a large amount of electricity charges are generated to generate heat in the hot wire, and a fire caused by the overcurrent between the hot wire connecting portion and the insulating material of the water pipe And it is difficult to confirm the short-circuit position at the time of short-circuit of the hot wire because the water pipe and the reinforcement material such as tape are wrapped in the water pipe so that the insulation of the whole water pipe is removed, It is.

That is, in order to prevent water pipes such as water supply, sewage, and firefighting from being exposed to the outside in the winter and to be frozen, a bypass water pipe is provided in the water pipe, and the water of the bypass water pipe is heated or circulated It is possible to save the energy and installation cost of installing the hot wire of the whole large water pipe and to reduce the risk of fire caused by the heat insulating tape touching the hot wire and it is easy to find the position of the short circuit when the hot wire is short, The water pipe is configured to prevent the water pipe from being frozen by circulation of the water pipe.

Therefore, in order to prevent water pipes such as water supply, sewage and fire fighting from being exposed to the outside in winter, a bypass water pipe is installed in the water pipe, and the water of the bypass water pipe is heated or circulated It is possible to save the energy and installation cost of installing the hot wire of the whole large water pipe and to reduce the risk of fire caused by the heat insulating tape touching the hot wire and it is easy to find the position of the short circuit when the hot wire is short, The flow of water in the water pipe is prevented.

2 is a block diagram of a bypass thermal < RTI ID = 0.0 >
FIG. 3 is a view illustrating a system for preventing a frost wave using a hot wire of a conventional water pipe

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In order to prevent water pipes such as water supply, sewage, and firefighting from being exposed to outside in winter, a bypass water pipe is provided in the water pipe, and the water in the bypass water pipe is heated or circulated, It is possible to save the energy and installation cost of installing the hot wire 210 of the entire large water pipe 100 and to reduce the risk of fire caused by the reinforcing tape 230 of the heat insulating material 220 in contact with the hot wire, And it constitutes a water pipe to prevent freezing of the water pipe by the circulation of the water, not the heat.

That is, as shown in FIG. 1, the present invention is characterized in that a flow rate sensor 110 is installed in a water supply pipe 100 such as water supply, sewage, fire, etc., and a bypass branch 120 is installed , And a bypass water pipe having a size smaller than that of the water pipe is connected between the two bypasses.

The bypass circulation pump 130 shown in Fig. 1 operated by the flow rate sensor may be installed in the bypass water pipe, or the bypass heat pipe 140 may be wound around the bypass water pipe shown in Fig. 2 And a bypass heat insulating material 150 are attached so that no water is generated in the water pipe.

Hereinafter, the operation of the present invention will be described.

As described above, in order to prevent water pipes such as water supply, sewage, fire, and the like from being exposed to the outside in the winter and being frozen, a bypass water pipe is provided in the water pipe, and the water of the bypass water pipe is heated or circulated It is possible to save the energy and installation cost of installing the hot wire of the whole large water pipe and to reduce the risk of fire caused by the heat insulating tape touching the hot wire and it is easy to find the position of the short circuit when the hot wire is short, When the external temperature in contact with the water pipe falls below the freezing point and the flow of the water pipe in the flow sensor of the water pipe is not detected, the bypass circulation pump is operated , The water of one bypass branch tube is sucked and the water of the other bypass branch pipe is sprayed, A circulation flow is generated.

In addition, even if a by-pass heat pipe is used for the bypass water pipe instead of the bypass circulation pump, the flow of the water in the water pipe occurs due to the change in density due to the temperature difference in the water.

At this time, the circulation flow of the water pipe prevents the freezing of water in the water pipe due to the effect of not freezing the flowing water such as partially opening the faucet to prevent the water pipe from being frozen, and bypassing the bypass water pipe smaller than the water pipe Since the circulation pump is installed, the cost of electricity and installation is saved, and only the bypass circulation pump is checked, so that the cost of removing the entire heat insulation due to a short circuit of the heat wire does not occur.
