Abstract

The utility model discloses a metal hard seal pipe joint, which comprises a hollow joint body, a nut and a hollow stainless steel sleeve the longitudinal section of which is in a T shape. The end part of the joint body is a straightway bearing spigot, a spherical cap cambered water stop flange is arranged around the inner wall of the bearing spigot at the position close to the middle part of the joint body inside the bearing spigot, and the outer wall of the bearing spigot is provided with screw threads matched and screwed together with the nut. One end with a T-shaped outer edge of the stainless steel sleeve is sleeved into the nut, the surface of the T-shaped outer edge tightly leans against the inner edge of the nut, and the other end of the stainless steel sleeve is inserted into the bearing spigot of the joint body. The structure is widely used in the connection of metal pipes such as stainless steel pipes, copper pipes, aluminum pipes and the like. Because of the hard seal connection of the homogenous material of the pipe and the joint, no rubber seal aging or cracking exists, and the pipeline is safe and reliable. The connection between the pipe and the joint is tightened by the nut, and the pipeline can be successfully reformed after the nut is unscrewed. No special installation tool is needed, no special technical requirement or operational skill is required to the installation workers, and the installation of the joint is easy and fast.

Description

The metal hard-sealing pipe joint
Technical field
The utility model relates to metal pipe and the joint technology that is tightly connected firmly, particularly a kind of metal hard-sealing pipe joint.
Background technique
Existing metal pipe Placement, be generally multiple Placements such as compression type, clamp-press type, ring pressure type, FERRULETYPE, groove clamping hoop type, although these Placements and special installation tool thereof are had nothing in common with each other, but a common feature is arranged all, be exactly all to need by sealing material, fill tubing and gaps between pipe fittings as elaxtic seals such as raw meal belt, anaerobic adhesive, rubber ring, tetrafluoroethylene pads, reach the effect of sealing sealing, and these sealing materials tend to make the sealing seal failure cause leaking because of light, heat ageing; Particularly, expressly provide in the fuel gas pipeline job specfication, must not use sealing material such as rubber ring to be used for the fuel gas pipeline system, tubing must be welding with being connected of pipe fitting or be tightly connected firmly.These prove absolutely that all the quality quality of sealing material and the selection of sealing means are the keys that concerns the pipe-line system safe operation, have much room for improvement.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of metal hard-sealing pipe joint is provided, and can reach the purpose that pipeline is safe and reliable, easy construction quick, installation cost reduces.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of metal hard-sealing pipe joint is provided, comprises the joint body and the nut of hollow, it also comprises the stainless steel sleeve of hollow, and its longitudinal section is a T shape; The end of joint body is straight-through joint socket, and joint socket is provided with a spherical crown arc sealing flange near the joint body medium position around its inwall toward interior, and the outer wall of joint socket is provided with screw thread, cooperates with nut to twist to connect; One end of stainless steel sleeve band T shape outer is inserted in the nut, and surface, T shape outer is tight against edge in the nut, and the other end of stainless steel sleeve inserts in the joint socket of joint body.
Adopt the structure of above-mentioned metal hard-sealing pipe joint, be widely used in the connection of metal tubes such as Stainless Steel Tube, copper pipe, aluminum pipe, has the useful technique effect of following many-side: owing to be that homogeneous material is tightly connected firmly between tubing and the joint, no rubber seal is aging, the sorrow of be full of cracks, and pipeline is safe and reliable; Tubing is fastening by nut with being connected of joint, when needs carry out pipeline transformation, but turns on just smooth implementation of nut; Do not need special special installation tool, the installer is not had special technical requirements and operative skill, only need conventional instruments such as adjustable spanner to get final product easy manipulation, install convenient and swift.
Description of drawings
Below in conjunction with the drawings and specific embodiments structure of the present utility model and advantage are further described.
Fig. 1 be described model utility B-B to sectional view;
Fig. 2 be described model utility B-B to sectional exploded view.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of metal hard-sealing pipe joint is provided, described pipe joint is according to the pipeline laying needs, straight-through, elbow, two logical, four-ways can be arranged, and the inside and outside tooth pipe joint of tapered thread pipeline of the usefulness that is connected with plumbing, the straight coupling that only is communicated with tubing with two ends is that example describes below.It comprises the joint body 1 and the nut 2 of hollow, and joint body 1 is a stainless steel material, also can be other rigid metallic material.It also comprises the stainless steel sleeve 3 of hollow, and its longitudinal section is a T shape.The end of joint body 1 is straight-through joint socket 4, and joint socket 4 is provided with a spherical crown arc sealing flange 5 near joint body 1 medium position around its inwall toward interior, and the outer wall of joint socket 4 is provided with screw thread, cooperates with nut 2 to twist to connect; One end of stainless steel sleeve 3 band T shape outers is inserted in the nut 2, and surface, T shape outer is tight against edges in the nut 2, and the other end of stainless steel sleeve 3 inserts in the joint socket 4 of joint body 1.When actual installation practice, length intercepting tubing 6 on demand, foreign material such as the burr of removal section end, metal fragment, tubing 6 is passed nut 2, stainless steel sleeve 3 successively, the joint socket 4 that inserts joint body 1 at last is interior to the bottom, firmly nut 2 rotations is tightened in opposite directions simultaneously with two spanners then.Stainless steel sleeve 3 is positioned at the upper end position of joint socket 4 near spherical crown arc sealing flange 5 originally, progressively screw under the thrust that is produced at nut 2, stainless steel sleeve 3 moves axially along tubing 6, and be inserted between spherical crown arc sealing flange 5 and the tubing 6, until the lower end position of spherical crown arc sealing flange 5; Make a concerted effort down at the resistance that is inserted into power and spherical crown arc sealing flange 5, stainless steel sleeve 3 is radially distortion in tubing 6, has formed between spherical crown arc sealing flange 5, stainless steel sleeve 3 and tubing 6 threes with the closely cooperating of radian, and has reached the effect of sealing sealing; And the bottom, T shape outer of stainless steel sleeve 3 also pushes against on the port surface of joint body 1 this moment, has further strengthened the good result of sealing sealing; Simultaneously, the circumferential groove that spherical crown arc sealing flange 5, stainless steel sleeve 3 and tubing 6 force actions form has down also played the effect of tension pull out force.
The foregoing description is a preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to protection category of the present utility model.
