The present invention is a flow path for preventing the overpressure of the portable gas range to prevent the danger by blocking the flow path in the event of an accident caused by the overpressure of the portable gas range using liquefied butane gas as fuel, and to open the flow path when reuse after blocking the flow path. A safety regulator with a shut-off and return device. More specifically, a shut-off valve, which is a shielding means for operating by an overpressure of gas at an inner end of a gas inflow path, in a structure in which a gas inflow path and a gas discharge path are formed on the same line. The cam is provided in a three-stage structure and the reset button protruded by the overpressure is provided with a cam installed inside the knob knob to operate the return lever to open the blocked flow path.
일반적으로 액화 부탄가스를 연료로 사용하는 휴대용 가스레인지는 그 구조가 간단하고 취급과 사용이 간편하여 실내뿐만 아니라 야외에서도 다양한 형태의 가열수단으로 사용되고 있으나 사용자의 부주의로 가스가 누출되어 폭발 및 화재의 원인이 되고 있어 여러 형태의 안전장치가 개발되고 있으며 상기의 안전장치는 대부분 열과 압력변화를 감지하여 가스콕크로부터 부탄가스 용기를 분리시켜 가스공급을 중단시키는 방법 또는 열과 압력변화를 제어하기 위하여 감지실린더나 센서를 활용하고 있으나 잦은 고장과 오작동으로 인한 이차적인 사고의 위험이 있어 가스레인지 자체에 장착된 가스콕크에서 가스의 누설을 감지하고 차단하는 장치가 요구되고 있는 실정이다.In general, portable gas ranges using liquefied butane gas as fuel are used for various types of heating means not only indoors but also outdoors because of their simple structure and easy handling and use. Various types of safety devices have been developed, and most of the safety devices detect heat and pressure changes to separate butane gas containers from gas cocks and stop the gas supply, or control cylinders to control heat and pressure changes. However, although sensors are used, there is a risk of secondary accidents due to frequent failures and malfunctions. Therefore, a device for detecting and blocking the leakage of gas in the gas cock installed in the gas range itself is required.
종래의 안전콕크로는 실용신안등록 제20-199484호(휴대용 가스레인지의 안전콕크)와 특허등록 제10-0883308호(개선된 유로를 갖는 휴대용 가스레인지의 안전콕크)가 제시되었다.As a conventional safety cock, Utility Model Registration No. 20-199484 (Safety Cock for Portable Gas Range) and Patent Registration No. 10-0883308 (Safety Cock for Portable Gas Range with Improved Flow Path) have been presented.
상기 전자의 실용신안등록은 돌출봉은 외측면에 안내홈이 형성된 장착구의 삽입공에 삽입되고 안내홈에는 일측면에 경사면을 형성한 누름편을 스프링으로 탄설하여 고정판을 케이싱과 결합볼트로 고정하며 누름편은 돌출봉 측에 경사면을 형성하여 장착구에 형성된 안내홈을 따라 슬라이딩 되도록 하되 압입시에 돌출봉을 내측으로 복귀되게 한 구조이다.The utility model registration of the former is a protrusion rod is inserted into the insertion hole of the mounting hole formed with a guide groove on the outer side, and the guide groove is pressed with a spring to form the inclined surface on one side to fix the fixing plate with the casing and the coupling bolt and press The piece has a structure in which the inclined surface is formed on the side of the protruding rod so as to slide along the guide groove formed in the mounting hole, but the protruded rod is returned to the inside when press-fitted.
상기 후자의 특허등록은 가스유입로와 가스배출로를 일직선상으로 배치하고 상기 가스유입로의 외측단에는 주입밸브가 내장된 주입구를 형성하며 내측단에는 몸체의 측부로부터 삽입되는 리셋버튼을 갖는 차폐수단(리셋가이드,판스프링,차단밸브)을 형성하며 상기 가스배출로의 단부에는 조절밸브를 결합 형성하고 하측에는 직교상의 배출구를 형성하여 주입구로부터 가스유입로 내측으로 공급되는 가스는 가스실과 관통되게 한 유입공의 내측으로 공급되고 그 가스실 내부의 가스는 배출공을 통해 가스배출로로 공급되어 그 배출구를 통해 정압공급되게 한 구조이다.The latter patent registration has a gas inlet and a gas outlet in a straight line, the outer end of the gas inlet to form an injection port with a built-in injection valve, the inner end of the shield having a reset button inserted from the side of the body A means (reset guide, leaf spring, shut-off valve) is formed, and a control valve is formed at the end of the gas discharge path and an orthogonal discharge port is formed at the lower side so that the gas supplied from the inlet to the gas inlet passage is penetrated with the gas chamber. It is supplied to the inside of one inlet hole and the gas inside the gas chamber is supplied to the gas discharge path through the discharge hole so that the constant pressure supply through the outlet.
