Summary of the invention
Technical problem to be solved in the utility model provides easily high pressure backwash filter station of a kind of filter element replacing.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of high pressure backwash filter station, comprise input duct, the fluid pipeline, triple valve, reversal valve and cartridge assembly, described input duct is communicated with reversal valve by triple valve, reversal valve is communicated with cartridge assembly, cartridge assembly and fluid pipeline communication, described cartridge assembly comprises shell and filter core, described filter core is arranged in the described shell, described filter core upper end is provided with end cap, the inboard, upper end of described shell is fixedly installed screw plug, the upper end is provided with gland in the described screw plug, be provided with quick-connect mechanism between described gland and the described screw plug, described end cap stretches into lower end in the described screw plug, described end cap is positioned at described gland below, be provided with shrinkage pool on the described end cap, described gland center is equipped with screw rod, and described screw rod lower end is stretched into shrinkage pool and withstood on the described end cap.
Inboard, described shell upper end is provided with internal thread, described screw plug is provided with external screw thread, described screw plug is screwed in described shell upper end, described quick-connect mechanism comprises the clamping block that arranges on breach that annular groove, the screw plug upper end in the centre bore that is arranged on screw plug is inboard and the gland, described annular groove communicates with described breach, described clamping block and described notch geometry are complementary, and described clamping block falls in the described annular groove.
The height of described annular groove is slightly larger than the thickness of clamping block, and the centre bore of described gland is provided with screw thread, and when screw rod passed described centre bore and withstands in the described shrinkage pool, the upper surface of clamping block withstood on the upper inner side edge of annular groove.When the upper surface of clamping block withstands on the upper inner side edge of annular groove, can prevent that the gland mistake from opening.
Described breach is three, and it is inboard that evenly annular is distributed in the screw plug upper end, and described clamping block is three, and evenly annular is distributed on the gland.
Be provided with the first sealing ring between shell and the screw plug, be provided with the second sealing ring between screw plug and the gland, be provided with the 3rd sealing ring between screw rod and the gland, prevent that liquid from flowing out.
Be provided with draw ring on the described end cap, the convenient filter core that extracts.
Compared with prior art, the utility model has the advantages that and turn the screw rod certain angle, make the front end of screw rod leave endoporus, this moment, the upper surface of clamping block left the upper surface that presses annular groove, rotated the gland certain angle again, made clamping block and notch alignment, can take out gland this moment in screw plug, screw rod is followed gland and is taken out, thereby filter core can be taken out in shell, and more renew cartridge is very convenient.
