The present invention relates to a device for preventing the freezing of water pipes, and more particularly, to a freezing prevention device for preventing the freezing of the pipe by discharging a small amount of water in the pipe in accordance with the change in the outside temperature.

In general, when water freezes in winter, the volume increases, and when water inside the water pipe is frozen due to the low temperature of the winter, cracks in the water pipe due to the volume increase. Therefore, various apparatuses and methods have been used to prevent this from before.

Since most of the water pipes are buried underground, the buried parts of the water pipes hardly fall below the freezing point of water even in winter. Therefore, most water pipe freeze protection devices are intended for water pipes exposed on the ground.

The simplest way to prevent freezing of water pipes is to wrap the exposed parts of the ground with insulation such as styrofoam. This method is widely used because it does not require special equipment and is advantageous in terms of cost, but it is not easy to be damaged due to weather or children's mischief because it is less durable due to the material properties of the insulation. There is no shortcoming because the temperature is very low and eventually freezes.

Therefore, not only the purpose of preventing freezing by using a heating device such as a heater, but also a device for dissolving frozen water is used. That is, a device has been proposed to control the temperature of the water pipe exposed to the ground by using a heater with a built-in heating wire so as not to fall below the freezing point. Covered with a built-in case to prevent freezing is used. This type of freeze protection device is limited in its application because it is manufactured in a form suitable for a specific portion of the water pipe. That is, the freeze protection device for a water meter cannot be used for other water pipes. In addition, it can be applied only to the part exposed to the ground surface, and to apply to the buried part, not only can the device be installed after the excavation, but also very disadvantages in terms of maintenance and management.

In the conventional freeze protection apparatus shown in FIG. 1, a pipe 1 through which fluid flows inside and a pipe 1 fixed to an outer surface of the pipe 1 through a fixing member 2 and supplied with power from the outside The heating wire 3 for heating the power supply to the heating wire 3 in accordance with an atmospheric temperature (for example, 3 ° C. or less) connected to the heating wire 3 and detected by a temperature sensor (not shown). The control part 4 which prevents (1) from freezing is provided, and the power plug 5 which supplies electric power to the control part 4 from the exterior is provided.

Conventional pipe freeze protection device, the control unit 4 controls to heat the pipe 1 by always supplying power to the heating line (3) when the temperature value detected by a temperature sensor (not shown) is below a certain temperature. It is installed. In fact, the atmospheric temperature is a temperature condition that can freeze the pipe (1), but because the heating of the pipe (1) even under the condition that the pipe flowing the fluid has a problem of having to bear a large maintenance cost burden due to enormous power consumption. In addition, since the conventional heating type freeze blocker must operate artificially, it has a fatal drawback in that freezing occurs even though there is a device when the temperature suddenly drops at night from the temperature of the image during the day.

Moreover, the inventors of the present invention described in Utility Model Registration No. 20-0309420 registered as a designation "freezing prevention device" dated March 21, 2003 by the inventor of the present invention, there was a complicated structure.

The present invention is to solve the above-mentioned conventional problems, an object of the present invention is to discharge a small amount of water in the pipe when the outside temperature decreases by the opening and closing operation of the opening and closing means interlocked in accordance with the expansion and contraction of the corrugated pipe of the pipe It is to provide a freeze protection device for preventing freeze.

Another object of the present invention is to provide a freeze protection device that is simple in structure and does not require maintenance costs, and is easy to install in home and industrial piping.

The present invention for realizing such an object is provided with an inlet and an outlet on the ground water pipe, the housing is provided with an exhaust port in the lower, and connected to the temperature sensing unit installed inside the housing and the outside of the housing And a corrugated pipe that contracts and expands in a vertical direction according to the external temperature conversion, and is installed on the lower surface of the corrugated pipe and moves up and down according to the contraction and expansion of the corrugated pipe to open and close the exhaust port, and is installed on the outer circumferential surface of the open / close means.

On the other hand, the central lower surface of the corrugated pipe 130 described above forms a protruding stepped portion 132, and the stepped groove 141 corresponding to the stepped portion 132 is formed on the upper end surface of the opening and closing means 140 to form a coupling force. In addition, the exhaust port 114 is provided with an exhaust pipe 160 protruding from the lower surface of the housing 110, and an inner side surface of the exhaust pipe 160 with a packing of rubber material corresponding to the lower shape of the opening and closing means 140. 162 is further installed.

The opening and closing means 140 of the first embodiment includes a first valve 142 having a head portion 142a for supporting the corrugated pipe 130 and the auxiliary spring 134 from the bottom and a female screw formed on the inner side thereof. The male screw that is fastened to the female screw of the first valve 142 is protruded, and the lower portion has a form of a light-receiving narrow and has a second valve 144 having a length adjusting groove 145 formed thereon.

