상기와 같은 본 고안의 작용은 다음과 같다.The operation of the present invention as described above is as follows.
도 4에 도시한 바와 같이, 버터플라이 밸브가 구비된 스트레이너(100)는 그 흡입연결부(112)에 유로를 개폐시키는 버터플라이 밸브가 일체로 형성되어 있으므로, 배관공사시에 별도로 밸브를 설치할 필요가 없게 된다.As shown in Figure 4, the strainer 100 with a butterfly valve is integrally formed with a butterfly valve for opening and closing the flow path in the suction connection portion 112, so there is no need to install a valve separately during piping work do.
그리고, 상기 스트레이너(100)는 그 내부에 설치된 스크린(120)를 교체하거나 이물질이 가득차 청소하고자 할 때에 먼저 손잡이부(200)를 작동시켜 디스크(210)에 의해 흡입관로(a)를 밀폐시키면 유체의 흐름이 차단되고, 이와 같은 상태에서 커버(130)를 해체하여 스크린(120)을 제거할 수 있는 것이다.In addition, when the strainer 100 replaces the screen 120 installed therein or attempts to clean the full of foreign matter, the strainer 100 first operates the handle part 200 to seal the suction pipe passage (a) by the disk 210. The flow of is cut off, and in such a state that the cover 130 can be removed to remove the screen 120.
이와 같이 스크린의 청소나 교체가 완료되면 다시 커버(130)를 조립하고 버트플라이 밸브장치(200)를 작동시켜 흡입관로(a)를 개방시키면 스트레이너를 내부로 유체가 유동되면서 이물질이 걸러지게 된다.As such, when the cleaning or replacement of the screen is completed, the cover 130 is assembled again, and the butt valve device 200 is operated to open the suction pipe (a) so that foreign matter is filtered while the fluid flows into the strainer.
상기와 같은 본 고안에 따른 버터플라이밸브를 갖춘 스트레이너에 의하면, 스트레이너의 흡입측에 별도의 밸브 설치가 요구되지 않으므로 자재비와 설치비가 감소되고 이에 따라 공사기간이 단축되며 협소한 공간내에서도 용이하게 작업할 수 있게 되어 작업성이 향상되는 매우 유용한 고안이다.According to the strainer having a butterfly valve according to the present invention as described above, since the installation of a separate valve on the suction side of the strainer is not required, the material cost and installation cost is reduced, thereby reducing the construction period and easy to work in a narrow space It is a very useful design that can improve workability.
