detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Figure 1-2, a dual-function gas steam water heater includes a heat exchanger 2, a circulation pipe 6, a gear 8, a box body 12, a water inlet 14 and a temperature display screen 17, and a temperature display screen is installed on the surface of the box body 12 17. A switch 16 is installed above the temperature display screen 17, and a temperature control key 13 is installed on the left side of the switch 16, a gas inlet 15 is installed under the box body 12, and a water inlet 14 is installed on the right side of the gas inlet 15, and the water inlet 14 is on the right side. A warm water outlet 18 is installed on the side, and a heat exchanger 2 is installed inside the box body 12, which can effectively exchange the hot air and cold air in the water heater to achieve the purpose of energy saving. The circulation pipe 6 is installed on the right side, the burner 4 is installed under the heat exchanger 2, and the water vapor linkage valve 5 is installed under the burner 4. The dual-function valve can ensure the stability of the valve and the safety of the equipment. The circulation pipe 6 A two-way valve 7 is installed below, and a gear 8 is installed under the two-way valve 7, a three-way valve 9 is installed under the gear 8, and a gear lever 10 is installed under the three-way valve 9, and a joint is installed on the right side of the water-steam linkage valve 5. The flow pipe 3 and the two-way valve 7 are connected to the three-way valve 4 through the gear lever 10. The two valves are fixed and driven by the gear lever 10 to form a structure in which one valve rotates and the other valve moves accordingly. A smoke hood 11 is installed on the surface, and a steam outlet 19 is installed on the right side of the warm water outlet 18 .

Working principle: When using the dual-function gas steam water heater, turn on the switch 16.
