Preferably, it is two right that described standing valve ball and standing valve ball seat are provided with.
Or it is two right that preferably, described travelling valve ball and standing valve ball seat are provided with.
Or preferably, the diameter of standing valve ball is greater than the diameter of flowing valve ball.
Or preferably, described switching pipe nipple stretches out through band umbrella Cone valve to be accepted outside cylinder.
The imbibition of the utility model up stroke, down stroke discharge opeing.Because band umbrella Cone valve is placed in outlet, stop holddown material to enter pump barrel, thus realize anti-sticking.
Accompanying drawing explanation
Fig. 1 is positive view of the present utility model.
In figure, 1-accepts cylinder, 2-is with umbrella Cone valve, 3-support ring, 4-pump barrel, 5-to transfer standing valve seat, 16-upper plate, 17-lateral retaining plate, 18-lower shoe under standing valve ball under travelling valve seat under travelling valve ball under pipe nipple, 6-upper traveling valve cover, 7-upper traveling valve ball, 8-upper traveling valve seat, 9-plunger, 10-, 11-, 12-upper standing valve ball, the upper standing valve seat of 13-, 14-, 15-.
Embodiment
As shown in the figure, the double fixed valve anti-seizing oil pump of the present embodiment by accepting cylinder 1, band umbrella Cone valve 2, support ring 3, pump barrel 4, switching pipe nipple 5, upper traveling valve cover 6, upper traveling valve ball 7, upper traveling valve seat 8, plunger 9, lower travelling valve ball 10, lower travelling valve seat 11, upper standing valve ball 12, upper standing valve seat 13, lower standing valve ball 14, lower standing valve seat 15, upper plate 16, lateral retaining plate 17, lower shoe 18 form.
Accepting cylinder 1 is the main bearing member of this pump, and upper/lower terminal has screw thread, can connected pipes; Pump barrel 4 lower end is welded and fixed with undertaking cylinder 1 by upper plate 16, lateral retaining plate 17, lower shoe 18, and upper end is connected with undertaking cylinder 1 internal surface by support ring 3, forms the outer interior annular space be socketed and arrange between undertaking cylinder 1 and pump barrel 4; Upper plate 16, lower shoe 18 and lateral retaining plate 17 are formed and lead to outside liquid entering hole through accepting cylinder.
Upper standing valve seat 13, lower standing valve seat 15 screw thread are fixed on pump barrel 4 bottom upper and lowerly, and upper standing valve ball 12, lower standing valve ball 14 are sitting on standing valve seat 13, lower standing valve seat 14 respectively, composition oiling valve assembly; Lower travelling valve seat 11 screw thread is fixed on bottom plunger 9; Upper traveling valve seat 8 screw thread is fixed on plunger 9 top, upper traveling valve cover 6 screw thread is fixed on upper traveling valve seat 8, upper traveling valve ball 7, lower travelling valve ball 10 to be sitting on upper traveling valve seat 8, lower travelling valve seat 11 respectively, composition plunger travelling valve assembly, be placed in pump barrel 4, can move in pump barrel 4.
Switching pipe nipple 5 lower end screw thread is fixed on upper traveling valve cover 6, and upper end can be threaded with sucker rod; Band umbrella Cone valve 2 is enclosed within switching pipe nipple 5, there is certain pause between the two.Described band umbrella Cone valve entirety is sitting in pump barrel 4 upper end outlet, and it is made up of the umbrella projection on inverted cone and inverted cone top, and wherein the maximum diameter of inverted cone is greater than the internal diameter of pump barrel, is less than the external diameter of pump barrel; The diameter of umbrella projection is greater than the external diameter of pump barrel, is less than the internal diameter accepting cylinder.
The working principle of the present embodiment is: during up stroke, switching pipe nipple 5 is under sucker rod drives, move up in pump barrel 4 with upper traveling valve cover 6, upper traveling valve ball 7, upper traveling valve seat 8, plunger 9, lower travelling valve ball 10, lower travelling valve seat 11, travelling valve ball sets with on valve seat under stress, form spatial volume by lower travelling valve seat 11, upper fixing all youngster's seats 13 and pump barrel 4 to increase, pressure reduces, standing valve ball 12,14 is depressed outside and is backed down, in oil well, liquid enters in pump chamber from liquid entering hole, realizes imbibition; During down stroke, standing valve ball sets under pressure on fixed valve base, switching pipe nipple 5, upper traveling valve cover 6, upper traveling valve ball 7, upper traveling valve seat 8, plunger 9, lower travelling valve ball 10, lower travelling valve seat 11 move down in pump barrel, fluid pressure in pump chamber is increased, when reaching certain value, back down travelling valve ball 7,10 and band umbrella cone valve 2, pump intracavity liquid upwards enters in oil pipe, realizes discharge opeing; In a word, the same with common tubular type pump work principle, down stroke imbibition, up stroke discharge opeing.
The anti-sticking principle of the present embodiment is: stop holddown material to enter in pump barrel, and allow holddown electrodeposition substance in deposition space.Be embodied as: as Fig. 1, band umbrella Cone valve 2 top becomes umbrella, and diameter is slightly larger than pump barrel 4 external diameter, and lower end is Cone valve, and Cone valve upper diameter is slightly larger than pump barrel 4 internal diameter; Have through hole in the middle of band umbrella Cone valve 2, diameter is slightly larger than switching pipe nipple 5 diameter; Band umbrella Cone valve 2 is enclosed within switching pipe nipple 5, is sitting in pump barrel 4 and exports; During work, band umbrella Cone valve 2 can move up and down along switching pipe nipple 5; When having dirty sheet or other residue sedimentation, when contact zones umbrella Cone valve 2 upper surface, will radially to external diffusion, be deposited to downwards from the edge of umbrella by the annular space formed between undertaking cylinder 1 and pump barrel 4, enter deposition space, thus stop holddown material to enter in pump barrel, and then reduce holddown risk.
