Background technology
Hydraulic system is in use because the fault that medium pollution causes accounts for the great majority of the system failure, along with the automation of the parts course of work is sent out long, the hydraulic system part is more and more accurate, the unit failure rate that requires is more and more lower, therefore, the filtering accuracy that improves system media is the important means that improves Hydraulic System Reliability with preventing in the medium that fifth wheel enters workpiece.
High pressure filtering station with backwashing function is to aim at the medium cleaning device that guarantees the long-time reliability service of hydraulic system and establish.High pressure filtering station is installed on pumping plant outlet, and filter medium pollutant before medium enters work system comprises the metal chip that comes off, seal wear particle, paint, wearing and tearing powder, rubble grain, cinder etc.The cartridge assembly of filter station is most important parts, and cartridge assembly comprises shell and filter core, is provided with internal thread in the shell, is provided with external screw thread on the filter core, and filter core inserts in the shell, and fixes with screw thread.When needs are changed or keep in repair filter core, filter core need to be back-outed in shell, operate cumbersome.Be threaded simultaneously, cause easily and get rusty or stuck phenomenon generation.
Summary of the invention
Technical problem to be solved by this invention provides the easily cartridge assembly of high pressure backwash filter station of a kind of replacing.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of cartridge assembly of high pressure backwash filter station, comprise 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 that it is characterized in that 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.
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.
Be provided with draw ring on the described end cap, the convenient filter core that extracts.
Compared with prior art, advantage of the present invention is to 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.
