Abstract
The invention discloses a rotation type tensioning-clamping device for a pipe stopper. The rotation type tensioning-clamping device comprises a driving plate which is arranged on the pipe stopper in a rotating mode. A plurality of tensioning blocks are evenly arranged on the pipe stopper in the peripheral direction. The same end of each tensioning block is arranged on the pipe stopper in a rotating mode. When the driving plate rotates, the other end of each tensioning block is screwed out towards the outside. According to the rotation type tensioning-clamping device for the pipe stopper, the tensioning blocks are evenly arranged on the pipe stopper in the peripheral direction, the same end of each tensioning block is arranged on the pipe stopper in the rotating mode, and when the driving plate rotates, the other end of each tensioning block is screwed out towards the outside and clamped into a clamping groove of a pipe joint, so that the pipe stopper is fixed. The rotation type tensioning-clamping device is convenient to install, and reduces former complex machining processes of the pipe joint and leakage points of the pipe joint.
Description
Technical field
The present invention relates to a kind of improvement of pipe close fixing device, refer in particular to a kind of convenient installation, reduced pipe joint complicated processing technology in the past, the pipe close that has reduced the pipe joint leakage point again is with the rotary card device that rises.
Background technique
Stopping transportation perforate shutoff equipment has not been widely used in the burning line operation under pressure at present.Its main auxiliary equipment band air to open hole, shutoff pipe connect (abbreviation pipe joint) and are and perforator, the matching used piping attachment of plugging device.
Pipe joint is installed on the pipeline, and for sandwich valve and perforator or plugging device provide a fixed bearing, it is furnished with pipe close, and pipe close can block medium in the pipeline by certain mechanism after operation was finished, and was convenient to be folded down equipment such as sandwich valve.
The main fixed form of the pipe close of present domestic use pipe joint is pin, lock ring type, and it is to block or block pipe close by pin, the lock ring that is installed in the pipe coupling flange after stretching out by certain mechanism ecto-entad, fixedly pipe close.Because pin, lock ring mechanism must install from flange is outside, though sealing mechanism is arranged, the damage of Sealing or the aging leakage that can cause the combustion gas medium, a few cover pins, lock ring mechanism just may have several leak points.And because the installation of pin, lock ring mechanism can cause the thickness of flange to increase, improved the manufacture cost of product.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of convenient installation, reduced pipe joint complicated processing technology in the past, the pipe close that has reduced the pipe joint leakage point again is with the rotary card device that rises.
For achieving the above object, the technical solution used in the present invention is: a kind of pipe close comprises driving disc with the rotary card device that rises; Described driving disc can be rotatably set on the pipe close; Along the circumferential direction be provided with a plurality of pieces that rise on the described pipe close equably; The same end of described each piece that rises can be rotatably set on the driving disc; When driving disc rotated, the other end of described each piece that rises can outwards screw out.
Preferably, be equipped with chute on described each piece that rises, the position of corresponding each piece that rises is provided with second bearing pin on the described driving disc, and described second bearing pin inserts in the chute, and can be along runner movement; When driving disc rotates, described each piece that rises the second time bearing pin along each self-corresponding runner movement, the other end of each piece that rises can outwards be screwed out.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
The described pipe close of the present invention program along the circumferential direction is provided with a plurality of pieces that rise equably with the rotary card device that rises on the described pipe close; The same end of described each piece that rises can be rotatably set on the pipe close; When driving disc rotated, the other end of described each piece that rises can outwards screw out in the draw-in groove that snaps in pipe joint, thereby realized fixing pipe close; The present invention is convenient to install, and has reduced the pipe joint processing technology of complexity in the past, has reduced the pipe joint leakage point again.
