Abstract
The utility model relates to an evacuation valve of a solar water heater, in particular to a built-in solar electromagnetic evacuation valve, which comprises a valve body, an overflow pipe, an evacuation pipe, and an electromagnet, a micro switch, an electromagnetic valve top rod, a silica gel sealing body, a spring and the like which are arranged in the valve body. The built-in solar electromagnetic evacuation valve is characterized in that an insulating layer of a water tank is internally provided with the electromagnetic evacuation valve; a ball valve of the electromagnetic evacuation valve is fixedly provided with a top rod which faces down and passes through the valve body; two sealing cavities are sheathed on the top rod between the valve body and the ball valve; and the upper one of the two sealing cavities is a silica gel sealing cavity formed by a silica gel sealing body, and the lower one of the two sealing cavities is an electromagnetic valve sealing cavity. The evacuation valve of the solar water heater has the advantages that the structure is simple, and the use is convenient; as a built-in electromagnetic evacuation valve is arranged in the water tank of the solar water heater, water retained in upper and lower water pipes of the solar water heater can be evacuated, and further, the upper and lower water pipes of the solar water heater can be ensured not to be frozen to be damaged in cold seasons and can be ensured to be normally used.
Description
Technical field
The utility model relates to a kind of exhaust-valve of solar water heater, relates in particular to the built-in electromagnetism exhaust-valve of solar energy that a kind of upper and lower conduit solar water heater is controlled at emptying state.
Background technique
At present, though employed solar water heater is being had a bath and is in lifely being brought too many convenience to people, but, because different areas exists different difference variation, especially northeastward areas such as side, East China, Central China, because winter, outdoor temperature was very low, exterior-wall heat insulation is bad in addition, and the inner wall temperature is in below 0 ℃, water pipe is near wall, more accelerated the transmission of heat, the interior water temperature of pipe is descended gradually, produced and freeze, night, water heater did not use mostly, water in the pipe remains static for a long time, and water temperature descends gradually, until freezing.When ice knot full water pipe section also had certain-length again, water outlet at this moment was blocked, and water heater can't use.
Summary of the invention
According to above deficiency, the purpose of this utility model provides a kind of simple in structure, and built-in Electromagnetically solar energy exhaust-valve easy to use can be drained the water that retains in the solar energy upper and lower conduit, does not influence solar energy in cold season and normally uses.
The technical solution adopted in the utility model is: built-in Electromagnetically solar energy exhaust-valve comprises the interior electromagnet of valve body, spill pipe, emptying pipe and valve body, sensitive switch, solenoid valve push rod, silica gel sealing body, spring etc.Feature is that an electromagnetism exhaust-valve is set in water tank heat-insulation layers, the ball valve of described electromagnetism exhaust-valve is fixed a downward push rod, push rod is passed down through valve body, on the push rod between valve body and the ball valve, overlapping two Seal cages, being the colloidal silica Seal cage that is formed by the silica gel sealing body above, is the solenoid valve Seal cage below.
An extension spring is fixed in the bottom surface of colloidal silica Seal cage, and spring housing is on push rod, and the silica gel sealing body around the spring is made as collapsible, because the silica gel better elastic, the silica gel sealing body is elongated when spring stretches, and the colloidal silica Seal cage still seals intact.
Overlapping an electromagnetic coil on the push rod in the solenoid valve Seal cage, electromagnetic coil is fixed on the top of solenoid valve Seal cage, and the electromagnetic coil side is provided with a sensitive switch, the state that opens or closes of sensitive switch, by the electric wire output signal, realize control and display switch state automatically.A ring electromagnet is set below the electromagnetic coil, and electromagnet is fixed on the push rod, and push rod can move up and down with electromagnet; In the push rod lower end of exposing valve body nut is set.
The exhaust-valve top is provided with an emptying pipe and a spill pipe, and all above horizontal plane in the water tank, spill pipe is communicated with up and down in the upper end of two pipes, and emptying pipe plays a part to go up water and air inlet emptying.
The utility model has the advantages that: simple in structure, easy to use, owing in solar water container, be provided with built-in electromagnetism exhaust-valve, can control and the interior water that is retained of emptying solar energy upper and lower conduit, guaranteed that the upper and lower conduit of solar energy was not damaged by frost and can normally uses in the season of cold.
