본 고안은 더블 버터플라이밸브에 관한 것으로서, 본 고안의 특징은, 한쌍으로 형성된 디스크에 소형밸브를 형성하여 개폐시에 1차로 소형밸브의 디스크를 열어 압력을 감소시킨후 2차로 메인밸브의 디스크를 열 수 있도록 하여 적은 힘으로 개폐시킬 수 있도록 한데 있다.The present invention relates to a double butterfly valve, the feature of the present invention is to form a small valve in a pair of disk formed by opening and closing the disk of the small valve primarily in opening and closing to reduce the pressure, and then It can be opened and closed with less force.

더블 버터플라이밸브의 디스크는 두개의 디스크로 형성되었으므로 단일의 디스크로 형성된 버터플라이밸브에 비하여 디스크와 밸비시이트의 밀착력이 2배로 발휘되게 되므로 누수차단효율은 향상된다 하겠으나, 그러나 다스크를 개폐시키고자 할때는 단일의 디스크에 비하여 2배의 개폐력을 요하게 되고, 특히, 대형밸브는 큰힘의 조작력을 요하게 되었다. 따라서 종래의 더블 버터 플라이밸브를 개폐시키는데는 많은 힘을 요하게 되어 원활한 개폐조작이 이루어지지 못하게 되는 결점이 있었다.Since the disk of the double butterfly valve is formed of two disks, the adhesion between the disk and the valve seat is doubled compared to the butterfly valve formed of a single disk, so that the leakage blocking efficiency is improved. In this case, the opening and closing force of a single disc is required twice as much, and in particular, a large valve requires a large force of operation force. Therefore, it requires a lot of power to open and close the conventional double butterfly valve has a drawback that the smooth opening and closing operation is not made.

본 고안은 상기와 같은 결점을 해결하기 위하여 메인밸브의 디스크에다 소형 밸브를 설치하여 메인밸브의 디스크를 열고자 할때는 먼저 소형밸브의 디스크를 열어 압력을 감소시킨 다음, 한쌍으로 형성된 메인밸브의 디스크를 적은 힘으로 열 수 있도록 한 더블 버터플라이밸브를 안출하게 된 것인데, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above drawbacks, the small valve is installed on the disc of the main valve to open the disc of the main valve. The double butterfly valve was made to open with a small force, which will be described in detail by the accompanying drawings as follows.

양측 프랜지(1A)(1B)를 형성한 메인밸브(1)에 고무제로 된 밸브시이트(3A)(3B)를 리테이너(2A)(2B)로 고정하고, 디스크시이트(6)를 고정한 한쌍의 디스크(4A)(4B)로 된 디스크(4)의 축(5A)(5B)을 메인밸브(1)의 축지지관(101)(102)에 유착하여 축(5B)을 회전시켜 디스크(4)를 개폐시킬 수 있도록 하고, 축(5A)의 중앙 및 축지지관(101)에는 축 (13)을 관통시켜 축지지관(101)의 프랜지(101A)에 밀폐카버(16)를 볼트(15A) 및 너트(15B)로 고정하고, 밀폐카버(16)의 프랜지(16A)에는 여러개의 톱니(17A)를 형성한 조절판(17)을 볼트(18A) 및 너트(18B)로 고정하여 조절판(17)상부로는 레버 (19B)를 형성한 레버볼트(19A)를 끼워 고정너트(20)로 고정하고, 레버(19B)에는 걸림편(21A)을 형성한 손잡이(21)를 핀(22)으로 유착하여 스프링(23)으로 탄력시켜서 걸림편(21A)를 톱니(17A)에 걸 수 있도록 하여서된 공지의 것에 있어서, 양 디스크(4A)(4B)에는 고정구(9A)(9B)와 밸브시이트(8)를 볼트(10A) 및 너트(10B)로 고정하고, 축(13)의 프랜지(13A)에는 디스크(11)를 고정하여 소형밸브(7)를 형성하여서 된 축(12)의 프랜지(12A)를 볼트(14A) 및 너트(14)로 고정하여 구멍(4A')(4B')을 개폐시킬 수 있도록 한 것이다.A pair of disks on which the valve seats 3A and 3B made of rubber are fixed to the main valve 1 on which the two flanges 1A and 1B are formed with retainers 2A and 2B, and the disk sheet 6 is fixed. The shafts 5A and 5B of the disk 4 made of 4A and 4B are brought into contact with the shaft support tubes 101 and 102 of the main valve 1 to rotate the shaft 5B to rotate the disk 4. Opening and closing, through the shaft (13) through the center and shaft support tube 101 of the shaft (5A), the sealing cover 16 to the flange 101A of the shaft support tube 101 bolts (15A) and nuts ( 15B), and the throttle plate 17, which has a plurality of teeth 17A, is fixed to the flange 16A of the closed cover 16 with bolts 18A and nuts 18B, and above the throttle plate 17. The lever bolt 19A formed with the lever 19B is inserted and fixed with the fixing nut 20, and the lever 21B has the handle 21 formed with the engaging piece 21A with the pin 22 to hold the spring 22. 23) to make the hook 21A hook onto the teeth 17A In this case, the fasteners 9A and 9B and the valve seat 8 are fixed to both disks 4A and 4B with bolts 10A and nuts 10B, and the disks are provided on the flanges 13A of the shaft 13. (11) can be fixed to form a small valve (7), the flange (12A) of the shaft 12 can be fixed with the bolt (14A) and the nut (14) to open and close the holes (4A ') (4B'). It would be.

