Y-type filter transmission medium pipe system is indispensable to a filter device, Y strainer is usually installed in the valve, pressure relief valve, water valve or other device inlet end, used to remove impurities in the medium to protect the valves and equipment normal use. Y-type filter (water filter) has produced a simple, easy to install clean, pollutant carrying capacity and so on. Y-type filter purification equipment works as indispensable a high-efficiency filtration equipment, domestic wastewater, sewage and industrial wastewater treatment have played a great effect; the use in various industries effectively handle a large number of domestic and industrial sewage, make valuable water resources can be effectively reused. Y-type filter is Y-shaped, one end of the water and other liquid through one end of the precipitation of waste, impurities, usually it is installed at the inlet end of the valve, pressure relief valve, water valve or other device, it The effect is to remove impurities in the water, to protect the valves and equipment normal operation, the water to be treated by the filter inlet into the body, impurities in the water are deposited on a stainless steel filter, the resulting pressure differential. And out through the outlet pressure switch monitoring pressure changes, when the pressure reaches the set value, the electric controller to the hydraulic control valve, the drive motor signal to trigger the following actions: motor driven brush rotation of the filter for cleaning, while the control valve is opened the sewage, the entire cleaning process takes tens of seconds duration, when the cleaning is finished, close the control valve, the motor stops, the system returns to its initial state, began to filter into the next step. After installation, the technician commissioning, set the filtration time and cleaning conversion time, the water to be treated by the inlet into the body, the filter starts to work.
