SEPARATE FLOW PATH TYPE OF GAS-AIR MIXING DEVICE |
摘要 |
According to the present invention, a gas-air mixing device used in a gas boiler includes: a gas supply tube branched into a first gas flow path and a second gas flow path; an air supply tube branched into a first air flow path and a second air flow path by means of an air-flow-path branching apparatus; a pressure valve which is connected to the inlet side of the gas supply tube in order to adjust the supply rate of gas being supplied to the gas supply tube; and a drive unit in which two valve bodies are connected to a rod that moves vertically up and down due to the magnetic force of an electromagnet; and the air-flow-path branching apparatus is formed to have a slot that connects to either the first air flow path or the second air flow path, and has a joining part which the rod can pass through in a position corresponding to the slot. |
