Abstract

A related secondary reverse-flow type filtering joint comprises a swirling separation part, a conflux separation part and a reverse flow part; the swirling separation part rotates a fluid mainly through a main body provided with a spiral swirling tank, so that impurities with different mass are separated; the fluid is subjected to secondary separation filtration in a separation assembly with a gradually divergent opening in the conflux separation part; and then the reverse flow part enables impurities deposited in the separation assembly to flow back to the swirling separation part through a liquid flow. Therefore, secondary separation and secondary reverse flow of the fluid are realized through the simple structure, obstruction of the conflux separation part caused by excessive impurities is effectively prevented, and the secondary reverse-flow type filtering joint is convenient to mount and low in cost.

Description

technical field [0001] The invention relates to a secondary backflow filter joint, in particular to a liquid joint capable of filtering trace impurities and irrelevant mixtures. Background technique [0002] In many fluid equipments that require high water quality, such as steam drums in boilers, distillers, and some chemical equipment, it is not only often necessary to filter water, but also these equipments often produce Scale, especially at the pipe joints, is particularly prone to blockage due to scaling or dirt accumulation. Whether it is impurities or blockage, it will bring certain safety hazards to these pressure reaction equipment; [0003] Therefore, at the joints of these equipment with high water quality requirements, it is necessary to install some filter components that can not only have a filtering effect, but also ensure a certain fluid permeability; [0004] Among them, ZL201320354014.4 proposes a pipeline filter joint, which has relatively high requirement...
