Abstract
The utility model relates to a sealing device of the free end of channel. The sealing device of the free end of channel comprises supporting blocks, springs, cover plates, bolts and gland nuts. Two supporting blocks are symmetrically connected with one end of the bolt in hinge mode. The gland nuts are screwed at the other end of the bolt. The cover plate is placed between the gland nut and the supporting blocks. The cover plate is tightly twisted between the two supporting blocks and the gland nuts. The Nut screws into the bolt to drive the plate mouth of the packaging channel of the cover plate together with the spring tightly twisting the supporting blocks and chucking the inner wall of the channel, thereby achieving fixed connection. The sealing device of the free end of channel has the advantages of being simple in structure, easy to manufacture and use, capable of being applied to the channels used on a plurality of sealing experiments.
Description
Technical field
The utility model relates to a kind of close property device, is a kind of for the free-ended close property device of closed conduit specifically.
Background technique
In the shipbuilding process, some is free end shutoff at pipe for the close property of pipeline.The method that tradition is used is that free end is welded with baffle plate, treats by the method for flame cutting shrouding to be cut off after tightness test is finished, and then with polisher is polished in the scarfing position, and there is following drawback in this kind method:
1), waste material and man-hour;
2), the flame cutting is easily to mounted equipment and decorating board cause damage on every side;
3), the iron oxide that forms of flame cutting easily enters tube interior because this type of pipe all is that sleeve pipe is welded, therefore it can't be cleared out.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model provides a kind of simple in structure, and is easy to make, easy to use, and 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 technical solution adopted in the utility model 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, 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.
Described support block is on the base that moving rotary is resisted against bolt one end.
Be provided with rubber sheet gasket between described spring and the cover plate.
Be provided with pad between described gland nut and the cover plate.
Described spring pushes against two support blocks through catch.
Non-spring one side of described cover plate is provided with the seal rack that gland nut is contained in sealing, is connected with the sealing bolt with gasket seal on the seal rack.
When the utility model uses, select corresponding support block according to the diameter of required test pipeline, be articulated in close property device support block on the bolt and push against base, put into pipeline; Fastening gland nut, because the relative movement of bolt and cover plate causes spring-compressed, spring by compression masterpiece is used for pad, is passed on the support block in the process of fastening gland nut, so that support block rotates 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 completely sealed.
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.
