Abstract

PURPOSE: To ensure shut-off of gas flow and extinction of gas apparatus upon earthquake or the like, by shutting-off the supply of LPG in the close proximity of a bomb upon earthquake and by providing a shut-off valve capable of discharging residual gas in pipes simultaneously with the shut-off operation of the LPG supply with the assist of a pressure reducing mechanism internally incorporated.
CONSTITUTION: When an earthquake occurs or gas flow is excessive due to a rubber hose coming off during the supply of gas in the direction of arrows, a ball valve 15 rolles on a spherical valve seat 16, and is attracted by a magnet 30 at the top of the valve seat 16. Thus, the supply of gas is shut-off, and also a spring 26 depresses a piston 10 through an indicator shaft 4 so that residual gas in gas pipes is discharged upwards through a gap defined between a cylinder 25 and a piston 10 which form a pressure reducing mechanism, flowing along the indicator shaft 4, and is finally vented from the top. With this arrangement, gas pressure in the pipes is promptly reduced after the ball valve 15 is attracted by the magnet 30, thereby to extinguish gas apparatus, immediately.
