Abstract
The utility model discloses an adjustable oil nozzle sleeve, comprising a oil nozzle sleeve body internally provided with an upper valve plug, wherein an oil flow channel is horizontally arranged in the lower part of the oil nozzle sleeve body, the upper valve plug is driven to lift by a valve rod arranged in the oil nozzle sleeve body so as to adjust the size of the oil flow channel, the cross section of the oil flow channel is in a quadrilateral shape, a vertical plane, in which an upper corner ridge and a lower corner ridge of the oil flow channel are located, and a valve rod axis are arranged in a coplanar way, the bottom of the upper valve plug is provided with an inverted V-shaped groove, the size of the V-shaped groove is matched with the size of the cross section of the upper half part of the oil flow channel. The utility model has the characteristics of simple structure and convenient use and can realize that the oil flow channel can be shifted for the production oil well, without shutting down.
Description
Technical field
The utility model belongs to oil field down-hole extraction flow quantity control appliance, relates to a kind of adjustable oil nozzle cover.
Background technology
In the oil exploitation process; down-hole extraction flow quantity control appliance generally all will be used the oil nozzle cover; existing oil nozzle cover can not carry out real-time conversion adjustment to oil flow channel; conversion oil flow channel if desired; need carry out shutdown operation to production well; use very inconveniently, the raising of production efficiency is had very big influence.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable oil nozzle cover, and it is simple in structure, can adjust the size of conversion oil flow channel in real time, and is easy to operate, helps to reduce oil well downtime, improves oil recovery production efficiency.
The purpose of this utility model is achieved in that a kind of adjustable oil nozzle cover, the oil nozzle cover body of upper valve core is housed in comprising, be horizontally disposed with oil flow channel in the bottom of oil nozzle cover body, upper valve core overlaps the size that intrinsic valve rod drives lifting and regulates oil flow channel by being installed in oil nozzle, said oil flow channel cross section is quadrangle, on the oil flow channel, the perpendicular and the valve rod axis co-planar arrangement at crest line place, following two bights, the upper valve core bottom surface has an inverted V font groove, and the cross section size of the size of V font groove and the said oil flow channel first half is complementary.
By the upper cap that is being threaded, on the end face outer peripheral edges of upper cap the angle scale is being set in the upper end of oil nozzle cover body, is being horizontally disposed with rotation hand wheel on the top of valve rod.
When the utility model uses, it is connected with the well head pipeline, when needs are adjusted the oil nozzle endoporus, rotates handwheel, regulate the high and low position of upper valve core, can regulate the size of oil flow channel by welding.This apparatus structure is simple, can adjust the size of conversion oil flow channel in real time, and is easy to operate, helps to reduce oil well downtime, improves oil recovery production efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is a side-looking cross-sectional view of the present utility model.
The specific embodiment
A kind of adjustable oil nozzle cover, as shown in Figure 1 and Figure 2, the oil nozzle cover body 3 of upper valve core 5 is housed in comprising, be horizontally disposed with oil flow channel 4 in the bottom of oil nozzle cover body 3, the size that upper valve core 5 is driven lifting and regulated oil flow channel 4 by the valve rod that is installed in the oil nozzle cover body 3, said oil flow channel 4 cross sections are quadrangle, and tetragonal width can be 1-60mm.The perpendicular and the valve rod axis co-planar arrangement at the crest line place, upper and lower two bights of oil flow channel 4, upper valve core 5 bottom surfaces have an inverted V font groove 6, and the cross section size of the size of V font groove 6 and said oil flow channel 4 first halves is complementary.
Said oil flow channel 4 cross sections are square or rhombus.
By the upper cap 2 that is being threaded, on the end face outer peripheral edges of upper cap 2 the angle scale is being set in the upper end of oil nozzle cover body 3, is being horizontally disposed with rotation hand wheel 1 on the top of valve rod.When needs are adjusted oil nozzle endoporus oil flow channel 4 big or small, rotate handwheel 1, with respect to the angle that angle index rotated, promptly the size of decidable oil nozzle endoporus oil flow channel is easy to use by the pointer on the handwheel 1.
