Abstract
The utility model discloses an internal blowoff valve of a solar water heater, which comprises a heat-resistant food-grade shell, a direct-current speed reducing motor, a driving chamber case, a crankshaft, a connecting rod, a limiting switch, a diode, a draining pipe, a seal rubber ring, a motor bracket, a motor support, a fastening screw, a pressurizing spring and a waterproof jacket which are connected in sequence. The internal blowoff valve penetrates though a water tank from the upper part of the water heater to the lower part; the blowoff valve body is well insulated inside the water tank; and a driving chamber is arranged above the water tank, thus avoiding that parts are clamped or damaged due to high temperature. The driving mechanism, the draining pipe and the seal rubber ring can be detached when the solar water heater is not used for draining water, therefore, the internal blowoff valve is convenient to maintain and use. The internal blowoff valve has the benefits of enabling the solar water heater to drain hot water after being turned on in winter, solving the problem of the traditional solar water heater that hot water is drained after cold water, saving water resources, dispensing with a tracing band heating pipeline, having a simple structure, and being convenient to use.
Description
Affiliated technical field:
The utility model relates to the problem in frozen pipe road no longer in solar water heater winter, once having opened hot water.
Background technology:
At present, known solar water heater to winter the upper and lower conduit road freeze stifledly easily, install the easy initiation fire of heating tape additional, also waste the water source get off because will put a lot of cold water during water.Install external exhaust-valve additional, freeze stifledly easily with the water tank junction, also easy-maintaining not is integrated because valve has built up, and also will put the water in the water heater only during maintenance.
Summary of the invention:
The purpose of this utility model provides the built-in emptying system of a kind of solar water heater, and the start instant-heating and outlet hot overcomes the problem of prior solar water heater pipe freezeup in winter.The utility model solves its technical problem: be the shell by high temperature resistant food-grade, direct-flow deceleration electric motor, drive chamber's shell, bent axle, connecting rod, limit switch, diode, evacuated tube, O-ring seal, motor supporting plate, support of motor, holding screw, pressurized spring, waterproof jacket are linked in sequence.It is characterized in that: driving mechanism is connected with bent axle, connecting rod, evacuated tube, O-ring seal, exhaust-valve shell, and driving mechanism is connected with indoor controller.On cylindrical exhaust-valve shell, be provided with air admission hole, paddle hole, water inlet pipe and water outlet pipe, bent axle is embedded on the motor, and gag lever post is installed on the bent axle, and connecting rod links to each other with bent axle, evacuated tube, evacuated tube is provided with air admission hole, columniform O-ring seal is installed in the evacuated tube bottom, and cylindrical pressurized spring is installed in evacuated tube inside, near connecting rod, cylindrical telescopic rubber waterproof cover is installed on holding screw and the evacuated tube, and the motor drives evacuated tube moves up and down.Motor turns round clockwise during water, and bent axle moves to the top dead centre limit switch and closes, and backward diode is logical, and motor stops, and O-ring seal is opened, normal water.Motor turns round counterclockwise during emptying, and the stop limit switch cuts out under the bent axle operation, and backward diode is logical, and motor stops, and O-ring seal is closed, and the evacuated tube air inlet reaches the purpose of tube emptying.The utility model is by running through water tank to the bottom above the water heater, the emptying valve body is good at the internal insulation of water tank, and drive chamber has avoided parts to be subjected to the phenomenon that temperatures involved is stuck, damage on water tank.Driving mechanism, evacuated tube, O-ring seal are detachable under the situation that solar water heater does not discharge water, and are convenient to maintenance, and be easy to use.
The beneficial effects of the utility model are: solar water heater in the winter time-Kai just has hot water, solved traditional solar water heater, put a little cold water earlier and get off, after the problem that puts hot water, save the water source, no longer use the heating tape water back, simple in structure.
