Abstract

본 발명은 증기 가열관의 압력변화에 따라 자동으로 강제순환이 가능하게 구성된 증기 순환용 개폐장치에 관한 것이다.The present invention relates to a steam circulation switchgear configured to automatically force forced circulation in accordance with the pressure change of the steam heating tube.

종래에는 2개의 체크밸브형의 펌프가 있기는 하였으나 동시 작동이 불가능한 문제점이 많았다. 특히 체크밸브는 내부에 복잡한 부품들로 구성되어 있어 고장발생율이 높고, 만일 환수되는 쪽의 체크밸브가 고장을 일으키게 되면 내부의 압이 높아져 폭발 위험이 있었다. 또 전기를 동력으로 한 온수를 순환시키는 순환펌프 등이 있기는 하나 이는 액상의 유체만 순환이 가능할 뿐 증기를 순환시키는 일은 불가능한 폐단이 있었다.Conventionally, although there were two check valve type pumps, there were many problems that simultaneous operation was impossible. In particular, the check valve is composed of complex parts inside the high failure rate, if the check valve on the return side causes a high internal pressure, there was a risk of explosion. In addition, there is a circulation pump for circulating hot water powered by electricity, but it is possible to circulate only liquid fluid, but it is impossible to circulate steam.

본 발명은 증기 가열관의 압력변화에 따라 자동으로 강제순환이 가능하게 구성된 증기 순환용 개폐장치에 관한 것으로, 더욱 상세하게는 증기환수가열관내에서 증기압이 발생하면 그 압력에 의하여 개폐변이 승하강 작동하면서 일방으로 증기가 강제 자동 순환할 수 있도록 구성한 것이다.The present invention relates to a steam circulation switchgear configured to automatically force forced circulation according to the pressure change of the steam heating tube, and more particularly, when the steam pressure is generated in the steam return tube, the opening and closing valve is moved up and down by the pressure. While the steam is forced to circulate to one side is configured.

종래에도 이와 비슷한 목적으로 구성된 2개의 체크밸브형의 펌프가 있기는 하였으나 동시 작동이 불가능한 문제점이 많았다. 특히 체크밸브는 내부에 복잡한 부품들로 구성되어 있어 고장발생율이 높고 만일 환수되는 쪽의 체크밸브가 고장을 일으키게 되면 내부의 압이 높아져 폭발하게 되는 위험이 있었다.Conventionally, although there were two check valve type pumps configured for a similar purpose, there were many problems that simultaneous operation was impossible. In particular, the check valve is composed of complex parts inside the high failure rate and if the check valve on the return side causes a high internal pressure there is a risk of explosion.

또 전기를 동력으로 한 온수를 순환시키는 순환펌프 등이 있기는 하나 이는 액상의 유체만 순환이 가능할 뿐 증기를 순환시키는 일은 불가능할 뿐만 아니라 소비전력이 높아 운전비용이 많이 소요되는 폐단이 있었다.In addition, there are circulating pumps for circulating hot water powered by electricity, but it is possible to circulate only liquid fluid, not to circulate steam, and to have a high end of operation cost due to high power consumption.

본 발명은 이러한 문제점들이 완전히 해결된 증기압에 의하여 자동개폐작용이 가능하고 압력의 변화에 의해 강제 순환이 원활하게 이루어질 수 있도록 하는데 그 목적이 있다.The object of the present invention is to enable the automatic opening and closing action by the vapor pressure is completely solved these problems, and to ensure that the forced circulation is made smoothly by the change in pressure.

상기 목적을 달성하기 위한 본 발명은 내부가 중공인 통체(1)의 상단에 급배수주입구(2)를 형성하고 그 측면에는 공지의 증기환수가열관(4)과 연결된 온수공급구(3)를 형성하고, 하부에는 회수되는 증기환수가열관(4)과 연결되어 통체(1)의 하부를 통해 상기 급배수주입구(2)내로 연장된 환수구(4)를 설치하며, 상기 환수구(5)와 급배수주입구(2)의 사이에는 개폐변(6)이 설치되며, 상기 개폐변(6)은 환수구(5)의 상단에 씌워지고 그 상단 둘레에는 승강시 개방되고 하강시 닫혀지는 다수개의 환수공(8)을 포함하고 하단 둘레에는 급배수주입구(2)보다 지름이 크게 형성되어 급배수주입구(2)를 개폐하는 개폐플랜지(7)를 구성하여서 달성된다.The present invention for achieving the above object is to form a water supply and drain inlet (2) on the upper end of the hollow cylinder (1) inside the hot water supply port (3) connected to the known steam return pipe (4) It is formed, the lower part is connected to the recovered steam return heat pipe (4) to install a return port (4) extending into the water supply and drain inlet (2) through the lower portion of the cylinder (1), the return port (5) Opening and closing side 6 is installed between the water supply and drainage inlet (2), the opening and closing side (6) is covered on the upper end of the water inlet (5) and open around the upper end of the lift and closed when descending a plurality of It includes a return hole (8) and the bottom circumference is formed to have a larger diameter than the water supply and drainage inlet (2) is achieved by configuring the opening and closing flange (7) for opening and closing the water supply and drainage inlet (2).

