Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in detail.
As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of cold water automatic recovery system, including hot water line 10, recovery pipe 20 and cold Water lines 30, hot water line 10 is connected with water heater 40, valve 14, temperature switching valve 11 and check-valves 12 in turn;Road is changed in temperature control The water inlet end of valve 11 is additionally provided with hot water outlet pipe 13;Recovery pipe 20 is arranged between temperature switching valve 11 and check-valves 12 On hot water line 10, the end of recovery pipe 20 is provided with storage tank 21, and storage tank 21 is sealed construction;On cold water pipeline 30 Three way type venturi water-blaster 31 and link gear 33 are set side by side with, the water side of three way type venturi water-blaster 31 is provided with Cold water outlet pipe 32, the side pipe 310 of three way type venturi water-blaster 31 is connected with the water side of check-valves 12;Link gear 33 is wrapped Control valve 331, piston 335 and gangbar 334 are included, control valve 331 is arranged on cold water pipeline 30, controls the water outlet of valve 331 Pipeline is connected on cold water outlet pipe 32, and the swing arm 333 for controlling valve 331 is connected to one end of gangbar 334, and piston 335 is arranged In the recovery pipe 20 of the water inlet end of check-valves 12, the movable part 332 of piston 335 is connected to the other end of gangbar 334, together When, also linked together by fixed seat 330 between piston 335 and control valve 331.As shown in figure 4, the top of storage tank 21 sets It is equipped with pressure safety valve 22.
A kind of operation principle of cold water automatic recovery system of the present invention is, when fetching water from hot water outlet pipe 13, valve 14 The opening and closing of whole hot water line 10 is controlled, after valve 14 is opened, current first flow into temperature switching valve 11 by hot water line 10, But due to having cold water in hot water line 10, because temperature switching valve 11 has the characteristics of being opened and closed according to water temperature control piper, temperature Kong Huan roads valve 11 can open hot water line 10, and cold water will pass through the injection storage tank 21 of recovery pipe 20 and store;Due to cold water The presence of the hydraulic pressure of pipeline 30, the cold water in hot water line 10 can't be flowed into wherein;When cold water is drained, road is changed in hot water contacts' temperature control Valve 11, temperature switching valve 11 cuts off hot water line 10 after being heated, and hot water just flows to hot water outlet pipe 13.
When fetching water from cold water outlet pipe 32, the cold water in cold water pipeline 30 passes through three way type venturi water-blaster 31 simultaneously Cold water outlet pipe 32 is flowed to link gear 33, the cold water in storage tank 21 flows out from recovery pipe 20, also flows by side pipe 310 To cold water outlet pipe 32, piston 335 is driven movable part 333 to move by the effect elongation of the power of current, and movable part 332 drives again Gangbar 334 is moved, and so as to drive swing arm 333 to rotate, then swing arm 333 is opened valve 331 is controlled, and cold water pipeline 30 is opened, The cold water in cold water and cold water pipeline 30 in storage tank 21 just together flows out from cold water outlet pipe 32, increases the flow of water; After not fetching water, current disappear, the return of piston 335, so as to drive control valve 331 to close.
In the present invention, check-valves 12 is provided with hot water line 10, the cold water in cold water pipeline 30 does not flow into hot-water line Road 10;Three way type venturi water-blaster 31 makes the water in storage tank 21 from 310 suctions according to venturi principle;Link gear 33 It is opened and closed by current, increases out water speed, acts synergistically with three way type venturi water-blaster 31, effectively utilizes the system Water in storage tank 21, so as to improve efficiency;Storage tank 21 is sealed construction so as to while being not required to high-order installation, moreover it is possible to Pressure effectively in storage water supply line, the cold water for further increasing the system goes out water speed.Also, the top of storage tank 21 Pressure safety valve 22 is provided with, protection storage tank 21 is in certain safe pressure operated within range.
