Description

동파 방지용 수도 계량기 보호통{Water-proof meter dongpa protection tub}Water-proof meter dongpa protection tub}

본 발명은 수도 계량기의 동파 위험이 없도록 보호통을 구성시킨 수도 계량기 보호통에 관한 것인데 보다 구체적인 것은 수도 계량기가 장치되는 보호통내에 지하 침출수가 유입되는 것을 막아 동파 요소를 차단하고 급수수도관과 배출수도관 상단부 사이에 장치되는 수도계량기 접속부에 연결나사관과 체결나사를 사용하여 분해결합이 용이하게 함으로써 신속하고 편리한 탈부착이 달성되고 수도계량기를 검침할 때 그 숫자 파악이 편리하도록 검침용 볼록렌즈에 청소구를 첨부하여 검침이 편리하도록 만든 것이다.The present invention relates to a water meter protection container configured to protect the water meter so that there is no risk of freezing of the water meter. More specifically, it prevents the inflow of underground leachate into the protection tank in which the water meter is installed to block the freezing element and between the water supply pipe and the upper part of the discharge water pipe. Attaching a cleaning tool to the convex lens for meter reading to facilitate quick disassembly and detachment by using connecting screw pipe and fastening screw at the connection part of the installed water meter, and to easily grasp the number when reading water meter. The meter is made for convenience.

종래의 수도 계량기 보호통은 겨울철에 수도계량기가 동파되는 것을 방지하기 위해 계량기 보호통을 단열재로 구성하고 계량기 보호통 내부로 급수수도관과 배출수도관을 도입하여 상호간에 수도계량기 장치하고 있으나 수도계량기 보호통 속에 지하침출수가 유입되어 내부에 물이 고이게 되므로 기온이 급하강할 경우 내부의 물이 얼어서 보호통과 수도계량기의 동파를 초래하는 위험이 있었고, 수도계량기를 장착할 때 수도계량기의 입수구와 출수구를 급수수도관의 상단 개폐밸브출구와 배출수도관의 상단부 엘보 입구에 직접 체결 나사로 결속시키기 때문에 조립이 불편하고 결속부내의 방수가 여의치 않아 누수가 발생하는 문제가 있으며 수도계량기 검침시에 숫자가 잘 보이지 않아 볼록렌즈를 첨부하고 있지만 볼록렌즈 표면이 노출되어 있어서 성애가 끼이고 먼지가 앉아 검침시에 이를 일일이 닦아주어야 하는 불편이 있었다.Conventional water meter protection tank is composed of a water meter pipe and discharge water pipe inside the meter protection tank to prevent the freezing of the water meter in winter, and introduced the water supply pipe and the discharge water pipe to each other, but underground leachate in the water meter protection tank As the water flows in and the water builds up inside, there is a risk that the water inside freezes, causing freezing of the protection tank and water meter.When the water meter is installed, the water inlet and the water outlet of the water meter are opened and closed at the top of the water supply pipe. Because the fastening screw is directly connected to the valve outlet and the upper elbow inlet of the discharge water pipe, it is inconvenient to assemble and there is a problem of water leakage due to the lack of waterproofing in the binding part. Convex lens surface is exposed Standing sexual pinch and were uncomfortable to sit dust must manually wipe them during the inspection.

본 발명은 상기와 같은 불편을 해소하기 위하여 개발한 것이다.The present invention has been developed to solve the above inconvenience.

본 발명은 수도계량기의 보호통 내부로 지하 침출수가 유입되는 것을 막고 급수 수도관과 배출수도관 사이에 장치되는 수도계량기의 조립과 해체를 위해 급수수도관의 상단 개폐밸브 출구와 배출수도관의 상단 엘보 입구에 연결나사관을 신설하여 연결나사관이 결합시킨 체결나사를 통해 결속시키도록 하여 조립과 해체가 편리하게 하고 수도계량기의 검침이 편리하도록 볼록렌즈 상면에 청소구를 장치한 것이다.The present invention is connected to the upper opening and closing valve outlet of the water supply pipe and the upper elbow inlet of the discharge water pipe to prevent the infiltration of underground leachate into the protection tank of the water meter and to assemble and dismantle the water meter installed between the water supply pipe and the discharge water pipe. A new pipe is installed so that the connection screw can be connected through a fastening screw coupled to it, and a cleaning tool is installed on the upper surface of the convex lens to facilitate assembly and disassembly and to read the water meter.

