In conjunction with the accompanying drawings embodiment of the present utility model is described below:
In the accompanying drawing, the 1st, clip base, the 2nd, spherical shell gland, the 3rd, sealing mat, the 4th, ball chamber lower plate, the 5,6,11,15, the 16th, sealing ring, the 7th, following spherical shell, the 8th, last spherical shell, the 9th, spray-proof ball, the 10th, following positioning bolt, the 12nd, bulb, the 13rd, club, the 14th, temporary sealing packing, the 17th, sealed packing, the 18th, last positioning bolt, 19 sealing shrouds, the 20th, pressure cap core, the 21st, pressure cap shell, the 22nd, handle.A is the ball chamber, and B is the radial hole of spherical shell gland 2, and C is the location blind hole on bulb 12 spherical outside surfaces, and D is the radial screw bore on club 13 tops, and E is the location blind hole at sealing shroud 19 cylindricals middle part, and F is the cannelure on its cylindrical top, and G is the radial blind holes among the cannelure F.
By accompanying drawing as seen, form tuningout blowout prevention assembly, be in the bottom by component 1～12.Spray-proof ball 9 wherein adopts 101 to strengthen the nylon material manufacturing.There are 12 adjustable degrees of tightness of positioning bolt 10 down of insertion bottle opener in the B hole.Insert the degree of tightness of the adjustable spherical shell gland 2 of rod iron.Following positioning bolt is 4, and its location blind hole C also is 4.14 is the temporary sealing packing, is in the middle part.Form the packing_seal assembly by 13,15～22, be in top.D wherein, E, G hole respectively have 4, and last positioning bolt 18 also is 4.More than three parts be connected to become an integral body by universal spheroid, universal spheroid is formed by 4,12,13.
The planform of universal spheroid and composition as seen from Figure 2.Ball chamber lower plate 4 is welded in bulb 12 lower port, and bulb 12 also is welded into one with club 13.Bulb 12 outer dress sealing rings 5,6,11.
The planform of sealing shroud 19 is adorned sealing ring 15,16 outward as seen from Figure 3.
Each component assemble sequence is: earlier sealing ring 5,6,11 is installed in the seal groove of bulb 12, to go up spherical shell 8 again is inserted in from club 13 tops, and with the installation that matches of the external screw thread of following spherical shell 7, reinstall 4 following positioning bolts 10, make its end insert location blind hole C.Sealing mat 3 is put into down in the seal groove of spherical shell 7.Spherical shell gland 2 is inserted in from club 13 tops, and installation again matches the internal thread of the external screw thread of clip base 1 and spherical shell gland.Blowout prevention 9 is put into from club 13 inner chambers upper end, fallen into ball chamber A.The tuningout blowout prevention assembly of bottom has assembled and has finished at this moment.Again temporary sealing packing 14 is packed into from club 13 inner chambers upper end.Sealing ring 15,16 is installed in the sealing shroud 19 lower seal grooves.With the installation that matches of the internal thread of the external screw thread of sealing shroud 19 and club 13, and make the location blind hole E on the sealing shroud 19 relative, go up positioning bolts 18 with 4 and screw in the radial screw bore D of club 13.The sealed packing 17 of packing into from sealing shroud 19 upper ends.With the installation that matches of the external screw thread on the internal thread of packing pressure cap shell 21 and sealing shroud 19 tops.Integral installation finishes.
Its tuningout centering principle is: clip base 1 is fixed on the well head, under the situation that spherical shell gland 2 does not tighten, spherical shell 8 on it, down spherical shell 7, sealing mat 3, bulb 12, down component such as positioning bolt 10 do as a whole, can circumferential free horizontal movement.When oil pumping polish rod with after polished rod eye is connected with square clamp, the oil pumping polish rod position is if depart from the well head center line, and the tuningout blowout prevention assembly that is enclosed within on the oil pumping polish rod then is offset to same direction with oil pumping polish rod, is unlikely to sealed packing is given birth to eccentric wear, tighten bulb gland 2 this moment, and the horizontal-shift adjustment finishes.Unload Panasonic's positioning bolt 10 with bottle opener, 12 of bulbs can be swung in the certain angle scope with polished rod, adapt to the deflection of oil pumping light to the well head center line automatically, tighten down positioning bolt 10 then, and the angular deflection adjustment finishes.
Its blowout prevention principle is: falls into well head spray-proof ball 9 when oil pumping polish rod because of a variety of causes fracture suddenly and under the well action of hydraulic force, pushed up centre bore lower port to temporary sealing packing 14, firmly can not be up with the well fluid-tight, thus prevented that crude oil from losing and environment pollution.
Its sealing principle is: after spherical shell gland 2 and clip base 1 tightened, the bottom surface contact pressure of sealing mat 3 was bigger.Sealing is tight, and the inclined-plane plays certain self-styled effect to the bottom surface under the effect of fluid, thereby has more guaranteed the excellent sealing of bottom surface.Bulb 12 external surfaces have 3 road sealing rings 5,6,11, also can guarantee excellent sealing.Packing 17 is under the axial compression effect of taper seat on pressure cap core 20 bottom taper seats and sealing shroud 19 bottoms, and both axial compression radially dilated again, and its inner surface is closely contacted with oil pumping polish rod, realizes excellent sealing.
When needs stop production replacing packing 17, counterclockwise rotation fixed handle 22, the F groove that exposes on the sealing shroud 19 gets final product.Lay down 4 with bottle opener then and go up positioning bolts 18, catch on G hole on the sealing shroud 19, clockwise rotate up to temporary sealing packing 14 and play sealing function with the eave tile spanner.Lay down the pressure cap assembly this moment, takes out old packing 17 and change newly, tightens pressure cap again, and with sealing shroud 19 counterclockwise rotations to original position, tighten 4 and go up positioning bolts 18, packing 17 is promptly changed and is finished.
