Description

가스보일러용 팽창탱크Expansion tank for gas boiler
본 발명은 가스보일러용 팽창탱크에 관한 것으로서, 더욱 상세하게는 내부 구조가 간단하게 이루어져 제작이 용이하고 원가를 절감할 수 있을 뿐만 아니라 난방수의 압력 변화에 대한 내압성 및 내부식성을 구비한 가스보일러용 팽창탱크에 관한 것이다.The present invention relates to an expansion tank for a gas boiler, and more particularly, the internal structure is simple, making it easy to manufacture and reducing costs, as well as a gas boiler having pressure resistance and corrosion resistance to pressure changes of heating water. It relates to an expansion tank.
일반적으로 가스보일러에는 대기개방형 가스보일러와 대기차단형 가스보일러가 있다. 대기개방형 가스보일러는 팽창탱크 내의 난방수가 대기에 개방된 구조로 이루어진 것이고, 대기차단형 가스보일러는 팽창탱크 내의 난방수가 대기와 차단된 구조로 이루어진 것이다.In general, gas boilers include an atmospheric open gas boiler and an atmospheric shutoff gas boiler. The atmospheric open gas boiler is made of a structure in which the heating water in the expansion tank is open to the atmosphere, and the atmospheric blocking gas boiler is made of a structure in which the heating water in the expansion tank is blocked from the atmosphere.
도 1은 종래의 개방형 팽창탱크를 구비한 가스보일러의 구성을 보여주는 개략도이다.1 is a schematic view showing the configuration of a gas boiler equipped with a conventional open expansion tank.
대기개방형 가스보일러에는, 난방수를 순환시키는 순환펌프(10), 상기 순환펌프(10)에 의해 압송된 난방수에 버너(21)의 열에너지를 전달하기 위한 주열교환기(20), 난방가동시에는 난방배관(난방소요처)으로 난방수를 공급하고 온수사용시에는 온수열교환기(40) 측으로 난방수를 공급하는 삼방변(30), 온수사용시 직수를 가열시켜 온수를 공급하는 온수열교환기(40), 난방환수가 내부에 저장되고 난방수의 온도변화에 따른 압력변화를 흡수하기 위한 팽창탱크(50)가 구비된다.In the atmospheric open gas boiler, the circulation pump 10 for circulating the heating water, the main heat exchanger 20 for transferring the heat energy of the burner 21 to the heating water pumped by the circulation pump 10, heating at the time of heating operation Three-way valve (30) for supplying heating water to the pipe (heating point) and supplying the heating water to the hot water heat exchanger (40) when using hot water, hot water heat exchanger (40) for supplying hot water by heating direct water when using hot water, The heating return is stored therein and is provided with an expansion tank 50 for absorbing the pressure change according to the temperature change of the heating water.
미설명부호 61은 난방수 공급관, 62는 난방수 환수관, 63은 직수관, 64는 온수관이다. Reference numeral 61 denotes a heating water supply pipe, 62 a heating water return pipe, 63 a direct water pipe, and 64 a hot water pipe.
상기 개방형 팽창탱크(50)는 그 내부의 난방수가 정해진 수위 범위 내에 있는지 여부를 감지하기 위한 수위감지센서(51)가 설치되고, 상부 일측에는 내부의 난방수가 일정 수위를 초과하는 경우 외부로 흘러 넘치도록 오버플로우관(52)이 형성되어 있어 난방수가 대기에 개방된 구조로 되어 있다.The open type expansion tank 50 is provided with a water level sensor 51 for detecting whether the heating water in the inside of the predetermined level range, the upper one side overflows to the outside when the heating water exceeds a certain level An overflow pipe 52 is formed so that the heating water is open to the atmosphere.
이와 같은 대기개방형 가스보일러는, 구조가 간단하여 제작이 용이하고, 제조 비용이 저가인 장점이 있으나, 난방수 순환계가 대기에 개방되어 있어 보일러의 난방배관(난방소요처)보다 낮은 곳에 설치하지 못하므로 설치 위치상의 제약이 따르는 문제점이 있으며, 또한 난방수가 공기에 노출되어 있어 팽창탱크(50) 내부로 산소가 유입되므로 난방배관 내에 부식이 발생할 우려가 있는 단점이 있다.Such an open air gas boiler has advantages in that its structure is simple and easy to manufacture, and its manufacturing cost is low. However, since the heating water circulation system is open to the atmosphere, it cannot be installed below the boiler's heating piping (heating requirements). Therefore, there is a problem in that the installation position is limited, and since the heating water is exposed to the air, oxygen is introduced into the expansion tank 50, which may cause corrosion in the heating pipe.
