Abstract
The utility model relates to a rapid sealing connecting device for pipe fittings. The utility model is characterized in that a sealing piece is a teflon sleeve pipe with protrusions arranged around the outer part; a fastening piece is a short steel pipe with a thread sheathed on the outer part; the short steel pipe is sheathed on a pipe with smooth end heads; fastening nuts are symmetrically sheathed at both ends of the outer part of the short steel pipe through screw threads; inclined planes on the back parts of the fastening nuts are sheathed on the smooth pipe, and positioning pieces are installed on pipes on the front parts of the inclined planes. The utility model has the advantages of simple and compact structure, convenient installation and maintenance, suitability for various environments and pipelines with various pipe diameters, and favorable sealing performance, and threads don't need to be sheathed on the pipelines on site.
Description
The utility model belongs to Pipe jointing part, specifically is a kind of pipe fitting quick-sealing coupling arrangement.
The connection of present various pipelines, mainly be to adopt at pipe end welding upper flange, bellmouth or screw thread, lay sealing gasket at each pipe end then, and again two pipelines are fixedly connected with bolt or sleeve pipe and are one, or two pipelines directly are welded as a whole, there is the pipeline that can only be applicable to little caliber in these several mounting types, when being used for field work, need the on-the-spot two ends of pipeline of giving to cut silk, increased working strength of workers, its application area is very restricted, and this connecting mode not only difficulty of processing is big, operation is loaded down with trivial details, structure is complicated, and because tube wall is thinner, when connecting, pushes in pipeline bad Sealing easily, be difficult to guarantee the leakproofness that seals, though also have in the market at the quick device that connects of the pipeline of various calibers, but be mostly to adopt and coat stuffing box gland at jointing, then stuffing box gland is carried out fastening mode, this coupling arrangement has still existed necessary scene at the pipe ends mantle fiber, Sealing easily damages by pressure, poor sealing performance can not solve high temperature, pipeline articulation issues in high pressure or the high corrosive environment.
It is a kind of simple and compact for structure that the purpose of this utility model is to provide, installation, easy to maintenance, and good airproof performance is applicable under the various environment, the pipeline of various calibers connects, and does not need the pipe fitting quick-sealing coupling arrangement of mantle fiber on pipeline.
The utility model is achieved through the following technical solutions:
It is a kind of pipe fitting quick-sealing coupling arrangement, comprise Sealing, inclined-plane fastening nut and fastening piece, Sealing is placed in two pipeline connecting parts, the outside of pipeline connecting part is installed fastening piece and inclined-plane fastening nut successively, it is characterized in that Sealing is the bossed teflon sleeve of ring external process, fastening piece is the short steel pipes of outside mantle fiber, short steel pipes is sleeved on the level and smooth pipeline in termination, outside by screw thread at two ends symmetry suit fastening nut, the inclined-plane at fastening nut rear portion is sleeved on the level and smooth pipeline, and on the pipeline of front portion, inclined-plane the installing and locating part.
The inwall of described Sealing is slick and sly arcuate structure from the middle part to two ends.
The utility model compared with prior art, owing to adopted the Sealing of the sleeve structure of built-in band boss, the inclined-plane fastening nut tension of passing through the mantle fiber steel pipe of the outside suit in two interface tube places then and upward installing, fastening, strengthened the sealing area of mouth of pipe end, pipe ends does not need to cut silk to be handled, so have the following advantages:
1, simple and compact for structure, installation, easy to maintenance.
2, be applicable under the various environment pipeline of various calibers, good airproof performance.
Describe in further detail below in conjunction with accompanying drawing:
Fig. 1: the utility model mounting structure schematic representation.
Among the figure: 1 inclined-plane fastening nut, 2 fastening pieces, 3 Sealings, 4 pipelines, 5 annular grooves (fixed hole), 6 back-up rings (steel ball)
Before the tipping small-caliber pipeline, length according to inclined-plane fastening nut 1 inclined-plane, go up annular groove 5 apart from the port certain position processing of pipeline respectively, when tipping, respectively fastening nut 1 cover in inclined-plane is installed to pipe ring groove 5 rear portions earlier, and then back-up ring 6 card is put in the annular groove 5, and therein on the pipeline 4 cover load onto the internal diameter fastening piece 2 identical with pipeline 4 external diameters, Sealing 3 covers of the external diameter band boss identical with pipeline 4 internal diameters are installed in the pipeline 4, then the boss card is placed on two pipelines, 4 joints, rotate two fastening nuts 1, make the silk inwards precession of fastening nut 1 along fastening piece 2, because of fastening nut 1 rear portion is the inclined-plane, (prior art constructions form) thus along with the precession of fastening nut 1, its rear portion chucking back-up ring 6, and drive ganoid two pipelines 4 and all move to the centre, until fastening nut 1 turn can get at better sealing till, under the extruding of two pipelines 4, the boss of Sealing 3 is stressed to outer lug, thereby extruding fastening piece 2 plays better seal action.
Before the tipping big-diameter pipeline, length according to inclined-plane fastening nut 1 inclined-plane, (about 2/3 of diameter of the steel ball gets final product deeply to go up fixed hole 5 apart from the port certain position of pipeline with the processing of brill symmetry respectively, and can not penetrate pipeline), when tipping, respectively fastening nut 1 cover in inclined-plane is installed to fixed hole 5 rear portions of pipeline earlier, and then steel ball 6 is placed in the fixed hole 5, and therein on the pipeline 4 cover load onto the internal diameter fastening piece 2 identical with pipeline 4 external diameters, Sealing 3 covers of the external diameter band boss identical with pipeline 4 internal diameters are installed in the pipeline 4, then the boss card is placed on two pipelines, 4 joints, rotate two fastening nuts 1, make the silk inwards precession of fastening nut 1 along fastening piece 2, because of fastening nut 1 rear portion is the inclined-plane, (prior art constructions form) is so along with the precession of fastening nut 1, its rear portion chucking steel ball 6, and drive ganoid two pipelines 4 and all move to the centre, until fastening nut 1 turn can better seal till, under the extruding of two pipelines 4, the boss of Sealing 3 is stressed to outer lug, thereby extruding fastening piece 2 plays better seal action.
The inwall of Sealing 3 is slick and sly arcuate structure, resistance in just will managing is reduced to minimum as much as possible, and in pipe, also can produce an outside pressure after the pressurization to Sealing 3, boss on Sealing 3, make Sealing 3 play the double seal effect, Sealing 3 adopts teflon to make, not only solved high temperature, high pressure, pipeline articulation issues under the high corrosive environment, nor the anticorrosion coating or plating layer of destruction inner tube wall, effectively prolonged the working life of pipeline, pipe surface need not cut silk and handle, and has promptly reduced working strength of workers, has improved work efficiency simultaneously yet.
Claims (2)
1, a kind of pipe fitting quick-sealing coupling arrangement, comprise Sealing, inclined-plane fastening nut and fastening piece, Sealing is placed in two pipeline connecting parts, the outside of pipeline connecting part is installed fastening piece and inclined-plane fastening nut successively, it is characterized in that Sealing is the bossed teflon sleeve of ring external process, fastening piece is the short steel pipes of outside mantle fiber, short steel pipes is sleeved on the level and smooth pipeline in termination, outside by screw thread at two ends symmetry suit fastening nut, the inclined-plane at fastening nut rear portion is sleeved on the level and smooth pipeline, and on the pipeline of front portion, inclined-plane the installing and locating part.
