Description

Filter convenient to dismantle filter core Technical Field The utility model relates to the technical field of filters, in particular to a filter with a filter element convenient to detach. Background The filter is an indispensable device on the conveying medium pipeline, is usually arranged on a pressure reducing valve, a pressure releasing valve and a fixed water level valve, is convenient for inlet end equipment of other equipment of the filter, and can be filled again after being provided with a filter cylinder with a certain specification of filter screen, and impurities are blocked. But when many filters need to be replaced, the disassembly process of the filter element is complicated, and the filter body needs to be disassembled from the installed equipment to conveniently disassemble the filter element, so that great trouble is brought to the replacement work of the filter element. In view of the above, the present utility model proposes a filter that facilitates the removal of the cartridge. Disclosure of utility model The utility model provides a filter with a filter element convenient to detach, which solves the problems that the filter element is convenient to detach only by detaching a filter body from installed equipment when the filter element needs to be replaced in many filters in the prior art, and the replacement of the filter element is very troublesome.
