상기 작동부(120)는 지지블록(112)의 가이드홈(113)에 하부에 플랜지(125)를 형성한 밀폐구(123)를 삽입하여 고정하되 플랜지(125)를 고정클립(116)으로 고정하도록 한다.The operating part 120 is fixed to the guide block 113 of the support block 112 by inserting a sealing hole 123 having a flange 125 at the bottom thereof and fixing the flange 125 to the fixing clip 116 .

여기서 밀폐구(123)는 수직으로 확장공(124)을 수직으로 형성하여 작동관(121)을 관통시킬 수 있도록 함과 동시에 고무 등의 탄성재질로 형성하여 원활하게 수축 팽창할 수 있도록 함이 바람직하다.In this case, it is preferable that the closing hole 123 is vertically formed so as to vertically extend through the operating pipe 121, and is formed of an elastic material such as rubber so as to be smoothly expanded and contracted Do.

특히 작동관(121)은 지지블록(112)의 결합관(112a)와 밀폐구(123)의 확장공(124)을 관통시켜 형성하되 작동관(121)의 상단 외주연에 작동구(122)를 형성하여 작동관(121)의 하강으로 작동구(122)가 밀폐구(123)의 확장공(124)에 끼워지면서 밀폐구(123)의 외경을 확장시킬 수 있도록 한다.Particularly, the operation pipe 121 is formed by penetrating the coupling pipe 112a of the support block 112 and the expansion hole 124 of the closing hole 123, and the operation hole 122 is formed on the outer periphery of the upper end of the operation pipe 121, So that the operating hole 122 of the operating pipe 121 is inserted into the opening hole 124 of the closing hole 123 and the outer diameter of the closing hole 123 can be enlarged.

따라서 밀폐구(123)는 확장 전에 가스미터(1)의 유입구(10)와 배출구(20)에 삽입할 수 있도록 하고 확장 후에 유입구(10)와 배출구(20)의 내주연에 밀착하여 가스미터(1)를 밀폐시켜 작동관(121)으로 점검 가스를 통과시키도록 함이 바람직하다.The sealing member 123 can be inserted into the inlet 10 and the outlet 20 of the gas meter 1 before expansion and is closely contacted with the inner periphery of the inlet 10 and the outlet 20 after expansion, 1) is sealed so that the check gas is passed through the operation pipe 121.

나아가, 작동구(122)의 하부 외주연에 테이퍼(122a)을 형성하여 밀폐구(123)의 확장공(124)에 원활하게 삽입할 수 있도록 하고 작동관(121)의 하단에 가스를 공급 배출하는 호스를 용이하게 결합하는 연결부(121a)를 형성한다.Further, a taper 122a may be formed at the lower outer periphery of the operation port 122 to smoothly insert into the expansion hole 124 of the closing port 123, and a gas may be supplied to and discharged from the lower end of the operation pipe 121 Thereby forming a connection portion 121a for easily coupling the hose.

상기 동력전달부(130)는 안치플레이트(111)의 저면에 실린더(131)를 구비하고 실린더(131)의 로드에 승하강바(132)를 수평으로 결합하며 승하강바(132)의 좌우 양단에 작동바(134)을 연결구(133)로 결합하되 작동바(134)를 작동관(121)에 결합하므로, 실린더(131)의 제어로 승하강바(132)가 승하강하면 작동관(121)도 연동하여 승하강 할 수 있도록 한다.The power transmission unit 130 includes a cylinder 131 on the bottom surface of the seat plate 111 and horizontally couples the lifting bar 132 to the rod of the cylinder 131, When the lifting and lowering bar 132 is lifted and lowered under the control of the cylinder 131 by connecting the operating bar 134 to the operating pipe 121 by connecting the operating bar 134 to the operating pipe 121, So that it can be moved up and down.

한편, 상기 식별부(140)는 압력게이지(141)를 구비하여 세워 설치하되 압력게이지(141)에 압력통로(142)를 수직으로 형성하고 압력통로(142)에 무게추(143)를 결합하여 압력의크기에 따라 승하강할 수 있도록 하며 압력통로(142)의 측방으로 표시눈금(143)을 형성하도록 한다.The identification unit 140 includes a pressure gauge 141 and a pressure gauge 141. The pressure gauge 141 is vertically formed with the pressure gauge 141 and the weight 143 is coupled to the pressure passage 142 The display scale 143 is formed on the side of the pressure passage 142 so that the display scale 143 can be raised and lowered according to the magnitude of the pressure.

