본 고안은 물의 회로에 삽입하는 역지변에 관한 것으로 급탕기의 물회로에 이용할 수 있을뿐 아니라 동결방지를 위한 도피변을 취부할 수 있는 회로에 채용하는 경우에 특히 유효한 것이다.The present invention relates to a reverse displacement to be inserted into a circuit of water, and is particularly effective when used in a circuit that can be used not only in the water circuit of a hot water heater, but also in which the escape valve for freezing prevention can be mounted.

급수회로, 급탕회로에는 수도회로측에의 역류를 방지하는 의미에서 역지변이 조립되어 이런류의 역지변으로서 제4도와 같은 형식의 것을 채용하여 왔다.In the water supply circuit and the hot water supply circuit, a reverse displacement is assembled in the sense of preventing reverse flow to the water circuit side, and the reverse displacement of this kind has been adopted as the type shown in FIG.

그러나 이것은 하류측에 변체(11)를 형성하여 그 상류측에 변좌(12)를 형성한 것으로서 이 변좌(12)의 상류측이 부압상태가 되면 변체(11)는 그때의 압력차에 의하여 변좌(12)에 눌리워 변좌(12)의 상류측(예컨대 수도배관)에의 역류가 저지된다.However, this is a toilet 11 formed on the downstream side and the toilet seat 12 is formed on the upstream side, when the upstream side of the toilet seat 12 is in a negative pressure state, the toilet seat 11 is the toilet seat ( 12), the backflow to the upstream side (for example, the water pipe) of the toilet seat 12 is prevented.

그런데 이 종래의 것은 변좌(12)의 상류측과 하류측과의 사이에 압력차가 발생하지 않는다.By the way, this conventional thing does not generate a pressure difference between the upstream side and the downstream side of the toilet seat 12. As shown in FIG.

즉 자연상태에서 변체(11)가 변좌(12)에 맞닿은 위치에 있고 역류방향의 유로는 차단되고 있다.That is, in the natural state, the deformed body 11 is in contact with the toilet seat 12 and the flow path in the counterflow direction is blocked.

따라서 급탕기의 물 계통의 배관등에 이 역지변이 조립된 것에서는 동결방지를 위하여 이 배관내에 물이 빠졌을때 변체(11)와 변좌(12)와의 접촉부분에 물이 부착 잔존하게 되고 동결온도로 분위기 온도가 상하하면 상기의 부착 잔존된 물이 동결하여 변체(11)와 변좌(12)가 얼어붙어 재사용시에는 상기한 얼은물이 녹을때까지 역지변이 작동하지 않아 사용 불능이 된다.Therefore, in the case where this reverse valve is assembled in the water system pipe of the water heater, when water is drained in this pipe to prevent freezing, water adheres to the contact portion between the deformed body 11 and the toilet seat 12 and the atmosphere is kept at a freezing temperature. When the temperature rises and lowers, the remaining adhesive water is frozen, and the deformed body 11 and the toilet seat 12 are frozen, and upon reuse, reverse displacement does not work until the frozen water is dissolved, thereby making it impossible to use.

그 이유는 자연상태에 있어서 변체(11)가 폐변상태에 있기 때문이다. 본 고안은 동결조건하에 물을 뽑았을때에 역지변이 폐변상태 그대로 얼어 붙는 것을 방지하기 위하여 자유로운 상태에 있어서 역지변의 변체가 그 변좌에 닿지 않도록 함을 과제로 한 것으로 상기 과제를 해결하기 위한 본고안은 변좌(12)에 대향한 변체(11)를 그 자유로운 상태에 있어서 상기 변좌(12)에 약간의 간극을 두고 위치시켜 그 간극유지를 위한 탄지수단을 구비한 것으로 즉, 변체(11)는 변좌(12)에 대하여 약간 개변한 상태로 유지되어 있으나 이 개변 간극유지를 위한 탄지수단은 약하므로서 변좌의 상류측이 부하상태가 되었을때에는 이 압력차에 의하여 변체(11)는 탄지수단에 저항하여 개변하고 역지기능을 발휘한다.This is because the variant 11 is in a closed state in a natural state. The present invention aims to solve the above problem by preventing the reverse displacement from reaching the toilet seat in a free state in order to prevent the reverse displacement from freezing as it is when the water is drawn under freezing conditions. The subject of the present invention is that the toilet 11 facing the toilet seat 12 is positioned with a slight gap in the toilet seat 12 in its free state, and is provided with holding means for maintaining the gap, that is, the toilet 11 Is maintained slightly modified with respect to the toilet seat 12, but the holding means for maintaining the opening gap is weak, and when the upstream side of the toilet seat is in a load state, the valve 11 resists the finger holding means by this pressure difference. Alter and exert a reverse function.

