본 고안은 수직개폐 구조로 된 버터플라이 밸브에 관한 것으로 구체적으로는 밸브가 유체압력에 의해 임의로 개방되는 것을 방지하고자 함을 목적으로 하는 것이다.The present invention relates to a butterfly valve having a vertical opening and closing structure, and specifically to the purpose of preventing the valve from being opened arbitrarily by the fluid pressure.
종래 밸브를 수직으로 개폐하는 버터플라이 밸브의 개폐구조는 일본 실용신안출원공개소 54-94631호와 같이 변판을 축설한 밸브축의 상부에 스크류를 형성하고 스크류에 경사안내홈이 곡설된 승강나합관을 나사끼움하되 경사안내홈에 볼을 끼워 변판이 회전개폐되게 한 구조이므로 변판이 유체의 강한 압력에 의해 임의로 회전되어 개폐되므로서 유체가 누설되는 등 밸브의 기능을 완벽하게 할 수 없는 폐단이 있었다.The opening and closing structure of a butterfly valve that vertically opens and closes a valve is formed in the upper part of the valve shaft in which the valve is arranged as shown in Japanese Utility Model Application Publication No. 54-94631. There was a closed end where the valve could not be perfectly functioned as the valve was inserted into the inclined guide groove so that the valve was opened and closed by rotating the valve.
본 고안은 이와같은 점을 감안하여 변판이 축설된 밸브축이 핸들의 회전에 의해서만 회전되게 하므로서 종래의 결점을 일소한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been made in view of the above point is that the valve shaft is installed in the valve plate is rotated only by the rotation of the handle to eliminate the conventional drawbacks in detail according to the accompanying drawings as follows.
버터플라이 밸브(1)의 후렌지(2)상면에 원통형 기어박스(3)를 고정 설치하여 그 상부중심에 핸들축(5)을 하부의 스크류(4)가 기어박스(3)의 내부에 삽설되도록 축설하고 승강나합판(6)의 하단내면에 볼(10)이 유착된 작동간(11)을 입설시켜 볼(10)을 밸브측(1')과 이의 양측에 축착시킨 회전관(12)의 경사안내홈(13)에 유삽시킨 것에 있어서 승강나합관(6)의 양측에 회전방지용 돌기(7)를 대설시켜 이를 기어박스(3)의 내측에 일체로 형성한 안내판(8)의 안내홈(9)에 승강자재되게 유삽시켜서 됨을 특징으로 하는 것이다.The cylindrical gear box 3 is fixedly installed on the upper surface of the flange 2 of the butterfly valve 1 so that the handle shaft 5 is inserted at the upper center thereof so that the lower screw 4 can be inserted into the gear box 3. Of the rotary tube 12 in which the ball 10 is condensed on the valve side 1 'and both sides thereof by placing the operating section 11 in which the ball 10 is adhered to the lower end inner surface of the elevating or plywood 6. The guide groove of the guide plate 8 in which the anti-rotation protrusions 7 are installed on both sides of the elevating or inclined pipe 6 in a manner inserted into the inclined guide groove 13 and integrally formed inside the gear box 3. 9) It is characterized by the fact that it is driven and lifted freely.
도면중 미설명부호 14는 핸들축(5)의 상단에 설치한 핸들이다.In the figure, reference numeral 14 is a handle installed on the top of the handle shaft (5).
이와같이 된 본 고안은 핸들축(5)의 스크류(4)에 승강나합관(6)을 나사끼움하되 양측의 돌기(7)를 안내판(8)의 안내홈(9)에 유삽시킨 것이므로 핸들(14)을 이용하여 핸들축(5)을 회전시키면 핸들축(5)은 제자리에서 회전되는 반면에 핸들축(5)하부의 스크류(4)에 나삽시킨 승강나합관(16)은 돌기(7)를 매개로 안내판(8)의 안내홈(9)을 따라 상하로 승강자재된다.In this way, the present invention is a screw 14 of the elevating or joining pipe (6) to the screw (4) of the handle shaft (5) because the projections (7) on both sides of the guide groove (9) of the guide plate (8) because the handle 14 When the handle shaft 5 is rotated by using the handle shaft 5, the handle shaft 5 is rotated in place, while the lifting and lowering screw tube 16 which is screwed into the screw 4 under the handle shaft 5 has the protrusion 7 The material is lifted up and down along the guide groove 9 of the guide plate 8.
그리고 승강나합관(6)에는 작동간(11)이 주립되어 그 하단 내면에 유착시킨 볼(10)이 밸브축(1')에 축착된 회전관(12)의 경사안내홈(13)에 유삽되어 있으므로 승강나합관(6)이 핸들축(5)의 회전으로 상하 승강되면 이에 연결된 2작동간(11)도 동시에 승강되므로 하단의 볼(10)이 경사안내홈(13)에 유삽된 회전관(12)은 작동간(11)의 승강력에 의해 강제로 경사안내홈(13)의 나선 각도를 따라 최대 180°까지 회전하게 되므로 이에 축착된 밸브축(1')이 회전하여 밸브를 개폐하게 되는 것이다.In addition, the elevating or joining pipe 6 has an operation period 11 in contact with the lower end inner surface. The ball 10 is inserted into the inclined guide groove 13 of the rotary tube 12 which is fixed to the valve shaft 1 '. Since the elevating or joining pipe 6 is moved up and down by the rotation of the handle shaft 5, the two operation sections 11 connected thereto are also simultaneously raised, so that the lower ball 10 is inserted into the inclined guide groove 13 by the rotary pipe. 12 is forcibly rotated up to 180 ° along the helix angle of the inclined guide groove 13 by the lifting force of the operation 11, so that the valve shaft (1 ') constricted thereto rotates to open and close the valve. Will be.
여기서 밸브축(1')에 축착된 회전관(12)과 작동간(11)을 매개로 연결된 승강나합관(6)은 그 양측의 돌기(7)가 기어박스(3)와 일체로 된 안내판(8)의 안내홈(9)에 끼워져 있으므로 핸들축(5)의 회전시 돌기(7)가 안내홈(9)을 따라 상하로 승강작동만 될 뿐 회전될 우려는 없으므로 강력한 유체의 압력에 의해 변판이 임의로 회전되어 개폐되는 종래의 폐단을 해소할 수 있는 것이다.Here, the elevating or inferior pipe 6 connected through the rotary tube 12 and the operation 11 connected to the valve shaft 1 'has a guide plate in which the projections 7 at both sides thereof are integrated with the gear box 3. Since it is fitted in the guide groove 9 of (8), when the handle shaft 5 is rotated, the projection 7 only moves up and down along the guide groove 9, and there is no danger of rotation. It is possible to solve the conventional closed end that the side plate is rotated arbitrarily.
이와같이 본 고안은 수직개폐식 버터플라이 밸브에 있어 스크류(4)와 나사결합된 승강나합관(6)을 회전되지 못하도록 제어하므로 유체의 강력한 압력에 의해 변판이 회전되는 것을 방지하여 밸브의 개폐를 정확히 할 수 있는 효과가 있다.In this way, the present invention controls the vertically-opening butterfly valve to prevent the screw 4 and the screwed up / down pipe 6 screwed in from rotating, thereby preventing the valve from being rotated by the strong pressure of the fluid, thereby precisely opening and closing the valve. It can be effective.
