A novel multi-medium switching cooling pipeline and its use method

Abstract

The present invention relates to the technical field of PVC calendering film production equipment, and specifically, to a new type of multi-media switching cooling pipeline and a method of use, including multiple groups of water supply and return pipelines and multiple groups of distributor groups, multiple groups of water supply and return pipe groups and multiple groups of cooling roller groups connected to each other, the distributor groups, the water supply and return pipe groups correspond to each other and are connected to the cooling roller groups, and the water supply and return pipe groups include water supply pipes, water return pipes, switching valves, branch hoses 1, branch hoses 2 and U-shaped hoses that are connected to each other. The method of use of the multi-media switching cooling pipeline includes a method of switching each medium and a method of connecting a U-shaped water supply mode, a W-shaped water supply mode and a W-shaped backwashing mode. The present invention has a simple and reasonable structure, is easy to use, and can switch the medium accurately and quickly, avoiding various adverse effects caused by switching errors; it provides a variety of water supply modes, improves the cooling effect, can perform backwashing, and improves the cooling effect and the service life of the equipment.
