본 고안은 가정용으로 사용되는 온수보일러에 관한 것으로, 특히 보일러의 내압이 일정압 이상으로 올라가면 내압 자동조절장치에 의해 보일러의 내압이 자동으로 조절될 수 있도럭한 온수보일러에 대한 것이다.The present invention relates to a hot water boiler for home use, in particular, to a hot water boiler that can be automatically adjusted to the internal pressure of the boiler by the automatic pressure adjusting device when the internal pressure of the boiler rises above a certain pressure.

일반적으로 온수를 순환시켜 난방을 실시하는 시스템에서는 보일러 동체 내부에 설치되어 있는 가열실(열교환기)내의 물을 기름이나 가스등의 열원으로 이용 가열시킴으로써 고온으로 가열된 난방수가 난방배관(난방부하부)을 순환하면서 난방이 이루어지도록 하고 있는바, 이와 같은 난방장치에 있어서는 반드시 순환하는 난방수를 보충(난방수의 자연증발 및 압력 팽창으로 배출된 난방수의 보충)해 줄수 있는 난방수 보충장치가 필요하게 되고, 동시에 가열실내의 압력조절을 위해 팽창압력을 완충시켜 줄 수 있는 장치가 요구된다.In general, in a system that circulates hot water and performs heating, heating water heated to a high temperature by heating water in a heating chamber (heat exchanger) installed inside a boiler fuselage as a heat source such as oil or gas (heating load) In order to make sure that the heating is done while circulating, the heating water refilling device must be replenished (refilling the heating water discharged by the natural evaporation of the heating water and the pressure expansion). At the same time, there is a need for a device that can buffer the expansion pressure for pressure control in the heating chamber.

그러므로, 종래에는 이를 해결하기 위해 보일러와는 별도로 즉, 보일러 동체 외부에 불탑등을 이용한 보충수통(팽창탱크)을 높게 설치하고 이를 난방수 귀환관에 연결시켜 자연 감소되는 난방수를 보충토록 함과 동시에 제1도의 예시와 같이 난방수의 출력라인에 팽창관을 분기하여 팽창압력이 이 팽창관을 통해 보충수통으로 출력되도록 하며 난방수의 냉각으로 가열실내압이 떨어질 때 부족되는 난방수를 외부의 보충수통으로 부터 별도의 보충수관을 통해 부족분의 난방수를 보충받도록 하는 방식을 채택 사용하여 왔었다.Therefore, in order to solve this problem, in order to solve this problem, a supplementary water tank (expansion tank) using a pylon or the like is installed outside the boiler body and connected to a heating water return pipe to supplement the naturally reduced heating water. At the same time, as shown in FIG. 1, the expansion pipe is branched to the output line of the heating water so that the expansion pressure is output through the expansion pipe to the replenishing water bottle. When the internal pressure of the heating room drops due to the cooling of the heating water, It has been used to make up for the shortage of heating water through a supplementary canister from the canister.

그러나, 이와 같이 보충수통을 보일러외부에 설치하는 방식을 이를 설치하기 위한 별도의 설치공간과 자연적이 수두압의 발생토록 일정한 높이(보일러 보다 높게)가 필요하게 내부에서 발생하는 이물질의 침전 및 외부로 부터의 먼지유입으로 보충수 유입관의 막힘과 볼탑의 잦은 고장등으로 보일러실이 침수되거나 전자기기 및 정밀 모터등이 부착된 보일러에 치명적인 피해를 입히게 되는등의 문제가 있었다.However, in this way, the supplementary water tank can be installed outside of the boiler, and a separate installation space for installing it and a certain height (higher than the boiler) are needed to naturally generate water head pressure. As a result of the dust inflow, there was a problem of flooding the boiler room due to the blockage of the supplementary water inlet pipe and frequent failure of the ball tower, or causing a fatal damage to the boiler with the electronic equipment and the precision motor.

