Description
Technical field
The utility model relates to a kind of sleeve pipe connection device, particularly a kind of COMPRESSIONTYPE cover pipe connection.
Background technology
The box cupling of petroleum casing pipe is the one in petroleum pipeline fixture, is widely used in field of petroleum exploitation; The existing box cupling for petroleum casing pipe comprises wellhead flange, reinforces pipe nipple, slips, inner sleeve, bleeder pipe, upper flange and lower flange, inner sleeve connects wellhead flange, be fixedly connected with by reinforcing pipe nipple between wellhead flange with upper flange, upper flange and lower flange link together, fixed by slips between lower flange and inner sleeve, inner sleeve between upper flange and wellhead flange is provided with bleeder pipe, the outside fixed jacket pipe of inner sleeve, and upper flange and lower flange junction are provided with sealing ring; This box cupling for petroleum casing pipe finds in using, and due to the winter in cold, causes overall box cupling to use.In oil drilling oil recovery process, wellhead casing pipe linkage is a kind of parts of splicing sleeve and various wellhead assembly, in order to bear the various stressed of protective casing and production string, the annular space between Sealing Technology sleeve pipe and production string, installs preventer.
Chinese patent literature publication number: CN 202731821 U, patent name is " thermal production well wellhead casing pipe linkage ", comprise fixed cover, sleeve pipe suspension joint, black box, casing joint, plug, housing, black box is arranged in housing, black box lower seat is on enclosure interior shoulder, sleeve pipe suspension joint seat is on black box, connecting thread is arranged at sleeve pipe suspension joint top, sleeve pipe suspension joint bottom is connected with casing joint top, production string screw thread is arranged at casing joint bottom, lower housing portion has protective casing screw, housing there is side direction import, plug is arranged in side direction import, the bottom of fixed cover is fixed in housing upper, black box is pushed down in the lower surface of fixed cover, there is steel ring slot the upper surface of housing, this protective casing and production string are carry out completion by welding doughnut-shaped steel plate at well head place, because the length wanting protective casing and production string to expand with heat and contract with cold during thermal recovery steam injection is different, therefore, when above-mentioned completion mode is not suitable for heavy oil wells heat extraction by steam injection, also need at the scene to cut open doughnut-shaped steel plate, bring very large potential safety hazard, when drilling well two is simultaneously opened, effectively preventer can not be installed, two occur that emergency episode not easily processes when opening, and add the danger of drilling well.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and provide a kind of COMPRESSIONTYPE to overlap pipe connection, easy to connect between parts, reliable, firm, good seal performance, bearing capacity is large.
Its technical scheme is: comprise joint, sleeve pipe, sleeve pipe jointing, it is characterized in that: the inside, connector place of described joint is provided with inner conical mouth, the outside, connector place of joint is provided with nipple, sleeve pipe is connected with the inner conical mouth of joint, described sleeve pipe is connected by nut with the outside of joint, and the inner conical mouth of described joint and the junction of sleeve pipe are provided with cutting ferrule sealing ring, and the junction of nut and joint is provided with retaining ring; Above-mentioned retaining ring is trapezium structure, and the inside of retaining ring is provided with screw thread tapered sleeve, and the two ends, left and right of described retaining ring are circular arc chamfering structure.
Above-mentioned thread conical is set on the both sides up and down of retaining ring inner chamber.
The beneficial effects of the utility model are: the installation and removal facilitating each component, improve efficiency of assembling, easy to connect between each parts, reliable, firm, good seal performance, and bearing capacity is large, can easily, carry out connection and the exchange of union rapidly.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of retaining ring;
In upper figure: joint 1, sleeve pipe 2, nut 3, cutting ferrule sealing ring 4, retaining ring 5, inner conical mouth 1.1, nipple 1.2, screw thread tapered sleeve 5.1.
Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises joint 1, sleeve pipe 2, sleeve pipe 2 jointing 1, the inside, connector place of described joint 1 is provided with inner conical mouth 1.1, the outside, connector place of joint 1 is provided with nipple 1.2, sleeve pipe 2 is connected with the inner conical mouth 1.1 of joint 1, described sleeve pipe 2 is connected by nut 3 with the outside of joint 1, and the inner conical mouth 1.1 of described joint 1 is provided with cutting ferrule sealing ring 4 with the junction of sleeve pipe 2, and nut 3 is provided with retaining ring 5 with the junction of joint 1; Retaining ring 5 is wherein trapezium structure, and the inside of retaining ring 5 is provided with screw thread tapered sleeve 5.1, and the two ends, left and right of described retaining ring 5 are circular arc chamfering structure.Above-mentioned screw thread tapered sleeve 5.1 is arranged on the both sides up and down of retaining ring 5 inner chamber, plays certain supporting role.
Under sleeve pipe adopts ring pressure type connected mode, realize being tightly connected by retaining ring, cause the sealing ring when retaining ring ring is pressed to be forced to inside contraction during connection, and force sealing ring that all gap fillings is full, pressure is higher, and its sealing effectiveness is better; In compacting, the stable section of interface is together with locking locking after the sleeve pipe concave deformation inserted; Make encapsulant in cavity internal strain flowing to exerting pressure of seal section, fully to fill the gap between sleeve pipe and joint, thus realize tubing and pipe fitting effectively seals.
