Description
Technical field
The present invention relates to the connection of composite steel tube, it is that one kind is applied to two composite steel tubes are quickly coupled together
Coupling.
Technical background
At present, in laying, the connection using composite steel tube and composite steel tube all adopts existing pressure piping
Butt welding connects and ring flange connects, but it is to connect when ring flange connects that both connects the deficiency existing
Bolt is many, and pretightning force is uneven, easily causes sealing member deformation, evaporating, emitting, dripping or leaking of liquid or gas phenomenon and occurs, boil on the nape opposite the mouth is welded
When connecing, composite steel tube and the junction of composite steel tube, because being affected by temperature, geological conditions, are welded to connect and reach not
To the requirement of quality, anticorrosive coat is more easily damaged, operator be subject in pipe laying welding operation space,
The restriction of reason position, is difficult to pipe end to align, brings the difficulty of operation to welding, welding quality obtains not
To guarantee, welding rear port needs to polish, and the weld bond of composite steel tube junction is easy to crack, and anticorrosive coat cannot
Ensure, so shorten the service life of tubing, and take a lot of work, time-consuming, laborious.
Content of the invention
In order to overcome above-mentioned deficiency, the invention aims to provide a kind of for tubing high temperature resistant,
High pressure resistant, the corrosion resistant quick coupling of chuck formula with groove, coupling one end be provided with recessed
Sealing ring is installed on the trapezoidal disk composite steel tube of shape groove, the trapezoidal disk composite steel tube of the convex that the other end is provided with is inserted
Enter in Baltimore groove, two chucks are arranged on two trapezoidal flange excircles, tighten bolt and complete to connect, feature is
Repair mouth without polishing, anticorrosive coat is not destroyed, pipe fitting arbitrarily rotate and need not deliberately centring, sealing member
Uniform force, clamping force is big, and good airproof performance is few using bolt quantity, easy for installation, quick, can improve
Work efficiency, that is, save time, laborsaving, saving of labor, is less prone to the generation of the phenomenons such as weld bond cracking again.Not only carry
The high mutual compression intensity of two joint faces and sealing property, have simplified operation sequence again.
The technical solution adopted for the present invention to solve the technical problems is that this joint is combined by two trapezoidal flanges
Steel pipe A, B, two chucks, sealing ring etc. forms, and is provided with recessed together in trapezoidal flange composite steel tube A front end face
Shape sealing ring groove, is provided with sealing ring in female seat ring recess, and trapezoidal flange composite steel tube B front end face is provided with
The convex matching with female seat ring recess together, in trapezoidal flange composite steel tube A and trapezoidal flange clad steel
It is arranged with two chucks, the ear mount of two chucks is provided with locking screw keyhole on pipe B is cylindrical, during use,
First sealing ring is contained in female seat ring recess, then by the front end convex of trapezoidal flange composite steel tube B against
On sealing ring end face, two chucks are arranged on trapezoidal flange excircle, clamping screw passes through bolt hole to twist
Enter in locking nut.
The invention has the beneficial effects as follows, due to employing above-mentioned design, after the completion of composite steel tube connects,
Repair mouth without polishing, connect without ring flange, anticorrosive coat is not destroyed, that is, easy for installation, quick, improve
Work efficiency, saves time, laborsaving, saving of labor again, extends the service life of tubing, this joint is applied to various
The use of environment, without special technique during operation, operating personnel only needs wrench operated, and pipe fitting arbitrarily revolves
Then need not deliberately centring, installation rate is fast, decreases labor intensity, is connection composite steel tube at present
Comparatively ideal joint.
Brief description
The present invention is further described with reference to the accompanying drawings and examples.
Accompanying drawing 1 is the schematic diagram of the present invention.
Accompanying drawing 2 is the sectional view of chuck of the present invention.
In figure 1, joint, 2, trapezoidal flange composite steel tube B, 3, convex, 4, female seat ring recess, 5,
Trapezoidal flange, 6, trapezoidal flange composite steel tube A, 7, chuck, 8, locking screw keyhole, 9, ear mount, 10,
Sealing ring.
Specific embodiment
Joint 1 by trapezoidal flange composite steel tube B2, convex 3, female seat ring recess 4, trapezoidal flange 5,
Trapezoidal flange composite steel tube A6, chuck 7, sealing ring 10 grade forms, trapezoidal flange composite steel tube B2,
Trapezoidal flange 9 in trapezoidal flange composite steel tube A6 is made with 45# steel forging, and trapezoidal is turnning and milling molding,
The groove of female seat ring recess 3, convex 3 are lathe process, and chuck 7 is to be made with 45# steel forging and become through turnning and milling
Type, chuck 7 is drilled with locking screw keyhole 8, in trapezoidal flange composite steel tube A6 fovea superior shape sealing ring groove 4
Inside put into sealing ring 10, the thickness of sealing ring 10, diameter can be according to the diameter dimension of composite steel tube, pipeline pressures
Power determines the size of sealing ring 10, and the convex 3 on trapezoidal flange composite steel tube B2 is inserted female seat circle
In groove 4 and on the end face of sealing ring 10, then chuck 7 is installed on trapezoidal flange 5, then by spiral shell
Bolt is screwed in locking nut through locking screw keyhole 8, after the completion of joint connects, you can use.
