Abstract

The invention provides a gas valve and an anti-backfire stove. Through arranging the gas valve, the air pressure in an air inlet channel is taken as a prerequisite for the passage of gas through a gaschannel; when the air pressure reaches a set value, a first piston and a second piston are driven to move, the air inlet channel and the gas channel are opened, and fresh air blown by an aerating fanand the gas enter a burner to participate in combustion reaction; when the air pressure is too low, the first piston and the second piston reset under the elastic action of a reset spring, the air inlet channel and the gas channel are gradually closed, and in the process, the air pressure in the air inlet channel and the gas pressure in the gas channel are always kept constant, so that the combustion of gas backfire caused by too low air pressure in the air inlet channel is prevented, and a fire is 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] In one aspect, the present invention provides a gas valve, which includes a valve body, a valve cover, a return spring, a first piston and a second piston, the valve cover is arranged on the valve body, and a parallel first piston passage is arranged in the valve body and the second piston channel, the...
