본 고안은 수원지등의 대구경수도관에 사용되는 버터프라이 밸브를 개량하여 밸브의 개폐작용이 원활하게 이루워지도록함과 동시에 부관변의 밸브시이트와 디스크링의 마모율을 감소시키고, 메인디스크와 보조디스크를 개폐하는 밸브로드를 각각 별도록 독립설치하여 메인밸브로드의 단면적이 작게 형성되게 하므로서 송수관내에서의 유체의 마찰저항을 감소시켜 송수효율을 향상시키고, 밸브의 사용수명을 연장시키도록 하기 위한 것이다.The present invention improves the butterfly valves used in large diameter water pipes such as water sources to facilitate the opening and closing of the valves, and at the same time reduces the wear rate of the valve seats and disc rings on the side pipes, and opens and closes the main and auxiliary disks. The valve rods are separately installed so that the cross-sectional area of the main valve rod is made small, thereby reducing the frictional resistance of the fluid in the water pipe, thereby improving water supply efficiency and extending the service life of the valve.
종래 대형의 버터프라이밸브를 장설함에 있어서는 밸브의 개폐작동을 용이하게 하기위하여 메인밸브외에 보조밸브를 설치하는바, 일반적으로 보조밸브는 주류관에서 분기된 소구경부관(副管)에 별도의 소형 밸브를 장치하거나, 또는 제5도에 도시한 바와같이 메인 디스크의 중심부에 보조디스크를 설치하고 보조디스크의 밸브로드가 메인디스크의 밸브로드속으로 삽입되게 구성하는 것이었는바, 부관을 분기시킨 형태의 것에 있어서는 주류관에 부관을 연결하는 작업이 곤란하고 용접부위가 쉽게 파손되므로서 설치와 보수관리상 곤란한 점이 많은것이었고, 메인디스크와 보조디스크의 밸브로드를 동심축으로 형성시킨 것에 있어서는 밸브를 개폐할때마다 보조디스크와 메인디스크가 4회식 반복하여 접촉마찰하게되므로서 보조디스크의 밸브시이트 및 디스크링이 쉽게 마모되어 밸브의 사용수명을 단축시키는 원인이 되었던 것이다.In the case of installing a large butterfly valve in the related art, in order to facilitate the opening and closing operation of the valve, an auxiliary valve is installed in addition to the main valve. In general, the auxiliary valve is separately small in a small diameter pipe branch branched from the mainstream pipe. As shown in FIG. 5, the auxiliary disk was installed in the center of the main disk and the valve rod of the auxiliary disk was inserted into the valve rod of the main disk. In this case, it was difficult to connect the sub pipes to the liquor pipe, and the welding parts were easily damaged, which made it difficult for installation and maintenance.In the case where the valve rods of the main disk and the auxiliary disk were formed concentrically, the valve was opened and closed. Whenever the auxiliary disk and the main disk are contacted and rubbed repeatedly for four times, And the ring disc is easy to wear has been a cause of shortening the service life of the valve.
즉, 제5도에 도시한 바와같이 메인디스크(1)와 보조디스크(2)의 밸브로드(3) (4)를 동심축으로 형성하는 경우에는 밸브를 열때 먼저 보조디스크(2)를 열게되므로 이때 보조디스크(2)의 밸브시이트(2a)와 디스크링(2b)이 마찰되고, 보조디스크 (2)가 열린 후 메인디스크(1)를 열면 메인디스크(1)가 전개되는 위치에서 보조디스크(2)는 닫힌상태가 되므로 보조디스크(2)의 밸브시이트와 디스크링이 다시 마찰하게되는 것이고, 반대로 밸브를 닫을때에는 먼저 메인디스크를 닫을때와 보조디스크를 닫을때 각각 마찰되므로서 결국 밸브를 1회개폐할때마다 보조디스크(2)의 밸브시이트(2a)와 디스크링(2b)은 각각 4회식 접촉마찰되므로서 마모율이 높게됨과 동시에, 보조디스크(2)의 개변초기와 폐변말기에는 밸브시이트(2a)와 디스크링(2b) 사이의 좁은 간극으로 고압수가 분출하게되어 분출되는 물과 접촉마찰되는 시간이 많게되므로 밸브시이트(2a)및 디스크링(2b)의 마모와 변형이 촉진되고 이에따라 밸브의 기능을 저하시키고, 사용수명을 단축시키게되는 원인이 되었던 것이다.That is, as shown in FIG. 5, when the valve rods 3 and 4 of the main disk 1 and the auxiliary disk 2 are formed concentrically, the auxiliary disk 2 is first opened when the valve is opened. At this time, the valve seat 2a of the auxiliary disk 2 and the disk ring 2b are rubbed, and when the auxiliary disk 2 is opened and the main disk 1 is opened, the auxiliary disk ( 2) is in the closed state, the valve seat and the disc ring of the auxiliary disk (2) is rubbed again. On the contrary, when closing the valve, the valve is first frictioned when the main disc is closed and the auxiliary disc is closed. Each time the valve seat 2a and the disc ring 2b of the auxiliary disc 2 are subjected to four-time contact friction, the wear rate is high, and at the beginning and the closing period of the auxiliary disc 2, the valve seat High pressure water in a narrow gap between (2a) and disc ring (2b) As a result of the increase in the time of contact friction with the ejected water, the wear and deformation of the valve seat 2a and the disc ring 2b are promoted, thereby degrading the function of the valve and shortening the service life. .
