Abstract
The utility model relates to a fast pipe sealing connector which belongs to the pipe connection device. The utility model comprises a sealing sleeve with a convex platform which is arranged at the inner side of the connection part of two pipes, a nut which is fixed at the inner inclined plane of the pipe external side. A protection ring which is sleeved on the convex platform of the sealing sleeve is arranged outside the connection part of two pipes. One of the two inner inclined plane fastening nuts outside the protection ring is provided with an inner thread, the other is provided with corresponding outer thread. The two fastening nuts are mutually sleeved directly by screw threads. The utility model provides the advantages of simple and compact structure, low cost, more convenient operation, fast construction sped, good sealing performance, high connection strength, good safety and reliability, and wide application range. The utility model is suitable for connections of different transportation pipelines which transport materials of high temperature and pressure, and strong corrosion.
Description
Technical field
The utility model relates to a kind of pipeline rapid seal connector, belongs to assembling pipe joint.
Background technique
Along with the development of pipeline connection technology, emerged the multiple quick Placement of pipeline, easy construction, labor intensity is little.What great majority adopted at present is to coat stuffing box gland at jointing, then stuffing box gland is carried out fastening mode, and this Placement still is must be on-the-spot at pipeline opening end mantle fiber, and Sealing easily damages by pressure, poor sealing performance.These Placements can not be protected the coating of inner-walls of duct well worse, as mantle fiber destruction etc., therefore can not solve the pipeline connectivity problem of water supply, oil, chemical industry, combustion gas field high temperature, high pressure, strong corrosive medium well.The patent No. of the applicant's design is the pipe fitting quick-sealing coupling arrangement of ZL99220830.0, adopted the casing seal of built-in band boss, mantle fiber steel pipe and the interior inclined-plane fastening nut tension of upward installing, fastening thereof by the outside suit in two interface tube places have solved the problems referred to above preferably.But the inclined-plane fastening nut needs to realize being fastenedly connected by the steel pipe of outside mantle fiber respectively in two, complex structure, and cost is higher, and operation inconvenience influences speed of application.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple and compact for structure, and more convenient operation, speed of application is faster and join strength is big, the pipeline rapid seal connector that safety reliability is good.
Pipeline rapid seal connector described in the utility model; comprise the stuffing box gland of the band boss that is placed in two pipeline connecting part insides of pipes, the interior inclined-plane fastening nut in the pipeline outside; its pipeline outside, two pipelines connecting part is provided with; the guard ring cover is buckled on the boss of stuffing box gland; two one of the interior inclined-plane fastening nut in the guard ring outside have internal thread; another has corresponding outer silk, and two fastening nuts are directly screw thread socket mutually.
On two interior inclined-plane fastening nuts, the outer silk of band, a band internal thread, both are directly screw thread socket mutually, only can finish installation, disassembling section with spanner, and simple in structure, easy to operate, speed of application is faster.
For elbow, three-way pipe, but simplified structure, be equipped with supporting elbow and three-way pipe, that is: outer nut in the interior inclined-plane fastening nut that the outer silk of the seam of elbow, three-way pipe cover double as is threaded mutually, can save inclined-plane fastening nut in the outer silk, simplified structure has reduced cost, the connection of easy greatly elbow, three-way pipe.
The utility model has still adopted the stuffing box gland of built-in band boss; and be added with and prevent that boss is squeezed and outstanding guard ring; strengthen the sealing effect of mouth of pipe end; obtain the better seal performance; when especially stuffing box gland is selected identical material for use with pipe internal coating; can realize the fusion Placement of stuffing box gland and pipe internal coating, form one, further improve sealability.Simultaneously, guard ring has been strengthened whole join strength, has prevented the mouth of pipe offset phenomena that occurred by external force because of pipeline, firm and reliable connection.
The utility model is simple and compact for structure, and cost is low, more convenient operation, and speed of application is faster, and sealability is better, and join strength is big, and safety reliability is good, and is applied widely, is applicable to the connection of various medium transport pipelines such as high temperature, high pressure, strong corrosive medium.
Description of drawings
Application state structural representation when Fig. 1, the utility model are used for the straight tube connection.
Application state structural representation when Fig. 2, the utility model are used for the elbow connection
Fig. 3, the suitable three-way pipe structure schematic representation of the utility model
Among the figure: 1,2 interior inclined-plane fastening nuts, 3 guard rings, 4 stuffing box glands, 5 back-up rings, 6 straight tubes, 7 elbows, 8 three-way pipes.
Embodiment
Be described further below in conjunction with embodiment's accompanying drawing.
As shown in Figure 1; pipeline rapid seal connector described in the utility model; comprise the stuffing box gland 4 of the band boss that is placed in two pipeline connecting part insides of pipes, the interior inclined-plane fastening nut 1,2 in pipeline 6 outsides; its pipeline outside, two pipelines connecting part is provided with guard ring 3; guard ring 3 covers are buckled on the boss of stuffing box gland 4, and there is inclined-plane fastening nut 1,2 in two in guard ring 3 outsides, on the interior inclined-plane fastening nut 1 internal thread are arranged; corresponding outer silk is arranged on the interior inclined-plane fastening nut 2, and both are directly screw thread socket mutually.
Be operating as example to connect straight tube; length according to interior inclined-plane fastening nut 1; nose end certain position processing annular groove (or pit) at the distance pipeline; elder generation is respectively with interior inclined-plane fastening nut 1 during tipping; 2 covers install to pipe ring groove rear portion; again back-up ring 5 (or fixedly steel ball) card is put in the annular groove (or pit); guard ring 3 is sleeved on the port of pipeline 6; stuffing box gland 4 covers of band boss are installed in the pipeline 6; the boss card is placed on two pipelines, 6 joints; mobile guard ring 3 is to the boss place of stuffing box gland 4; rotate fastening nut 1 or/and fastening nut 2, two nuts 1; 2 relative precessions.Simple and compact for structure, more convenient operation, speed of application is faster.Along with the precession of fastening nut, its rear portion chucking back-up ring 5 (or fixedly steel ball), and drive two connecting tubes and move to the centre, till screwing.Under the extruding of two connecting tubes 6, the boss of stuffing box gland 4 is stressed outwards outstanding, and guard ring 3 will be given prominence to envelope and push down, and play better seal action, and strengthen join strength, and will be safe and reliable.
For connecting bend, three-way pipe, shown in Fig. 2,3, can be equipped with supporting elbow and three-way pipe, that is: inclined-plane fastening nut in outside the outer silk of the seam of elbow 7, three-way pipe 8 cover double as thread, save inclined-plane fastening nut in the outer silk, simplified structure has reduced cost, the connection of easy greatly elbow, three-way pipe, fitting operation is more convenient.
