Description

동파방지용 수도계량기 {water meter to prevent being frozen to burst}Freezing Water Meter {water meter to prevent being frozen to burst}

본 발명은 동파방지용 수도계량기에 관한 것으로, 더욱 상세하게는 수도 계량기 내부에 에어쿠션과 완충스프링을 설치하여 수도의 동결에 의한 물의 부피팽창으로 인한 파손을 방지하는 수도계량기를 제공하는데 있다.The present invention relates to a freeze-prevention water meter, and more particularly, to provide a water meter to prevent damage due to volume expansion of water by freezing the water by installing an air cushion and a buffer spring inside the water meter.

일반적으로 기온이 섭씨 영하 5도 이하로 떨어지는 동절기가 2, 3일 지속되면 외기에 노출된 파이프나 옥상층에 설치한 물탱크, 아파트 또는 단독주택의 수도계량기 등 집안의 용수와 관련된 시설이 얼어 터지는 동파현상 발생이 빈번하다.In general, when the temperature lasts for two or three days when the temperature drops below 5 degrees Celsius, facilities related to water in the house, such as pipes exposed to the outside air, water tanks installed on the rooftop, and water meters in apartments or detached houses, freeze. Freezing occurs frequently.

이런, 동파현상의 전단계는 용수배관의 어디선가 얼기 시작해 물의 흐름이 끊기는 것이다. 용수가 나오지 않으면 즉시 사용 가능토록 긴급조치가 필요하다.This preliminary step is to freeze somewhere in the water pipe and stop the flow of water. If no water is available, urgent action is needed to ensure immediate use.

이러한, 동파를 방지하기 위해서 노출된 수도관을 보온재를 시공하거나 헌옷, 천등을 이용하거나 니크롬선 이나 정온전선과 같은 열선을 이용하여 동파를 방지하였다.In order to prevent such freezing, the exposed water pipes were prevented by installing thermal insulation material, using old clothes, cloth, or using a heating wire such as a nichrome wire or a constant temperature wire.

상기와 같이 수도관의 동파에 대비한 동파방지장치는 다양하게 개발되어 왔으나, 동파사고에 의한 누수등 피해 면에서 지상수도관 동파사고 시보다 심각한 수도계량기 동파사고에 대해서는 수도계량기가 지하에 설치되어 있다는 이유로 등한시 되어 왔기 때문에 수도계량기 동파사고 발생이 늘어나고 있는 실정이었다.As mentioned above, the freeze protection device for the freezing of water pipes has been developed in various ways. However, the water metering device is more severe than the ground water pipe freezing accident in terms of damages such as water leakage. Since it has been neglected, the occurrence of freezing accidents in water meters has been increasing.

그래서, 현재 우리나라의 기후와 주택구조상 수도계량기의 동파를 방지하기 위하여 종래 기술의 동파방지용 수도계량기는 건물 외부의 지하에 설치하고 열선을연결하여 보호하거나 수도계량기 보호통에 백열전구를 설치하여 보온하거나 헌옷이나 톱밥, 왕겨 등을 계량기 보호통에 넣어 보온처리하여 사용하고 있으나 동절기 기상이변으로 인해 보온처리한 수도계량기라도 예고없는 수도계량기 동파발생이 매년 증가하고 있으며, 수도계량기의 관리의무가 수용가에게 있다는 것이 법으로 정해져 자연재해에 의한 수동계량기에 동파의 경우라도 수용가는 계량기 교체비용과 설치비용 또 동파에 따른 누수요금까지 부담하여야 하고 단수에 따른 불편을 수용가는 감수해야 하며 매년 수도계량기의 동파에 따른 부담금 납부거부 민원발생이 증가되고 있으나 예고없는 계량기 동파에는 대책이 없는 실정이었다.Therefore, in order to prevent the freezing of the water meter in the current climate and housing structure of our country, the freezing water meter of the prior art is installed in the basement outside of the building and connected by heating wire to protect it or by installing incandescent bulbs in the water meter protector to keep warm or old clothes. Insulating sawdust, rice husk, etc. are put in the protective container and used for heat treatment.However, even if the water gauge kept warm due to extreme weather in winter, the occurrence of freezing water meter is increasing every year, and the duty of managing water meter is on the customers. Even in the case of freezing in manual instruments caused by natural disasters, the customer should bear the cost of replacing the meter, installation cost, and the leakage fee according to the freezing frequency. Rejection complaints are on the rise Meters freezing or without prior notice, the situation was no measure.

또한, 종래 기술의 동파방지용 수도계량기는 열선이나 백열전구를 설치할 시에는 따로 전기를 연결하여야 하고 내부 습기에 의해 누전이 발생하거나 단선으로 인하여 기능을 상실하는 문제점이 있었다.In addition, the conventional freeze-prevention water meter has a problem in that when the heating wire or incandescent lamp is installed, electricity must be connected separately, and a short circuit occurs due to internal moisture or a loss of function due to disconnection.

아울러, 헌옷이나 톱밥, 왕겨 등으로 보온처리를 할 시에는 습기를 흡수하여 함께 동결되므로 보온처리의 효율이 저하되고 물이 녹아도 습기를 내재한 보온재가 녹지 않아 오히려 동파를 촉진하는 문제점이 있었다.In addition, when the warming treatment with old clothes, sawdust, chaff, etc. absorbs moisture and freezes together, so the efficiency of the warming treatment is lowered, and even if the water melts, there is a problem of promoting the freezing rather than melting the heat-insulating material.

