Description

System for preventing winter sowing of pipe arrangement

The present invention relates to a freeze protection system installed in a boiler's water supply and drainage line, and more specifically, using a hot water heat of a boiler, using a hot water heat from a boiler without using an external power source or heat source. It relates to a freeze protection piping system for preventing freezing of the water supply line of the water supply line, in particular for the hot water supply pipe or drainage pipe or heating water supply pipe.

Most homes operate boilers for winter heating. Most boilers have hot water pipes for use in bathrooms, etc. in hot water heaters for heating. Unlike the hot water circulating water, the hot water pipe is connected to the water pipe and when the hot water is not used, the water circulation stops. In homes, boilers are installed in boiler rooms, but heat radiators are not installed in boiler rooms. If the ambient temperature falls below freezing during the cold winter season, the direct water supply pipe and hot water drain pipe connected to the hot water pipe will freeze and burst. In particular, since the water flows in the hot water pipe during the time of using hot water, such as in the evening, the direct inflow pipe is less likely to rupture, but at 2 o'clock, when the temperature is lowest, the ambient temperature is low. It will freeze until it bursts.

In order to prevent freezing of the hot water pipe, the valve of the hot water pipe should be opened slightly so that the water flow is always maintained in the hot water pipe so that the water can always circulate in the hot water pipe. However, this method presents a problem of unnecessary waste of water. Recently, in order to prevent freezing of the hot water pipe, a heating wire is wound around the hot water pipe, and the freezing of the pipe is prevented by using heat transfer by external power. The conventional freeze protection method not only causes unnecessary power loss but also a hot water pipe is heated, which may cause a fire. In particular, the method of heating with a heating wire causes a problem in that the pipe melts or deteriorates due to overheating when the pipe is made of synthetic resin, thereby shortening the life of the pipe.

The present invention is to solve the problems appearing in the freeze protection of the direct inflow pipe supplied to the conventional boiler.

It is an object of the present invention to provide a boiler piping system adapted to prevent freezing of the direct inlet pipe of a boiler by its own heat.

The object of the present invention described above is achieved by the boiler piping system of the present invention configured to connect a flexible hose to the hot water circulation pipe for heating the boiler and to circulate the hot water with the hose to heat the hot water direct inlet pipe.

1 is a piping diagram showing a freeze protection system of the present invention.

The present invention is achieved by connecting a flexible hose different from a heating pipe to a hot water circulation pipe for heating a boiler, in particular a hot water supply pipe, and winding the hose around a direct water supply pipe for hot water connected to a water pipe. do.

In the present invention, the flexible hose may be directly connected to the hot water supply pipe discharged from the boiler or may be connected to the hot water distribution pipe. And the end of the flexible hose may be connected to the heating water return pipe, or if the tip of the flexible hose is connected to the hot water supply pipe of the boiler may be connected to the distribution pipe. If the boiler is installed in a location that is not severely affected by the outside temperature, and freezing is prevented by slight heating, the end of the flexible hose may be closed so that it is heated only by hot water convection inside the flexible hose.

If the flexible hose is directly connected to the hot water supply pipe for heating, it is preferable to use a T-type connection pipe. When connecting the flexible hose to the hot water distribution pipe, a branch pipe is formed in the hot water distribution pipe to connect the hot water distribution pipe to the hot water distribution pipe. It is good to have a connection.

Flexible hoses are preferred to be wound around the water supply line, but where it is difficult to connect to the water supply line, they may be installed parallel to the hot water line.

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

The pipe freeze protection system of the present invention includes a hot water circulation pipe for heating, such as a diesel boiler or a gas boiler, and a hot water circulation pipe used in a kitchen or a bathtub. The boiler was to be heated by gas or diesel burner or heater not shown. The boiler 10 has a hot water supply pipe 14 connected to the heating pipe 12 and a return pipe 16 through which hot water circulated flows into the boiler. In the boiler, a hot water pipe 18 for generating hot water for a bath or kitchen is installed. Connected.

The hot water pipe 18 and the hot water supply pipe 14 connected to the boiler are connected to each other by a T-shaped connecting pipe 24 having a branch pipe 26, and the hot water supply pipe 14 is heated through a distribution pipe 30. Connected to (12). A flexible hose 28 is connected to the branch pipe 26 of the connecting pipe 24, and the flexible hose 28 is wound around the outer circumference of the water supply pipe 20, and an outer end thereof is a connection formed in the distribution pipe 30. Connected to the tube (24).

In the pipe freeze protection piping system of the present invention, when the boiler is running, some of the hot water supplied to the heating pipe 12 flows through the flexible hose and heats the water supply pipe 20 so that water is stagnated in the hot water pipe 18. Even when the direct water supply pipe 20 is heated, a phenomenon in which the direct water supply pipe 20 freezes in winter is not observed.

According to the present invention, since the direct water supply pipe 20 is not heated by an external heat source, but heats the direct water supply pipe 20 by the heat of hot water from the boiler, there is no waste of energy, and the direct water supply pipe 20 uses heat transfer. There is an effect that can prevent the risk of fire due to overheating when heating.
