Abstract

PURPOSE: A safety gas valve is provided to normally supply gas at a shock of a small amount, and to re-supply gas after eliminating gas blocking elements regardless of no power supply. CONSTITUTION: In case of the leakage of gas from an outlet gas pipe(2), the pressure of the outlet gas pipe is rapidly reduced. Thus, a weight(40) is elevated to insert an upper plugging part into a gas outlet. An O-ring(45) blocks an inlet of the gas outlet to cut off gas supply to the outlet gas pipe. In case of forming an operation rod(74) on the upper part of the weight, the operation rod is inserted into a releasing valve(80). After replacing a gas pipe, an electromagnet(65) is operated to pull the weight downward, then gas is normally supplied. In case of power failure, a handle of the releasing valve is rotated to rotate a cam. The front end of the cam pushes the operation rod for lowering the operation rod. Thus, the weight is lowered for supplying gas.

Description

가스 안전 밸브{Safety gas valve}Safety gas valve

본 발명은 가스 안전밸브에 관한 것으로, 취사 또는 난방용 연료인 도시가스또는 LPG 가스의 누출과 가스관 파열을 감지하여 자동적으로 가스공급을 차단시킴으로써 가스사고를 미연에 방지해주고, 가스사고 요인 제거시 정상적으로 가스를 재공급시켜 주는 한편 정전시에는 가스공급이 가능하도록 한 것이다.The present invention relates to a gas safety valve, and detects the leakage of gas or LPG gas, which is cooking or heating fuel, and gas pipe rupture to automatically shut off the gas supply to prevent gas accidents in advance, and to remove the gas accident factors normally. While resupply, the gas can be supplied in case of power failure.

기존의 가스안전밸브는 본 출원인에 의해 국내에 실용신안등록출원 1999-0013896호로 출원된 가스안전밸브가 있다.Existing gas safety valve is a gas safety valve filed in the Utility Model Registration Application No. 1999-0013896 in Korea by the applicant.

본출원인에 의해 선출원된 가스안전밸브는 가정용 가스의 누출 또는 가스배관 파열시 가스관 내부의 압력변화를 이용하여 가스공급을 자동차단시키는 것이나,가스관 파열이나 가스누출시 추가 상부로 이송되어 가스출구를 막아 가스사고를 방지하는 안전조처를 취한 후, 가스를 재공급시킬때는 전자석을 자동시켜야 하나, 전원공급이 차단되어 있는 상태에서는 전자석의 작동이 차단되어 가스공급을 재개시킬 수 없으며, 특히 가스공급상태에서 약간의 외부충격이 가해질 경우 추가 상부로 이동되어 가스공급이 차단되는 문제점이 있다.The gas safety valve pre- filed by the present applicant is to shut off the gas supply by using the pressure change inside the gas pipe when the gas leaks or the gas pipe is ruptured.However, in case of gas pipe rupture or gas leakage, the gas safety valve is transferred to the upper part to block the gas outlet. After the safety measures are taken to prevent accidents, the electromagnets should be automatically reactivated when the gas is supplied again, but the operation of the electromagnets is cut off when the power supply is cut off. When an external shock is applied, there is a problem that the gas supply is blocked by moving to an upper portion.

즉 선출원된 가스안전밸브는 무시해도 좋을만한 충격에도 가스가 차단될 우려가 있으며, 가스차단 후 차단원인을 제거한뒤 반드시 전기공급이 된 상태에서만가스를 재공급시킬 수 있게 된다.In other words, the gas safety valves that have been pre- filed may be shut off even in a negligible impact, and after the gas is cut off, the gas may be supplied again only after the electricity is supplied.

본 발명은 무시해도 좋은 충격이 있을때에는 가스를 차단시키지 않고 정상적으로 가스공급이 이루어 지도록 하고, 가스공급이 차단된 후 차단요인이 해소된 상태에서는 전기공급이 되지 않더라도 가스를 재공급시킬 수 있도록 한 것으로,In the present invention, when there is a shock that can be ignored, the gas is normally supplied without blocking the gas, and after the gas supply is cut off, the gas can be supplied again even if electricity is not supplied when the blocking factor is eliminated. ,

사소한 충격을 무시하기 위하여는 가스출구를 막아주는 추가 가스공급상태에서 서서히 회전되게 하므로써 사소한 충격에 의해서는 가스출구를 차단하지 않도록하고,In order to ignore minor impacts, do not block the gas outlets due to minor impacts by rotating slowly in the additional gas supply state which blocks the gas outlets.

