Abstract
The utility model provides a water supplying and draining system of a solar water heater with an auxiliary water tank, which is mainly composed of an emptying valve, a water inlet pipe for a cold water tank, a water outlet pipe for a hot water tank, a water supplying pipeline, a water draining pipeline, an emptying one-way valve, etc., wherein the emptying one-valve is installed in a water supplying and draining common pipeline, and the upper ends of the water supplying pipeline and the water draining pipeline are respectively communicated with the water inlet pipe for the cold water tank and the water outlet pipe for the hot water tank; the insides of the water inlet pipe for the cold water tank and the water outlet pipe for the hot water tank are respectively provided with at least one one-way valve of which the direction corresponds to the direction of the water supplying pipeline and the water draining pipeline, and the directions of the one-way actions of the one-way valves which are installed in the two pipelines are opposite. The emptying valve can be an electric control valve, a pneumatic control valve, or a liquid control valve. At the time of the water supply of a water heater, running water enters the cold water tank through the emptying valve and the one-way valve inside the water inlet pipe, the one-way valve inside the water outlet pipe is closed due to the one-way action thereof, and the water temperature of water in the hot water tank can not be affected; at the time of water drainage, hot water flows out through the one-way valve in the water outlet pipe and the emptying valve; at this time, the one-way valve in the water inlet pipe is closed due to the one-way action thereby, and the water outflow temperature of the water heater can not be affected; the water supplying pipeline and the water draining pipeline can be emptied by the emptying valve.
Description
Affiliated technical field
The utility model relates to the last water and the drainage pipeline system of solar water heater, is a kind of last water and drainage pipeline system with the auxiliary water tank solar water heater specifically.
Background technology
The water tank of band auxiliary water tank solar water heater has two, one is auxiliary water tank---be cold water storage cistern, another is a boiler, the position of auxiliary water tank is higher than boiler, the boiler bottom connects heating, vacuum pipe group, vacuum tube group lower end connects water-locator, and water-locator is communicated with auxiliary water tank by connecting pipeline.The water heater of this structure can be at any time to water on the water heater, and can the water temperature in the boiler not exerted an influence.Water and sewerage are finished by a water pipe respectively on the band auxiliary water tank water heater commonly used at present.
Summary of the invention
The utility model provides a kind of last water and sewerage of novel band auxiliary water tank solar water heater, and the Shang Shui of this system and Xia Shui have a common pall to finish, and the pipeline configuration is few, and can carry out emptying to pipeline as required.
The technical scheme that its technical problem that solves the utility model adopts is: the last water of novel band auxiliary water tank solar water heater and sewerage are mainly by exhaust-valve, the auxiliary water tank water inlet pipe, the boiler outlet pipe, last water and drainage pipeline, parts such as emptying one-way valve are formed, exhaust-valve is installed in series in water heater Shang Shui and following water common pall, the upper end of last water and drainage pipeline is communicated with respectively with auxiliary water tank water inlet pipe and boiler outlet pipe, in auxiliary water tank water inlet pipe and boiler outlet pipe, at least one check valve respectively is housed, with respect to last water and drainage pipeline direction, the single effect direction of the check valve of installing in auxiliary water tank water inlet pipe and boiler outlet pipe is opposite.Exhaust-valve can be electrically-controlled valve, also Pneumatic valve, pilot operated valve device also.During water, running water enters into auxiliary water tank by the check valve in exhaust-valve and the inlet pipeline on the water heater, and the check valve in the boiler outlet pipeline is closed because of its single effect, guarantees that the water temperature in the boiler is unaffected; During following water, hot water flows out by check valve in the outlet pipeline and exhaust-valve, and at this moment, the check valve in the auxiliary water tank inlet pipeline is closed because of its single effect, thereby the leaving water temperature that guarantees water heater is unaffected; Last water and drainage pipeline also can be by exhaust-valve and emptying one-way valve emptyings.
The beneficial effects of the utility model are, the following water of water heater and the last water of auxiliary water tank are finished by a common pall, and the pipeline of water heater is deployed simple, also can go up the evacuation and anti-freezing of water and drainage pipeline as required.
