Description

Circulating pump system for preventing winter damage of water pipe}

The present invention relates to a circulating pump device for preventing the freezing of water pipes, and more particularly, in order to smoothly induce the flow of tap water in the remaining pipes using a movable wing member mounted with a heating wire during winter, and thus, the water supply pipe is damaged due to freezing. It relates to a circulating pump device for preventing water pipe freeze.

In general, water supplies supplying water for daily living are intake facilities to collect the necessary water, water supply facilities to the demand sites, water purification facilities to improve and purify the water quality, and drainage facilities to be transported to the city with the required water pressure and quantity and drained to the vicinity of the consumers' residence. It consists of a water supply system that supplies pipes to the faucet in the user's site or building.

All these devices are organically connected by pipes of different diameters depending on the water supply and the water source.

In general, water pipes supplied to homes and restaurants are rarely damaged by the warm temperature of the room.

However, since outdoor water pipes installed to use water outdoors, such as a parking lot and a yard, are exposed to the outside, the water stored in the water pipes freezes and expands due to the cold weather in winter.

Therefore, in order to prevent the freezing caused by the cold weather in winter, the outer circumferential surface of the water pipe exposed to the outside was thickly wrapped with a styrofoam insulating material or a warming cloth, and prepared to prevent the water stored in the water pipe from freezing.

However, in order to insulate outdoor water pipes in this way, if the insulation is not done perfectly when wrapped with a heat insulating material or a cloth for insulation, the heat insulating material and cloth do not adhere completely to the water pipes, and thus form a space. Lowering the water generated in the water pipe freezes the problem of freezing the water pipes, as well as the material surrounding the water pipes, especially snow due to the likelihood that the water pipes freeze easily freezes often occurred.

In addition, in order to prevent the freezing of the water pipe installed in the outdoor as described above, when the winter comes back every year, the new heat insulating material is insulated according to the above-described method. In addition, after installation, there was a defect that was not aesthetically clean, and even if the temperature dropped a lot, it would be useless.

Therefore, the water pipe freeze protection device proposed as a method for preventing the freezing of outdoor water pipes in winter is used to prevent the freezing of water pipes in winter. It is a technology that prevents freezing by keeping the state.

However, the above configuration requires a separate construction by connecting a piping configuration for installing a separate compression pump to the water pipe in order to drain the water stored in the outdoor water pipe, and requires an increase in installation space and construction cost, and also requires a lot of parts and materials. There is an economic burden, so not only the problem that consumers prefer, but also the compression pump should be operated every time tap water is used, so there was a short lifespan.

In addition, as a simple method for preventing freezing, the configuration generates heat energy in the water pipe so that the outdoor water pipe does not freeze in winter, and is equipped with a temperature sensor in the water pipe to prevent freezing of the water pipe, and then detects the temperature in the water pipe all winter. It was made.

In other words, when the temperature in the water pipe is below zero, thermal energy is applied to the water pipe to prevent freezing of the water pipe. However, since the electric wiring work for connecting the electric wires to the external water pipe is complicated, and the electric power is supplied to detect the temperature in the water pipe at all times in winter, the device is not only economically lost due to electricity consumption but also fires due to electric leakage. There was a risk of becoming.

In addition, in order to prevent the freezing of the water pipes exposed to the outside in the winter as described above, only the water pipes were kept warm, but the water pipes connected to the inside were not kept warm.
