Hardware products for HEAT PIPE waterproofed

摘要

The invention relates to the field of mechanical engineering and is used in the manufacture of pre-heat waterproofed products for pipes of different diameters for transporting fluids in underground heating, particularly in hot and / or cold water supply. Set of products for the pipeline comprises heat-waterproofed pipes, including heat-waterproofed Z and U-shaped elements, reducers, elbows, branches, for example, tees, and the heat-waterproofed valves and couplings waterproofing, wherein at least one heat-waterproofed valves from a kit is provided with the waterproofing of the polymer or polymer-based materials in the form of a tube-shell composite shapes from the blanks pipe shells of larger and smaller diameters by cutting a large-diameter opening for the passage of reinforcement elements, and cutting in pritortsevyh zones preform larger diameter cylindrical nonplanar wedges in the form of conditional cylindrical triangle, preferably isosceles, with the conventional base in an end plane of the blank, leaving between each two nearest notches cylindrical lobe as truncated, preferably, transversely of a truncated wedge, and the petals formed height sufficient to form the transition from the socket preform Olsha diameter to a smaller, clamping and compounds, preferably by welding, side faces of adjacent petals and joining, preferably by welding, to a smaller diameter workpieces, while the sum of the lengths of the truncated ends of the petals in the closed position, the lateral faces corresponds to the perimeter of the tubular end connectable with them smaller diameter preform. The technical result achieved technical solution is to provide a set of articles for the heat-damp-proof conduit, the use of which provides long term reliable operation of the pipeline, including at the sites with shut-off and regulating valve with a total ensuring reliable sealing and reducing heat losses on the pipe, due to use products with the claimed sealing parameters, and use as part of a set of declared goods locking and adjusting Armata s, waterproofing sheath which is of high quality while ensuring process simplicity and economy of production. 13 ZP f-ly, 21 Fig.
