Abstract
The invention relates to a pipeline connector. The pipeline connector is characterized in that a tubular connection body (3) is arranged, the front end of the tubular connection body is provided with a flange connection tray (2) while the rear end is provided with a flange pressure plate (6), the inner chamber of the connection body is internally provided with a sealing element that and a clasping element, wherein the sealing element consists of sealing rings (11.1, 11.2) and sealing ring retainer rings (12, 12.1, 12.2) arranged in parallel or at intervals, and the clasping element consists of a tubular slip (9) and a slip sleeve (8), the slip sleeve is sheathed outside the slip, the outer wall of the slip and the inner wall of the slip sleeve are respectively provided with chucking teeth (9.1, 8.1) matched with each other, the rear end of the slip sleeve is tightly pressed by the flange pressure plate, and the flange pressure plate and the rear end of the connection body are fixed by an axial bolt (7). The invention has advantages of simple and smart structure, quick and convenient operation and good leakage-proof effect; and particularly, by adopting the invention, broken pipelines can be removed flexibly, available pipelines can be reserved to the largest extent, the restoration work is simple and convenient, the materials can be saved, and the restoration cost can be reduced greatly.
Description
Technical field
The invention belongs to a kind of pipe rehabilitation technology, specifically is a kind of to submarine pipeline, and the recovery technique of extra large pipe particularly is to be used for the pipe jointer that repair couples together the pipe of the pipe that blocks and joint fast.
Background technique
Along with expanding economy, under water, the pipeline of submarine laying is more and more.Because relatively poor with the environment in seabed under water, or even abominable, cause very big difficulty for the reparation of pipeline.Therefore, how apace will be under water with guaranteeing both quality and quantity, the submarine pipeline reparation is a problem that becomes more and more important.For this reason, need to propose a kind of assembling pipe joint that is used for repairing fast submarine pipeline.
Summary of the invention
The objective of the invention is to propose a kind of pipe jointer in order to solve the problems of the technologies described above, this connector construction is simple, and is very easy to use, can rapidly the pipe that breaks be coupled together with normal pipe, and be connected firmly good airproof performance.
The objective of the invention is to be achieved through the following technical solutions: pipe jointer, it is characterized in that: be provided with the tubulose connecting body, the front end of this connecting body is provided with the flange land, and the rear end is provided with the flange platen, is provided with Sealing and holds part tightly in described connecting body inner chamber; Described Sealing by side by side or the seal ring and the backup ring of at interval discharging constitute, the described part of holding tightly is made of tubulose slips and slip sleeve, slip sleeve is located at the outside of slips, the outer wall of slips and the inwall of slip sleeve are respectively equipped with the chucking tooth of mutual coupling, the rear end of slip sleeve is compressed by described flange platen, and the rear end of flange screw dish and connecting body is fixed by axial bolts.
The present invention further improves and the additional project of enforcement is:
The inwall of described slips is provided with sealing gasket.
The front end of described slip sleeve is provided with the pin that compresses in order to top tight sealing circle and backup ring.
The wall of described connecting body is provided with liquid filling hole and pressure testing hole.
The use of connector of the present invention: when under water, submerged pipeline large size occurs and leak, and in the time of can not welding again, pipe leakage partly amputated, connect with connector of the present invention.The first step: the nothing that pipeline is remaining is leaked in the termination insertion connector of part; Second step: the nut of the flange platen at locking connecting body rear portion; The 3rd step: hold out against slip sleeve, make the slips locking pipe, will hold out against, tight a bolt simultaneously, make the seal ring dilatancy, thereby play the effect of closed conduit, blocking-up leakage in order to the pin that compresses of top tight sealing circle and backup ring; The 4th step: the flange land and the flange plate that is repaired the pipeline the other end of connector front end are coupled together; The 5th step: by liquid filling hole and pressure testing hole, connector inside is detected, detected the reparation of promptly having finished pipeline after qualified.
The present invention is owing to be provided with seal arrangement, enclasp device and flange land, and be arranged in the connecting body, so simple and ingenious structure, easy to operate quick, good leak-proof effect particularly can be removed bad pipeline neatly, keeps to greatest extent and can utilize pipeline, make repair not only fast and convenient but also save material, can reduce rehabilitation cost greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the enlarged view of local A among Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further: embodiment: referring to accompanying drawing, pipe jointer is provided with tubulose connecting body 3, and the front end of this connecting body is provided with flange land 2, the rear end is provided with flange platen 6, is provided with Sealing and holds part tightly in described connecting body inner chamber; Described Sealing is made of the seal ring 11.1,11.2 and the backup ring 12,12.1,12.2 of discharging at interval, the described part of holding tightly is made of tubulose slips 9 and slip sleeve 8, slip sleeve is located at the outside of slips, the outer wall of slips and the inwall of slip sleeve are respectively equipped with the chucking tooth 9.1,8.1 of mutual coupling, the rear end of slip sleeve is compressed by described flange platen, and the rear end of flange screw dish and connecting body is fixing by axial bolts 7.The inwall of described slips is provided with sealing gasket 9.2.The front end of described slip sleeve is provided with and compresses pin 10 in order to top tight sealing circle and backup ring.The wall of described connecting body is provided with liquid filling hole 4 and pressure testing hole 5.
Present embodiment is very good through trial effect.Statistics through 1 year, in the rehabilitation expense in 1 year of past submerged pipeline, a working hour expense will units up to a million, also want a large amount of new pipelines change leakage pipe; Adopt connector of the present invention to carry out after the reinstatement works, the internal segment saving working hour was taken nearly 500,000 yuan in 1 year, had also saved the pipeline of nearly km in addition.
