Title:
LPG (LIQUEFIED PETROLEUM GAS) OVERFLOW BLOCKING APPARATUS
Document Type and Number:
WIPO Patent Application WO2000009918
Kind Code:
A3
Abstract:
An LPG overflow blocking apparatus, having a valve body (110) with a gas inlet/outlet (110A), a gas passage hole (110B) and a gas outlet (110C), and a valve handle (120) for opening and shutting the gas passage hole (110A) of the valve body (110), is disclosed which includes: a valve means being operated upward according to a difference pressure when the pressure difference is caused inside the gas passage hole (110B) when an overflow occurs at the gas outlet (110C), and blocking the gas passage hole (110B); two valve axis guide members (132, 142) being disposed at the gas inlet/outlet (110A) of the valve body (110) for supportably guiding the valve means in its upward operation; and an elastic support means (180) being mounted at the valve axis guide member (132) for elastically supporting the valve means. With this construction, when the gas is discharged as overflow, it is quickly and safely blocked, thereby preventing a possible big gas incident.
