Abstract
Description
온도가 높은 여름이면 수돗물들이 얼지 않았고, 수돗물을 계량하는 계량기의 동파도 문제되지 않았으나, 추운 겨울이 되면 물의 온도를 떠나, 수도계량기에서 가정 내로 공급되는 수도관 속의 물들이 수도관들 밖과의 온도차이로 물의 밀도가 변화되어서, 그 수돗물의 밀도에 따르는 힘이 다른 곳으로 전달되어야하는 것이다.When the temperature is high in summer, the tap waters did not freeze, and the freezing frequency of the water meter was not a problem, but in the cold winter, the water inside the water pipe supplied from the water meter to the home by the water meter is different from the outside of the water pipes. The density of the water is changed so that the force of the tap water's density must be transferred elsewhere.
계량기를 통과한 수돗물들이 다시 역류를 해서 원수자원의 공급처인 상수도 본래의 공급처로 돌아가면 좋겠지만, 계량기를 통과한 수돗물들이 다시 계랑기를 통과하기 어렵다. 그래서 그 계량기를 통과해서 가정집으로 공급되는 수도관 속의 수돗물들이 수도관 주위의 낮은 온도로 늘어난 자기의 용적을 버릴 때가 없으니, 그 계 내에서 가장 연약한 파손이 잘 되는 「수도계량기」의 몸체에 전달하고 만다.Tap water passing through the meter would flow back to the water supply source, but the tap water passed through the meter would not be able to pass through the meter again. Therefore, the tap water in the water pipe that passes through the meter to the home is never discarded by the low temperature around the water pipe, so it is delivered to the body of the most fragile water meter in the system.
본 발명의 장치의 속을 압력을 지정해 두면, 날씨가 추운 겨울이 되어도, 조절 압력이상이 되면 자동으로 수도계량기와 가정집으로 공급되는 밸브사이에 설치되어있는 본 발명 내의 용추철의 힘(지정압력)이, 그 배관내의 압력을 결정하면 지정압력이상이 되면 자동으로 본 발명의 장치가 파열이 되어서 수도 계량기가 파열되는 것을 막는다.When the pressure of the apparatus of the present invention is designated, the force (specified pressure) of the hot-spring in the present invention is installed between the water meter and the valve supplied to the home automatically when the temperature is over the control pressure even when the weather is cold winter. When the pressure in the pipe is determined, the apparatus of the present invention automatically ruptures when the pressure exceeds the specified pressure, thereby preventing the water meter from rupturing.
..
(도 1)은 땅속에 설치 매몰되어 있는 수도계량기의 절단면도.1 is a cross-sectional view of the water meter installed buried in the ground.
(도 2)는 수도관내의 모든 높은 압력에도 설치자의 조정압력이 되면 자동으로 수도관 속의 압력을 조절해 주는 장치의 내부도이다.2 is an internal view of a device that automatically adjusts the pressure in the water pipe when the pressure of the installer is adjusted even at all high pressures in the water pipe.
상수도를 가정집에 공급시키는데 있어서, 각 집마다 수돗물의 사용량이 다르기에 수돗물 사용량을 검침해서 수돗물에 사용에 따르는 요금을 부과하기 위해서 수돗물의 사용량을 검침하려고 수돗물의 계량기를 설치한다.In the supply of tap water to homes, the amount of tap water used is different in each house, so tap water meters are installed to measure the amount of tap water used to check the amount of tap water used and to charge a fee for use.
그러나 따스한 여름이면 수돗물이 얼지 않기에 수도계량기가 동파되는 일이 없으나, 추운 겨울이 되면 수도관내에 수돗물의 「3.98도」일 때, 물의 밀도가 가장 높아, 물의 부피가 작지만, 3.98도 이하가 되면 오히려 수돗물의 부피가 커지는 것이니, 비교적 응력이 큰 수도관이나, 다른 곳으로는 파열되지 못하고, 응력이 비교적 낮은 수도계량기내 응력이 약한 곳으로 차가운 물의 압력이 작용하니, 그 약한 곳이 파열되는 것이다.However, in warm summer, the tap water does not freeze, so the water meter does not freeze, but in the cold winter, when the tap water is `` 3.98 degrees '', the density of water is the highest and the volume of water is small, but it is less than 3.98 degrees. Rather, the volume of the tap water is increased, so that the water pipes with relatively high stress or other places cannot be ruptured, and the cold water pressure is applied to the place where the stress is weak in the water meter where the stress is relatively low.
그러나 그 파열되는 압력보다 지정한 약간 낮은 압력에도 (도1)의 위치에 (도 2)의 본 발명의 장치를 설치해서, 그곳을 통해서 차가운 수돗물이 밖으로 배출되게 하면, 수도관 다른 계에 온도차이로 인한 수돗물의 부피가 늘어나는 것을 그곳으로 분출시켜서 계량기동파를 막는 것이다.However, if the apparatus of the present invention is installed in the position of (Fig. 1) at a slightly lower pressure than the bursting pressure, and the cold tap water is discharged out there, the temperature difference in the water pipe other system The increase in the volume of tap water is ejected there to block the metering waves.
(효과1): 추운 겨울이 되면 넓은 수도관들의 온도차이로 해서 생긴 압력이 수도관 중의 계중에서 가장 응력이 낮은 곳으로 동파는 것이다.( Effect 1 ): In cold winters, the pressure caused by the temperature difference between wide water pipes is freezes to the lowest stress in the water pipe system.
대기 중으로 나온 수도관들은 수도관들이 얼지 않게 동여 메고 있었다.The water pipes that came out of the atmosphere were holding them freeze.
그러니 그 수돗물을 공급시키는 관들은 비록 얼지는 않겠지만, 온도가 낮아서 발생한 수돗물의 부피의 늘어남을 그 계 내에서 가장 응력이 낮은 곳으로 분출하려고 하기에 가장 응력이 낮은 계량기내의 동파를 방지한다.So the pipes supplying the tap water, although not frozen, try to eject the increase in volume of the tap water caused by the lower temperature to the lowest stress point in the system, thus preventing freezing in the lowest stress meter.
(효과2): 날씨가 추운 겨울이면 일반 가정에서는 수도계량기에서 동파가 많이 일어난다는 것을 알기에, 그 계량기속에 보온장치를 해 두었던 것이나, 그러한 것을 하지 않아도 수도관이나, 수도계량기 동파가 없어서 추운 겨울에도 사람들이 수돗물을 원활하니 사용할 수 있다.( Effect 2 ): When the weather is cold in winter, we know that there is a lot of freezing in the water meter in ordinary households. People can use tap water smoothly.
(효과3): 수도계량기의 동파로 인한 재질 낭비를 막는다.( Effect 3 ): Prevents material waste due to freezing of water meter.
(효과4): 아무리 날씨가 추워도 수도관이나, 수도계량기 동파가 없다는 것을 시민들이 잘 알기에 마음이 편하다.( Effect 4 ): No matter how cold the weather, it is easy for citizens to know that there are no water pipes or water meter freezing.
