The assembling of composite expanded joint structure
Being installed as of composite expanded regulating device of the present invention, one end and the AA of A inner sleeve 2 of A pipeline 7 shrink oblique section 2A and weld, the AB of A inner sleeve 2 shrinks oblique section 2B end and holds by seal ring (the first seal ring 9A with the AA groove section 1F of A outer sleeve 1, second seal ring 9B, 3rd seal ring 9C) movable sealing connection, the AB groove section 1J of A outer sleeve 1 holds by seal ring (the 4th seal ring 9D, 5th seal ring 9E, 6th seal ring 9F) shrink oblique section 5A with the BA of B inner sleeve 5 and hold movable sealing to be connected, the BB of B inner sleeve 5 shrinks oblique section 5B end and holds by seal ring (the 7th seal ring 9G with the BA groove section 4F of B outer sleeve 4, 8th seal ring 9H, 9th seal ring 9I) movable sealing connection, the BB groove section 4J end of B outer sleeve 4 welds with the other end of B pipeline 8.
Shown in Figure 3, according to the installation of A outer sleeve 1, A inner sleeve 2, A guide rail slide block assembly 3, B outer sleeve 4, B inner sleeve 5, B guide rail slide block assembly 6 and seal ring.In the present invention, by organize that the series connection of single group expansion joint obtains more expansion joint device be called composite expanded joint.The composite expanded energy-conservation pipeline that is enough in turns round between less two pipelines (A pipeline 7 and B pipeline 8) of relative radian, and generally, shown in Figure 1A, A pipeline 7 applies composite expanded joint with the established angle β of B pipeline 85 degree ~ 70 degree time.When the established angle β of A pipeline 7 and B pipeline 8 is close to 5 degree, the joint number of the list group expansion joint of needs is at 13 ~ 20 joints.
In the present invention, no matter be apply singly to organize expansion joint, or composite expanded joint realizes the connection of two pipeline corners, the diameter of inside and outside sleeve and the diameter of pipeline match (pipe diameter is not less than 16 centimetres), can conveniently be welded as good.The length of inside and outside sleeve is relevant to the size of established angle β, and when established angle β is larger, the length of inside and outside sleeve is longer.Usually, as shown in Figure 2 C, the length of an outer sleeve is designated as L1 (unit, centimetre), and the length of an inner sleeve is designated as L2 (unit, centimetre), and when β=5 degree, 2.5≤L1+L2≤11; When β=85 degree, 25≤L1+L2≤50.
In order to meet the larger distance of stretch out and draw back between corner pipeline (A pipeline 7, B pipeline 8), the assembling that can arrange the inside and outside sleeve of multistage reaches, the composite expanded joint that namely multiple single group expansion joint is in series.Distance of stretch out and draw back in the present invention, refers to the distance of pipeline in pipe lengths along additionally arranging.
In the present invention, due to pipeline employing is mostly steel pipe, or ferro-aluminum skin, and therefore inside and outside sleeve, guide rail and slide block are selected the material identical with pipeline to process.Seal ring is plastic materials processing or is silicon rubber loop.
The expansion joint device of the present invention's design, the automatic-sealed being highly suitable for corner pipeline connects.Be more applicable for the pipeline corner used in each technical module of industrialized production microspheres with solid catalyzer as shown in Figure 1.The mixture of the uniform temperature of carrying in pipeline and the gas of pressure and material, in order to the automatic-sealed realizing corner connects, make use of pressure in pipeline when being obstructed in corner, the distortion of the relative movement of inside and outside sleeve is promoted by pressure, thus the slip of band movable slider on guide rail, and by being arranged on the nut at guide rail two ends to realize limiting of slip maximum position.In the present invention, the inside and outside sleeve of design and coordinating of guide rail slide block assembly are that the distortion under the pressure condition of pipeline self conveying connects to reach automatic-sealed.The relative movement of inside and outside sleeve is plastic deformation, advantageously in the connection of pipeline corner.
The present invention devise a kind of industrialized production microspheres with solid catalyzer with the expansion joint device that connects of pipeline enclosure, the technical problem being the pipeline how in pipeline corner and connecting to be solved, present invention employs the oblique section of contraction of inner sleeve and shrinking with the groove seal ring section of outer sleeve the technological means coordinated with the automatic-sealed of elongation process, thus reach the relative movement of corner pipeline, plastic deformation reaches self-sealing technique effect.
