본 고안은 가스보일러의 난방회로 영역에서 난방수 순환의 이상상태(비정상) 발생시 전기적인 제어와 기구적인 순환경로의 가변 대응하는 연계동작으로 순환펌프보호와 연소기로부터 열교환기 보호 및 연료소모를 방지할 수 있도록한 단순구조로된 가스보일러의 이상상태 제어장치를 제공하는데 그 목적이 있다.The present invention prevents the circulation pump and protects the heat exchanger from the combustor and prevents fuel consumption by the interlocking operation corresponding to the electric control and the variable circulation path in the event of an abnormal state (abnormal) of the heating water circulation in the heating circuit area of the gas boiler. It is an object of the present invention to provide an apparatus for controlling an abnormal state of a gas boiler having a simple structure.

종래의 가스보일러는 난방수 순환회로 중에서 여러형태의 이상상태(막힘상태, 물이없거나, 부족한 상태 등)에 대응하여 난방수에 대한 열교환 및 순환계통을 가져오게하는 순환펌프 및 연소기 등에 대한 보호를 위한 제어장치가 절대적으로 요구되고 있다.Conventional gas boilers provide protection against circulating pumps and combustors that bring about heat exchange and circulation systems for heating water in response to various types of abnormalities (blockage, no water, insufficient water, etc.) in the heating water circulation circuit. There is absolutely a need for a control device.

이와같이 가스보일러의 난방수 순환계통에 동원되는 기계적인 장치 보호를 위한 장치로서는 최근에 “일본국 공개실용신안공보 소 56-128421호)에서 소개되고 있다.As such, a device for protecting a mechanical device mobilized in the heating water circulation system of a gas boiler has recently been introduced in Japanese Unexamined Utility Model Publication No. 56-128421.

그 내용에 의하면, 난방수 순환회로 중에서 난방회로 영역내에서 막힘현상 발생시 다이아프램식 밸브에 의한 압력차에 의해 밸브가 개방되어 난방수를 바이패스토록하여 순환펌프의 공회전에 의한 고장발생을 방지하게 되었다는 내용이나 이 경우 단순히 난방회로 영역에서 순환의 부하가 발생했을 때 바이패스 시키는 것으로서 기타상황에 대웅기능을 수행하지 못하는 결점이 있었다.According to the contents, in the heating water circulation circuit, when a blockage occurs in the heating circuit area, the valve is opened due to the pressure difference by the diaphragm valve to bypass the heating water so as to prevent the occurrence of a failure due to idling of the circulation pump. In this case, it was simply to bypass when a load of circulation occurred in the heating circuit area, and there was a drawback that it could not perform the Daewoong function in other situations.

따라서, 본 고안은 단순구조로된 하나의 수압감지제어기를 개발 채용하여 난방수 순환회로중 난방회로 영역에서 물이없거나, 부족하여 순환펌프의 정상적인 작동이 아닌 공회전상황 발생시에는 연료가스밸브와 순환펌프에 대한 전원을 차단시켜 중지토록 스윗칭 작용을 하고, 난방회로 영역에서 순환경로가 막히는 상황이 발생되었을 때는 바이패스 밸브가 개방되면서 순환펌프에 정상적으로 물이 순환토록하는 일련의 기능수행을 단순구조의 수압감지 제어기에 작용되는 압력가변에 의한 기구적인 작용과 압력스위치의 연동으로 가능케 한 것이다.Therefore, the present invention develops and adopts a single pressure sensing controller with a simple structure, so that when there is no water in the heating circuit area or lack of water in the heating water circulation circuit, the fuel gas valve and the circulation pump are generated when the idling situation is not normal operation of the circulation pump. Switching to stop the power supply to the power supply, and when the circulation path is blocked in the heating circuit area, the bypass valve is opened to perform a series of functions that normally circulate the water in the circulation pump. It is made possible by the interlocking of the pressure switch and the mechanical action by the pressure change acting on the pressure sensing controller.

