Filter head should be evenly arranged on the filter plate, filter head installed before the filter plate, filter head casing embedded design size requirements shall be in accordance with the pre-buried in the filter plate. When installing the filter head and tighten that concrete can, filter head mounting pitch is generally not less than 100mm. Must be used when pouring concrete mold steel filter plates, according to design requirements, the first fixed filter head embedded casing, casing embedded vertical error of not more than twice. Concrete should be high-grade cement, Ф10mm bidirectional double rebar reinforcement steel. Concrete grade should be greater than C25, the filter plate plane error of ± 1mm. Features adjustable filter attempts to prevent head: blockades adjustable filter head filter plate used in conjunction with the whole cast, especially for the water to the V-filter, filter flap and BAF sewage treatment on both solve the problem of clogged filter head, but also solve the poor performance of the filter plate sealed filter head, the problem of low intensity, but also to solve the technical difficulties installing the filter head Plates level difficult to achieve. 1, with both ends of the filter cap structure under bidirectional filter head, sewage in the SS is the next filter cap closure, but completely solved easily clogged filter head hidden; 2, having the filter rod adjustment function, a fundamental solution to the Plates in the whole cast or installation process due to irregularities caused by the intake inconsistent risks; attempts to prevent the type of filter head BAF dedicated technical requirements specification data; ⑴ blockades type BAF special filter head with filter cap from the filter rod, embedded casing and attempts to prevent the filter cap consisting skillet filter head specifications, embedded in the concrete filter plate embedded in the casing, and with an internal thread, filter plate thickness 100mm. (2) filter head, filter tubes and embedded casing properties are consistent with the provisions of "drinking water compared with standard equipment and safety evaluation of protective materials" GB / T17219 in. (3) high pressure filter head promise, stepped touch is not broken, reliable connection, after installation shall ensure that the head does not fall off the filter. (4) between the filter head and filter plate should be no dead zones, do not plug the plot mud. (5) attempts to prevent the type of filter head BAF special quality inspection standards; filter head gap should be no defects, fly edges and burrs, filter head surface should be smooth, no impurities, no cracks and drainage water treatment filter cap filter head cap hat, no bubbles, consistent surface color, dip shiny surface, the product without flexing phenomenon, no shrinkage, no lack of material phenomena. According to specifications, is not greater than ± 0.1mm.
