Description

The solar energy water heater pipe emptier

Technical field

The utility model relates to a kind of solar energy water heater pipe emptier, relates in particular to a kind of solar energy water heater pipe emptier that adopts siphon principle.

Background technology

Prior solar water heater, when using in the winter time, because the water storage tank tower is in outdoor, because the part upper and lower conduit is exposed outside, if the water after using the back or going up water in the not emptying water pipe, upper and lower conduit will freeze, cause and can not normally use, therefore, those skilled in the art continually develop out various emptier, for example: Chinese patent 002421526 discloses a kind of solar water heater water pipe emptier, it adopts water inlet pipe water-filling in the bucket of calming the anger, and the water in the bucket internal gas pressure compressing water pipe enters in the storage tank, and reaches the effect that upper and lower conduit is drained, its emptying time is long, unstable properties is made complexity, and is subjected to each link influence, can not be emptied completely, can not effectively prevent the generation of freezing accident.Chinese patent 00205052.8 discloses the solar water heater of dress electromagnetism exhaust-valve in a kind of band half, movable valve plug and quiet spool are housed in its valve body, there is ball bearing on the movable valve plug right side, the driving iron core is arranged at the bottom, the iron core upper and lower side is equipped with coil respectively, the valve body upper left quarter has paddle hole, water inlet pipe and water outlet pipe is arranged at the bottom, plug-in mounting one evacuated tube in the valve body, the control circuit of water tank bottom sends the pulse enable signal coil electricity, control thus and move or move down action on the iron core and realize water inlet and water outlet and emptying, this emptier complex structure, need set up magnetic valve, the cost height.

The content of utility model

The purpose of this utility model is to provide a kind of solar energy water heater pipe emptier, and this device can overcome the shortcoming of above-mentioned existing emptier, and it is simple in structure, easy operating, easy to use and cost is low.

For achieving the above object, the technical solution adopted in the utility model is: a kind of solar energy water heater pipe emptier, it comprises a upper and lower conduit, one water supply valve, it is characterized in that: described upper and lower conduit is the n word shape, and the top of upper and lower conduit is higher than the water tank maximum water level, connect one down to indoor evacuated tube on the top of n shape upper and lower conduit, one end of described n shape upper and lower conduit is connected with water tank and extends water tank bottom, described water supply valve is located on the n shape upper and lower conduit opposite side pipeline, the end of described evacuated tube is provided with exhaust-valve, is provided with the shower water pipe above the water supply valve of upper and lower conduit, and the shower water pipe is provided with showering.

Described n shape upper and lower conduit can be for stretching into the water tank inner bottom part from tank top.

Described n shape upper and lower conduit also can be for stretching in the water tank inner bottom part outside water tank is distolateral, in the heat-insulation layer.

When n shape upper and lower conduit can be when stretching into the water tank inner bottom part from tank top, described n shape upper and lower conduit extends the water tank bottom end and is preferably the angle shape, is beneficial to into water and avoids stopping up.

The utility model utilizes the continuous exhaust-valve of evacuated tube and the open and close of water supply valve, water level with in the control n shape upper and lower conduit reaches the unlatching and the inefficacy of control siphon action, closes water supply valve, open exhaust-valve and showering, can realize the water emptying in the pipeline.It is simple in structure, easily makes, easy to operate, advantage such as cost is low, intestine evacuation velocity is fast and thorough.

Fig. 3 is the structural representation of solar energy water heater pipe emptier embodiment 3 of the present utility model.

Specific embodiments

Below in conjunction with drawings and Examples the utility model is described in further detail.

Embodiment 1, as shown in Figure 1, this solar energy water heater pipe emptier, it comprises a upper and lower conduit 1, one water supply valve 2, described upper and lower conduit 1 is the n word shape, and the top of upper and lower conduit 1 is higher than the highest spacing waterline of water tank, connect one down to indoor evacuated tube 3 on the top of n shape upper and lower conduit 1 by a threeway 5, described n shape upper and lower conduit 1 one ends 11 are for stretching in the water tank inner bottom part outside water tank is distolateral, in the heat-insulation layer; Described water supply valve 2 is located on the n shape upper and lower conduit 1 opposite side pipeline 12, and the end of described evacuated tube 3 is provided with exhaust-valve 4, is provided with shower water pipe 6 above the water supply valve 2 of upper and lower conduit, and shower water pipe 6 is provided with showering 7.Be provided with temperature adjustment water pipe 8 below the water supply valve 2 of upper and lower conduit, temperature adjustment water pipe 8 is provided with heat control valve 9.

During last water, close exhaust-valve 4, showering 7 and heat control valve 9, water on the open valve 2, to the water tank overflow pipe overflow, water tank has been full of water.During the pipeline emptying, behind the last water full water or after using, close water supply valve 2, open showering 7 and exhaust-valve 4, be stored in the water nature emptying in the upper and lower conduit 1; During water, close showering 7 and heat control valve 9 earlier, open water supply valve 2 and exhaust-valve 4, treat the top of the n of rising to shape upper and lower conduit waterborne or when exhaust-valve 4 flows out, close exhaust-valve 4 and water supply valve 2, open showering 7 again, utilize siphon principle, when being full of water in the upper and lower conduit 1, the water of water tank will be discharged; After the use, can press said process operations platoon vacant duct again, open valve 4, valve 7 ducted water are discharged from water consumption device at once.

By foregoing description as can be known, this emptier is simple in structure, easy to operate, is suitable for practicality.

Embodiment 2, and referring to Fig. 2, be with a last embodiment difference: described n shape upper and lower conduit 1 is for to stretch into the water tank inner bottom part from tank top; And it is the angle shape that described n shape upper and lower conduit extends the water tank bottom end.Water pipe is directly entered in the water tank, and stretch in the water tank perpendicular to the water tank bottom surface, needn't be as when stretching into water tank, the water tank outside need being located in the heat-insulation layer, and its end is the angle shape, is easy to Inlet and outlet water on the one hand, avoids the foreign material block ports on the other hand.

Embodiment 3, referring to Fig. 3, showed a kind of solar energy water heater pipe emptier among the figure, its difference from Example 2 is: described n shape upper and lower conduit 1 is for to stretch into the water tank inner bottom part from the top of water tank side end face, and extending the water tank bottom end equally is the angle shape.

Embodiment
