Description

A kind of solar energy water heater pipe emptier

The utility model relates to solar water heater, specifically belongs to a kind of improvement to the local member of solar water heater.

Natural heat energy bathing provides convenience to solar water heater for people make full use of.Present solar water heater normally by water tank, water supply line, running water stop valve, the bathing fire hose is first-class constitutes, it is simple in structure, and is easy to use.But also there are some unsatisfactory parts in it.For example, the solar water heater of this structure, after filling with water to water tank, remaining in water tank below to the water between stop valve can't discharge.Therefore, when using in the winter time, usually can cause the feed pipe pipeline of outdoor section to freeze because of there's a sudden fall in temperature, serious also can cause the feed pipe bursting by freezing.For addressing this problem, CN1313491 discloses a kind of exempt to freeze solar water heater water supply system and special electromagnetic valve.It is to be made of attemperater, thermal-collecting tube, upper and lower conduit road and spilling water pipeline, and the key point of its design is to be connected to a special electromagnetic valve that links to each other with the upper and lower conduit road on water tank.Though this design has solved the antifreeze problem of existing solar water heater water supply system, its cost is higher relatively, and easy-maintaining not.

The purpose of this utility model just provide a kind of simple in structure, cost is low, for ease of maintenaince, solar energy water heater pipe emptier easy to use, to guarantee that solar water heater can normally use in the winter time.

The purpose of this utility model is achieved in that designed solar energy water heater pipe emptier, includes feed pipe, is connected with water tank and bathing valve on the feed pipe, and its design main points are that the junction of feed pipe and water tank is provided with exhaust-valve; Between feed pipe, be provided with the exhaust-valve linked switch.

The solar energy water heater pipe emptier of design like this, interface at water tank and feed pipe is installed exhaust-valve, the exhaust-valve linked switch is installed in the feed pipe above indoor running water stop valve, can open at indoor control exhaust-valve by this switch, finish the emptying of water in the feed pipe pipeline, thereby solved the problem that winter solar energy water heater pipeline freezes.

Be described in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of exhaust-valve among Fig. 1.

Fig. 3 is the structural representation of exhaust-valve linked switch among Fig. 1.

As shown in Figure 1, the utility model includes feed pipe 3, and bathing valve 7, running water stop valve 4 are installed on the pipeline of feed pipe 3.Above feed pipe 3, be connected to water tank 9, exhaust overflow pipe 10 is arranged on the water tank 9.Water tank 9 places on the outdoor roof 8, and exhaust-valve 1 is installed in the junction of feed pipe 3 and water tank 9, and exhaust-valve linked switch 5 is installed on the pipeline of the feed pipe 3 between bathing valve 7 and the running water stop valve 4, also can connect a shower nozzle 6 at bathing valve 7 places.Exhaust-valve 1 is as shown in Figure 2 structure preferably.Its housing is made threeway shape, its upper port and side port place are provided with gas barrier plate 13 in outer waterstop 11 of spring and the spring respectively, the bottom of gas barrier plate 13 is connected with interlock rope 2 respectively in waterstop 11 and the spring outside spring, and interlock rope 2 passes in the lower port of exhaust-valve 1 and the feed pipe 3 and is connected with exhaust-valve linked switch 5.Interlock rope 2 can adopt the steel wire rope material to make.The upper and lower end of exhaust-valve 1 can be with spiral shell button 15,16, is used for being connected with the interface of water tank 9 and the interface of feed pipe 3.The outer waterstop 11 of the spring of exhaust-valve 1 is positioned at the outer end of the upper port of emptying valve body, and the outer waterstop 11 of spring fixes by spring 12 and emptying valve body; Gas barrier plate 13 is positioned at the inner of exhaust-valve side port in the spring, and spring is fixed by spring 14 and emptying valve body at interior gas barrier plate 13.Exhaust-valve linked switch 5 is as shown in Figure 3 structure preferably, it is made of valve body 19, control wheel 17, the two ends of its valve body 19 are connected with feed pipe 3, be fixed with rotating middle shaft 18 on the valve body 19, the lower end of the interlock rope 2 of this 18 inboard and exhaust-valve is connected to a fixed, and is connected with control wheel 17 in this outer end of 18.This form exhaust-valve and gauge tap thereof, structure is more simple, and is also very convenient during use.

When practical application, when needs carry out the surplus water emptying of feed pipe, at first rotation control takes turns 17, interlock rope 2 is tightened up because of being fixed on to twine on the rotating middle shaft 18, gas barrier plate 13 is at the pulling lower compression spring 12 and the spring 14 of interlock rope 2 in outer waterstop 11 of spring this moment and the spring, and the outer waterstop 11 of spring blocks the upper port of exhaust-valve, guarantees that the water in the water tank 9 no longer flows out, after gas barrier plate 13 compressed springs 14 in the spring simultaneously, the side port of exhaust-valve was opened.At this moment, open bathing valve 7 again, the surplus water of exhaust-valve 1 to the supply channel of 7 on bathing valve just under the gravity effect, is discharged from shower nozzle 6, thereby has been reached the emptying purpose.When needs hot water or in water tank 9 during water filling, only need reverse rotation control wheel 17, make interlock rope 2 be in the nature relaxed state, this moment is under the elastic force effect of spring 12, the outer waterstop 11 of spring is jack-up upwards, and the upper port of exhaust-valve 1 is opened and connects with water tank 9, simultaneously, gas barrier plate 13 blocks exhaust-valve 1 side port under the effect of spring 14 in the spring, thereby prevents that the water in the feed pipe from flowing out from here.After opening running water stop valve 4, running water just injects water tank 9 through feed pipe 3; Close running water stop valve 4, open bathing valve 7, the hot water in the water tank 9 just flows out from shower nozzle 6.

The utility model design is ingenious, simple in structure, so easy-maintaining and cost are low.Very suitable the northern area of China is used winter.
