Description
Technical field
The utility model relates to oilfield machinery, a kind of especially adjustable telescopic flange.
Background technique
Metering room replacing gate is a regular maintenance work, metering room gate is Flange joint, space is narrower and small, changes to get up not only to there is a lot of hidden danger, and affects crude oil production: one is that gate model is various, institute enters material and differs, flange aperture disunity, during installation, must cut away original flange, again to get angry welding, increase the number of times of getting angry of workload and metering room.Two is that flange thorn leaks when changing flange gasket, and the size between two flange gaskets is smaller, cleaning flange and to change flange gasket difficulty larger.Three is change in gate process, also there is gate connection highly to differ, need cutting or lengthen oil pipeline, particularly because gate model differs, causing pipeline height excessive, when needing to increase pipeline, one section of pipeline must be welded with, add welding job amount, not only inconvenient operation, and cause working efficiency low, waste time and energy.
Summary of the invention
For above-mentioned situation, for overcoming prior art defect, the object of the utility model is just to provide a kind of adjustable telescopic flange, and efficient solution can determine that to change operating gate inconvenient for metering room, working efficiency is low, the problem wasted time and energy.
The technological scheme that the utility model solves is, comprise box cupling, lower connector and flange, upper box cupling is the hollow columnar structures of both ends open, the inner chamber of upper box cupling is formed together with top inner chamber is coaxial docking with lower lumen, lower lumen wall there is internal thread, lower connector forms together with top cylinder is coaxial docking with bottom cylinder, the outer wall of top cylinder is circumferentially evenly equipped with groove, form convex-concave interphase structure, ring set is in groove, the outer wall of bottom cylinder there is outside thread, the top cylinder of lower connector is placed in the top inner chamber of box cupling, be tightly connected through seal ring, the bottom cylinder of lower connector is placed in the lower lumen of box cupling, external thread rotary on internal thread on lower lumen wall and the external wall of lower post is fitted together, form screwed connection structure, lower connector is fixed on flange.
The utility model structure is simple, novel unique, easy to use, easy to operate, time saving and energy saving, substantially increases working efficiency.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Fig. 2 is the structure sectional view of box cupling on the utility model.
Fig. 3 is the structure sectional view of the utility model lower connector.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Provided by Fig. 1-Fig. 3, the utility model comprises box cupling, lower connector and flange, upper box cupling 10 is the hollow columnar structures of both ends open, the inner chamber of upper box cupling is formed together with top inner chamber 1 is coaxial docking with lower lumen 2, lower lumen wall there is internal thread 3, lower connector forms together with top cylinder 4 is coaxial docking with bottom cylinder 5, the outer wall of top cylinder is circumferentially evenly equipped with groove 6, form convex-concave interphase structure, seal ring 7 is sleeved in groove, the outer wall of bottom cylinder there is outside thread 8, the top cylinder of lower connector is placed in the top inner chamber of box cupling, be tightly connected through seal ring, the bottom cylinder of lower connector is placed in the lower lumen of box cupling, external thread rotary on internal thread on lower lumen wall and the external wall of lower post is fitted together, form screwed connection structure, lower connector is fixed on flange 9.
The bore of described top inner chamber 1 is less than the bore of lower lumen.
Described top inner chamber 1 and the cross section of lower lumen are rectangle.
Described upper box cupling 10 is cylindrical.
Described flange 9 diameter is greater than the diameter of bottom cylinder.
Described groove 6 has 4, ringwise.
During installation, by upper box cupling and pipeline welding, lower connector is screwed in upper box cupling, upper box cupling is hollow cylinder, lower inner wall there is internal thread, 4 grooves are arranged at the top of lower connector, the bottom outer wall of lower connector there is outside thread, lower connector is connected with flange plate, pivot bottom joint, thus adjustment lower connector is screwed into the degree of depth in box cupling, to reach the height changed between flange on gate and the flange in the utility model, make flange gap suitable, reach the object of do not get angry quick-replaceable gate and flange gasket.
The utility model is simple to operate, easy to use, time saving and energy saving, and easily can realize cleaning flange and change flange gasket, working efficiency is enhanced about more than once, and has good economic and social benefit.
