이하 본 고안을 첨부도면의 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안의 설치도이고1 is an installation diagram of the present invention
도 2는 본 고안의 단면도로서2 is a cross-sectional view of the present invention
도 1 내지 도 2에 도시된 바와 같이As shown in FIGS. 1 to 2
중공지주(13)를 통하여 수도계량기 보호통(12)의 내부로 설치한 입수관(14)과 출수관(15)의 단부에는 볼밸브(1)와 엘보(16)를 고정하여 수도계량기(17)를 설치하여서 된 것에 있어서The ball valve 1 and the elbow 16 are fixed to the ends of the water inlet pipe 14 and the water outlet pipe 15 installed into the water meter protection tube 12 through the hollow column 13 to supply the water meter 17. In that by installing
밸브보디(2)의 입수구(2A)와 출수구(2B) 사이에 테프론패킹(3)에 의하여 수밀되게 설치한 볼(4)을 작동시키기 위한 밸브봉(5)은 밸브보디(2)의 세로방향의 측면에 설치하고 The valve rod 5 for operating the ball 4 which is tightly installed by the Teflon packing 3 between the inlet port 2A and the outlet port 2B of the valve body 2 is the longitudinal direction of the valve body 2. On the side of the
밸브보디(2)의 상부는 개방하여 마개(6)로 밀폐시킬 수 있도록 하되 밸브보디(2)의 내부에는 여러 개의 반원홈(8A)을 형성한 고무변판(8)의 양측에 금속보강판(9)을 볼트(10) 및 너트(11)로 고정한 역류방지변(7)을 상하이동 자유롭게 삽입한 것을 특징으로 한 것이다.The upper part of the valve body 2 can be opened and sealed with a stopper 6, but metal reinforcing plates (2) are formed on both sides of the rubber side plate (8) having a plurality of semicircular grooves (8A) formed inside the valve body (2). It is characterized in that the non-return valve 7 fixed with the bolt 10 and the nut 11 is freely inserted into the shanghai.
미설명부호 5A는 볼트가 끼워지는 홈 이고Reference numeral 5A is a groove to which the bolt is fitted.
18은 볼트 이다.18 is the volt.
이와 같이 된 본 고안은 기존의 수도계량기 보호통(12) 내부의 입수관(14)에는 밸브보디(2)의 입수구(2A)를 고정하고 출수구(2B)는 수도계량기(17)와 연결하여 볼밸브(1)를 항상 열어놓은 상태에서 사용하게 되고 상수도의 물은 입수관(14) 측에서 출수관(15) 측으로 흐르게 되는 것으로서 상기에 있어서 상수도의 물이 입수관(14)에서 출수관(15)으로 흐를 때는 수압에 의하여 역류방지변(7)은 도 2에 도시된 바와 같이 상승된 상태로 유지케 되는데 이때 고무변판(8)에는 수개의 반원홈(8A)이 형성되었으므로 수압을 받는 면적이 반원홈(8A)만큼 감소됨과 아울러 또한 고무변판(8)은 쿠션이 좋은 고무제로 되었으므로 수압의 강약에 양호하게 적응케되어 마개(6)에 부딪치는 노킹형상으로 인한 충격을 완화시킬 수 있다.The present invention thus obtained is fixed to the water inlet (2A) of the valve body (2) to the water inlet pipe 14 in the existing water meter protection tank 12, the outlet (2B) is connected to the water meter (17) ball valve (1) is to be used in the open state at all times, the water of tap water flows from the inlet pipe 14 side to the outlet pipe 15 side, the water of the tap water in the inlet pipe 14 to the outlet pipe 15 When it flows into the backflow preventing valve 7 is maintained in an elevated state by the water pressure as shown in Fig. 2 at this time, the rubber side plate 8 is formed with a number of semi-circular grooves (8A), the area subjected to hydraulic pressure is semicircle In addition to being reduced by the groove 8A, the rubber stool 8 is made of a rubber having a good cushion, so that the rubber stool 8 is well adapted to the pressure of the hydraulic pressure, thereby alleviating the impact due to the knocking shape that strikes the stopper 6.
이에 따라 역류방지변(7)의 손상방지로 사용수명을 오래 유지시킬 수 있다. 상기의 작동상에 있어서 무단으로 단수상태로 되거나 입수관(14) 측의 수도관의 교체작업으로 볼밸브(1)에 수압이 가해지지 않을 시에는 역류방지변(7)이 하강되어 도 2의 가상선표시와 같이 하강상태로 유지됨으로 출수관(15) 측에서 점선화살표방향으로 이동되는 역류는 차단된다. Accordingly, it is possible to maintain a long service life by preventing damage to the non-return valve (7). In the above operation, when the water is not cut off steplessly or when water pressure is not applied to the ball valve 1 due to the replacement of the water pipe on the inlet pipe 14 side, the non-return valve 7 is lowered and the virtual of FIG. As it is maintained in the down state as shown by the line display, the backflow moving in the direction of the dotted line arrow on the outlet pipe 15 side is blocked.
그리고 본 고안은 요지를 벗어나지 않는 범위 내에서 변화시킬 수 있다. And the present invention can be changed within the scope without departing from the gist.
이와 같은 본 고안은 밸브봉(5)은 측면에 설치하고 상부는 마개(6)로 개폐시킬 수 있는 개구부를 형성하여 밸브보디(2)의 내부에 상하이동 자유롭게 역류방지변(7)을 내입하였으므로 역류를 방지할 수 있고 역류방지변(7)의 고무변판(8)은 고무로 형성하고 외면에는 여러 개의 반원홈(8A)을 형성하여 수압의 강약에 적응되도록 하였으므로 쉽게 손상되지 않아 사용수명을 오래 유지시킬 수 있는 효과가 있다.The present invention is such that the valve rod (5) is installed on the side and the upper portion forms an opening that can be opened and closed with a stopper (6), so that the free flow prevention valve (7) inside the valve body (2) Backflow can be prevented and the rubber side plate (8) of the backflow prevention side (7) is made of rubber and formed on the outer surface with several semicircular grooves (8A) to be adapted to the strength of the hydraulic pressure, so it is not easily damaged and thus the service life is long. There is an effect that can be maintained.
