Abstract

The invention discloses a pre-filter. The pre-filter comprises an upper cover and a handle sleeve, a handle sleeve is rotatably mounted on a side wall of the upper cover, a filter cylinder is mountedbelow the upper cover, a handle is arranged at the lower end of the handle sleeve, hooks are arranged on two sides below the handle sleeve, a balance ring is arranged above the outer side of the filter cylinder, clamping blocks fitting the hooks are arranged on the balance ring, a flange is arranged at one end in the upper cover, a universal head is rotatably installed on one side of the flange, quick connectors are arranged at two ends of the universal head, water pipes are arranged in the quick connectors, the outside of the universal head is covered with a movable sleeve, a water distribution head is arranged in the upper cover, and a plug valve is arranged in the water distribution head. The hooks on the handle sleeve cooperate with the clamping blocks on the filter cylinder, the handle sleeve is rotated to release the fixation of the hooks and the clamping blocks, so that the filter cylinder can be disassembled to exit from a sealing state of the whole filter, and the filter coreis convenient to replace.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, in particular to a pre-filter. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet of other equipment such as pressure reducing valves, pressure relief valves, and water level valves. The filter is mainly used to block impurities in the conveying medium to achieve purification. the goal of; [0003] Existing filter elements are generally screwed or bolted, which is troublesome to disassemble and inconvenient to replace, and it is difficult to calculate the clean water flow rate of the existing filter, and manual adjustment is required when switching, which is troublesome. Therefore, the present invention proposes A pre-filter solves the problems in the prior art. Contents of the invention [0004] In view of the above problems, the purpose of the present invention is to propose a pre-filter, whi...
