Description

격막의 파손을 방지할 수 있는 밀폐형 팽창탱크{Closed expansion tank capable of preventing breakage of diaphragm}Closed expansion tank capable of preventing breakage of diaphragm}

본 발명은 수충격 방지용 밀폐형 팽창탱크에 관한 것으로, 더욱 상세하게는 격막으로 유입되는 날카로운 금속류의 이물질을 파손방지부재의 자력에 의해 사전에 차단하여 격막의 파손을 방지할 수 있는 밀폐형 팽창탱크에 관한 것이다.The present invention relates to a hermetic expansion tank for preventing water shocks, and more particularly, to an hermetic expansion tank capable of preventing the breakage of the diaphragm by blocking foreign substances of sharp metals flowing into the diaphragm in advance by the magnetic force of the damage preventing member. will be.

일반적으로 밀폐형 팽창탱크란, 배관의 압력을 조절하기 위해 사용하는 안전장치로서, 배관의 압력이 낮을 경우 밀폐형 팽창탱크 내부의 유체를 배관으로 이송하고, 배관의 압력이 높을 경우에는 배관의 유체를 밀폐형 팽창탱크의 내부로 이송하도록 구성된다. 이러한 밀폐형 팽창탱크는 물과 공기가 접촉하지 않도록 내측에 Butyl Rubber, EPDM 등의 고무재질로 이루어진 격막(Bladder, Diaphragm)이 구비되어 있다.In general, a closed expansion tank is a safety device used to control the pressure of a pipe. When the pressure of the pipe is low, the fluid inside the sealed expansion tank is transferred to the pipe. When the pressure of the pipe is high, the fluid of the pipe is sealed. It is configured to convey the inside of the expansion tank. The hermetic expansion tank is provided with a membrane (Bladder, Diaphragm) made of rubber materials such as Butyl Rubber, EPDM so that water and air do not contact.

그러나 종래의 격막은 고무재질로 이루어져 강도가 약하기 때문에 장시간 사용하거나 내부에 이물질이 유입되면 파손될 우려가 있다. 이렇게 격막이 파손될 경우에는 압축성 유체는 배관중에 흘러들거나 녹아들게 되고, 팽창탱크의 내부는 비압축성 유체가 오염되거나 가득 찬 상태가 될 수 있다. 이러한 경우 온도 변화에 따른 배관계 및 팽창탱크 내의 비압축성 유체가 팽창하게 되고, 이 팽창된 비압축성 유체는 결국 배관계의 압력을 급격히 상승시키게 되어 배관계의 파손과 기기의 고장원인이 되는 문제점이 있다.However, since the conventional diaphragm is made of a rubber material and has a low strength, there is a risk that the diaphragm may be damaged if it is used for a long time or foreign substances are introduced therein. When the diaphragm is damaged in this way, the compressive fluid flows into or melts in the pipe, and the inside of the expansion tank may be contaminated or full with the incompressible fluid. In this case, the incompressible fluid in the piping system and the expansion tank expands due to the temperature change, and the expanded incompressible fluid eventually raises the pressure of the piping system rapidly, causing problems of breakage of the piping system and failure of the equipment.
