Abstract
The invention discloses a spherical-hinge high-temperature pressure-bearing liquid conveying pipeline connecting joint which is used for efficiently and safely conveying liquid. The pipeline connecting joint comprises a swinging ball, a sealing fixing seat, a guide connecting sleeve, a ball pressure ring, a pressure spring and a connecting bolt and nut, the swinging ball is connected and mounted inside the sealing fixing seat and the ball pressure ring, the ball pressure ring slides in the guide connecting sleeve and contacts with the pressure spring in the guide connecting sleeve, the swinging ball is fastened by the sealing fixing seat and the ball pressure ring under the action of the pressure spring, and the sealing fixing seat is integrally connected with the guide connecting sleeve through the connecting bolt and nut. The spherical-hinge high-temperature pressure-bearing liquid conveying pipeline connecting joint is unique in softness and flexibility, convenient to use, disassemble and assemble, reliable in connection, resistant to pressure, fine in sealing performance and wide in application range.
Description
Technical field
The present invention relates to the connection set of liquid conducting pipes, particularly a kind of ball pivot high-temperature bearing liquid conducting pipes connects joint.
Background technique
Some conveying high temperature have the requirements for pipes of press liquid to bend, and the general corrugated flexible hose that uses realizes at present.But two problems has in use appearred in corrugated flexible hose, one has been Security, and corrugated flexible hose, due to reasons in structure, is very easy to occur crackle, there will be potential safety hazard for there being the conveying of super pressure-high temperature liquid; Another needs periodic replacement, changes and take the production work time, have a strong impact on production.Therefore adopt connecting tube joint to be applied to high-temperature bearing Liquid transfer and become a kind of optimal selection.Because high temperature has in press liquid course of conveying, in pipeline, there is certain pressure, be transferred liquid and the most easily reveal at the hard sealing station in conveyance conduit connection joint.Research finds, the wear rate of the hard sealing station in conveyance conduit connection joint is 50 times of straight tube position, and joint very easily metal fatigue occurs in addition.Therefore it is solve fluid leakage and the key improving transfer efficiency that pipeline reasonable in design connects joint.
Summary of the invention
The invention provides a kind of ball pivot high-temperature bearing liquid conducting pipes and connect joint, for carrying liquid efficiently and safely.
A kind of ball pivot high-temperature bearing liquid conducting pipes provided by the invention connects joint and comprises: swing ball, sealing fixed base, guiding connecting sleeve, ball hold-down ring, holddown spring, connecting bolt and nut, described swing ball tipping is in the inside at sealing fixed base and ball hold-down ring, ball hold-down ring is sliding mode in guiding connecting sleeve, ball hold-down ring contacts holddown spring in guiding connecting sleeve, under holddown spring effect, sealing fixed base and the fastening of ball hold-down ring swing ball, and sealing fixed base and guiding connecting sleeve adopt connecting bolt and nut to link together.
Between described sealing fixed base and guiding connecting sleeve, seal element is set.
The material of described ball hold-down ring is metallic material, or nonmetallic material, or metal and nonmetallic composite material.
Described swing ball, sealing fixed base and ball hold-down ring surface all apply the coating of same expansion coefficient material.
The present invention's its significant beneficial effect compared with existing same device technology is embodied in:
1. the structure that the present invention adopts sealing fixed base, ball hold-down ring links closely mutually, can ensure under sealing fixed base, the fixed prerequisite of ball hold-down ring, swinging ball not only can 360 degree of rotation, and pitching up and down can wave each 15 degree, pipe joint can be straight coupling, tee union, cross fitting, 90 degree of elbows and one eighth bend, shows unique characteristics in flexibility, flexibility.
2. delivery pipe provided by the invention connect joint dismounting convenient, connect reliable, withstand voltage, good airproof performance, applied widely.
