Description
Technical field
The utility model is the filter spool used when a kind of filtering suitable for hydraulic system.
Background technique
Existing hydraulic system host equipment needs be switched on for 24 hours, but needs host when the maintenance and part replacement of equipment
Shutdown could be completed, and this provides for improved production costs, production efficiency are reduced, in order to replace filter core, mesh when not shutting down
It is preceding to use bitubular switch filtering device, since there is one again in actual operation for the central spindle switching construction on bitubular switch filtering device
Lower disadvantage: first is that because central spindle and valve chamber belong to spacing cooperation and firmly to hard cooperation, just will appear if any misoperation switching valve
Stuck phenomenon is unable to complete successfully switching；Second is that not only difficulty of processing is big but also sealing cooperation is bad, easily lets out, cause in appearance
Pollution reduces filter efficiency.
Utility model content
The utility model aim purpose is to provide compact-sized one kind, compact, handover operation conveniently, is not in card
The dead and interior filter spool for letting out phenomenon.
The technical solution of the utility model is completed as follows, it includes a bitubular switch filtering device valve body,
The companion flange of one connection external world oil pipe is installed on valve body top with screw, be equipped on companion flange and is connected in valve body
Oil inlet and oil outlet, a spherical switching spool is installed in oil inlet, is connected with a work in switching spool outer end
Skill plug screw is respectively provided with spool pad in the both ends junction of switching spool, is equipped with one on switching spool before valve body
Control shaft is equipped with switching handle in control shaft outer end, and two filter cylinders connecting with technique plug screw are equipped in valve body lower portion,
Filter core Self-sealing valve is respectively equipped between the filter core and technique plug screw of each filter cylinder.
The utility model is installed a ball valve between two filter cylinders and is switched over, and seal form is sealed using cushion, can
Keep 360 ° of switchings smooth, have it is easy to operate, prevent in let out and stuck advantage.
Detailed description of the invention
Fig. 1 is the structural exploded view of the utility model；Fig. 2 is the assembling schematic diagram of the utility model；Fig. 3 is the A-A of Fig. 2
Schematic cross-sectional view.
Specific embodiment
Embodiment is described in detail in conjunction with attached drawing, it includes a bitubular switch filtering device valve body 2, in valve body top screw
11 are equipped with the companion flange 1 of a connection external world oil pipe, on companion flange be equipped with the oil inlet 1-1 being connected in valve body and
Oil outlet 1-2, is equipped with a spherical switching spool 4 in oil inlet, is connected with a technique plug screw in switching spool outer end
5, it is respectively provided with spool pad 3 and 31 in the both ends junction of switching spool, is equipped with one on switching spool before valve body
Control shaft 9 is equipped with switching handle 10 in control shaft outer end, two filter cylinders connecting with technique plug screw is equipped in valve body lower portion
8 and 81, filter core Self-sealing valve 6 and 61 is respectively equipped between the filter core 7 and 71 and technique plug screw of each filter cylinder.
The utility model can directly switch online, make system non-stop run, and the oil pipe on extraneous host passes through pairing
Flange is separately connected oil inlet and oil outlet, and oil liquid enters from valve body epicoele oil inlet, is switched spool and is directed into seating nipple
Filter core exocoel enters filter core inner cavity after filter layer filters, and enters valve body by filter core Self-sealing valve and enters valve inner flowline
Road enters back into oil supply system after flowing to valve body oil outlet, when the filter cylinder that works reaches specified value, 90 ° of the hand-off handle of rotary cutting rotations
Switching valve, handle instruction point are directed toward spare cylinder direction, and spare filter cylinder filter core chamber opens work.The filter cylinder that works is closed, can be online
Filter cylinder is cleaned and is maintained, for future use.