이하, 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 외형 예시도이고, 도 2는 본 발명에 따른 유체의 공급시개폐장치 상태도이며, 도 3은 본 발명에 따른 증기의 배출시 개폐장치 상태도이다.Figure 1 is an exemplary view of the appearance of the present invention, Figure 2 is a state diagram of the opening and closing device for supplying fluid according to the present invention, Figure 3 is a state diagram of the opening and closing device when discharging steam according to the present invention.

도 1에 도시된 바와 같이 상하부가 막힌 원통형의 통체(1)의 상부에 급배수 주입구(2)가 형성되고 측면에는 온수공급구(3)가 형성되어 있고, 하부에는 환수구 (5)가 형성되어 있다.As shown in FIG. 1, a water supply and drainage port 2 is formed at an upper portion of a cylindrical cylinder 1 having an upper and a lower portion blocked, and a hot water supply port 3 is formed at a side thereof, and a return hole 5 is formed at a lower portion thereof. It is.

급배수주입구(2)는 서로 연통되어 있으며, 환수구(5)는 상단이 급배수 주입구(2) 내로 연장되어 있다.The water supply and drainage inlets 2 communicate with each other, and the return port 5 has an upper end extending into the water supply and drainage inlet 2.

또 온수공급구(3)와 환수구(5)에는 공지의 증기환수가열관(4)이 서로 연결되어 있다.In addition, a well-known steam return heat pipe 4 is connected to the hot water supply port 3 and the return port 5.

또한 통체(1)의 내부 즉, 환수구(5)와 급배수 주입구(2)의 사이에는 개폐변 (6)이 설치되어 있다. 이 개폐변(6)은 캡형태로 형성되어 환수구(5)의 상단에 씌워지고, 그 상단 둘레에는 다수개의 환수공(8)이 천공되어 있고, 하단 둘레에는 급배수주입구(2)보다 지름이 큰 개폐플랜지(7)가 형성되어 있다. 특히 개폐변(6)이 승강하게 되면 개폐플랜지(7)는 급배수주입구(2)를 닫고 환수공(8)은 개방되며, 하강시에는 개폐플랜지(7)는 급배수주입구(2)를 개방하고 환수공(8)은 닫혀지게 되어 있다.Moreover, the opening / closing edge 6 is provided in the inside of the cylinder 1, ie, between the return port 5 and the water supply and drain port 2. The opening / closing edge 6 is formed in a cap shape and is covered on the upper end of the return port 5, and a plurality of return holes 8 are perforated around the upper end thereof, and a diameter smaller than that of the water supply and drainage inlet 2 is provided on the lower end perimeter. This large opening and closing flange 7 is formed. In particular, when the opening and closing edge (6) is elevated, the opening and closing flange (7) closes the water supply and drainage inlet (2), the return hole (8) is open, the lowering opening and closing flange (7) to open the water supply and drainage inlet (2) The return hole 8 is to be closed.

이러한 구조에 의해 증기환수가열관(4)속에서 증기압이 발생하면 그 증기압은 증기환수가열관(4)내에서 전후방향으로 작용한다. 이때 증기압은 개폐변(6)의 개폐플랜지(7) 저면과 환수구(5)에 씌워진 개폐변(6) 내부에 작용하게 되므로 개폐변(6)은 자연히 상부로 승강한다. 이 작용에 의해 급배수주입구(2)는 개폐플랜지 (7)에 의해 차단되어 유입되는 유체의 순환은 정지되고, 환수구는 환수공(8)에 의해 개방되어 증기는 배출된다. 물론 증기가 아니라 액체상태의 유체라 하더라도 마찬가지이다.With this structure, when steam pressure is generated in the steam return heat tube 4, the steam pressure acts in the front and rear direction in the steam return heat tube 4. At this time, since the steam pressure acts on the bottom of the opening / closing flange 7 of the opening / closing edge 6 and the opening / closing edge 6 covered by the return port 5, the opening / closing edge 6 naturally moves upward. By this action, the water supply and drainage inlet 2 is blocked by the opening / closing flange 7 to stop the circulation of the inflowing fluid, and the return opening is opened by the return hole 8 so that steam is discharged. Of course, this is true even for liquid fluids, not vapors.

또한 증기환수가열관(4)의 내부에 증기압이 떨어지게 되면 도 2와 같이 개폐변으로 작용하는 유체의 압에 의해 다시 개폐변(6)은 하강하게 된다. 이 작동에 의해 급배수주입구(2)는 개방되어 유체는 통체(2)를 통해 증기환수가열관(4)으로 흐르게 되며 반대로 환수관(5)은 닫히게 되어 증기는 배출되지 않게 되어 유체의 배출 흐름은 발생되지 않는다.In addition, when the steam pressure falls inside the steam return heat pipe 4, the opening and closing valve 6 is lowered again by the pressure of the fluid acting as the opening and closing valve as shown in FIG. By this operation, the water supply / exhaust inlet 2 is opened so that the fluid flows through the tubular body 2 to the steam return pipe 4, on the contrary, the return pipe 5 is closed so that the steam is not discharged. Does not occur.

이러한 작동은 증기환수가열관(4)내에 압이 발생하게 되면 자동 연속적으로 발생하게 하므로 유체는 한 방향으로 계속 강제 순환하게 되는 것이다.This operation causes the steam return in the heat pipe (4) to automatically generate continuously because the fluid is forced to continue to circulate in one direction.
