The washer 70 is installed so that the ball support Teflon ring 13 of the cockcock 10 does not escape, and the indie is melted at the same temperature as the lead 60 to the outside of the connecting pipe 20. It is configured by providing the data (80).
본 발명에서 연결관(20)은 나사부에 의해 볼콕(10)의 일측에 나사 결합되는 것으로, 호스(21)와 연결되게 되며, 연결관(20)의 내측에 결합구(30)와 차단 플레이트(40) 및 탄성 스프링(50)과 밀림방지 와셔(70)가 설치된다.In the present invention, the connection pipe 20 is screwed to one side of the ball cock 10 by the screw, it is to be connected to the hose 21, the coupling port 30 and the blocking plate (inside the connection pipe 20) 40) and the elastic spring 50 and the anti-roll washer 70 is installed.
연결관(20)의 내측에 형성된 가스통로(23)의 입구 쪽에 링 형상의 결합구(30)를 끼우되 상기 결합구(30)의 내경이 가스통로(23)의 내경과 같도록 함으로써 결합구(30)를 끼우더라도 가스통로(23)를 통하여 배출되는 가스의 량에는 변함이 없도록 한다.Insert the ring-shaped coupling port 30 into the inlet side of the gas passage 23 formed inside the connecting pipe 20, so that the inner diameter of the coupling port 30 is the same as the inner diameter of the gas passage 23 Even if the 30 is inserted, the amount of gas discharged through the gas passage 23 does not change.
여기서 결합구(30)의 외측에는 결합돌기(31)를 형성하고, 상기 결합돌기(31)가 끼워지는 결합홈(22)을 연결관(20)에 형성함으로써 결합구(30)가 연결관(20)에 끼워지면 강제로 빼지 않는 한 쉽게 빠지지 않으며, 이로 인하여 가스콕을 세워서 설치하는 경우에도 결합구(30)가 연결관(20)에서 빠지는 경우가 없어지게 된다.Here, the coupling sphere 30 is formed on the outside of the coupling hole 30, and the coupling hole 30 is formed in the coupling pipe 20 through which the coupling protrusion 31 is fitted to the coupling pipe 30. If it is inserted into 20) is not easily pulled out unless it is forcibly pulled out, because of this, even when the gas cock is installed upright, the coupling port 30 is no longer missing from the connecting pipe (20).
상기 결합구(30)의 하측으로는 연결관(20)을 따라 고정대(32)를 형성하여 상기 고정대(32)와 결합구(30)가 연결되는 곳에 힌지(33)(34)를 이용하여 고정 플레이트(40)를 끼운 후 힌지축(35)을 끼워 고정 플레이트(40)가 회동할 수 있도록 하며, 상기 고정 플레이트(40)는 가스통로(23)를 막아주는 쪽으로 이동하는 경우 가스통로(23)를 기밀 되게 막아줄 수 있도록 차단 플레이트(40)와 가스통로(23)가 만나는 부위를 라운드 진 형태로 제작한다. 즉, 차단 플레이트(40)가 세워져 가스통로(23)를 막는 경우 가스 플레이트(40)가 가스통로(23)를 확실히 막아줄 수 있도록 라운드 진 형태를 갖도록 하는 것이다.The lower side of the coupler 30 is formed by using a hinge (33, 34) to form a stand 32 along the connecting pipe 20 to the place where the stand 32 and the coupler 30 is connected. After the plate 40 is fitted, the hinge shaft 35 is fitted to allow the fixing plate 40 to rotate, and the fixing plate 40 moves toward the blocking path of the gas passage 23. The blocking plate 40 and the gas passages 23 are formed in a round jin form to prevent the airtight. That is, when the blocking plate 40 is erected to block the gas passage 23, the gas plate 40 has a rounded shape so as to reliably block the gas passage 23.
상기 고정대(32)에는 고정홀(32a)을 형성하여 초탄성 와이어로 제작되는 탄성 스프링(50)의 일측을 끼운 후 탄성 스프링(50)의 타측은 고정대(32)와 차단 플레이트(40)의 배면을 밀어주도록 하되 연결관(20)의 내측에 납(60)으로 고정되게 한다. 여기서 탄성 스프링(50)은 차단 플레이트(40)를 세워 가스통로(23)를 막아주는 쪽으로 탄성력을 가하도록 하고, 탄성 스프링(50)은 연결관(20)에 납(60)으로 고정됨과 동시에 차단 플레이트(40)의 배면에 고정이 이루어지게 되는 것으로, 납(60)이 녹게 되면 초탄성 와이어로 이루어진 탄성 스프링(50)의 탄성력에 의해 차단 플레이트(40)가 회동하여 가스통로(23)를 막아준 상태를 유지하게 된다.The fixing stand 32 is formed with a fixing hole 32a to insert one side of the elastic spring 50 made of a superelastic wire, and then the other side of the elastic spring 50 is the back of the fixing stand 32 and the blocking plate 40. To push the but to be fixed with lead (60) inside the connector (20). Wherein the elastic spring 50 is to set up the blocking plate 40 to apply an elastic force to block the gas passage 23, the elastic spring 50 is fixed at the same time as the lead (60) to the connecting pipe 20 and blocked When the lead 60 is melted, the blocking plate 40 is rotated by the elastic force of the elastic spring 50 made of the superelastic wire to block the gas passage 23 when the lead 60 is melted. Will remain quasi-state.