전기공급없이 가스를 재공급하기 위해서는 상부로 이동된 추를 강제로 하부로 밀어내는 해제밸브를 작동시킴으로써 가스차단원인 제거 후 전기공급이 없더라도 가스재공급이 가능토록 한 것이다.In order to supply gas without electricity supply, it is possible to supply gas even if there is no electricity supply after removing the cause of gas shutoff by operating a release valve forcibly pushing the weight moved upward.

본 발명은 외통에 결합된 이송통의 내부에서 가스압에 의해 추를 상하 이동시켜 가스입구와 가스출구를 막아주며 이송통의 상부와 외통의 하부에 전자석이 구비된 가스안전밸브에 있어서,The present invention is to prevent the gas inlet and the gas outlet by moving the weight up and down by the gas pressure inside the transfer cylinder coupled to the outer cylinder, and in the gas safety valve provided with an electromagnet at the upper portion and the lower portion of the outer cylinder,

추의 하부에 하부날개를 형성시키되 하부날개의 외측으로 나선형홈을 형성시키고, 추의 상막음부가 가스출구쪽으로 길게 삽입되게 하되 상부 상막음부는 해제밸브의 작동시 하부로 밀려나게 하므로써 이루어 진다.The lower wing is formed on the lower part of the weight, but the spiral groove is formed outside the lower wing, and the upper film part of the weight is inserted into the gas outlet long, but the upper upper film part is made to be pushed down when the release valve is operated.

추(40)는 외측으로 다수의 구멍(42)이 뚤린 날개(41)가 형성되고, 상부에는 가스출구(34)에 삽입되는 상막음부(43)를 형성시키는 한편 하부에는 가스입구(52)로 삽입되는 하막음부(44)를 형성시키며 상측으로 가스출구(34)를 막아주는 오링(45)이 끼워지게 구성된다.The weight 40 has wings 41 with a plurality of holes 42 outwardly formed therein, and an upper portion of the upper portion 43 is inserted into the gas outlet 34 at the upper portion thereof, while the gas inlet 52 is formed at the lower portion thereof. O-ring 45 is formed to block the gas outlet 34 to the upper side forming the lower portion 44 is inserted.

상기 추(40)는 이송통(30)내부에 삽입되어 가스압에 의해 상,하이송되며 날개(41)는 이송통(30)내부에서 추(40)의 좌,우움직임을 잡아주고 가스입구(52)로 유입된 가스는 구멍(42)을 통하여 가스출구(34)로 배출된다.The weight 40 is inserted into the transfer cylinder 30, and is moved up and down by gas pressure, and the blade 41 holds the left and right movements of the weight 40 in the transfer cylinder 30, and the gas inlet ( The gas introduced into the 52 is discharged to the gas outlet 34 through the hole 42.

이송통(30)은 외통(50)상부에 걸쳐지는 걸림턱(31)이 형성되고 걸림턱(31)상부에는 나사부를 형성시키며 하부에는 오링(33)을 끼운다.Transfer barrel 30 has a locking jaw 31 is formed over the outer cylinder 50 is formed, the upper portion of the locking jaw 31 to form a screw portion and the O-ring 33 is fitted in the lower portion.

이송통(30)의 오링(33)은 이송통(30)을 외통(50)내부에 삽입시킬 때 이송통(30)과 외통(50)과의 기밀유지를 위해서 사용되며 외통(50)의 상측에는 나사부가 형성되고 하부에는 가스입구(52)가 형성된다.The o-ring 33 of the transfer cylinder 30 is used for maintaining the airtightness between the transfer cylinder 30 and the outer cylinder 50 when the transfer cylinder 30 is inserted into the outer cylinder 50 and is located above the outer cylinder 50. The screw portion is formed and the gas inlet 52 is formed in the lower portion.

외통(50)의 나사부에는 상부 고정통(20)의 나사부가 결합되고 상부고정통(20)의 고정턱은 이송통(30)의 걸림턱(31)상부에 걸려진다.The threaded portion of the upper fixing cylinder 20 is coupled to the threaded portion of the outer cylinder 50, and the fixing jaw of the upper fixing cylinder 20 is caught on the locking jaw 31 of the transfer cylinder 30.

