Description

The solarenergy water heater self-colsing liebert

Technical field

The utility model relates to the solar energy water supply valve, especially water supply valve that can be self-closing.

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 is characterized in that it comprises valve casing, closes the self-closing starting drive of water into and the flow mixing device that hot water and cold water are mixed automatically, be provided with self-closing chamber in the described valve casing, self-closing starting drive is positioned at self-closing chamber, and flow mixing device is fixed on the back in self-closing chamber; Described self-closing starting drive comprises return pipe, the pinion and rack that is made of gear and tooth bar, the expanding block of water-swellable, be fixed with sliding chute seat on the chamber wall in self-closing chamber, sliding chute seat is provided with chute, the tooth bar back is positioned at the chute of sliding chute seat, tooth bar can be slided up and down along chute, wheel and rack cooperates, and the bottom in self-closing chamber is provided with drain opening; The end of described tooth bar is provided with the holder basket, and expanding block is positioned at the holder basket, and the end of expanding block is relative with the tooth bar end, makes that the extruding tooth bar moved when expanding block expanded, and the pipe end of intake pipe is positioned at a side of expanding block, makes directly to rush at expanding block when intake pipe has water; Described flow mixing device comprises tap water passage, water channel and exhalant canal up and down, the tap water passage and up and down water channel be connected respectively at middle part and bottom by central passage and foot passage, exhalant canal is connected with foot passage, central passage is provided with cold valves, central passage is realized opening and closing, foot passage is provided with the water temperature modulating valve with the exhalant canal place of connection, regulates two edge channel water-outlet quantitys and enters exhalant canal; Gear is fixed in the cold valves rotating shaft, makes gear rotate drive cold valves rotating shaft rotation and closes central passage.

Adopt technique scheme, when normally having a bath, close cold valves, central passage is closed, tap water flows into from the tap water passage, and the hot water in the solar energy flows into from water channel up and down and converges at foot passage, and is regulated to flow out from exhalant canal by the water temperature modulating valve and carry out bathing.When last water, close the water temperature modulating valve, open cold valves, this hour rack is positioned at the bottom, when water in the solar water container is full, enter in the self-closing chamber from return pipe, and rush at expanding block, expanding block produces and expands, to move on the jack-up tooth bar, move on the tooth bar and promote the gear rotation thereupon, cold valves is rotated close, thereby reach self-closing purpose.

For increasing thrust to tooth bar, it is characterized in that it also comprises two curved tension spring A and tension spring B, two tension springs are symmetrically distributed in the both sides of tooth bar end, and an end pushes the tooth bar both sides respectively, and the other end is spacing to two springs respectively by anchor plate A and anchor plate B.When moving on the tooth bar, spring also will produce thrust upwards, further promote to move on the tooth bar like this.

Spacing for tooth bar being carried out the bottom, it is characterized in that bi-side, described tooth bar bottom are provided with boss, be fixed with the extruding boss limited post spacing on the self-closing chamber wall of boss below to tooth bar.

In sum, the utility model beneficial effect is: the overflow backwater pours expanding block behind the solar water heater filling up water, expanding block suction back volume increases, touch tooth bar, remove the tension force static balancing of spring, and then tooth bar is slided along the tooth bar chute, promote the gear rotation meshing with tooth bar at spring, close cold valves, therefore need not manually to close.Simple in structure, easy break-down is not easy to maintenance, low cost of manufacture.
