본 발명은 수도미터기 동파시 투시창(또는 유리면)등의 파손 및 훼손등을 방지하는 장치에 관한 것으로, 더욱 상세하게는 수도미터기 내부의 상부작동조립체의 숫자판 상부측에 부피팽창흡수공간부를 형성하여, 수도미터기 내부의 물이 얼어서 부피가 팽창해도 늘어난 부피를 흡수할 수 있어 수도미터기의 투시창(또는 유리면)과 조립부품 등의 파손을 방지할 수 있도록 하고, 동파시에도 물과 글리세린이 외부로 유출되지 못하도록 한 수도미터기용 동파방지 장치에 관한 것이다.The present invention relates to a device for preventing breakage and damage of the water meter glass see-through window (or glass surface), and more specifically, by forming a volume expansion absorption space portion on the upper side of the number plate of the upper operation assembly inside the water meter, As the water inside the water meter freezes, it can absorb the increased volume even if the volume expands, preventing damage to the sight glass (or glass surface) and the assembly parts of the water meter. The present invention relates to a freeze protection device for a water meter.

종래에는 동계절에 수도미터기내의 물이 얼기 시작하면 부피가 팽창하면서 약한 곳을 밀게 되는데, 통상의 수도미터기 내에는 부피 팽창에 상응하여 부피 팽창을 흡수할 수 있는 곳이 없으므로, 주로 최상부측 1차 투명판과 투시창(또는 유리면)과 감속기어, 투명판 등이 잘 파손되고, 특히 1차 투명판과 투시창(또는 유리면)이 파손되면 계수부 내부와 투시창(또는 유리면)사이의 얇은 공간에 투입시킨 글리세린이 외부로 유출되어 수도미터기가 계수 작동하지 못하게 되고, 수돗물이 외부로 흘러나와 많은 생활의 불편과 재 설치 작업에 따른 많은 시간과 비용이 소요되었다.
또한, 부피팽창흡수공간부를 만들기 위해 에어백 등을 설치한 것이 있으나, 이는 약간의 신축 작용은하나 에어백 내부의 공기가 유출입할 수 없으므로 에어백의 형상은 변할 지언정 팽창부피를 제대로 흡수할 수 없어 마찬가지로 동파되고, 국내 등록특허공보 10-0547511호와 같이 수도미터기의 유리면 대신에 강화유리보다 강한 폴리카보네이트 씨트를 장착시키고, 합성수지 투명판이 폴리카보네이트 씨트와 접촉지지되게 설치하여 합성수지 투명판이 동파되지 않도록 한것이 있었으나, 이는 설혹 합성수지 투명판이 폴리카보네이트 씨트의 지지에 의해 파손되지 않는다 하더라도 물이 얼어 부피가 팽창하면 팽창되는 얼음부피를 수용할 곳이 없으므로 수도미터기 내부에 설치된 기어, 숫자판, 계수부 등의 많은 조립 부품과 그 사이를 밀게 되므로 많은 조립부품이 훼손 또는 파손되어 기능이 정지되므로 재 설치해야 되고, 심한 경우에는 수도관까지 동파되어 더 많은 피해가 발생하는 문제점 등이 있었다.Conventionally, when water in a water meter starts to freeze during the winter season, the volume expands and pushes a weak place. In a conventional water meter, since there is no place that can absorb the volume expansion corresponding to the volume expansion, it is mainly a first-order primary. The transparent plate, the sight glass (or glass surface), the reduction gear, the transparent plate, etc. are damaged well, and in particular, if the primary transparent plate and the sight glass (or the glass surface) are broken, the transparent plate and the sight glass (or glass surface) are damaged. Glycerin was leaked to the outside, which prevented the water meter from counting, and the tap water flowed out, causing a lot of inconvenience and re-installation.
In addition, airbags and the like are installed to make the volume expansion and absorption space part. However, the airbags are slightly stretched, but since the air inside the airbags can not flow in and out, the shape of the airbags cannot be absorbed properly, but the shape of the airbags can be absorbed. Instead of the glass surface of the water meter as shown in Korean Patent Publication No. 10-0547511, a polycarbonate sheet stronger than tempered glass was installed, and the transparent resin plate was installed so as to be in contact with the polycarbonate sheet so that the transparent resin plate was not frozen. Even if the synthetic resin transparent plate is not damaged by the support of polycarbonate sheet, there is no place to receive the ice volume that expands when the water freezes and the volume expands, so there are many assembly parts such as gears, plates, counters, etc. installed inside the water meter. Because it pushes in between The assembly parts are damaged or damaged, so the function is stopped and must be re-installed. In severe cases, there were problems such as freezing of water pipes causing more damage.

