Abstract
The utility model discloses a nonmetal expansion joint, including the nonmetal inflation body that is the tube -shape, be located the installation pipe that is the tube -shape at nonmetal inflation body both ends, installation outside of tubes end is equipped with mounting flange, the external still parcel of nonmetal inflation has the covering, still be equipped with the collar that is used for connecting the covering on the installation pipe, still be equipped with the fixed establishment who is used for advancing the rampart card of covering and collar on the collar. The utility model has the advantages of it is following and effect: through the fixed loop joint for the covering is more convenient with the collar installation, has not only reduced the running cost, has also reduced the manufacturing cost of collar with the covering simultaneously.
Description
Technical field
This utility model relates to industry expansion joint field, is specifically related to a kind of non-metal expansion joint。
Background technology
Development along with science and technology, at all kinds of CFBBs, in the industries such as combustion engine waste heat boiler and chemical industry, cement, papermaking, skyscraper, it is deformed owing to expanding with heat and contract with cold between equipment and equipment, equipment and pipeline, pipeline and pipeline, generally adopting non-metal compensator, namely non-metal expansion joint compensates displacement, and absorbs vibration, reduce noise, its be mainly fabric, rubber, etc. exotic material in case can air blower of compensating, airduct run vibrations and pipe deforming。
Application number is the Chinese patent " a kind of nonmetal textile compensator " of 201010213520.2, disclose a kind of nonmetal textile compensator, it is characterised in that it comprises baffle plate (1), nonmetal astragal (2), thermal insulating filling layer (3), stainless steel silk stratum reticulare (4), heat-preservation cotton layer (5) and frame (6)；Baffle plate (1) be provided above organic frame (6), frame (6) is internal is provided with heat-preservation cotton layer (5), the upper end of heat-preservation cotton layer (5) is provided with stainless steel silk stratum reticulare (4), stainless steel silk stratum reticulare (4) upper strata is provided with thermal insulating filling layer (3), and thermal insulating filling layer (3) outer wall is provided with nonmetal astragal (2)。This patent good sealing effect, but thermal insulating filling layer and frame to be bolted when mounted, offer for bolt aperture so that first obtain when mounted in chassis wall, also must offer through hole at thermal insulating filling layer to realize installing simultaneously, comparatively bother so that make, simultaneously install time also one by one bolt installation, set-up time is relatively complicated with step, simultaneously can there is loosening to a certain extent in bolt after long-term use, finally result in overall the loosening of expansion joint, be unfavorable for life-time service。
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of non-metal expansion joint easy for installation。
For achieving the above object, this utility model provides following technical scheme: a kind of non-metal expansion joint, including tubular nonmetal expander, it is positioned at the tubular of nonmetal expander two ends and pipe is installed, described installation pipe outer end is provided with mounting flange, also it is enclosed with eyelid covering outside described nonmetal expander, described installation pipe is additionally provided with the installation ring for connecting eyelid covering, described installation ring is additionally provided with the fixed mechanism for eyelid covering and the ring wall installing ring being sticked into。
Of the present utility model being further arranged to: described fixed mechanism includes tubular retainer ring, described retainer ring is provided with for being set in eyelid covering and the draw-in groove installed on ring, and the inwall of described draw-in groove is provided with taper latch。
Of the present utility model it is further arranged to: the inwall of described draw-in groove is additionally provided with annular protrusion。
Of the present utility model it is further arranged to: described eyelid covering and install and be additionally provided with rubber ring pad between ring。
By adopting technique scheme, draw-in groove retainer ring with latch is bent inwards, eyelid covering and the gap installing loop contacts are directly diminished so that eyelid covering is more tight with installation loop contacts, realize installing, it is to avoid adopting bolt fasten in prior art needs more preparation and operation。
This utility model has an advantage that by retainer ring clamping so that eyelid covering is installed more convenient with installing ring, not only reduces running cost, also reduces the production cost installing ring with eyelid covering simultaneously。

In figure: 1, nonmetal expander；2, pipe is installed；3, baffle plate；4, eyelid covering；5, ring is installed；6, fixed mechanism；7, retainer ring；8, draw-in groove；9, latch；10, annular protrusion；11, rubber ring pad。
Detailed description of the invention
Referring to figs. 1 through Fig. 2, this utility model embodiment is described further。
A kind of non-metal expansion joint, including tubular nonmetal expander 1, nonmetal expander 1 includes the material such as aluminium silicate wool, varnished cloth, at the tubular installation pipe 2 being positioned at nonmetal expander 1 two ends, described installation pipe 2 outer end is provided with mounting flange, the inner is provided with baffle plate 3, is in a cylindrical shape fixing for nonmetal expander 1；Nonmetal expander 1 is outer is also enclosed with eyelid covering 4, installing, pipe 2 is additionally provided with the installation ring 5 for connecting eyelid covering 4, the fixed mechanism 6 being additionally provided with on ring 5 for eyelid covering 4 and the ring wall installing ring 5 being sticked into is installed, fixed mechanism 6 includes tubular retainer ring 7, retainer ring 7 is provided with for being set in eyelid covering 4 and the draw-in groove 8 installed on ring 5, the inwall of described draw-in groove 8 is provided with taper latch 9, when mounted, eyelid covering 4 is attached to nonmetal expander 1 periphery, the dual-side of eyelid covering 4 is fitted on the installation ring 5 at two ends simultaneously, then pass through draw-in groove 8 and retainer ring 7 is set on installation ring 5, after installation, with weights such as hammers, installation ring 5 can be positioned at 8 liang of walls of draw-in groove to bend inwards, make that ring 5 is installed to be sticked into with installation ring 5 laminating by eyelid covering 4, eyelid covering 4 is not fallen off, taper latch 9 on draw-in groove 8 inwall can be embedded into endothelium and install on ring 5 simultaneously, realize engaging, make installation more firm。
Being additionally provided with annular protrusion 10 on the inwall of draw-in groove 8, annular protrusion 10 can be provided with a plurality of, and cross section can be semicircle, and the existence of annular protrusion 10 makes retainer ring 7 expand and eyelid covering 4 and the contact area installing ring 5, and the pressure of the front end of semicircular ring is bigger。
It is additionally provided with rubber ring pad 11 between eyelid covering 4 and installation ring 5, increases the sealing of both times, retainer ring 7 offer deformation quantity when compression can be provided so that operate more convenient simultaneously。
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model。It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model。
