Abstract
The utility model relates to a detaching device of a valve seat of a water injection pump. The valve seat is mounted in a cylinder sleeve, the inner hole of the valve seat is conical, the lower part of an expansion block is inserted into the inner hole of the valve seat, the expansion block is mounted at the window of an expansion block seat, the upper part of the expansion block seat is fixedly connected with the lower part of a detaching rod, the detaching rod is sheathed outside an expansion rod, the lower part of the expansion rod is tapered, the inner wall of the lower part of the expansion block is in contact with the tapered lower part of the expansion rod, the detaching rod penetrates through a cross beam, the cross beam is placed into the upper port of the cylinder sleeve, a positioning rod is transversely mounted on the cross beam, a thread at the upper part of the detaching rod and a detaching nut are screwed down, the thread at the upper part of the expansion rod and an expansion nut are screwed down, the expansion nut is screwed for moving the expansion block outward, the tapered circular arc surface outside the lower part of the expansion block is used for hanging the valve seat, the detaching nut is further screwed, the detaching rod, the expansion block seat and the expansion block move upward, and the valve seat is pulled out of the cylinder sleeve. Therefore, the detaching device can conveniently and quickly detach the valve seat, the labor intensity of a worker is low, the working efficiency is high, the valve seat is not damaged, the working quality is good and the economic benefits are significant.
Description
Technical field:
The utility model is the instrument that water-flooding pump for oil field is repaired usefulness, is the dismounting device of a kind of water injection pump valve seat.
Background technique:
During oilfield water extraction, squeeze in the stratum after needing to inject the water supercharging, the valve seat of water injection pump needs frequent dismounting, because water injection pump works under hard conditions; It is dead that valve seat is easy to rust, because the space is narrow and small, valve seat is not quick detachable again; Adopt time-consuming, the effort of existing instrument dismounting valve seat, damage valve seat easily, workmanship is poor; Cause the water injection pump cisco unity malfunction sometimes, influence field produces, produce heavy economic losses.
Summary of the invention:
The purpose of the utility model provides the dismounting device of a kind of water injection pump valve seat, can dismantle the water injection pump valve seat easily and efficiently.
The purpose of the utility model is achieved in that and comprises swelling nut, dismounting nut, location crossbeam, positioning rod, removal rod, swelling block, expanding block, valve seat, swelling bar, cylinder sleeve, and valve seat is installed in the cylinder sleeve, and it is conical that the valve seat endoporus is; Upper end diameter is little, and lower end diameter is big, and insert in the valve seat endoporus expanding block bottom; Expanding block bottom external conical shape arc face and valve seat endoporus match, and expanding block is installed in the window place of swelling block, and swelling block top is connected fixing with the removal rod bottom; Removal rod is sleeved on outside the swelling bar, and swelling bar bottom is taper, and the expanding block lower inner wall contacts with swelling bar lower taper; Removal rod passes crossbeam, and crossbeam is put into the cylinder sleeve upper end-hole, and positioning rod laterally is installed on the crossbeam; Removal rod top screw thread and dismounting nut driving, swelling bar top screw thread and swelling nut driving.
The beneficial effect of the utility model: screw the swelling nut expanding block is outwards moved, expanding block bottom external conical shape arc face tangles valve seat, screws the dismounting nut again; Removal rod, swelling block, expanding block are up, valve seat are extracted in cylinder sleeve, therefore; The utility model can be dismantled valve seat easily and efficiently, and labor strength is low, high working efficiency; Do not damage valve seat, workmanship is good, has remarkable economic efficiency.
Description of drawings:
Accompanying drawing 1 is the utility model embodiment's a erection drawing.
Embodiment:
Below in conjunction with Fig. 1 the utility model embodiment is described.
Can be known that by Fig. 1 the embodiment of the utility model comprises swelling nut 1, dismounting nut 2, location crossbeam 3, positioning rod 4, removal rod 5, swelling block 6, expanding block 7, valve seat 8, swelling bar 9, cylinder sleeve 10, valve seat 8 is installed in the cylinder sleeve 10; Valve seat 8 is worked in cylinder sleeve 10, and it is conical that valve seat 8 endoporus are, and upper end diameter is little; Lower end diameter is big, and insert in valve seat 8 endoporus expanding block 7 bottoms, and expanding block 7 bottom external conical shape arc faces and valve seat 8 endoporus match; Expanding block 7 is installed in window 11 places of swelling block 6, and window 11 has 3-4, is evenly distributed on the swelling block 6; Each window is installed an expanding block 7 for 11 li, and window 11 makes expanding block 7 can only inwardly outwards move and can not upwards move down with respect to swelling block 6, and swelling block 6 tops are connected fixing with removal rod 5 bottoms; Firm welding again after being threaded, removal rod 5 is sleeved on outside the swelling bar 9, and swelling bar 9 bottoms are taper; Expanding block 7 lower inner wall contact with swelling bar 9 lower taper, and removal rod 5 passes crossbeam 3, and crossbeam 3 is put into cylinder sleeve 10 upper end-hole; Positioning rod 4 laterally is installed on the crossbeam 3, and positioning rod 4 makes crossbeam 3 be positioned at the upper end-hole of cylinder sleeve 10, can be stuck in after stretch out positioning rod 4 outer ends on the male member of polymer-injecting pump crossbeam 3 is not rotated; Removal rod 5 top screw threads are screwed with dismounting nut 2, and when screwing dismounting nut 2, removal rod 5 is up; When screwing swelling nut 1, swelling bar 9 is up, and swelling bar 9 top screw threads and swelling nut 1 are screwed.
Before expanding block 7 was packed in the valve seat 8, expanding block 7 lower inner wall can not contact with swelling bar 9 lower taper, expanding block 7 can in move; Its boundary dimension is diminished can get in the valve seat; Screw swelling nut 1 then, expanding block 7 lower inner wall are contacted with swelling bar 9 lower taper, expanding block 7 outwards moves under conical surface effect; Expanding block 7 bottom external conical shape arc faces tangle valve seat 8; Screw dismounting nut 2 again, removal rod 5, swelling block 6, expanding block 7 are up, and valve seat 8 is extracted in cylinder sleeve 10.
