Title:
GAS VALVE CAPABLE OF ACHIEVING SYNCHRONOUS CHANGE IN BOTH OUTER-RING FIRE AND INNER-RING FIRE
Document Type and Number:
WIPO Patent Application WO/2017/156650
Kind Code:
A1
Abstract:
A gas valve capable of achieving a synchronous change in both outer-ring fire and inner-ring fire, comprising a valve body (1) and a valve core (2). A ventilation chamber (4) is provided on the lower part of the valve core (2), and outer-ring fire holes (3) are provided on the side wall of the ventilation chamber (4). An inner-ring fire groove (5) is provided on the outer peripheral wall of the valve core (2) and the inner-ring fire groove (5) is in communication with an inner-ring nozzle gas outlet passage (13). A transition airway (14) and an auxiliary airway (15) are provided inside the valve body (1). The transition airway (14) branches into two paths, one connecting the outer-ring fire holes (3) to an outer-ring nozzle gas outlet passage (12), and the other connecting the outer-ring fire holes (3) to the inner-ring fire groove (5). The auxiliary airway (15) is in communication with the inner-ring nozzle gas outlet passage (13). Gas, in the gas valve, first passes through the outer-ring fire holes, the gas outlet amount of which is adjusted by rotating the valve core, and then is re-distributed. Therefore, as long as the amount of gas passing through the outer-ring fire holes is changed, the outlet amount of gas from the outer-ring nozzle gas outlet passage and from the inner-ring nozzle gas outlet passage is synchronously changed.
