Description
본 발명은 초소형 밀폐형 온수보일러의 자동 수압제어방법 및 그 장치에 관한 것이다.The present invention relates to an automatic hydraulic pressure control method for an ultra-small sealed hot water boiler and an apparatus thereof.
일반적으로 온수보일러의 환수관측에 팽창탱크를 대기에 개방된 상태로 연결하여, 온수의 수압변동에 따라 팽창탱크의 수위변동으로 수압을 제어하게 되어 있다.In general, the expansion tank is connected to the return pipe side of the hot water boiler in an open state to control the water pressure by the water level change of the expansion tank according to the water pressure change of the hot water.
그러나 전체 방열관의 온수량이 불과 2ℓ정도이고 보일러의 용량은 약 300㏄정도에 불과한 초소형 온수 보일러는 실내에서 침대별로 사용하기 때문에 한 장소에 고정 설치하는 것이 아니고 침대 곁에나 임의 위치에 놓고 사용하는 만큼 온수 보일러마다 팽창탱크를 대기에 노출되게 설치하는 것은 매우 번거롭고 불편한 문제점이 있다.However, the ultra-small hot water boiler, which has only 2 liters of hot water in the entire heat pipe and the boiler's capacity is about 300㏄, is used for each bed indoors, so it is not fixed to one place. As long as the hot water boiler to install the expansion tank exposed to the atmosphere has a very troublesome and inconvenient problem.
따라서 보일러와 방열관을 포함하는 전체 온수 순환계의 공간에 물을 채워 밀폐하여 사용하는 바, 온수 순환계의 전체 온수량에 비하여 보일러의 온수량은 작고 가열온도 역시 60℃ 정도이기 때문에 유체의 과팽창으로 인한 보일러나 방열관이 터지는 일은 없는데, 합성수지제인 방열관이 겹쳐진 상태에서 펴지거나 늘어나거나 기타 어떠한 원인으로 온수 순환계의 용적이 확장되면 밀폐공간내의 온수량에 대하여 여분의 공간이 생긴다.Therefore, the water is sealed and used in the space of the whole hot water circulation system including the boiler and the heat dissipation pipe. Compared to the total hot water volume of the hot water circulation system, the hot water amount of the boiler is small and the heating temperature is about 60 ° C. The boiler or heat dissipation tube is not blown out. If the heat dissipation tube made of synthetic resin is unfolded or expanded, or if the volume of the hot water circulation system is expanded due to any other reason, extra space is created for the amount of hot water in the enclosed space.
이 공간은 공기 등의 기체가 채워져서 내경이 작은 방열관으로의 온수 순환을 장해 할 뿐 아니라 펌프기구의 펌프실에 온수가 차여 있지 않으면 펌프동작이 공회전되어 온수의 순환작용이 제대로 이루어지지 않는 문제점이 있었다.This space not only prevents hot water circulation to heat pipes with small inner diameter due to filling of gas such as air, but also if the hot water is not filled in the pump room of the pump mechanism, the pump operation is idle and the circulation of hot water is not properly performed. there was.
이러한 펌프기구에 의한 온수의 순환작용이 저해되면 보일러 측에서는 지정된 온도 이상으로는 가열되지 않겠지만 방열관 측으로는 온수가 공급되지 못하므로 난방을 유효하게 유지하기 어려운 문제가 있다.When the circulation action of the hot water is inhibited by the pump mechanism, the boiler side may not be heated above a predetermined temperature, but since the hot water may not be supplied to the heat radiating tube side, it is difficult to maintain the heating effectively.
본 발명의 목적은 초소형 온수보일러와 방열관을 포함하는 온수 순환계를 대기와 밀폐한 상태에서 펌프기구의 흡입구측에 수압유지수단을 개재시키어 온수의 펌핑기능이 유지되는 조건으로 수압을 자동 유지하는 방법과 그 장치를 제공하려는데 있다.An object of the present invention is to automatically maintain the water pressure under the condition that the pumping function of the hot water is maintained by interposing a water pressure maintaining means on the inlet side of the pump mechanism in a state in which the hot water circulation system including the ultra-small hot water boiler and the heat dissipation tube is sealed with the air. And to provide that device.
본 발명의 또 다른 목적은 온수보일러의 온수 순환장해 요인을 해소하고 온수 순환계에서 펌프기구에 의하여 온수가 원활하게 방열관으로 순환 공급되어 유효하게 난방을 유지할 수 있게 하는데 있다.Still another object of the present invention is to solve the hot water circulation obstacles of the hot water boiler and to circulate the hot water smoothly by the pump mechanism in the hot water circulation system to the heat radiating pipe to effectively maintain the heating.