이하, 본 고안에 대한 설명을 첨부된 도면에 의거 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

난방수가 순환하는 난방회로중에 순환펌프(1)의 구동으로 열교환기(2)를 통과하면서 열교환되어 난방수공급관(3)과 난방회로 영역(4)을 거쳐 난방수 흡입관(5)을 통해 다시 순환펌프(1)에 의해 펌핑되는 일반적인 난방수회로 중에서 상기 난방수 공급관(3)과 난방수 흡입관(5) 사이에 소정의 바이패스 밸브를 장착하여서된 통상의 가스보일러의 난방수 순환회로를 갖춘것에 있어서, 도면 제1도에 도시된 바와같이 순환펌프(1)와 가스밸브(6)의 스윗칭 기능을 하는 압력스위치(12)의 작동을 제어하기위한 스핀들(7a)이 일측면에 구비된 다이아프램(7)에 의해 제1실(A)과 제2실(B)로 구획되고, 제3실(B)과 제3실(C)로 구획되어진 수압감지제어기(100)를 배치한 것으로서, 난방수 공급관(3)과 연결하고, 상기 제2실(B)에는 난방수 흡입관(5)과 연결되는 한편, 제3실(C)은 난방수 공급관(3)과 연통되게 연결하면서, 상기 제2,3실(B)(C) 사이에는 압력조절나사(8)와 다이아프램(7) 사이에 바이패스밸브(9)를 사이에 두고 제1,2스프링(10a)(10b)을 개재시켜 구비하며, 상기 압력 조절나사(8)는 제3실(C)에 위치한 제2 스프링(10b)의 탄발력을 조정토록 된것이고, 바이패스밸브(9)는 그 가변에 의해 제2실(B)과 제3실(C)의 연통관계를 제어토록된 수압감지제어기(100)의 구성을 갖는다.During the heating circuit in which the heating water circulates, the heat is passed through the heat exchanger (2) by the operation of the circulation pump (1) and circulated again through the heating water suction pipe (5) through the heating water supply pipe (3) and the heating circuit region (4). In the general heating water circuit pumped by the pump (1) having a heating water circulation circuit of a conventional gas boiler by installing a predetermined bypass valve between the heating water supply pipe (3) and the heating water suction pipe (5). As shown in FIG. 1, a diaphragm having a spindle 7a on one side for controlling the operation of the pressure switch 12 serving as the switching function of the circulation pump 1 and the gas valve 6 is shown in FIG. The hydraulic pressure sensing controller 100 partitioned into the 1st chamber (A) and the 2nd chamber (B) by the pram (7), and divided into the 3rd chamber (B) and the 3rd chamber (C), It is connected to the heating water supply pipe (3), the second room (B) is connected to the heating water suction pipe (5), while the third room (C) is heating In connection with the supply pipe (3), the first and second valves (B) (C) between the pressure adjusting screw (8) and the diaphragm (7) between the bypass valve (9) between the first And two springs (10a) and (10b) interposed therebetween, and the pressure adjusting screw (8) is to adjust the elasticity of the second spring (10b) located in the third chamber (C), and bypass valve ( 9) has the structure of the pressure-sensitive-sensing controller 100 which controls the communication relationship between the 2nd chamber B and the 3rd chamber C by the variable.

미 설명부호 10은 전원스위치, 11은 점화스위치, 13은 버너, 14는 연소실인 것이다.Reference numeral 10 denotes a power switch, 11 an ignition switch, 13 a burner, and 14 a combustion chamber.

제2도는 본 고안에 따른 가스보일러의 전기회로도로서 교류전원(ACV)이 전원스위치(10) 및 점화스위치(11) 또는 압력스위치(12)를 통해 가습밸브(6) 및 순환펌프(1)를 구동시킬 수 있도록 연결 구성된 것으로, 상기 점화스위치(11)는 자동복귀 a접점스위치이며, 상기 압력스위치(12)는 제1도의 수압감지제어기(100)내의 다이아프램(7)의 일측에 구성된 스핀들(7a)의 위치가변에 따라 작동될 수 있도록 된 스위치인 것이다.2 is an electric circuit diagram of a gas boiler according to the present invention, the AC power supply (ACV) through the power switch 10 and the ignition switch 11 or the pressure switch 12 to the humidification valve 6 and the circulation pump (1) The ignition switch 11 is an automatic return a contact switch, and the pressure switch 12 is a spindle configured at one side of the diaphragm 7 in the pressure sensing controller 100 of FIG. It is a switch that can be operated according to the change of position of 7a).

