Abstract
The invention discloses a water feeding control device of a solar energy water heater, which is provided with a floater-valve core locking mechanism and is characterized in that the floater-valve core locking mechanism is arranged on the external side of a water tank and in a floater chamber communicated with the water tank. The water feeding control device can enable the water temperature inside the floater chamber to be more than or less than the water temperature of the water tank; thereby, the scaling of the valve core is reduced; the sealing performance of the valve core is reinforced; the locking effect of the valve core is improved; the waste of the water resources is reduced; meanwhile, the water feeding control device provides great convenience for the maintenance of the floater-valve core locking mechanism. When a bidirectional valve is further adopted by the water feeding control device, the water tank of the water heater can supplement water at any time after the water outlet pipe is closed and automatically stop the water feeding after the water level reaches the requirement so that the flood situation possibly caused by the carelessness of the user who forgets to close the valve is avoided; the water resource is further saved.
Description
Technical field the present invention relates to solar water heater, directly relates to the control device of solar water heater.
Background technology is present, water is also very general on the hand-guided solar water heater, because the whole water process need of going up waits for a period of time, people often just forget after opening valve and remove to turn off valve again, thereby usually cause from the problem of a large amount of overflows of steam vent of roof water tank.The one, wasted precious water resource; The 2nd, also can make before the room ground behind the house form ponding sometimes, make troubles for people's trip.People improved the water-supply apparatus of solar water heater afterwards, just had in the actual life to install float-spool lockable mechanism additional in solar water container.During last water, the spool of mechanism is opened because of the power of water; When water level reached the demand height, the float levitating was closed by the spool that lever links by force with float, thereby had realized under the unattended state closing that water-feeding system is implemented.Yet float-spool lockable mechanism is set in water tank inside drawback is also arranged, that is exactly that spool soaks in hot water for a long time, very easily fouling, thus the locking effect is descended, also can make water tank slowly go up water and form overflow, and also extremely inconvenient to the maintenance of float-spool lockable mechanism.
Summary of the invention purpose of the present invention will provide a kind of improved water-supply control device of solar water heater exactly, thereby it can overcome the interior employing of the existing water tank easy fouling that float-the spool lockable mechanism exists effectively, makes the locking deleterious make water tank slowly go up water formation overflow and safeguard inconvenient drawback.
The object of the present invention is achieved like this: water-supply control device of solar water heater, have float-spool lockable mechanism, described float-spool lockable mechanism be arranged on the water tank outside and with the float chamber of water tank UNICOM in.
As further scheme of the present invention be: two-way valve also is set between upper hose and outlet pipe.
The present invention is owing to adopted the split setting with water tank and float chamber, thereby the water temperature that makes float chamber is significantly less than the water temperature of water tank, thereby alleviated the fouling of spool, strengthened the sealing property of spool, improved the locking effect of spool, reduced the waste of water resource, great convenience is provided also for simultaneously the maintenance of float-spool lockable mechanism.When the present invention further adopts two-way valve, water-heater water tank can be after outlet pipe be closed amount of makeup water at any time, and water on stopping automatically after water level reaches requirement has been avoided forgetting the flood that may cause when turning off valve because of people's negligence, has further saved water resource.
Appended drawings is a structure principle chart of the present invention, and the invention will be further described below in conjunction with accompanying drawing.
Specific embodiment accompanying drawing shows the structure of water-supply control device of solar water heater of the present invention, running water at first backs down spool 2 through upper hose 1 and enters float chamber 3, passage from float chamber 3 one sides flows into water tank 5 then, when the height of water level of water tank 5 reaches requirement, float 4 levitatings, move down locking by lever drives spool 2, enter hydraulic impact in the water tank 5 when big, may have a spot of water and overflow from steam vent 6; As required, can emit hot water the water tank 5 from outlet pipe 7, thus finish once go up water, process discharges water.When not inserting two-way valve 8 states and discharge water, along with the reduction spool 2 of water tank 5 water levels can be opened the water yield in the subsidiary water tank 5 automatically; Do not want to close the valve 9 on the upper hose 1 if water funk temperature drop is low to water tank 5 amount of makeup water at any time.When between upper hose 1 and outlet pipe 7, inserting two-way valve 8, connect water on the upper hose 1, after water level arrived the demand height, float 4 levitatings drove spool 2 lockings; When using hot water, two-way valve 8 is connected outlet pipes 7, and upper hose 1 is closed automatically, use up hot water after, two-way valve 8 turns to upper hose 1 direction to continue to go up water again, outlet pipe 7 is closed automatically simultaneously.For adjusting the water temperature of sprinkler head 10, can go out to insert a running water pipe on the sprinkler head 10 again.
