본 발명은 보일러의 압력도피장치에 관한 것으로서, 보다 상세하게는 듀얼타입 가스보일러의 주열교환기에 잔존하는 열에 의한 직수유입관 및/또는 온수공급관의 압력의 증가를 팽창탱크로 도피시킬 수 있는 가스보일러의 압력도피장치에 관한 것이다.The present invention relates to a pressure evacuation device of a boiler, and more particularly, a gas boiler capable of escaping an increase in pressure of a direct inlet pipe and / or a hot water supply pipe due to heat remaining in a main heat exchanger of a dual type gas boiler to an expansion tank. To a pressure evacuation device.

주지하는 바와 같이 일반 가정이나 공공건물 등에 사용되는 보일러는 난방용이나 온수용으로 이용되고 있다. 이러한 보일러의 대부분은 기름 혹은 가스를 연료로 사용하여 버너를 통해 연소시킨 다음, 이 연소과정에서 발생하는 연소열을 이용하여 물을 가열하고, 이 가열된 물(온수)을 실내로 순환시켜 난방을 실시하거나 사용자의 필요에 따라 온수로 제공하게 된다.As is well known, boilers used in homes and public buildings are used for heating or hot water. Most of these boilers use oil or gas as fuel to combust through a burner, and then heat water using the combustion heat generated during the combustion process, and circulate the heated water (hot water) into a room to perform heating. Or hot water according to the user's needs.

이처럼 사용되는 연료에 따라 기름보일러와 가스보일러로 구분되는 보일러에 있어서, 특히, 가스보일러는 그 종류가 매우 다양하고, 설치 형태에 따라 여러 가지 타입으로 구분되고 있다.In the boilers divided into oil boilers and gas boilers according to the fuel used in this way, in particular, the gas boilers are very various types, and are divided into various types according to the installation form.

즉, 상기 가스보일러는 팽창탱크의 형식에 따라 밀폐식 가스보일러와 개방식 가스보일러로 구분할 수도 있고, 온수열교환기(일명, 급탕열교환기)의 설치형태에 따라 싱글타입 가스보일러와 듀얼타입 가스보일러로 구분할 수도 있다.That is, the gas boiler may be classified into an enclosed gas boiler and an open gas boiler according to the type of expansion tank, and may be divided into a single type gas boiler and a dual type gas boiler according to the installation type of the hot water heat exchanger (aka, hot water supply heat exchanger). You can also distinguish.

여기서, 도 1에 도시된 바와 같이, 듀얼타입 가스보일러란 온수열교환기가 주열교환기 파이프 안에 삽입 설치됨으로써, 주열교환기에서 난방 공급이 이루어지는 과정에서 온수열교환기 내에서 열교환이 이루어져 온수 공급이 가능하도록 된 가스보일러를 말한다.Here, as shown in Figure 1, the dual-type gas boiler is a hot water heat exchanger is inserted into the main heat exchanger pipe, the heat exchange is made in the hot water heat exchanger in the process of heating the supply in the main heat exchanger to enable hot water supply Say boiler.

이처럼 상기 듀얼타입 가스보일러는 온수열교환기가 주열교환기 안으로 삽입설치 됨으로써, 온수열교환기가 주열교환기와 분리 설치되는 싱글타입 열교환기에 비해 관련부품들의 일부 삭제가 가능하여 제품의 컴팩트(compact)화 및 원가 절감 차원에서 많은 비용의 절감을 이룰 수 있다는 장점을 갖는다.As such, the dual type gas boiler is installed with a hot water heat exchanger into the main heat exchanger, so that parts of the hot water heat exchanger can be partially removed compared to the single type heat exchanger in which the hot water heat exchanger is installed separately from the main heat exchanger, thereby making the product compact and reducing the cost. Has the advantage of achieving a lot of cost savings.

즉, 이러한 종래 듀얼타입 가스보일러의 구성을 살펴보면 다음과 같다.That is, the configuration of the conventional dual type gas boiler is as follows.

