Description
Technical field
This utility model relates to field of petroleum machinery, in particular it relates to a kind of based on the gripping mechanism improving sealing.
Background technology
Oil after exploitation is in transportation, owing to the route of transport is long, petroleum pipeline for transporting generally adopts multisection type pipeline to transport, namely multisection type pipeline adopts many segment pipes to be formed by connecting, one end of pipeline is provided with outer pitch thread, the other end is provided with intrinsic pressure screw thread, and adjacent two pipelines realize the connection of pipeline by the cooperation of interior pitch thread and outer pitch thread.Owing to oil transportation having bigger pressure, in order to improve the structural stability of pipeline junction, it usually needs pipeline junction is provided with gripping mechanism, it is used for reinforcing junction, it is to avoid pipeline junction comes off in petroleum transportation process.
Existing gripping mechanism generally adopts bolt to fix, troublesome poeration, and sealing is poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of based on the gripping mechanism improving sealing, with the problem overcoming the operation inconvenience of existing gripping mechanism, sealing difference.
The technical scheme in the invention for solving the above technical problem is: based on the gripping mechanism improving sealing, including 2 arcuate structures cooperated, 2 arcuate structure one end are hinged, the other end is provided with lug, one of them lug is hinged with fixing bar, fixing bar is provided with tapped through hole I, another lug offers the U-lag coordinated with fixing bar, the sidewall of U-lag is provided with the tapped through hole II coordinated with tapped through hole I, fixing bar is bolted in U-lag, the inwall of described arcuate structure is provided with rubber blanket, described rubber blanket is set to ledge structure, the sidewall of ledge structure is provided with arc convex.
The existing gripping mechanism for petroleum transportation pipeline junction is typically with 2 semi-circular structure separately, the two ends of 2 semi-circular structure are fixed by multiple bolts, adopting said structure to need tighting a bolt one by one when being fixed pipeline junction, troublesome poeration, sealing is also poor；2 arcuate structures cooperated described in the utility model specifically refer to 2 arcuate structures and just surround a circular configuration and coordinate with pipeline outer wall；nullDescribed ledge structure specifically refers to rubber blanket and just coordinates with the outer wall of pipeline junction，Pipeline junction is set in the pipeline outer wall of relatively pipe with small pipe diameter by the pipeline then passing through relatively Large Diameter Pipeline，And then form ring-shaped step at pipeline junction，Ledge structure described in the utility model is just fitted with ring-shaped step，The sidewall of described ledge structure specifically refers to the face of ledge structure and the laminating of pipeline sagittal plane，Be conducive to improving the sealing of pipeline junction by being provided with arc convex at the sidewall of ledge structure，Work process of the present utility model: 2 arcuate structures are placed on the junction of pipeline，The ledge structure of rubber blanket is arranged on the ring-shaped step place of pipeline junction，Arc convex is made to be fitted on the annular radial face of large-size pipeline，Rotating arcuate structure makes 2 lugs cooperate，Then pass through bolt to be fixed in U-lag by fixing bar and then realize gripping mechanism and fixed by pipeline junction，Owing to being provided with rubber blanket，Rubber blanket is set to ledge structure，The sidewall of ledge structure is provided with arc convex，Can not only avoid arcuate structure directly and frictionally damage that tube contacts causes，And under the effect of extruding rubber blanket, improve the sealing of gripping mechanism，Liquid is avoided to flow out from the gap of pipeline junction，This utility model is by arranging 2 arcuate structures being hinged，The movable end of arcuate structure arranges the fixing bar and U-lag that cooperate，By bolt, fixing bar is fixed in U-lag and then realizes gripping mechanism and pipeline junction is fixed，Simple in construction，Easy to operate，So，This utility model overcomes the operation inconvenience of existing gripping mechanism、The problem of sealing difference.
Further, arcuate structure inwall is provided with groove, and rubber blanket stupefied coordinates the inwall being fixed on arcuate structure with groove by convex.
Guarantee the fastness that rubber blanket is fixing.
Further, the surface configuration of rubber blanket is flank.
Flank can effectively increase the frictional force of contactant, it is to avoid the problem occurring skidding.
Further, being provided with inner sleeve in arcuate structure, the width of inner sleeve is more than the width of arcuate structure, and described rubber blanket is arranged in inner sleeve.
The setting of inner sleeve can increase the contact area of gripping mechanism and pipeline, improves the structural stability of gripping mechanism and fixing fastness.
Further, inner sleeve adopts politef to make.
Politef is prior art material, has corrosion resistant advantage, can improve the service life of poly-inner sleeve.
Further, arcuate structure adopts hard aluminium alloy to make.
Hard aluminium alloy is prior art material, the advantage with the big light weight of hardness, reduces its weight under meeting the premise of intensity of arcuate structure, it is simple to use.
To sum up, the beneficial effects of the utility model are:
1, this utility model is by arranging 2 arcuate structures being hinged, the movable end of arcuate structure arranges the fixing bar and U-lag that cooperate, by bolt, fixing bar is fixed in U-lag and then realizes gripping mechanism and pipeline junction is fixed, simple in construction, easy to operate.
2, this utility model is provided by rubber blanket, rubber blanket is set to ledge structure, the sidewall of ledge structure is provided with arc convex, can not only avoid arcuate structure directly and frictionally damage that tube contacts causes, and under the effect of extruding rubber blanket, improving the sealing of gripping mechanism, it is to avoid liquid flows out from the gap of pipeline junction.