제2도에서 전원스위치(10)가 오프된 상태에서는 순환펌프(1)와 가스밸브(6)의 전원이 차단된 상태이고, 본 고안에 의한 수압감지제어기(100)의 작동상태는 도면 제1a도에서와 같이 압력스위치(12)가 오프상태로 유지된다.In FIG. 2, when the power switch 10 is turned off, the power of the circulation pump 1 and the gas valve 6 is cut off, and the operating state of the hydraulic pressure sensing controller 100 according to the present invention is shown in FIG. As shown in the figure, the pressure switch 12 is kept off.

이후, 가스보일러를 가동시키기 위해 전원스위치(10)를 온 사킨후 점화스위치(11)를 온 시키게되면, 가스밸브(6)가 열리면서 제1b도에서와 같이 버너(13)로 연료가스가 공급되어 연소실(14)내에서 점화가 이루어짐과 동시에 순환펌프(1)가 구동되면서 열교환기(2)에 열교환된 난방수는 난방수공급관(3)과, 난방회로영역(4) 및 난방수 흡입관(5)으로 순환경로를 갖게되면서 난방기능을 수행한다.Subsequently, when the power switch 10 is turned on to operate the gas boiler and the ignition switch 11 is turned on, the fuel valve is supplied to the burner 13 as shown in FIG. 1B while the gas valve 6 is opened. The heating water heat-exchanged to the heat exchanger 2 while the ignition is performed in the combustion chamber 14 and the circulating pump 1 is driven is connected to the heating water supply pipe 3, the heating circuit region 4, and the heating water suction pipe 5. It has a circulation path and performs heating function.

이와같이 정상적인 난방수 순환이 계속될때의 수압감지제어기(100)내의 제1,2,3,실(A)(B)(C)의 상황은 가스보일러의 가동전의 상태인 제1a도의 상태에서 제1b도의 상태로 변화된다.Thus, the situation of the 1st, 2nd, 3rd chamber A (B) (C) in the hydraulic pressure control controller 100 when normal heating water circulation continues is 1b in the state of FIG. 1a which is a state before the operation of a gas boiler. It changes to the state of FIG.

즉, 제1실(A)은 순환펌프(1)의 펌핑에 의한 토출측에 위치한것으로서 고압상태가 되는 한편, 제2실(B)은 순환펌프(1)의 흡입측에 위치하여 저압의 상태가 유지되므로서 다이아프램(7)은 제1실(A)과 제2실(B)의 압력차에 의해 제1 스프링(10a)을 압축하면서 도면상 우측으로 밀리게되어 스핀들(7a)의 가변위치에 따라 스윗칭 기능을 수행하는 압력스위치(12)는 온 상태가 유지되어 가스밸브(6)와 순환펌프(1)가 정상적인 가동상태가 유지된다.That is, the first chamber (A) is located on the discharge side by the pumping of the circulation pump (1) and becomes a high pressure state, while the second chamber (B) is located on the suction side of the circulation pump (1) to maintain the low pressure state. While being retained, the diaphragm 7 is pushed to the right in the drawing while compressing the first spring 10a due to the pressure difference between the first chamber A and the second chamber B, and thus the variable position of the spindle 7a. As a result, the pressure switch 12 performing the switching function is maintained in an on state so that the gas valve 6 and the circulation pump 1 are normally operated.

또한, 바이패스밸브(9)의 가변을 좌우하는 제3실(C)도 순환펌프(1)의 고압측에 위치하므로 제2 실(B)과 폐쇄상태가 유지된다.In addition, since the third chamber C, which determines the variability of the bypass valve 9, is also located on the high pressure side of the circulation pump 1, the closed state of the second chamber B is maintained.

