수압제거식 버터플라이 밸브Pressure Relief Butterfly Valve

제 1 도는 본 고안의 수압 제거식 버터플라이 밸브를 보인 종단면도.1 is a longitudinal sectional view showing a hydraulic pressure relief valve of the present invention.

제 2a 도는 제 1 도의 A-A선 단면도, (b)는 본 고안의 요부의 단면 설명도.2A is a cross-sectional view taken along the line A-A of FIG. 1, (b) is a cross-sectional explanatory view of the main part of the present invention.

본 고안은 상하수도관에 관착되는 버터플라이 밸브에 있어서, 상하수를 송수코져 닫힌 밸브를 열고져, 밸브 디스크를 90도 회전 운동을 하게하는 회전축을 외부에서 돌리기 시작할때에 상수도관 상류측의 수압으로 막대한 수압이 걸려있는 디스크의 수압을 순식간에 감압 완화시켜 그 회전 축의 회전을 처음부터 수월하고 원활하게 회전될 수 있게한 수압제거식 버터플라이 밸브에 관한 것이다.The present invention is a butterfly valve that is connected to the water supply and sewage pipe, the water supply and drainage is closed by opening the closed valve, when the rotating shaft to rotate the valve disk 90 degrees from the outside when the external water pipe upstream side The present invention relates to a hydropneumatic butterfly valve that allows the hydraulic pressure of a disk subjected to hydraulic pressure to be reduced and reduced in an instant so that the rotation of the rotating shaft can be easily and smoothly rotated from the beginning.

종래 상하수도관에 관착된 버터플라이 밸브에 있어서, 상하수를 아래방향으로 통수시킬 때에는 밸브 본체외부에 착설된 개폐조작 장치의 회전축을 여는 방향으로 돌려서 회전축과 연결된 기어열을 경유하여 밸브축의 90도의 회전에 따라서 밸브축과 디스크가 일체로 고정되어, 밸브 디스크가 90도 회전운동을 하므로서 통수되게 하는 것인데, 이때 장기간 밀폐되었던 밸브 디스크는 항시 상류측의 큰 수압을 받아서 밸브 디스크가 밸브시이트에 압입 당하고 있는 것이어서, 밸브를 열고자할 시에는 개폐조작장치의 회전축에 매우 큰 힘이 소요되었던 결점이 있었다.In the butterfly valve conventionally connected to the water supply and sewage pipe, when the water and the sewage are passed downward, the valve is rotated in the direction of opening the opening and closing operation device installed on the outside of the valve body to rotate the valve shaft 90 degrees through the gear train connected to the rotation shaft. Therefore, the valve shaft and the disk are integrally fixed so that the valve disk can pass through as it rotates by 90 degrees. At this time, the valve disk, which has been closed for a long time, is always pressurized by the valve seat due to the large hydraulic pressure upstream. In order to open the valve, there was a drawback that a very large force was applied to the rotating shaft of the switching device.

종래에는 이러한 문제점을 조금이나마 해결하기 위하여 상하수도관에 관착된 버터플라이 밸브 전후에서 상하수도관에 보조관 및 보조 제수밸브를 설치하여, 관착된 버터플라이 밸브를 열고져 할시에는 우선, 보조관에 설치된 보호 제수밸브를 열어서 버터플라이 밸브의 디스크에 작용하는 수압을 감압, 완화시킨 후, 버터플라이 밸브를 열어서 통수하는 등 이중의 밸브 개폐작동이 필히 수반되었으며, 보조관 및 보조 제수밸브 설치에 다른 추가 경비와 버터플라이 밸브가 설치되는 밸브보호실이 보조관 및 보조 제수밸브의 설치에 따른 추가장소의 발생으로 밸브 보호실이 크게되어 시공경비가 과다하게 소요된 등 제반 어려운 문제점이 발생되었다.Conventionally, in order to solve this problem a little, the auxiliary pipe and the auxiliary water valve are installed in the water and sewage pipes before and after the butterfly valves connected to the water and sewage pipes. Opening the water valve and depressurizing and releasing the water pressure acting on the disc of the butterfly valve, and opening and passing the butterfly valve is necessary to double open and close the operation. The valve protection chamber in which the butterfly valve is installed has an additional place due to the occurrence of additional places due to the installation of the auxiliary pipe and the auxiliary water separator valve.

본 고안은 이와 같은 종래의 제반 문제점과 결점을 시정하고져 고안한 것으로서, 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to correct such problems and drawbacks of the prior art, as described in detail by the accompanying drawings as follows.

