Adjustable filter head size can be divided according to the length of the filter head skillet (Ⅰ type) and a short handle filter head (Ⅱ type) two. Plates filter head materials imported ABS plastic manufacturing, high bearing strength, step touch is not broken, and strengthen the thread filter head in ABS adjustable filter head structure, solid connection, and never fall off. Plates filter head cap base design to enhance the bottom seam, so with no dead zones between the filter plate, no accumulation of mud, etc., tensile strength for 21-28MPa, impact strength of 27-49kg / cm, a Rockwell hardness of 62-86. Adjustable filter head, skillet filter head, even opened a long slit carefully processed on the filter cap arc, both to prevent leakage of media, but also to ensure a uniform distribution of gas and water distribution. Filter rod is a plastic tube top to open a small hole near the bottom there are two intake crack, compressed air into the space below the water after Plates filter head filter cap, slowly forming a layer of air, and gradually thickens, air layer below the water falling, until the water filter down to the lower part of the long rod intake crack at the time, when the air begins to flow into the crack hole filter rod. When flowing into the air flow through the filter cap and the gap is equal to the flow rate of stream flow away, the water stops declining, stable at a predetermined position, into the air through the filter rod to rise through the filter cap of the filter layer is injected into the gap to go, Plates filter head due to cross multiple spray evenly distributed plum-shaped filter head filter cap purposes, to achieve good backwash effect. Filter head technology requirements: 1) filter head: the filter head for the skillet filter head, by the mushroom type filter cap, filter handle, strong casing, non-toxic rubber gaskets and the like. All components are made in line with "drinking water distribution equipment and protective materials evaluation of health and safety norms" of material production, life of up to 15 years. 2) filter head size: total length of 290mm, slit width 0.3mm, the gap area of ??3cm2, filter rod inside diameter 20mm. 3) filter head structure: filter head filter rod as a whole pyramid filter head filter material, with external thread on the filter handle, the lower thread has Ф2mm holes, the lower end of the handle bar has caught. Embedded sleeve length 100mm, the outer wall of the sealing ring, and with internal thread. Evenly distributed on each filter cap seam filter, filter slit width uniform. Filter head gaps no defects, fly edges and burrs, filter head, smooth surface, no impurities, no cracks, no bubbles, no radial Qu and product shrinkage, industry test standards. 4) filter head Material: ABS plastic, use of materials and real-like consistency ratio must be quoted when, physics of the material, the mechanical properties are required to meet the requirements. Rubber gasket should be a low hardness non-toxic natural rubber.