여기서 압력게이지(141)의 압력통로(142)는 작동관(121)에 연결하여 검사 가스를 공급 또는 배출하는 가스관에 연통시킨다
즉, 검사 가스의 입력측 또는 배출측에 연통시켜 가스미터(10)에 인가하는 압력을 육안으로 손쉽게 식별할 수 있도록 한다.Here, the pressure passage 142 of the pressure gauge 141 is connected to the working pipe 121 to communicate with a gas pipe for supplying or discharging the inspection gas
That is, the pressure applied to the gas meter 10 is communicated to the input side or the discharge side of the inspection gas so that the pressure applied to the gas meter 10 can be visually recognized easily.

이러한 본 발명의 작용을 설명하면 다음과 같다.The operation of the present invention will be described as follows.

먼저, 안치플레이트(111)에 형성한 지지블록(112)의 가이드홈(113)에 가스미터(1)의 유입구(10)와 배출구(20)를 삽입하면 유입구(10)와 배출구(20)의 내부로 밀폐구(123)가 삽입된다.When the inlet 10 and the outlet 20 of the gas meter 1 are inserted into the guide groove 113 of the support block 112 formed on the mounting plate 111, And a hermetic seal 123 is inserted into the inside thereof.

이러한 상태에서 실린더(131)를 제어하여 승하강바(132)를 하강시키면 승하강바(132)에 연결시킨 작동관(121)도 연동하여 하강하게 되고 이로 인하여 작동관(121)의 상단 외주연에 형성시킨 작동구(122)가 하강하여 밀폐구(123)의 확장공(124)으로 압입된다.When the lifting bar 132 is lowered by controlling the cylinder 131 in this state, the working tube 121 connected to the lifting bar 132 is also lowered in cooperation with the upper end of the working pipe 121, The operation member 122 formed on the support member 123 is lowered and press-fitted into the expansion hole 124 of the closing member 123. [

따라서 밀폐구(123)의 확장공(124)이 팽창하여 확장하게 되고 이로 인하여 밀폐구(123)의 외경이 팽창하여 확장하므로 유입구(10)와 배출구(20)의 내주연을 밀폐시키는 것이다.Accordingly, the expansion hole 124 of the hermetic seal 123 expands and expands, thereby expanding and expanding the outer diameter of the hermetic seal 123, thereby sealing the inner periphery of the inlet 10 and the discharge opening 20.

가스미터(1)의 유입구(10)와 배출구(20)의 결합 및 밀폐가 완료되면 검사 가스를 정적압력으로 주입하여 가스의 누출 여부를 확인한다.When the connection between the inlet 10 and the outlet 20 of the gas meter 1 is completed and the sealing is completed, the test gas is injected at a static pressure to check whether the gas leaks.

여기서 누출 검사 가스를 주입하면 가스미터(1)와 식별부(140)가 가스관으로 연통된 상태이므로 동일한 압력을 상태를 유지한다.
즉 압력게이지(141)의 무게추(143)는 인가되는 압력에 의해 압력통로(142)를 따라 상승하게 되고 이때 적정 압력까지 도달하며 가스 주입을 중단한다.
따라서 가스미터(1)에서 가스누출이 발생하면 인가 압력이 떨어지므로 일정시간 동안 무게추(143)가 허용 범위 이내로 떨어짐을 살펴 가스누출 유무를 확인할 수 있도록 한다.Here, when the leakage inspection gas is injected, the gas meter 1 and the identification unit 140 are in a state of being communicated with the gas pipe, so that the same pressure is maintained.
That is, the weight 143 of the pressure gauge 141 is raised along the pressure passage 142 by the applied pressure, and reaches the proper pressure to stop the gas injection.
Therefore, when the gas leakage occurs in the gas meter 1, the applied pressure drops, so that the weight 143 falls within the allowable range for a predetermined period of time, so that the presence of gas leakage can be checked.