상부 고정통(20)외측에는 너트(10)를 끼워 이송통(30)의 나사부에 너트(10)가 결합되게 고정시키며, 이송통(30)의 상부에는 전자석(61)이 설치되고 외통(50)의 하부에도 전자석(65)이 설치되게 구성되어진다.The nut 10 is fitted to the outside of the upper fixing cylinder 20 to fix the nut 10 to be coupled to the threaded portion of the transfer cylinder 30, and an electromagnet 61 is installed on the upper portion of the transfer cylinder 30, and the outer cylinder 50 is fixed. Electromagnet 65 is also provided in the lower part of the).

이러한 구성의 기존 가스안전밸브는 외통(50)의 가스입구(52)에 입구밸브(3)를 매개로 하여 입구가스관(1)을 연결하고, 이송통(30)의 가스출구(34)에 출구밸브(4)를 매개로 하여 출구가스관(2)을 연결하며, 추(40)가 도면표시와 같이 세워질 수 있도록 설치한다.The existing gas safety valve having such a configuration connects the inlet gas pipe 1 to the gas inlet 52 of the outer cylinder 50 via the inlet valve 3, and the outlet to the gas outlet 34 of the transfer cylinder 30. The outlet gas pipe 2 is connected through the valve 4, and the weight 40 is installed so that the weight 40 can be erected as shown in the drawing.

입구가스관(1)과 출구가스관(2) 사이에 연결된 가스안전밸브에서 입구밸브(3)와 출구밸브(4)를 개방시킨 상태의 정상작동시를 살펴본다.In the gas safety valve connected between the inlet gas pipe (1) and the outlet gas pipe (2) looks at the normal operation of the inlet valve (3) and outlet valve (4) in the open state.

입구가스관(1)으로 공급된 가스는 외통(50)내부의 이송통(30)으로 공급되어추(40)의 날개(41)에 부딪히는 한편 날개(41)에 형성된 구멍(42)을 통하여 출구가스관(2)쪽으로 배출되며, 여기서 추(40)는 가스입구(52)로 공급된 가스가 전량 구멍(42)을 통과하지 못하므로 가스압에 의해 이송통(30)내부에서 위로 올라가게 되고 이에 따라 가스입구(34)는 개방상태를 유지하게 된다.The gas supplied to the inlet gas pipe 1 is supplied to the transfer cylinder 30 inside the outer cylinder 50 to impinge on the blade 41 of the weight 40 while passing through the hole 42 formed in the blade 41. Discharged toward (2), where the weight 40 rises up from the inside of the transfer container 30 by gas pressure because the gas supplied to the gas inlet 52 does not pass through the entire hole 42. The inlet 34 will remain open.

그러나 추(40)가 가스압에 의해 상부로 밀렸더라도 출구가스관(2)내의 압력과 추(40)자체의 무게에 의해 완전히 상승되지 못하고 가스출구(34)가 개방된 상태를 유지하게 된다.However, even if the weight 40 is pushed upward by the gas pressure, the pressure in the outlet gas pipe 2 and the weight of the weight 40 itself are not fully raised and the gas outlet 34 is kept open.

이때 출구가스관(2)에는 조리기 또는 난방기가 연결되어 조리기 또는 난방기를 사용하더라도 출구가스관(2)에는 항시 일정가스압이 걸리게 되며 이로 인하여 추(40)가 완전 상승되지 못하고 중간정도만 상승하게 된다.At this time, even if the cooker or the heater is connected to the outlet gas pipe 2 and the cooker or the heater is used, a constant gas pressure is always applied to the outlet gas pipe 2.