또 역지변이 삽입될 회로가 물을 뺀상태에 있어서는 변좌(12)와 변체(11)사이에는 약간의 간극이 있으므로 부착 잔존된 물이 변좌(12)와 변체(11)와의 사이를폐쇄하지 않고 동결시에 있어서도 변체(11)또는 변좌(12)각각에 부착한 물이 각각 얼게 된다.In addition, when the circuit into which the reverse displacement is inserted is drained, there is a slight gap between the toilet seat 12 and the toilet 11, so that the remaining water attached does not close between the toilet seat 12 and the toilet 11. Even in the case of freezing, the water attached to each of the deformed body 11 or the toilet seat 12 is frozen.

이상과 같이 구성된 본 고안은 변체(11)와 변좌(12)에 부착한 물이 일체적으로 동결하여 폐변상태로 고착되는 불합리점을 방지할 수 있어 재사용시 빨리 사용할 수 있고 동결의 용해를 기다릴 필요가 없다.The present invention constituted as described above can prevent the irrational point that the water attached to the deformed body 11 and the toilet seat 12 are fixed in a closed state by being frozen in one body and can be used quickly when reused, and need to wait for the dissolution of the freeze. There is no.

제1도에 표시한 제1실시예는 변체(11)의 자중에 의하여 탄지력으로 변체(11)가 그 자유로운 상태에 있어서 변좌(12)와 일정간극을 갖도록 한 것으로 본체(1)내의 유로(13)는 입구(14)에서 출구(15)를 향하여 수평방향에 설정한다.In the first embodiment shown in FIG. 1, the body 11 has a constant gap with the toilet seat 12 in a free state due to the force of the body 11 due to its own force. 13 is set in the horizontal direction from the inlet 14 toward the outlet 15.

변좌(12)는 유로(13)의 축선에 대하여 직각 방향에서 약간 경사지게 형성되며, 변좌(12)는 하류측을 향하여 기울게 하측을 향한다.The toilet seat 12 is formed to be slightly inclined in the direction perpendicular to the axis of the flow path 13, the toilet seat 12 is inclined toward the downstream side toward the lower side.

변체(11)는 지지점(16)을 중심으로 하여 요동하는 형식으로 이 지지점(16)이 변좌(12)의 하류측에서 또 이변좌의 상단근방에 위치한다.The deformable body 11 swings around the support point 16, and this support point 16 is located in the downstream of the toilet seat 12, and near the upper end of the toilet seat.

여기에서 변체(11)가 자유로운 상태에서는 제1도의 (B)상태로서 변좌(12)와의 사이에 일정간격이 있으며, 통상적인 사용상태에서는 변체(11)는 흐름에 따라서 제1도의(C)상태로 전부 열려지고 상류측이 저압이 된 상태(역류조건)에서는 변체(11)는 변좌(12)에 대접(對接)되어 제1도의(A)와 같이 폐변한다.Here, in the state where the variant 11 is free, there is a certain interval between the toilet seat 12 as the (B) state of FIG. 1, and in the normal use state, the variant 11 is the state of FIG. In the state where the furnace is completely opened and the upstream side is low pressure (reverse flow condition), the deformed body 11 is welded to the toilet seat 12 and closed as shown in FIG.

이 역지변(10)을 제2도와 같이 급탕기의 물회로(2)에 삽입하여 물빼기(21)을 같이 이 물회로에 삽입한 구성으로 하면 물빼기(21)을 개변시켜서 물을 뺀 상태에서는 변체(11)가 제1도의(B)상태에 있게 되고 변체(11)와 변좌(12)와의 사이에 간극이 있게 되어 상술한 효과를 얻게 된다.When the reverse side 10 is inserted into the water circuit 2 of the water heater as shown in FIG. 2 and the water drain 21 is inserted into the water circuit together, the water drain 21 is changed to drain the water. The deformed body 11 is in the state (B) of FIG. 1 and there is a gap between the deformed body 11 and the toilet seat 12 to obtain the above-described effect.

다음에 제3도에 표시한 실시예의 것은 스프링(17)에 의하여 약간 개변 탄지력을 변체(11)에 작용시키도록한 것으로 변체(11)는 변좌(12)의 외주에 형성한 후렌지부(18)와의 사이에 장치한 스프링(17)에 의하여 개변방향에 치우쳐 있게 되며, 상기한 역류조건하에서는 변체(11)는 스프링(17)의 탄지력에 저항하여 개변시키는 거이다.Next, in the embodiment shown in FIG. 3, the spring 17 is used to apply a slightly modified force to the deformable body 11. The deformable part 11 is formed on the outer periphery of the toilet seat 12. ) Is biased in the opening direction by the spring 17 provided between and, and under the above-mentioned reverse flow condition, the changing body 11 is changed to resist the holding force of the spring 17.

이 경우에도 제1실시예와 같이 기능하게 되는 바 제1실시예의 것은 이 제2실시예의 것에 비하여 개변 탄지력을 적게 설정할 수 있게 되어 역지변 기능 즉, 응답성에 있어서 우수한 것이 된다.Also in this case, the same function as in the first embodiment can be achieved, so that the modified fingering force can be set less than that in the second embodiment, which is excellent in the reverse displacement function, that is, in response.