도 1에 도시된 바와 같이, 상기 듀얼타입 가스보일러(B)는 연소실(4)내부에서 가스공급관(1)을 통하여 유입된 가스를 연소시켜 연소열을 발생시킬 수 있도록 마련된 가스버너(2)와; 상기 가스버너(2)의 상부에 설치되어 가스버너(2)의 연소열을 받아 난방수를 가열하는 주열교환기(5)와; 사용자가 설정온도를 입력할 수 있음은 물론, 가스보일러(B)의 작동을 조작할 수 있고, 가스보일러(B)의 상태를 표시하는 기능을 갖는 상기 룸콘(30)과, 사용자가 조작하는 룸콘(30)의 입력신호를 받아 일련의 연소과정 및 가스보일러(B)의 작동을 제어하는 메인컨트롤러(20)를 갖추고 있다.As shown in FIG. 1, the dual type gas boiler B includes a gas burner 2 configured to generate combustion heat by combusting the gas introduced through the gas supply pipe 1 in the combustion chamber 4; A main heat exchanger 5 installed above the gas burner 2 to receive the combustion heat of the gas burner 2 and to heat the heating water; The user can input the set temperature, as well as the operation of the gas boiler (B), the room cone 30 having a function of displaying the state of the gas boiler (B), and the room cone operated by the user In response to the input signal of 30, a main controller 20 for controlling a series of combustion processes and operation of the gas boiler B is provided.

이때, 상기 가스버너(2)의 하부에는 연소를 촉진시키기 위해 공기를 공급하는 송풍기(18)가 마련되어 있고, 상기 가스버너(2)의 일 측면에는 가스버너(2)를 점화시키기 위한 점화플러그(3)가 마련되어 있으며, 상기 연소실(4)의 상부에는 일 련의 연소과정에서 발생된 연소가스를 배출하기 위해 마련된 배기구(7)가 마련되어 있다. 상기 송풍기(18)의 일측면에는 보일러의 공기비례제어를 위해 송풍기(18)로 유입되는 공기의 압력을 측정하는 풍압센서(21)가 마련되어 있다.At this time, the lower part of the gas burner (2) is provided with a blower (18) for supplying air to promote combustion, and on one side of the gas burner (2) an ignition plug for igniting the gas burner (2) ( 3) is provided, and the upper part of the combustion chamber (4) is provided with an exhaust port (7) provided for discharging the combustion gas generated in a series of combustion process. One side of the blower 18 is provided with a wind pressure sensor 21 for measuring the pressure of the air flowing into the blower 18 for proportional control of the boiler.

또한, 상기 주열교환기(5)로부터 가열된 난방수를 실내 난방을 위해 공급하기 위한 난방수공급관(10)이 주열교환기(5)에 연결되어 있고, 상기 보일러(B)에는 실내를 난방하고 환수되는 물(난방수)을 항상 일정량 유지하는 상태로 일시 저장하는 팽창탱크(16)가 난방환수관(17)상에 설치되어 있으며, 상기 팽창탱크(16)에 저장된 물을 물공급관(6)을 통해 주열교환기(5)로 공급하기 위한 순환펌프(15)가 마련되어 있다.In addition, a heating water supply pipe 10 for supplying heating water heated from the main heat exchanger 5 for indoor heating is connected to the main heat exchanger 5, and the boiler B is heated and returned to the room. An expansion tank 16 for temporarily storing water (heating water) in a state of constantly maintaining a predetermined amount is installed on the heating return pipe 17, and the water stored in the expansion tank 16 is transferred through the water supply pipe 6. The circulation pump 15 for supplying to the main heat exchanger 5 is provided.

특히, 상기 가스보일러(B)에는 사용자의 필요에 따라 온수를 공급할 수 있도록 요구되는 온수량의 증가에 따라 직수(냉수)를 공급하는 직수유입관(13)과, 상기 직수유입관(13)에 연결되어 유입되는 유량을 감지하는 감압유량흐름스위치(24)와, 상기 직수유입관(13)을 통해 유입된 물이 주열교환기(5)내에 설치된 온수열교환기(12)로 공급된 후 배출되는 온수공급관(14)이 마련되어 있다. In particular, the gas boiler (B) to the direct water inlet pipe 13 to supply direct water (cold water) in accordance with the increase in the amount of hot water required to supply hot water to the user's needs, and to the direct water inlet pipe (13) Depressurized flow rate switch (24) for detecting the flow rate is connected to the water supplied through the hot water inlet pipe 13, the hot water heat exchanger (12) installed in the main heat exchanger (5) and discharged hot water discharged The supply pipe 14 is provided.