상기 전자는 밸브샤프트의 작용으로 가스콕크 내에서 가스유로를 차단하고 사용자 수동으로 누름편을 복귀시켜 재사용할 수 있게 하였으나 상기 가스콕크에 적용되는 안전수단은 기존의 유로와 직각으로 교차되는 신규의 유로를 추가로 적용하므로 제작상의 문제와 금형비,중량 및 부피가 증대되는 단점이 있고 또한 가스유로를 차단시킨 후 재사용시에 사용자가 수작업으로 누름편을 복귀시켜야하는 사용 상의 문제점이 있었다.The electrons block the gas flow path in the gas cock under the action of the valve shaft and allow the user to manually return the press piece for reuse. However, the safety means applied to the gas cock is a new flow path crossing the existing flow path at right angles. There is a drawback in that the production problem and mold cost, weight and volume increases because it is additionally applied, there is also a problem in the use of the user to manually return the pressing piece when reusing the gas flow after reuse.
또한 상기 후자는 가스유입로와 가스배출로를 단일 직선형태로 단순화시켜 제조상의 장점과 과압발생 시 가스유입로 내측단에서 유로를 자동으로 차단시키는 차폐수단이 형성되어 안정성을 확보하고 단일 유로로 정압공급과 과압차단이 이루어지나 전자와 동일하게 리셋버튼을 사용자가 수작업으로 작동시켜 복귀시켜야 하는 문제가 있고 상기 리셋시키기 위한 힘이 약 4Kg(차단밸브의 면적이 5.5㎠)이여서 수작업 또는 기구를 이용한 작동에 문제점이 있었다.In addition, the latter simplifies the gas inlet and the gas outlet into a single straight form, so that a shielding means for automatically blocking the flow path at the inner end of the gas inflow path when the overpressure occurs is formed to secure stability and positive pressure into a single flow path. Supply and overpressure cut off, but same as the former, there is a problem that the user has to reset the reset button by manual operation, and the force for resetting is about 4Kg (the area of the shutoff valve is 5.5cm2). There was a problem.
상기 전자와 후자 모두 과압사고 시 작동된 차폐수단을 원위치로 복귀시켜 유로를 개방시키는 것은 수작업에 의존하고 있는 실정이고 이를 개선하기 위해서는 가스안전공사의 법규(제조기준 구조8항)에 정해진 방식 즉,차단식의 안전장치는 작동 후 자동으로 복귀되어서는 안 되는 구조로 제조할 것을 규정하고 있어 상기 법규에 부응하는 구조의 복귀장치가 요구되고 있다. In both the former and the latter, the opening of the flow path by returning the shielding means operated in the overpressure accident to its original position is dependent on manual operation. In order to improve this, the method defined in the Gas Safety Corporation's regulations (Article 8 of the Manufacturing Standard Structure), Shut-off safety devices stipulate that they should be manufactured in a structure that should not be automatically returned after operation, so that a return device that conforms to the law is required.

이와 같이 된 본 발명은 액화 부탄가스를 연료로 사용하는 휴대용 가스레인지의 과압으로 인한 사고발생 시 3단 구조의 차단밸브에 의하여 유로를 차단시켜 위험을 방지하고 유로차단 후 재사용 시 손잡이 노브에 설치된 캠으로 리턴레버가 리셋버튼을 눌러서 유로를 개방시키는 반자동방식의 휴대용 가스레인지의 과압 방지를 위한 유로차단 및 복귀장치를 갖춘 안전조정기를 제공하기 위한 것이다.The present invention as described above prevents the risk by blocking the flow path by the three-stage shut-off valve in the event of an accident due to overpressure of the portable gas range using liquefied butane gas as a fuel cam installed on the knob knob when the flow path is blocked and reused Therefore, the return lever is to provide a safety regulator with a flow path blocking and return device for preventing the overpressure of the semi-automatic portable gas range by pressing the reset button to open the flow path.
도 1,2 에 도시된 바와 같이 휴대용 전자레인지의 안전콕크에서 과압발생 시 유로를 차단하는 장치와 유로 차단 후 재사용을 위한 복귀장치로 구성된다.As shown in Figures 1 and 2, the safety cock of the portable microwave oven is composed of a device for blocking the flow path when the overpressure occurs and the return device for reuse after blocking the flow path.
과압발생 시 유로를 차단하는 차폐수단(40)은 몸체(10)의 측부로부터 삽입되는 고정체(42)에 스프링(43)의 탄발력에 의해 설치된 리셋버튼(41)과 가스유입로(20)의 내측에 삽입되는 리셋가이드(44),판스프링(45) 및 차단밸브(46)로 이루어진다.The shielding means 40 for blocking the flow path when the overpressure occurs is the reset button 41 and the gas inflow path 20 installed by the elastic force of the spring 43 to the fixed body 42 inserted from the side of the body 10 It is composed of a reset guide 44, the leaf spring 45 and the shut-off valve 46 is inserted into the inside.
