Abstract

The invention provides a gas valve and an anti-backfire stove. The gas valve and the anti-backfire stove provided by the invention have the beneficial effects that by arrangement of the gas valve, theair pressure in an air inlet channel is used as a precondition for gas to pass through a gas channel, when the air pressure reaches a set value, an air-inlet overturning piece and a gas overturning piece are driven to rotate, the air inlet channel and the gas channel are opened, and fresh air blown by an oxygenation fan and gas enter a burner to participate in burning reaction; when the air pressure is excessively low, the air-inlet overturning piece and the gas overturning piece return under the action of elastic force of spring fasteners, the gas channel is gradually closed, and in the process, constant air pressure in the air inlet channel and constant gas pressure in the gas channel are kept all the time, so that the gas-backfire burning due to excessively-low air pressure in the airinlet channel is prevented and fire disasters are prevented.

Description

technical field [0001] The invention relates to the technical field of cookers, in particular to a gas valve and a backfire prevention cooker. Background technique [0002] Nowadays, many energy-saving cookers, especially semi-premixed commercial energy-saving cookers, when the blower pipeline pressure drops to a certain value, the premixed gas will be backfired and burnt, causing a fire in severe cases. Contents of the invention [0003] In view of this, the present invention proposes a gas valve and an anti-tempering cooker that can effectively prevent gas flashback from developing a fire. [0004] Technical scheme of the present invention is realized like this: [0005] On the one hand, the present invention provides a gas valve, which includes an air inlet channel and a gas channel, the two ends of the air inlet channel are respectively provided with an air inlet and an air outlet, and the two ends of the gas channel are respectively provided with a gas inlet and a ga...
