In order to overcome current oil -well pump and to use in highly deviated well, the pump valve easily blocks up, and the leakage is not sternly caused to vice the closing of valve, and the plunger grinds seriously partially for it is not enough that the pump efficiency reduces, the utility model discloses an oil pipe nipple joint, oil pipe coupling, valve bonnet, lower clutch be fixed connection in proper order from top to bottom, installs the disk seat between the interior boss of valve bonnet and the lower clutch, and the valve ball is sat on the disk seat, and valve bonnet upper end fixed mounting has self -cleaning cover, installs spring, spring spindle in the self -cleaning cover from top to bottom in proper order, and the lower extreme of spring spindle is the sphere identical with the valve ball, self -cleaning covering there is radial hole. The beneficial effects are that it is rational in infrastructure, be convenient for make, the dependable performance, closing device is forced in the valve bonnet installation, has and closes rapid characteristics, helps the valve ball in time to seal in highly deviated well, improves the life of pump efficiency and oil -well pump.
Description
Technical field
The utility model relates to a kind of oil well pump of oil development oil recovery production and application, especially relates to a kind of high angle hole standing valve for oil-well pump assembly.
Background technique
Along with the development of oil field development drilling technology, the application of High angle, horizontal well is more and more extensive, also increases both at home and abroad to the demand of High angle oil well pump product thereupon.At present, be applied to the forced opening-closing mode of the wear-resistant employing that high angle hole oil recovery is produced, valve ball is connected with sucker rod, and sealing surface is fixed, and sucker rod drives valve ball to move up and down, and during the closedown of valve pair, impact force is comparatively large, causes the pump valve lost of life.When hole deviation is greater than 65 °, down-hole impurity more easily deposits, and causes standing valve to block, and plunger eccentric wear is serious, and valve pair is not closed completely and causes leakage, and pump efficiency is reduced.Therefore need to research and develop the oil well pump product being more suitable for High angle pumping well, extend the working life of oil well pump.
Model utility content
In order to overcome existing oil well pump use in high angle hole time, pump valve easily blocks, and valve pair is not closed completely and causes leakage, makes the deficiency that pump efficiency reduces, and the utility model provides a kind of high angle hole standing valve for oil-well pump assembly.
The utility model solves the technological scheme that its technical problem adopts: high angle hole standing valve for oil-well pump assembly comprises tubing nipple, tubing coupling, valve bonnet, valve ball, valve seat, lower contact, tubing nipple, tubing coupling, valve bonnet, lower contact are from top to bottom fixedly connected sequentially, between the inner convex platform of valve bonnet and lower contact, valve seat is installed, valve ball is sitting on valve seat, valve bonnet upper end is installed with self-cleaning cover, be provided with spring, spring spindle successively from top to bottom in self-cleaning cover, the lower end of spring spindle is the sphere matched with valve ball; Self-cleaning cover there is radial direction through hole.When valve ball is sitting on valve seat, spring spindle upper-end surface is less than the free height of spring apart from the distance of self-cleaning cover endoporus upper-end surface.Radial direction through hole on self-cleaning cover is inclined hole, the axis of radial direction through hole and below it angle of standing valve axis be 40 °-50 °; The axis of radial direction through hole and below it angle the best of standing valve axis be 45 °.
Valve bonnet is up-small and down-big multidiameter shaft, and tubing coupling is fixedly connected with valve bonnet underpart cylindrical, and the upper end of lower contact is fixedly connected with valve bonnet lower end endoporus.
The beneficial effects of the utility model are, rational in infrastructure, are convenient to manufacture, and start-stop performance is reliable, and valve bonnet installs forced closed device, has and closes feature rapidly, contribute to valve ball and close in time in high angle hole, improve the working life of pump efficiency and oil well pump.
Accompanying drawing explanation
Fig. 1 is the utility model high angle hole standing valve for oil-well pump assembly structure schematic diagram.
In figure: 1. tubing nipple, 2. self-cleaning cover, 3. spring, 4. spring spindle, 5. tubing coupling, 6. valve bonnet, 7. valve ball, 8. valve seat, 9. lower contact, 10. radial direction through hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.But those skilled in the art should know, the invention is not restricted to listed embodiment, as long as spirit according to the invention, all should be included in protection scope of the present invention.
See accompanying drawing 1.The tubing nipple 1 of the utility model high angle hole standing valve for oil-well pump assembly, tubing coupling 2, valve bonnet 3, lower contact 9 are from top to bottom fixedly connected sequentially.The cylindrical of valve bonnet 6 is up-small and down-big multidiameter shaft, and endoporus is up-small and down-big shoulder hole.Tubing coupling 5 adopts screw thread to be fixedly connected with valve bonnet 6 underpart cylindrical, and the upper end of lower contact 9 is fixedly connected with by screw thread with valve bonnet 6 lower end endoporus.Between the inner convex platform and lower contact 9 of valve bonnet 6, be provided with valve seat 8, valve ball 7 is sitting on valve seat.
The upper end of valve bonnet 6 is installed with self-cleaning cover 2, the lower end of self-cleaning cover 2 is blind hole, be provided with spring 3, spring spindle 4 from top to bottom successively in self-cleaning cover 2, the lower end of spring spindle 4 is pressed on valve ball 7, and the lower end surface of spring spindle 4 is the sphere matched with valve ball 7.When valve ball 7 is seated on valve seat 8, spring spindle 4 upper-end surface is less than the free height of spring 3 apart from the distance of self-cleaning cover 2 endoporus upper-end surface, the systolic pressure of spring 3 passes to spring spindle 4 pressure, and state of rest lower valve ball 7 is subject to the effect of spring 3 and spring spindle 4 pressure, is in sealing state all the time.
Self-cleaning cover 2 of the present utility model has radial direction through hole 10, and radial direction through hole 10 is positioned at spring 3 zone of action place.Usual radial direction through hole 10 is inclined hole, the axis of radial direction through hole 10 and below it angle of standing valve axis be 40 °-50 °, best angle is 45 °.
The utility model adopts the strong on-off structure of spring, valve ball can be made to fall after rise in time closed when inclined shaft angle is larger, improves the working life of pump efficiency and oil well pump, is applicable to high angle hole, is especially applicable to containing sand or containing in the High angle oil well of coal dust.
It should be noted that above-described embodiment is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiment and not depart from the right of this patent.
