Air-gas linkage device

Abstract

The invention discloses an air-gas linkage device comprising a kindling valve, a main fire valve, a main fire valve limiting device, a gas pipe, a kindling flame gas pipe, a normal combustion gas pipe, a microswitch igniter, a microswitch igniter knob, a stroke switch swing arm, a cam, a limiting connecting rod, a kindling valve hanging plate, a main fire valve hanging plate, a vertical shaft, a metal wire, a metal wire guide groove and a fixing plate. The cam is connected to the kindling valve hanging plate, one end of the stroke switch swing arm and one end of the limiting connecting rod ina pivoted mode, and the other end of the limiting connecting rod is connected with the main fire valve limiting device in a pivoted mode. The main fire valve limiting device abuts against the main fire valve hanging plate when the kindling valve is in a closed state. The kindling valve hanging plate is mounted below the kindling valve and rotates along with rotation of the kindling valve. The mainfire valve hanging plate is mounted below the main fire valve and rotates along with rotation of the main fire valve. According to the air-gas linkage device, the operation that a kindling is ignitedfirstly and then gas is released is ensured, operation is convenient, operating is safe and reliable, and the gas and combustion air work in a linkage mode.

Description

technical field [0001] The invention relates to the technical field of gas cookers, in particular to an air-air linkage device. Background technique [0002] With the development of science and the progress of society, modern equipment is gradually entering people's lives. Modern equipment not only makes people's life more convenient, but also promotes the progress of human society. Most of the wind and gas linkage switch systems currently used in gas stoves are chain-driven connecting rods, and the damper is opened to the size of the gas valve to realize air supply and combustion. Because most of the chains are made of iron metal, they are easy to rust, and the installation is time-consuming and difficult to maintain. The gas regulating valve and the kindling valve are installed side by side on the main pipeline of the gas stove. When in use, the kindling gas supply and ignition are not completed synchronously. If the operator violates the principle of "fire first and then...

AI Technical Summary

Problems solved by technology

Since most of the chains are made of iron metal, they are easy to rust, and the installation is time-consuming and difficult to maintain

The gas regulating valve and the kindling valve are installed side by side on the main pipeline of the gas stove. When in use, the kindling gas supply and ignition are not completed synchronously. If the operator violates the principle of "fire first and then release gas", an explosion accident will occur

Another hidden danger is that the main fire regulating valve is also prone to false opening. If the main fire valve is opened in advance when the fire is not ignited, a large amount of combustible gas will be put into the furnace, which is very dangerous and prone to deflagration accidents.
