Introduction automatic sewage filter-type electronic water meter and electronic water processor filter backwash perfect combination to make the device while both water treatment and filtration, to a machine with two purposes, dramatically reducing equipment costs, save installation space, easy operation and management. Practice has proved that automatic sewage filter-type electronic water meter scientific and reasonable structure, good results, welcomed by users. Works automatic sewage filter-type electronic water meter with electronic water meter and sewage backwash filter functions, including housing, valve plates, bushings, turn the handle, cartridge, water movement and hosts, water treatment machine core located within the cartridge. During normal operation, electronic water meter butterfly plate full, after passing through the filter cartridge is out of the treated water from the inside out through valve plate, dirt is trapped in the filter cartridge (at this time of the connected outfall drain valve closed), When water flows through the water movement, by the high-frequency alternating electromagnetic field treatment, also has Anti-fouling, biocide effect. When dirt accumulation rises, will clog the filter, so that the flow area smaller cartridge, causing the pressure difference between the water flow through the cartridge before and after the increase. When the pressure difference reaches the allowable value, turn the handle, make butterfly plate is off, the water outflow from the inside out front in the cartridge after cartridge segment (residue was collected above) scour the cartridge from the outside to open the drain valve can be discharged slag material. After discharge, close the drain valve, open the handle is reversed, the equipment into normal operation. Features automatic sewage filter-type electronic water meter water meter has both automatic and automatic sewage filter characteristics: ⒈ fully functional: The device has obvious Anti-fouling, biocide, rust corrosion inhibitor, can effectively filter water and dirt, a machine can. ⒉ advanced technology: water processor to run automatically, using intelligent modules complex electric technology, stable performance, powerful, able to automatically adjust the frequency of the output parameters with water, and has a self-diagnostic function. ⒊ economical and practical: the device is not an area, high performance and low cost, easy to install, easy to operate; impact on system operation when sewage is small, do not stop sewage. ⒋ reliable quality: made of imported electronic components, stable performance; rotating shaft mechanical seal, to overcome the shortcomings of traditional packing seal leaky; mesh stainless steel drum to strengthen the structure, difficult to damage. ⒌ green energy: low energy consumption equipment, no pollution, no noise, no special care. Economic environment. ⒍ carefully processed: advanced technology, strict quality assurance system, well-organized, carefully processed to ensure automatic sewage filter-type electronic water meter with leading levels of quality, service life of more than 15 years. Hangzhou Laurel Environmental Technology Co., Ltd. is a commitment to scientific research, production and sales of water treatment equipment, filtration equipment, water industry professional valve manufacturer. There are self-cleaning water filters exhaust, constant pressure water vacuum degassing unit, water processor family, screw degassing decontamination other four series, covering electronic cleaning device, electronic water processor, constant pressure water unit Vacuum Water pressure exhaust unit, the entire integrated water processor, vacuum degasser, tank water processor, next to the water processor, screw degassing decontamination, air impurities spiral separator and so on. http://www.gvguan.net/shuichuli/23.htm
