Description
Technical field
The present invention relates to the solar energy hot field, especially, is a kind of water-saving type solar water heater.
Background technology
[0002] solar water heater adds hot water through the thermal-arrest plate, and detailed process is: solar radiation sees through glass cover-plate, is absorbed the back by the thermal-arrest plate and is delivered to the water in the endothermic tube along fin and tube wall.Water heat absorption back temperature in the endothermic tube raises, and proportion reduces and rises, and forms a power that makes progress, and constitutes a thermal siphon system.Along with hot water constantly on move and be stored in storage tank top, constantly replenish the lower water of temperature through circulation pipe down simultaneously, so move in circles, final whole box water all is increased to certain temperature.
Under sun-drenched weather, the water in the solar water heater water tank will seethe with excitement through about 3 hours, a large amount of steam of the water generates of boiling; Rising along with pressure; The relief valve on the attemperater top of water-saving type solar water heater can be opened, and discharges a large amount of steam and reduces pressure, under continuous light; Water in the attemperater will constantly be evaporated; The water that is evaporated under one day being exposed to the sun by day accounts for more than 1/4th of tank water, and a large amount of water are wasted, and the high temperature that continues simultaneously is exposed to the sun and has also shortened the service life of vacuum tube.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of water-saving type solar water heater, the shortcoming that this water heater can avoid a large amount of water to be evaporated simultaneously, reduces being exposed to the sun the time of vacuum tube, prolongs the service life of vacuum tube.
The technical solution adopted for the present invention to solve the technical problems is: this water-saving type solar water heater comprises attemperater and vacuum tube; Said vacuum tube is arranged in parallel and oblique cutting is gone into the bottom of attemperater; The other end of said vacuum tube embeds in the crossbeam; Said vacuum tube, attemperater and crossbeam all are arranged on the support, and the upper and lower of said attemperater one end is respectively arranged with water inlet pipe and outlet pipe, and the top of said attemperater is provided with relief tube;
The top of the junction of said vacuum tube and attemperater is provided with roller shutter; Said roller shutter is perpendicular to vacuum tube and be fixed on the attemperater; The cord two ends of said roller shutter are connected with two backguys; Two hoist engines of the connection of said backguy, said hoist engine is arranged on the two ends of said crossbeam, and said hoist engine and is arranged on attemperater pressure inside switch and is electrically connected.
As preferably; The housing of said pressure switch is cylindrical; Said housing one end is fixed in the top of attemperater inwall, and the other end is sealed by a rubber membrane, and the middle part of said rubber membrane is provided with hard contact; The axial line of said housing is provided with an end and is fixed in the metal contactting rod on the attemperater inwall, the synthetic core component that opens and closes function of said metal contactting rod and contact sets.
As preferably, said metal contactting rod is a threaded bar, and said metal contactting rod penetrates attemperater, and externally is provided with turning handle.
As preferably, said cord launches incomplete covering evacuated pipe fully, and the vacuum tube part branch exposes the maintenance water temperature stability.
The invention has the advantages that: after the water in the attemperater was heated to boiling by vacuum tube, pressure raise gradually, after reaching certain pressure; The rising of pressure makes pressure switch form path, and said hoist engine starts leaves behind the cord of roller shutter, and said vacuum tube is covered; Water in the attemperater is stopped heating; Water no longer is evaporated, and when water temperature descended, the reduction of pressure was broken off pressure switch; Cord loses hoist engine traction cord is regained, the said vacuum tube water in the heat tracing water tank that works on.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1, shown in Figure 2 be the planform sketch map of an embodiment of this water-saving type solar water heater; Fig. 3 is the amplification assumption diagram of this water-saving type solar water heater pressure switch; For the ease of saying something, Fig. 1, Fig. 2, Fig. 3 are set forth the present invention as same embodiment at present.
In the present embodiment; This water-saving type solar water heater comprises attemperater 1 and vacuum tube 2; Said vacuum tube 2 is arranged in parallel and oblique cutting is gone into the bottom of attemperater 1, and the other end of said vacuum tube 2 embeds in the crossbeam 3, and said vacuum tube 2, attemperater 1 and crossbeam 3 all are arranged on the support 15; The upper and lower of said attemperater 1 one ends is respectively arranged with water inlet pipe 12 and outlet pipe 13, and the top of said attemperater 1 is provided with relief tube 11;
Said vacuum tube 2 is provided with roller shutter 4 with the top of the junction of attemperater 1; Said roller shutter 4 is perpendicular to vacuum tube 2 and be fixed on the attemperater 1; Cord 41 two ends of said roller shutter 4 are connected with two backguys 42; Two hoist engines of the connection of said backguy 42, said hoist engine is arranged on the two ends of said crossbeam 3, and said hoist engine and is arranged on attemperater 1 pressure inside switch 5 and is electrically connected.