본 발명의 이러한 목적을 달성하기 위하여, 전열히터가 구비된 온수의 보일러기구와 온수를 순환시키는 펌프기구가 결합된 난방용 소형 보일러에 있어서, 펌프기구의 부압이 작용하는 흡입구와 온수의 환수구 사이에 탄성질 팽창관이 연관된 수압유지수단을 개재시키고 보일러와 방열관을 비롯한 전 순환계의 밀폐 공간 내에 정용량에서 약 5∼10%용량을 더 주입하여 수압 유지수단의 팽창관이 어느 정도 팽창된 상태로 한다.In order to achieve this object of the present invention, in a small boiler for heating combined with a boiler mechanism of hot water with a heat transfer heater and a pump mechanism for circulating hot water, between the inlet port of the negative pressure of the pump mechanism and the return port of hot water The expansion tube of the hydraulic pressure maintaining means is expanded to some extent by interposing the hydraulic pressure holding means associated with the elastic expansion pipe and injecting about 5 to 10% of the fixed capacity into the sealed space of the entire circulation system including the boiler and the heat dissipating pipe. do.
팽창관의 자체 탄성에 의한 수축되려는 가압작용으로 펌프의 흡입구측의 수압을 펌핑가능한 조건으로 유지시키는 방법에 의하여, 온수의 순환계의 내부용적이 어떤 원인으로 확장되어 여분의 공간이 생기는 경우라도 펌프기구의 펌프실에는 펌핑작용을 유지할 수 있는 수압이 유지되고 있기 때문에 온수가 방열관으로 원활하게 공급 순환되어 유효하게 난방할 수 있게 한 것이다.The pump mechanism maintains the water pressure at the inlet side of the pump in a pumpable condition due to the pressurizing action of contraction caused by the elasticity of the expansion tube. In the pump room of the water pressure to maintain the pumping action is maintained, so that hot water is smoothly supplied to the heat radiating pipe to be able to effectively heat.

도1에 표시한 바와 같이 전열히터(h)가 내장되어 온수를 소정의 온도로 가열하는 보일러기구(B)와 방열관(R)에서 환류된 온수를 보일러기구(B)로 공급하는 모터 펌프기구(P)가 결합된 초소형 보일러에 있어서, 펌프기구(P)의 가동 시에 부압(負壓)이 작용하는 흡입구(b)와 온수의 환수구(a) 사이에 통기구(av)를 가진 팽창실(C)을 형성하고 실리콘 고무와 같은 탄성질 팽창관(T)의 양단부를 상기 환수구(a)와 흡입구(b)에 연결하여 구성된 수압제어수단(ED)을 개재시키고 온수의 순환계 내에서의 예상되는 온수의 감소량을 감안(勘案)하여 처음부터 정용량보다 약 5∼10%정도의 용량을 증가시키어 벨브(v)의 주입구(s)를 통하여 주입하여 팽창관(T)이 팽창된 상태로 밀폐한다.As shown in Fig. 1, a heat-transfer heater (h) is built-in and a motor pump mechanism for supplying hot water refluxed from the radiator pipe (R) to the boiler mechanism (B) for heating hot water to a predetermined temperature. In the micro boiler combined with (P), an expansion chamber having an air vent (av) between a suction port (b) in which a negative pressure acts upon operation of the pump mechanism (P) and a return port (a) of hot water. (C) is formed and the both ends of the elastic expansion tube (T), such as silicone rubber, are connected to the return port (a) and the suction port (b) to interpose hydraulic pressure control means (ED) formed in the circulation system of hot water. In consideration of the expected decrease in the amount of hot water, the inflation tube T is expanded by injecting it through the inlet s of the valve v, increasing the capacity by about 5 to 10% from the initial capacity. Seal it.
이때의 수압은 펌프기구(P)의 펌프실(cp)의 흡입구(b)측에 가장 직접적으로 작용하기 때문에 펌프기구(P)가 가동하면 펌프로터(f)의 회전에 의하여 온수는 도관(d2)을 통하여 보일러기구(B)로 공급되고 여기에서 전열히터(h)에 의하여 소정의 온도로 가열된 다음 도관(d3)을 통하여 방열관(R)으로 공급된다. 방열관(R)에서 방열로 냉각된 온수는 도관(d1)을 통하여 환수구(a)를 거쳐 팽창관(T)을 통과하여 흡입구(b)로 유입되어 펌프기구(P)의 가동으로 온수는 계속 공급 순환된다.Since the water pressure at this time acts directly on the suction port b side of the pump chamber cp of the pump mechanism P, when the pump mechanism P is operated, the hot water is conduit d2 by the rotation of the pump rotor f. It is supplied to the boiler mechanism (B) through which it is heated to a predetermined temperature by the heat transfer heater (h) and then supplied to the heat radiation pipe (R) through the conduit (d3). The hot water cooled by the heat dissipation in the heat dissipation pipe (R) is introduced into the inlet (b) through the expansion pipe (T) through the conduit (d) through the inlet (a), and the hot water is operated by the operation of the pump mechanism (P). The supply cycle continues.