미설명부호 24는 부싱이다.Reference numeral 24 is a bushing.

이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as follows.

디스크(4)를 열고자 할때는 먼저 손잡이(21)를 제3도의 실선화살표방향으로 상향시키게 되면, 손잡이(21)는 핀(22)을 축점으로 하여 회전되어 걸림편(21A)은 조절판(17)의 톱니(17A)에서 빠지게 된다.When opening the disc 4, first, when the handle 21 is raised in the solid arrow direction of FIG. 3, the handle 21 is rotated with the pin 22 as the axial point so that the locking piece 21A is the adjustment plate 17. The tooth 17A is missing.

상기의 상태에서 레버(19B)를 회전시키게 되면 레벌볼트(19A)의 사각구멍에 끼워진 축(13)은 회전하게 되고, 이에 따라 축(13)의 프랜지(13A)에 프랜지(12A)가 볼트(14A) 및 너트(14B)로 결합된 축(12)의 회전에 의하여 소형밸브(7)의 디스크(11)는 열려져 유체는 소형밸브(7)를 통하여 흐르게 되어 디스크(4)에 가해지는 고압의 유체는 감압되게 되는데, 상기의 작동에 있어 레버(19B)를 회전시켜 손잡이(21)를 놓게되면 스프링(23)의 탄발력에 의하여 걸림편(21A)은 여러개의 톱니(17A)중 임의의 톱니(17A)에 걸려지게되고, 디스크(11)는 열린 상태로 유지되게 되는 것이다.When the lever 19B is rotated in the above state, the shaft 13 fitted into the square hole of the lever bolt 19A is rotated, so that the flange 12A is bolted to the flange 13A of the shaft 13. The disk 11 of the small valve 7 is opened by the rotation of the shaft 12 coupled with the 14A) and the nut 14B so that the fluid flows through the small valve 7 so that the high pressure applied to the disk 4 is increased. The fluid is to be reduced in pressure. In the above operation, when the lever 21B is rotated to release the handle 21, the catch piece 21A is caused by the spring force of the spring 23. It is caught by 17A, and the disk 11 is kept open.

상기의 상태에서 축(5B)을 회전시켜 디스크(4)를 열면 되는데, 소형밸브(7)로 유체압을 감소시킨 상태에서 열게 되므로 적은 힘으로 용이하게 열 수 있는 것이다.In the above state, the disk 5 may be opened by rotating the shaft 5B, but the small valve 7 may be opened in a state in which the fluid pressure is reduced, so that the disk 5B may be easily opened with a small force.

닫을때 역시 소형밸브(7)가 열린상태에서 디스크(4)를 닫은 후 소형밸브(7)의 디스크(11)를 닫으면 되므로 적은 힘으로 디스크(4)를 닫을 수 있는 것이다.When closing, the disk (4) can be closed with a small force since the disk (11) of the small valve (7) is closed after closing the disk (4) in the open state.

이와 같은 본 고안은 디스크(4)에 소형밸브(7)를 형성하여 소형밸브(7)로 고압의 유체압력을 일단 감압시킨 후 디스크(4)를 개폐시키게 되므로 적은 힘으로 디스크(4)를 개폐시킬 수 있는 효과가 있다.The present invention is to form a small valve (7) on the disk (4) to reduce the high pressure fluid pressure with the small valve (7) once to open and close the disk (4) to open and close the disk (4) with a small force It can be effected.
