Abstract
The invention relates to a pipeline free end sealing device which comprises supporting blocks, a spring, cover boards, a bolt and a compression nut. Two supporting blocks are symmetrically hinged to one end of the bolt; the compression nut is screwed at the other end of the bolt; the cover boards are arranged between the compression nut and the supporting blocks; and the cover boards are pressed against between the two supporting blocks and the compression nut by the spring. The bolt is screwed by the nut to drive the cover boards to package orifices of a pipeline and the spring is abutted against the supporting blocks to clamp the inner wall of the pipeline in a matching way, so that the fastening connection is implemented; the pipeline free end sealing device has simple integral structure, is convenient to manufacture and use, can be used on various leakage test pipelines and can be repeatedly used; and the using cost is reduced.
Description
Technical field
The present invention relates to a kind of close property device, is a kind of free-ended close property device of closed conduit that is used for specifically.
Background technique
In the shipbuilding process, some is the free end shutoff at pipe for the close property of pipeline.The method that tradition is used is that free end is welded extremely with baffle plate, treats through the method for flame cutting shrouding to be cut off after tightness test is accomplished, and then with polisher polished in the scarfing position that there is following drawback in this kind method:
1), waste material and man-hour;
2), the flame cutting is prone to mounted equipment and decoration plate cause damage on every side;
3), the iron oxide that forms of flame cutting is prone to get into tube interior because this type of pipe all is that Socket welding is dead, therefore can't it be gone out clearly.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this invention is to provide a kind of simple in structurely, easy to make, easy to use, labor intensity is low, and is reusable, the free end of pipeline sealing device that user cost is low.
For achieving the above object; The technological scheme that the present invention adopts is: a kind of free end of pipeline sealing device; It is characterized in that comprising support block, spring, cover plate, bolt and gland nut, two support block symmetries are articulated in bolt one end, and the bolt the other end is screwed with gland nut; Be provided with cover plate between gland nut and the support block, cover plate through spring top clamping between two support blocks and gland nut.
Said support block is movable rotation and is resisted against on the base of bolt one end.
Be provided with rubber sheet gasket between said spring and the cover plate.
Be provided with pad between said gland nut and the cover plate.
Said spring pushes against two support blocks through catch.
Non-spring one side of said cover plate is provided with the seal rack that gland nut is contained in sealing, is connected with the sealing bolt of band gasket seal on the seal rack.
When the present invention uses, select corresponding support block, close property device support block is articulated on the bolt and pushes against base, put into pipeline according to the diameter of required test pipeline; Fastening gland nut; Because the relative movement of bolt and cover plate causes length of spring compressed, spring masterpiece by compression is used for pad, is passed on the support block in the process of fastening gland nut; Make support block rotate and spacing by base around articulating point, support block opens with inner tube wall and tightly engages; Continue fastening gland nut, the stressed mouth of pipe with pipeline of rubber gasket this moment is fitted, and sealing bolt and gasket seal are tightened the sealing seal rack, and so far the free end of pipeline is by sealing fully.
This close property device adopts nut to screw bolt and drives the cover plate encapsulation pipeline mouth of pipe, cooperates spring to push against support block chucking pipeline inner wall and realizes being fastenedly connected, and overall structure is simple; Making, easy to use; Can be used on the pipeline of all kinds of seal tightness tests, reusable, reduce user cost.