In the second valve 144, the lower length of the upper and lower sheaths is preferably formed to have a length that does not deviate from the exhaust port 114, and the material may be a material that is not easily corroded to water.

In addition, the exhaust pipe 160 is provided with a water discharge amount control valve 170 that can adjust the amount of water discharged, the water discharge amount control valve 170 according to the rotation of the grip portion 172 and the grip portion 172 is rotated screw The blocking plate 174, which is integrally connected to the gripping portion 172, opens and closes the inside of the exhaust pipe 160 to adjust the amount of discharged water.

And the opening and closing means 200 of the second embodiment shown in FIG. 4 includes a first valve 210 having a head 212 for supporting the corrugated pipe 130 at a lower portion thereof and a female screw formed at an inner side thereof. The male screw which is fastened to the female screw of the first valve 210 is protruded, and is formed as a second valve 220 formed with a communication hole 222 having a "-" shape in the lower inner side.

Furthermore, the exhaust pipe 114 has an exhaust pipe 230 having a discharge hole 232 for discharging water in the housing 110 to the outside when facing the communication hole 222 as the opening and closing means 200 moves up and down. This is installed. Preferably, the exhaust pipe 230 penetrates through the exhaust port 114 of the housing 110 so that one end of the outlet hole 232 is formed inside the housing 110, and the other end protrudes out of the housing 110. .

In addition, a spring 240 is further installed between the second valve 220 and the exhaust pipe 230 of the opening and closing means 200.

The operation of the freeze protection device having such a structure is performed as follows.

First, according to the first embodiment of FIG. 3, before the housing 110 is installed on the water pipe, the user may arbitrarily change the opening / closing means 140 according to the location and temperature deviation of the freeze protection device 100. By adjusting the overall length, the degree of opening and closing is set to some extent. In other words, depending on the region or country, for example, the pressure in the piping near the pressurized pumping station and the highland is different so that the pressure of the water coming out through the final valve in the piping is different. It needs to be adjusted.

Accordingly, by rotating the length adjusting groove 145 in one direction with the separate equipment such as a driver through the exhaust pipe 160, the length of the second valve 144 that is fastened to the female screw of the first valve 142 is adjusted. Within 110, the overall length of the opening and closing means 140 is adjusted.

The water supply pipe is connected to the inlet 111 and the outlet 112 of the housing 110 is set as follows.

For example, when the temperature drops below the set temperature, for example, when the temperature drops below about 1 ° C., the cooling fin 124 inside the case 122 communicating with the outside senses the outside temperature and the reduced temperature is corrugated. Direct to material within 130.

Therefore, the material in the corrugated pipe 130 is contracted as the temperature decreases, thereby shrinking the entire wrinkle tube 130. At this time, the compression action of the corrugated pipe 130 is released and at the same time, the opening and closing means 140 is moved upward along the corrugated pipe 130 by the spring 150 which is normally compressed.

Accordingly, the exhaust pipe 160 is opened by the rising of the second valve 144 of the opening and closing means 140, which is inserted into the packing 162, and the water in the housing 110 opens the open exhaust pipe 160. Through the discharge.

At this time, the adjustment of the water discharge amount control valve 170 by the user's selection can also adjust the amount of exhaust water. That is, as the user rotates the gripping portion 172 in one direction, the blocking plate 174 adjusts the opening degree in the exhaust pipe 160.

As described above, the water is partially discharged through the housing 110 before the water charged into the water pipe is frozen, thereby preventing freezing of the water in advance.

When the air temperature rises again during the day, the corrugated pipe 130 is expanded, and the opening and closing means 140 blocks the inlet of the exhaust pipe 160 while compressing the spring 150 according to the expansion of the corrugated pipe 130.

In addition, according to the second embodiment, the same as the operation of the first embodiment, but as opening and closing the outlet hole 232 of the exhaust pipe 230 in accordance with the lifting and lowering of the opening and closing means 200, the opening and closing means when the temperature rises ( Due to the lowering action of the 200, the communication hole 222 of the second valve 220 is lower than the water discharge hole 232 so that water is not discharged.

On the other hand, when the temperature decreases, the opening / closing means 200 is lifted so that the communication hole 222 of the second valve 220 communicates with the water outlet hole 232 of the exhaust pipe 160 in the housing 110. Water is discharged through these discharge hole 232 and the communication hole 222.

As described above, the freeze protection device of the present invention has the effect of preventing the freezing of the pipe by discharging a small amount of water inside the pipe when the outside temperature decreases by the opening and closing operation of the opening and closing means interlocked with the shrinkage and expansion of the corrugated pipe. have.
