Abstract
The utility model provides a pipe joint for maintaining a pipeline, comprising a first connecting ring, a second connecting ring and a connecting cover, wherein the outer surface of the first connecting ring is provided with screw thread, the inner diameter of the second connecting ring is matched with that of the first connecting ring, the outer surface of the second connecting ring is provided with a radial lug boss ring, the connecting cover is screwed at a connecting part between the first connecting ring and the second connecting ring, and the inner surface of the connecting cover is provided with a screw thread. The pipe joint adopts the first connecting ring and the second connecting ring, and a damaged part of a pipe fitting is replaced by the connecting cover, so that the undamaged part of the pipe fitting can be continuously used, and the pipe joint is relatively lower in operation cost and manufacture cost.
Description
Technical field
The utility model relates to a kind of pipe joint that pipeline is used that keeps in repair.
Background technique
Even if the fluid water that pipeline is carried pipeline is also had corrosive action, and the pipeline that is corroded is the local damage of pipe fitting mostly, be not that the integral body of pipe fitting is damaged.In the prior art, maintenance or replacing pipeline are closed the fluid of being carried usually, behind the fluid discharge pipe road in the wait pipeline; And then the pipe fitting of local damage repaired or replaced; And maintenance is the means that adopt welding, is about to the method sealing of the damaged position of pipe fitting with welding, and is well-known; Special-purpose equipment during welding needs, its cost is higher relatively; In addition, for the pipe fitting of local damage,, can reduce cost and save raw material like this as long as its damaged position reparation can be continued to use, so, the pipe fitting integral replacing that is local damage can be improved maintenance cost.
Summary of the invention
The task of the utility model provides the pipe joint that a kind of maintenance pipeline of using the mode of pipe reparation to solve the maintenance cost problem to the damaged position of pipe fitting is used.
The pipe joint that the maintenance pipeline that the utility model proposed is used comprises that outer surface is provided with threaded first connecting ring and is complementary with the first connecting ring internal diameter and outer surface is provided with radially second connecting ring of boss ring, and is screwed in first connecting ring and the second connecting ring junction and internal surface threaded connecting sleeve is set.
The internal surface of said first connecting ring and second connecting ring is respectively arranged with the circular groove that radially caves inward; The end that first connecting ring and second connecting ring engage is respectively arranged with the annular end slot that axially caves inward, and circular groove and annular end slot all are equipped with elastic seal ring.
The internal surface of said second connecting ring radially be provided with the bulge loop that is used to limit the position.
The lower end of said connecting sleeve is provided with the radial convex loop that extends radially inwardly and be complementary with radially boss annular shape on second connecting ring.
The pipe joint that the maintenance pipeline that the utility model proposed is used adopts first connecting ring and second connecting ring, and connecting sleeve substitutes the damaged position of pipe fitting, installs very convenient quick on the one hand; Can make pipe fitting not have the part of damage to continue to use; And its running cost and fabricating cost are all relatively low, on the other hand a plurality of pipe joints can be installed on a pipe fitting, so; No matter on a pipe fitting damaged position, several places is arranged, all can keep in repair through this pipe joint.
Description of drawings:
Accompanying drawing 1 is the embodiment's of pipe joint that uses of maintenance pipeline that the utility model proposes a cut-away section structural representation.
Embodiment:
Referring to Fig. 1, this figure provides the embodiment's of pipe joint that maintenance pipeline that the utility model proposes uses overall appearance structure.This pipe joint comprises first connecting ring 1, second connecting ring 2, and connecting sleeve 3.Wherein, the outer surface of first connecting ring 1 is provided with screw thread 11 and fin 12, and its internal surface is provided with the end that two circular grooves that radially cave inward, 13, the first connecting rings 1 engage with second connecting ring 2 and is provided with the annular end slot 14 that axially caves inward; Second connecting ring, 2 internal surfaces radially be provided with bulge loop 21 and two circular grooves that radially cave inward 23 that are used to limit the position; Its outer surface is provided with the end that radially boss ring 22, the second connecting rings 2 that extend radially outwardly engage with first connecting ring 1 and is provided with the annular end slot 24 that axially caves inward; The internal surface of connecting sleeve 3 is provided with internal thread; Be provided with the radial convex loop 31 that extends radially inwardly and be complementary with radially boss ring 22 shapes on second connecting ring 2 in its lower end; After connecting sleeve 3 is screwed on first connecting ring 1; And make radial convex loop 31 snap onto the radially bottom of boss ring 22, so that first connecting ring 1 and second connecting ring 2, and form an integral body between connecting sleeve 3 threes.In order to make this pipe joint can realize good sealing, between annular end slot 14 and 24, elastic seal ring 4 is installed, and in circular groove 13 and circular groove 23, elastic seal ring 5 is installed also.
Claims (6)
