본 고안은 첵크밸브에 관한 것으로 특히, 첵크밸브에 설치되어서 관로상의 우체를 단속하는 첵크밸브용 변체의 구조에 관한 것이다.The present invention relates to a shank valve, and more particularly, to a structure of a shank valve for displacing the right body on the pipeline to be installed on the shank valve.
일반적으로 첵크밸브의 내부에 설치되어서 관로상의 유체를 단속하는 변체의 구조는 자동작동스프링에 의해 탄력지지되어 있고, 적어도 하나이상의 금속제 변체로 되어 있다.In general, the structure of the deformable body which is installed inside the check valve to control the fluid in the pipeline is elastically supported by an automatic operating spring, and is made of at least one metal deformable body.
이와같은 변체를 갖는 첵크밸브들은 밸브구조가 복잡하고, 고장수리가 용이하지 못하며, 중량이 많이 나가는 등의 단점과 유지비 및 시공비가 엄청나게 들어가는 단점이 있다.Shank valves having such a deformation have disadvantages such as a complicated valve structure, inability to easily troubleshoot, a heavy weight, and a huge maintenance cost and construction cost.
따라서 본 고안의 목적은 사기한 바와 같은 결함을 해결하기 위하여 개발된 것으로, 본 고안의 첵크밸브용 변체는 천연고무 재질이므로 소형. 경량이고, 내식, 내마모성이 우수하며, 워터함마등의 충격방지와, 힌지부의 마모를 극소화 시킬 수 있는 첵크밸브용 변체를 제공하는데 있다.Therefore, the purpose of the present invention was developed in order to solve the defects as fraudulent, the check valve for the check valve of the present invention is small because it is a natural rubber material. It is lightweight, excellent in corrosion resistance and abrasion resistance, to provide shock valves for shock valves and to minimize the wear of hinge parts.
본 고안의 다른 목적은 변체상에 상부로 연설되는 힌지부와, 상기 힌지구멍과, 그리고 변체상에 적어도 한쌍의 길이방향으로된 절결홈들의 구조를 포함하는 형태의 첵크밸브용 변체를 제공하는데 있다.Another object of the present invention is to provide a variant for a shank valve of the type including a hinge portion which is swept upwards on a deformable body, the hinge hole, and a structure of at least one pair of longitudinal cutouts on the deformable body. .
이하 본 고안의 구성 및 작용효과는 첨부한 도면을 참고로 양호한 실시예를 상술하면 다음과 같다.Hereinafter, the configuration and operation effects of the present invention will be described in detail with reference to the accompanying drawings.
부호 1은 밸브본체를 표시하며, 이 밸브본체(1)의 내부에 변체(2)가 설치 구성되어 있다.Reference numeral 1 denotes a valve body, and a valve body 2 is provided inside the valve body 1.
본 고안의 양호한 실시예에 의한 변체(2)는 천연고무 재질로 되어 있다.Variation 2 according to a preferred embodiment of the present invention is made of a natural rubber material.
이 변체(2)는 관로상 유체의 개방면 반대측에 적어도 한쌍의 길이방향으로된 절결홈(3a, 3b)들을 구비하고 있다.The deformable body 2 has at least one pair of longitudinal cutouts 3a and 3b opposite the open face of the fluid on the line.
그리고, 상기 변체(2) 상부로는 이 변체와 일체로 연설된 힌지부(4)와, 이 힌지부(4)의 상부중앙에 힌지구멍(5)을 천공하였다.In the upper part of the deformable body 2, the hinge part 4 integrally addressed with the deformed body and the hinge hole 5 in the upper center of the hinge part 4 were drilled.
상술한 변체(2)는 통상적인 힌지핀(6)으로 힌지구멍(5)을 통하여 밸브본체(1)에 고정설치되어 있다.The above-mentioned deformable body 2 is fixed to the valve body 1 through the hinge hole 5 by the normal hinge pin 6.
이와같이 구성된 본 고안의 첵크밸브용 변체(2)는 관로상에 설치된 상태에서 유체압에 의해 유체가 통과할시에는 제 1 도의 화살표 방향으로 변체(2)가 젖혀짐과 동시에 변체(2)상에 형성된 절결홈(3a, 3b)에 의하여 변체는 둥그스럼하게 관로상의 둥근면과 비슷하게 되면서 유체의 흐름을 더 한층 용이하게 한다.The shank valve body 2 according to the present invention configured as described above has the body 2 turned over in the direction of the arrow in FIG. By the notch grooves 3a and 3b formed, the deformed body becomes round and similar to the rounded surface on the conduit while further facilitating the flow of the fluid.
그리고, 유수의 압력이 정지되는 순간에는 천연고무 재질의 변체(2)는 밸브본체(1)의 밸브시이트에 긴밀히 밀착되면서 밸브체스트를 형성하며 관로상 유체를 완벽하게 차단시킬 수 있다.Then, at the moment when the pressure of the flowing water is stopped, the deformed body 2 of natural rubber material is in close contact with the valve seat of the valve body 1 to form a valve chest and completely block the fluid on the pipeline.
그러므로 본 고안의 첵크밸브용 변체는 상기와 같은 작동에 의하여 변체의 과다젖혀짐이 방지되고, 변체와 밸브시이트 사이의 유체의 누수를 방지할 수 있는 탁월한 성능을 가지고 있다.Therefore, the check valve body of the present invention has an excellent performance of preventing the over-wetting of the body by the operation as described above, and prevent the leakage of fluid between the body and the valve seat.