상기된 정상 사용상태에서 출구가스관(2)쪽에서 가스누출이 되거나 가스관이파열되면 입구가스관(1)의 가스압은 그대로 인데 출구가스관(2)의 압력은 급격히 떨어지게 되며, 이로 인하여 추(40)는 급격히 상승되어 상막음부(43)가 가스출구(34)에 삽입되어 오링(45)이 가스출구(34)입구를 막아주므로써 출구가스관(2)으로 가스공급이 되지 않게 된다.When the gas leaks from the outlet gas pipe 2 in the normal use state or the gas pipe is ruptured, the gas pressure of the inlet gas pipe 1 remains as it is, but the pressure of the outlet gas pipe 2 drops sharply, so that the weight 40 suddenly drops. As it is raised, the upper curtain portion 43 is inserted into the gas outlet 34 so that the O-ring 45 blocks the inlet of the gas outlet 34 so that the gas is not supplied to the outlet gas pipe 2.

즉 가스관파열이나 가스누출시 추(40)의 상부압력이 하부압력에 비해 급격히떨어지게 되어 추(40)가 상부로 이송되므로서 가스출구(34)를 막아주어 가스누출 또는 가스관 파열시 사고의 위험을 미리 제거하게 된다.In other words, when the gas pipe rupture or gas leakage, the upper pressure of the weight 40 is sharply dropped compared to the lower pressure, the weight 40 is transferred to the upper part to block the gas outlet 34 to prevent the risk of an accident in case of gas leakage or gas pipe rupture. Will be removed.

가스공급이 중단된 상태에서 누출지점의 보수나 파열된 가스관의 교체후에는전자석(65)을 구동시키면 된다.The electromagnet 65 may be driven after the leak point is repaired or the ruptured gas pipe is replaced while the gas supply is stopped.

그러면 전자석(65)의 자력에 의해 추(40)는 하부로 밀려 처음과 같은 상태가되어 다시 정상적인 가스공급이 가능하다.Then, the weight 40 is pushed downward by the magnetic force of the electromagnet 65 to the same state as the first time, and normal gas supply is possible again.

또한 가스누출사고를 방지하기 위한 또다른 실시예로 이송통(30)의 상측에 가스누출경보기(60)에 의해 작동하는 전자석(61)을 부착시켜 미세한 가스의 누출로추(40)가 상승하지 못해 가스출구(34)를 차단하지 못할 경우 안전밸브 주위의 가스농도를 감지하여 작동하는 가스누출경보기(60)에 의해 동작이 제어되는 전자석(61)이 추(40)를 상측으로 끌어당겨 상막음부(43)와 오링(45)이 가스출구(34)를 차단시켜 가스사고를 예방하게 된다.In addition, as another embodiment for preventing a gas leakage accident by attaching an electromagnet 61 which is operated by the gas leakage alarm 60 on the upper side of the transfer container 30, the leakage path 40 of the fine gas does not rise. If the gas outlet 34 is not blocked, the electromagnet 61 whose motion is controlled by the gas leakage alarm 60 which operates by sensing the gas concentration around the safety valve is pulled up the weight 40 to the upper part of the upper part. 43 and the O-ring 45 blocks the gas outlet 34 to prevent a gas accident.

위와 같은 기존 가스안전밸브에서는 추(40)가 가스압에 의해 떠있는 상태에놓이게 되므로 외부에서 극히 사소한 충격이 가해지면 추(40)가 움직여 이송통(30)내벽과 밀착하는 경우가 발생되고 이때에는 가스가 정상적으로 빠져 나가지 못하고추(40)에 걸리는 가스압이 증가되므로 추(40)가 상승되어 가스출구(34)를 막아주는문제가 발생되고,In the existing gas safety valve as described above, since the weight 40 is in a floating state due to gas pressure, when a slight impact is applied from the outside, the weight 40 moves and comes into close contact with the inner wall of the transfer container 30. Since the gas does not escape normally and the gas pressure applied to the weight 40 is increased, the weight 40 is raised to block the gas outlet 34,

또한 가스사고 복구후에는 반드시 전자석(65)을 작동시켜야 정상적인 가스공급이 가능하나 가스사고 복구 후 정전이 되면 가스를 재공급시킬 수 없는 것이었다.In addition, after the gas accident recovery must operate the electromagnet 65, the normal gas supply is possible, but if the power failure after the gas accident recovery was not able to supply the gas again.

