Description

조립식 버터플라이 밸브{Knockdownable Butterfly Balve}Prefabricated Butterfly Valve {Knockdownable Butterfly Balve}

본 발명은 버터플라이 밸브에 관한 것으로, 더욱 상세하게는 설정 유량과 압력에 따라 디스크에 보강부재를 착탈하여 사용할 수 있도록 한 조립식 버터플라이 밸브에 관한 것이다. The present invention relates to a butterfly valve, and more particularly, to a prefabricated butterfly valve that can be used to attach and detach the reinforcing member to the disk according to the set flow rate and pressure.

일반적으로 버터플라이 밸브는 동일한 구경의 다른 밸브에 비해 무게가 가볍고 부피가 작으며 가격 경쟁력이 우수함과 아울러 조작력이 적게 드는 이점 때문에 광범위하게 사용되고 있고, 통상 내부가 빈 원형의 밸브 몸체 내부에 디스크를 설치하여 90°범위에서 회전시킴으로써 유체의 흐름을 차단하여 주는 역할을 하는 밸브이다.In general, butterfly valves are widely used due to their light weight, small size, excellent price competitiveness, and low maneuverability compared to other valves of the same diameter. It is a valve that serves to block the flow of fluid by rotating in the 90 ° range.

이러한 버터플라이 밸브는 설정 유량 및 설정 압력에 따라 밸브 규격이 정해져 있다. 따라서 설정 유량 및 설정 압력에 대응하여 버터플라이 밸브를 제작해야 하며, 동일한 관로 상에서 사용하는 유체의 설정 유량 및 압력이 가변되면 이에 맞는 버터플라이 밸브로 교체해야 하므로 교체 작업에 따른 비용과 노력이 많이 요구되는 문제가 있다. These butterfly valves have a valve specification determined by the set flow rate and the set pressure. Therefore, the butterfly valve must be manufactured according to the set flow rate and the set pressure, and if the set flow rate and pressure of the fluid used in the same pipe is changed, it needs to be replaced with the butterfly valve. There is a problem.
