본 고안은 심지식 석유보일러의 과열방지장치에 관한 것으로, 보일러의 연소상태가 필요이상으로 과열하게 되면 이를 감지하여 연료공급을 자동차단시켜 보일러의 과열을 방지케한 것이다.The present invention relates to an overheat prevention device of a petroleum oil boiler, and when the combustion state of the boiler is overheated more than necessary, it detects this and cuts off the fuel supply to prevent the boiler from overheating.

종래에도 써머스타트의 온도감지작동에 의해 보일러의 과열을 방지토록한 것이 있었다. 즉, 도면 제1도에서 예시하고 있는 바와같이 써머스타트(4)에 연결시킨 전자석(17)(17')에 의해 두개의 승강 개폐봉(10)(10')을 승강시키므로서 개폐봉(10)(10')의 하단이 급유공(12)(12')을 개폐시키도록 구성한 것이었다.Conventionally, there was a thing which prevented overheating of a boiler by the temperature sensing operation of a thermostart. That is, as illustrated in FIG. 1, the elevating opening and closing rods 10 and 10 ′ are lifted and lifted by the electromagnets 17 and 17 ′ connected to the thermal start 4. 10 'was configured to open and close the oil supply holes 12 and 12'.

그러나 이는 전원 차단시 두개의 승강개폐봉(10)(10')이 스프링(11)(11')의 강한 압력으로 하강되어 급유공(12)(12')을 막아주도록 구성된 것이어서 이를 다시 상승시키려면 전원을 공급하여 두개의 전자석(17)(17')에 자력을 발생시켜야만 되는 것이었다. 따라서 전력소모가 많았음은 물론 두개의 급유공(12)(12')을 개폐시킬 때 그 개폐상태가 불안정하게 될 우려가 많고 사용부품수가 많고 구조가 복잡하여서 고장발생률이 높고 제작비용이 증가되는 문제가 있는 것이다.However, when the power is cut off, the two lifting opening and closing rods 10 and 10 'are configured to lower the strong pressure of the springs 11 and 11' to block the oil supply holes 12 and 12 'and thus raise them again. In order to supply power, two electromagnets 17 and 17 'had to be magnetically generated. Therefore, the power consumption is high, and when opening and closing the two lubrication holes 12, 12 ', there is a high possibility that the opening and closing state is unstable, the number of parts used and the structure is complicated, the failure rate is high and the production cost is increased. There is a problem.

본 고안은 상기와 같은 기존의 과열방지장치가 지니고있는 문제점을 해결하여 전자석을 사용치않고 써머스타트의 작동축으로 개폐봉을 연동 하강시켜 심지통으로의 급유를 차단케하여 과열을 방지하고 재점화시에는 수동복귀 손잡이의 당김작동으로 개폐봉을 상승시켜 재급유케하여 전력소모를 대폭줄이고 개폐봉의 개폐상태를 정확히 하도록 하는데 그 목적이 있는 것이다.The present invention solves the problems of the conventional overheat prevention device as described above, by interlocking the opening and closing rod to the working shaft of the thermal start without using an electromagnet to block the oil supply to the core wick to prevent overheating and re-ignition The purpose of this is to raise and close the opening and closing rod by pulling operation of the manual return handle to drastically reduce power consumption and to accurately open and close the opening and closing rod.

본 고안의 내용을 첨부도면에 의거 상세히 설명하면 다음과 같다. 스프링(11)에 의해 탄발지지된 승강개폐봉(10)이 급유공(12)을 개폐하도록 구성한 유량조절기(13)를 설치하여 되는 심지식 석유보일러의 과열방지장치에 있어서, 가압봉(2)이 하향돌설된 작동레버(1)의 일단을 유량조절기(13)의 뚜껑상부에 고정시킨 축수편(3)에 굴대설치하고, 수조(14)의 하단에 설치한 써머스타트(4)의 승강작동축(5) 하단은 작동레버(1)의 상면에 접촉된 상태를 유지토록 하며, 작동레버(1)의 선단이 끼워지는 삽입홈(6a)과 스토파(7)의 선단이 끼워지는 삽입홈(6b)이 형성된 캠(6)을 지지대(8)에 굴대 설치하여 수동복귀손잡이(7a)를 가진 스토파(7)의 선단이 캠(6)의 외주면에 접촉된 상태로 스프링(9)에 의해 탄발지지되게 구성하여 됨을 특징으로한 심지식 석유보일러의 과열방지장치인 것이다.Referring to the contents of the present invention in detail based on the accompanying drawings as follows. In the overheat preventing device of the wick oil boiler, which is provided with a flow regulator 13 configured to open and close the oil supply hole 12 by the lift opening / closing rod 10 supported by the spring 11, the pressure rod 2 One end of the downwardly actuated operating lever 1 is mounted on the shaft bearing piece 3 fixed to the upper part of the lid of the flow regulator 13, and the raising and lowering operation of the summer start 4 installed at the lower end of the water tank 14 is carried out. The lower end of the shaft 5 is in contact with the upper surface of the operating lever 1, and the insertion groove 6a into which the tip of the operating lever 1 is fitted and the insertion groove into which the tip of the stopper 7 are fitted. A cam 6 having a 6b formed therein is a mandrel mounted to the support 8 so that the tip of the stopper 7 having the manual return handle 7a contacts the outer circumferential surface of the cam 6 to the spring 9. It is to prevent overheating of the wicking oil boiler, characterized in that it is configured to be supported by the bullet.

