Description
Technical field
The present invention relates to a kind of pressurized gas pipeline joint, particularly relate to the rapid pipe joint of a kind of pressurized gas pipeline.
Background technique
Need the extension carrying out pipeline somewhere to connect for the pipeline of transporting compressed gas body in the market and transformation time, have various ways.Be adopt traditional cutting welding manner to carry out extension to connect or transformation at first, but this mode is outmoded, not only the large difficulty of labor intensity is high wastes time and energy, and needs stopping production to be undertaken by professional and technical personnel, had afterwards and connected pressurized gas pipeline with joint, but the pipe coupling used in the market is not specially for the joint of pressurized gas pipeline mostly, in use often occurs the Leakage Gas phenomenon that pressure loss is comparatively large, sealing does not cause by force in the joint of pipeline, in addition current existing pipe coupling in use, and the stopper in joint is in embedding death situation state usually, and it is irremovable at axial direction, and the frictional force in pipeline insertion and withdrawal process between this stopper and compressed pipe can make insertion pull action very difficult, or by a pressing member by or fixing maybe the bayonet socket of stopper of movement can to prop up and oppress the turnover that bayonet socket opens to facilitate compressed pipe, then utilize in pipeline during locking and pass into liquid and make the axial expansion push card stop member of seal ring to engage pipeline, but this kind of mode is not also suitable for gas pipeline, though and very handy time pipeline in actual mechanical process inserts joint, but the shell fragment on stopper is still in when pipeline does not lead to liquid the state comparatively expanded, make it not fastening to the locking of pipeline, potential safety hazard is existed to the situation after liquid logical in pipeline, in this external pipeline withdrawal process, although by pressing member by pressing off bayonet socket, but due to liquid heats seal ring, therefore in actual dial-out process, stopper bayonet socket still can be stuck in pipeline outer wall, pipeline is transferred to very difficult.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding the rapid pipe joint of a kind of pressurized gas pipeline, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide that a kind of sealing is high, structure is simple, easy to use, the pressurized gas pipeline rapid pipe joint being suitable for gas on-site pipeline transformation and extending.
A kind of pressurized gas pipeline rapid pipe joint that the present invention proposes, comprise the joint body of inner hollow, it is characterized in that: the inside of described joint body is provided with all coaxial fixing back-up ring, a stopper and a movable sheath successively along pipeline direction of insertion, and described fixing back-up ring fixes inlay card on the inwall of joint body; On the inwall that the movable limiting card of described movable sheath is placed in joint body and can spacing movement vertically; Described stopper comprises a snap ring coaxial with pipeline, and the circumference of this snap ring is evenly equipped with the shell fragment that several extend to snap ring axial direction, this stopper is movably placed between fixing back-up ring and movable sheath, and this stopper can insert with pipeline and extract and move between movable sheath and fixing back-up ring.
As a further improvement on the present invention, described joint body is hollow tubular structure, and the perisporium of the pipeline insertion end of this hollow tubular structure forms rib towards sagittal plane turnover, joint body inwall is formed with a platform near this rib place, offer a circle groove near on the joint body inwall at this platform place, described fixing back-up ring fixes inlay card in this groove.
As a further improvement on the present invention, the bottom outer shroud of described fixing back-up ring is the flat embedded rings of a circle and matching grooves, this embedded rings upwards extends to form back-up ring platform, and the top inner ring of back-up ring platform upwards extends to form inverted-proof ring, described embedded rings inlay card in described groove, and is formed with gap between the outer wall of back-up ring platform and the inwall of joint body.
As a further improvement on the present invention, one first seal ring is arranged with inside described rib and between described embedded rings bottom surface.
As a further improvement on the present invention, the inwall that the movable limiting card of described movable sheath is placed in joint body can the structure of spacing movement vertically be: described movable sheath cylindrically, the bottom of this cylinder-like structure forms a circle position limit cycle, this position limit cycle activity is inserted in described gap, and be positioned on the movable sheath periphery wall above position limit cycle and be formed with a circle boss, the inwall of described joint body is formed with a circle chuck, boss is arranged between the embedded rings of chuck and fixing back-up ring, and boss can slide vertically between chuck and embedded rings.
As a further improvement on the present invention, when the bottom of described position limit cycle pushes against on the embedded rings of fixing back-up ring, be formed between described boss and chuck and slide spacing.
As a further improvement on the present invention, the upper end of described movable sheath periphery wall offers arc groove, is arranged with the second seal ring in this arc groove, and this second seal ring pushes against between movable sheath periphery wall and the inner circle wall of joint body.
By such scheme, the present invention at least has the following advantages: fix inlay card on the inwall of joint body by fixing back-up ring, on the inwall that the movable limiting card of movable sheath is placed in joint body and can spacing movement vertically, pipeline be inserted and frictional force in withdrawal process between this stopper and compressed pipe reduces, insertion pull action can be made very light, a snap ring coaxial with pipeline is comprised by stopper, and the circumference of this snap ring is evenly equipped with the shell fragment that several extend to snap ring axial direction, this stopper is movably placed between fixing back-up ring and movable sheath, and this stopper can insert with pipeline and extract and move between movable sheath and fixing back-up ring, make it fastening to the locking of pipeline, ensure the peace after logical liquid in pipeline, in this external pipeline withdrawal process, liquid heats can be avoided, stopper in dial-out process is prevented to be stuck in pipeline outer wall, pipeline is transferred to very light, this pressurized gas pipeline rapid pipe joint sealing is high, structure is simple, easy to use, be suitable for gas on-site pipeline transformation and extend using.
