본 고안은 대기개방식 가스보일러에서 난방수의 팽창력을 흡수하는 팽창탱크에 설치되는 스트레이너에 관한 것으로서, 특히 기포포집기능을 겸비도록 고안된 팽창탱크의 스트레이너에 관한 것이다.The present invention relates to a strainer installed in an expansion tank that absorbs the expansion force of the heating water in the atmospheric opening gas boiler, and more particularly relates to the strainer of the expansion tank designed to have a bubble trapping function.
일반적으로 가스보일러에 있어 팽창탱크에는 환수되는 난방수가 유입되어 중간부에 설치되는 스트레이너를 통과하여 순환펌프를 통해 연교환기로 환수되도록 되어 있으며, 스트레이너는 이물질의 여과와 아울러서 기포를 파괴하여 소멸시키는 기능을 하므로서 열교환기로의 기포 유입을 방지하도록 되어 있다.In general, in the gas boiler, the returning water flows into the expansion tank, passes through a strainer installed in the middle, and is returned to the soft exchanger through a circulation pump.The strainer functions to destroy and destroy bubbles by filtration of foreign substances. By doing so, bubbles are prevented from entering the heat exchanger.
따라서 스트레이너는 전체가 미세한 구멍을 형성하는 스크린 구조로 이루어진 것이 팽창탱크내에 설치되도록 하는 것이 일반화되어 있으나, 이러한 스트레이너에 있어서는 난방환수관을 따라 팽창탱크내에 유입되는 기포가 팽창탱크 하부에서 곧바로 스트레이너를 통과할 수 있게 되기 때문에 스트레이너의 기능을 충실히 이행하지 못하는 문제가 초래되었다.Therefore, it is common that the strainer has a screen structure in which the entire hole is formed in the expansion tank. However, in such a strainer, air bubbles introduced into the expansion tank along the heating return pipe pass directly through the strainer from the bottom of the expansion tank. Being able to do so caused a problem of not fulfilling the function of the strainer.
본 고안은 상기와 같은 종래의 문제점을 감안하여, 난방수를 따라 팽창탱크내로 유입되는 기포가 스트레이너에 의해 포집될 수 있도록 하므로서 기포 제거 효율을 보다 증대시킬 수 있도록 하려는데 그 목적이 있다.The present invention has been made in view of the conventional problems as described above, so that the air bubbles introduced into the expansion tank along the heating water can be collected by the strainer to increase the bubble removal efficiency more.
상기 목적을 달성시키기 위하여, 본 고안은 스트레이너의 상,하부에 폐쇄막이 형성되도록 하거나 또는중간부의 스크린공보다 매우 작은 메쉬(mesh)로 형성되는 작은 스크린부가 하부에 형성되도록 하므로서 기포 포집기능이 부여되도록 한점에 그 특징이 있는 것으로서, 이하 첨부된 실시도면에 의거하여 보다 상세히 설명하면 다음과 같다.In order to achieve the above object, the present invention provides a bubble trapping function by forming a closed film on the upper and lower portions of the strainer or by forming a small screen portion formed at a lower portion of the middle of the screen hole than a screen hole in the middle portion. As one feature as possible, described in more detail on the basis of the accompanying drawings as follows.
본 고안에 따른 스트레이너(10)는 사각형태를 이루며 중간부에는 스크린부(11)를 형성하고 있고, 상기 스크린부(11) 상, 하측에는 상,하부 폐쇄막(12)(12')을 형성하도록 되어 있다.The strainer 10 according to the present invention has a rectangular shape and forms a screen portion 11 at an intermediate portion, and forms upper and lower closure films 12 and 12 ′ on the upper and lower sides of the screen portion 11. It is supposed to be.
상기, 상,하부폐쇄막(12)(12')에 있어 상부폐쇄막(12)보다 하부폐쇄막(12')이 더욱 높은 크기를 이루도록 되어 있다.In the upper and lower closed membranes 12 and 12 ', the lower closed membrane 12' is formed to have a higher size than the upper closed membrane 12.
따라서 스트레이너(10)는 덮개(2)를 구비하는 팽창탱크(1) 내부의 안내가이드홈(3)에 삽입되어 중간부에 설치되므로서, 팽창탱크(1) 하부에 구비하는 환수입구(4)와 환수출구(4') 사이에 설치된다.Therefore, the strainer 10 is inserted into the guide guide groove 3 in the expansion tank 1 having the cover 2 and installed in the middle portion, so that the inlet 4 provided below the expansion tank 1 is provided. And between the return outlet 4 '.