이와 같은 문제점을 해결하기 위하여 안출된 본 발명의 주 목적으로 하는 바는 수도계량기 내부에 에어쿠션을 설치하여 에어쿠션층을 계량부와 유수부 사이에 형성하여 동결에 의한 물의 팽창과 해동에 의한 물의 수축으로 발생되는 부피의 변위에 따른 부피압을 내부에 공기가 채워진 에어쿠션의 유격으로 자동 조절하여 수도계량기의 동파를 방지함으로써 동파로 인한 누수 및 수도계량기 교체에 따른 비용을 절감하여 경제성을 향상시키는 수도계량기를 제공하는데 있다.In order to solve the above problems, the main object of the present invention is to install an air cushion inside the water meter and to form an air cushion layer between the metering part and the flowing part to freeze the water by expansion and thawing. It automatically adjusts the volume pressure according to the displacement of the volume caused by the contraction to the gap of the air cushion filled with air to prevent freezing of the water meter, thereby reducing the cost of water leakage due to freezing and replacing the water meter, thereby improving economic efficiency. To provide a water meter.

본 발명의 다른 목적은 수도계량기의 덮개부에 완충스프링을 설치하여 에어쿠션에서 흡수한 부피압보다 큰 부피압의 변화를 이차적으로 흡수하므로 수도계량기의 동파를 방지하는데 있다.Another object of the present invention is to prevent the freezing of the water meter because the buffer spring is installed on the cover portion of the water meter to absorb the change of the volume pressure larger than the volume pressure absorbed by the air cushion.

본 발명의 다른 목적은 수도계량기 표시창의 유리부분에 방탄필름을 부착하여 강도를 강화시킨 수도계량기를 제공하는데 있다.Another object of the present invention is to provide a water meter which is strengthened by attaching a ballistic film to the glass portion of the water meter display window.

먼저, 수도관(1)으로 물이 유입되면 유수부(130)의 흡수공(132)으로 유입되어 배수공(133)으로 배수되면서 계량부(110)의 팬과 회전축을 회전시킨다.First, when water flows into the water pipe 1, the water flows into the absorption hole 132 of the flowing water 130 and is drained into the drain hole 133, thereby rotating the fan and the rotating shaft of the metering unit 110.

이렇게, 계량부(110)의 회전축(112)이 회전되면 맞물린 기어유닛(113)이 회전하면서 카운터(114)를 구동하여 수돗물의 유입량을 계량한다.As such, when the rotating shaft 112 of the metering unit 110 is rotated, the engaged gear unit 113 rotates to drive the counter 114 to measure the amount of tap water inflow.

이런, 수도계량기(100)가 이상기후로 인하여 기온이 하강하면 유수부(130)에 물이 동결하면서 부피가 커지는 부피압이 증대하고 부피압에 따라 유수부(130)의상부에 형성된 에어쿠션(116)을 상부로 밀어올리게 된다.When the temperature is lowered due to the abnormal weather, the water meter 100 increases the volume pressure of the water flowing through the freezing portion 130 while increasing the volume pressure and forming an air cushion formed on the upper portion of the flowing portion 130 according to the volume pressure. 116 is pushed upwards.

이렇게, 물의 동결로 부피압이 증대하면 에어쿠션(116) 내부에 형성된 에어챔버(116a)의 공기가 에어관(116c)으로 유출되면서 자동으로 유격이 형성되어 부피압으로 인한 손상을 방지한다.As such, when the volume pressure increases due to freezing of water, the air in the air chamber 116a formed inside the air cushion 116 flows out into the air pipe 116c, thereby automatically forming a clearance to prevent damage due to the volume pressure.

상기 물의 동결로 인한 부피압이 증가하여 에어쿠션(116)의 유격보다 커질 때는 덮개부(120)의 금속판(123)과 덮개(121)의 사이에 형성된 완충스프링(122)의 탄성력에 의해서 부피압의 증가분을 완충하여 수도계량기(100)의 파손을 방지한다.When the volume pressure due to freezing of the water increases and becomes larger than the clearance of the air cushion 116, the volume pressure is caused by the elastic force of the buffer spring 122 formed between the metal plate 123 and the cover 121 of the cover part 120. By buffering the increase of to prevent the breakage of the water meter (100).

이상기후가 끝나고 물이 해동되면 덮개부(120)의 완충스프링(122)과 계량부(110)의 에어쿠션(116)이 원상태로 복귀하여 정상적으로 수도계량기(100)가 작동한다.When the abnormal weather is over and the water thaws, the buffer spring 122 of the cover portion 120 and the air cushion 116 of the metering unit 110 is returned to its original state, and the water meter 100 normally operates.

따라서, 수돗물의 유입량을 계량하는 수도계량기(100)의 하부에 형성된 유입부(130)에서 물이 동결되어 증가하는 부피압을 계량부(110)의 에어쿠션(116)과 덮개부(120)의 완충스프링(122)으로 흡수하여 수도계량기(100)의 동파를 방지한다.Therefore, the water volume is frozen in the inlet portion 130 formed in the lower portion of the water meter 100 to measure the inflow rate of the tap water to increase the volume of the air cushion 116 and the cover portion 120 of the metering unit 110 Absorbed by the buffer spring 122 to prevent freezing of the water meter 100.
