Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of its compact structure, reasonable in design, simple to operate at the above-mentioned state of the art, prevents that in the winter of cold the solar water heater water transport pipeline is frozen to block, the antifreezing solar energy electric ball valve of bursting by freezing.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of antifreezing solar energy electric ball valve, be located at the outlet port of water heater, it comprises valve body, valve gap, ball valve core, valve rod and electric controller, wherein be respectively equipped with the joint that communicates with the water outlet of the water intake of hot-water line and water tank on the valve body, valve gap is fixedly connected on the sidepiece of valve body, the axial position that water outlet is relative, spool is arranged on valve body and valve gap, in the cavity that joint forms, electric controller is arranged on the top of valve body, valve rod is arranged in the top tubular cavity of valve body, the two ends of valve rod connect spool and electric controller respectively, it is characterized in that described valve gap is provided with a suction port, in the interface of suction port, be provided with the plug of cooperation movably.
As improvement, described plug is
Type comprises fixedly connected clamping plate, packing ring and sealing gasket, and described packing ring is inserted in the interface of suction port movably, and described sealing gasket is embedded between clamping plate and the packing ring, matches with the interface end face of suction port.
As improvement, described water intake and water outlet are conplane 90 degree and are provided with, and described suction port is coaxial with water outlet.
Improve, the contacting point of the rear and front end of described spool and valve channel, valve gap is provided with sealing gasket again.
Further improve, between described valve body and the valve gap, between valve body and the electric controller for being threaded.
At last, between described valve gap and the interface for being threaded.
Compared with prior art, advantage of the present utility model is: offer suction port on valve body, and in the interface of suction port the movable plug that cooperation is installed, as long as switch by the control electric controller, just may command ball valve rotation, when closing, ball valve revolves and turn 90 degrees, suction port communicates with water intake, uses water valve as long as open, and pipeline inner pressure will descend, plug separates with suction port, air enters the water emptying in the pipeline, and the utility model is compact structure not only, reasonable in design, can prevent that in the winter of cold the solar water heater water transport pipeline is frozen to block, bursting by freezing; And easy to operate, can not influence the use of product because of atrocious weather in the indoor telecontrol of carrying out.
