Abstract
The utility model discloses an isolation sleeve for a stainless steel pipe fitting, which is made from elastic material. The isolation sleeve for the stainless steel pipe fitting forms an annular shape, the cross section forms an L shape, and an inner hole can be made into a circular hole or a kidney hole. The isolation sleeve for the stainless steel pipe fitting has the advantages that the strength is high; the isolation sleeve is convenient to install; the appearance is attractive; and the isolation effect is obvious.
Description
Technical field
The utility model 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 pressure pipe part series standard issue, stainless steel pipeline obtains 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 adopting stainless steel lathe dog to substitute traditional flange connects, and these stainless steel lathe dog connections 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.
The model utility content
Problem to be solved in the utility model is the deficiency that overcomes in the background technique, a kind of stainless steel pipe separation sleeve is provided, this stainless steel pipe separation sleeve, the employing polytetrafluoroethylmaterial material is made, the intensity height, 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 utility model is taked following technological scheme:
A kind of stainless steel pipe separation sleeve of the present utility model is made 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 separation sleeve of the present utility model is circular, owing to adopt the elastic material polytetrafluoroethylmaterial material to make, 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.

Fig. 1 is a kind of enforcement structural representation of the present utility model.
Fig. 2 is the cross-sectional schematic of Fig. 1.
Fig. 3 is the another kind of structural representation of implementing of the present utility model.
Fig. 4 is the cross-sectional schematic of Fig. 3.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of stainless steel pipe separation sleeve of the present utility model is circular, and its sectional shape is " L " type, is made by elastic material, and described 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 separation sleeve, the intensity height, easy for installation, attractive in appearance and isolation effect is obvious.