그러므로 본 고안은 환수입,출구(4)(4')사이에 스트레이너(10)의 높은 크기의 하부폐쇄막(12')이 위치하여 가로막히는 상태가 되므로서 환수입구(4)로 유입되는 난방수가 하측부분을 통해 곧바로 환수출구(4')쪽으로 흘러가지 못하는 차폐상태를 이루게 된다.Therefore, the present invention has a high level of the lower closure membrane 12 'of the strainer 10 between the inlet and outlet (4) (4') is placed in the state of being blocked, the heating flows into the inlet (4) The water flows through the lower part and forms a shielding state that does not flow directly to the return outlet 4 '.
따라서 난방수에 포함하고 있는 기포가 환수입구(4)로 곧바로 유입되지 못하고 위쪽으로 포집되는 상태가 되어 중간부의 스크린부(11)를 통과하여야 하므로써 스크린부에서 포집되어 걸러지며, 그만큼 팽창탱크(1)내부에서의 순환경로가 길어지게 되는 동시에 체류시간이 증가하게 되기 때문에 기포의 제거효율이 높아지게 되는 것이다.Therefore, the bubbles contained in the heating water are collected in the screen part by passing through the screen part 11 of the middle part without being directly flowed into the return inlet 4 and passing through the screen part 11, and thus the expansion tank 1 Since the circulation path in the inside becomes longer and the residence time increases, the bubble removal efficiency is increased.
또한, 환수입구(4)로 유입되는 난방수는 압력이 높으므로 수면위로 쏟구쳐 오르게 되며, 아울러서 스트레이너(10)의 상부폐쇄막(12)은 이러한 솟구쳐 오르는 난방수가 곧바로 스트레이너(10)를 통과하지 못하게 차단하여 다시 중간부로 떨어지도록 하므로서 기포가 중간부로 포집되도록 하여 기포 제거 효율 증대를 도모하게 된다.In addition, the heating water flowing into the return inlet (4) is high because the pressure is spilled on the water surface, and the upper closed film 12 of the strainer 10 is such that the rising heating water does not immediately pass through the strainer (10) By blocking it so that it falls back to the middle part, bubbles are collected in the middle part, thereby increasing the bubble removal efficiency.
한편, 본 고안에 있어 스트레이너(10)의 하부폐쇄막(12') 대신에 제4도의 예시와 같이 중간부의 스크린부(11)보다는 더욱 메쉬가 작은 폐쇄용스크린부(12a)를 형성시키도록 하므로서 기포포집기능을 가지도록 할수 있다. 이 경우 폐쇄용스크린부(12a) 메쉬가 매우 작기 때문에 환수입구(4)로 유입되는 난방수가 환수출구(4')쪽으로 곧바로 유입되지 않고 상부로 유도되면서 기포포집이 되게 되므로 동일한 기포제거효율 증대를 도모하게 된다.Meanwhile, in the present invention, instead of the lower closed film 12 'of the strainer 10, as shown in FIG. 4, the screen screen 12a having a smaller mesh than the screen part 11 of the middle part is formed. It can have a bubble collection function. In this case, since the closing screen part 12a mesh is very small, the heating water flowing into the return inlet 4 is not directly flowed toward the return outlet 4 'and is led to the upper air bubbles, thereby increasing the same bubble removal efficiency. It is planned.
이상의 설명에 따르면 본 고안에 의해 팽창탱크에서의 기포포집 기능이 스트레이너가 부가되기 때문에 기포제거효율증대를 도모하므로서 환수출구로의 기포유입이 상대적으로 감소하게 되어 순환펌프로 흡입되는 공기양이 감소하여 펌프능력저하 방지와 더불어서 열교환기로 흡입되는 공기양이 감소하게 되므로 공기 유입에 의한 비등음발생이 없게 되므로서 열교환기의 소음방지를 도모하게 하는 효과를 제공하게 되는 것이다.According to the above description, since the bubble trapping function in the expansion tank adds a strainer, the bubble inflow to the return outlet is relatively reduced, thereby reducing the amount of air sucked into the circulation pump. In addition to preventing the decrease in pump capacity, since the amount of air sucked into the heat exchanger is reduced, there is no boiling noise caused by the inflow of air, thereby providing an effect of preventing noise of the heat exchanger.
본 고안은 기재된 구체예에 대해서만 상세히 설명되었지만 본 고안의 사상과 범위 내에서 변형이나 변경할 수 있음은 본 고안이 속하는분야의 당업자에게는 명백한 것이며, 그러한 변형이나 변경은 첨부한 실용신안등록청구범위에 속한다 해야 할 것이다.Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that the present invention may be modified or changed within the spirit and scope of the present invention, and such modifications or changes are within the scope of the appended claims. You will have to.
