Transverse slat 175 is unclamped, is mutually blocked between the limited block 173 and limit plate 162 of reset, 12 length of telescoping tube remains unchanged；
After the present invention is connect with pipeline: liquid can be mixed with large granular impurity when flowing, and liquid washes strainer 231 open, greatly
Granule foreign is stopped by cartridge filter 21, and large granular impurity has stayed between circular filter screen and filter screen 22；
When disassembly: pressing compression leg 166, adjustable plate 164 drive connecting rod 163 to move back, and connecting rod 163 drives 162 angle of limit plate
It adjusting, limit plate 162 no longer blocks limited block 173, and limited block 173 is popped up far from empty slot, and 12 length of telescoping tube is adjustable, it
Afterwards, screw thread outer cylinder 421 reversely pushes, and no longer clamping between fixture block 422 and detent block 413 rotates backward connection screw thread mouth 423,
Connection screw thread mouth 423 is disassembled from external pipe, and later, by unidirectional filter 2, individually disassembly carries out internal remove contamination.
Workflow in summary, solve existing check-valves need to rotate check-valves itself come with external pipe into
Row connection, when installation and removal, due between the pipeline on both sides there are distance it is relatively narrow, existing check-valves is difficult to install and tear open
It unloads, for existing check-valves in use, the liquid of flowing inevitably has large granular impurity, when long-term flowing can be difficult by line clogging
With problems such as cleanings, purpose is reached.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
