Description

Solar water heater automatic water-supply apparatus

Technical field

The utility model relates to the corollary apparatus of solar water heater, is specifically related to solar water heater automatic water-supply apparatus.

Background technology

Solar water heater, simple in structure because of it, price is low, be again to utilize natural green energy resource, advantage such as use cost is also low is used very extensive in China.Solar water heater does not generally have level displaying device, and when feed-tank supplied water, the user was difficult to grasp the water time, and during operation or the quantity of water in water tank deficiency, or the full water overflow causes water resource waste.Existing level displaying device mostly is the sensing electronics and shows, the high and damage easily of price.The existing big sun energy water heater automatic water-supply apparatus that appears on the market is made up of water supply valve, water inlet pipe, upper hose, overflow pipe, drainpipe etc.In the last water, after water tank water was full, the water that diffuses out was back to water-supply apparatus through overflow pipe, closes water supply valve, opens drainpipe, and the water that diffuses out just flows to sewer, causes the waste of water resource equally.A kind of automatic water-supply control valve also appearred on the market, but because valve body all is to adopt rubber seal, when cooling water and backheat water were all a pipeline, the bigger temperature difference made very easily that rubber blanket is aging, distortion and fouling, and poorly sealed, just can not guarantee the device automatic water-supply.In addition, present big sun can the water heater automatic water-supply apparatus, all can not work as cut off the water can or hydraulic pressure can close automatically when hanging down.

Summary of the invention

The utility model is at the weak point of above-mentioned existence, a kind of solar water heater automatic water-supply apparatus has been proposed, purpose is to make this device automatic loading water performance more reliable and more stable, and when cutting off the water or hydraulic pressure can be closed when low automatically, more helps the conserve water resource and prolongs service life of product.

Technical solution of the present utility model:

The solar water heater water tank of the utility model and prior art (hereinafter to be referred as main water box) and hold concurrently up and down water pipe (hereinafter to be referred as water pipe), the supporting use of running water pipe of row mainly are made up of flow direction control valve and the secondary water tank that includes floating ball device.Flow direction control valve is provided with flow valve and sealing valve in pipeline, an end of flow valve links to each other with running water pipe, and an end of sealing valve is communicated with water pipe, and the other end of water pipe runs through secondary water tank, and communicates with main water box.Its section that is positioned at secondary water tank of water pipe is provided with a plurality of three-way pipes, their the 3rd end leads in the secondary tank box respectively, lead to the water inlet on main water box top, lead to the water inlet column jecket of floating ball device, and each three-way pipe place be provided with respectively different towards check valve.

The beneficial effects of the utility model

(1) the utility model automatic water stopping is effective, and last water is fast, and is anhydrous excessive, helps the conserve water resource.

(2) the utility model is when cutting off the water or hydraulic pressure is crossed and can be closed automatically when low, can not cause that the thermal-collecting tube of solar water heater that is exposed to the sun is prominent meets cold water and breakage.

(3) flow direction control valve of the present utility model, the secondary water tank that comprises floating ball device all do not contact high-temperature water and vapour, thus less scaling, prolonged service life of this device.

(4) the utility model also can be given the solar water container filling up water when hydraulic pressure is low.

Description of drawings

Accompanying drawing is a sectional structure schematic diagram of the present utility model;

The specific embodiment

As shown in the figure, the utility model mainly is made up of flow direction control valve 1 and the secondary water tank 2 that includes floating ball device 423.Flow direction control valve is provided with flow valve 11 and sealing valve 12 in pipeline, an end of flow valve links to each other with running water pipe 7, and an end of sealing valve is communicated with water pipe 4, and the other end of water pipe runs through secondary water tank 2, and communicates with main water box 5.On the water pipe, the section that is positioned at secondary water tank is provided with three-

way pipe

41,42,43.The 3rd end of three-way pipe 41 leads in the secondary tank box, and is provided with inverted check valve 411; The 3rd end of three-way pipe 42 leads to the water inlet 51 on main water box 5 tops, also is provided with check valve 421; Three-way pipe 43 the 3rd end leads to the water inlet column jecket 432 of secondary water tank 2, is provided with check valve 431 at its place, two go sides.Between threeway 42 and threeway 43, be provided with and be inverted check valve 21.In addition: buoyant device (423) is provided with the water inlet (51) that floating valve (422) is positioned at main water box (5) top and locates; The top of secondary water tank is provided with passage 6.

Below in conjunction with accompanying drawing, sketch the course of work of the present utility model:

(1) must be on main water box 5 during water, close hot-water switch 31, open cold water mediation switch 33, open the switch 111 of flow valve 11, the current that running water pipe 7 flows out withstand the flow valve 11 that is opened, through sealing valve 12 ingoing stream pipelines 4, because

check valve

411,21 is obstructed, then current have only process check valve 421 to make progress again, back down check valve 512 through buoyancy switch 422 from the water inlet 51 on main water box 5 tops and flow into main water box 5, after water is full, water body just enters the delivery port 52 of main water box bottom, again because check valve 21 is obstructed, water body is had to enter secondary water tank from the water inlet column jecket 432 of check valve 431, secondary subsequently cistern water level raises, ball float 423 come-ups, ball-cock assembly 422 is closed water inlet 51.Above process has realized water on main water box, and has closed water-supply apparatus automatically.

(2) when just during water, just meeting with suddenly and cut off the water on main water box, because device is provided with sealing valve 12, the water in the solar water heater main water box then can not reflux, and does not have current in the water pipe, and flow valve 11 is closed automatically; In case come water, can not carry out automatic loading water to solar energy yet, special in the time-division at noon of sweltering heat, can be sharp not bad solar energy heat collection pipe because of going up cold water suddenly, can prolong the service life of water heater thermal-collecting tube.

(3) in the time of hot water must being used, open hot-water switch 31, just hot water from the delivery port 52 of solar water heater main water box bottom, flows to tap 32 (as long as opening switch 31 as need mediation cold water) through check valve 21, water pipe 4, hot-water switch 31.In addition the water in the secondary water tank also through check valve 411, flow to water halter 32, secondary cistern water level descends, ball float sinks, to realize the automatic loading water of next time again.
