According to the rotary expanding-clamping device for the tube plug in the scheme of the utility model, the expanding blocks are uniformly arranged on the tube plug along the circumferential direction; the same end of each expanding block is arranged rotationally on the tube plug; when the driving disk rotates, the other end of each expanding block can be driven to rotate outwards to be clamped in a clamping groove of a tube joint, so that the tube plug is fixed; the rotary expanding-clamping device is convenient to install, the conventional complex tube joint machining processes are reduced, and leaking points of the tube joint are reduced.
Description
Technical field
The utility model relates to a kind of improvement of pipe close fixing device, refers in particular to a kind of convenient installation, has reduced the pipe joint processing technology of complexity in the past, has reduced again the rotary card device that rises for pipe close of pipe joint leakage point.
Background technique
Stopping transportation plugging holes equipment, has not been widely used in burning line operation under pressure at present.Its main auxiliary equipment band gas perforate, shutoff pipe connect (abbreviation pipe joint).
Pipe joint is arranged on pipeline, and for sandwich valve and perforator or plugging device provide a fixed bearing, it is furnished with pipe close, and after operation completes, pipe close can block the medium in pipeline by certain mechanism, is convenient to be folded down the equipment such as sandwich valve.
The main fixed form of the pipe close of current domestic use pipe joint is pin, lock ring type, and it is that pin, lock ring by being arranged in pipe coupling flange blocks or block pipe close after stretching out by certain mechanism ecto-entad, fixedly pipe close.Because pin, lock ring mechanism must install from flange is outside, though there is sealing mechanism, the damage of Sealing or aging meeting cause the leakage of gas medium, and a few cover pins, lock ring mechanism just may have several leak points.And due to the installation of pin, lock ring mechanism, can cause the thickness of flange to increase, improve the manufacture cost of product.
Model utility content
The utility model object is that a kind of convenient installation is provided in order to overcome the deficiencies in the prior art, has reduced the pipe joint processing technology of complexity in the past, has reduced again the rotary card device that rises for pipe close of pipe joint leakage point.
For achieving the above object, the technical solution adopted in the utility model is: the rotary card device that rises for a kind of pipe close, comprises driving disc; Described driving disc can be rotatably set on pipe close; On described pipe close, be along the circumferential direction provided with equably a plurality of pieces that rise; Described each piece that rises can be rotatably set on driving disc with one end; When driving disc rotates, the other end of described each piece that rises can outwards screw out.
Preferably, on described each piece that rises, be equipped with chute, on described driving disc, on the position of corresponding each piece that rises, be provided with the second bearing pin, described the second bearing pin inserts in chute, and can be along runner movement; When driving disc rotates, the bearing pin for the second time of described each piece that rises, along each self-corresponding runner movement, can outwards screw out the other end of each piece that rises.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The rotary card device that rises for pipe close described in the utility model scheme, is along the circumferential direction provided with a plurality of pieces that rise equably on described pipe close; Described each piece that rises can be rotatably set on pipe close with one end; When driving disc rotates, the other end of described each piece that rises can outwards screw out in the draw-in groove that snaps in pipe joint, thereby realizes fixing pipe close; The utility model is convenient to be installed, and has reduced the pipe joint processing technology of complexity in the past, has reduced again pipe joint leakage point.
