Abstract
The utility model provides a sealing pipe fitting joint which comprises a tee body. External pipes are fixedly connected with outer ends of two coaxial pipes of the tee body, the pipe diameter of each external pipe is larger than that of the tee body, bosses are arranged at joints of the external pipes and the tee body, annular grooves which are coaxial with the external pipes are arranged on the bosses, annular sealing rubber cushions are arranged in the annular grooves, and axial spiral ribs are arranged on inner walls of the two coaxial pipes of the tee body. The sealing pipe fitting joint has the advantages of good sealing performance and capability of reducing noise generated during flowing of liquid in the pipes.
Description
Technical field
The utility model belongs to the pipe fitting field that nuclear industry is used, and especially relates to a kind of sealed pipe fittings joint.
Background technique
Pipe fitting is the part that pipe is connected into pipeline.Can be divided into socket fitting, threaded fitting, flanged fitting and weld-end fittings four classes according to joining method.The multiplex material identical with pipe made.Elbow (ell), flange, three-way pipe, four-way pipe (crosshead) and reducer (CONCENTRIC REDUCER) etc. are arranged.
In the pipe fitting that nuclear industry is used, sealing must be guaranteed, the generation of Leakage prevention event.Simultaneously, because the pipeline use amount is larger, when liquid in pipe flowed, mobile sound was also larger, and when having pipe joint to have leakage phenomenon to occur, affected by noise being not easy found easily.
Summary of the invention
The purpose of this utility model provides a kind of sealed pipe fittings joint, has better sealing, can reduce noise simultaneously.
The technical solution of the utility model is:
A kind of sealed pipe fittings joint, comprise the three-way pipe body, the affixed externally connected pipe in two pipe outer ends of described three-way pipe body concentric, the externally connected pipe caliber is greater than the caliber of three-way pipe body, the joint of externally connected pipe and three-way pipe body is provided with boss, described boss is provided with the annular groove with the externally connected pipe concentric, is provided with the ring packing rubber cushion in this annular groove.
Described boss is provided with the ring packing rubber cushion with the externally connected pipe concentric.
The inwall of two pipes of described three-way pipe body concentric is provided with axial spiral bar.
Advantage and the good effect that the utlity model has are: arrange on the boss ring packing rubber cushion is set in annular groove and the groove, cooperate the ring packing rubber cushion that arranges on the boss, play the effect of secondary seal, sealability is higher; The spiral bar that arranges on the inwall can prevent from producing when liquid in pipe from flowing noise.