먼저, 본 발명의 조립과정을 살펴보면, 수도미터기(1)의 하부 외갑체(3)내에 하부내갑체(28)와 임펠러(27) 및 상부 내갑체(26)를 삽입조립시키고, 상부 내갑체(26)내에는, 숫자판(20)의 주연부를 2차 투명판(15)의 돌부테(37)와 하부 1차 투명판(19)의 형합돌부테(17)로 밀폐시키고, 1차 투명판(19), 또는 2차 투명판(15)상부측에 투명승강판(14)을 장착시킨 상부작동조립체(18)를 상기, 상부 내갑체(26)내에 넣어 조립장착하고, 차례로 조립시킨 상기 하부 내갑체(26)와 상부 내갑체(26)의 전체를 수도미터기(1)의 하부 외갑체(3)내에 넣고, 그 위에 투시창(또는 유리면)(13)또는 투시창(13)과 확대경을 장착홈(38)에 장착시킨 장착고정캡(4)을 올려놓고, 그 위에 금속재인 상부 외갑체(2)를 씌우고 체결고정시키면 본 발명 수도미터기의 조립이 완성된다.First, referring to the assembly process of the present invention, the lower inner shell body 28, the impeller 27 and the upper inner shell body 26 are assembled into the lower outer shell body 3 of the water meter 1, and the upper inner shell body ( In 26, the peripheral edge of the numeric keypad 20 is sealed with a dolbute 37 of the secondary transparent plate 15 and a molded dolbute 17 of the lower primary transparent plate 19, and the primary transparent plate ( 19) or the upper operation assembly 18 in which the transparent lifting plate 14 is mounted on the upper side of the secondary transparent plate 15 in the upper inner body 26 to be assembled and mounted, and then assembled in turn. The whole of the upper body 26 and the upper inner body 26 is placed in the lower outer body 3 of the water meter 1, and a viewing window (or glass surface) 13 or a viewing window 13 and a magnifying glass are mounted thereon. 38) Put the mounting fixing cap (4) mounted on the top, put the upper outer shell body (2) made of metal on the fastening and fastening to fix the assembly of the water meter of the present invention.

이와같이 조립장착된 본 발명 수도미터기(1)는 상부 외갑체(2)를 체결조립하면서 상부 외갑체(2)의 걸림환턱(32)이 상부작동조립체(18)의 주연부 상측을 압압하게 되므로 하부 내갑체(3)에 삽입장착된 상부작동조립체(18)의 주연부측에 장착시킨 오링(31)을 압압하게 되어, 상부작동조립체(18)의 주연부측으로 물이 누수되지 못하게 된다.The water meter 1 of the present invention is assembled and mounted in such a manner that the locking ring jaw 32 of the upper outer shell 2 presses the upper edge of the upper operation assembly 18 while assembling and assembling the upper outer shell 2. The O-ring 31 mounted on the periphery of the upper operation assembly 18 inserted into the upper body 3 is pressed, so that no water leaks to the peripheral part of the upper operation assembly 18.

또한, 상부작동조립체(18)의 상면측에 밀착장착시킨 투명승강판(14)의 신축(고무재)부(41)에 의하여는 상부작동조립체(18)의 주위와 상면측으로 물이 유수되거나 누수되지 못하게 하므로, 설혹 동파된다 하여도 투명신축판(14)이 늘어날지언정 물과 글리세린이 외부로 흐르지 않게 된다.In addition, water is leaked or leaked to the periphery and the upper surface side of the upper operating assembly 18 by the elastic (rubber material) portion 41 of the transparent lifting plate 14 closely attached to the upper surface side of the upper operating assembly 18. Because it does not, even if freezes even if the transparent stretch plate 14 is stretched, but water and glycerin does not flow to the outside.

또한, 계수부(22)의 숫자판(20) 주연부를 2차 투명판(15)의 돌부테(37)와 하부 1차 투명판(19)의 형합돌부테(17)로 밀폐시켰으므로 글리세린(25)의 투입량이 작아지게되고, 공기의 유출입이 없어져 숫자판 상측 투명판에 수증기가 끼지 않게 되어 숫자판을 항상 선명하게 사용할 수있으며, 설혹 1,2차 투명판(19)(15)이 동파되어도 글리세린이 수돗물에 유입되거나 외부로 유출되지 않게 된다.In addition, since the periphery of the number plate 20 of the counter 22 is sealed with the dobute 37 of the secondary transparent plate 15 and the mold dobute 17 of the lower primary transparent plate 19, glycerin (25) ), The input amount is reduced, and air flow is eliminated, so that water vapor is not caught on the upper transparent plate so that the number plate can always be used clearly, and even if the first and second transparent plates 19 and 15 are freezing, It does not enter tap water or outflow.

또한, 투명승강판(14)의 신축(고무재)부(41)의 재질을 일정한 수압을 견디는 재질로 형성하였으므로, 통상적인 수압상태에서는 투명승강판(14)이 신축작용하지 않게 되고, 물이 얼어부피가 팽창되는 경우에만 투명승강판(14)이 신축 작용하게 된다.In addition, since the material of the stretchable (rubber material) portion 41 of the transparent lifting plate 14 is formed of a material that withstands a constant water pressure, the transparent lifting plate 14 does not stretch and contract under normal pressure. The transparent lifting plate 14 is stretched only when the freezing volume is expanded.

