Abstract
The invention relates to a steel pipeline for integrally replacing a prestressed concrete cylinder pipe (PCCP) or combining pipelines. A steel-structured replacement pipe consists of a steel structure pipe (1), a limiting steel ring I (2), a sealing rubber ring I (3), a bellmouth component I (4), a stop block I (5), a bolt (6), a limiting steel ring II (7), a sealing rubber ring II (8), a bellmouth component II (9) and a stop block (10). By the steel-structured replacement pipe, the problem that socket welding type butting assembly is difficult to use because of a limited assembly space when a broken pipeline is integrally replaced or pipelines are combined is effectively solved; and furthermore, the assembly efficiency can be effectively improved, and the assembly difficulty is reduced.
Description
Technical field
The present invention relates to the steel pipe used when whole joint replacement of a kind of Prestressed concrete cylinder pipe (be called for short PCCP) or pipeline close up.
Background technique
At present, PCCP is widely used in various water delivery lines, and it has certain probability to have an accident in running, serious damage or booster occur like the pipe shaft of certain pipe joint, causes this pipe joint road must integral replacing.When broken pipe being carried out the integral body replacement, because PCCP belongs to spigot-and-socket joint, after taking off, damaged tube coupling do not have the space to replace an identical spigot and socket type tube coupling again, need think additive method in addition.Simultaneously, when pipeline closes up,, directly adopt spigot and socket type butt joint installation difficulty also bigger because the space is limited.Be necessary to develop a kind of specialized application in the tubing that broken pipe integral body is replaced or pipeline closes up to above-mentioned situation.
Summary of the invention
The objective of the invention is to design a kind of can effectively the solution and close up when installing,, be difficult to the problem that adopts the spigot and socket type butt joint to install because installing space is limited at the whole replacement of broken pipe or pipeline.Can effectively improve installation efficiency, reduce installation difficulty.
The basic principle of the steel structure replacement pipe of band slip joint is to utilize the slip joint assembly can be in the left and right sides translation on one's body of fixed length steel-structure tube, and to reach under the condition that does not increase mounting distance, fixed length is installed the replacement pipeline.
The steel structure replacement pipe basic structure of band slip joint is made up of steel-structure tube (1), spacing steel ring one (2), O-ring seal one (3), bellmouth assembly one (4), block one (5), bolt (6), spacing steel ring two (7), O-ring seal two (8), bellmouth assembly two (9), block two (10); Spacing steel ring one (2) is set with into steel-structure tube (1) right ends with spacing steel ring two (7); Its position can move left and right; Bellmouth assembly one (4) is inserted in steel-structure tube (1) right ends respectively with bellmouth assembly two (9); Its position can move left and right; O-ring seal one (3) and O-ring seal two (8) are set between spacing steel ring one (2), spacing steel ring two (7) and bellmouth assembly one (4), the bellmouth assembly two (9); It is as a whole to utilize bolt (6) to connect, and block one (5) is welded on respectively on bellmouth assembly one (4) and the bellmouth assembly two (9) with block two (10), and its welding position is confirmed according to former pipeline slot length; Steel-structure tube (1) can be three-port structure or straight tube structure or is confirmed by design, bellmouth assembly one (4) and bellmouth assembly two (9) also can by design confirm to change into the socket assembly or hold, the socket assembly.
The present invention can be implemented under the installing space condition of limited preferably, through regulating slip joint bellmouth module position, accomplishes the installment work of pipeline, has improved installation efficiency, has reduced installation difficulty.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.Form by steel-structure tube (1), spacing steel ring one (2), O-ring seal one (3), bellmouth assembly one (4), block one (5), bolt (6), spacing steel ring two (7), O-ring seal two (8), bellmouth assembly two (9), block two (10).
Embodiment
In actual use; At first spacing steel ring one (2) is set with into steel-structure tube (1) right ends with spacing steel ring two (7); Pack into then O-ring seal one (3) and O-ring seal two (8), pack at last bellmouth assembly one (4) and bellmouth assembly two (9) lean on bolt (6) fixing.To be positioned over the replacement position with the steel structure replacement pipe of slip joint then; Unclamping bolt (6) release bellmouth assembly one (4) installs with bellmouth assembly two (9) and former pipeline socket; Outer O-ring seal one (3) and the O-ring seal two (8) of moving after accomplishing; Last outer spacing steel ring one (2) and the spacing steel ring two (7) of moving; The bolt (6) of screwing makes O-ring seal one (3) and O-ring seal two (8) distortion and steel-structure tube (1) surface produce fixedly slip joint assembly of frictional force through extruding force, and final the completion replaced piping erection.
Claims (4)
1. the steel structure replacement of band slip joint is managed; It is characterized in that: form by steel-structure tube (1), spacing steel ring one (2), O-ring seal one (3), bellmouth assembly one (4), block one (5), bolt (6), spacing steel ring two (7), O-ring seal two (8), bellmouth assembly two (9), block two (10); Spacing steel ring one (2) is set with into steel-structure tube (1) right ends with spacing steel ring two (7); Its position can move left and right; Bellmouth assembly one (4) is inserted in steel-structure tube (1) right ends respectively with bellmouth assembly two (9); Its position can move left and right; O-ring seal one (3) and O-ring seal two (8) are set between spacing steel ring one (2), spacing steel ring two (7) and bellmouth assembly one (4), the bellmouth assembly two (9), and it is as a whole to utilize bolt (6) to connect, and block one (5) and block two (10) are welded on respectively on bellmouth assembly one (4) and the bellmouth assembly two (9).
2. the steel structure replacement pipe of band slip joint as claimed in claim 1 is characterized in that: said block one (5) is confirmed according to former pipeline slot length with block two (10) its welding positions.
3. PCCP pipe coupling seal tightness test device as claimed in claim 1 is characterized in that: said steel-structure tube (1) can be three-port structure or straight tube structure or definite by design.
Bellmouth assembly one (4) and bellmouth assembly two (9) also can by design confirm to change into the socket assembly or hold, the socket assembly.
