Abstract
The utility model relates to a pipeline emptying valve of a solar water heater, which comprises an electric speed reducer, a water tank and water pipe joint, a valve body sealing ring, a valve body channel, a valve body channel sealing gasket, a water pipe joint, an emptying pipe joint, a valve body, a valve body shell and a connecting rod. The electric speed reducer is connected with the valve body by the aid of the connecting rod; water and air pass through the valve body channel; one end of the valve body channel projects and is connected with the water pipe joint; the valve body sealing ring is arranged between the valve body and the valve body shell; the valve body channel sealing gasket is arranged between the valve body channel and the valve body shell; the water pipe joint can be connected with a water pipe and used for feeding and discharging water for the water heater; the water tank and water pipe joint is connected with a water tank of the water heater; and the emptying pipe joint is used for discharging water in the water pipe. The valve body is turned so that the valve body channel is aligned to the water tank and water pipe joint, and then the water can be fed and discharged. When the water heater is unused, the valve body channel is aligned to the emptying pipe joint, and the water in the water pipe is discharged. The pipeline emptying valve is capable of achieving the purposes of pipeline freezing prevention and water and electricity economization, and has higher popularization value.
Description
Technical field: the utility model belongs to technical field of solar water heaters, is specifically related to a kind of pipeline emptying valve for solar water heater.
Background technology:, use winter and cause cold pipe phenomenon easily if solar water heater is not installed exhaust-valve.Mainly there is inconvenient operation in existing exhaust-valve technology, the phenomenon that valve body easily gets rusty.
Summary of the invention: the purpose of this utility model is exactly the problem that exists at existing solar water heater emptying valve, provides a kind of technology simple, easy to use, the pipeline emptying valve for solar water heater of good sealing effect.
The utility model adopts following technical scheme: a kind of pipeline emptying valve for solar water heater of the utility model, form by motorized speed reducer, water tank waterpipe jointing, valve seals, valve channel, valve channel sealing gasket, waterpipe jointing, evacuated tube interface, valve body, valve shell, link rod; Said motorized speed reducer and valve body join by link rod; Said valve channel is used for by water and air, and valve channel one distal process goes out with waterpipe jointing to join, and valve body serves as that axle rotates with valve channel one end protuberance and link rod with the valve body connecting place; Be provided with valve seals between valve body and the valve shell, be provided with the valve channel sealing gasket between valve channel and the valve shell; Waterpipe jointing can connect water pipe and be used for water heater Shang Shui and Xia Shui, and the water tank waterpipe jointing connects water-heater water tank, and the evacuated tube interface is used for getting rid of the water of water pipe; When water heater need add water, motorized speed reducer drove valve body by link rod and rotates, and valve channel is aimed at the water tank waterpipe jointing, and water can arrive solar water heater water tank through valve channel and water tank waterpipe jointing by waterpipe jointing like this; When water heater time spent not, motorized speed reducer drives valve body by link rod and rotates, and valve channel is to the evacuated tube interface, and water can bleed off through valve channel by waterpipe jointing like this, the water in the eliminating water pipe.
The utility model can reach the freezing prevention tubing in winter, and the purpose that reaches water saving, economize on electricity has good popularization value.
Description of drawings: Fig. 1 is the utility model structural representation
Among the figure: the 1st, motorized speed reducer, the 2nd, water tank waterpipe jointing, the 3rd, valve seals, the 4th, valve channel, the 5th, valve channel sealing gasket, the 6th, waterpipe jointing, the 7th, evacuated tube interface, the 8th, valve body, the 9th, valve shell, the 10th, link rod.
The specific embodiment: in the drawings, motorized speed reducer 1 joins by link rod 10 with valve body 8, valve channel 4 one distal process go out with waterpipe jointing 6 to join, and are provided with valve seals 3 between valve body 8 and the valve shell 9, are provided with valve channel sealing gasket 5 between valve channel 4 and the valve shell 9; Waterpipe jointing 6 can connect water pipe, is used for water heater Shang Shui and Xia Shui, and water tank waterpipe jointing 2 connects water-heater water tank, and evacuated tube interface 7 is used for getting rid of water pipe water; When water heater need add water, motorized speed reducer 1 drove valve body 8 by link rod 10 and rotates, and valve channel 4 is aimed at water tank waterpipe jointing 2, and water can arrive solar water heater water tank through valve channel 4 and water tank waterpipe jointing 2 by waterpipe jointing 6 like this; When water heater time spent not, motorized speed reducer 1 drives valve bodies 8 by link rod 10 and rotates, 4 pairs of evacuated tube interfaces 7 of valve channel, and water can bleed off through valve channels 4 by waterpipe jointing 6 like this, the water in the eliminating water pipe.
