Abstract
The utility model relates to a disk-shaped pipeline expansion piece and belongs to the field of pipeline delivery. An inner expansion tube and an outer expansion tube are sheathed with each other, the outer surface of the inner expansion tube at a sheathed end is provided with an outer ring, the inner surface of the outer expansion tube is provided with an inner ring and the outer ring is lapped with the inner ring. The outer ends of the inner expansion tube and the outer expansion tube are respectively provided with an end ear. Two ends of a disk sleeve are respectively fixedly connected with the end ears at two ends. Delivery pipes at two ends of the inner expansion tube and the outer expansion tube are respectively provided with a separate type movable clamping base. The expansion piece can be telescopic randomly under a temperature difference and a rubber disk sleeve can play a role of sealing. The cost is low and the installation is convenient.
Description
One, technical field
The utility model relates to a kind of dish-shaped pipeline extension device, belongs to the line transportation field.
Two, background technique
The fast development of Modern China economic society, science and technology is used timely and effectively in every field.Fast development along with modern industry.Especially increasingly sharpening of the critical role of heavy industry in national economy, to oil, the dependence of water etc. is strong day by day, and pipeline logistics becomes the realistic problem that needs to be resolved hurrily.At present, be used for its inner and outer pipe place of relatively moving of logistics pipeline expansion bend and realize sealing, utilize guide rod to realize telescopic moving, the sealing of movable part is poor, easily leaks, and complex structure is not easy to site operation, installation.
Three, summary of the invention
The purpose of this utility model is to provide and is difficult in a kind of pipeline logistics process leaking, and is simple in structure, is convenient to the dish-shaped pipeline extension device of site operation, installation.
Technical solution: telescopic pipe and outer telescopic pipe socket in the utility model, the interior telescopic pipe outer surface of socket end is provided with outer shroud, outer telescopic pipe internal surface is provided with interior ring, outer shroud and interior ring overlap joint, interior telescopic pipe is respectively equipped with the end ear with outer telescopic pipe outer end, fixedlying connected with two ends end ear respectively in dish cover two ends, is positioned on the delivery pipe at telescopic pipe, outer telescopic pipe two ends to be respectively equipped with the removable clamping seats of separated type.
The removable clamping seats of separated type is two semicircular rings, and its two ends are connected by bolt, and the semicircular rings lower end is welded with supporting foot, and supporting foot can move in guide rail.
The dish cover adopts rubber dish cover.
The utility model is owing to be provided with the removable clamping seats of separated type at delivery pipe, delivery pipe can be in guide rail the freedom of movement moving structure simple, be convenient to site operation, install, this practicality is newly at interior telescopic pipe, rubber dish cover is equipped with at outer telescopic pipe two ends, be implemented in the fixed end sealing, be difficult in the pipeline logistics process leaking, pipeline will inevitably cause flexible owing to the temperature difference when remote the conveying, in, contraction when the nested special construction of outer telescopic pipe can make temperature reduce can not produce the disconnection of joint, the removable clamping seats of separated type can move forward when temperature raises, inside and outside telescopic pipe is moved forward, maximum elongation amount when temperature raises is exactly the length of every inside and outside telescopic pipe, thereby pipeline is normally extended, and dieback can not occur.So just can both oil transportations normally when the temperature difference is arranged, can make pipeline flexible again.Such advantage is exactly:
1, can stretch arbitrarily during the temperature difference.
2, the nestable effect that can play sealing of rubber.
3, at the bottom of the cost, easy for installation.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Five, embodiment
Telescopic pipe 2 and outer telescopic pipe 3 sockets in the utility model, interior telescopic pipe 2 outer surfaces of socket end are provided with outer shroud, outer telescopic pipe 3 internal surfaces are provided with interior ring, outer shroud and interior ring overlap joint, interior telescopic pipe 2 is respectively equipped with end ear 7 with outer telescopic pipe 3 outer ends, the rubber dish overlap 1 two ends respectively with the end ear 7 by last annular gasket 9, tight screw 8 is fixedly connected, be positioned at telescopic pipe 2, be respectively equipped with the removable clamping seats 4 of separated type on the delivery pipe 5 at outer telescopic pipe 3 two ends, the removable clamping seats 4 of separated type is two semicircular rings, its two ends are connected by bolt, the semicircular rings lower end is welded with supporting foot, and supporting foot can move in guide rail 6.
Telescopic pipe 2 and outer telescopic pipe 3 nested installations in the utility model, the removable clamping seats 4 of separated type is fixed with pipeline, telescopic pipe 2, outer telescopic pipe 3 and welding in delivery pipe 5 is packed into.The slide rail of the removable clamping seats 4 of separated type uses the lower margin screw in the cement melt pit.The removable folder 4 tight seats of separated type are moved in guide rail 6, and then telescopic pipe 2 move in driving with outer telescopic pipe 3.
