Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a split nut, includes corrugated stainless steel pipe 1, interior nut 3 and outer nut 7, the cover is equipped with heat preservation 4 on corrugated

stainless steel pipe

1, 4 one side covers of heat preservation are equipped with interior nut 3, corrugated stainless steel pipe 1 one end has been beaten ripples plane 2, interior nut 3 one side is equipped with jump ring 5, jump ring 5 is located between ripples plane 2 and the interior nut 3 of beating, jump ring 5 card is located on ripples plane 2, interior nut 3 is arranged in heat preservation 4 one side with between jump ring 5, the cover is equipped with outer nut 7 on the interior nut 3, the positive thread 8 that corresponds with interior nut 3 is seted up to one end in the outer nut 7, first reverse thread 9 has been seted up to the other end in the outer nut 7.
