Description
【Technical field】
The utility model relates to conduit coupling field more particularly to a kind of conduit couplings that can improve sealing performance.
【Background technique】
Conduit coupling uses pipeline reliable as the connection accessory in copper pipe Pipe installing, connection structure mode
Property has decisive role.Conduit coupling is divided into threaded connector, welded connections, card pressure connector, cutting ferrule by connection type
Connector, flange connector, wherein welded connections is the safest reliable, but complex process, processing request are high, flange connector
Suitable for large-scale pipeline, card pressure connector needs professional tool to be installed, threaded connector and cutting ferrule connector connection type
It is the most simple and practical, but cutting ferrule connecting-piece structure is complicated, and threaded connector leakproofness is poor.It is carried out herein for threaded connector
It improves.
【Summary of the invention】
In view of above-mentioned technical problem, the utility model proposes a kind of conduit couplings that can improve sealing performance, existing
It is improved on the basis of threaded connector, adds sealing ring, further increase the leakproofness of threaded connector.
To reach above-mentioned technical effect, the utility model uses following scheme：
A kind of conduit coupling that can improve sealing performance, including basic tube body and connection pipe body, the basic tube body
Outer diameter is big compared to the outer diameter of the connection pipe body, and annular groove is provided on the basic tube body, and the annular groove internal diameter is big
Body is consistent with the connection pipe body outer diameter, and the annular groove opening direction is identical as the connection pipe body direction, the annular
Sealing ring is set in groove.
More preferably, be provided with limiting groove in the annular groove, the sealing ring be placed on just the limiting groove with
In annular groove.
More preferably, annular further groove is provided in the connection pipe body, it is recessed that the annular further groove is located at the annular
In slot, the annular further groove is substantially concordant far from connection pipe body side and the annular groove bottom, the sealing ring
Cross section is L shape.
More preferably, nut is fixedly connected with outside the basic tube body.
More preferably, screw thread setting is in the connection pipe body outer surface, and the screw thread is relative to the connection pipe body protrusion.
Compared with prior art, the beneficial effects of the utility model are：Due to adding sealing ring, pipeline company is substantially increased
The leakproofness of fitting is in close contact pipeline and the screw thread of connection pipe body, further improves close since sealing ring has elasticity
