Description

양면 내압식 버터플라이 밸브{BUTTERFLY VALVE}Double-sided pressure butterfly valve {BUTTERFLY VALVE}

본 고안은 물, 유류, 가스, 공기등과 같은 각종유체가 흐르는 관로의 일정구간에 유체를 차단하는 양면 내압식 버터플라이 밸브에 관한것으로서, 특히 밸브 몸통의 내주면에 내장된 탄성체또는 금속제인 몸통시이트링을 고정시키는 특수형상의 시이트 고정링을 밸브 몸통 외부에 장착된 테이퍼 쐐기구조의 다수의 조절볼트를 조정하여 밸브가 폐쇄시 폐쇄된 밸브 디스크 양방향으로 작용하는 수압을 지수시키는 양면내압식 버터플라이 밸브에 관한 것이다.The present invention relates to a double-sided pressure-resistant butterfly valve that shuts off a fluid in a certain section of a pipeline through which various fluids such as water, oil, gas, and air flow. Double-sided pressure-resistant butterfly valve that regulates the water pressure acting in both directions of the valve disc closed when the valve is closed by adjusting a number of adjustment bolts of tapered wedge structure mounted on the outside of the valve body with special shape sheet fixing ring to fix the ring It is about.

종래에도 버터플라이 밸브가 제안 사용되어 왔으나, 일반적으로 원통상의 밸브 몸통 내주면에 밸브몸통시이트링을 고정하고, 밸브 몸통에 회전축으로 축설한 원판디스크의 외주면에는 탄성체 디스크 시이트링을 디스크 시이트 고정링 및 다수의 시이트링 고정볼트로 고정시킨 구조로 되어 있으며, 디스크를 회전시켜 밸브 몸통 시이트링에 디스크 시이트링을 접촉압착되게 되므로서 송수관을 폐쇄하게 된다. 그러나, 기존의 버터플라이 밸브는 밸브폐쇄시에 접촉면이 경사면인 몸통시이트링과 탄성체인 디스크 시이트링이 유체가 흐르는 방향으로 접촉압착력에 의하여 유체흐름의 작용 압력을 차단하도록 되어있어, 지수를 목적으로 무리하게 디스크 시이트링 고정볼트를 조임으로서 탄성체의 디스크 시이트링이 영구변형되어 탄성력 상실로 수명이 단축되어 지수가 어려울뿐만아니라, 무리한 조임으로 밸브 개패시 즉 디스크 이탈시 상당히 큰 동력이 소요될뿐만 아니라 역방향의 작용수압을, 밸브의 구조상 접촉면이 경사면의 반대방향의 작용수압인 관계로 지수가 거의 불가능하여, 이러한 결점을 보안코저 원판디스크를 양방향측 회전축을 중심으로 대칭으로 디스크를 설정하여 디스크 시이트링과 몸통시이트링의 양방향 즉 2개소로 설치하여, 각각 방향의 수압을 지수토록 하는 구조의 이중디스크형 버터플라이 밸브로 사용되어 왔으며, 아울러, 밸브가 송수관로등에 설치되어 누수가 발생시 밸브 몸통시이트링 및 디스크 시이트링 조정이 필요할시에는 밸브를 관로에서 절단또는 분리하여 조정하던지 또는 사람이 관로 내부로 들어가서 시이트 조정볼트를 조정하는등 유지관리가 용이하지 못할뿐만 아니라 경제적으로도 상당한 손실이 발생하였다.In the past, a butterfly valve has been proposed and used, but in general, a valve body seat ring is fixed to an inner circumferential surface of a cylindrical valve body, and an elastic disk seat ring is provided on an outer circumferential surface of a disc disk that is formed with a rotating shaft on the valve body. It has a structure fixed by a plurality of seat ring fixing bolts, and the disk seat ring is pressed against the valve body seat ring by rotating the disk to close the water pipe. However, in the conventional butterfly valve, when the valve is closed, the body seat ring with the inclined surface and the disc seat ring with the elastic body block the working pressure of the fluid flow by the contact pressure in the direction of the fluid flow. By tightening the disc seat ring fixing bolt excessively, the disc seat ring of the elastic body is permanently deformed and the life is shortened due to the loss of elastic force, and the index is difficult. Since the hydraulic pressure of the valve is almost impossible due to the contact surface of the valve in the opposite direction of the inclined surface, it is almost impossible to solve this problem. It is installed in both directions of body seat ring or two places, and each room It has been used as a double-disc butterfly valve with a structure that allows the water pressure to be reduced.In addition, when the valve is installed in a water supply line, it is necessary to adjust the valve body seat ring and the disc seat ring when water leakage occurs. It is not easy to maintain, such as adjusting the seat adjusting bolts or adjusting the seat adjusting bolts.

