| titleOfInvention | Polyurethane spraying outer protective pipe spraying integrally-formed prefabricated heat-insulation valve and spraying method |
| abstract | A polyurethane spraying outer protective pipe spraying integrally-formed prefabricated heat-insulation valve and a spraying method. The heat supply pipe network and the pipeline valve adopt the traditional prefabricated direct-buried heat preservation process, the heat preservation foaming is uneven, the outer protective pipe is not spliced and welded thoroughly, the overall heat preservation has great heat loss, and the service life of the heat preservation valve is short. The invention comprises the following components: prefabricated direct-burried heat preservation valve, prefabricated direct-burried heat preservation valve includes the working tube, the horizontal pipe of working tube and vertical tub of skin pass through polyurethane mixing shower nozzle (6) spraying polyurethane protective layer (3) respectively, and leave valve welding interface (1) that do not spray the polyurethane protective layer at the horizontal pipe both ends, the surface of polyurethane protective layer all passes through high-pressure spray gun spraying macromolecular liquid outer jacket (4), polyurethane protective layer internally mounted has a set of alarm line (2), macromolecular liquid outer jacket adopts the density to be 1.2g/cm3 macromolecular liquid elastic material its coating thickness to be 1-20 mm. The invention is used for integrally forming the prefabricated heat-insulation valve by spraying the polyurethane spraying outer protective pipe. |