본 고안은 상기와 같은 존래의 온수보일러가 갖는 제방 문제점을 감안하여 대기 개방형 보충수통을 보일러 동체 내부에 설치하여 보일러 설치작업의 편의성 및 안전성을 도모함과 동시에 내압자동 조절장치에 의한 가열실 내부의 압력조절(난방수의 팽창 및 보충)이 하나의 팽창관을 통해 자동적으로 실현되도록 안출한 것으로, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention, in consideration of the problems of the existing hot water boilers as described above, by installing an atmospheric open supplementary water tank inside the boiler body to improve the convenience and safety of the boiler installation work and at the same time the pressure inside the heating chamber by the pressure-resistant automatic control device Control (expansion and replenishment of heating water) is designed to be realized automatically through one expansion tube, which will be described in detail based on the accompanying drawings.

난방기능과 급탕기능을 갖는 온수보일러를 구성함에 있어서, 보일러 동체(1) 내부에 가열실(2) 가열실은 통상 난방수가 충만 수장되는 수실과 연소화염의 이동로인 연소실로 구성됨)과 연결되는 보충수통(3)을 설치하되 일정압에 의한 개폐동작이 이루어지는 내압자동 조절변(13)을 상기 보충수통(3)과 연결시켜 수실내의 수압 완충 및 보충기능을 수행토록 하고, 급탕입수관(6)에 전자변(8)이 설치된 난방수 보충관(10)을 분기하여 내압 자동조절장치의 보충수통(3)에 설치된 저수위감지기(9)의 감지작동에 따라 가열실(2) 내부로 난방수의 자동급수가 이루어지도록 한 것으로, 보충수통(3)은 팽창관(4)을 통하여 가열실(2)에 설치된 내압자동 조절변(13)과 연결되는데, 이 팽창관(4)은 제4도의 예시와 같이 끝단이 보충수통(3)내의 물속에 잠기도록 깊게 설치된다.In constructing a hot water boiler having a heating function and a hot water supply function, a heating chamber (2) heating chamber inside the boiler body (1) is usually connected to a water chamber filled with heating water and a combustion chamber which is a moving path of combustion flame. Installing a water bottle (3) but connecting the pressure-resistant automatic control valve (13), the opening and closing operation by a constant pressure to the replenishing water tank (3) to perform the water pressure buffer and replenishment function in the chamber, the hot water inlet pipe (6 Branching of the heating water supplement pipe (10) with the electronic valve (8) is installed in the heating chamber (2) in accordance with the detection operation of the low water level sensor (9) installed in the supplementary water container (3) of the automatic pressure regulating device The automatic water supply is to be made, the replenishing water tank 3 is connected to the pressure-resistant automatic control valve 13 installed in the heating chamber 2 through the expansion pipe (4), the expansion pipe (4) is an example of FIG. The end is deeply installed so that the end is submerged in the water in the refill bottle (3).

상기 내압자동조절변(13)은 2중밸브로 구성되어 양방향으로 유체를 통과시킬 수 있도록 한 통상의 압력조절 밸브로써 일측 밸브의 열리는 압력이 타측 밸브의 열리는 압력보다 더 높게 설정되어 있다. 그러므로 수실 내부압력은 일정압(대기압 이상 1kg/㎠ 이하, 즉, 0.075-kg/㎠의 압력) 이상이 되어야 보통구통(3)으로 증가분의 물이 출력되며, 반대로 수실 내부압력이 대기압 이하로 내려가면 보충수통(3)내의 물이 역으로 수실로 유입되게 된다.The automatic pressure regulating valve 13 is configured as a double valve to allow fluid to pass in both directions. The opening pressure of one valve is set higher than the opening pressure of the other valve. Therefore, the internal pressure of the chamber should be above a certain pressure (1kg / cm2 or more above atmospheric pressure, ie, 0.075-kg / cm2 or more) to increase the water output to the common cylinder (3). The water in the supplemental water can (3) is introduced into the water chamber in reverse.

도면중 미설명 부호, 14는 온도센서, 15는 CTC 콘트롤장치, 16은 급기구, 17은 오버플로우 구멍이다.In the figure, reference numeral 14 denotes a temperature sensor, 15 denotes a CTC control device, 16 denotes an air supply port, and 17 denotes an overflow hole.