상기 탄성 스프링(50)을 연결관(20)에 고정시키되 상기 납(60)은 가스콕으로 일정 온도가 전도되는 경우 녹게 되므로, 화재가 발생하여 납(60)이 녹게 되면 자동적으로 차단 플레이트(40)가 가스통로(23)를 막아주게 되어 가스에 의한 이차사고를 방지하게 된다.The elastic spring 50 is fixed to the connecting pipe 20, but the lead 60 is melted when a predetermined temperature is conducted by a gas cock, so when a fire occurs to lead 60 is automatically cut off the plate (40) ) To block the gas passage 23 to prevent secondary accidents caused by the gas.
또한 가스콕이 세워져 있는 경우 납(60)이 녹게 되면, 녹은 납이 가스통로(23)를 막게 되는 경우가 발생하므로, 납(60)이 녹아내려 차단 플레이트(40)가 회동되는 위치로 흐르지 않돌고 차단봉(61)을 설치하여 납물이 녹아 흐를 때 차단봉(61)이 의해 흐름이 차단되도록 한다. 그리고, 납(60)의 종류를 다양하게 변경시킬 경우 납(60)이 녹는 온도를 달리할 수 있으며, 이렇게 납(60)의 종류가 달라 녹는 온도가 다른 가스콕은 볼콕(10)의 손잡이(12) 색상을 달리하여 구분할 수 있도록 한다.In addition, when the gas cock is upright, when the lead 60 is melted, the molten lead may block the gas passage 23, so that the lead 60 melts and does not flow to the position where the blocking plate 40 is rotated. Turn the blocking rod 61 is turned to block the flow by the blocking rod 61 when the lead melts. In addition, when the lead 60 is changed in various ways, the melting temperature of the lead 60 may be different. Thus, the gas cock different from the melting temperature of the lead 60 is different from the handle of the cockcock 10 ( 12) Different colors can be distinguished.
본 발명에서 연결관(20)의 선단에서 볼콕(10)의 볼지지 테프론링(13)과 밀착되는 곳에는 밀림방지 와셔(70)를 설치하여 볼지지 테프론링(13)이 차단볼(11)의 회전시 연결관(20)쪽으로 밀리게 되는 현상을 방지한다.In the present invention, where the ball support Teflon ring 13 of the ball cock 10 is in close contact with the tip of the connection pipe 20 by installing the anti-shrink washer 70, the ball support Teflon ring 13 is blocked ball 11 To prevent the phenomenon of being pushed toward the connector 20 during rotation.
또한 본 발명은 연결관(20)의 외측으로 인디케이터(80)를 설치하되 상기 인디케이터(80)는 납(60)과 동일한 온도에 녹을 수 있도록 함으로써 인디케이터(80)가 녹아있는 경우 내부의 차단 플레이트(40)가 가스통로(23)를 막고 있는 상태임을 알 수 있다.In addition, the present invention installs the indicator 80 to the outside of the connecting pipe 20, but the indicator 80 is to be melted at the same temperature as the lead 60 by the internal block plate (80) when the melt ( It can be seen that 40 is blocking the gas passage 23.
이러한 본 발명은 화재가 발생되기 전에는 납(60)이 녹는 경우가 없어 차단 플레이트(40)는 납(60)에 의해 연결관(20)에 고정되어 있게 되므로, 가스의 흐름에 하등 영향을 주지 않으며, 특히 결합구(30)가 가스통로(23)에 끼워지더라도 결합구(30)의 내경이 가스통로(23)의 내경과 같도록 함으로써 가스의 흐름에는 전혀 영향을 주지 않게 된다.In the present invention, since the lead 60 does not melt before the fire occurs, the blocking plate 40 is fixed to the connecting pipe 20 by the lead 60, and thus does not affect the flow of gas at all. In particular, even when the coupling port 30 is fitted into the gas passage 23, the inner diameter of the coupling port 30 is equal to the inner diameter of the gas passage 23 so that the flow of gas is not affected at all.
