Description
Technical field
The utility model belongs to underground operation tool technical field of tools more particularly to a kind of filter net type variable diameter oil pipe is short
Section.
Background technique
Currently, oilfield downhole operation construction site generally uses 27/8 inch to thicken the oil for thickening two kinds of specifications with 23/8 inch
Pipe, it is corresponding just to need two kinds of lifting subs, two kinds of pipe elevators.Problem be 27/8 the inch heavy wall tubing elevator moon frequency of use exist
3000 pieces times or more, and 23/8 the inch heavy wall tubing elevator moon frequency of use at 10 times hereinafter, being matched with so low frequency of use
A standby safe handling time limit has the elevator of strict demand obviously uneconomical, in addition, existing promotion, which is shorted, does not have filtering function
Energy.To solve the above-mentioned problems, the utility model patent of Patent No. CN201520715591.0 discloses a kind of filtering change
Diameter tubing nipple device.However, the filter structure in the device is complicated, and clear up arduously, needs to improve.
Utility model content
The utility model provides a kind of filter net type variable diameter tubing nipple, to solve the problems mentioned in the above background technology.
The technical problem solved by the utility model is implemented by the following technical solutions: the utility model provides one kind
Filter net type variable diameter tubing nipple, including top connection, locking member, lower contact and strainer, top connection, locking member and lower contact by up to
Under pass sequentially through threaded connection, the upper end of the strainer is provided with flange, and flange is clipped in the upper of the top connection and locking member
Between end, so that strainer to be fixed on to the inside of the filter net type variable diameter tubing nipple, clamping is provided on the locking member
Section A and clamping section B, the lower end of the strainer are provided with centralizer body, are against on the inside of the lower contact on the outside of centralizer body, filter
The lower end of net is inserted in the circular hole in centralizer body center, and the channel passed through for liquid is provided on centralizer body.
The strainer is the tubular structure of open at both ends, and the lower end of strainer is provided with the plug for blocking strainer, is blocked up
Head is fixedly connected on strainer.The plug is made of polythene material.Cone is provided on the upside of the plug.
The utility model has the following beneficial effects: the utility model structure is simple, design is reasonable, especially, on locking member
Provided with upper and lower two clampings section, when normal operation, elevator is stuck on clamping section A, convenient for operation, needs to carry out strainer clear
When reason, elevator is stuck on clamping section B, at this point, top connection can be removed by vising top connection and locking member respectively with pipe wrench, after
And take out strainer, realize the cleaning to strainer, therefore, the utility model also has the advantages that cleaning is convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1- centralizer body, 2- lower contact, 3- strainer, 4- cone, 5- locking member, 6- clamping section B, 7- clamping section A,
8- top connection, 9- plug.
Specific embodiment
The utility model is described further below in conjunction with attached drawing:
The present embodiment includes top connection 8, locking member 5, lower contact 2 and strainer 3, top connection 8, locking member 5 and lower contact 2 by
Threaded connection is passed sequentially through under.
The upper end of the strainer 3 is provided with flange, and flange is clipped between the upper end of the top connection 8 and locking member 5, from
And strainer 3 is fixed on to the inside of the filter net type variable diameter tubing nipple.Based on this structure, when clearing up strainer 3, only
Top connection need to be removed strainer 3 can be taken out and cleared up.
It is provided with clamping section A7 and clamping section B6 on the locking member 5, when normal operation, elevator is stuck in clamping section A7
On, convenient for operation, when needing to clear up strainer 3, elevator is stuck on clamping section B6, at this point, on being vised respectively with pipe wrench
Connector 8 and locking member 5 can remove top connection 8, then take out strainer 3, realize the cleaning to strainer 3, and therefore, this is practical
It is novel also to have the advantages that cleaning is convenient.
The lower end of the strainer 3 is provided with centralizer body 1, can help in axially and radially both direction strainer 3,
To enhance the ability that strainer 3 resists water impact.The outside of centralizer body 1 is against on the inside of the lower contact 2, under strainer 3
End is inserted in the circular hole in 1 center of centralizer body.
The channel passed through for liquid is provided on centralizer body 1, i.e. liquid can pass through righting from top to bottom or from the bottom to top
Body 1.
The strainer 3 is the tubular structure of open at both ends, and the lower end of strainer 3 is provided with the plug for blocking strainer 3
9, plug 9 is fixedly connected on strainer 3, and when clearing up strainer 3, plug 9 is removed can be convenient for the removing of dirt in strainer 3.
The plug 9 is made of polythene material, compared with metal material, can be effectively improved using polythene material stifled
First 9 erosion resistibility, to improve the service life of plug 9.
The upside of the plug 9 is provided with cone 4, and cone 4 can carry out water conservancy diversion to the liquid flowed into from top, from
And liquid stream agitation is reduced, to reach reduction liquid flowing resistance, reduce the effect washed away of the liquid stream to each part.