만약, 어떤 원인으로 온수의 순환계의 내부용적이 약간이라도 확장되면 그만큼의 수압변동에 대하여 수압유지수단(ED)의 팽창관(T)이 자기 탄성적 수축력에 의하여 펌프실(cp)에 대한 가압작용이 일어나 수압을 보충하여 펌프기능을 유지시킨다. 또 온수의 온도변화에 따른 용적변화에 대하여도 수압유지수단(ED)의 팽창관 (T)이 유효하게 대응하여 수압변동을 흡수 완화하게 된다. 팽창실(C)은 팽창관(T)을 보호하며 통기구(av)를 통한 내외 공기의 유통에 의하여 팽창관(T)의 용적변화에 제약을 주지 않는다.If, for some reason, the internal volume of the circulation of the hot water is slightly expanded, the expansion pipe T of the hydraulic pressure holding means ED presses against the pump chamber cp due to the self-elastic contraction force. To replenish the water pressure to maintain the pump function. In addition, the expansion pipe T of the hydraulic pressure holding means ED effectively responds to the volume change caused by the temperature change of the hot water, thereby absorbing and mitigating the hydraulic pressure fluctuation. The expansion chamber (C) protects the expansion pipe (T) and does not restrict the volume change of the expansion pipe (T) by the flow of air inside and outside through the vent (av).
온수의 용량감소의 경우 뿐 아니라 물에 용해된 공기가 분리 및 응집되어 큰 기포로 펌프실에 유입되는 경우에도 수압유지수단(ED)의 팽창관의 압축작용으로 펌프실 외부로 공기가 밀리게 됨으로 펌프기구(P)의 로터가 공회전되는 일이 없이 펌프기능이 유지된다. 펌프기능이 유지되면 온수의 순환작용이 유지되기 때문에 보일러기구에서 가열된 온수의 공급에 의하여 유효하게 난방 할 수 있는 것이다.In addition to the case of reducing the capacity of hot water, even when air dissolved in water is separated and agglomerated and flows into the pump chamber with large bubbles, the air is pushed out of the pump chamber by the compression of the expansion pipe of the hydraulic pressure holding means (ED). The pump function is maintained without idling the rotor of (P). If the pump function is maintained, the circulation of hot water is maintained, so that it can be effectively heated by the supply of hot water heated by the boiler apparatus.
또 밸브(v)의 주입구(s)를 통하여 온수 순환계 내의 공기를 배기하거나 부족한 물을 보충할 수 있다. 그러나 대부분의 경우 밀폐상태로 장기간 사용이 가능하다.In addition, through the inlet s of the valve v, the air in the hot water circulation system can be exhausted or the insufficient water can be replenished. However, in most cases, it can be used for a long time in a sealed state.
본 발명은 보일러기구와 펌프기구가 결합된 초소형 보일러에 있어서, 펌프기구의 흡입구와 환수구 사이에 탄성질 팽창관을 연결하여서 된 수압유지수단을 개재시키고 팽창관이 어느 정도 팽창상태로 물을 주입하고 밀폐하여 펌프기구의 흡입구에 항상 수압이 작용할 수 있게 하였기 때문에 어떤 원인으로 온수 순환계의 내부용적의 확장으로 이미 주입된 온수량의 부족하여 수압이 저하되는 경우, 수압유지수단의 팽창관의 수축작용으로 펌프기능을 유지할 수 있는 수압을 자동 유지하여 온수를 원활하게 공급 순환하여 유효하게 난방할 수 있는 효과가 있다.The present invention is an ultra-small boiler in which a boiler mechanism and a pump mechanism are combined, interposing a pressure expansion means formed by connecting an elastic expansion tube between a suction port and a return port of the pump mechanism, and injecting water in an expansion state in which the expansion tube is expanded to some extent. Since the water pressure is always applied to the suction port of the pump mechanism due to expansion of the internal volume of the hot water circulation system, if the water pressure decreases due to the lack of the amount of hot water already injected, the contraction action of the expansion pipe of the hydraulic pressure retention means By automatically maintaining the water pressure to maintain the pump function, there is an effect that can effectively heat the hot water supply circulation.
