Pressurized container or the sealing of pipeline equal pressure equipment generally can be adopted direct welding closure plate mode or adopt the blank flange mode.On the actual engineering; A lot of middle and high pressure vessels and piping design adopt the welding manner pipe arrangement usually; And the middle and high pressure vessel of manufactured good or pipeline do not allow on-the-spot arbitrarily welding, otherwise can destroy the end face of tankage or pipeline, so adopt the mode of directly welding closure plate often infeasible.The blank flange sealing means is applicable to needs sealing part to be designed with the situation of flange, and sealing part does not have flange if desired, just need pressurized container or pipeline be carried out pipe arrangement, up to being designed with the position that flange connects, again with blank flange with its shutoff.This kind method is actual to have increased vacant pipeline, and this just in time deviates from the demand that reduces vacant equipment; Not only need professional qualification piping erection personnel to construct, pressure piping construction management standard and evidence obtaining work are caused certain difficulty, and workload is bigger, the actual inconvenience of implementing.And in actual engineering in often a lot of very long distances of pipe-line in addition the whole piece pipe-line do not design flange, adopt the mode of pipe arrangement blank off flange more infeasible in this case.
Summary of the invention
The utility model problem to be solved provides a kind of interim blocking device of pressurized container or pipeline; It has overcome traditional direct welding closure plate or has adopted the deficiency of blank flange sealing means; Equipment itself not being caused damage and do not increase under the situation of vacant equipment, realized effective sealing of equipment itself.
A kind of interim blocking device of the utility model pressurized container or pipeline is characterized in that: it comprises clamping screw, gland nut, pressing plate, Hough screw rod, haff nut, left half Hough, right half Hough, left half flange, right half flange, valve; The Hough screw rod passes the back with haff nut and tight from a left side half Hough, both relative lugs of right half Hough, a left side half Hough, right half Hough are pressed on the external diameter of pressurized container or pipeline; A left side half flange, right half flange are welded on the outside of left half Hough, right half Hough respectively, and both are through clamping screw, gland nut and be arranged on pressurized container or the pressing plate of pipeline end face links to each other; Valve passes the back through pipe from pressing plate and communicates with the end face of pressurized container or pipeline.
The utility model has been realized sealing through the end face that makes pressing plate be pressed on pressurized container or pipeline earlier; Form the certain pressure secluding air through pipe and valve to pressurized container or pipe interior inert gas injecting then, thereby realize the antirust of container or pipe interior.Therefore this device has overcome the deficiency that traditional direct welding closure plate perhaps adopts the blank flange sealing means, equipment itself not being caused damage and do not increase under the situation of vacant equipment, has realized the temporary sealing of equipment effectively.
