Abstract

The utility model discloses a high-pressure pipeline compensator. The high-pressure pipeline compensator comprises an inserted pipe (1), an external casing (2) and a connecting rod (3) connected with the inserted pipe (1) and the external casing (2), and is characterized in that quick connectors (4) are arranged at the outer ends of the inserted pipe and the external casing; a seal packing cavity is arranged at the joint between the inserted pipe and the external casing and filled with flexible graphite seal packing (5); graphite packing filling holes are formed in the external wall of the seal packing cavity; and bolts (6) are arranged in the filling holes. The high-pressure pipeline compensator is connected with a pipeline by the quick connectors at the outer ends, and is convenient and quick to install; the flexible graphite seal packing is good in sealability; and the service life is long.

Description

A kind of pressure duct expansion bend
One, technical field:
The utility model relates to a kind of pipeline expansion bend, particularly pressure duct expansion bend.
Two, background technique:
In known technology, be used for the pressure duct expansion bend, comprise interpolation pipe and outer sleeve, the connecting rod that connects interpolation pipe and outer sleeve is arranged, at interpolation pipe and outer sleeve jointing place packing_seal is set, the outer end and the pipeline of interpolation pipe and outer sleeve are welded to connect.The deficiency of this structure is need be welded to connect expansion bend and pipeline at work progress, operation inconvenience; Another deficiency is at interpolation pipe and outer sleeve jointing place packing_seal to be set, in the poorly sealed easy leakage of pipeline expansion bend in service.
Three, summary of the invention:
The purpose of the utility model is to provide a kind of pressure duct expansion bend, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of pressure duct expansion bend; It comprises interpolation pipe (1) and outer sleeve (2), has the connecting rod (3) of connection interpolation pipe (1) and outer sleeve (2), and its special way is to be provided with in the outer end of interpolation pipe and outer sleeve rapid pipe joint (4); At interpolation pipe and outer sleeve jointing place the stuffing box packing chamber is set; Have the Expanded graphite stuffing box packing (5) of injection in the stuffing box packing chamber, have the graphite packing hand-hole, bolt (6) is set on hand-hole at the stuffing box packing cavity outer wall.
The pressure duct expansion bend that the utility model provides, the rapid pipe joint through the outer end is connected with pipeline, and is quick and easy for installation, Expanded graphite stuffing box packing good seal performance, long service life.
Four, description of drawings:
Fig. 1: a kind of structural representation of the utility model.
Five, embodiment:
Combine embodiment with reference to accompanying drawing, the utility model is further specified.
Embodiment 1, accompanying drawing have provided a kind of concrete structure of the utility model, consult Fig. 1; A kind of pressure duct expansion bend, it comprises interpolation pipe (1) and outer sleeve (2), has the connecting rod (3) of connection interpolation pipe (1) and outer sleeve (2); Rapid pipe joint (4) is set in the outer end of interpolation pipe and outer sleeve, the stuffing box packing chamber is set, have the Expanded graphite stuffing box packing (5) of injection in the stuffing box packing chamber at interpolation pipe and outer sleeve jointing place; Have the graphite packing hand-hole at the stuffing box packing cavity outer wall, bolt (6) is set on hand-hole.The pressure duct expansion bend that the utility model provides, the rapid pipe joint through the outer end is connected with pipeline, and is quick and easy for installation, Expanded graphite stuffing box packing good seal performance, long service life.
