Abstract
The utility model provides a directional formula oil-well pump standing valve that closes by force, comprises spring, sliding valve, sealing washer, slide bar, ball seat, valve cover, fixation nut and lower clutch, the utility model discloses owing to adopted and be the structure that a lower part is hemisphere face, upper portion at the sliding valve, the sliding valve suit is on the slide bar, and the spring suit is on the slide bar, and the lower part has the sealing washer on the sliding valve inslot, cloth on the sliding valve. The slide valve is in reciprocating linear operation on the slide rod, so that the purposes of fixing the oil inlet of the valve and sealing the inner channel and the outer channel of the oil well pump are achieved, even if the oil well pump is horizontally placed, the slide valve can be timely and accurately reset and efficiently sealed, and the applicability, reliability and high efficiency of the oil well pump to different types of oil wells are improved. The utility model discloses novel structure, convenient operation, the reliable operation, very suitable field application.
Description
Technical field:
The utility model relates to the oil well pump that uses on a kind of field produces, and particularly a kind of orientation is closed formula oil well pump standing valve by force.
Background technique:
Existing general oil well pump standing valve is to realize oil-feed and sealed oil-well pump internal and external channel by valve ball up and down reciprocatingly beating in the valve cover.This structural design is fit to straight well and the less oil well of gradient, but use such standing valve to exist the valve ball return to lag behind even can not be sitting in fully on the valve seat for horizontal well and the bigger oil well of gradient, thereby oil well pump standing valve when down stroke can not in time cut out, even lost efficacy, make the oil well pump cisco unity malfunction, reduce pump efficiency, increase energy consumption, influence the normal exploitation of crude oil.
The model utility content:
The purpose of this utility model is to provide a kind of orientation to close formula oil well pump standing valve by force.Adopt the sliding rod type structure, on slide bar, do reciprocal linear movement by guiding valve, realize the purpose of standing valve oil-feed and sealed oil-well pump internal and external channel, even if oil well pump horizontal positioned, can realize that also guiding valve promptly and accurately resets with efficient sealed, has improved applicability, reliability and the high efficiency of oil well pump to dissimilar oil wells.
The utility model is to realize like this, this kind orientation is closed formula oil well pump standing valve by force by spring, guiding valve, seal ring, slide bar, ball seat, the valve cover, hold-doun nut and lower contact are formed, valve cover tip portion is evenly equipped with oil outlet and tapped hole, and be connected with slide bar, in the valve cover lower lumen ball seat is arranged, and be connected with lower contact, uniform oil inlet hole and intermediate throughholes around the lower contact top, slide bar passes through hole, slide bar is the cylindrical body that an outer surface is handled through spraying plating, the upper end links to each other with the valve cover, and lower contact upper end portion center hole and hold-doun nut locking are passed in the lower end, and guiding valve is that a bottom is a hemisphere face, top is a cylindrical structure, slide valve buckle is contained on the slide bar, spring housing is contained on the slide bar, and the bottom is furnished with seal ring on the guiding valve in slide valve slot.
Working principle is: during the pumping unit upstroke, under the effect of pump intake pressure (0.05-0.1Mpa), guiding valve moves upward along slide bar, and pressure spring, this moment, the crude oil in shaft bottom was discharged in the oil well pump pump barrel by the space of lower contact oil inlet hole, guiding valve and ball seat, the oil outlet of valve cover, realized the process of oil-feed.During the pumping unit down stroke, under the double action of guiding valve deadweight and the pre-thrust of spring, guiding valve moves downward along slide bar, and be sitting on the ball seat, passage between sealed oil-well pump pump barrel and the shaft bottom, this moment, the crude oil in the pump barrel was discharged in the above oil pipe of oil well pump piston, so repeatedly, and will be with shaft bottom crude oil extraction ground continuously.
The utility model is that a bottom is that hemisphere face, top are cylindrical structures owing to having adopted at guiding valve, and slide valve buckle is contained on the slide bar, and spring housing is contained on the slide bar, and the bottom is furnished with seal ring on the guiding valve in slide valve slot.On slide bar, do reciprocal linear movement by guiding valve, realize the purpose of standing valve oil-feed and sealed oil-well pump internal and external channel, even if the oil well pump horizontal positioned can realize that also guiding valve promptly and accurately resets with efficient sealed, has improved applicability, reliability and the high efficiency of oil well pump to dissimilar oil wells.The utility model novel structure, easy to operate, reliable operation is well suited for The field.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of spring 1, guiding valve 2, seal ring 3, slide bar 4, ball seat 5, valve cover 6, hold-doun nut 7 and lower contact 8.Uniform six oil outlets and middle tapped hole around valve cover 6 upper end portions, tapped hole is used for being connected with slide bar 4, and the outside, upper end portion is the common tube screw thread, is used for being connected with the oil well pump pump barrel; Also have an annular endoporus in valve cover 6 lower lumen, be used to install ball seat 5, be connected with lower contact 8 by internal thread.Uniform six oil inlet holes and middle through hole around lower contact 8 upper end portions, through hole is used for slide bar 4 and passes, and the bottom is a common tubular type internal thread, is used to connect oil pipe.Slide bar 4 is the cylindrical body that an outer surface is handled through spraying plating, and the upper end links to each other with valve cover 6 by screw thread, and lower contact 8 upper end portion center holes are passed in the lower end, with hold-doun nut 7 lockings.Guiding valve 2 is that a bottom is that hemisphere face, top are cylindrical structures, and the center is a through hole with two annular grooves, handles through spraying plating; Guiding valve 2 is sleeved on the slide bar 4, and gives pre-thrust by the spring 1 that is sleeved on slide bar 4 tops, makes guiding valve 2 do the time spent not being subjected to any external force, can be sitting on the ball seat 5, and can realize sealing.Seal ring 3 plays the effect of auxiliary seal guiding valve 2 and slide bar 4.
