Description

수도미터기의 역류방지구조{Water gauge for flowing backward prevention}Water gauge for flowing backward prevention

본 고안은 수도미터기에 구비된 출수부를 수도미터기 동체와 일체로 된 체결부와, 상기 체결부에 조립되는 출수관으로 분할 구성하고, 상기 체결부 내측에 역류방지밸브를 매우 신속 간편하면서도 안정적으로 조립 시공할 수 있게 하며, 확실한 역류방지로 인해 수도미터기의 오동작을 예방하여 신뢰성이 극대화될 수 있게 한 수도미터기의 역류방지구조에 관한 것이다.The present invention divides the water discharge part provided in the water meter into a fastening part integrated with the water meter body, and a water discharge pipe assembled to the fastening part, and assembles a non-return valve inside the fastening part very quickly and simply and stably. The present invention relates to a backflow prevention structure of a water meter which enables construction and maximizes reliability by preventing malfunction of the water meter due to reliable backflow prevention.

일반적으로 용수(수돗물)를 공급받아 사용하고 있는 각 가정이나 공장을 비롯한 여러 건물에는 용수의 흐름을 계측하여 사용량을 체크 할 수 있도록 수도미터기가 설치되어 있다.In general, water meters are installed in various buildings, such as homes and factories, where water is supplied and used to measure the flow of water.

이러한 종래의 수도미터기(100)는 첨부된 도1과 도2에서 도시된 바와 같이, 수돗물은 외갑체(1)에 형성된 급수관(1a)을 통해 그 내부에 설치된 계량기 유닛(2)의 하부내갑(2-2)을 통과하면서 수력으로 내부에 설치된 익차를 회전시키고, 이때 익차(2-3)의 회전수가 계량기 유닛(2)에 전달되어 검측이 이루어지게 되면서 외갑체(1)의 출수관(1b)을 거쳐 사용처로 공급되게 된다.As shown in FIG. 1 and FIG. 2 attached to the conventional water meter 100, the tap water has a lower inner shell (of the meter unit 2 installed therein through a water supply pipe 1 a formed in the outer shell body 1). 2-2) while rotating the vane installed therein by hydraulic power, and at this time the number of revolutions of the vane (2-3) is transmitted to the meter unit (2) to detect the water discharge pipe (1b) of the outer shell body (1) It is supplied to the place of use through).

또한, 상기 외갑체(1)의 배출관(1b)에는 역류방지밸브(3)를 설치하기 위해 설치관부(1-1)와 함께 마개(1-2)가 설치되며, 내부에는 축수부(1-3)가 형성되고, 이 축수부(1-3)는 외측으로부터 연장 형성되는 나사체결부(1-4)를 통해 힌지핀(P)의 삽입과 그 외측에서 힌지핀(P)의 이탈을 방지하는 고정 보울트(4)가 체결 설치된다.In addition, a stopper 1-2 is installed in the discharge pipe 1b of the outer shell body 1 together with the installation pipe part 1-1 to install the non-return valve 3. 3) is formed, and the bearing portion 1-3 prevents the insertion of the hinge pin P and the detachment of the hinge pin P from the outside through the screw fastening portion 1-4 extending from the outside. The fixing bolt 4 is fastened and installed.

상기 역류방지밸브(3)는 힌지부(3-1)가 축수부(1-3)에 연결되어 힌지핀(P)에 의해 회동가능하게 설치되고, 상기 힌지부(3-1) 하부에는 밸브시트(1-5)를 차단할 수 있는 원형의 밸브판체(3-2)가 형성되며, 밸브판체(3-2)의 내측에는 너트(5)와 고정나사(6)로서 역류시 밀폐효과를 높이도록 고무판(3-3)이 설치된 구성으로 이루어진다.The non-return valve 3 has a hinge portion 3-1 connected to the bearing portion 1-3 so as to be rotatable by a hinge pin P, and a valve below the hinge portion 3-1. A circular valve plate body 3-2 is formed to block the seat 1-5, and the inside of the valve plate body 3-2 has a nut 5 and a set screw 6 to increase the sealing effect during the back flow. Rubber plate 3-3 is installed.

