Description

The solar water heater defroster
Technical field
The present invention relates to a kind of electromagnetic valve, specifically a kind of solar water heater defroster belongs to water heater winterized equipment field.
Background technology
At present, solar water heater is as the life staying idle at home articles for use, gathered electric heater and gas heater power saving, economize gas, many advantages such as energy-conservation, generally receive people's welcome, also become the most ripe energy-conservation industry of Chinese solar thermal utilization.
When solar water heater uses winter, guarantee that water heater goes out hot water at any time, also can use as usual under the low temperature; Prevent the residual water bursting by freezing pipeline in the yard piping, adopt dual mode usually, a kind of is that the antifreeze facility of outer power is as guarantee; Adopt pipeline to twine the heating tape heating outward, heated 220 volts of voltages in 24 hours; Yet this employing external force means to prevent freezing needs costs such as a large amount of consumptive materials and the antifreeze electricity charge, and present antifreeze consumptive material and installation cost expense thereof account for more than two one-tenth of a complete set of water heater price, and year antifreeze electricity charge are quite a few; When simultaneously heating tape service time, long or quality did not pass a test, will produce fire and electric leakage accident, potential safety hazard is big; Another kind of means to prevent freezing is the tube emptying mode, promptly utilizes magnetic valve to drain the water of pipeline.This method is used magnetic valve more, the many complex structures of magnetic valve that now using, thus manufacturing cost is high; Like the patent No. is the Chinese patent of CN02229814.2, and a kind of solar water heater emptying solenoid valve is in the water inlet of magnetic valve; Increased an air entry, this air entry communicates with delivery port and extends the last inwall place of water butt through external air suction pipe, when the emptying solenoid valve energising is opened; Spool separates with valve face, and water inlet communicates with delivery port through valve face, is in user mode; When the emptying solenoid valve outage was closed, spool was pressed on the valve face, and the cut-out water inlet is connected with delivery port, is in emptying state, and pipeline is through the air-breathing emptying of air entry.This patent need increase an air intake duct and communicate with water butt, and very high to the seal requirement of equipment, and spool also will combine tight with valve body.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of solar water heater defroster, has made full use of existing raw material; Intake-outlet is arranged on the magnetic valve, the water delivery groove is set on spool, control Inlet and outlet water through the control spool; This frost valve is simple in structure, and equipment requirements is lower.
Technical scheme of the present invention is:
