이 고안은 가정용 수도미터의 입수구측에 설치하여 사용하는 수도미터용앵글밸브에 관한 것으로서, 밸브케이싱내에 장설한 스트레이너의 청소 또는 교체작업을 용이하게 할 수 있도록 함과동시에, 지수콕과 스트레이너 사이에는 스트레이너 내부에서 승강작동하는 역지변을 설치하여 단수(斷水) 되었을때 가옥내에 배관된 수도관에 잔류하는 물이 수도미터를 통하여 역류되는 것을 방지하므로서 수도미터가 정확한 계량작용을 나타내도록 하기 위한 것이다.The present invention relates to an angle valve for a water meter installed on the inlet side of a household water meter, and to facilitate the cleaning or replacement of the strainer installed in the valve casing. In order to prevent the water meter from flowing back through the water meter, the water meter shows accurate metering action by installing a reverse valve that moves up and down inside the strainer.

종래의 수도미터용 지수밸브는 일반적으로 수도가 단수 되었다가 다시 송수될 때에 수도관내의 공기가 수도미터를 통과하는 것을 방지할 목적으로 기수(氣水) 분리장치를 설치하고, 여과통의 중앙부에 통수관을 형성하는 것이었으므로, 구조가 복잡할 뿐 아니라, 단수시에는 가옥내수도관의 물이 수도미터를 거쳐 역류하게 되어 수도미터의 계량오차를 발생시키게 되는 것이었으며, 여과통내부에 설치된 역지변을 영구자석에 의하여 자기력으로 흡인 폐쇄시키도록 한것(실용신안출원공개 제95-1641호)은 수도관내 철분이 자석에 흡착되어 밸브작용 방해하는 등의 결점이 있는 것이다.Conventional water metering water valves generally have a water separator for the purpose of preventing the air in the water pipes from passing through the water meter when the water is singled out and then re-watered. As it was a pipe, it was not only complicated in structure but also water in the house water pipe flowed back through the water meter to generate a metering error in the water meter. The suction closure by magnetic force by the permanent magnet (Utility Model Application Publication No. 95-1641) has a drawback that iron in the water pipe is adsorbed to the magnet and interferes with the valve action.

이 고안은 이와같은 종래의 지수밸브가 갖는 결점을 제거하고, 근래에는 급수사정에 호전되어 단수되는 일이 거의 없는 점을 감안하여 기수분리장치 대신에 여과면적을 넓게 형성시킴과 동시 역류방지변이 스프링에 의하여 탄발되도록 설치하여 수도미터의 계량오차를 감소시키도록 한 것으로 이하 도면에 따라 상세히 설명하면 다음과 같다.This design eliminates the drawbacks of such conventional water valves, and in recent years, has improved the water supply situation and rarely cuts water. It will be installed to be shot in such a way to reduce the metering error of the water meter will be described in detail according to the following drawings.

밸브케이싱(1)의 하측부에 형성된 입수구(2)에는 지수콕(3)을 설치하고, 밸브케이싱(1)의 측면부와 상면부에는 각각 출수구(4)와 정비구(5)를 형성하여 밸브케이싱(1) 내부에 여과망체(6)을 설치하도록 한 것에 있어서, 입수구(2)의 내측에 형성된 밸브시이트(8)와 정비구(5) 사이에는 내측 프래임(9)이 형성된 여과망체(6)를 삽입하여 정비구(5)의 내경부에 나사결합되는 캡보울트(10)로 고정되게 설치하였으며, 여과망체(6)의 내측 공간부로는 밸브시이트(8)의 통수공(7)을 개폐하는 역지변(12)의 안내축(11)을 상향되게 돌출시켜 안내축(11)이 여과망체(6)의 내측프래임(9)과 역지변(12) 사이에는 스프링(13)을 개재시켜 스프링(13)의 탄력으로 역지변(12)이 통수공(7)을 닫아 입수구(2)와 출수구(4) 사이를 차단하도록 구성하여서 된 것이다.The water inlet 2 formed in the lower part of the valve casing 1 is provided with a water stopcock 3, and the water outlet 4 and the maintenance tool 5 are formed in the side part and the upper part of the valve casing 1, respectively. In the case where the filtering net body 6 is provided inside the casing 1, the filtering net body 6 having the inner frame 9 formed between the valve seat 8 and the maintenance tool 5 formed inside the water inlet 2 is provided. ) Was installed to be fixed by the cap bolt 10 which is screwed into the inner diameter of the maintenance tool (5), opening and closing the water hole (7) of the valve seat (8) to the inner space of the filter network (6) The guide shaft 11 of the reverse side (12) to be projected upward so that the guide shaft 11 is interposed between the inner frame (9) and the reverse side (12) of the filter net body 6 through the spring (13) By the elasticity of (13), the reverse side 12 is configured to close the water passage (7) to block between the inlet (2) and the outlet (4).

