The solarenergy water heater self-colsing liebert
Technical field
The utility model relates to the solarenergy water heater self-colsing liebert.
Background technique
Solar water heater has good energy-saving effect because of it and using method is easy is used widely.People normally are installed in solar water heater not only to be convenient to sunshine but also to be beneficial to produce the higher of streaming potential and put, as the roof etc.Be connected with indoor by pipeline, all finish indoor to solar water heater water supply and hot water use.Therefore, how water in time closes the problem that the water supply valve person of being to use comparatively is concerned about after finishing on to solar water heater.Mostly on the specific water level of header tank, the spilling water delivery outlet is housed on the solar water heater commonly used, be connected with indoor with pipeline, custom is called the water return pipe, its effect is when water on the solar water heater arrives predetermined water level, the water that exceeds predetermined water level will flow back to indoor from overflow by return pipe, in time close water supply valve with the prompting people.This awake showing device advantage is that structure is simple and direct, and cost is low, wakes up and shows that information is reliable, and shortcoming is to want Attended mode, could in time close water supply valve, thereby make troubles to the user.Also once there was solar water heater producer to add the level controling floating ball valve and solved water automatic control problem, but had the defective of rate of fault height and maintenance difficult at header tank.The solar water heater that also has adopts water level or the wet information sensing device of water to cooperate solenoid valve to go up water management, but also has the cost height, needs the problem of power supply and inconvenient maintenance.
The model utility content
The purpose of this utility model solves on the solar water heater in the water process exactly, can not automatic control or the problem of automatic control cost height and inconvenient maintenance.
The technical solution adopted in the utility model is: the solarenergy water heater self-colsing liebert, it comprises the ball float that is positioned at the housing inner chamber and the piston of housing, housing one side is provided with outlet pipe and the water tank turnover water pipe that is connected up and down with solar water heater water tank, the opposite side of housing is provided with intake-outlet, piston is between water tank turnover water pipe and intake-outlet, and piston is connected by connecting rod with ball float.
Adopt technique scheme, when water, the hydraulic pressure of intake-outlet reduces, and piston is moved down, water in the water tank flows in the housing from the water tank turnover water pipe, is flowed out by intake-outlet again, after water level reduces, the ball float loss of buoyance, piston descends because of gravity, keeps the water route unobstructed; During last water, when water was full, ball float buoyancy drew high piston until closing, and last water stops, thus the realization full water self-closing.
The utility model beneficial effect is: because the utility model can completely be realized self-closingly in the back at solar water heater water, the keeping an eye on of personnel when saving water avoided the waste of water resources, and simple structure, and installation and maintenance make things convenient for.
