[0002] The current domestic hot water supply system adopts a single-pipe non-pressurized type, but the solar water heater of this type has insufficient water supply pressure on the top floor, and the time for releasing hot water at the bottom floor is too long, and the water supply pressure is unstable, resulting in too little hot water. It is inconvenient to use. Nowadays, a large number of residential solar systems use electric auxiliary heating. The hot water in the solar water heater is about to run out. Electric auxiliary heating can be used to continue to use hot water. However, electric energy is more expensive than domestic gas, which is not conducive to saving energy

Embodiment Construction
[0012] Such as figure 1 A combined water supply system of a solar water heater and a domestic gas water heater is shown, including a solar water heater 1 and a gas water heater 2. The hot water outlet of the water supply system is divided into two paths, and one path passes through a hot water pipe 5 equipped with a shut-off valve 4 and a solar water heater. The water outlet of the water heater 1 is connected, and the other way is connected with the water inlet of the gas water heater 2 through the hot water pipe 5 installed with the solenoid valve 7, the hot water pipeline pump 3 and the shut-off valve 4 in sequence; Valve 4, electromagnetic valve 7, check valve 8 and water supply pipe 6 of stop valve 4 are then divided into two routes, one of which is connected to the water inlet of solar water heater 1 through hot water pipe 5 installed with stop valve 4, and the other is installed in sequence through A hot water pipe 5 with a check valve 8 and a shut-off valve 4 is connect...

The invention relates to a joint water supply system integrating a solar water heater and a domestic gas water heater. The joint water supply system comprises a solar water heater and a gas water heater, wherein a hot-water outlet of a water supply system is divided into two paths, one path is connected with a water outlet of the solar water heater through a hot water pipe with a stop valve, and the other path is connected with a water inlet of the gas water heater through a hot water pipe sequentially equipped with an electromagnetic valve, a hot-water pipeline pump and a stop valve; a water inlet of the water supply system is dived into two paths after passing through a feed pipe sequentially equipped with a stop valve, an electromagnetic valve, a check valve and another stop valve, one path is connected with a water inlet of the solar water heater through a hot water pipe with a stop valve, and the other path is connected with a water inlet of the gas water heater through a hot water pipe sequentially equipped with a check valve and a stop valve. By adopting a top-water pressure-bearing double-pipe water supply system, cold and hot water pressures are from the same source, so that the water supply pressure can be kept stable; by adopting gas, instead of electricity, as an auxiliary heating energy, hot water can be conveniently and continuously used and the energy can also be saved.
Description
technical field [0001] The invention relates to a civil hot water supply system, in particular to a combined water supply system of a solar water heater and a domestic gas water heater. Background technique [0002] The current domestic hot water supply system adopts a single-pipe non-pressurized type, but the solar water heater of this type has insufficient water supply pressure on the top floor, and the time for releasing hot water at the bottom floor is too long, and the water supply pressure is unstable, resulting in too little hot water. It is inconvenient to use. Nowadays, a large number of residential solar systems use electric auxiliary heating. The hot water in the solar water heater is about to run out. Electric auxiliary heating can be used to continue to use hot water. However, electric energy is more expensive than domestic gas, which is not conducive to saving energy. Contents of the invention [0003] The technical problem to be solved by the present invent...
