SUPPORTING PARTITION Russian patent published in 2002 - IPC

FIELD: water supply systems for buildings and erections, namely, constructions of heating apparatuses arranged in water supply conduit. SUBSTANCE: supporting partition for tubes of apparatus for heating water includes plate of polypropylene, polysulfone, polyethylene terephtalate or polyamide. Said plate is made, mainly by injection molding with added graphite in quantity 0.1-10 mas.%, preferably in the form of circle having at least one segment, sector, concave arc-shaped or annular cutout. Plate has cylindrical openings with cone inlet portion for placing tubes. Outer diameter of cone inlet portion exceeds diameter of cylindrical opening at last by 0.05 of thickness value of plate wall. Plates of polypropylene containing 0.1-10 mas.% of graphite are made by injection molding in mode providing strength of plate at operational temperature no more than 150 C, at rate of washing out flow up to 5 m/s, at pulsation up to 5% of nominal working pressure not exceeding 16 At. Tubes may be subjected to vibration with frequency no more than 10 Hz. EFFECT: enhanced manufacturability, reliability, increased useful life period, improved operational efficiency of heating and heat exchanging apparatuses. 2 cl, 2 dwg