이와같이 구성된 이 고안은 제3도에 도시한 바와같이 수도미터의 입수구측에 연결하여 사용하는 것으로서, 지수콕(3)을 돌려 통수되게 한 후, 수도꼭지를 열어 물을 사용하게 되면, 이제까지 스프링(13)의 탄력으로 닫혀있던 역지변(12)이 입수구(2)측과 출수구(4)측의 수압차로 인하여 스프링(13)을 밀어올리면서 열리게되고, 물은 여과망체(6) 속으로 진입하여 여과된 후 출수구(4)로 유출되는 것인바, 물을 사용한후 수도꼭지를 잠그면, 입수구(2) 측과 출수구(4)측의 수압차가 없어지므로 인하여 역지변(12)은 스프링(13)의 탄력을 받아 밸브시이트(8)에 밀착되면서 통수공(7)을 폐쇄하게 되는 것이고, 이후 원수관측에 단수현상이 발생하더라도 가옥내에 배관된 출수구(4)측의 물은 역지변(12)의 차단작용으로 인하여 입수구(2) 측으로 역류하는 것을 방지하므로서 수도미터의 역회전으로 인한 계량오차의 발생을 방지할 수 있을 뿐 아니라, 역지변(12)에 의한 역류방지작용으로 여과망체(6)내에 잔류하는 이물질 역시 역지변(12)에 막혀 입수구(2)측으로 역유입되는 일이 없어 수도미터를 통과한 이물질이 다시 수도미터에 역유입하는데 기인되는 수도미터의 고장발생율을 감소시켜 정확한 계량작용을 나타낼수 있게 되는 것이다.This design, which is configured in this way, is connected to the water inlet side of the water meter as shown in FIG. 3, and after turning the water cock 3 to pass water, opening the faucet and using water until now, the spring (13) The reverse side 12, which was closed by the elasticity of), is opened by pushing the spring 13 due to the water pressure difference between the inlet port 2 side and the outlet port 4 side, and water enters the filtration net 6 and is filtered. After the water is discharged to the outlet (4) bar, and after using the water to lock the faucet, because the water pressure difference between the inlet (2) side and the outlet (4) side is eliminated, the reverse side 12 is the elasticity of the spring (13) The water supply hole 7 is closed while being closely adhered to the valve seat 8, and even if water flow occurs in the raw water pipe side, the water on the outlet port 4 side of the house is blocked by the reverse displacement 12. Because it prevents backflow to the inlet (2) side Not only can the measurement error due to the reverse rotation of the water meter be prevented, but also the foreign matter remaining in the filter net 6 due to the reverse flow prevention action caused by the reverse displacement 12 is also blocked by the reverse displacement 12 so that the water inlet 2 Since no foreign matter flows back to the water side, foreign matter that has passed through the water meter is reduced in the rate of failure of the water meter caused by the inflow back to the water meter, thereby exhibiting accurate metering action.

또한 여과망체(6)에 의하여 여과된 이물질은 항상 여과망체(6) 내부에 잔류하게 되는 것이므로 수시로 밸브케이싱(1)의 상방으로 개구된 정비구(5)의 캡보울트(10)를 풀어 정비구(5)를 통하여 여과망체(6) 및 역지변(12)을 들어내어 청소하거나 패킹 등을 갈아 끼울 수 있는 것이므로 부품의 교체와 유지관리가 용이할 뿐 아니라, 역지변(12)의 안내축(11)이 여과망체(6)의 내측프래임(9)으로 지지되어 있고, 역지변(12)과 내측프래임(9) 사이에는 스프링이 탄발상태로 설치되어 있는 것이어서, 수도관내에 부유하는 철분등이 역지변(12)의 안내축(11)에 부착되어 안내축(11)의 승강작용을 방해하거나, 역지변의 개폐작용을 방해하는 구성부분이 없어 원활한 밸브개폐작용을 나타내게 되는 것이다.In addition, since foreign substances filtered by the filter net 6 always remain inside the filter net 6, loosen the cap bowl 10 of the maintenance tool 5 opened upward from the valve casing 1 from time to time. (5) it is possible to lift and clean the filter net body 6 and the reverse finger (12), or to replace the packing, so that not only easy replacement and maintenance of parts, but also the guide shaft of the reverse finger (12) ( 11) is supported by the inner frame 9 of the filtration net 6, the spring is installed between the reverse side 12 and the inner frame 9 in a springing state, so that the iron and the like floating in the water pipe Attached to the guide shaft 11 of the reverse side 12 is to hinder the lifting action of the guide shaft 11, or there is no component that prevents the opening and closing action of the reverse side will exhibit a smooth valve opening and closing action.
