Abstract
The invention discloses a thin-wall stainless steel tube connecting pipe fitting which comprises a thin-wall stainless steel tube, a split sleeve chuck, a sealing ring, a nut and a joint seat, wherein the nut and the joint seat are sheathed at the external periphery of the thin-wall stainless steel tube; the split sleeve chuck is arranged in the nut; a raised annular rib is arranged on the split sleeve chuck; a raised annular lug is arranged on the external surface of the thin-wall stainless steel tube; the annular lug is matched with the annular rib; the sealing ring is sheathed on the thin-wall stainless steel tube and is arranged between the split sleeve chuck and the joint seat; and the nut is connected with the joint seat. The connecting pipe fitting has the advantages of high strength, convenience in assembling and disassembling, material saving and long service life.
Description
Technical field
The invention belongs to the pipeline connection technology field, be 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 object of the present invention is to provide high, the easy to loading and unloading thin-wall stainless steel pipe connected pipe fitting of a kind of join strength.
The technological scheme that the present invention 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, are equipped with in the nut and split cutting ferrule, and described splitting has protruding annular muscle on the cutting ferrule; Described thin-wall stainless steel tube outer surface has protruding annular lug; Annular lug and annular muscle are complementary, and 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 present invention has advantage: join strength is high, and is easy to loading and unloading, saves material, long service life, and cost is low.
Description of drawings
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention:
Fig. 1 structural representation of the present invention
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 is sleeved on thin-wall stainless steel 1 excircle with connection block 5, is equipped with in the nut 4 and splits cutting ferrule 2; Described splitting has protruding annular muscle 6 on the cutting ferrule 2, 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 protruding annular lug 7, 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.Join strength of the present invention is high, and is easy to loading and unloading, saves material, long service life.