이와 같이 된 본 발명은 수도 계량기 보호통의 바닥에 급수수도관과 배출수도관을 장치하기 위해 형성시킨 급수측안내관(1b)과 배수측안내관(1c)의 입구측에 고무패킹을 장치하고 내측에 그리스를 충진하였기 때문에 보호통 외측에서 내측쪽으로 침출수가 유입되는 것을 적극 차단하여 보호통 내부에 물이 들어오는 것을 방지하고 되고, 급수수도관과 배출수도관 사이에 수도계량기를 설치할 때 급수수도관의 상단 개폐밸브와 배출수도관의 상단 엘보 입구에 결합되도록 연결 나사관을 개입시키고 연결나사관의 환상돌출테에 체결나사를 결합시켜서 수도계량기의 입수구와 출수구측에 체결나사(13)(13a)를 나사 조립하기 때문에 연결나사관을 급수수도관(2)의 상단 개폐밸브(8), 출구(8b)와 배출수도관(2a)의 엘보(90) 입구 암나사에 먼저 나사조립하고, 체결나사(13)(13a)의 암나사를 수도계량기(12) 입수구와 출수구에 나사 조립하므로 조립과 해체가 간편하게 되는 이점이 있고,
특히 연결나사관은 환상돌출테가 형성된 통공 입구를 다각형 구멍(11b)으로 형성하여 수동렌치 결합이 용이하므로 암나사에 결합시킬 때 작업이 편리하게 되는 이점이 있고, 수도계량기 입수구와 출수구와 연결나사관의 접촉면에 누수방지패킹(14)이 개입되므로 누수염려가 없는 장점을 가지게 되며, 배출수도관(2a)과 엘보(90) 출구 사이에 역지밸브(9)가 장치되어 역류가 방지되고, 수도 계량기 검침부에 장치된 볼록렌즈 상면에 렌즈청소구(19)가 부착되어 있어서 평소 볼록렌즈 상면을 은폐하므로 성애가 끼이는 것을 막고 먼지가 앉는 것을 막아 청결을 유지하게 되어 검침시 편리하게 볼록렌즈를 사용할 수 있는 이점이 있다.In the present invention, the rubber packing is provided on the inlet side of the water supply side guide pipe 1b and the drainage side guide pipe 1c formed to install the water supply pipe and the discharge water pipe at the bottom of the water meter protection container. It prevents water from entering inside the protection container by actively blocking the inflow of leachate from the outside of the protection container to the inside, and when installing the water meter between the water supply pipe and the discharge water pipe, The coupling screw tube is screwed into the inlet and outlet of the water meter by interlocking the connecting screw tube to be connected to the upper elbow inlet and coupling the screw to the annular protrusion of the connecting screw tube. First, screw the upper opening / closing valve (8) of the water supply water pipe (2), the outlet (8b) and the inlet female thread of the elbow (90) of the discharge water pipe (2a), and fasten them. Since the female threads of the screws 13 and 13a are screwed into the inlet and outlet of the water meter 12, there is an advantage that the assembly and disassembly are simplified.
In particular, the connection screw tube is formed by the through hole inlet formed in the polygonal hole (11b) to facilitate the manual wrench coupling, there is an advantage that the work is convenient when combined with the female screw, water meter inlet and outlet port and connection screw pipe Leakage prevention packing (14) is introduced into the contact surface of the has the advantage that there is no risk of leakage, check valve (9) is installed between the discharge water pipe (2a) and the elbow 90 outlet to prevent backflow, water meter reading Since the lens cleaning port 19 is attached to the upper surface of the convex lens installed on the part, it normally conceals the upper surface of the convex lens, thereby preventing sexual intercourse and keeping dust clean so that the convex lens can be conveniently used during meter reading. There is an advantage to that.
