Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Shown by Fig. 1, Fig. 2, a kind of hydraulic pressure bush extractor, including cylinder body 1, top is provided with piston 9, cylinder at the center of cylinder body 1
Sealing ring is provided between body 1 and the side wall of piston 9, cavity is provided between the bottom surface of piston 9 and cylinder body 1；The upper outside of cylinder body 1 is connected with
Overcoat 6, cylinder body 1 are provided with upper lid 7 with the top of overcoat 6, a cavity are formed between such cylinder body 1 and overcoat 6.The bottom of cylinder body 1
Portion is provided with oil drain passage 3 and suction passage 4, and the two end is designed with plug 2, and wherein oil drain passage 3 leads to the bottom surface of piston 9 and cylinder
Cavity between body 1, the cavity that suction passage 4 is led between overcoat 6 and cylinder body 1.The oil drain passage 3 and suction passage 4 it
Between be connected by sprue, and needle-valve 5 is connected with sprue, when needle-valve 5 is opened, is connected by oil drain passage 3 and suction passage 4
It is logical.Plunger case 12 is fixed with the cylinder body 1, the inside of plunger case 12 is provided with plunger 11, and the inner chamber of plunger case 12 passes through secondary channels 13
It is connected with oil drain passage 3 and suction passage 4.The secondary channels 13 are provided with the check valve for flowing to oil drain passage 3, i.e. liquid stream can only
Oil drain passage 3 is flowed to by secondary channels 13；Suction passage 4 is provided with the check valve for flowing to secondary channels 13, i.e. liquid stream can only be by oil suction
Passage 4 flows to secondary channels 13.The top of plunger 11 is connected with depression bar 10, and the activity of plunger 11, institute are controlled by manipulating depression bar 10
State the top of lid 7 and be fixed with drop handle 7, can integrally be lifted the hydraulic pressure bush extractor by drop handle 7.
When needing to take out valve seat, valve seat is fixed on piston 9, closes needle-valve 5；Lift plunger 11, then oil suction
Check valve on passage 14 is opened, and hydraulic oil is inhaled into secondary channels 13 and the cavity of plunger case 12 by suction passage 4；Push
Plunger 11, the then closed check valve in suction passage 14, the check valve in secondary channels 13 are opened, the hydraulic pressure in the cavity of plunger case 12
Oil by secondary channels 13 flows to oil drain passage 3, eventually flows to the cavity between the bottom of piston 9 and cylinder body 1, so that by piston top
Rise.It is anti-must lift, depresses plunger 11, most at last valve seat take out.After the completion of work, needle-valve 5 is opened, then suction passage 4 and row
Oily passage 3 connects, and plunger case 12 completes pressure release, and plunger 11 returns to original position.