만약, 가동중에 난방회로영역(4) 내지는 난방수 공급관(3)과, 난방수 흡입관(5) 사이에 물이 없거나 부족한 상황이 발생되었을 경우에는 순환하는 물의 량이 부족하기 때문에 수입감지제어기(100)의 제1실(A)에는 압력이 걸리지 않거나 미소한 압력이 걸리게 되어 제1 스프링(10a)을 압축할 수 없는 상황이 되어 제1 스프링(10a)의 복원력에 의해 다이아프램(7)의 스핀들(7a)은 도면상 좌측으로 위치 가변되면서 압력스위치(12)는 오프상태가 된다.If there is no water or a lack of water between the heating circuit area 4 or the heating water supply pipe 3 and the heating water suction pipe 5 during operation, the amount of water circulated is insufficient. The first chamber A is not pressurized or applied with a slight pressure, so that the first spring 10a cannot be compressed, and the spindle of the diaphragm 7 is driven by the restoring force of the first spring 10a. 7a) is shifted to the left in the drawing while the pressure switch 12 is turned off.

한편, 제2실(B)과 제3실(C) 사이에는 순환펌프(1)의 토출측 및 흡입측의 위치관계에 의한 압력차에 의해 부동의 상태로 바이패스 밸브(9)는 폐쇄상태를 유지하므로서 제1c도에서와 같은 상황을 유지한다.On the other hand, between the second chamber B and the third chamber C, the bypass valve 9 is closed in a floating state due to the pressure difference due to the positional relationship between the discharge side and the suction side of the circulation pump 1. The same situation as in FIG. 1C is maintained.

한편, 상기와 같이 압력스위치(12)가 오프상태가 되므로서 제2도의 전기회로 관계에 의해 가스밸브(6)와 순환펌프(1)가 동시에 전원 차단되는 것이다.On the other hand, since the pressure switch 12 is turned off as described above, the gas valve 6 and the circulation pump 1 are simultaneously turned off by the electrical circuit relationship of FIG.

또한, 가스보일러가 정상적인 가동상황에서 난방회로영역(4)에서의 막히는 상황이 발생되었을 경우에는 상기 정상적인 순환상황(제1b도)보다 수압감지제어기(100)의 제1실(A)의 압력이 훨씬높게 작용하므로서 다이아프램(7)의 도면상 우측으로 변위정도가 훨씬 크게되면서 제1,2 스프링(10a)(10b)을 단차적으로 동시 압축하므로서 바이패스밸브(9)도 가변되어 제2,3실(B)(C)간의 통로가 개방되는 제1d도의 상황이 됨에 따라 순환펌프(1)의 토출측에 해당하는 난방수공급관(3)의 물이 수압감지제어기(100)에 구성된 바이패스밸브(9)의 개방에 의해 제3실(C)과 제2실(B)을 통과하여 순환펌프(1)의 흡입측으로 유도되어 순환펌프(1)의 공회전 상황을 방지한다.In addition, when the gas boiler is clogged in the heating circuit region 4 under normal operating conditions, the pressure in the first chamber A of the hydraulic pressure sensing controller 100 is lower than the normal circulation condition (FIG. 1B). The bypass valve 9 is also variable by simultaneously compressing the first and second springs 10a and 10b stepwise while the displacement degree is much greater to the right side of the diagram of the diaphragm 7 while acting much higher. As the condition of FIG. 1d where the passage between the three chambers (B) and (C) is opened, the water of the heating water supply pipe 3 corresponding to the discharge side of the circulation pump 1 is configured in the water pressure sensor controller 100. By opening (9), it passes through the third chamber (C) and the second chamber (B) and is led to the suction side of the circulation pump (1) to prevent the idling situation of the circulation pump (1).