본 발명의 탄성 스프링(50)은 초탄성 와이어로 제작하게 되므로, 장시간 사용하더라도 탄성력을 잃게 되는 경우가 없어지게 되며, 초탄성 와이어는 탄성력을 장기간 유지하는 공지의 와이어이다.Since the elastic spring 50 of the present invention is made of a superelastic wire, the elastic force is not lost even if used for a long time, and the superelastic wire is a known wire that maintains the elastic force for a long time.
가스콕이 설치된 실내에서 화재가 발생하면 열이 전달되게 되고, 화재에 의해 전달되는 열이 납(60)이 녹게 되는 75oC 이상이 되면, 납(60)이 녹게 되고, 납(60)이 녹으면 탄성 스프링(50)이 연결관(20)과의 고정력이 사라지면서 차단 플레이트(40)의 배면을 밀어 차단 플레이트(40)가 힌지축(35)을 중심으로 회동하여 가스통로(23)를 막아주도록 한다.When a fire occurs in a gas cocked room, heat is transferred. When the heat transferred by the fire reaches 75 ° C. or more at which lead 60 is melted, lead 60 is melted, and lead 60 is When melted, the elastic spring 50 loses the fixing force with the connecting pipe 20 and pushes the rear surface of the blocking plate 40 so that the blocking plate 40 rotates around the hinge shaft 35 to open the gas passage 23. Prevent it.
차단 플레이트(40)는 탄성 스프링(50)이 지속적으로 탄성력을 가하게 되므로, 가스통로(23)를 막아준 상태를 유지하게 되고, 차단 플레이트(40)에서 가스통로(23)와 만나는 부위는 라운드 진 형태를 유지하도록 함으로써 가스가 새게 되는 경우를 없애도록 한다.The blocking plate 40 maintains a state of blocking the gas passage 23 because the elastic spring 50 continuously applies an elastic force, and a portion of the blocking plate 40 that meets the gas passage 23 is rounded. Maintaining its shape eliminates gas leaks.

이와 같이 화재가 발생하면 자동적으로 차단 플레이트(40)로 가스통로(23)를 막아주게 되나, 화재가 발생하지 않은 경우에도 과열에 의하여 차단 플레이트(40)가 가스통로(23)를 막아줄 수 있는 것으로, 이러한 경우에는 외부에서 가스 공급이 차단된 것만 확인할 수 있을 뿐, 차단 플레이트(40)가 작동된 상태임을 확인할 수 없다.As such, when the fire occurs, the gas passage 23 is automatically blocked by the blocking plate 40. However, even when the fire does not occur, the blocking plate 40 may block the gas passage 23 due to overheating. In this case, it can only confirm that the gas supply is cut off from the outside, it can not be confirmed that the blocking plate 40 is in operation.
따라서 본 발명에서는 연결관(20)의 외측으로 납(60)과 동일한 재질로 인디케이터(80)를 설치하여 납(60)과 함께 인디케이터(80)도 녹도록 함으로써 사용자는 인디케이터(80)가 녹아있는 경우 차단 플레이트(40)가 작동하여 가스 공급이 차단되어 있음을 쉽게 알 수 있다. 그리고 본 발명은 납(60)의 종류에 따라 작동 온도를 달리 할 수 있는 것으로, 이러한 작동 온도의 다름은 손잡이(12)의 색상을 달리하여 표현하도록 한다.Therefore, in the present invention, by installing the indicator 80 with the same material as the lead 60 to the outside of the connector 20 so that the indicator 80 with the lead 60 also melts the indicator 80 is melted In this case, it is easy to know that the gas supply is blocked by the blocking plate 40 operating. And the present invention can vary the operating temperature depending on the type of lead 60, the difference in the operating temperature is to represent the different color of the handle 12.
한편 본 발명은 결합구(30)가 쉽게 빠지지 않도록 결합돌기(31)를 형성하여 결합홈(22)에 끼워지게 하는 것으로, 결합구(30)가 빠지지 않아 가스콕을 세우거나 뒤집어 설치하는 경우에도 결합구(30)가 연결관(20)의 가스통로(23)에서 빠지지 않게 된다.On the other hand, the present invention is to form a coupling protrusion 31 so that the coupling sphere 30 is not easy to fall into the coupling groove 22, even if the coupling sphere 30 is not pulled out to install or turn over the gas cock Coupling port 30 is not released from the gas passage 23 of the connecting pipe (20).
또한 본 발명에서 차단볼(11)을 지지하는 볼지지 테프론링(13)은 연결관(20)의 입구 직경이 넓을 경우 이탈될 우려가 있으므로, 밀림방지 와셔(70)를 설치하여 볼지지 테프론링(13)을 안정되게 잡아주도록 한다.In addition, in the present invention, since the ball support Teflon ring 13 supporting the blocking ball 11 may be detached when the inlet diameter of the connection pipe 20 is wide, the ball support Teflon ring may be installed by installing the anti-wash washer 70.
