본 고안은 수도계량기에 내장되는 상측커버의 직하방에 다공성 탄성체를 설치하여 동절기 계량기가 동파 하는것을 방지할 수 있도록 한 동파방지장치에 관한 것이다.The present invention relates to a freeze protection device for preventing the freezing of the winter meter by installing a porous elastic body directly below the upper cover built into the water meter.
종래에 일반적으로 사용되어온 수도계량기는 동절기의 동파방지를 위한 별도의 장치가 설치되어 있지 않기 때문에 계량기를 동파로부터 적절히 보호할 수 없었다.The water meter, which has been generally used in the past, could not adequately protect the meter from freezing because there is no separate device for freezing the winter.
일반적으로 계량기가 완전히 밀폐된 상태에서 계량기내로 유입된 물이 결빙할 때에는 계량기의 내부 체적보다 약 10% 정도 더 큰 체적이 필요하게 된다. 그러나 계량기 내의 체적은 한정되어 있으므로 결국 부족되는 체적만큼이 압력으로 작용하여 이 압력에 의해 계량기 상방에 복착된 유리등 약한 부분이 동파되며 따라서 물의 결빙시나 해빙시 계량기 내의 체적을 증감시키는 수단에 의해 동파를 방지할 수 있게 된다.In general, when water entering the meter freezes when the meter is completely enclosed, a volume of about 10% larger than the meter's internal volume is required. However, since the volume in the meter is limited, the volume that is lacking eventually acts as a pressure, and weak parts such as glass, which is stacked above the meter by this pressure, are freezing, and thus freezing by means of increasing or decreasing the volume in the meter during water freezing or thawing. Can be prevented.
본 고안은 이와같은 점에 착안하여 계량기의 내부에 흡수성(吸水性)이 없는 다공성 탄성체를 설치하고 수도물의 결빙시나 해빙시 이 다공성 탄성체가 수축 또는 팽창하면서 계량기내의 체적을 증감시켜 유리판등이 동파되는 것을 방지하도록 한 것인바, 이를 첨부된 도면에 의해 더욱 상세히 설명하면 다음과 같다.In view of this, the present invention installs a porous elastic body having no absorbency in the inside of the meter, and when the porous elastic body shrinks or expands during freezing or thawing of tap water, the volume in the meter increases and decreases, causing the glass plate to freeze. It is to prevent the bar, which will be described in more detail by the accompanying drawings as follows.
물유입구(2)와 토출구(3)를 가진 몸체(1)내에 상측커버(4)를 설치하고 그 상방에 투명유리(5)와 뚜껑(6)을 복착한 통상의 수도계량기에 있어서, 상측커버(4)의 저면에 다수개의 흡기공(7)을 천설하고 그 직하방에는 다수개의 측면 구멍(9)을 가진 하축커버 (8)를 설치함과 함께 상측커버(4)와 하측커버(8) 사이 공간부에 폴리우레탄등의 다공성 탄성체(10)를 내장하여서 된 것이다.In a conventional water meter in which a top cover 4 is provided in a body 1 having a water inlet 2 and a discharge port 3 and a transparent glass 5 and a lid 6 are disposed thereon, the top cover. A plurality of intake holes 7 are laid at the bottom of the upper part 4, and a lower shaft cover 8 having a plurality of side holes 9 is installed directly below the upper side of the upper cover 4 and the lower cover 8. It is made by embedding a porous elastic body 10 such as polyurethane.
이와같이 구성된 본 고안은 동절기 계량기 몸체(1)내에 물이 결빙할때 한정된 체적 때문에 발생하는 압력을 하축커버(8)내에 내장된 다공성 탄성체(10)가 흡수하여 투명유리(5)등의 동파를 방지할 수 있게 된다.The present invention configured as described above prevents freezing of transparent glass 5 by absorbing the pressure generated by the limited volume when water freezes in the winter meter body 1 by the porous elastic body 10 embedded in the lower shaft cover 8. You can do it.
즉, 계량기 몸체(1)내의 물이 결빙할 때 계량기 상방에서 발생하는 압량은 상측커버(4) 저면에 천공된 다수개의 흡기공(7) 및 하측커버(8) 외주연에 천공된 다수개의 구멍(9)을 통해 하측커버(8)내로 흡입되어 하측커버(8)내에 내장된 탄성체(10)(본 고안에서는 폴리우레탄을 예로 하였으나 고무공동 수축이 가능하고 흡수성이 없는 물질은 모두 동일한 효과를 나타낼 수 있음)를 압축하게 되고 결국 탄성체(10)의 압축된 체적만큼 계량기 몸체(1)내의 체적이 증가하게 되므로 투명유리(5)등이 동파하지 않게 되며 반대로 결빙된 물이 해빙될 때에는 하측커버(8)에 내장된 탄성체(10)가 팽창하여 원상복귀 되면서 계량기 몸체(1)내의 체적이 감소하게 되므로 투명유리(5)등의 파손을 방지할 수 있게 되는 것이다.That is, when the water in the meter body 1 freezes, the pressure generated above the meter may include a plurality of holes perforated in the outer periphery of the plurality of intake holes 7 and the lower cover 8 perforated in the bottom of the upper cover 4. (9) the elastic body 10 sucked into the lower cover 8 and embedded in the lower cover 8 (in this design, polyurethane is used as an example, but rubber joint shrinkage and non-absorbent material will all exhibit the same effect). And the volume in the meter body 1 is increased by the compressed volume of the elastic body 10, so that the transparent glass 5 does not freeze, and conversely, when the frozen water is thawed, the lower cover ( As the elastic body 10 embedded in 8) expands and returns to its original shape, the volume in the meter body 1 decreases, thereby preventing breakage of the transparent glass 5 and the like.
이와같이 본 고안은 수도계량기 몸체(1)내에 설치된 상측커버(4)에 흡기공(7)을 천공하고 그 하방에 탄성체(10)와 하측커버(8)를 설치하는 극히 간단한 구조에 의해 결빙시 또는 해빙시 몸체(1)내의 체적을 변환시킬 수 있으므로 동절기 계량기의 동파를 방지할 수 있는 효과가 있다.In this way, the present invention punctures the intake hole 7 in the upper cover 4 installed in the water meter body 1 and installs the elastic body 10 and the lower cover 8 under the extremely simple structure. Since the volume in the body (1) can be converted during thawing, there is an effect of preventing the freezing of the winter meter.