본 발명은 상기된 문제점을 해결하기 위한 것으로 추(40)의 하부에 수개의 나선홈(71)이 형성된 하부날개(70)를 형성시키고, 가스출구(34)에는 해제밸브(80)를 연결하며, 추(40)의 상부에는 추(40)의 상부 이동시 해제밸브(80)위치까지 미치는 작동봉(74)을 설치한다.The present invention is to solve the above problems to form a lower wing 70 formed with a plurality of spiral grooves 71 in the lower portion of the weight 40, connecting the release valve 80 to the gas outlet 34 On top of the weight 40, the operating rod 74 is installed to reach the position of the release valve 80 when the upper portion of the weight 40 is moved.

작동봉(74)의 선단은 라운드지게 하여 해제밸브(80)에서 캠(81)에 의해 밀리게 구성하고, 상기 캠(81)은 스프링(82)에 탄지된 손잡이(83)로 회동가능하게 구성된다.The tip of the operating rod 74 is rounded to be pushed by the cam 81 from the release valve 80, and the cam 81 is configured to be rotatable by the handle 83 held by the spring 82. do.

손잡이(83)는 회전 후 스프링(82)의 탄성력에 의해 원위치되어 진다.The handle 83 is returned to its original position by the elastic force of the spring 82 after rotation.

본 발명의 추(40)에 대한 다른실시예는 도 4 에 도시된 바와 같이 구멍(42)이 형성된 날개(41)와 나선홈(71)이 형성된 하부날개(70) 및 몸체는 합성수지 등으로 제작하여 그 무게를 줄이고 중앙부에 상막음부(43)와 하막음부(44)가 형성된 철심(73)을 고정시켜 구성한다.Another embodiment of the weight 40 of the present invention, as shown in Figure 4, the lower blade 70 and the body formed with the wing 41 and the spiral groove 71 formed with a hole 42 is made of synthetic resin, etc. By reducing the weight and fixing the iron core 73, the upper curtain portion 43 and the lower curtain portion 44 is formed in the center portion.

이러한 추(40)는 철심(73)을 제외하고 합성수지로 제작되어 무게가 적게 나가 적은 가스압에도 쉽게 이동시킬 수 있으며, 철심(73)의 사용으로 전자석(61)(65)에 의한 이동도 가능하다.The weight 40 is made of synthetic resin except for the iron core (73) is less weight and can be easily moved even with less gas pressure, it is also possible to move by the electromagnets 61, 65 by the use of the iron core (73). .

이러한 본 발명의 가스안전밸브에 대하여 상세히 설명하되, 기존 안전밸브와동일한 구성에 대해서는 동일한 도면부호를 부여하고 그에 대한 설명은 생략키로한다.The gas safety valve of the present invention will be described in detail, but the same configuration as the existing safety valve is given the same reference numerals and description thereof will be omitted.

먼저 정상적인 가스공급시를 살펴본다.First, look at the normal gas supply.

이때에는 입구가스관(1)으로 공급된 가스가 추(40)의 하부날개(70)에 형성된나선홈(71)을 타고 배출된 후 추(40)의 날개(41)에 형성된 구멍(42)을 통하여 출구가스관(2)쪽으로 배출된다.At this time, the gas supplied to the inlet gas pipe 1 is discharged through the spiral groove 71 formed in the lower blade 70 of the weight 40, and then the hole 42 formed in the wing 41 of the weight 40 is opened. It is discharged toward the outlet gas pipe (2) through.

따라서 추(40)는 이송통(30) 내부에서 떠있는 상태가 되나 가스가 나선홈(71)을 타고 배출되므로 추(40)는 나선홈(71)방향으로 서서히 회전하게 되며, 추(40)가 회전하면 사소한 외부 충격에 의해 추(40)가 이송통(30) 내벽과 부딪혀 가스배출에 방해가 되므로써 상부로 이송되어 가스출구(34)를 막아 버리는 문제가 없게 된다.Therefore, the weight 40 is in a floating state inside the transfer container 30, but the gas is discharged through the spiral groove 71, the weight 40 is gradually rotated in the direction of the spiral groove 71, the weight 40 When rotated, the weight 40 hits the inner wall of the transfer cylinder 30 by a slight external impact and thus prevents the gas from being discharged to the upper portion so that there is no problem of blocking the gas outlet 34.

즉 추(40)가 회전하면 사소한 외부충격에 의하여 가스공급이 차단되는 일 없이 정상적인 가스공급이 가능하다.That is, when the weight 40 rotates, normal gas supply is possible without the gas supply being blocked by a slight external shock.

