Description
Technical field
The utility model relates to a kind of combined types to suppress plug.
Background technique
Whether hydraulic multichannel conversion valve etc. is normal in order to test its performance when repairing, and usually requires to carry out bulge test.
When carrying out bulge test, in general, needing first to remove the pipe fitting at hydraulic multichannel conversion valve plate valve oil inlet and oil return mouth, then use
Plug blocks the oil inlet and oil return mouth of hydraulic multichannel conversion valve plate valve, accesses oil inlet and oil return in hydraulic multichannel conversion valve oil inlet and oil return module later
Pipe, is passed through high pressure oil, tests the good of each plate valve of hydraulic multichannel conversion valve finally by the handle of manipulation hydraulic multichannel conversion valve
It is bad.Since the plate valve of hydraulic multichannel conversion valve is more, the pipe fitting quantity used is more, and test requires to dismount primary pipe every time
Connect and Choke Plug, heavy workload, consuming time is long, low efficiency.
Summary of the invention
The utility model is intended to overcome the shortcomings of above-mentioned prior art, provide it is a kind of it is versatile, can save the plenty of time
Plug is suppressed with the combined type of manpower.The plug is used directly for blocking the pipe fitting of plate valve on hydraulic multichannel conversion valve, and
It does not need to remove pipe fitting.
It includes U-nut, hemispherical plug and connecting rod, gasket and adjusting pad that the utility model combined type, which suppresses plug,；
Connecting rod be it is cylindric, connecting rod is fixed on hemispherical plug upper end planar central position, and connecting rod and upper transverse plane are perpendicular；U-shaped spiral shell
A circular hole is provided at female upper end center, Circularhole diameter is slightly larger than connecting rod diameter, and U-nut lower end inside has internal screw thread；Adjustment
Pad, gasket are successively sleeved on connecting rod lower end, and gasket is located above adjusting pad, can assist compressing adjusting pad and play sealing envelope
The effect of oil；U-nut upper end center circular hole covers on connecting rod, and gasket, adjusting pad, hemispherical plug are respectively positioned on U-nut
It is interior.
In use, upper adjusting pad, gasket, U-nut are successively covered on hemispherical the upper part of the plug cylindrical connecting rods, by U
Shape nut is screwedly mounted on the pipe fitting of tested hydraulic multichannel conversion valve plate valve by its lower end internal screw thread；In U-nut lower end
Screw thread matches with pipe fitting upper external screw thread size；Pipe fitting both ends are external screw thread, and there are through-hole, through-bore axis and screw thread in centre
Axis is overlapped；The lower end of pipe fitting is screwed into the oil inlet and oil return hole of hydraulic multichannel conversion valve plate valve, and upper end access said combination formula is beaten
Press plug；After all pipe fittings of tested hydraulic multichannel conversion valve plate valve suppress plug blocking using said combination formula,
Oil inlet pipe is accessed on the oil inlet of multiple directional control valve oil inlet and oil return module, accesses oil return pipe on oil return opening；Oil inlet pipe is returned for high pressure oil
Oil pipe accesses fuel tank；After oil inlet pipe feeds high pressure oil, successively manipulates plate valve handle and commutate, it can test all hydraulic is more
The performance of way reversing valve plate valve.
The utility model is suitable for various the case where needing clogging hydraulic element affiliated pipe fitting oil circuit mouth, its advantage is that knot
Structure is simple, and combination is convenient, and practical and applicability is good, and the workload of pipe fitting is dismounted when reducing test Hydraulic Elements；It can
It is directly used in the pipe fitting for blocking plate valve on hydraulic multichannel conversion valve, without removing pipe fitting, is preferably resolved existing
Suppress heavy workload brought by mode, the problems such as consuming time is long.
Detailed description of the invention
Fig. 1 is hydraulic multichannel conversion valve structural schematic diagram；
Fig. 2 is to suppress test attachment structure schematic diagram using the utility model；
Fig. 3 is that the utility model combined type suppresses stopper structure schematic diagram；
In figure: 1. plate valve handles, 2. hydraulic multichannel conversion valve plate valves, 3. oil inlet and oil return mouths, 4. plugs, 5. pipe fittings, more than 6.
Way reversing valve oil inlet and oil return module, 7. oil inlet pipes, 8. oil return pipes, 9. combined types suppress plug, 10. U-nuts, 11. gaskets,
12. hemispherical plug, 13. connecting rods, 14. adjusting pads.
Specific embodiment
Corresponding U-nut 10 and dome-type plug 12 are selected according to 5 exposed threads of pipe fitting and sealing groove mouth size,
Adjusting pad 14, gasket 11 and U-nut 10 are successively put on the cylindric connecting rod 13 in the rear portion of dome-type plug 12, assembling is in groups
It is box-like to suppress plug 9, then combined type is suppressed into the installation of plug 9 and is tightened in oil inlet and oil return on tested hydraulic multichannel conversion valve plate valve 2
On the pipe fitting 5 installed on mouth 3.Plug 4 suppresses plug 9 using combined type.
When suppressing plug 9 using combined type and suppressing test to hydraulic unit, U-nut 10 is twisted by its lower end internal screw thread
On the pipe fitting 5 of tested hydraulic multichannel conversion valve plate valve 2；Spiral shell outside 10 lower end internal screw thread of U-nut and 5 upper end of pipe fitting
Line size matches；5 both ends of pipe fitting are external screw thread, and there is through-hole in centre, and through-bore axis is overlapped with the axis of thread；Pipe fitting 5
Lower end is screwed into the oil inlet and oil return hole 3 of hydraulic multichannel conversion valve plate valve 2, and upper end access said combination formula suppresses plug 9；Tested solution
Press multiple directional control valve plate valve 2 all pipe fittings 5 using said combination formula suppress plug 9 block after, multiple directional control valve into
Oil inlet pipe 7 is accessed on the oil inlet of oil return module 6, accesses oil return pipe 8 on oil return opening；Oil inlet pipe 7 connects for high pressure oil, oil return pipe 8
Enter fuel tank；After oil inlet pipe 7 feeds high pressure oil, successively manipulates plate valve handle 1 and commutate, test all hydraulic multi-way reversing valve block
The performance of valve 2.After the completion of entire bulge test, then combined type is suppressed into plug 9 and is removed.
