Description
Technical Field
The utility model discloses a wall-mounted gas stove, and relates to the technical field of wall-mounted gas stoves.
Background
In areas with poor water quality, water in copper pipes of the wall-mounted furnace corrodes the copper pipes for a long time due to poor water quality and high corrosivity, and particularly at the turning positions and joint welding points of the copper pipes, the copper pipes leak due to long-time corrosion, so that the use is influenced, and the after-sale maintenance rate is high. The existing copper pipe anti-corrosion structure is that a coating or an electroplated layer is formed on the inner wall of a copper pipe, but the processing difficulty is high when the coating and the electroplated layer are formed due to the small aperture of a water pipe, and the processing is troublesome and is not beneficial to production and processing.

FIG. 2 is a view of the copper tube of FIG. 1;
the reference numerals include: 1-heat exchanger, 2-copper tube, 21-nickel coating.
Detailed Description
The present invention will be described in further detail with reference to specific embodiments below:
the utility model provides a gas hanging stove, includes furnace body, controller, fan, combustion chamber, water pump, gas proportional valve and heat exchanger 1, the controller electricity is connected fan, water pump and gas proportional valve, the combustion chamber is established inside the furnace body, heat exchanger 1 is established in the combustion chamber bottom, and heat exchanger 1 includes copper pipe 2, is equipped with nickel coating 21 on the 2 inner walls of copper pipe.
The bottom of the heat exchanger 1 is provided with finned tubes.
The copper pipes 2 are arranged on two sides of the heat exchanger 1.
The thickness of the nickel coating 21 is between 50um and 150 um.
The copper pipe 2 is fixed on the heat exchanger 1 through a connecting part, the top edge of the connecting part is arc-shaped, and the other three edges are straight edges.
The heat exchanger 1 is provided with four connection holes at the front.
To facilitate understanding of the present invention, the operation of the wall-hanging furnace and the process of processing the copper tube 2 will be described.
When the ignition switch of the wall-mounted boiler enters a working state, the fan is started firstly to enable a negative pressure difference to be formed in the combustion chamber, the air pressure switch sends an instruction to the water pump, after the water pump is started, the water flow switch sends an instruction to the high-voltage discharger, after the high-voltage discharger is started, the instruction is sent to the gas proportional valve, the gas proportional valve starts to ignite, and cold water in the copper pipe 2 is heated in the heat exchanger.
When the copper pipe 2 is processed, at least one time of liquid or paste anti-corrosion solder (for example, powder spraying) such as phosphorus-copper-tin-nickel solder is attached to the inner wall of the copper pipe 2, then air is blown into the copper pipe 2 to blow out large-particle phosphorus-copper-tin-nickel solder, and a thin phosphorus-copper-tin-nickel solder layer is remained; and L, enabling the temperature of the heat exchanger 1 to reach 800 ℃, so that the anti-corrosion solder is melted and mutually diffused with the metal on the inner wall of the copper pipe 2 to form the nickel coating 21.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