그러나, 이러한 종래의 듀얼타입 가스보일러에 있어서, 난방 및 온수사용 후 주열교환기(5)에 있던 잔열에 의해 온수라인의 물, 즉 직수유입관(13) 및 온수공급관(14)의 물이 온도 상승에 의해 열팽창함으로써 발생한 압력이 다른 곳으로 도피하지 못하게 되어 직수유입관(13) 또는 온수공급관(14)이 파열되는 문제가 발생하였다. However, in such a conventional dual-type gas boiler, the water of the hot water line, that is, the water of the direct water inlet pipe 13 and the hot water supply pipe 14 rises due to the residual heat in the main heat exchanger 5 after the heating and hot water use. This prevents the pressure generated by thermal expansion from escaping to other places, causing the direct inflow pipe 13 or the hot water supply pipe 14 to rupture.

본 발명은 상술한 바와 같은 문제를 고려하여 안출된 것으로서, 본 발명의 목적은 듀얼타입 가스보일러의 직수유입관 또는 온수공급관에 안전밸브의 일단을 연결하고 타단을 팽창탱크와 연결함으로써, 잔열에 의한 직수유입관 또는 온수출구관의 압력에 따라 자동으로 개폐하여 압력을 팽창탱크로 도피시킬 수 있는 가스보일러의 압력도피장치를 제공하는 데 있다.  The present invention has been made in view of the above problems, an object of the present invention by connecting one end of the safety valve to the inlet pipe or hot water supply pipe of the dual-type gas boiler and the other end to the expansion tank, The present invention provides a pressure escape device for a gas boiler that can open and close automatically according to the pressure of a direct inflow pipe or a hot water outlet pipe to evacuate the pressure to an expansion tank.

상술한 바와 같은 본 발명의 목적은, 직수를 유입하는 직수유입관, 온수를 공급하는 온수공급관 및 난방환수관과 난방수출구관에 연결된 팽창탱크를 포함하는 온수 공급시스템을 갖춘 보일러에 있어서, 일단이 상기 직수유입관의 감압유량흐름스위치 후단 및 상기 온수공급관 중 적어도 하나에 연결되고 타단이 상기 팽창탱크에 연결됨으로써, 상기 직수유입관 또는 상기 온수공급관 내의 압력의 변화에 따라 개폐가 이루어져 상기 팽창탱크로 압력을 분배하는 안전밸브를 구비한 보일러의 압력도피장치에 의해 달성될 수 있다.An object of the present invention as described above, in the boiler having a hot water supply system including a direct water inflow pipe for introducing direct water, a hot water supply pipe for supplying hot water, and an expansion tank connected to a heating return pipe and a heating export pipe. Connected to at least one of the rear end of the depressurized flow rate switch of the direct inflow pipe and the hot water supply pipe, and the other end is connected to the expansion tank, opening and closing according to the change in the pressure in the direct water inflow pipe or the hot water supply pipe to the expansion tank. It can be achieved by a pressure escape device of a boiler with a safety valve for distributing pressure.

이하, 도 2를 참조하여 본 발명에 따른 압력도피장치를 설명한다. 도 2는 본 발명에 따른 압력도피장치가 장착된 상태를 개략적으로 보여주는 단면도이다. 도 2에 보인 바와 같이, 본 발명에 따른 압력도피장치는 종래의 듀얼타입 가스보일러의 구성을 기본적으로 채용한다. Hereinafter, a pressure escape apparatus according to the present invention will be described with reference to FIG. 2. 2 is a cross-sectional view schematically showing a state in which the pressure escape device according to the present invention is mounted. As shown in Fig. 2, the pressure escape apparatus according to the present invention basically adopts a configuration of a conventional dual type gas boiler.