도 2는 종래의 밀폐형 팽창탱크를 구비한 가스보일러의 구성을 보여주는 개략도이다.Figure 2 is a schematic diagram showing the configuration of a gas boiler with a conventional hermetic expansion tank.
대기차단형 가스보일러에는, 순환펌프(10), 주열교환기(20), 버너(21), 삼방변(30), 온수열교환기(40)가 구비된 점에서는 대기개방형 가스보일러와 기본적으로 동일하지만, 팽창탱크(70)가 대기와 차단된 밀폐형이라는 점과, 기수분리기(71), 과압안전변(72), 압력계(73)가 추가로 설치된 점에서 대기개방형과 구별된다.Atmospheric cut-off gas boiler is basically the same as the atmospheric open gas boiler in that the circulation pump 10, the main heat exchanger 20, the burner 21, the three-way valve 30, the hot water heat exchanger 40 is provided. , The expansion tank 70 is distinguished from the atmosphere open type in that the sealed type is isolated from the atmosphere, and the separator (71), the overpressure safety valve (72), the pressure gauge (73) is further installed.
상기 팽창탱크(70)는 외부 공기와 차단된 밀폐형 구조로서, 내부에는 고무판(70a)이 설치되고, 상기 고무판(70a)을 사이에 두고 기체(일례로, 질소)가 내부에 충진된 기체저장부(70b)와 난방수가 수용되는 난방수저장부(70c)가 형성되어 있다. 상기 고무판(70a)은 작용하는 압력에 따라 변형됨으로써 난방수의 압력변화를 흡수하도록 되어 있다.The expansion tank 70 is a sealed structure that is blocked from the outside air, a rubber plate (70a) is installed inside, the gas storage unit filled with a gas (for example, nitrogen) therebetween with the rubber plate (70a) in between. 70b and the heating water storage part 70c which accommodates heating water are formed. The rubber plate 70a is adapted to absorb the pressure change of the heating water by being deformed according to the acting pressure.
상기와 같은 대기차단형 가스보일러는, 대기개방형 가스보일러와 달리 보일러의 설치위치에 제약을 받지 않고, 난방수 순환계가 대기와 차단되어 있어 난방수로 산소가 유입되는 것을 방지할 수 있는 장점이 있는 반면, 기체저장부(70b) 내부에 충진된 기체의 가스압에 의하여 난방수의 압력변화를 흡수하기 때문에 장기간 사용시 그 기능이 떨어지게 되고, 내부에 가스를 충진하는 구조로 이루어져 있어 그 구조가 복잡하므로 제작이 용이하지 않고 제조 비용이 고가일 뿐만 아니라 스틸 재질로 이루어져 있어 부식의 우려가 있는 단점이 있다.Unlike the atmospheric open gas boiler, the above-described atmospheric cut-off gas boiler is not limited to the installation position of the boiler, and the heating water circulation system is blocked from the atmosphere, which has the advantage of preventing oxygen from flowing into the heating water. On the other hand, due to the gas pressure of the gas filled in the gas storage unit (70b) absorbs the pressure change of the heating water, its function is reduced when used for a long time, and the structure is made of a structure that is filled with the gas inside the structure is complicated This is not easy and the manufacturing cost is not only expensive, but also made of a steel material has the disadvantage that there is a risk of corrosion.
상기와 같이 종래의 개방형 팽창탱크(50)는 설치위치의 제약과 난방배관의 부식이 유발되는 단점이 있고, 종래의 밀폐형 팽창탱크(70)는 구조가 복잡하여 제작이 용이하지 않고 제조 비용이 고가인 단점이 있으므로, 이러한 종래 팽창탱크들의 단점을 보완할 수 있는 구조로 이루어진 팽창탱크의 개발이 요구된다.As described above, the conventional open type expansion tank 50 has the disadvantage of causing limitations in the installation position and corrosion of the heating pipe, and the conventional closed type expansion tank 70 is not easy to manufacture due to the complicated structure and high manufacturing cost. Since there is a disadvantage, it is required to develop an expansion tank made of a structure that can compensate for the disadvantages of these conventional expansion tanks.
