Technical Field
The invention relates to the technical field of oil pipe connection, in particular to a ball type oil pipe quick connector.
Background
Tubing is the pipe that transports crude oil and natural gas from the hydrocarbon reservoir to the surface after drilling is complete and is used to withstand the pressures generated during production.
When the oil pipe is laid on the original ground and connected, the existing process is to connect the oil pipe by using a coupling, the construction process that the coupling is connected with the oil pipe is complex in the construction process, the oil pipe and the coupling thread can be screwed up only by rotating the oil pipe for a plurality of circles, the time and the labor are wasted, and the working efficiency is greatly reduced.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the ball type oil pipe quick joint, which makes up the defects in the prior art.
In order to achieve the purpose, the invention provides the following technical scheme: ball formula oil pipe quick-operation joint connects including a left side and connects on the right side, the top and the bottom that connect on a left side all are equipped with the lock sleeve, the inner chamber of lock sleeve is equipped with the spring, the bottom and the top that connect the inner chamber on a left side all bond and have the sealing washer, the bottom that connects the inner chamber on a left side and one side that the top just is located the sealing washer are equipped with the ball body.
Preferably, the shape of ball body is the ball-type, and the specification of two ball bodies is unanimous, through the setting of ball body, conveniently takes out right joint when demolising, has improved the efficiency of dismouting greatly.
Preferably, the working pressure of the inner cavities of the left joint and the right joint is the same, and the pressure is 0-35 MPa, 70 MPa and 105MPa.
Preferably, the sealing ring is bonded to the inner cavity of the left joint through an adhesive, the sealing ring is made of rubber, and the phenomenon that crude oil overflows in the output process is avoided through the arrangement of the sealing ring, so that the sealing effect is achieved.
Preferably, the total length of the left joint and the right joint is 300mm, and the height of the left joint and the right joint is 145mm.
Preferably, the latus rectum that connects on a left side is the same with the right side, and the latus rectum is cun tooth, the hole has been seted up to the inner chamber that connects on a left side.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention firstly screws a left joint on an oil pipe, then screws a right joint on another oil pipe, after connection is completed, the user coats lubricating grease on the contact surface of the two joints and pulls a locking sleeve leftwards, movement is stopped when the locking sleeve moves to a specified position, then the user aligns the right joint with an inner hole of the left joint and inserts the right joint to the specified position to stop movement (note that the left joint and the right joint are ensured to be on a horizontal line and not to incline), meanwhile, the user loosens the locking sleeve, the locking sleeve enables a ball body to reset under the action of a spring, the two joints are connected together by the ball body, connection is completed at the moment, and finally, if the left joint and the right joint need to be separated, the user pushes the locking sleeve leftwards on the left joint and pulls the right joint rightwards, and the ball body pops out due to a gap at the end part of the locking sleeve, the right joint can be smoothly withdrawn, and the left joint and the right joint can be disassembled.
2. According to the invention, through the arrangement of the ball body, the right joint is convenient to take out during dismounting, so that the dismounting efficiency is greatly improved;
through the setting of sealing washer, the phenomenon that crude oil spills over appears in the in-process of output is avoided, reaches sealed effect.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a cross-sectional view of a left joint and a right joint of the present invention;
FIG. 3 is an enlarged view of the invention at A.
In the figure: 1. a left joint; 2. a right connector; 3. a spring; 4. a seal ring; 5. a ball bearing; 6. and a locking sleeve.
Detailed Description
The invention is further described with reference to the following figures and embodiments.
Please refer to fig. 1, fig. 2 and fig. 3 in combination, wherein fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a cross-sectional view of a left joint and a right joint of the present invention; FIG. 3 is an enlarged view of the invention at A.
Example 1
Ball formula oil pipe quick-operation joint connects 2 including left side joint 1 and right side, and the top and the bottom that the left side connects 1 all are equipped with lock sleeve 6, and the inner chamber of lock sleeve 6 is equipped with spring 3, and the bottom and the top of the 1 inner chamber of left side joint all bond and have sealing washer 4, and the bottom and the top of the 1 inner chamber of left side joint just lie in one side of sealing washer 4 and be equipped with ball body 5.
The user twists on oil pipe with left side joint 1, twist another oil pipe with right side joint 2 again, connect the back of accomplishing, the user scribbles lubricating grease with two joint contact surfaces and stimulates lock sleeve 6 left, it is the motion stop to move to appointed position, then the user aligns the hole of left side joint 1 with right side joint 2, insert appointed position motion stop, the user loosens lock sleeve 6 simultaneously, lock sleeve 6 makes ball body 5 reset under spring 3's effect, utilize ball body 5 to link together two joints.