본고안의 목적은, 밸브몸통의 내주면에 내장된 탄성체 또는 금속제인 몸통시이트링을 고정하는 특수형상의 시이트 고정링을 밸브몸통 외부에 장착된 테이퍼 쐐기 구조의 다수조절볼트를 조절하여, 밸브에 작용하는 양방향 수압을 지수시키는 것을 특징으로 하는 양면내압식 버터플라이 밸브로서, 제작원가를 절감하고,효용성을 높이며,유지관리가 편리하고,기존이중디스크 버터플라이 밸브보다 콤팩트하고,유체저항도 적어,유체를 송수, 가압하는 구동펌프보다더 용량을 적게 할수있다.The purpose of this paper is to adjust the multiple adjustment bolts of tapered wedge structure mounted on the outside of the valve body by fixing a special seat fixing ring for fixing the body seat ring made of elastic body or metal on the inner circumferential surface of the valve body. It is a double-sided pressure resistant butterfly valve characterized by indexing water pressure in both directions, which reduces manufacturing cost, improves utility, and is easy to maintain, and is more compact than conventional double disc butterfly valves, and has less fluid resistance. The capacity can be lower than that of the driving pump to feed and pressurize.

본 고안에 따르면, 밸브본체(1)의 내주면에 내장된 탄성체 또는 금속제인 몸통시이트링(2)을 한면으로 고정시키는 환링형상의 시이트 고정링(3)을 착설하며, 시이트고정링(3)의 다른 일면은 테이퍼 구조의 쐐기 형상(4)으로, 밸브 몸통(1)의 외부에 원주 방향으로 균등하게 착설된 다수의 쐐기(4)형상을 갖는 조절볼트(5)를 나사부 결합으로 장착된 것을 특징으로 하는 양면 내압식 버터플라이 밸브가 제공된다.According to the present invention, a ring ring-shaped sheet fixing ring (3) for fixing the body sheet ring (2) made of an elastic body or metal embedded in the inner circumferential surface of the valve body (1) to one side, and the seat fixing ring (3) The other side is tapered wedge shape (4), characterized in that the adjustment bolt 5 having a plurality of wedges (4) shape evenly installed in the circumferential direction on the outside of the valve body (1) is mounted by screwing Double-sided pressure butterfly valve is provided.

이하, 본고안의 바람직한 실시예를 첨부한 도면에 의거 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

유체의 흐름을 차단하기 위해 밸브 디스크(6)를 폐쇄하고져 회전축(7)을 회전시켜 밸브 디스크(6)를 닫아주면, 디스크 시이트링(8)이, 밸브 몸통시이트링(2)의 정점에 서서히 압착되어 완전히 닫혔을 경우, 유체의 흐름을 정확히 차단하여 준다.In order to shut off the flow of the fluid, the valve disc 6 is closed, and the rotary shaft 7 is rotated to close the valve disc 6, so that the disc seat ring 8 slowly reaches the top of the valve body seat ring 2. When squeezed and completely closed, it blocks the flow of fluid correctly.

