Reference character:
1, pump barrel; 2, plunger; 3, the second valve seat; 4, the second valve ball; 5, the first valve seat; 6, the second valve ball; 7, the first cyclone structure; 8, the second cyclone structure.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
As shown in Figure 1, the utility model that the utility model provides provides a kind of tubing pump, comprises pump barrel 1 and plunger 2; Pump barrel 1 is tubular structure, and bottom is insinuated into treats in pumping crude oil, and it is ring structure that the inside of pump barrel 1 is provided with the first valve seat 5, first valve seat 5, and center is provided with the first through hole, fixes and be tightly connected between the outer rim of the first valve seat 5 and the inwall of pump barrel 1; Be positioned at above the first valve seat 5 and be provided with the first valve ball in pump barrel 1, the diameter of the first valve ball is greater than the diameter of the first through hole, the first valve ball is used for coordinating with described first through hole forming shutoff.
Plunger 2 is tubular structure, to be plugged in pump barrel 1 and to be positioned at the top of the first valve seat 5, the outer wall of plunger 2 is connected with the inwall slipper seal of pump barrel 1, the inside of plunger 2 is provided with the second valve seat 3, second valve seat 3 is ring structure, and center is provided with the second through hole, and the inwall of outer rim and plunger 2 is fixed and is tightly connected, be positioned at and be provided with the second valve ball 64, second valve ball 64 above the second valve seat 3 and form shutoff for coordinating with the second through hole in plunger 2.
When the bottom of pump barrel 1 is insinuated in pumping crude oil, treat that pumping crude oil pours in the pump barrel 1 above the first valve seat 5 by the first through hole, this seasonal plunger 2 slide downward, the bottom of plunger 2 is inserted into and treats to need in pumping crude oil in pump barrel 1, treat that pumping crude oil is washed the second valve ball 64 open and pours in the top of the second valve seat 3; Now upwards lift plunger 2, second valve ball 64 and form shutoff with the second through hole under the effect of the pressure, meanwhile, in the pump barrel 1 of the below of the second valve seat 3, form negative pressure, make to treat that pumping crude oil continues to pour in pump barrel 1.Lift is stopped when plunger 2 rises to setting height, make plunger 2 slide downward subsequently, treat that pumping crude oil loses the effect of negative pressure and moves downward in pump barrel 1, first valve ball is shutoff first through hole under the effect of the pressure, thus let out under preventing treating pumping crude oil, plunger 2 continues downwards deeply, until the degree of depth slipping down to setting upwards lifts again, so repeatedly, will treat that pumping crude oil continues upwards pumping.
Wherein, be positioned at above the first valve ball and be also provided with the first cyclone structure 7 in pump barrel 1, first eddy flow knot is arranged near the first through hole, until pumping crude oil when by the first through hole, under the effect of the first cyclone structure 7, make near this place treat pumping crude oil formed eddy current, thus crude oil is played to the effect of stirring, can prevent the coal dust in crude oil or sand sedimentation from burying valve ball valve seat like this, ensure that driving oil well pump when taking out can normally work next time.
Same, be positioned at above the second valve ball 64 and be provided with the second cyclone structure 8 in plunger 2, second cyclone structure 8 for make by the second through hole treat pumping crude oil formed eddy current, make coal dust or sand suspension in liquid stream, and carried away by liquid stream, prevent the coal dust in crude oil or sand sedimentation from burying valve ball valve seat with this.
Preferably, the top side of the first through hole and the second through hole is spherical shape structure, the form structure of more fit thus the first valve ball and the second valve ball 64, contributes to the location of the second valve ball 64 and the second valve ball 64, and sealing effect when can promote shutoff.
First cyclone structure 7 and the second cyclone structure 8 include inner ring and multiple flabellum, multiple flabellum distribution is connected on the outer wall of inner ring, inner ring is connected to the central position of pump barrel 1 or plunger 2 by multiple flabellum, and the diameter of inner ring is less than the diameter of the first valve ball and the second valve ball 64.For what make to pass through, multiple flabellum treats that pumping crude oil forms eddy current, inner ring is not only for fixing multiple blade, also can play spacing effect to the first valve ball or the second valve ball 64, prevent the first valve ball and the second valve ball 64 and the first valve seat 5 and the second valve seat 3 from keeping less distance, with the timely shutoff when liquid flow path direction changes.
In addition, because the first cyclone structure 7 and the second cyclone structure 8 are separately positioned on the top of the first valve seat 5 and the second valve seat 3, when liquid stream moves downward, now the first valve ball and the second valve ball 64 are about to be in sealed condition, and now can form whirlpool respectively in the below of the first cyclone structure 7 and the second cyclone structure 8, first valve ball, the second valve ball 64, first through hole and the second through hole are just in this whirlpool, thus can effectively prevent the coal dust in crude oil or sand sedimentation from burying valve ball valve seat.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