여기서, 상기와 같이 가스보일러의 가동전상태(제1a도상태), 정상적인 가동상태(제1b도상태), 난방회로 영역에 물이 없거나 부족한 상태(제1c도상태), 그리고 난방회로 영역에서 막혔을때의 상태(제1c도상태)로 작동되는 제1,2스프링(10a)(10b)의 복원력의 세기관계 및 제1,2,3,실(A)(B)(C)의 압력관계에 의한 다이아프램(7)과 바이패스밸브(9)의 관계를 설명하기로 한다.Here, as described above, the gas boiler may be blocked in the pre-operation state (FIG. 1a state), the normal operation state (FIG. 1b state), the absence or lack of water in the heating circuit region (FIG. 1c state), and the heating circuit region. In relation to the strength relationship of the restoring force of the first and second springs 10a and 10b operated in the state of FIG. The relationship between the diaphragm 7 and the bypass valve 9 will be described.

보일러에 대한 가동전의 상태인 제1a도의 상태는 제1,2,3실(A)(B)(C)에 작용되는 압력은 동일한 평형상태이고, 제1 스프링(10a)은 제2 스프링(10b)보다 복원력의 세기가 작은것을 채택한 것이므로 제1 스프링(10a)는 복원력이 작용되지 않는 해제상태로 다이아프램(7)에 대해 지지하고, 제2 스프링(10b)은 바이패스밸브(9)로 하여금 통로를 차단상태가 유지된다.The state of FIG. 1a which is the state before operation | movement with respect to a boiler is the pressure applied to the 1st, 2nd, 3rd room (A) (B) (C) is the same equilibrium state, and the 1st spring 10a is the 2nd spring 10b. Since the strength of the restoring force is smaller than), the first spring 10a supports the diaphragm 7 in a released state in which the restoring force is not applied, and the second spring 10b causes the bypass valve 9 to The passage is kept blocked.

즉, 힘의세기(복원력의 세기)에서 제1 스프링(10a) 〈 제2 스프링(10b)의 등식이 성립되어 도면 제1a도 상태가 유지된다.That is, the equation of the first spring 10a < the second spring 10b is established at the strength of the force (the strength of the restoring force), so that the state of FIG. 1a is maintained.

보이러가 정상적인 가동을 했을 때, 제1b도의 상태를 유지하기 까지는 순환펌프(1)의 가동으로 수압이 상기 가동전의 상태에서 제1실(A)과 제3실(C)에만 작용되므로 제3실(C)에 영향을 받는 바이패스밸브(9)에는 수압이 가중되어 밀폐력으로 작용되는 한편, 제1실(A)에도 수압이 작용되어 다이아프램(7)의 스핀들(7a)이 압력스위치(12)가 “온”상태가 될정도까지 도면 제1b도와 같은 상태로 가변된다.When the boiler is normally operated, the hydraulic pressure is applied only to the first chamber A and the third chamber C in the state before the operation until the circulation pump 1 is maintained until the state of FIG. 1b is maintained. Water pressure is applied to the bypass valve 9 affected by the seal C to act as a sealing force, while water pressure is also applied to the first chamber A so that the spindle 7a of the diaphragm 7 is a pressure switch ( The state is changed to the state shown in FIG. 1B until the state 12) becomes "ON".

이때, 제1 스프링(10a)은 압축하게되나 제2 스프링(10b)의 복원력이 세기때문에 바이패스밸브(9)는 움직이지 않고 통로를 밀폐상태가 유지된다.At this time, the first spring 10a is compressed but the bypass valve 9 does not move because the restoring force of the second spring 10b is strong, and the passage is kept closed.

