Abstract

A disc exchange-type butterfly valve is provided to separate only a driving shaft combined with a disc from a butterfly valve through an opening of a valve, thereby exchanging the disc in no need of exchanging the whole valve and facilitating an assembly for exchanging the disc. A disc exchange-type butterfly valve comprises a main body of a valve, a driving shaft(20), a lid(30) and a disc. Fluid flows inside the main body of the valve which is penetrated from a right side to a left side. The driving shaft is perpendicularly installed between an axis supporting unit(11) and an opening(12) of the valve. The lid opens or closes the opening. The disc mounted in the driving shaft opens or closes a flow channel of the valve.

도 10 및 도 11을 참고하면, 관로 상에 설치된 본 발명의 디스크 교체형 버터플라이 밸브를 전부 교체하지 않고, 디스크만 교체하도록 관로의 양단부를 제수밸브 등으로 일시 차단시키게 된다.Referring to FIGS. 10 and 11, without replacing all of the disk replaceable butterfly valve of the present invention installed on the pipeline, both ends of the pipeline are temporarily blocked by a dividing valve or the like so as to replace only the disk.

이러한 상태에서 제1단계는, 밸브몸통(10)에 고정되어진 상부덮개(30)의 볼트를 분리하는 단계이다.In this state, the first step is to remove the bolt of the upper cover 30 fixed to the valve body (10).

제2단계는, 상부덮개(30)가 밸브몸통(10)에서 분리된 상태에서 구동축(20)을 디스크(40)에 대해 상부로 이송시킨 상태를 나타내고 있다.The second step is a state in which the drive shaft 20 is transferred to the upper portion with respect to the disk 40 in a state in which the upper cover 30 is separated from the valve body 10.

즉, 구동축(20)을 상부로 이송시키게 되면 스톱퍼(60)와 결합되어진 구동축(20)의 슬라이딩 홈(21)을 따라 구동축(20)이 상부로 이송되는 것이다. That is, when the drive shaft 20 is moved upward, the drive shaft 20 is moved upward along the sliding groove 21 of the drive shaft 20 coupled with the stopper 60.

이때 본 발명에 따른 축지지수단(50)의 일실시예의 축지지핀(51)은 전진시켜 구동축이 이탈이 용이하게 할 수도 있고, 다른 실시예의 축지지핀(51)은 탄성부배(51a)에 의해 탄력지지된 상태를 해제하기 위하여 축지지핀(51)을 구동축(20)의 요홈에서 이탈시키도록 하는 것이다.At this time, the shaft support pin 51 of one embodiment of the shaft support means 50 according to the present invention may be advanced to facilitate the separation of the drive shaft, the shaft support pin 51 of another embodiment is elastic by the elastic distribution (51a) The shaft support pin 51 is to be released from the groove of the drive shaft 20 to release the supported state.

제3단계는, 디스크(40)를 밸브몸통(10)의 개구면(12)을 통해 이탈시키도록 디스크(40)를 개구면(12)의 가로 폭(L)과 세로 폭(W)에 맞추도록 하는 것이다.In the third step, the disk 40 is aligned with the horizontal width L and the vertical width W of the opening surface 12 so that the disk 40 is separated through the opening surface 12 of the valve body 10. To do that.

제4단계는, 디스크(40)가 결합되어진 구동축(20)을 외부로 완전히 이탈되도록 한 상태를 나타내고 있는 것이다.The fourth step represents a state in which the drive shaft 20 to which the disk 40 is coupled is completely separated from the outside.

또한, 제4단계 이후에는 하부덮개(70)에 설치된 체크밸브(71)로 공기압을 제공하여 밸브몸통(10)의 하부에 적층되어진 이물질을 확산판(72)의 관통공을 통해 밸브몸통(10) 외측으로 이탈되도록 하는 것이다.In addition, after the fourth step, by providing the air pressure to the check valve 71 installed in the lower cover 70, the foreign matter stacked in the lower portion of the valve body 10 through the through hole of the diffusion plate 72, the valve body 10 ) Is to escape to the outside.
