Abstract

PURPOSE: A sliver is further provided to a ball valve to prevent stress of an O-ring by a rotation friction of a stem. CONSTITUTION: A sliver(1) is formed between an inside of a valve and an O-ring(2) of a stem(3). The sliver works as a bushing to absorb rotation friction. The sliver is not limited with a rotation direction to prevent stress to the O-ring by a rotation friction of the stem. The stem and sliver is assembled, disassembled and replaced by a vertical pipe portion(4). A stop ring(9) is provided to prevent escaping of the sliver.

Description

장수 볼밸브{Longevity ball Valve}Longevity ball valve

종래 볼 밸브는 스템(3)의 오링(2)이 스템(3)의 회전마찰로 인해 마모되어 누수가 발생하므로,는 관계로 밸브 전체를 교체해야 하는 경우이거나 스템(3)을 밸브 상단에서 분리토록 하여 오링(2)이 마모시에 오링(2)을 교환 하여 부분 수리가 가능 하도록 하고 있으나 근본적으로 오링(2)의 마모를 줄일 수 있는 구조의 밸브는 아니었다. 오링(2)의 마모로 인하여 교체되는 오링(2)의 부품의 비용 보다 오히려 교체시에 발생되는 인건비가 상당히 소요 되는바 경제성 또한 문제로 지적 되기 때문에 근본적인 문제 해결은 오랜 기간 누수가 되지 않도록 오링(2)의 수명을 연장시키는데 있다.Conventional ball valves have leaks due to wear of the O-rings 2 of the stem 3 due to rotational friction of the stem 3, so that the entire valve must be replaced or the stem 3 can be removed from the top of the valve. Thus, the O-ring (2) to replace the O-ring (2) when worn out to allow partial repair, but it was not essentially a valve structure that can reduce the wear of the O-ring (2). Rather than the cost of parts of the O-ring (2) to be replaced due to the wear of the O-ring (2), the labor cost incurred during the replacement is considerably expensive, and economical is also pointed out as a problem, so the fundamental problem solving is to prevent the leakage of the O-ring ( 2) to extend the life.

볼 밸브에서 스템(3)이 회전 하면서 밸브 내면과 스템(3)의 오링(2)이 상당한 회전 마찰력 가지고 있으며 이로 인하여 오링(2)의 수명이 단축 되기 때문에 오링(2)의 수명을 극대화 시키고,필요시 부분 교환이 가능 하여야 하는데,본 발명은 스템(3)의 오링(2)과 밸브 내면사이에 구성되어 회전 마찰을 흡수할 수 있는 슬리버(1)를 새롭게 사용하여 슬리브(1)가 부시 역할을 하여 근본적인 오링(2)에 작용되는 마찰력을 최소화 시켰고 스템(3)의 회전마찰로 인해 발생되는 오링(2)의 특정 부위에 직접 작용되는 스트레스를 방지하기 위하여 슬리버(1)를 회전 방향으로 구속 하지 않도록 유동성을 가지는 구조로 제작하여 오링(2)의 수명을 종전에 비해 대폭적으로 연장 하였다. 또한 스템(3)과 슬리버(1)를 밸브 상단으로 개방시킨 수직관부(4)를 통해서 조립,분해,필요시 교환 가능 하도록 하였고 슬리브의 이탈을 방지 하는 멈춤링(9)으로 최종 결합하는 구조로 고안한다.As the stem (3) rotates in the ball valve, the O-ring (2) of the valve inner surface and the stem (3) has a considerable rotational friction force, which minimizes the life of the O-ring (2), thereby maximizing the life of the O-ring (2), Partial exchange should be possible if necessary. In the present invention, the sleeve 1 acts as a bush by newly using a sliver 1 configured between the O-ring 2 of the stem 3 and the valve inner surface to absorb rotational friction. This minimizes the frictional force acting on the underlying O-ring (2) and restrains the sliver (1) in the rotational direction in order to prevent stress acting directly on a specific part of the O-ring (2) generated by the rotational friction of the stem (3). In order not to make it has a fluid structure to extend the life of the O-ring (2) significantly than before. In addition, the stem (3) and the sliver (1) are assembled, disassembled, and exchanged if necessary through the vertical pipe part (4) opened to the upper end of the valve, and the structure is finally combined with a stop ring (9) that prevents the sleeve from detaching.