이때 디스크 시이트링(8)과 밸브 몸통시이트링(2)의 압착력을 균등하게 작용하도록 밸브 몸통(1)내주에 장착된 시이트 고정링(3)의 테이퍼 구조의 쐐기 형상의 경사접촉면(4' )과 여기에 대향하는 밸브 몸통(1)외부에 장착된 다수의 조절볼트의 쐐기형상(4)의 경사 접촉면(4' )이 밸브 몸통(1)의 중심에 대한 수직상하운동으로밸브몸통 시이트 고정링( 3 )이 밸브몸통(1)의 중심에 대안 수평방향으로 이동이 가능하므로서, 밸브몸통시이트(2)과 디스크 시이트링(8)의 균일한 압착력으로 양쪽시이트링 원주방향으로 완벽하게 지수가 이루어 지며, 압착정도도 조절나사(5)의 나사부 죄임 상태를 조정하므로서 용이하게 조정가능하며, 균일한 압착력으로 밸브개폐시 적은힘이 소요되므로, 원활한 작동이 이루어지며, 모터 전동구동등 외부동력사용시에도 적은 동력이 소요되며, 밸브 제작시 화살표 방향과 같이 밸브의 역방향 수압시험시의 누수발생에도 외부에서 조절볼트(5)의 조임으로 쉽게 지수를 조절할 수있으며, 또한 장시간 사용할 때 시이트링 부위의 마모등으로 누수가 발생할시에는 밸브가 설치된 기존 밸브를 관로에서 분해하지 않고, 관로외부즉 밸브 몸통(1)의 외부에 착설된 다수의 조절나사(5)의 나사부를 조정하므로서 쉽게 조정할수 있다.At this time, the wedge-shaped inclined contact surface 4 'of the tapered structure of the seat fixing ring 3 mounted on the inner circumference of the valve body 1 so that the pressing force between the disc seat ring 8 and the valve body seat ring 2 is equally applied. And the inclined contact surface (4 ') of the wedge shape (4) of the plurality of adjustment bolts mounted outside the valve body (1) facing the valve body in the vertical vertical movement with respect to the center of the valve body (1) (3) The center of the valve body (1) can be moved in an alternative horizontal direction, so that the uniform pressure of the valve body sheet (2) and the disc seat ring (8) is perfectly indexed in both seat ring circumferential directions. The degree of crimping can be easily adjusted by adjusting the tightening state of the screw part of the adjusting screw (5), and even less pressure is required when opening and closing the valve with a uniform crimping force, so that smooth operation is achieved and even when using external power such as motor electric drive. Less power When the valve is manufactured, the index can be easily adjusted by tightening the adjusting bolt (5) from the outside, even if leakage occurs during the reverse hydraulic test of the valve as shown by the arrow direction. When it occurs, it can be easily adjusted by adjusting the threads of the plurality of adjustment screws (5) installed on the outside of the pipeline, that is, the outside of the valve body (1) without disassembling the existing valve installed valve.

이상에서와 같이 본고안에 의하면, 밸브 몸통(1)의 내주면에 장착된 몸통시이트링(2)을 조절할 수 있는 조절볼트(5)를 밸브몸통(1)외부에 장착하므로서, 양방향의 유체흐름에 대한 누수를 완벽히 차단해 주며, 사용할 때 누수가 발생시에도 외부에서 쉽게 조정이 가능하므로, 반 영구적으로 사용할수 있으며, 이중 디스크 버터플라이 밸브 보다도 유체저항이 적어 코스트를 절감할수 있고, 관로의 유체를 송수, 가압하는 구동 펌프모터의 용량을 적게 할수있으며, 밸브의 사용유지보수가 펀리한 양면 내압식 버터플라이 밸브를 제공할수 있다.As described above, according to the present proposal, by installing the adjustment bolt (5) for adjusting the body seat ring (2) mounted on the inner peripheral surface of the valve body (1) outside the valve body (1), It completely blocks leaks and can be easily adjusted externally even when a leak occurs during use, so it can be used semi-permanently.It has less fluid resistance than double disc butterfly valves, which can reduce costs and deliver fluids in pipelines. It is possible to reduce the capacity of pressurized driving pump motor and to provide double-sided pressure relief butterfly valve which is easy to maintain and use the valve.