첨부도면중 미셜명부호 15는 개폐봉작동판, 16은 후로트밸브를 나타내는 것이다.In the accompanying drawings, the reference numeral 15 denotes an open / close rod operating plate, and 16 denotes a float valve.

본 고안의 작동상태를 도면 제4도에 의거 설명하면, 수조(14)내의 수온이 과열되면 이를 감지한 써머스타트(4)가 감온작동하여 승강작동축(5)을 하강시키게된다.Referring to the operating state of the present invention based on Figure 4, when the water temperature in the water tank 14 is overheated, the thermal start (4) that senses this to lower the operating shaft (5).

이렇게 하강된 작동축(5)은 그 하단에 접촉상태로 설치된 작동레버(1)를 가압하게 되고 이 작동레버(1)에 하향 돌설시킨 가압봉(2)을 하강시키게되는데 상기 가압봉(2)은 유량조절기(13)의 내부에 설치된 개폐봉작동편(15)을 눌러 스프링(11)을 압축시키면서 개폐봉(10)을 하강시켜서 급유공(12)을 막아주므로서 심지통쪽으로의 연료공급이 차단되어 가열온도를 약화시켜줌에 따라 보일러의 과열을 방지하여 주게 된다. 이때 작동레버(1)의 선단은 캠(6)의 삽입홈(6a)에 끼워진 상태이므로 캠(6)을 회전작동시키게 되는데 작동레버(1)의 가압시 캠(6)은 반시계방향으로 회전되면서 스토파 삽입홈(6b)이 스토파(7)의 선단위치에 이르렀을때 캠(6)의 외주면에 접촉상태로 있는 스토파(7)의 선단이 스프링(9)의 탄발압력으로 삽입홈(6b)에 끼워지게되어 캠(6)의 회전을 정지시켜주므로서 작동레버(1)를 비롯한 연동부품들이 필요이상의 하강은 물론 임의 상승작동을 방지하여 스톱상태를 유지하게 주게된다.The lowered working shaft 5 presses the operating lever 1 installed in contact with the lower end thereof and lowers the pressure bar 2 protruding downward from the operating lever 1. Presses the opening / closing rod operating piece 15 installed inside the flow regulator 13 to compress the spring 11 while lowering the opening / closing rod 10 to block the oil supply hole 12 so that fuel supply to the wick is blocked. As it weakens the heating temperature, it prevents overheating of the boiler. At this time, the tip of the actuating lever 1 is inserted into the insertion groove 6a of the cam 6 so that the cam 6 is rotated. When the actuating lever 1 is pressurized, the cam 6 rotates counterclockwise. When the stopper insertion groove 6b reaches the tip position of the stopper 7, the tip of the stopper 7 which is in contact with the outer circumferential surface of the cam 6 is inserted by the spring pressure of the spring 9. It is fitted to the (6b) to stop the rotation of the cam 6, the interlocking parts, including the operating lever (1) is to maintain the stop state by preventing the ascending and falling as well as any upward movement than necessary.

이후, 연료를 재공급하여 보일러를 다시 가열시키고자 할때에는 도면 제5도에서 보는 바와같이 수동복귀손잡이(7a)를 당겨 스프링(9)을 압축시키면서 스토파(7)의 선단이 삽입홈(6b)에서 빠져나오게하여 스톱상태를 해제시키면 승강개폐봉(10)에 권설된 스프링(11)이 탄발복귀되면서 급유구(12)를 막고있던 승강개폐봉(10)을 상승시키게 됨에 따라 개폐봉작동편(15)과 가압봉(2), 작동레버(1), 작동축(5)이 차례로 연동하여 상승하게되고 막혀있던 급유구(12)는 개방상태가 되어 이를통해 연료가 재공급되므로서 보일러의 정상적인 착화연소 작동을 개시하게 되는 것이다.Subsequently, when the fuel is to be resupplied to heat the boiler again, as shown in FIG. 5, the end of the stopper 7 is inserted into the insertion groove 6b while pulling the manual return handle 7a to compress the spring 9. By releasing the stop state by escaping from the spring), the spring 11 recommended on the elevating opening and closing rod 10 is raised and lifted up and down as the lifting opening and closing rod 10 blocking the oil inlet 12 is opened and closed. 15) and the pressure rod (2), the operating lever (1), the operating shaft (5) is raised in order to interlock, and the oil supply hole (12) that is blocked is opened and the fuel is supplied again through this to normal operation of the boiler It will start the ignition combustion operation.

본 고안은 이상 설명한 바와같이 전자석을 사용하지 않고 써머스타트의 작동만으로 정확한 급유차단 작동을 하여 과열을 방지할 수 있도록 구성된 것으로, 전력소모를 극소화 시켜주게되며, 그 구성도 하나의 승강개폐봉으로 간단하게 이루어진 것이어서 고장이나 오동작의 염려가 없음은 물론 생산성이 높아 보다 염가로 제작 설치할 수 있게되는 원가절감 효과도 제공하는 것이다.The present invention is configured to prevent overheating by performing accurate oil shut-off operation only by operating the thermal start without using an electromagnet as described above, and it minimizes power consumption, and its configuration is also simple with one lifting and closing rod. Since it is made so that there is no fear of malfunction or malfunction, it also provides a cost saving effect that enables higher-cost manufacturing and installation.