이상태에서 출구가스관(2)에서 가스누출이 되거나 가스관이 파열된 상태를 살펴본다.In this state, the gas leaks from the outlet gas pipe 2 or the gas pipe is ruptured.

이때에는 입구가스관(1)의 가스압은 그대로 인데 출구가스관(2)의 압력은 급격히 감소되며 이로 인하여 추(40)는 상승되어 상막음부(43)가 가스출구(34)의 내측에 삽입되는 한편 오링(45)이 가스출구(34)입구를 막아주어 출구가스관(2)으로 가스공급이 되지 않게 한다.At this time, the gas pressure of the inlet gas pipe 1 remains as it is, but the pressure of the outlet gas pipe 2 decreases rapidly, and as a result, the weight 40 is raised so that the upper curtain portion 43 is inserted into the gas outlet 34 while the O-ring. (45) blocks the inlet of the gas outlet (34) so that no gas is supplied to the outlet gas pipe (2).

즉 가스관파열이나 가스누출시 추(40)의 상부압력이 하부압력에 비해 급격히떨어지게 되어 추(40)가 상부로 이송되므로서 가스출구(34)를 막아주어 가스누출 또는 가스관 파열시 사고의 위험을 미리 제거하게 된다.In other words, when the gas pipe rupture or gas leakage, the upper pressure of the weight 40 is sharply dropped compared to the lower pressure, the weight 40 is transferred to the upper part to block the gas outlet 34 to prevent the risk of an accident in case of gas leakage or gas pipe rupture. Will be removed.

한편 추(40)의 상부에 작동봉(74)이 형성되어 있는 경우 상기 작동봉(74)은해제밸브(80)위치까지 삽입된다.On the other hand, when the operating rod 74 is formed on the upper portion of the weight 40, the operating rod 74 is inserted to the release valve 80 position.

가스공급이 중단된 상태에서 누출지점의 보수나 파손된 가스관의 교체후에는전자석(65)을 작동시켜 추(40)를 하부로 당기도록 한다.After repair of the leak point or replacement of the damaged gas pipe in the state where the gas supply is stopped, the electromagnet 65 is operated to pull the weight 40 downward.

그러면 추(40)는 전자석(65)의 자력에 의해 하부로 이동되고 가스압에 의해완전히 하방이동되지 못하게 되므로 다시 정상적인 가스공급이 가능하게 된다.Then, the weight 40 is moved downward by the magnetic force of the electromagnet 65 and is not completely moved downward by the gas pressure, so that normal gas supply is possible again.

그러나 전기공급이 중단된 상태에서는 전자석(65)의 작동이 중단되어 추(40)를 하향 이동시키지 못하게 된다.However, the operation of the electromagnet 65 is stopped in the state in which the electricity supply is stopped, so that the weight 40 cannot be moved downward.

이때에는 해제밸브(80)의 손잡이(83)를 돌려 캠(81)을 회전시킴으로써 캠(81)의 선단이 작동봉(74)을 밀게 되고 이에 따라 작동봉(74)이 하향이동하면서 추(40)를 하향이동시키게 된다.At this time, by turning the handle 81 of the release valve 80 to rotate the cam 81, the tip of the cam 81 pushes the operating rod 74, and as a result the operating rod 74 is moved downwards, the weight 40 Will move downward).

따라서 가스출구(34)가 열려 정상적인 가스공급이 가능하게 된다.Therefore, the gas outlet 34 is opened to enable normal gas supply.

본 발명은 가정용 가스관에 설치된 가스누출이나 가스관 파열시 급격하게 변화되는 가스압을 이용하여 가스공급을 차단시키도록 하므로서 가스누출이나 가스관파열로 인한 사고를 미연에 방지할 수 있으며, 사소한 외부충격에 의하여 가스공급이 중단되는 경우가 사라지고, 가스 재공급시 전기가 차단된 경우에도 수동으로 가스 재공급이 가능한 것이다.The present invention is to prevent the gas supply by gas leakage or gas pipe burst by using a gas pressure suddenly changed when the gas leak or gas pipe burst installed in the home gas pipe, and the gas supply by a slight external shock This interruption disappears, and even when electricity is cut off when the gas is re-supplied, it is possible to manually re-supply the gas.
