Abstract
The utility model discloses a connecting pipe fitting for a thin-wall stainless steel pipe, comprising the thin-wall stainless steel pipe, a split chuck sleeve, a sealing ring, a nut and a joint base, wherein the nut and the joint base are sheathed on the outer circumference of the thin-wall stainless steel pipe; the nut is internally provided with the split chuck sleeve; the split chuck sleeve is provided with convex ring-shaped ribs; the outer surface of the thin-wall stainless steel pipe is provided with convex ring-shaped lugs; the ring-shaped lugs are matched with the ring-shaped ribs; the sealing ring is sheathed on the thin-wall stainless steel pipe and arranged between the split chuck sleeve and the joint base; and the nut is connected with the joint base. The connecting pipe fitting is high in connecting strength and convenient for assembly, saves material and has long service life.
Description
Technical field
The utility model belongs to the pipeline connection technology field, is specifically related to a kind of thin-wall stainless steel pipe connected pipe fitting.
Background technique
There is a large amount of defectives in the normally used thin-wall stainless steel pipe connected pipe fitting of people at present: the join strength of pipe fitting and thin-wall stainless steel is low, has the external force effect to deform and to leak slightly; The extending amount of connection pipe fitting can't be reserved, and very easily is out of shape because of expanding with heat and contract with cold, thereby has shortened working life of pipeline greatly; Very inconvenience of loading and unloading of existing connection pipe fitting and maintenance careless slightlyly in the cargo handling process will damage pipeline.
Summary of the invention
The purpose of this utility model is to provide a kind of join strength height, thin-wall stainless steel pipe connected pipe fitting easy to loading and unloading.
The technological scheme that the utility model adopted is: the thin-wall stainless steel pipe connected pipe fitting, comprise thin-wall stainless steel, split cutting ferrule, seal ring, nut and connection block, described nut and connection block are sleeved on the thin-wall stainless steel excircle, be equipped with in the nut and split cutting ferrule, the described annular muscle that projection is arranged on the cutting ferrule of splitting, described thin-wall stainless steel tube outer surface has the annular lug of projection, annular lug and annular muscle are complementary, described seal ring is enclosed within on the thin-wall stainless steel and is arranged on and splits between cutting ferrule and the connection block, and described nut links to each other with connection block.
The described cutting ferrule of splitting can radially separate, and also can radially close up.
Described seal ring one end band outer cone, an end is straight cover, the end that described sealing astragal directly overlaps with split the cutting ferrule end and annular lug is complementary, described seal ring has an end of outer cone and connection block end to be complementary.
The utlity model has following advantage: the join strength height, easy to loading and unloading, save material, long service life, cost is low.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 structural representation of the present utility model
Sequence number among the figure: 1, thin-wall stainless steel, 2, split cutting ferrule, 3, seal ring, 4, nut, 5, connection block, 6, annular muscle, 7, annular lug.
Embodiment
As shown in Figure 1, a kind of thin-wall stainless steel pipe connected pipe fitting, comprise thin-wall stainless steel 1, split cutting ferrule 2, seal ring 3, nut 4 and connection block 5, described nut 4 and connection block 5 are sleeved on thin-wall stainless steel 1 excircle, are equipped with in the nut 4 and split cutting ferrule 2; The described annular muscle 6 that projection is arranged on the cutting ferrule 2 of splitting, the described cutting ferrule 2 of splitting can radially separate, and also can radially close up; Described thin-wall stainless steel 1 outer surface has the annular lug 7 of projection, and annular lug 7 is complementary with annular muscle 6; Described seal ring 3 is enclosed within on the thin-wall stainless steel 1 and is arranged on and splits between cutting ferrule 2 and the connection block 5, described seal ring 3 one end band outer cones, one end is straight cover, one end of the straight cover of described seal ring 3 bands with split cutting ferrule 2 ends and annular lug 7 is complementary, described seal ring 3 has an end of outer cone and connection block 5 ends to be complementary; Described nut 4 is threaded with connection block 5.The utility model join strength height, easy to loading and unloading, save material, long service life.