본 발명은 듀얼타입 열교환기, 즉 가스보일러의 온수열교환기(12)를 주열교환기(5) 파이프 내에 삽입함으로써, 주열교환기(12)에서 난방 및 온수가 이루어지는 열교환기에 있어서, 난방 및 온수 사용 후 주열교환기(5)에 잔존하는 열(이하, 잔열이라 한다) 때문에 직수유입관(13) 및/또는 온수공급관(14) 내의 물이 열팽창함으로써, 직수유입관(13) 및/또는 온수공급관(14)을 파열시키는 문제점을 해결하고자, 도 2에 보인 바와 같이 안전밸브(11)를 직수유입관(13; 또는 온수공급관(14)) 및 팽창탱크(16)에 연결시키는 것을 특징으로 한다.
이때, 도 2에 도시된 바와 같이, 상기 직수유입관(13)과 팽창탱크(16) 사이에 안전밸브(11)를 연결 설치할 경우에는 감압유량흐름스위치(24)의 후단에 연결 설치하는 것이 바람직하다.
이는 사용자가 온수 사용 중 온수공급라인을 폐쇄할 경우 및 열교환기의 잔열에 의해서 발생되는 압력(상당히 큼)으로 인해 상기 온수공급관(14)과 직수유입관(13) 사이에 역압이 발생하게 될 때, 상기 감압유량흐름스위치(24)의 다이어프램에 역압이 작용하지 못하도록 상기 안전밸브(11)가 역압에 대응하여 개방됨으로써, 압력을 도피할 수 있도록 하는 구조를 제공하기 위함이다.
즉, 상기 직수유입관(13)에 설치된 감압유량흐름스위치(24)의 다이어프램에 역압이 반복적으로 작용할 경우에 다이어프램이 찢어짐이 발생하여 누수가 일어나는 문제점이 있기 때문에 이를 미연에 방지하기 위해 감압유량흐름스위치(24)의 후단에 안전밸브(11)를 설치하는 것이 바람직한 것이다.The present invention provides a dual type heat exchanger, that is, a hot water heat exchanger (12) of a gas boiler in a main heat exchanger (5) pipe, whereby the main heat exchanger (12) is heated and heated in a heat exchanger, wherein the main heat after heating and hot water is used. Due to the heat remaining in the exchanger 5 (hereinafter referred to as residual heat), the water in the direct water inflow pipe 13 and / or the hot water supply pipe 14 is thermally expanded, whereby the direct water inflow pipe 13 and / or the hot water supply pipe 14 In order to solve the problem of rupture, it is characterized in that the safety valve 11 is connected to the direct inlet pipe 13 (or hot water supply pipe 14) and the expansion tank 16 as shown in FIG.
At this time, as shown in Figure 2, when the safety valve 11 is connected between the direct inflow pipe 13 and the expansion tank 16 is preferably installed connected to the rear end of the reduced pressure flow flow switch (24). Do.
This is because when the user closes the hot water supply line while using hot water and when a back pressure is generated between the hot water supply pipe 14 and the direct water inlet pipe 13 due to the pressure (significantly large) generated by the residual heat of the heat exchanger. In order to prevent the pressure from acting on the diaphragm of the depressurized flow rate switch 24, the safety valve 11 is opened in response to the reverse pressure, thereby providing a structure to escape the pressure.
That is, when the reverse pressure acts repeatedly on the diaphragm of the depressurized flow flow switch 24 installed in the direct water inflow pipe 13, the diaphragm is torn and there is a problem in that water leakage occurs. It is preferable to provide the safety valve 11 at the rear end of the switch 24.

이하, 안전밸브(11)가 직수유입관(13)에 마련된 것으로 설명하였지만 안전밸브(11)는 온수공급관(14)에 마련되어도 된다. Hereinafter, although the safety valve 11 was demonstrated as provided in the direct inflow pipe 13, the safety valve 11 may be provided in the hot water supply pipe 14.

안전밸브에 대해 간단히 설명하면, 안전밸브(11)는 고압 및 저압가스를 매체로 운영되는 고압가스 제조설비, 석유 화학설비, 보일러등 모든 산업분야에 다양하게 이용되고 있는 것으로서, 설비의 각 구성부분에 이상압력이 발생되었을 경우 장치가 폭발한다던가 또는 균열이 발생될 염려를 사전에 방지하여 설비를 보호할 수 있도록 구성된 안전장치이다. Briefly describing the safety valve, the safety valve 11 is widely used in all industrial fields, such as a high-pressure gas manufacturing equipment, a petrochemical equipment, a boiler, which operates as a medium using high pressure and low pressure gas, and each component part of the equipment. This is a safety device configured to protect the equipment by preventing the possibility of explosion or cracking in case of abnormal pressure.