이와 같이 구성되는 본 고안의 작용효과를 설명하면, 보일러 동체(1)내에 설치되어 있는 수실과 연소실로 이루어진 가열실(2)이 가열되면서 수실내에 있는 물이 충만되어 난방출수관(5)를 통하여 순환을 하면서 난방이 실시되고, 급탕입수관(6)을 통하여 유입된 차거운 물이 수실내부를 지나면서 가열되어 급탕출수관(7)을 통하여 급탕수로 이용되는 과정은 통상의 보일러 기능과 같다.Referring to the effect of the present invention configured as described above, while the heating chamber (2) consisting of the water chamber and the combustion chamber installed in the boiler body (1) is heated, the water in the water chamber is filled with the heating outlet pipe (5) The heating is performed while circulating, and the cold water introduced through the hot water inlet pipe 6 is heated as it passes through the inside of the water chamber and used as the hot water through the hot water spout pipe 7 as in the normal boiler function. .

그런데, 이와 같은 난방기능을 수행함에 있어서, 수실내에는 난방순환에 필요한 물이 항시 충만되어 있어야 함은 물론이고, 가열실의 가열에 따른 가열실 내부 압력조절이 이루어져야 하는바, 본 고안에는 이같은 두가지 기능이 보일러 동체(1) 내부에 설치되는 팽창관(4)으로 연결된 내압자동조절변(13)과 보충수통(3)으로 구성되는 내압 자동조절장치 및 급탕입수관(6)에서 분기된 난방수보충관(10)과 이 난방수보충관(10)에 설치된 전자변(8)에 의해서 자동 실행되는 것이다.By the way, in performing the heating function, the water chamber should be always filled with water required for the heating circulation, as well as the pressure inside the heating chamber should be adjusted according to the heating of the heating chamber, the present two Automatic water pressure regulating device consisting of a pressure-resistant automatic control valve (13) connected to an expansion pipe (4) installed inside the boiler fuselage (1) and a replenishing water tank (3) and a heating water branched from a hot water supply pipe (6). It is automatically executed by the supplementary pipe 10 and the electromagnetic valve 8 installed in the heating water supplement pipe 10.

즉, 보일러의 가열실(2)이 고온 가열되어 수실내의 수압(압력)이 대기압 이상 kg/㎠의 일정압 이상 상승하게 되면 내압자동조절변(13)이 열리면서(개로)이를 통하여 팽창 증가된 물이 출력되어 팽창관(4)을 거쳐 보일러 동체(1)내에 설치된 대기 개방형의 보충수통(3)으로 배출되므로써 수실내의 팽창된 수압조절이 이루어지는 것이며, 한편, 버어너의 가동이 증지되고 가열실(2)을 구성하는 수실로 환수되는 냉각된 난방귀환수의 영향으로 수실내의 난방수 온도가 떨어지게 되면 하강된 온도만큼 수실 내부압력이 떨어지게 되므로 가열실(2) 내부 압력이 대기압보다 낮아져 대기압력에 의해 보충수통(3)내의 물이 팽창관(4)을 통하여 다시 수실내로 역유입 되므로써 난방수의 보충이 자동적으로 이루어지는 것이다.That is, when the heating chamber 2 of the boiler is heated at a high temperature so that the water pressure (pressure) in the chamber rises above a certain pressure of kg / cm 2 or more, the internal pressure automatic control valve 13 opens (opening) and expands therethrough. The water is output and discharged through the expansion pipe (4) to the atmospheric open type supplementary water tank (3) installed in the boiler body (1) to control the expansion of the hydraulic pressure in the chamber, while the operation of the burner is vaporized and heated. When the temperature of the heating water in the chamber drops due to the influence of the cooled heating return water returned to the chamber constituting the chamber 2, the internal pressure of the chamber drops as much as the lowered temperature, so the pressure inside the heating chamber 2 becomes lower than the atmospheric pressure. The pressure of the water in the replenishing can 3 is flowed back into the water chamber through the expansion pipe 4 and the replenishment of the heating water is automatically performed.

