Abstract
The utility model relates to a rotary joint which is mainly used for a urea granulator and the chemical industry. A main shaft is connected with a rotary core. The utility model is characterized in that an upper and a lower conical discs arranged on the rotary core carries out simultaneous movement following the main shaft; sealed conical rings matched with the upper and the lower conical discs can move towards the opposite direction under the action of a spring along a shaft line, and can not form circumference rotation; the rotary core forms the simultaneous movement following the main shaft, and the upper and the lower conical discs on the rotary core form rotary friction sealing with the sealed conical rings. The utility model has the advantages that the rotary joint can be ensured to work in the mode of high-speed rotation, and the high-speed rotary friction sealing is realized.
Description
The bright genus swivel joint of the present invention is made the field, is mainly used in urea granulator and chemical industry.
Background technique of the present invention: existing swivel joint, because its structural design is satisfied with the technological requirement that the normal pressure and temperature general fluid is passed through, and to high temperature, high speed and have the fluid chemical industry that freezes, it is powerless then to seem, and can't use.
Purpose of design of the present invention: avoid the deficiency in the background technique, design a kind of can be at high temperature, at a high speed and fluid freeze under the condition swivel joint of normal boot-strap work.
Design proposal of the present invention: 1, the spinning solution of swivel joint, main shaft connects with the commentaries on classics core, be positioned at the upper and lower awl dish that changes on the core and be synchronized with the movement with main shaft together with changeing core, the sealing conical ring that is sealed and matched with upper and lower awl dish can only move in the other direction and can not do the circumference rotation at the effect lower edge of spring axis.Change core and be synchronized with the movement with main shaft, upper and lower two the awl dishes that change on the core are the spin friction sealing with the sealing conical ring.2, swivel joint, changeing core (1) connects with the main shaft spindle nose, epicone dish (2) combines as a whole with commentaries on classics core (1), during main axis rotation, changeing core (1) is synchronized with the movement with main shaft, change core (1) two awl dishes and sealing conical ring (3 up and down, 15) spin friction sealing, sealing conical ring (3,15) by the elastic force of spring (9) with change core (1) conical surface, epicone dish (2) conical surface fits tightly, axial keyway on spring seat (7) cylindrical can only move axially under the effect that is fixed on the spring seat spline pin (8) on the housing (6) and can not rotate, sealing conical ring (3,15) use conical ring spline pin (4 in the positioning hole on the end face, 14) with its limit to, spline pin (4,14) the other end is inserted in the spring seat (7) and housing (6) of state of rest, so two seal rings (3 about when changeing core (1) rotation, 15) can only lean on the work of spring (9) as moving along axis and can not making circumference and rotate in the other direction, sealing conical ring (3,15) the ring-like chamfering of outer rim makes O RunddichtringO (5,13) tension force by spring (9) makes the distortion of O type rubber section be close to forming on the inwall of housing (6) partially sealed, liquid enters housing (6) through the charging bend pipe, enter in (1) through changeing several waist-shaped holes of core (1) middle part, deadweight is discharged by liquation again.The face that changes upper and lower two awl dishes of core (1) is the conical surface or sphere, the sealing conical ring that is complementary with it be shaped as tapered collar or spill sphere ring.
The present invention compares with background technique: the one, change the core design of two awl dishes and seal ring spin friction sealing configuration up and down, and not only guarantee the high speed rotating work of swivel joint, and realized the high speed rotary grinding sealing; The 2nd, axial keyway can only move axially under the effect that is fixed on the spring seat spline pin on the housing and the structural design that can not rotate on the spring seat cylindrical, lay respectively in the sealing conical ring end face positioning hole with conical ring spline pin two ends and the spring seat of static shape, the structural design in the housing, realized when changeing the core rotation, the effect that can only lean on spring of two sealing conical rings is moved in the other direction and can not be made circumference and rotate along axis up and down, guarantees the reliable sealing performance of O RunddichtringO.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment 1: swivel joint; the inner cone that changes core (1) connects with the standard industry tapering with tablet machine main shaft spindle nose; screw (12); plain cushion (10) and spring washer (11) will change core (1) and combine as a whole with the tablet machine main shaft; epicone dish (2) combines as a whole by being threaded and changeing core (1); when the tablet machine main axis rotation; changeing core (1) is synchronized with the movement with main shaft; change core (1) two awl dishes and sealing conical ring (3 up and down; 15) spin friction sealing; sealing conical ring (3; 15) by the elastic force of spring (9) with change core (1) conical surface; epicone dish (2) conical surface fits tightly; axial keyway on spring seat (7) cylindrical can only move axially under the effect that is fixed on the spring seat spline pin (8) on the housing (6) and can not rotate; sealing conical ring (3; 15) use conical ring spline pin (4 in the positioning hole on the end face; 14) with its limit to; spline pin (4; 14) the other end is inserted in the spring seat (7) and housing (6) of state of rest; so two seal rings (3 about when changeing core (1) rotation; 15) can only lean on the work of spring (9) as moving along axis and can not making circumference and rotate in the other direction; sealing conical ring (3; 15) the ring-like chamfering of outer rim makes O RunddichtringO (5; 13) tension force by spring (9) makes the distortion of O type rubber section be close to forming on the inwall of housing (6) partially sealed; fused solution enters housing (6) through the charging bend pipe; enter in (1) through changeing several waist-shaped holes of core (1) middle part again, reenter prilling spry certainly by liquation.The sidepiece of swivel joint has intake port, change core (1) middle part has several waist-shaped holes and communicates with the central well that changes core.
Embodiment 2: on embodiment's basis, the face that changes upper and lower two awl dishes of core (1) is the conical surface or sphere, the sealing conical ring that is complementary with it be shaped as tapered collar or spill sphere ring.
