Abstract
The invention relates to the technical field of auxiliary facilities of heat exchangers, and discloses a sleeve pipe structure for connecting a corrugated pipe and a baffle plate of the heat exchanger. The sleeve pipe structure is composed of a fixing clamping sleeve 1, the corrugated pipe 2 and the baffle plate 3. An outer protrusion portion of the corrugated pipe 2 is fixedly connected with the fixing clamping sleeve 1, and the baffle plate 3 which corresponds to the outer protrusion portion of the corrugated pipe 2 is fixedly connected in a clamping groove outside the fixing clamping sleeve 1. According to the structure, a common metal structure can be replaced with non-metal materials, the tight and reliable connection of the sleeve pipe for connecting the corrugated pipe and the baffle plate can be ensured, relative vibration and friction can be reduced to the greatest extent, and the structure has the advantages of being convenient to assemble and the like.
Description
Technical field
The present invention relates to heat exchanger technical field of auxiliary facilities, relate in particular to sleeve structure and method that a kind of heat-exchanger ripple pipe is connected with deflection plate.
Background technology
At present, the heat-exchanger ripple pipe of existing conventional structure and the sleeve structure that deflection plate connects and composes, by forming with the seamless pipe outer wall welding that is built-in with bellows, exist bellows and deflection plate joint sleeve gap too large by deflection plate, and its shortcoming is as follows:
(1) bellows and deflection plate joint sleeve gap are too large, constructional difficulties, and pipe impacts easy generation strenuous vibration at work, has greatly shortened the service life of bellows.
(2) bellows duration of work, frequently rubs with joint sleeve because expanding with heat and contract with cold, extruding etc., and tube surface is local easily damaged, has the unsafe factors such as medium leakage.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the sleeve structure that a kind of heat-exchanger ripple pipe is connected with deflection plate.
In order to realize foregoing invention object, the present invention adopts technical scheme as follows:
The sleeve structure that a kind of heat-exchanger ripple pipe is connected with deflection plate, formed by fixing cutting ferrule 1, bellows 2, deflection plate 3, described bellows 2 outer lug portions are fixedly connected with fixing cutting ferrule 1, and the deflection plate 3 arranging with bellows 2 outer lug portion corresponding positions is fixedly connected in the draw-in groove outside fixing cutting ferrule 1.
The sleeve structure that heat-exchanger ripple pipe is connected with deflection plate, described fixing cutting ferrule 1 is nonmetal elastic annular structure, is evenly equipped with the some cutting ferrules with deflection plate 3 combinations in nonmetal elastic annular structure.
Owing to adopting technical scheme as above, the present invention has following superiority:
The sleeve structure that heat-exchanger ripple pipe is connected with deflection plate, can improve the shortcoming that conventional structure exists, and can guarantee that bellows is connected with deflection plate joint sleeve closely reliable, reduces relative vibration and friction as far as possible.
The present invention can replace conventional metal structure by nonmetallic materials, nonmetallic materials play buffering, damping, reduce friction relatively, impact, be convenient to the advantages such as assembling, can meet any bellows of GB151-1999 condition by suitable parameters is connected with deflection plate, serviceability temperature scope allows serviceability temperature to determine according to nonmetallic materials, has general generalization.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of existing conventional heat-exchanger ripple pipe and deflection plate joint sleeve structure;
Fig. 2 is the schematic diagram of heat-exchanger ripple pipe of the present invention and deflection plate joint sleeve structure;
In figure: 1, fixing cutting ferrule; 2, bellows; 3 deflection plates.
[specific embodiment]
As shown in Figure 2, the sleeve structure that a kind of heat-exchanger ripple pipe is connected with deflection plate, formed by fixing cutting ferrule 1, bellows 2, deflection plate 3, described bellows 2 outer lug portions are fixedly connected with fixing cutting ferrule 1, and the deflection plate 3 arranging with bellows 2 outer lug portion corresponding positions is fixedly connected in the draw-in groove outside fixing cutting ferrule 1.
Described fixing cutting ferrule 1 is nonmetal elastic annular structure, is evenly equipped with the some cutting ferrules with deflection plate 3 combinations in nonmetal elastic annular structure.
This sleeve structure replaces conventional metal structure by nonmetallic materials, nonmetallic materials play buffering, damping, reduce and relatively rub, impact, and are convenient to the advantages such as assembling, can guarantee that bellows is connected with deflection plate joint sleeve closely reliable, reduce relative vibration and friction as far as possible.
