The outer wall of described pressure head is coated with ceramic layer.
Described stripper rubber adopts air filling type or pressure head compression type.
Described flexible member is back-moving spring.
Described main body, connector, protective sleeve, stripper rubber, pressure head are on same central axis.
The beneficial effects of the utility model: this abrasion-proof oil conduit blanking plug that the utility model provides; structure is simple; convenient and practical and long service life; the problem of stripper rubber wearing and tearing is solved by the use of protective sleeve; and the input with the use of the control and blanking plug that make protective sleeve of protective sleeve and latch is same process; further enhance the protected effect of stripper rubber and do not affect the expansion of stripper rubber, finally also being thrown in by weighted lever, improve homework precision.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is the structural representation of abrasion-proof oil conduit blanking plug.
Description of reference numerals: 1, slips; 2, main body; 3, protective sleeve; 4, stripper rubber; 5, flexible member; 6, pressure head; 7, ceramic layer; 8, steel wire; 9, latch; 10, bumper jar; 11, connector.
Detailed description of the invention
Further the abrasion-proof oil conduit blanking plug that the utility model provides is described in detail below with reference to accompanying drawing.
embodiment 1:
In order to the problem that the stripper rubber solving existing tubing plug is easily worn, as shown in Figure 1, the utility model provides a kind of abrasion-proof oil conduit blanking plug, comprise main body 2, main body 2 is provided with slips 1, one end and the main body 2 of slips 1 are rotationally connected, one end is connected with main body 2 by slide block in addition, one end of main body 2 is connected with pressure head 6, other one end of described main body 2 is connected with connector 11, connector 11 is circumscribed with bumper jar 10, connector 11 is radially provided with latch 9, latch 9 inserts the pin hole on connector 11 through bumper jar 10, main body 2 is arranged with stripper rubber 4 on the outer wall near pressure head 6 one end, the outer wall of stripper rubber 4 is arranged with protective sleeve 3, the inwall of protective sleeve 3 is connected by steel wire 8 with between latch 9, flexible member 5 is connected with between protective sleeve 3 and the end away from the pressure head 6 of main body 2.
Concrete, connector 11 is circumscribed with bumper jar 10, latch 9 inserts in the pin hole of connector 11 through bumper jar 10, its effect makes operating personnel that weighted lever can be utilized to connect bumper jar 10 to throw in tubing plug, bumper jar is utilized to strike off latch to complete input when operating personnel think after input puts in place, avoid existing use cement pump truck and tubing plug is delivered to intended pipe position, the problem accurately cannot determining tubing plug position caused;
It should be noted that, at part oil pipe coarse or band sand oil field exploitation in find, the stripper rubber of existing tubing plug is directly outside exposed, easily be worn, in order to solve the problem, the main body 2 of the abrasion-proof oil conduit blanking plug that the utility model provides is arranged with stripper rubber 4 on the outer wall near pressure head 6 one end, the outer wall of stripper rubber 4 is arranged with protective sleeve 3, the inwall of protective sleeve 3 is connected by steel wire 8 with between latch 9, flexible member 5 is provided with between protective sleeve 3 and the end away from the pressure head 6 of main body 2, its effect is, by steel wire 8, protective sleeve 3 is temporarily fixed on stripper rubber 4 outer wall, can not damage because of stripper rubber 4 and tubing wall friction when throwing in, when by the flexible member 5 struck off on rear pressure head 6, protective sleeve 3 being pulled to pressure head 6 because of latch 9 after input, thus expose stripper rubber 4.
