Product Details

This patent describes a pressure pipeline filter with a timed heating and drain device. It includes an upper filter head, an inlet, a safety valve, a lower filter housing, a filter element, pipe fittings, and a solenoid drain valve. The safety valve is mounted on the upper head near the filter inlet. The solenoid drain valve includes a heater, a timer, a solenoid valve assembly, an impurity inlet, a thermostat, a solenoid valve core, a piston, an air vent, and an automatic drain port. The thermostat is connected to the heater and controls the operating temperature of the solenoid drain valve between 2-5°C. The timer controls the solenoid valve to open once every 6 minutes and maintain the opening for 6 seconds. This product features timed heating and timed draining, solving the problem of impurities and moisture clogging the filter after freezing, while effectively controlling the pollution level of discharged impurities to the outside environment.
