본 고안은 가연성 고압의 가스가 이송되는 가스관의 가스누설 발생시 유로를 즉시 차단하여 안전사고의 위험을 예방하도록 안출한 가스관 안전밸브에 관한 것이다.The present invention relates to a gas pipe safety valve that is designed to prevent the risk of a safety accident by immediately blocking the flow path in the event of gas leakage of the gas pipe to which combustible high pressure gas is transferred.

일반적으로 가스관에는 고압의 가연성 가스가 이송하도록 되어 있는데, 가스관의 부식 또는 파손에 의하여 가스의 누설이 발생하는 경우 폭발 및 화재의 위험이 있게 된다.In general, high-pressure combustible gas is transported to a gas pipe, but when a gas leak occurs due to corrosion or breakage of the gas pipe, there is a risk of explosion and fire.

그런데 가스누설의 발생시 누설위치를 정확하게 판단하기 어렵고, 설사 누설위치를 발견하였더라도 가스의 공급을 즉시 차단할 수 없는 문제점이 있었다.However, it is difficult to accurately determine the leak location when gas leakage occurs, and even if a leak location is found, there is a problem in that gas supply cannot be cut off immediately.

본 고안은 이러한 종래의 문제점을 해결하고자 하는 것으로, 가연성 고압의 가스가 이송되는 가스관의 가스누설 발생시 유로를 즉시 차단하여 안전사고의 위험을 예방하고자 가스관 안전밸브를 제공하는데 그 목적이 있다.The present invention is to solve such a conventional problem, the object of the present invention is to provide a gas pipe safety valve in order to prevent the risk of safety accidents by immediately blocking the flow path in the event of gas leakage of the gas pipe to which the combustible high pressure gas is transferred.

본 고안은 이러한 목적을 달성하기 위하여, 설정된 위치의 양측 가스관의 연결부위마다 설치하여 가스의 이송 및 차단하도록 전기적인 신호에 의하여 개폐되는 솔레노이드밸브와, 솔레노이드밸브를 기준으로 양측 가스관의 전, 후를 연결하여 상호 연통되도록 하는 보조관과, 브조관에 설치되어 양측 가스관의 압력에 의하여 작동되도록 왕복피스톤이 설치된 가스실린더와, 가스실린더의 중간에 왕복피스톤이 위치된 상태에서 양측 가스관의 압력에 의하여 왕복피스톤이 어느 일측으로 이동시 솔레노이드밸브를 차단하도록 가스실린더의 양측에 각각 설치되는 좌,우측스위치로 가스관의 안전밸브를 구성한 것이 본 고안의 특징이다.In order to achieve the above object, the present invention provides a solenoid valve which is installed at each connection part of both gas pipes in a set position, and is opened and closed by electrical signals to transfer and block gas, and the front and rear of both gas pipes based on the solenoid valve. Auxiliary pipes connected to each other to connect with each other, Gas cylinders with reciprocating pistons installed in Bezo pipes to be operated by pressure of both gas pipes, and Reciprocating by pressures of both gas pipes with reciprocating pistons positioned in the middle of the gas cylinders It is a feature of the present invention that the safety valve of the gas pipe is composed of left and right switches respectively installed on both sides of the gas cylinder so as to block the solenoid valve when the piston moves to one side.

이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도면 제1도는 본 고안의 실시예로서, 실정된 위치의 양측 가스관(1)(2)의 연결부위마다 설치하여 가스의 이송 및 차단하도록 전기적인 신호에 의하여 개폐되는 솔레노이드밸브(3)와, 솔레노이드밸브(3)를 기준으로 양측 가스관(1)(2)의 전, 후를 연결하여 상호 연통되도록 하는 보조관(4)과, 보조관(4)에 설치되어 양측 가스관(1)(2)의 압력에 의하여 작동되도록 왕복피스톤(6)이 설치된 가스실린더(5)와, 가스실린더(5)의 중간에 왕복피스톤(6)이 위치된 상태에서 양측 가스관(1)(2)의 압력에 의하여 왕복피스톤(6)이 어느 일측으로 이동시 솔레노이드밸브(3)를 차단하도록 가스실린더(5)의 양측에 각각 설치되는 좌,우측스위치(7)(8)로 가스관의 안전밸브를 구성한다.1 is an embodiment of the present invention, the solenoid valve (3) and the solenoid which is installed by each connection of the gas pipes (1) and (2) of the actual position and opened and closed by an electrical signal to transfer and block the gas Auxiliary pipe (4) for connecting the front and rear of both gas pipes (1) (2) on the basis of the valve (3) to communicate with each other, and is provided in the auxiliary pipe (4) of both gas pipes (1) (2) Reciprocating by the pressure of the gas cylinders (1) and (2) on both sides of the gas cylinder (5) provided with the reciprocating piston (6) and the reciprocating piston (6) in the middle of the gas cylinder (5). The safety valve of the gas pipe is constituted by the left and right switches 7 and 8 respectively provided on both sides of the gas cylinder 5 so that the solenoid valve 3 is blocked when the piston 6 moves to one side.

상기 좌, 우측스위치(7)(8)는 접속스위치, 센서스위치등 어떠한 것을 사용하여도 무방하며, 그 스위치사이의 거리는 설정된 뱀위의 압력차에서 솔레노이드밸브(3)를 작동시키지 않도록 유지한다.The left and right switches 7 and 8 may use any of a connection switch, a sensor switch, and the like, and the distance between the switches is maintained so that the solenoid valve 3 is not operated at the set pressure difference.