즉, 수실압력이 낮아지게 되면 내압자동조절변(13)을 통하여 보충수통(3)으로 나가는 출력은 차단되고 수실로 들어오는 입력은 열려 있는 상태가 되므로 수실 내부압력이 대기압과 같아질때까지 보충수통(3)내의 물이 수실로 역유입 되게 되는 것이다. 이러한 난방수의 팽창 및 보충동작이 하나의 팽창관(4)을 통해 반복 수행되면서 수실 내부압이 일정하게 조절이 되면서 난방수의 원활한 순환이 실행되는 것이다.That is, when the chamber pressure decreases, the output to the make-up container 3 through the automatic pressure regulating valve 13 is cut off, and the input to the chamber becomes open, so that the make-up water can be kept until the internal pressure of the chamber becomes equal to atmospheric pressure. 3) The water in the water will flow back into the chamber. As the expansion and replenishment of the heating water is repeatedly performed through one expansion tube 4, the internal pressure of the chamber is constantly adjusted, and thus the smooth circulation of the heating water is performed.

여기서 보충수통(3)내의 물이 자연 증발하거나 기타요인(누수등)으로 인하여 보충수통(3)에 설치된 저수위 감지기(9) 밑으로 떨어지게 되면, 즉, 저수위선 아래로 내려가게 되면 저수위감지기(9)가 동작하여 난방수보충관(10)에 설치된 전자변(8)을 개로시켜 급탕입수관(6)으로 유입되는 물이 이 난방수보충관(10)을 통하여 가열실(2)내 수실로 유입되도록 함으로써 부족한 난방수를 적정수위까지 보충하게 되는 것이다. (전자변(8)은 일방향성 밸브로 난방수가 적정수위까지 보충되면 저수위감지기(9)의 감지작동에 의해 자동 '오프'됨).Here, if the water in the replenishing can (3) falls below the low level sensor (9) installed in the replenishing can (3) due to natural evaporation or other factors (leakage, etc.), that is, if the water goes down below the low level line (9) ) Is opened to open the electronic valve 8 installed in the heating water supplement pipe 10, and the water flowing into the hot water inlet pipe 6 flows into the water chamber in the heating chamber 2 through the heating water supplement pipe 10. By doing so, the insufficient heating water is replenished to the appropriate level. (The solenoid valve 8 is a one-way valve that is automatically 'off' by the sensing operation of the low water level detector 9 when the heating water is replenished to an appropriate level.)

이와 같이 본 고안은 대기 개방형 보충수통(3)을 보일러 동체(1) 내부로 설치하되 가열실(2)의 상부에 팽창한(4)과 연결되는 내압자동조절변(13)을 설치하여 수실내의 수압 완출조절이 하나의 팽창관(4)을 통해 자동으로 이루어지도록 하여 항시 원활한 난방수의 순환이 이루어지도록 함과 동시에 사용중 부족되는 난방수가 저수위 감지기(9)의 감지동작과 전자변(8)의 개폐동작으로 난방수의 자동 급수가 이루어지도록 하는등 보일러의 운전 효율을 증진시키고, 보일러의 설치 및 배관작업을 용이토록 하며, 난방수의 오염방지 효과와 안전성을 제고시킨 그 실사용 효과가 일층 고양된 신규의 고안이다.In this way, the present invention is installed in the boiler body (1) to open the atmosphere open-type replenishing can (3) inside the chamber by installing the pressure-resistant automatic control valve (13) connected to the inflated (4) in the upper portion of the heating chamber (2) Water pressure release control is automatically made through a single expansion tube (4) to ensure a smooth circulation of the heating water at all times and at the same time the heating water is insufficient during the detection operation of the low water level detector (9) and the electronic valve (8) Enhance the operation efficiency of the boiler by automatically opening and closing the heating water by opening and closing operation, facilitating the installation and piping work of the boiler, and the practical use effect that improves the pollution prevention effect and safety of the heating water. It is a novel design.
