Abstract
The utility model relates to a water supply and drainage pipe lines for solar energy water heaters, in particular to a water supply and drainage pipe line evacuation device for solar energy water heaters. The utility model aims to evacuate the stored water in the water supply and drainage pipe lines of a water heater, and reaches the purpose that hot water is provided when the drainage pipe line is opened. The utility model is composed of an exhaust valve, water supply and drainage pipe lines of a water heater, an air supercharger and a control line. The exhaust valve is connected in series in the water supply and drainage pipe lines of the water heater, and the air supercharger is arranged indoors. The utility model is characterized in that the exhaust valve is a pneumatic control valve whose opening and closing are controlled by gas pressure, and is connected with the pneumatic control valve through an air pipe. The pneumatic control valve can be an on-off valve or a change valve. The water in the drainage pipe line of the water heater is evacuated and discharged through the gas supercharger and the pneumatic control valve, and is controlled without power. The hot water is provided when the drainage pipe line is put off. The utility model is safe and saves water.
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 emptier of solar water heater specifically.
Background technology
Water and drainage pipeline system on the solar water heater commonly used at present are because the discharging valve in the drainage pipeline has a large amount of waters indoor in the drainage pipeline between discharging valve and the water heater always.When the drainage pipeline that needs water heater provides hot water, at first get rid of the water in the pipeline, cause the waste at water source, and the pipeline of water also easily produces the frozen pipe phenomenon in the winter time all the time.
Summary of the invention
The utility model provides a kind of last water and drainage pipeline emptier of solar water heater, and this device can make the last water and the drainage pipeline emptying of water heater, and the drainage pipeline of water heater is once having opened hot water.
The technical scheme that its technical problem that solves the utility model adopts is: the last water of novel solar water heater and drainage pipeline emptier are made up of last water and drainage pipeline, gas booster, the control piper of exhaust-valve, water heater, exhaust-valve is installed in series on water heater in the water and drainage pipeline, gas booster is installed in indoor, it is characterized in that: exhaust-valve is the pneumatic control valve that air pressure control is opened or closed, and connects by tracheae between the pneumatic control valve.But pneumatic control valve switch valve, also reversal valve.
The beneficial effects of the utility model are, the drainage pipeline of water heater by gas booster and pneumatic control valve emptying, discharge water, no electric control is once having put hot water, safety, water saving.
