Abstract
The invention discloses a high-pressure back-wash filter station which comprises a liquid inlet pipeline, a liquid outlet pipeline, a three-way valve, a reversing valve and a filter cylinder component, wherein the filter cylinder component comprises an outer housing and a filter core, the filter core is arranged in the outer housing, and the upper end of the filter core is provided with an end cover. The high-pressure back-wash filter station is characterized in that the inner side of the upper end of the outer housing is fixedly provided with a plug, the upper end in the plug is provided with a press cover, a quick locking mechanism is arranged between the press cover and the plug, the end cover extends into the lower end in the plug, the end cover is arranged under the press cover, a concave hole is formed in the end cover, a screw rod penetrates through the center of the press cover, and the lower end of the screw rod extends into the concave hole and butts against the end cover. The high-pressure back-wash filter station has the advantages that when the screw rod is screwed by a certain angle, the front end of the screw rod deviates from an inner hole, the upper surface of a locking block deviates and compresses the upper surface of a ring-shaped groove, the press cover is rotated by a certain angle, and the locking block is directed at a gap, so that the press cover can be withdrawn from the plug, the screw rod can be withdrawn along with the press cover, and the filter core can be withdrawn from the outer housing and is very convenient to change.
Description
Technical field
The present invention relates to a kind of filter station, especially relate to a kind of high-pressure back-wash filter station.
Background technique
The fault that hydraulic system in use causes due to medium pollution accounts for the great majority of the system failure, along with the automation of parts working procedure is sent out long, hydraulic system part is more and more accurate, the unit failure rate required is more and more lower, therefore, the filter precision improving system media is the important means improving Hydraulic System Reliability with preventing fifth wheel in medium from entering workpiece.
The high pressure filtering station with backwashing function is the dielectric clean device aiming at the guarantee long-time reliable operation 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 metal and to come off chip, 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 shell, and filter core is provided with outside thread, and filter core inserts in shell, and fixes with screw thread.When needs are changed or keep in repair filter core, need filter core to be back-outed in shell come, operate cumbersome.Be threaded simultaneously, easily cause and get rusty or the generation of stuck phenomenon.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of filter element replacing high-pressure back-wash filter station easily.
The present invention solves the problems of the technologies described above adopted technological scheme: a kind of high-pressure back-wash filter station, comprise input duct, fluid pipeline, three-way valve, selector valve and cartridge assembly, described input duct is communicated with selector valve by three-way valve, selector 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 described shell, described filter core upper end is provided with end cap, screw plug is fixedly installed inside the upper end of described shell, in described screw plug, upper end is provided with gland, quick-connect mechanism is provided with between described gland and described screw plug, described end cap stretches into lower end in described screw plug, described end cap is positioned at below described gland, described end cap is provided with shrinkage pool, described gland center is equipped with screw rod, described screw rod lower end is stretched into shrinkage pool and is withstood on described end cap.
Internal thread is provided with inside described shell upper end, described screw plug is provided with outside thread, described screw plug is screwed in described shell upper end, described quick-connect mechanism comprises the clamping block that breach inside the annular groove be arranged in the center hole of screw plug, screw plug upper end and gland are arranged, described annular groove communicates with described breach, described clamping block and described notch geometry match, and described clamping block falls in described annular groove.
The height of described annular groove is slightly larger than the thickness of clamping block, and the center hole of described gland is provided with screw thread, and when screw rod withstands in described shrinkage pool through described center hole, the upper surface of clamping block withstands 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 gland from opening by mistake.
Described breach is three, and even annular is distributed in inside screw plug upper end, and described clamping block is three, and even annular is distributed on gland.
Be provided with the first seal ring between shell and screw plug, between screw plug and gland, be provided with the second seal ring, be provided with the 3rd seal ring between screw rod and gland, prevent liquid from flowing out.
Described end cap is provided with draw ring, conveniently extracts filter core.
Compared with prior art, advantage of the present invention turns screw rod several angle, the front end of screw rod is made to leave endoporus, now the upper surface of clamping block leaves the upper surface pressing annular groove, then rotates gland several angle, makes clamping block and notch alignment, now gland can be taken out in screw plug, screw rod is followed gland and is taken out, thus filter core can be taken out in shell, and more renew cartridge is very convenient.
