Fig. 4 is a longitudinal sectional view of the state in which the device according to the present invention is assembled to a water supply line.

본 발명은 급수를 필요로 하는 소정의 장소로 급수를 하는 급수관(10)이 외기에 노출되어 동파가 되는 것을 방지하기 위해, 내부에 소정의 공간이 마련되는 반원형의 제 1,2순환부(20)(20a)를 구비하여, 외기에 노출된 상기 급수관(10)의 외측면을 감싸도록 조립한다.According to the present invention, in order to prevent the water supply pipe 10 supplying water to a predetermined place requiring water supply from being exposed to the outside air and freezing, the semicircular first and second circulation portions 20 having a predetermined space therein are provided. ) Is provided to surround the outer surface of the water supply pipe 10 exposed to the outside air.

따라서, 상기 제 1,2순환부(20)(20a)의 내측면에는 급수관(10)의 외측을 감싸도록 결합부(21)가 반원형으로 형성되며, 외측면 일측에는 제 1,2순환부(20)(20a)를 서로 체결하여 주기 위한 체결구(22)가 구비된다.Therefore, the coupling part 21 is formed in a semicircular shape so as to surround the outside of the water supply pipe 10 on the inner surface of the first and second circulation parts 20 and 20a, and the first and second circulation parts 1 and 2 on the outer side surface. 20 and 20a are provided with fasteners 22 for fastening each other.

또한, 상기 제 1순환부(20)의 후단에는 급수관(10)과 연통 연결되는 유입관(31)이 구비되며, 제 1순환부(20)의 내측 중도에는 선단까지 길게 인출되어 외부로 관통 형성되는 분사관(30)이 구비되어 상기 유입관(31)과 연통 연결된다.In addition, an inlet pipe 31 connected to the water supply pipe 10 is provided at the rear end of the first circulation part 20, and the inner half of the first circulation part 20 is extended to the front end so as to penetrate to the outside. Is provided with a spray pipe 30 is connected to communicate with the inlet pipe (31).

그리고, 제 1순환부(20)와 제 2순환부(20a)를 서로 연통시켜 주기 위한 연통관(23)이 구비되며, 제 2순환부(20a)의 후단에서 연통 연결되는 급수관(40)이 구비된다.In addition, a communication tube 23 for communicating the first circulation portion 20 and the second circulation portion 20a with each other is provided, and a water supply pipe 40 connected with the rear end of the second circulation portion 20a is provided. do.

아울러, 상기 유입관(31)의 중도부에는 고압펌프(50)가 설치되어 급수관(10)의 물을 제 1순환부(20)로 용이하게 유입되도록 하는 것은 물론, 배출관(40)을 통해 제 2순환부(20a)의 물이 용이하게 배출되도록 한다. 순환부(20)(20a)의 내측에는 온수가열기(60)를 설치하여 소정의 온도로 가열한다.In addition, the high-pressure pump 50 is installed in the middle portion of the inlet pipe 31 so that the water in the water supply pipe 10 can easily be introduced into the first circulation portion 20, as well as through the discharge pipe 40. The water of the two circulation portion 20a is easily discharged. The hot water heater 60 is installed inside the circulator 20 and 20a and heated to a predetermined temperature.

따라서, 동파를 방지하고자 하는 급수관(10)의 외측에 상기와 같이 구성되는 본 발명의 제 1순환부(20)와 제 2순환부(20)의 결합부(21)를 급수관(10) 외측에 밀착시킨 후, 체결구(22)에 의해 견고히 체결한다. 그리고, 유입관(31)과 연통관(23) 및 배출관(40)을 각각 조립한다.Therefore, the coupling portion 21 of the first circulation portion 20 and the second circulation portion 20 of the present invention configured as described above on the outside of the water supply pipe 10 to prevent freeze on the outside of the water supply pipe 10. After making close contact, it fastens firmly by the fastener 22. As shown in FIG. And the inflow pipe 31, the communication pipe 23, and the discharge pipe 40 are assembled, respectively.

이렇게 본 발명의 장치가 조립된 급수관(10)의 주변 온도가 소정 온도 이하로 하강하게 되면, 고압펌프(50)가 작동하고 급수관(10)에 흐르는 물의 일부가 유입관(31)을 통해 제 1순환부(20)의 내부로 유입되어 분사관(30)을 통해 고압으로 분사된다.When the ambient temperature of the water supply pipe 10 to which the apparatus of the present invention is assembled is lowered below a predetermined temperature, the high pressure pump 50 operates and a part of the water flowing in the water supply pipe 10 passes through the first inlet pipe 31. Is introduced into the circulation portion 20 is injected at a high pressure through the injection pipe (30).

따라서, 제 1순환부(20)의 깊숙한 곳까지 연장되어 있는 분사관(30)에 의해 제 1순환부(20)의 선단에서 고압으로 분출이 되며, 분출된 물은 제 1순환부(20)이 충진된 후 다시 연통관(23)을 통해 제 2순환부(20a)로 유입되고, 제 2순환부(20a)의 물은 배출관(40)을 통해 급수관(10)으로 순환된다.Therefore, the injection pipe 30 extending to the depth of the first circulation part 20 is ejected at a high pressure from the tip of the first circulation part 20, the ejected water is the first circulation part 20 After the filling is introduced again into the second circulation portion 20a through the communication tube 23, the water in the second circulation portion 20a is circulated to the water supply pipe 10 through the discharge pipe 40.

이렇게 고압의 물이 제 1순환부(20)에서 분출된 후 다시 제 2순환부(20a)로 유입되어 급수관(10)으로 배출됨에 따라 순환부(20)(20a) 내의 물이 항상 유동적이게 됨으로써, 순환부(20)(20a) 내부의 기온이 급감하지 않게 되므로, 급수관(10) 내부의 물이 동결되지 않게 된다.As the high pressure water is ejected from the first circulation part 20 and then flows back into the second circulation part 20a and is discharged into the water supply pipe 10, the water in the circulation parts 20 and 20a is always fluid. Since the temperature inside the circulation section 20 (20a) does not decrease rapidly, the water inside the water supply pipe 10 does not freeze.

또한, 순환부(20)(20a)로 유입되는 물을 온수가열기(60)에 의해 소정 온도 이상으로 가열함으로써 급수관(10) 내부의 물이 소정 온도 이상을 유지하여 동파방지의 효과를 증대시킬 수 있다.In addition, by heating the water flowing into the circulation section 20 (20a) to a predetermined temperature or more by the hot water heater 60, the water in the water supply pipe 10 to maintain a predetermined temperature or more to increase the effect of freezing prevention. Can be.

본 발명은 상기와 같이 급수관의 외측에 항상 유동적으로 물이 흐르도록 함으로써, 급수관이 동결되는 것을 막아 급수의 중단 및 파손을 방지하여 급수관의 수명을 연장하며, 교체작업을 위한 비용 등을 절감할 수 있는 매우 경제적인 발명이다.The present invention is to ensure that the water always flows to the outside of the water supply pipe as described above, to prevent the water supply pipe from freezing to prevent the interruption and breakage of the water supply to extend the life of the water supply pipe, and to reduce the cost for replacement work That is a very economical invention.