도면에 도시한 바와같이 환상 밸브 본체(1)에 원판형 밸브 디스크(2)가 회전축(3)으로 착설한 버터플라이밸브에 있어서, 밸브 디스크 회전축(3)의 일측단(3')에서 워엄(WORM)기어열(4)을 갖는 밸브 개폐조작장치(5)를 착설하여서 개폐 조작장치(5)의 회전축(6) 즉, 워엄(WORM)축의 개폐조작에 따라서 개폐조작장치(5)의 워엄 기어열(WORM GEAR)(4)을 통하여 밸브디스크 회전축(3)의 회전함에 따라서 디스크(2)가 함께 회전하게 되고, 밸브디스크(2)의 일측단(3')에 대칭으로 또 다른 회전축(3")을 밸브본체(1)에 고정시키고, 고정된 축(3")을 정점으로 밸브디스크 보스(BOSS)부 내부에 회전가능한 슬리브 베어링(7)과 습합하며, 제 2a 도 도시한 바와같이 고정된 축(3")의 습한 회전 부위에자형 수로(8)를 형성하고, 여기에 대응하여, 밸브디스크(2)가 회전축(3)일단(3')의 회전운동에 따라서 디스크 고무 시이트(9)가 밸브 본체시이트(10)를 벗어나는 일정회전 각도보다 작게 편심시켜 디스크(2)에 형성된 "/"자형수로(8')를 형성하여 수로(8)(8')가 편심 압접되도록 구성한 것이다.As shown in the figure, in the butterfly valve in which the disk-shaped valve disc 2 is installed on the annular valve body 1 as the rotating shaft 3, a worm (3 ') is provided at one end 3' of the valve disk rotating shaft 3. The worm gear of the opening / closing operation apparatus 5 is installed in accordance with the opening / closing operation apparatus 5 of the opening / closing operation apparatus 5, that is, the opening / closing operation of the WORM shaft. As the valve disc rotation shaft 3 rotates through the row gear 4, the disk 2 rotates together, and another rotation shaft 3 symmetrically to one end 3 ′ of the valve disk 2. &Quot;) is fixed to the valve body 1, and the fixed shaft 3 " vertices and engages with the rotatable sleeve bearing 7 inside the valve disc boss portion BOSS, and as shown in FIG. On the wet side of the shaft (3 ") The female channel 8 is formed, and correspondingly, the valve disc 2 is fixed so that the disc rubber sheet 9 leaves the valve body sheet 10 in accordance with the rotational movement of one end 3 'of the rotating shaft 3. It is configured such that the channels 8 and 8 'are eccentrically squeezed by forming an "/" shaped channel 8' formed in the disk 2 by eccentricity smaller than the rotation angle.

이와 같이 구성된 본 고안의 작용효과는 설명하면 다음과 같다.The effect of the present invention configured as described above is as follows.

제 2a 도에서 예시된 상태와 같이 밸브디스크가 닫힌 상태에서는 고정축(3")의 디스크보스(BOSS)죽, 습합회전부위에자형수로(8)과 여기에 대응하는 디스크에 형성된 "/"자형 수로(8')가 서로 어긋나게 되어 통상의 버터플라이 밸브와 같이 지수를 유지하게 되며, 밸브를 열고져 할시 즉, 개폐조작 장치(5)의 회전축(6)을 열고져 하는 방향으로 회전시키면 밸브 디스크 회전축(3)의 일축단(3')의 회전운동에 따라 디스크(2)가 함께 회전하므로서 제 2b 도에 예시된 상태와 같이, 디스크 고무시이트(9)가 밸브 본체시이트(10)을 벗어나기 이전에 디스크 회전축(3)에 대칭으로 설치된 또 다른 일측단 고정축(3")자형수로와 디스크에 형성된 "/"자형수로(8')가 일치조합되므로서 한개의 수로로 연결되어, 밸브디스크(2)에 작용하는 상하수와 상류측의 수압이 일체 형성된 수로(8)(8')를 통하여 감압되므로서 디스크(2)상하의 차압이 적어져 밸브 개폐에 작용하는 수력저항이 없어, 적은 힘으로도 개폐조작 장치의 회전축(6)의 조작이 용이하므로, 종래의 버터플라이 밸브의 개폐조작시보다 거의 힘이 들지 않는 효과가 있어서 상하수 유량의 유지 관리가 효율적이며, 기존의 수압 감압 완화용 보조관 및 보조 제수밸브의 설치 경비 감소와 밸브 보호실의 축소, 시설의 유지 보수 용이등 상당한 이점이 있다.As shown in FIG. 2A, when the valve disc is closed, the BOSS die and wet rotation part of the fixed shaft 3 " The male channel 8 and the "/" male channel 8 'formed in the disk corresponding thereto are shifted from each other to maintain the index as in a normal butterfly valve. When the rotating shaft 6 of (5) is rotated in the opening direction, the disks 2 rotate together according to the rotational movement of one shaft end 3 'of the valve disk rotating shaft 3, and the state illustrated in FIG. Similarly, another one end fixed shaft 3 "installed symmetrically with the disk rotation shaft 3 before the disk rubber sheet 9 leaves the valve body sheet 10. FIG. The water channel 8 formed by integrally combining the water channel and the "/" shape channel 8 'formed in the disk with one channel and having the upper and lower water acting on the valve disk 2 and the hydraulic pressure on the upstream side ( 8 '), the differential pressure on the top and bottom of the disc 2 decreases, so there is no hydraulic resistance acting on the valve opening and closing, and the operation of the rotary shaft 6 of the opening and closing operation device is easy even with a small force. It is less effective than opening / closing operation, so water and sewage flow rate maintenance is more efficient, and it reduces the installation cost of auxiliary pressure reducing valve and auxiliary water valve, reduces the valve protection room, and maintains the facility easily. There is a significant advantage.