또한, 수도미터기(1)내부의 물이 얼어 부피가 팽창하면 2차 투명판(15)의 구멍(16)(16')과 1차 투명판(19)의 구멍(34)(34')을 통해 부피가 팽창되어 오르면서 상측에 위치한 투명승강판(14)을 밀게 되고, 투명승강판(14)은 팽창된 부피만큼 상부측에 형성시킨 부피팽창흡수공간부(40)로 신축 팽창작용하게 되므로, 많은 조립부품과 투시창(13)등의 훼손 및 파손을 방지하게 된다.In addition, when the water inside the water meter 1 freezes and expands in volume, the holes 16 and 16 'of the secondary transparent plate 15 and the holes 34 and 34' of the primary transparent plate 19 are opened. As the volume is expanded and pushed up, the transparent lifting plate 14 located on the upper side is pushed, and the transparent lifting plate 14 expands and contracts to the volume expansion absorbing space 40 formed on the upper side by the expanded volume. To prevent the damage and damage of many assembly parts and see-through window 13, and the like.

또한, 수도미터기(1) 내의 물이 얼기시작하면 부피가 팽창되므로, 상부작동조립체(18)까지는 그대로 있고, 상부작동조립체(18)의 투명승강판(14)만이 신축작용하면서 부피팽창흡수공간부(40)에 있던 공기를 밀게 되는데, 공기가 빠지지 않게 되면 팽창 작용이 제대로 이뤄지지 않고 오히려 파손되나, 투명승강판(14)이 밀어낸 공기는 장착고정캡(4)의 공기구멍(6)(6')을 통해 장착고정캡(4)의 단턱부(7)상측 공간과 장착고정캡(4)의 최상면측 돌부(5)(5')사이 공간에 형성된 공기통로(36)를 통해 유출입작용할 수 있게 되므로, 부피팽창흡수공간부(40)에 있던 공기가 외부로 빠져나갈 수 있게 되어, 투명승강판(14)의 신축 팽창작용이 원활해지게 되고 투시창(유리면)(13)과 기어부(21). 계측침(23)등이 파손되지 않게 되고, 설혹, 일정길이(33)를 잘못측정하여(통상적으로 물이 얼면 9％ 정도의 부피가 증가함)제조되어 투시창(13)이 파손된다 하더라도 투명승강판(14)과 오링(31)에 의해 하부 외갑체(3)에 장착된 상부작동조립체(18)의 외부로 물이 외부로 누수되는 현상이 발생하지 않게 된다.In addition, since water in the water meter 1 starts to freeze, the volume expands, and thus remains until the upper operating assembly 18, and only the transparent lifting plate 14 of the upper operating assembly 18 expands and contracts, thereby expanding the volume expansion absorbing space. The air in the 40 is pushed, but when the air is not released, the expansion action is not properly performed, but rather the air is pushed out, but the air pushed out of the transparent lifting plate 14 is air holes 6 and 6 of the mounting fixing cap 4. ') Through the air passage 36 formed in the space between the upper end of the step portion (7) of the mounting fixing cap (4) and the top surface side protrusions (5) (5') of the mounting fixing cap (4) Since the air in the volume expansion absorbing space portion 40 can escape to the outside, the expansion and contraction action of the transparent lifting plate 14 is smooth and the viewing window (glass surface) 13 and the gear portion 21 ). The measuring needle 23 is not damaged, and even if the length 33 is erroneously measured (normally, when the water freezes, the volume increases by about 9%), the transparent window is damaged even if the viewing window 13 is broken. Water leakage to the outside of the upper operation assembly 18 mounted on the lower outer shell 3 by the steel plate 14 and the O-ring 31 is not generated.

이상에서 살펴본 바와같이, 본 발명은 물이 얼면 팽창되는 팽창부피를 수도미터기의 상부측 부피팽창흡수공간부에서 흡수할 수 있도록 하므로서, 수도미터기의 동파를 방지하고, 모든 기존 부품을 그대로 사용할 수 있고, 수도미터기의 성능도 동일하며, 수도미터기의 유로 공간도 그대로 유지되므로, 수도미터기의 성능과 품질이 그대로 유지되며, 제조작업이 간단해지고 제조비도 저렴하게 되고, 수도미터기 동파시에도 글리세린과 수돗물이 외부로 유출되지 않으며, 수도미터기 내의 각종 중요 부품의 훼손 및 파손을 방지시키는 효과가 있는 것이다.As described above, the present invention allows the expansion volume to be expanded when the water is frozen to absorb in the volume expansion absorption space portion of the upper side of the water meter, to prevent the freezing of the water meter, all existing parts can be used as it is In addition, the performance of the water meter is the same, and the flow path space of the water meter is maintained, so that the performance and quality of the water meter are maintained, manufacturing is simplified, manufacturing costs are low, and glycerin and tap water are kept at the same time. It does not leak to the outside, it is effective to prevent the damage and damage of various important parts in the water meter.
