Abstract
The invention discloses a spacing sleeve for a stainless steel pipe fitting. The spacing sleeve is made of an elastic material; the spacing sleeve for the stainless steel pipe fitting is ring-shaped; the cross section of the spacing sleeve is L-shaped; and an inner hole of the spacing sleeve can be made into a circular hole or a waist-shaped hole. The spacing sleeve for the stainless steel pipe fitting has the advantages of strong strength, convenience for mounting, attractive appearance and obvious spacing effect.
Description
Technical field
The present invention relates to a kind of separation sleeve, particularly a kind of connection separation sleeve that is used for stainless steel pipe.
Background technique
Since GB/T/19228.1～3-2003 stainless steel card was pressed the issue of pipe fitting series standard, stainless steel pipeline obtained wide popularization and application in industries such as China's city-buildings.For the connection of diameter between the Stainless Steel Tube more than the DN100mm; Usually adopt stainless steel lathe dog to substitute traditional flange and connect, and these stainless steel lathe dog connect and usually adopt cast iron bolt, cast iron nut to tighten up, and when stainless steel lathe dog and cast iron Metal Contact; Can produce differential metals contact corrosion; Cause clip to get rusty, thereby influence clip working life, also influence is installed attractive in appearance.
Summary of the invention
The problem that the present invention will solve is the deficiency that overcomes in the background technique, provides a kind of stainless steel pipe to use separation sleeve, and this stainless steel pipe is used separation sleeve; The employing polytetrafluoroethylmaterial material is processed, and intensity is high, in the form of a ring; Its sectional shape is " L " type; Be used for isolating stainless steel lathe dog and cast iron bolt, cast iron nut, easy for installation, attractive in appearance and isolation effect is obvious.
For addressing the above problem, the present invention takes following technological scheme:
A kind of stainless steel pipe of the present invention is used separation sleeve, is processed by the elastic material polytetrafluoroethylmaterial material, and in the form of a ring, its sectional shape is " L " type.
Separation sleeve endoporus and clip bolt hole are circular port, and the external diameter of separation sleeve one end is slightly less than the internal diameter of clip bolt hole, is convenient to easily put into the clip bolt hole, and the external diameter of the other end is greater than the clip diameter of bolt hole.
Separation sleeve endoporus and clip bolt hole are waist shaped hole; The waist shape profile outer diameter of separation sleeve one end is slightly less than the profile internal diameter of clip bolt waist shaped hole; Be convenient to easily put into clip bolt waist shaped hole, the circular outer diameter of the other end is greater than the profile outer diameter of clip bolt waist shaped hole.
A kind of stainless steel pipe of the present invention is used separation sleeve, is circular, owing to adopt the elastic material polytetrafluoroethylmaterial material to process, and its sectional shape be " L " type, so has the intensity height, and is easy for installation, the tangible advantage of attractive in appearance and isolation effect.
Description of drawings
Fig. 1 is a kind of enforcement structural representation of the present invention.
Fig. 2 is the cross-sectional schematic of Fig. 1.
Fig. 3 is the another kind of structural representation of implementing of the present invention.
Fig. 4 is the cross-sectional schematic of Fig. 3.
Embodiment
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of stainless steel pipe of the present invention is used separation sleeve, is circular, and its sectional shape is " L " type, is processed by elastic material, and said elastic material is a teflon.
As a kind of embodiment, separation sleeve endoporus and clip bolt hole are circular port, and the external diameter of separation sleeve one end is slightly less than the internal diameter of clip bolt hole, is convenient to easily put into the clip bolt hole, and the external diameter of the other end is greater than the clip diameter of bolt hole.
As another kind of embodiment; Separation sleeve endoporus and clip bolt hole are waist shaped hole; The waist shape profile outer diameter of separation sleeve one end is slightly less than the profile internal diameter of clip bolt waist shaped hole, is convenient to easily put into clip bolt waist shaped hole, and the circular outer diameter of the other end is greater than the profile outer diameter of clip bolt waist shaped hole.
This stainless steel pipe is used separation sleeve, and intensity is high, and is easy for installation, and is attractive in appearance and isolation effect is obvious.
