Abstract
The invention discloses a conical surface padding. The conical surface padding comprises a padding box body, a supporting ring, a pressing ring, a T-shaped outer ring, a front conical ring, a rear conical ring, an axial spring and a cylindrical pin, wherein the T-shaped outer ring is of a radial cut structure, the front conical ring and the rear conical ring are symmetrically sleeved with the T-shaped outer ring in a connected mode, and the front conical ring and the rear conical ring are each of a radial cut structure. When the front conical ring and the rear conical ring are connected in a sleeved mode, the cuts are arranged with a 120-degree included angle, the cylindrical pin is used for fixing and positioning, contained in the supporting ring and the pressing ring and placed in the padding box at last, and an axial spring is used for pre-tightening. The conical surface padding is simple in structure, is mainly used for piston rod sealing of a high-pressure compressor with the pressure difference larger than 10 MPa to 100 MPa, and has both the radial self-tightening effect and the axial self-tightening effect.
Description
Technical field
The present invention relates to piston rod packing field of sealing technology, particularly relate to a kind of conical surface filler.
Background technique
In order to packed-piston bar passes the gap at cylinder place, usually realize sealing with one group of stuffing box packing.Because the structure of flat pack is comparatively simple, manufacturing procedure is uncomplicated, then usually adopt flat pack to realize the sealing of piston rod in prior art.And under high-pressure situations, if still adopt flat pack, then because gas pressure is very high, and filler itself can not offset gas pressure effect, cause filler effect specific pressure on the piston rod excessive and unstable wear.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of conical surface filler, can solve the problems of the technologies described above completely.
The technological scheme solved the problems of the technologies described above is as follows:
A kind of conical surface filler, comprise filler box body, support ring, hold-down ring, T-shaped outer shroud, front conical ring, rear conical ring, axle spring and straight pin, described T-shaped outer shroud adopts the structure of radial slot, described front conical ring and rear conical ring symmetry are socketed in T-shaped outer shroud, and described front conical ring and rear conical ring adopt the structure of radial opening, and during socket, otch is mutually 120 °, use straight pin stationary positioned, and be contained in support ring and hold-down ring, be finally placed in stuffing box, with axle spring pretension.
The oil film wedge angle of 15 ° is processed in described front conical ring and the inner circle outer end of rear conical ring.
Structure of the present invention is simple, and be mainly used in the rod seal of pressure reduction more than the high pressure compressor of 10 ~ 100MPa, existing radial self-tightening effect, has again axial self-tightening effect.Seal element adopts the T-shaped outer shroud of a radial slot and the tapered collar composition of two radial openings, front conical ring and rear conical ring are enclosed within T-shaped outer shroud symmetrically, during installation, otch is mutually 120 °, fix with locating stud, and be contained in inside support ring and hold-down ring, finally put into stuffing box, in stuffing box, be provided with axle spring, its effect makes seal ring produce a pretightening force to piston rod, to make cause initial sealing during driving.When gas pressure to act axially on the end face of hold-down ring from the right, resolve into a radial partial pressure by the conical surface, this power makes seal ring hold tightly on the piston rod.
In order to ensure the rubbing surface of the seal ring of lubricant oil wedging in the running, alleviating friction, improving sealability, being processed into the oil film wedge angle of 15 ° in the inner circle outer end of tapered collar.During installation, there is directivity at oil film wedge angle, should at the low voltage terminal of stuffing box.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure, 1 is support ring, and 2 is hold-down ring, and 3 is T-shaped outer shroud, and 4 is front conical ring, and 5 is rear conical ring, and 6 is axle spring, and 7 is straight pin, and 8 is filler box body.
Embodiment
A kind of conical surface filler as shown in Figure 1, comprise filler box body 8, support ring 1, hold-down ring 2, T-shaped outer shroud 3, front conical ring 4, rear conical ring 5, axle spring 6 and straight pin 7, described T-shaped outer shroud 3 adopts the structure of radial slot, described front conical ring 4 and rear conical ring 5 symmetry are socketed in T-shaped outer shroud 3, described front conical ring 4 and rear conical ring 5 adopt the structure of radial opening, during socket, otch is mutually 120 °, by straight pin 7 stationary positioned, and be contained in support ring 1 and hold-down ring 2 li, finally be placed in filler box body 8, with axle spring 6 pretension.The oil film wedge angle of 15 ° is processed in described front conical ring 4 and the inner circle outer end of rear conical ring 5.
Structure of the present invention is simple, and be mainly used in the rod seal of pressure reduction more than the high pressure compressor of 10 ~ 100MPa, existing radial self-tightening effect, has again axial self-tightening effect.Seal element adopts the T-shaped outer shroud of a radial slot and the tapered collar composition of two radial openings, front conical ring and rear conical ring are enclosed within T-shaped outer shroud symmetrically, during installation, otch is mutually 120 °, fix with locating stud, and be contained in inside support ring and hold-down ring, finally put into stuffing box, in stuffing box, be provided with axle spring, its effect makes seal ring produce a pretightening force to piston rod, to make cause initial sealing during driving.When gas pressure to act axially on the end face of hold-down ring from the right, resolve into a radial partial pressure by the conical surface, this power makes seal ring hold tightly on the piston rod.
In order to ensure the rubbing surface of the seal ring of lubricant oil wedging in the running, alleviating friction, improving sealability, being processed into the oil film wedge angle of 15 ° in the inner circle outer end of tapered collar.During installation, there is directivity at oil film wedge angle, should at the low voltage terminal of stuffing box.
