Abstract
The utility model discloses a high temperature oil seal for a high temperature medium conveying pipeline. The high temperature oil seal comprises a hot air pipeline, a raw material filling pipe is connected to the lateral wall of the hot air pipeline, a static ring is fixed to the raw material filling pipe, an end cover is fixed outside the static ring, a rotating shaft is arranged in the static ring, a spherical dynamic ring is fixed to the rotating shaft, a spherical concave face matched with the spherical dynamic ring is formed in the inner wall of the static ring, the spherical dynamic ring is sleeved with a floating static ring, a vertical through hole matched with the rotating shaft is formed in the floating static ring, a spherical concave ring matched with the spherical dynamic ring is formed in the lower end of the floating static ring, a high temperature seal ring is arranged between the static ring and the floating static ring, a spring adjusting bolt is fixed to the end cover, the lower end of the spring adjusting bolt is connected with a spring, and the lower end of the spring is pressed to the floating static ring. A floating ball structure is adopted in the high temperature oil seal for the high temperature medium conveying pipeline, a seal face is double spheres, eccentricity and rotation of the shaft can be ensured, the ball is made of a metal material, and the high temperature oil seal is assembled in a subdivision mode, thereby being resistant to high temperature and convenient to mount.
Description
Technical field
The utility model relates to high temperature media transportation art, specifically belongs to high temperature media conveyance conduit high temperature oil sealing.
Background technique
The pipeline of carrying high temperature media (liquid or gas), for the flow of control media, is generally equipped with a large amount of regulating valves, and the shaft extension of linkage valve goes out pipeline one end and is fixed on bearing, by linking mechanism, rotates.The other end stretches in pipeline, is fixed on valve, and the valve that rotarily drives by axle rotates.The axle of rotation and the gap between hot air duct need sealing, and current encapsulating method has: one, packing seal; Two, rubber and plastic elastic packing; Three, mechanical seal.Its using effect is all undesirable, and packing seal elastic compensating is poor, after wearing and tearing or eccentric shaft, produces gap and causes revealing; Rubber seal good springiness, but the normal serviceability temperature of macromolecular material is all below 320 ℃, is difficult to guarantee can use for a long time 300 ℃ of left and right, generally all at three months, with regard to aging, hardens; Mechanical seal can not solve the eccentricity issues of axle.
Model utility content
The purpose of this utility model is to provide a kind of high temperature media conveyance conduit high temperature oil sealing, adopts floating ball structure, and sealing surface is two spheres, can guarantee bias, the rotation of axle, and ball is metallic material, and is subdivision assembling type, Gu high temperature resistant, easy for installation.
The technical solution of the utility model is as follows:
High temperature media conveyance conduit high temperature oil sealing, include hot air duct, on hot air duct sidewall, be connected with raw material and fill out pipe, raw material is filled out and on pipe, is fixed with stationary ring, stationary ring is fixed with end cap outward, in stationary ring, be provided with rotating shaft, in rotating shaft, be fixed with spherical rotating ring, stationary ring inwall has the spherical concave surface matching with spherical rotating ring, on spherical rotating ring, be set with unsteady stationary ring, in unsteady stationary ring, have the vertical perforation matching with rotating shaft, unsteady stationary ring lower end has the ball recess matching with spherical rotating ring, between described stationary ring and unsteady stationary ring, be provided with high-temperature seal ring, on described end cap, be fixed with spring adjusting bolt, the lower end of spring adjusting bolt is connected with spring, the lower end of spring is pressed on floats on stationary ring.
On described unsteady stationary ring, be fixed with prevention rotary block, stop rotary block corresponding with the block on end cap.
Between described stationary ring and end cap, by screw, be fixedly connected with.
On hot air duct 1 of the present utility model, be welded with former loading pipe 2, on former loading pipe 2, use fixedly stationary ring 4 of bolt 3, the bottom surface of stationary ring 4 is processed with spherical concave surface, coordinate with spherical rotating ring 5, the inner peripheral surface of stationary ring 4 and high-temperature seal ring 8 combinations, high-temperature seal ring 8 is fixed by the groove floating on stationary ring 7, and moves up and down with unsteady stationary ring 7.The stationary ring 7 that floats is sphere-contact with the top of annular rotating ring 5, and the stationary ring 7 that floats floats by spring adjusting bolt 10 and the spring 9 being fixed on end cap 13, and pressurization compensation, makes two spheres up and down of spherical rotating ring 5 produce certain pressure; Spherical rotating ring 5 adopts split type, by moving, is fixed on axle 6, and with axle 6 rotations, if axle 6 bias, sphere can move thereupon, but can not produce gap, reaches sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