본 고안은 이와같은 종래의 결점을 제거하여 메인디스크에 부관작용을 하는 보조디스크를 장치하되, 메인디스크와 보조디스크의 밸브로드를 각각 독립되게 설치하므로서 메인디스크를 개폐하때에는 보조디스크와 접촉마찰이 발생하지 않도록 한 것으로서 이하도면에 따라 상세히 설명하면 다음과 같다.The present invention removes these conventional drawbacks, but installs an auxiliary disk that acts as a subsidiary action on the main disk, and separately installs the valve rods of the main disk and the auxiliary disk, so that the auxiliary disk and the contact friction can be used when opening and closing the main disk. It will be described in detail as follows to avoid the occurrence of the following.
메인디스크(1)에 형성된 통수공(5)을 보조디스크(2)로 개폐하게된 것에 있어서, 메인디스크(1)의 주연부와 근접된 위치에 통수공(5)을 형성하여 통수공(5)을 개폐하는 보조디스크(2)를 메인디스크(1)의 회전방향면과 반대방향면인 배면부에 설치하고, 보조디스크(2)의 밸브로드(4)가 메인디스크(1)의 밸브로드(3)와 평행되게 구성하여서 된것이다. 도면중 부호1a는 메인디스크(1)의 밸브시이트, 1b는 메인디스크(1)의 디스크링, 2a는 보조디스크(2)의 밸브시이트, 2b는 보조디스크(2)의 디스크링이다.In opening and closing the water supply hole 5 formed in the main disk 1 by the auxiliary disk 2, the water supply hole 5 is formed by forming the water supply hole 5 at a position proximate to the periphery of the main disk 1. The auxiliary disk (2) for opening and closing the auxiliary disk (2) is installed on the rear surface opposite to the rotational surface of the main disk (1), and the valve rod (4) of the auxiliary disk (2) is the valve rod (3) of the main disk (1). It is configured to be parallel to). In the figure, reference numeral 1a denotes a valve seat of the main disc 1, 1b denotes a disc ring of the main disc 1, 2a denotes a valve seat of the subsidiary disc 2, and 2b denotes a disc ring of the auxiliary disc 2.
이와같이 구성된 본 고안은 밸브를 열어 통수하고자할때에는 제3도에 도시한 바와같이 우선 보조디스크(2)를 열면 통수공(5)을 통하여 송수관내의 고압수가 유출되므로서 송수관내의 압력이 감소되는 것이고, 이에따라 제4도에 도시한 바와같이 메인디스크(1)를 용이하게 열 수 있게되는 것이며, 단수하고자 할때에는 통수때와는 반대로 메인디스크(1)를 먼저 닫은후에 보조디스크(2)를 닫게되는 것인바, 본 고안에서는 메인디스크(1)와 보조디스크(2)의 밸브로드가 각각 분리된 상태로 독립하여 설치되어 있고, 보조디스크(2)가 메인디스크(1)의 중심에서 벗어난 위치에 있는 것이므로 메인디스크(1)를 연상태에서는 보조디스크(2)와 통수공(5)사이의 간격이 크게 벌어지게 되는 것이며, 이에 따라 종래의 것에서 볼 수 있는 밸브시이트 (2a)와 디스크링(2b)사이에 발생되는 좁은 간극으로 고압수가 고속으로 분사되는 현상을 방지하여 분출수와의 마찰로인한 밸브시이트(2a)와 디스크링(2b)의 마모율을 감소시킬 수 있게되는 것이며, 보조디스크(2)의 밸브시이트(2a)와 디스크링(2b)의 마찰을 메인디스크(1)의 개폐와는 관계없이 보조디스크(2)를 개폐할때에만 발생하게되는 것이어서 밸브시이트(2a)와 디스크링(2b)의 마모율이 크케 감소되는 것이고, 이에따라 빈번한 보수교체작업을 하지않더라도 높은밀폐도를 장기간 유지하게 되어 밸브의 사용수명을 연장시킬 수 있는 작용효과를 나타내게 되는 것이다.The present invention configured as described above is to open the valve, as shown in FIG. 3, first open the auxiliary disk (2), the high pressure water in the water pipe through the water hole (5) is discharged to reduce the pressure in the water pipe, Accordingly, as shown in FIG. 4, the main disk 1 can be easily opened, and when it is desired to singularly, the main disk 1 is first closed, and then the auxiliary disk 2 is closed, as opposed to water supply. Invar, in the present invention, since the valve rods of the main disk (1) and the auxiliary disk (2) are installed independently of each other, the auxiliary disk (2) is located at a position away from the center of the main disk (1) In the state where the main disk 1 is opened, the gap between the auxiliary disk 2 and the water passage 5 is greatly widened, and thus, between the valve seat 2a and the disk ring 2b, which can be seen in the related art. It is possible to reduce the wear rate of the valve seat 2a and the disc ring 2b due to the friction with the jetted water by preventing the high pressure water from being injected at a high speed with a narrow gap generated, and the valve of the auxiliary disc 2 The friction between the sheet 2a and the disc ring 2b is generated only when the auxiliary disc 2 is opened and closed irrespective of the opening and closing of the main disc 1, so that the valve seat 2a and the disc ring 2b The wear rate is greatly reduced, and accordingly, the high sealing degree is maintained for a long time even without frequent maintenance and replacement, which has the effect of extending the service life of the valve.
