Description
Technical Field
The utility model relates to a refrigeration plant filter field especially relates to a self-adaptation filter core type Y type filter.
Background
The primary function of the Y-filter is to filter impurities present in the fluid. In the existing water chiller, a fluid circulation is used for heat transfer, and the circulation is realized by driving the fluid to flow through a water pump. The fluid in this circulation pipeline can produce the foreign matter granule because of various reasons, and the existence of impurity can threaten the water pump for the water pump produces the damage, consequently need install Y type filter additional in the pipeline, filters the foreign matter granule in the fluid that lasts. The existing Y-shaped filter generally comprises a shell, a valve cover, a sealing ring and a filter element, wherein interfaces at two ends of the shell are connected in a pipeline in a welding or threaded connection mode, and the filter element is arranged in the filter through the Y-shaped opening and is sealed and fixed by the valve cover. When the fluid passes through the Y-shaped filter, the filter element filters out impurity particles in the fluid and the impurity particles pass through the clean fluid. The sealing of the filter element mounting end of the Y-shaped filter is realized by screwing the shell and the valve cover through threads to compress the sealing ring, so that the size of the filter element mounted in the filter depends on the machining precision of the shell and the valve cover, the shell and the valve cover are casting parts and have poor size precision, and the shell and the valve cover produced by casting dies in different batches have size difference. This results in a situation where the conventional filter element is deformed by pressure or has a gap when it is installed in the Y-type filter, and thus an accurate matching cannot be achieved. The filter element deforms and risks cracking, and the filter element and the gap affect the filtering effect, so that impurity particles flow into the circulating pipeline through the gap and the gap, and the water pump is damaged.
