Abstract
A flange connection type rotary joint comprises a locking gland (1), a rotary bearing (2), a sealing ring (3), a rotary connection sleeve (4), a joint external connection screw (5), an annular groove (6), a rotary mandrel (7), an installation flange (8), a rotary shaft sealing ring (9) and a mandrel center hole (10). The rotary joint is characterized in that the lower end of the installation flange (8) and the lower end of the rotary mandrel (7) are provided with a rotary shaft (11), and the rotary mandrel (7) and the rotary shaft (11) are sealed through the rotary shaft sealing ring (9). According to the rotary joint, the installation flange and the rotary shaft are designed on the rotary mandrel for matching, and the rotary joint is fixed to the rotary shaft through a screw. The rotary mandrel and the rotary shaft are sealed through the rotary shaft sealing ring, and it is guaranteed that gas and liquid between the rotary mandrel and the rotary shaft can not leak.
Description
Technical field
The present invention relates to a kind of jointing, be especially applicable to the connecting structure easily got loose.
Background technique
Existing swivel joint, what mostly adopt is scyewed joint, and screw thread divides left-handed and dextrorotation.Be threaded when installing on the rotary shaft, running shaft sense of rotation must be contrary with the direction of screwed tight.Such running shaft can not get loose because of the rotating force of moment when rotated, if that consistent with the direction of screw-threaded coupling power of main shaft sense of rotation just there will be the phenomenon that swivel joint gets loose.But the running shaft existing rotating forward when rotated that normal conditions lower swivel is installed has reversion again, and the swivel joint of such scyewed joint just cannot be competent at a job.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of flange join type swivel joint, this joint adopts flange-type to install, and being connected on the rotary shaft by joint, solving the phenomenon that getting loose appears in running shaft swivel joint when needing clockwise and anticlockwise with many screws.
Technological scheme of the present invention is achieved in the following ways: a kind of flange join type swivel joint, by locking gland, swivel bearing, seal ring, rotate joint sleeve, the external screw of joint, circular groove, rotary core shaft, mounting flange, rotary shaft seal ring, mandrel center hole forms, described rotation joint sleeve is connected by swivel bearing with rotary core shaft, sealing both seal ring realizes, locking gland will rotate joint sleeve and rotary core shaft locking, rotary core shaft is designed with mounting flange, rotary shaft seal ring and mandrel center hole, it is characterized in that: described mounting flange be provided with running shaft with the lower end of rotary core shaft, sealing is realized by rotary shaft seal ring between rotary core shaft and running shaft.
The external screw of joint and circular groove is provided with in described rotation joint sleeve, the mandrel center hole of circular groove and rotary core shaft coordinates, gas or liquid are transported in the mandrel center hole of rotary core shaft by the external screw of joint, circular groove, then are transported in running shaft by mandrel.
Described mounting flange and running shaft are fixed by screw, make the leakage that there will not be gas and liquid between the two.
The present invention, is coordinated by mounting flange that live spindle designs and running shaft, swivel joint and running shaft is fixed with screw.By realizing sealing with rotary shaft seal ring between rotary core shaft and running shaft.Ensure the leakage that there will not be gas and liquid between the two.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is scheme of installation of the present invention.
Embodiment
Known by Fig. 1, a kind of flange join type swivel joint, by locking gland 1, swivel bearing 2, seal ring 3, rotation joint sleeve 4, the external screw 5 of joint, circular groove 6, rotary core shaft 7, mounting flange 8, forms with rotary shaft seal ring 9, mandrel center hole 10 and running shaft 11.Described rotation joint sleeve 4 and rotary core shaft 7 connect 2 by swivel bearing, the sealing both seal ring 3 realizes, and rotation joint sleeve 4 and rotary core shaft 7 are locked by locking gland 1, are unlikely to get loose in use; Rotary core shaft 7 is designed with mounting flange 8, with rotary shaft seal ring 9 and mandrel center hole 10.
Known by Fig. 2, realize by installing swivel bearing 2 connection of rolling between described rotation joint sleeve 4 and live spindle 5, seal ring 3 realizes sealing between the two.Rotate in joint sleeve 4 and be manufactured with the external screw 5 of joint and circular groove 6, the mandrel center hole 10 of circular groove 6 and rotary core shaft 7 coordinates.Gas or liquid are transported in the mandrel center hole 10 of rotary core shaft 7 by the external screw 5 of joint, circular groove 6, are transported in running shaft 11 by rotary core shaft 7.
Known by Fig. 2, the present invention, coordinated by the mounting flange 8 of design in rotary core shaft 7 and running shaft 11, the present invention will be revolved with screw and running shaft 11 is fixed.By realizing sealing with rotary shaft seal ring 9 between rotary core shaft 7 and running shaft 11.Ensure the leakage that there will not be gas and liquid between the two.
