Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive work, are related to the scope of the present invention.

As shown in fig. 1, the present embodiment proposes

A solar water heater pipeline structure comprises a communicating piece 20, wherein a first pipeline 21, a second pipeline 22 and a third pipeline 23 are arranged in the communicating piece 20, the second pipeline 22 is communicated with a water outlet of a solar water heater water tank 10 and the first pipeline 21, the third pipeline 23 is communicated with a water conveying pipe 30 and the first pipeline 21, a first end of the first pipeline 21 is communicated with an emptying pipe 40, a second end of the first pipeline 21 is provided with a switch device 24 for controlling the pipeline to be communicated, and a water drain valve 50 is arranged on the water conveying pipe 30.

The communication of the pipelines in the communicating piece 20 is controlled by the switch device 24, when the switch device 24 is opened, the second pipeline 22 and the third pipeline 23 are communicated through the first pipeline 21, the hot water in the water tank 10 of the solar water heater can normally flow into the water pipe 30, when the water is normally used, the water drain valve 50 is closed, and the water pipe 30 conveys the hot water to the water using equipment; when switching device 24 closed, second pipeline 22 and third pipeline 23 can't switch on through first pipeline 21, hot water can't flow in raceway 30 through connecting piece 20 this moment, open the valve 50 that drains this moment, the interior remaining water of raceway 30 is discharged from the valve 50 that drains, evacuation pipe 40 plays the effect of the inside and outside pressure of balance, guarantee can normally drain, through the water in the above-mentioned device discharge raceway 30 way, can avoid raceway 30 to freeze the problem stifled and pipeline cold water, and simple structure is practical moreover.

The second line 22 is close to the second end of the first line 21, the third line 23 is close to the first end of the first line 21, and the switching device 24 includes:

a piston 241 slidably disposed in the first conduit 21,

a flange 242 provided at the second end of the first pipe 21, closing the opening of the second end,

a connecting rod 243 connected with the piston 241 through the flange 242,

an elastic member 244 disposed between the piston 241 and the flange 242, providing an elastic force for moving the piston 241 away from the flange 242;

and a driving mechanism 245 for driving the connecting rod 243 to move.

The switch device 24 is disposed at the second end of the first pipeline 21, and drives the connecting rod 243 to move through the driving mechanism 245, so as to drive the piston 241 to slide in the first pipeline 21, and because the second pipeline 22 is close to the second end of the first pipeline 21, and the third pipeline 23 is close to the first end of the first pipeline 21, the piston 241 can move between the second pipeline 22 and the third pipeline 23, so that the second pipeline 22 and the third pipeline 23 cannot be conducted through the first pipeline 21;

the elastic force provided by the elastic member 244 may make the movement of the piston 241 more stable.

Piston 241 is shorter in length than the interface of second conduit 22 with first conduit 21.

The piston 241 cannot completely block the interface between the second pipeline 22 and the first pipeline 21, so that when the switch device 24 is opened, the piston 241 completely separates the second pipeline 22 from the first pipeline 21, and the piston 241 can normally slide.

The driving mechanism 245 is a manual control mechanism or an electric control mechanism.

The emptying pipe 40 has its mouth facing upwards and its height is higher than the liquid level in the tank 10.

The phenomenon that the emptying pipe 40 is completely filled with water when water is normally used is avoided, so that liquid flows out from the pipe orifice when the switching device 24 is closed after the water is used, freezing is caused, and the emptying is influenced.

The air release valve 60 is arranged at the nozzle of the emptying pipe 40.

The sundries are prevented from entering the emptying pipe 40 to block the emptying pipe 40, and the emptying is prevented from being influenced.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
