Multi-gear flow dividing device and water heater

Abstract

The invention discloses a multi-gear flow dividing device and water heater. The water heater comprises the multi-gear flow dividing device; the multi-gear flow dividing device comprises a flow dividing pipe, a plurality of piston pieces and a switching piece; the flow dividing pipe is provided with a main channel and a plurality of output channels communicated with the main channel; the piston pieces are connected to the flow dividing pipe, and the multiple piston pieces correspond to the output channels; the multiple piston pieces correspond to the multiple output channels in a one-to-one mode; each piston piece can make the corresponding output channel disconnected from the main channel; the switching piece is connected to the flow dividing pipe; the switching piece can drive the piston pieces to move and can change the number of the driven piston pieces, so that the output channels with the corresponding number are communicated with the main channel. By changing the number of the piston pieces driven by the switching piece, the number of the output channels communicated with the main channel is changed; and gas on-off control over a single output channel and progressive increase and progressive decrease change of the number of the output channels for outputting gas are achieved.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to a multi-gear diverter device and a water heater. Background technique [0002] Existing gas water heaters generally include a fire row burner and a manifold assembly connected to the fire row burner. The fire row burner has multiple fire rows, and the manifold assembly is provided with a solenoid valve and a plurality of fire manifolds There are a plurality of output channels corresponding to each other, and the on-off gas of the output channels is controlled by the solenoid valve, so as to control the on-off of the gas output to the fire row. For the existing shunt pipe assembly, a solenoid valve on it generally controls the gas on-off of two to three output channels at the same time, so that each solenoid valve controls two to three fire rows, such a setting method It is impossible to realize the gas on-off control of a single output channel or the increasing and decreas...

AI Technical Summary

Problems solved by technology

For the existing shunt pipe assembly, a solenoid valve on it generally controls the gas on-off of two to three output channels at the same time, so that each solenoid valve corresponds to control two to three fire rows, such a setting method It is impossible to realize the gas on-off control of a single output channel or the increasing and decreasing changes in the number of output channels of the output gas. The firepower of the burner varies greatly and cannot better adapt to the needs of different users; Separately control the gas on-off of an output channel, such a setting method will increase the number of solenoid valves, and each solenoid valve needs to be equipped with a corresponding control module, which increases the complexity of the system and leads to an increase in production costs, which is inconvenient production application
