Fuel gas distributor and fuel gas distribution method of water heater

Abstract

The invention discloses a fuel gas distributor and a fuel gas distribution method of a water heater. The fuel gas distributor comprises a front pipe body, conical valves and a movement mechanism. The front pipe body is provided with a distribution cavity which is provided with an air inlet and a plurality of air outlet nozzles. The conical valves are connected with the air outlet nozzles in one-to-one correspondence. The conical valves are provided with rack parts, the movement mechanism comprises gears meshing with the rack parts in a one-to-one correspondence mode, and the movement mechanism is arranged to drive the gears to rotate to drive the conical valves to move in a second linear direction so as to control the air outlet sectional area of the air outlet nozzles. According to the fuel gas distribution method, the pressure value of fuel gas at the input end of a proportional valve is obtained, the pressure value is compared with the preset pressure interval, the pressure interval where the pressure value is located is judged, the type of the fuel gas is recognized accordingly, the initial value of the corresponding gas outlet sectional area is called to be matched with the type of the fuel gas, and then a normal combustion mode is started, so that the effect that the fuel gas distributor automatically adapts to gas types is achieved.

Description

technical field [0001] The invention relates to a gas distribution method for a gas distributor and a water heater. Background technique [0002] Gas sources for gas water heaters are divided into artificial gas, natural gas and liquefied petroleum gas. my country's gas supply field started relatively late, and all three gas sources are currently in use, resulting in the need to replace different distributors when switching the gas source of the gas water heater, requiring professional personnel to carry out door-to-door operations, and the gas water heater needs to be turned on during the operation It is time-consuming and labor-intensive to replace the dispenser of the face mask. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas distribution method for a gas distributor and a water heater in order to overcome the above-mentioned defects in the prior art. [0004] The present invention solves the above tech...