상기 차단밸브(46)는 밸브부싱(46a),밸브샤프트(46b) 및 밸브몸체(46c)의 3단구조로 구성되고 밸브몸체(46c)의 내부로 밸브샤프트(46b)를 삽입시켜 밸브샤프트(46b)의 선단에 밸브부싱(46a)이 결합되는 구조이다.The shut-off valve 46 is composed of a three-stage structure of the valve bushing 46a, the valve shaft 46b, and the valve body 46c, and inserts the valve shaft 46b into the valve body 46c to form a valve shaft ( The valve bushing 46a is coupled to the tip of 46b).
상기 3단 구조로 형성되는 차단밸브(46)의 면적은 2.25㎠으로 하는 것이 바람직하고 상기한 구조로 형성되어 과압발생 시 유로를 차단하는 리셋버튼(41)을 1kg의 힘으로 작동시킬 수 있게 하여 차단된 유로를 용이하게 개방시킬 수 있게 하였다. The area of the shut-off valve 46 formed in the three-stage structure is preferably 2.25 cm 2 and is formed in the above-described structure so that the reset button 41 which cuts off the flow path when an overpressure occurs can be operated with a force of 1 kg. The blocked flow path can be easily opened.
과압이 발생하여 유로를 차단하는 작동구조는 가스유입로(20)를 통하여 과도한 압력의 가스가 유입되면 그 가스압은 유입공(15)을 통하여 가스실(11)로 공급하지 못하게 밸브부싱(46a),밸브샤프트(46b) 및 밸브몸체(46c)로 구성된 차단밸브(46)가 밀려나게 되고 이로 인한 차단밸브(46)의 밸브부싱(46a) 외면이 유입공(15)을 막아 더 이상 가스실(11) 내부로 과압의 가스가 공급되지 않게 되는 것이다.The operation structure for blocking the flow path due to the overpressure is generated when the gas of excessive pressure flows through the gas inlet passage 20 so that the gas pressure is not supplied to the gas chamber 11 through the inlet hole 15. The shutoff valve 46 composed of the valve shaft 46b and the valve body 46c is pushed out, and thus the outer surface of the valve bushing 46a of the shutoff valve 46 blocks the inlet hole 15 so that the gas chamber 11 is no longer provided. Overpressure gas is not supplied inside.
이때 밀려나게 된 차단밸브(46)의 밸브부싱(46a)이 원형 곡면체인 판스프링(45)을 반대로 밀어 리셋가이드(44)가 조절밸브(31) 측으로 밀려나면서 리셋버튼(41)의 경사홈부(47)에 걸려 3단 구조의 차단밸브(46)가 밀려난 상태를 유지하게 되어 가스가 공급되는 유로를 계속 차단하는 상태를 유지한다.At this time, the valve bushing 46a of the shut-off valve 46 pushed out pushes the leaf spring 45, which is a circular curved body, and the reset guide 44 is pushed toward the control valve 31, and the inclined groove portion of the reset button 41 47, the three-stage shut-off valve 46 is kept pushed out to keep the flow path to the gas supply.
상기와 같이 가스의 과압으로 인하여 유로가 차단되면 검사 후 재사용을 위하여 유로를 개방시키기 위한 작동은 리셋버튼(41)을 몸체(10)방향으로 눌러 차폐상태를 해제시키면되는 것으로 그 작동은 본체를 개방할 필요없이 간단하게 손잡이 노브(50)를 원위치시킨 후 다시 회전시키면 되는 것이다.(점화작동)When the flow path is blocked due to the overpressure of the gas as described above, the operation for opening the flow path for reuse after inspection is to release the shielding state by pressing the reset button 41 toward the body 10 to open the body. You do not need to simply turn the knob 50 to its original position and then rotate it again.
차단된 유로의 복귀장치는 손잡이 노브(50)의 내측 중앙에 일측으로 돌출되는 캠(51)을 형성하고 리셋버튼(41)과 캠(51) 사이의 몸체(10)에 리턴레버(60)을 힌지 구조로 설치하여 리턴레버(60)의 일측은 리셋버튼(41)의 후단에 위치하게 하고 타측은 손잡이 노브(50)의 회전작동 시 내측에 돌설된 캠(51)에 접촉되는 부위에 위치하게 구성한다.The return device of the blocked flow path forms a cam 51 protruding to one side in the inner center of the knob knob 50, and returns the return lever 60 to the body 10 between the reset button 41 and the cam 51. It is installed in the hinge structure so that one side of the return lever 60 is located at the rear end of the reset button 41, and the other side is located at the part which is in contact with the cam 51 protruding inward during the rotation operation of the knob knob 50. Configure.
