Description

Seal cage is set to the pipeline compensator on inclined-plane
Technical field
The present invention relates to pipeline compensator technical field, especially a kind of Seal cage end face is set to the compensator of ramp structure.
Background technique
Generally all need to install and use compensation device in the pipeline of the industries such as electric power, oil, chemical industry, heating power, existing compensation device generally includes whirl compensator, sleeve expansion joint, spherical compensator etc., for compensating pipeline axial and radial displacement.Especially carry the pipeline of high temperature, high-pressure medium higher for the requirement of compensator, compensator not only will have enough displacement compensation amount, also will have the feature of favorable sealing property and long service life.
The Seal cage of existing whirl compensator, sleeve expansion joint, spherical compensator is all generally flat square structure, i.e. mutually vertical between adjacent two faces of Seal cage.Flange for stuffing box packing in press seal chamber is also conventional plane design, and namely by the stuffing box packing in Flange Plane press seal chamber, Flange Plane can decay with the increase of length gradually to stuffing box packing applied pressure.At present, the flat square structure of existing compensator Seal cage can cause the upper and lower Density inhomogeneity of stuffing box packing, causes the sealability of compensator to decline.After the work of compensator stamen pipe, compensator is easy to because packing seal is not tight and leaks, and causes decline the working life of compensator, the maintenance cost of adding users, sometimes even has to pipeline to stop production to change compensator, cause greater loss.
Summary of the invention
For the deficiency of above existing compensator Seal cage and stuffing box packing, the object of this invention is to provide the compensator that a kind of Seal cage end face is set to ramp structure, utilize the inclined-plane of Seal cage and put into the spacer ring of stuffing box packing, effectively can improve the uniformity of compensator stuffing box packing, improve sealing effect.
The object of the invention is by realize by the following technical solutions:
Seal cage is set to the pipeline compensator on inclined-plane, comprise compensator core pipe, outer sleeve and flange, described core pipe box is located in outer sleeve, outer sleeve and Flange joint, the internal surface of described outer sleeve is provided with annular stop circle, one end face of flange is provided with bulge loop, and the internal surface of the outer surface of described flange bulge loop and core pipe, position limit cycle and outer sleeve forms Seal cage;
The surface of described flange bulge loop is set to inclined-plane, and the internal surface of described outer sleeve position limit cycle is also set to inclined-plane, and two inclined-planes are symmetrically set and form two end faces of described Seal cage.
As the preferred technical solution of the present invention, the angle between the inclined-plane of described flange bulge loop and core tube outer surface is set to A angle, and A angle is less than 90 degree, and the inclined-plane of described outer sleeve position limit cycle is equal with A angle with the angle between core tube outer surface.
As the preferred technical solution of the present invention, described A angle is greater than 60 degree and is less than 80 degree.
As the preferred technical solution of the present invention, be provided with stuffing box packing in described Seal cage, the centre of stuffing box packing is provided with spacer ring.
As the preferred technical solution of the present invention, two end faces of described spacer ring are respectively equipped with V-shaped groove, and the angle of described V-shaped groove is set to C angle, and C angle is greater than 90 degree.
As the preferred technical solution of the present invention, described C angle is greater than 120 degree and is less than 150 degree.
The invention has the beneficial effects as follows: relative to prior art, the Seal cage end face of compensator is set to inclined-plane by the present invention, the filler seal face of flange is also set to ramp structure simultaneously, adds stuffing box packing to half in Seal cage, put into spacer ring, and then continue to add second half stuffing box packing; Effectively can improve the uniformity of stuffing box packing like this, thus improve the sealability of compensator.
The present invention utilizes the ramp structure of Seal cage and puts into the spacer ring of stuffing box packing, when compressing filler, filler is extruded to stamen tube outer surface, make the stuffing box packing density of stamen tube outer surface strengthen and more even, strengthen the sealing effect of compensator stuffing box packing, not only structure is simple, cost is lower, and convenient for installation and maintenance, and the working life of compensator improves more than 20%.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
