Abstract
The utility model relates to a pipe connector characterized by comprising a pipe-shaped connecting body (3), wherein a flange connection disc (2) is arranged at the front end of the connecting body, and a flange compression disc (6) is arranged at the rear end thereof; a sealing piece and a holding piece are arranged in the inner cavity of the connecting body; the sealing piece comprises sealing rings (11.1, 11.2) and retainer rings (12, 12.1, 12.2) thereof arranged side by side or at intervals; the holding piece comprises pipe-shaped slips (9) and slip sleeves (8) arranged outside the slips; clamping teeth (9.1, 8.1) fitted with each other are respectively formed on the outer wall of the slips and the inner wall of the slip sleeves; the rear end of the slip sleeves is tightly compressed by the flange compression disc; and the flange compression disc is fixed with the rear end of the connecting body via an axial bolt (7). Accordingly, the pipe connector of the utility model has the advantages of simple and skillful structure, convenient and rapid operation and good leak-prevention effect; particularly, the pipe connector is capable of flexibly removing damaged pipes and leaving as much usable pipes as possible, thus guaranteeing the rapid and convenient repair work, saving the materials and greatly reducing the repair cost.
Description
Technical field
The utility model 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.
The model utility content
The purpose of this utility model is in order to solve the problems of the technologies described above, to propose a kind of pipe jointer, and 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 purpose of this utility model is 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 utility model 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 utility model: 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 utility model.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 utility model 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. 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 utility model 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.
