Document Type and Number:
WIPO Patent Application WO/2017/197547
Kind Code:
A1
Abstract:
A universal dual-gas valve used for facilitating the switching and adjustment of two fuel gases, comprising a valve body (1), the valve body (1) being provided therein with an intake passage (4a), a first auxiliary intake passage (3a) and a second auxiliary intake passage (3b), the first auxiliary intake passage (3a) and the second auxiliary intake passage (3b) being communicated by means of a valve port (31); the valve body (1) further being provided therein with an adjustment hole (5), the adjustment hole (5) being internally threaded with an adjustment screw (6), in a state in which the adjustment screw (6) may screw downward to the lowest point in a tightening direction, the fuel gas flow passing through the valve port (31) then being at a minimum; and the adjustment hole (5) being provided therein with a limiting portion (121), in a state in which the adjustment screw (6) may move up in a loosening direction to contact with the limiting portion (121), the fuel gas flow passing through the valve port (31) then being at a maximum. In the state that the adjustment screw (6) moves up to contact with the limiting portion (121), the adjustment screw (6) is blocked from moving further up, at which point it can indicate to the operator that when the fuel gas valve is in this state, the fuel gas flow passing through the valve port is at a maximum, which is suitable for natural gas use.
