Abstract
The utility model relates to a device for recovering petroleum. The utility model is characterized in that a suspension joint and a center pipe are connected by a safety pin; a valve seat is arranged in the joint; a valve ball, a valve cover, a valve ball supporting rod and a spring are arranged below the valve seat; the upper end of an outer cylinder is connected with the joint, and the lower end is connected with a regulating head. The utility model can protect a steel cable from tensile failure and can automatically discharge loads to guarantee the safety of an oil well and a lifting device; the utility model is suitable for a low-producing oil well to produce crude oil.
Description
The utility model belongs to the machine instruction statement mining oil field, relates to a kind of extracting device of oil.
At present the swab that uses at the scene mainly is made of hanging joint, central tube, the ball-and-seat etc. that is enclosed within glue tube base and the packing element on the central tube and is installed in the central tube bottom.This swab, its ball-and-seat pressure release load value can not be regulated, and can only can not adapt in the various at the scene complex hole condition and use by the design load pressure release; Too narrow and small because of its ball-and-seat pressure release passage, normally pressure release usually causes to promote the load overload, causes the wire rope break-off accident sometimes; Because this swab do not have safe escape mechanism, if swab last carry in the process load excessive, when meeting card, wire rope may be broken, cause the accident.
The purpose of this utility model is to design a kind of disconnected safely taking off of both can having realized, also can regulate level pressure and let out the safe escape formula swab that carries.
The utility model is to realize like this, a kind of safe escape formula swab, hanging joint connects mutually with central tube, and constitute by the ball-and-seat that is enclosed within glue tube base and the packing element on the central tube and is installed in the central tube bottom, its special character is, is connect by safety pin between hanging joint and the central tube.
In above-mentioned technical solution, its special character also is, by screw thread joint, urceolus, adjusting head is installed successively in the central tube bottom, and valve seat is housed in urceolus, valve ball, valve ball pressure pin, spring, spring base are housed below valve seat successively, and the valve ball cover is installed in the joint by screw thread.
In above-mentioned technical solution, its special character also is, by screw thread guard shield is installed in the hanging joint outside.
The utility model has the advantages that (1) promotes traffic overload as occurring in drag for the oily journey of crossing with this swab, when acquiring a certain degree, safety pin can break and take off, and has protected wire rope; (2) in lifting process, if promote load (lifting liquid measure) overload, can let out automatically and carry, guarantee oil well and lifting means safety; (3) as required, can regulate the lifting load easily.
Accompanying drawing is the structural representation that partly cuts open of the present utility model.
Be further described (embodiment) below in conjunction with accompanying drawing:
The lower end of hanging joint 1 is enclosed within the upper end of central tube 4, their pin hole is aligned, can design 3-4 pin hole as required, safety pin 3 is installed in pin hole, during design,, make the load of breaking of pin break load less than wire rope according to the material and the diameter of pin.Has through hole on the central tube 4.By screw thread guard shield 2 is contained on the hanging joint 1, deviates to prevent safety pin 3.Glue tube base 5, packing element 6, glue tube base 7 are sleeved on the central tube 4 successively the lower end of pipe 4 during joint 8 is installed in by screw thread.Valve seat 9 is installed in the joint 8, valve ball 10, valve ball pressure pin 12 are contained in valve seat 9 belows successively, valve ball cover 11 is installed in the joint 8 by screw thread, urceolus 15 is installed in the lower end of joint 8 by screw thread, has through hole on the urceolus, successively spring base 13, spring 14, spring base 16 are contained in the urceolus 15, constitute ball-and-seat.Be installed in the lower end of urceolus 15 with regulating 17 by screw thread.As required, a precession or screw out to regulate 17 can be regulated the lifting load of swab, perhaps changes different flexible springs, also can adjust it and promote load.
This swab is applicable to low yield oil well production crude oil.In taking out the process of dragging for, if for some reason swab is stuck in the pit shaft, on carry when motionless, the strength of carrying on increasing again, because of the safety pin 3 of design always break load than wire rope to break load low, safety pin 3 is promptly broken, and wire rope can propose pit shaft with the hanging joint 1 of its connection, and then salvages.When taking out when dragging for, if,, can bleed off some liquid automatically, reduce to promote load by valve ball 10, valve ball pressure pin 12 compression springs 14 because of promoting the liquid measure overload, guarantee the safety of oil well and lifting means, accomplish safety in production.
Claims (3)
1. safe escape formula swab, hanging joint (1) connects mutually with central tube (4), and, it is characterized in that: connect by safety pin (3) between hanging joint (1) and the central tube (4) by the ball-and-seat formation that is enclosed within glue tube base (5,7) and the packing element (6) on the central tube (4) and is installed in central tube (4) bottom.
2. safe escape formula swab according to claim 1, it is characterized in that: joint (8), urceolus (15) are installed successively, regulate head (17) by screw thread in central tube (4) bottom, valve seat (9) is housed in urceolus (15), valve ball (10), valve ball pressure pin (12), spring base (13), spring (14), spring base (16) are housed below valve seat successively, and valve ball cover (11) is installed in the joint (8) by screw thread.
