| description | The present invention relates to the multifunctional urgent shutoff safety valve for preventing accidents such as gas explosion, fire, etc. in advance. It is installed at the gas supply path. The spool assembly run by earthquake accelerations in case of an earthquake of stronger than a fixed level shuts off the gas circulation path to stop gas supply, or the spool assembly shuts off the gas circulation path to stop gas supply when an excessive amount of gas is flowed out in a short time due to blowing-out of the rear end pipe of the present valve. In the configuration of the multifunctional urgent shutoff safety valve of the present invention, a permanent magnet, which is mounted on the upper end of the spool assembly installed at the valve room in the main body in the vertical state to pen and close the outlet port, is suspended apart from the bottom surface of the pendulum (acceleration sensor) at a fixed interval, when the valve outlet port is open. If earthquake accelerations of stronger than a fixed level are delivered to the multifunctional urgent shutoff safety valve of the present invention, the pendulum (acceleration sensor) swings or tilts increasing the distance from the spool assembly suspended on the lower surface of the pendulum, the spool assembly is dropped down on the valve seat, and the outlet port is closed thus preventing the flow of gas. |
