Abstract

A leakage blocking instrument for a chemical industrial pipeline under pressure relates to a leakage blocking device for a chemical industrial pipeline, which comprises semicircular clamps, bolts and nuts. A through hole is arranged in the middle of each of the semicircular clamps, and an outer sleeve fits outside the through hole and is welded hermetically; a lock sleeve body is a pipe-shaped body, an outer edge of one end of the pipe-shaped body extends outward to form a ring disc integrally, and the pipe-shaped body of the lock sleeve body is provided with external threads corresponding to internal threads of the outer sleeve; a sealing barrel is a pipe-shaped body, a shaft shoulder is arranged in the middle of the pipe-shaped body, a sealing cover plate is fixed on an outer edge of the sealing barrel, and a through hole arranged at the center of the sealing cover plate is communicated with a decompression valve; an inner circle of a shaft-sleeve-shaped rubber sealing cover fits on an outer circle on an inner side section of the sealing barrel, an outer circle thereof fits on an inner circle of the outer sleeve, an inner end face thereof fits on an outer circle of a pipe to be blocked, and an outer end face thereof fits on an inner end face of the shaft shoulder of the sealing pipe; external threads of the lock sleeve body are screwed in internal threads of the outer pipe, and the inner circle of the lock sleeve is sleeved outside the outer circle of the outer side section of the sealing barrel in a clearance fit manner to abut and fix the inner end face of the shaft shoulder of the sealing pipe. Leakage blocking is performed under a non-high-pressure state.

Description

A kind of chemical pipeline pressure sealing utensil
Technical field:
The utility model relate to field pressure piping such as chemical industry not lay-by press leakage-baffling device.
Background technique:
Leakage is the problem that chemical enterprise must be attached great importance to; Medium is inflammable and explosive mostly, or be corrosive, toxicity, like ammonium carbamate solution of liquefied ammonia, semi-water gas, urea etc.; Leak and not only pollute the environment; Sometimes even the entail dangers to production safety, therefore take place to leak just must deal carefully with as early as possible, weld repairs is carried out in step-down, cooling, shutdown again behind system shutdown then be the general step of handling leakage.Chemical plant installations is a production procedure that continuity is very strong, and is stable for the production of enterprise, reduces economic loss, sums up method and the utensil that has accumulated many pressure sealings in practice.
Existing Plugging device is two semicircle clips, the clip internal diameter with treat that the plugging external diameter is identical, be fitted in the leak surface with a flat rubber during leak stopping, press a clip earlier after, another clip and its symmetry is fitted; Then in the outer plate hole of two semicircle clip two ends disjunctors, be inserted in bolt, and use nut check.There is following defective in this simple and easy utensil: the flat rubber plate with treat that plugging cylindrical faying surface is big, faying surface is difficult to fit fully too greatly on the contrary, possibly also can leak gas.Secondly, fitting to install still is under the high pressure conditions, and locking operation this moment difficulty is big.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned defective, and a kind of chemical pipeline pressure sealing utensil is provided.
The scheme of the utility model is: comprise two semicircle clips, lock and use bolt and nut; It is characterized in that: be provided with a through hole at a semicircle clip middle part; An internal diameter jacket tube Guan Yiduan intersecting line jointing type identical with through-hole diameter is fitted in implements the sealing welding on the through hole outer surface, the outer sleeve body the other end is provided with internal thread; The lock tube body is circle ring disk of a tubular body one end outer radially outward disjunctor extension, and the tubular body of lock tube body is provided with and the corresponding outside thread of outer sleeve internal thread, is uniformly distributed with several radial holes on the lock tube body circle ring disk; Sealing drum is the shaft shoulder that a tubular body middle part is provided with a disjunctor radial extension, and one of which side outer is fixed with the capping plate, and circle is Spielpassung in sealing drum shaft shoulder cylindrical and the outer sleeve, and relief tube fixing on the capping plate center through hole is communicated with a Decompression valves; Circle is fitted on the sealing drum medial segment cylindrical in sleeve-like rubber sealing boot, cylindrical is fitted in the outer sleeve body that circle is gone up, interior edge face be fitted in treat on the plugging cylindrical, the exterior edge face is fitted on the sealed pipe shaft shoulder interior edge face, the rubber sealing boot axial length is greater than sealing drum medial segment axial length; The lock tube extracorporeal thread is twisted and is combined in the outer sleeve internal thread, and the circle Spielpassung is enclosed within outside the sealing drum segmentum laterale cylindrical in the lock tube body, pastes sealed pipe shaft shoulder interior edge face top fixing.
The advantage of the utility model is: during leak stopping, and operation under non-high pressure conditions, plugging effect is good.As long as the plugging of treating to different tube diameters is provided with the semicircle frame of different inner diameters simultaneously.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
The utility model comprises two semicircle clips 1, locks and use bolt and nut; It is characterized in that: be provided with a through hole at semicircle clip 1 middle part; Internal diameter jacket tube pipe 4 one end intersecting line jointing types identical with through-hole diameter are fitted in implements the sealing welding on the through hole outer surface, the outer sleeve body the other end is provided with internal thread; Lock tube body 6 is circle ring disk of a tubular body one end outer radially outward disjunctor extension, and the tubular body of lock tube body 6 is provided with and the corresponding outside thread of outer sleeve 4 internal threads, is uniformly distributed with several radial holes on lock tube body 6 circle ring disks; Sealing drum 5 is the shaft shoulder that a tubular body middle part is provided with a disjunctor radial extension; One of which side outer is fixed with capping plate 7; Circle is Spielpassung in sealing drum 5 shaft shoulder cylindricals and the outer sleeve 4, and relief tube fixing on capping plate 7 center through hole is communicated with a Decompression valves 8; Circle is fitted on the sealing drum 5 medial segment cylindricals in sleeve-like rubber sealing boot 3, cylindrical is fitted in the outer sleeve body that circle is gone up, interior edge face be fitted in treat on plugging 2 cylindricals, the exterior edge face is fitted on the sealed pipe shaft shoulder interior edge face, rubber sealing boot 3 axial lengths are greater than sealing drum 5 medial segment axial lengths; Lock tube body 6 outside threads are twisted and are combined in outer sleeve 4 internal threads, and the circle Spielpassung is enclosed within outside the sealing drum 5 segmentum laterale cylindricals in the lock tube body 6, paste sealed pipe shaft shoulder interior edge face top fixing.
Because rubber sealing boot 3 axial lengths are greater than sealing drum 5 medial segment axial lengths, so treat the compressing sealing between plugging 2, outer sleeve body, sealing drum 5 threes.
During leak stopping, it is peripheral that circle in the sealing drum 5 is aimed at leakage hole, opens Decompression valves 8 pressure releases, turns lock tube body 6 again after two semicircle clips 1 are fixedly connected in advance, just can rubber sealing boot 3 pressings be close to.These operations are all carried out not being with under the pressure condition, Decompression valves 8 cut out behind the fixing and locking end of operation again, just accomplish the leak stopping operation.The characteristic of considered leaking medium in practical operation adopts rubber, graphite fiber, teflon or other suitable sealing materials.
The pressure leakage point is closed in the sealing drum 5, realizes sealing.
