Abstract
The invention relates to an ultrahigh-pressure omnidirectional dynamic joint which comprises a rotating valve body and a rotating shaft assembly. The rotating valve body is in an angular structure, and hollow cavities at both ends are respectively provided with communication holes; a rotating shaft in the rotating shaft assembly is provided with through holes; the front end of the rotating shaft is sleeved by an O-shaped ring, a bearing shell, a gasket, a guide ring, a pressure ring and another O-shaped ring, and the rear end of the rotating shaft is sleeved by a bearing and a locking nut to form the rotating shaft assembly; a series of parts forming the rotating shaft assembly are pressed in the hollow cavities of the rotating valve body by the locking nut which is connected with the inside thread of the rotating valve body so as to fix the sleeved parts, and a threaded plug and a threaded sleeve is connected with an external pipeline to form the ultrahigh-pressure omnidirectional dynamic joint. The invention achieves the ultrahigh pressure sealing effect over 300 MPa under an omnidirectional dynamic rotating condition, can randomly adjust a rotating angle and has the advantages of flexible rotation, reliable structure and long service life.
Description
Technical field
The present invention relates to the joint that fluid pipeline connects, the pipeline that is mainly used in high-pressure water cutting machine connects.Can do the arbitrarily angled rotation on two mutual vertical axis, guarantee that the fluid of conveying more than 300Mpa do not revealed and 360 ° of dynamic joints of ultrahigh pressure of flexible movements.
Background technique
The water jet that the high-pressure water cutting machine cutting head forms is along in the pattern cut process, and the position of cutting head is subjected to displacement constantly, and the conduit pipe that is connected with cutting head is also along with moving.Because of conduit pipe is in the hyperbaric environment, so must adopt withstand voltage metal pipe, though such tubing can bear high pressure, the rigidity of tubing own is very strong, and the displacement generation reaction force to cutting head influences the displacement of cutting head and final cutting effect.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of good seal performance, carries super high pressure fluid not leak under ultrahigh pressure rotation situation, can arbitrarily angled rotation and reliable in structure, and 360 ° of dynamic joints of the ultrahigh pressure of long service life.
The technological scheme that adopts is:
360 ° of dynamic joints of ultrahigh pressure comprise rotary valve, rotating shaft assembly.Rotary valve is an angular structure, be provided with intercommunicating pore in the cavity of two ends, running shaft in the rotating shaft assembly has through hole, running shaft front end suit O type circle, bearing housing, packing ring, lead ring, pressure ring, O type circle, the running shaft rear end is set with bearing, locking nut, constitute rotating shaft assembly, a series of parts that will constitute rotating shaft assembly with locking nut are pressed in the cavity of rotary valve, and are connected with the rotary valve internal thread its suit part is fixed.Be connected with exterior tubing by plug screw, swivel nut, constitute 360 ° of dynamic joints of ultrahigh pressure.
The present invention reaches the above superhigh pressure sealing effect of 300Mpa under 360 ° of dynamic rotating conditions, can regulate angle of swing arbitrarily, and the rotation flexible structure is reliable, has the advantage of long service life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 constitutes component assembling schematic representation of the present invention.
Embodiment
360 ° of dynamic joints of ultrahigh pressure comprise rotary valve 1, rotating shaft assembly 2.Rotary valve 1 is an angular structure, is provided with intercommunicating pore 11 in the cavity of two ends, and the running shaft 8 in the rotating shaft assembly 2 has through hole 15, and running shaft 8 front end sleeves are equipped with O type circle 14, bearing housing 7, packing ring 13, lead ring 12, pressure ring 9, O type circle 10.Running shaft 8 rear ends are set with bearing 6, locking nut 5, constitute rotating shaft assembly 2.A series of parts that will constitute on the rotating shaft assembly 2 with locking nut 5 are pressed in the cavity of rotary valve 1, and are connected with rotary valve 1 internal thread its suit part is fixed.Be connected with exterior tubing by plug screw 4, swivel nut 3, constitute 360 ° of dynamic joints of ultrahigh pressure.
After this dynamic joint bears hydrodynamic pressure, pressure acts on O type circle 10, O type circle promotes pressure ring 9, pressure ring 9 is introduced lead ring 12, pressure ring 9 expands like this, make to form sealing between rotary valve 1 and the running shaft 8, the very low bearing of friction factor 6 is housed between running shaft 8 and the locking nut 5, running shaft still can arbitrarily angledly be rotated freely after bearing pressure.