본 고안은 주로 냉온수 배관라인에 설치하는 볼 밸브의 제조기술에 관한 것으로 볼 밸브에서 스템(3)이 회전 하면서 밸브 내면과 스템(3)의 오링(2)이 상당한 마찰력 가지고 있으며 이로 인하여 오링(2)의 수명이 짧아 지며,필요시 부분 교환이 가능 하여야 하는데,본 발명은 스템(3)의 오링(2)과 밸브 내면사이에 구성되어 회전 마찰을 흡수할 수 있는 슬리버(1)를 새롭게 사용하여 슬리브()가 부시 역할을 하여 근본적인 오링(2)의 마모를 최소화 시켰고 스템(3)의 회전마찰로 인해 발생되는 오링(2)의 특정 부위에 작용되는 스트레스를 방지하기 위하여 슬리버(1)를 회전 방향으로 구속 하지 않도록 유동성을 가지는 구조로 제작하여 오링(2)의 수명을 종전에 비해 대폭적으로 연장 하였다. 또한 스템(3)과 슬리버(1)를 밸브 상단으로 개방시킨 수직관부(4)를 통해서 조립,분해,교환 가능 하도록 하였고 슬리브의 이탈을 방지 하는 멈춤링(9)으로 최종 결합하는 구조로 구성된다.The present invention mainly relates to a manufacturing technique of a ball valve installed in a cold / hot water pipe line. As the stem (3) rotates in the ball valve, the O-ring (2) of the valve inner surface and the stem (3) have a considerable friction force, and thus the O-ring (2) The life span of the crankshaft should be shortened and a partial exchange should be possible if necessary. The present invention uses a sliver (1), which is composed between the O-ring (2) of the stem (3) and the inner surface of the valve, to absorb rotational friction. The sleeve () acts as a bush to minimize the wear of the underlying o-ring (2) and to rotate the sliver (1) in order to prevent the stress acting on a particular part of the o-ring (2) caused by the rotational friction of the stem (3). The O-ring (2) has a long life compared to the previous one by making it have a fluid structure so as not to restrain the direction. In addition, the stem 3 and the sliver 1 can be assembled, disassembled, and exchanged through the vertical pipe part 4 that opens to the upper end of the valve, and the structure is finally combined with a stop ring 9 that prevents the sleeve from detaching. .

슬리버(1)를 새로이 적용 하여 종전 방식의 밸브 와 비교 테스트 및 사용 결과 회전시 발생되는 마찰력이 10배 이상 감소 하였고 오링이 마모되는 정도 또한 10배 이상 감소 되어 구동기를 부착 하여 밸브를 사용시에는 작은 전력이 소모되어 에너지 절감 효과 및 구동용 전동기를 작은 사이즈로 설계 가능 하므로 구동기 제작비가 줄어든다. 또한,회전시에 마찰력을 감소시켜 밸브 누수의 주범인 오링(2)의 수명을 극대화 시키고,또한 교체되는 부품의 비용 보다 오히려 교체시의 인건비가 상당히 소요 되는바 경제성 또한 문제로 지적 되기 때문에 근본적인 문제 해결은 오랜 기간 누수가 되지 않도록 오링(2)의 수명을 연장시켜 반 영구적으로 사용 하는데 있다. 그리고 필요시 슬리버(1)와 오링(2)을 교환하여 밸브를 영구적으로 사용가능 하도록 하였다.As a result of the new application of the sliver (1), as compared with the conventional valve, the frictional force generated during rotation has been reduced by more than 10 times, and the degree of wear of the O-ring is also reduced by more than 10 times. This reduces energy consumption and reduces the manufacturing cost of the driver because the motor can be designed in a small size. In addition, by reducing friction during rotation, the life of the O-ring (2), which is the main cause of valve leakage, is maximized, and the labor cost of replacement is considerably higher than the cost of replacement parts. The solution is to prolong the life of the O-ring (2) so that it does not leak for long periods of time, thus semi-permanently using it. If necessary, the sliver (1) and the O-ring (2) were exchanged to make the valve permanently usable.
