Double filter, also known as parallel double switching filter (hereinafter referred to as double filter), is composed of two single-cylinder filters and full-bore three-way ball valve. It has a simple structure and is easy to use.
During the working process, when the filter element of the single-cylinder filter is blocked to a certain extent and needs to be cleaned or replaced, the main engine should be stopped to replace the filter element, which will not only waste time, but also cannot meet the needs of continuous operation of the main engine.
The filter effectively solves the shortcomings of the single-cylinder filter. The double filter has a novel and reasonable structure, good sealing performance, strong flow capacity, low probability of side leakage of the filter element, can accurately ensure the filtration accuracy, and can quickly replace the filter element. labor costs.