본 발명에 사용되는 안전밸브(11)는 도 3에 보인 바와 같이 공지된 것으로서, 일정압력 이상이 되면 자동으로 열려 유체나 기체를 통과시키고, 그 결과 장치 내의 압력이 낮아지면 스프링의 탄성력에 의해 자동으로 닫히는 구성을 취한다. 안전밸브의 자세한 구성에 대해서는 설명은 생략한다. The safety valve 11 used in the present invention is known as shown in Fig. 3, and automatically opens when a certain pressure or more is passed through the fluid or gas, and as a result, when the pressure in the device is lowered, it is automatically driven by the elastic force of the spring. Take a closed configuration. Detailed description of the safety valve is omitted.

우선, 도 3에 보인 바와 같이, 안전밸브(11)의 일단, 즉 직수연결관(29)이 직수유입관(13)에 연결된다. 다음, 안전밸브(11)의 타단, 즉 탱크연결관(19)이 난방수공급관(10) 및 난방환수관(17)이 연결된 팽창탱크(16)에 연결된다. First, as shown in FIG. 3, one end of the safety valve 11, that is, the direct connection pipe 29, is connected to the direct inflow pipe 13. Next, the other end of the safety valve 11, that is, the tank connecting pipe 19 is connected to the expansion tank 16 to which the heating water supply pipe 10 and the heating return pipe 17 are connected.

그 결과, 주열교환기(5)의 잔열에 의해 직수유입관(13) 내의 물이 기설정된 압력(안전밸브 상의 압력조정나사로 압력을 기설정할 수 있다)보다 높아지는 경우 안전밸브(11)의 작용에 의해 팽창된 물이 탱크연결관(19)을 따라 팽창탱크(16)로 이동함으로써, 열팽창에 의해 높아진 압력이 다시 낮아지게 된다. As a result, when the water in the direct inflow pipe 13 becomes higher than the preset pressure (the pressure can be preset with the pressure adjusting screw on the safety valve) due to the residual heat of the main heat exchanger 5, the action of the safety valve 11 As the expanded water moves along the tank connecting pipe 19 to the expansion tank 16, the pressure increased by thermal expansion is lowered again.

그 후, 안전밸브(11)는 직수유입관(13) 내의 물의 낮아진 압력 및 스프링의 탄성작용에 의해 자동으로 닫히게 됨으로써, 더 이상 직수유입관(13)으로부터 팽창탱크(16)로 물이 이동될 수 없게 된다. Thereafter, the safety valve 11 is automatically closed by the reduced pressure of the water in the water inlet pipe 13 and the elastic action of the spring, so that water can no longer be moved from the water inlet pipe 13 to the expansion tank 16. It becomes impossible.

따라서, 압력의 증가로 인한 직수유입관(13) 및 온수공급관(14)의 파열을 방지할 수 있다. Therefore, it is possible to prevent the rupture of the direct inflow pipe 13 and the hot water supply pipe 14 due to the increase in pressure.

이상에서 설명한 본 발명에 따른 보일러의 압력도피장치는 당업자의 입장에서 설계의 변형, 변경이 가능하다. Pressure evacuation apparatus of the boiler according to the present invention described above can be modified, modified in the design of the skilled person.

상술한 바와 같이, 본 발명에 따른 보일러의 압력도피장치는 보일러의 직수유입관의 감압유량흐름스위치 후단 및 온수공급관 중 적어도 하나에 안전밸브의 일단을 연결하고 타단을 팽창탱크에 연결함으로써, 주열교환기의 잔열에 의한 직수유입관 및/또는 온수공급관 내의 압력을 증가를 효과적으로 팽창탱크로 도피시킬 수 있다. As described above, the pressure escape device of the boiler according to the present invention by connecting one end of the safety valve to at least one of the rear end of the reduced pressure flow flow switch and the hot water supply pipe of the water inlet pipe of the boiler and the other end to the expansion tank, The pressure in the direct inflow pipe and / or the hot water supply pipe due to the residual heat of can be effectively escaped to the expansion tank.