위와 같이 구성된 종래 수도미터기의 역류방지구조는, 출수관에 설치된 역류방지밸브가 앵글밸브의 차단과 동시에 공급되던 물이 순간적으로 계량기 유닛으로 역류하는 것을 방지함으로서 수도미터기의 오동작을 예방하게 됨으로 항상 정확한 계측이 이루어지게 하기 위한 목적으로 개발 및 사용되고 있으나, 수도미터기에 역류방지 밸브가 조립되게 하는 구성은 이루 말할 수 없이 복잡하다.The reverse flow prevention structure of the conventional water meter configured as described above always prevents the malfunction of the water meter by preventing the water flow back to the meter unit at the same time as the check valve installed in the outlet pipe is blocked at the same time as the angle valve is blocked. Although it has been developed and used for the purpose of making the measurement, the configuration for assembling the non-return valve in the water meter is incredibly complex.

즉, 수도미터기에 역류방지를 위한 구성을 갖추기 위해서는 출수관(1b)에 수직으로 설치관부(1-1)와 마개(1-2)를 구비하여야만 하고, 상기 설치관부(1-1)를 통해 역류방지밸브(3)를 삽입시킨 상태에서 축수부(1-3) 사이에 힌지부(3-1)를 위치시킨 뒤 외부에서 나사체결부(1-4)의 구멍을 통해 힌지핀(P)을 삽입하며, 이어서 상기 힌지핀(P)이 분해되지 않도록 보울트(4)를 체결한 다음 설치관부(1-1) 상부에 마개(1-2)를 조립하여야만 함으로서 부품수가 많아 제조에 따른 금형비를 비롯한 제반 경비가 많이 들고, 또 조립이 매우 번거롭고 손이 많이 가는 구성이기에 생산성이 크게 떨어지면서도 인력이 많이 드는 등 많은 폐단이 따랐다는 것이다.That is, in order to equip the water meter to prevent backflow, the installation pipe part 1-1 and the stopper 1-2 should be provided perpendicularly to the water outlet pipe 1b, and through the installation pipe part 1-1. Place the hinge part 3-1 between the bearing parts 1-3 while the check valve 3 is inserted, and then hinge pin P through the hole of the screwing part 1-4 from the outside. Insert the next, and then fasten the bolt (4) so that the hinge pin (P) is not disassembled, and then the stopper (1-2) must be assembled on the upper part of the installation pipe (1-1) to increase the mold cost according to the number of parts In addition, the cost is high, and the assembly is very cumbersome and requires a lot of hands.

본 고안은 전술한 종래의 제반문제점을 감안하여 안출된 것으로서, 특히 수도미터기의 출수부를 분리 구성하여 수도미터기 동체와 일체로 된 체결부와 상기 체결부에 분해 조립되는 출수관으로 분리하여 분해 조립이 용이하도록 구성하되, 상기 체결부 내에 밀폐부재와 함께 역류방지용 밸브를 장착함에 있어서 별도의 체결부재 없이 손쉽게 삽입 장착할 수 있게 함으로서 조립이 매우 신속 간편하게 이루어지는 수도미터기의 역류방지구조를 제공하려는데 그 목적이 있는 것이다.The present invention has been devised in view of the above-mentioned conventional problems, and in particular, the water outlet part of the water meter is configured to be separated and separated into a fastening part integrated with the water meter body and a water outlet pipe that is disassembled and assembled. Although it is configured to facilitate, in order to easily install and insert without a separate fastening member in mounting the check valve with the sealing member in the fastening portion to provide a backflow prevention structure of the water meter is very quick and easy assembly. It is.

또한, 상기 역류방지밸브의 구성을 지극히 간단하게 함으로서 조립성 및 신뢰성을 극대화시킬 수 있게 하려는 데도 그 목적이 있는 것이다.In addition, the purpose is to make the configuration of the non-return valve extremely simple to maximize the assembly and reliability.