한편, 순환펌프(1)에 의해 펌핑되는 난방수가 부족하거나 없을 때는 보일러를 가동시켜도 제1실(A)에 수압이 적거나 작용되지 않기때문에 제1 스프링(10a)의 복원력에 의해 다이아프램(7)의 스핀들(7a)은 도면 제1c도에서와 같이 이동되어 압력스위치(12)에 대해 “오프”동작을 가져오게 된다.On the other hand, when the heating water pumped by the circulation pump 1 is insufficient or absent even if the boiler is operated, the water pressure is not applied or acted on the first chamber (A). Spindle 7a is moved as shown in FIG. 1C, resulting in an " off "

또한, 난방회로 영역에서 막혔을때는 높은 수압이 제1,3실(A)(C)에 작용된다. 이때 제1실(A)의 다이아프램(7)에 작용되는 압력과 제3(C)에 작용되는 압력은 동일하나 바이패스밸브(9)에 압력 작용면적보다 제1실(A)에 위치한 다이아프램(7)의 압력작용 면적이 훨씬 크기때문제 제1 스프링(10a)을 가압하게되고, 가압되는 변위가 크기때문에 비례적으로 제1 스프링(10a)에 작용되는 복원력의 세기는 제2 스프링(10b)의 세기보다 크게 변화되어 (제1 스프링(10a) 〉제2 스프링(10b)) 제2 스프링(10b)을 가압하면서 도면 제1d도에 도시된 바와같이 바이패스밸브(9)는 개방상태가 된다. 한편 바이패스밸브(9)가 개방되어진 상태에서 제2실(B)의 상태가 순환펌프(1)의 흡입측에 연결되어 있기 때문에 순환펌프(1)의 출력측과 연결되어진 제1실(A)의 압력보다 낮은 상태로 제2실(B)의 상태가 유지되면서 난방수의 바이패스가 계속진행된다. 이와같이 바이패스 작동이 장시간 경과되는 과정에서 제1실(A)과 제2실(B)이 동일한 압력의 평형이 일시적인 현상으로 발생되면, 짧은시간동안 바이패스 동작이 멈추었다(바이패스밸브(9) 폐쇄) 다시 바이패스밸브(9)가 개방되어지는 작동관계를 지니는 것이다.In addition, when blocked in the heating circuit area, high water pressure is applied to the first and third rooms (A) and (C). At this time, the pressure acting on the diaphragm 7 of the first chamber A and the pressure acting on the third C are the same, but the diaphragm located in the first chamber A is larger than the pressure operating area of the bypass valve 9. Problem when the pressure action area of the pram 7 is much larger The first spring 10a is pressed, and because of the large displacement, the strength of the restoring force acting on the first spring 10a is proportionally increased by the second spring. Bypassing the strength of 10b) (first spring 10a > second spring 10b) while pressing the second spring 10b, the bypass valve 9 is opened as shown in FIG. 1d. Becomes Meanwhile, since the state of the second chamber B is connected to the suction side of the circulation pump 1 while the bypass valve 9 is open, the first chamber A is connected to the output side of the circulation pump 1. Bypassing the heating water continues while the state of the second chamber B is maintained at a lower pressure than. In this way, if the first chamber A and the second chamber B have a temporary balance of the same pressure during a long time, the bypass operation was stopped for a short time (bypass valve 9). Closed) The bypass valve 9 has an operating relationship in which it is opened again.

이상에서와 같이 가스보일러의 난방수 순환회로상에 이상상태에 의해 변화되는 압력의 변화를 이용하여 순환펌프(1)에 대한 공회전 및 과부하로 인한 고장발생을 방지하게 된것이다.As described above, the occurrence of failure due to idling and overload of the circulation pump 1 is prevented by using a change in pressure that is changed by an abnormal state on the heating water circulation circuit of the gas boiler.

즉, 본 고안의 특징적인 기술내용은 바이패스밸브(9)를 수납하고 있는 단순구조의 수압감지제어기(100)를 개발하여 난방수 순환을 좌우하는 순환펌프(1) 보호목적을 달성함과 아울러, 그에 동원되는 수압감지제어기(100)의 구조단순화를 꾀하게 된것이다.That is, the characteristic technical features of the present invention is to develop a pressure sensing controller 100 having a simple structure accommodating the bypass valve 9 to achieve the protection purpose of the circulation pump 1 that influences the circulation of the heating water. , It is intended to simplify the structure of the hydraulic pressure sensing controller 100 mobilized thereon.