그리고, 초기상태(예를들면, 가스관(1)(2)으로 가스가 공급되지 않거나 최초 밸브 설치시, 또는 밸브가 차단되었다가 가스가 재공급될 때)에서 왕복 피스톤(6)이 가스실린더(5)의 중앙부분에 위치하도록 하기 위해 가스실린더(5)의 내부 양측에 동일한 탄성을 갖는 스프링을 각각 설치한다.Then, in the initial state (for example, when gas is not supplied to the gas pipe (1) 2 or when the valve is initially installed or when the gas is supplied again after the valve is shut off), the reciprocating piston (6) is connected to the gas cylinder ( 5) Springs having the same elasticity are installed on both inner sides of the gas cylinder 5 so as to be located at the center of 5).

이때, 왕복피스톤(6)을 탄지하는 스프링의 탄성은 가스압보다 작게하여 가스관(1)(2)의 압력변화 발생시 왕복피스톤(6)이 어느 한쪽으로 움직이는데 영향을 주지 않도록 한다.At this time, the elasticity of the spring supporting the reciprocating piston 6 is smaller than the gas pressure so that the reciprocating piston 6 does not affect the movement of the reciprocating piston 6 to one side when a pressure change of the gas pipes 1 and 2 occurs.

이와같이 구성된 본 고안은, 평상시에는 양측 가스관(1)(2)으로 이송되는 가스의 압력이 일정하게 되므로 솔레노이드밸브(3)를 기준으로 양측 가스관(1)(2)의 전, 후에 연결된 보조관(4)으로 가스압력이 작용하게 되며, 그 가스압은 보조관(4)을 통하여 가스실린더(5)의 왕복피스톤(6)의 양측에 작용하게 되고, 왕복피스톤(6)은 양측 가스압력에 의하여 가스실린더(5)의 중립위치에 머물게 된다.The present invention configured in this way, since the pressure of the gas delivered to both gas pipes (1) (2) is usually constant, the auxiliary pipes connected before and after the gas pipes (1) (2) on the basis of the solenoid valve (3) 4) the gas pressure acts, the gas pressure acts on both sides of the reciprocating piston (6) of the gas cylinder (5) through the auxiliary pipe (4), the reciprocating piston (6) by the gas pressure on both sides It stays in the neutral position of the cylinder 5.

그러나 가스관의 부식 또는 파손에 의하여 어느 일측 가스관(1) 또는(2)에 가스누설이 발생하는 경우 그 가스관(1) 또는 (2)의 압력은 압력 하강이 발생하게 된다.However, when gas leakage occurs in either gas pipe 1 or 2 due to corrosion or breakage of the gas pipe, a pressure drop occurs in the pressure of the gas pipe 1 or 2.

예컨데, 도면상 우측 가스관(2)의 손상으로 가스누설이 발생하는 경우 우측 가스관(2)의 압력은 좌측 가스관(1)의 압력보다 낮으므로 그 압력은 가스관(4)을 통하여 즉시 가스실린더(5)의 왕복피스톤(6)에 전달하게 되고, 왕복피스톤(6)은 평형을 유지하고 있다가 고압측의 가수관(1)의 압력에 의하여 저압측의 가스관(2)측인 도면상 우측으로 이동을 하게 된다. 따라서 왕복피스톤(6)의 우측이동으로 인하여 우측스위치(8)를 동작시키게 되므로 우측스위치(8)는 전원의 도통으로 솔레노이드밸브(3)가 작동하여 우측 가스관(2)의 유로를 차단하게 된다.For example, when gas leakage occurs due to damage of the right gas pipe 2 in the drawing, since the pressure of the right gas pipe 2 is lower than that of the left gas pipe 1, the pressure is immediately passed through the gas pipe 4. Reciprocating piston (6), and the reciprocating piston (6) maintains an equilibrium, and moves to the right in the drawing on the gas pipe (2) side of the low pressure side by the pressure of the gas pipe (1) on the high pressure side. Done. Therefore, since the right switch 8 is operated by the right movement of the reciprocating piston 6, the right switch 8 blocks the flow path of the right gas pipe 2 by operating the solenoid valve 3 by conduction of power.

따라서 좌측 가스관(1)의 가스는 솔레노이드밸브(3)의 차단으로 우측 가스관(2)으로 이송되지 못하므로 안전사고의 위험을 미연에 예방할 수가 있는 것이다.Therefore, the gas in the left gas pipe (1) is not transported to the right gas pipe (2) by the blocking of the solenoid valve (3) can prevent the risk of a safety accident in advance.

그리고 좌, 우측스위치(7)(8)를 중앙통제실에 연결하여 주면 상황실에서 현재 어느 가수관의 누설인지를 즉시 판단할 수 있으므로 가스관의 보수가 편리하게 되는 것이다.If the left and right switches 7 and 8 are connected to the central control room, the repair of the gas pipes is convenient since it is possible to immediately determine which leak pipe is presently leaked from the situation room.

이와같이 본 고안은 가연성 고압의 가스가 이송되는 가스관의 가스누설 발생시 유로를 즉시 차단하여 안전사고의 위험을 예방할 수 있는 효과가 있다.As such, the present invention has the effect of preventing the risk of safety accidents by immediately blocking the flow path when a gas leakage occurs in the gas pipe to which combustible high pressure gas is transferred.
