Abstract
The utility model provides a reinforced structure of a bellows coupling end, belonging to the technical field of machinery. The reinforced structure solves the problems of weak intensity, short service life and easy deformation and more complex structure and the like existing in the reinforced structure of the existing bellows coupling end. In the reinforced structure of the bellows coupling end, the coupling end at the end part of the bellows is cylindrical, the outer side of the coupling end is sheathed with a connecting sleeve and the inner side of the coupling end is fixedly connected with a cylindrical reinforced pipe. The reinforced structure of the bellows coupling end is not easily deformed or damaged, has higher stability and practical value and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bellows, particularly the ruggedized construction of bellows connecting end.
Background technique
Bellows is mainly used in effects such as compensation pipes thermal distortion, damping, absorption pipeline sedimentation and deformation, is widely used in industries such as petrochemical industry, instrument, space flight, chemical industry, electric power, cement, metallurgy.
The bellows kind: bellows mainly is divided into metal (stainless steel, carbon steel) bellows, plastic film capicitor.Other material bellows such as plastics has irreplaceable effect in fields such as medium transport, electric power threading, lathe, household electrical appliances.
For example, a kind of " the high-performance corrugated expansion joint " that its publication number of Chinese patent CN2844626Y provides, it comprises bellows and is arranged on the interior bellows backing layer of bellows that wherein the crest location in the bellows outside is provided with and strengthens ring.
Under the effect of ripple piping pressure, the bellows backing layer expands, and the bellows backing layer is expanded to strengthens the ring place, is subjected to piping pressure by strengthening rim bearing.Owing to strengthen ring for Structural Hardware, therefore, make bellows can bear bigger external force like this.
As can be seen, ripple pipelining layer is that the enhancing rim bearing is stressed in the above-mentioned patent.And the connecting end of bellows is stressed bigger in connection procedure, is easy to make the bellows connecting end to be out of shape or to damage because of stressed like this.
That is to say that its connecting end in connection procedure of the bellows in existing bellows and the above-mentioned patent is damaged easily, influences the normal use of bellows.Particularly the bellows of red copper material owing to the relation of its material, is easy to distortion or damage in connection procedure.
Summary of the invention
The purpose of this utility model is at existing in prior technology the problems referred to above, and a kind of ruggedized construction that can increase bellows intensity and bellows connecting end simple in structure is provided.
The purpose of this utility model can realize by following technical proposal: a kind of ruggedized construction of bellows connecting end, the connecting end of corrugated tube end is cylindric, the described connecting end outside is with connecting sleeve, it is characterized in that described connecting end has fixedly connected to the inner side and has been reinforcement tube cylindraceous.
The connecting sleeve at bellows connecting end place is used for being connected with other pipe fitting or valve, and usually, it is to adopt the mode that is threaded.
The connecting end of bellows does not have crest, promptly is cylindric.Connecting end is stressed bigger in connection procedure, has increased the intensity of connecting end by the reinforcement tube that is connected in the connecting end inboard.Therefore, even connecting end is subjected to bigger external force and also can be out of shape or damages in connection procedure.
In the ruggedized construction of above-mentioned bellows connecting end, the port of described connecting end is toroidal, and the inner of above-mentioned reinforcement tube is positioned at the crest place of bellows inboard, and the outer end of reinforcement tube is mutually concordant with the bottom of toroidal.
Reinforcement tube is resisted against the crest place makes the inner of reinforcement tube obtain the location, and simultaneously, the outer end of reinforcement tube makes that with the toroidal bottom is mutually concordant the port of bellows connecting end is smooth.
In the ruggedized construction of above-mentioned bellows connecting end, described reinforcement tube is made by plastic materials.
The reinforcement tube that plastic materials is made has certain intensity, and can not cause damage to bellows when packing into reinforcement tube in the bellows connecting end.
As another scheme, in the ruggedized construction of above-mentioned bellows connecting end, described reinforcement tube is made by stainless steel material.
The bellows that this material is made has enough intensity, and in use also can not be corroded.
In the ruggedized construction of above-mentioned bellows connecting end, described reinforcement tube is bonded in the connecting end inboard by glue.
Reinforcement tube is connected in firmly the inboard of bellows connecting end by glue.
Compared with prior art, the ruggedized construction of this bellows connecting end reinforcement tube that just in bellows, is connected, it does not only influence the normal use of bellows, but also has increased the intensity of bellows connecting end.Therefore, the bellows with this ruggedized construction makes that in connection procedure connecting end is not yielding or damages.
Simultaneously, have in the bellows of this ruggedized construction reinforcement tube and fixed firmly, can not become flexible, its stability in use has the higher utility of ratio than higher.
Description of drawings
Fig. 1 is the form structure schematic representation of the ruggedized construction of this bellows connecting end.
Fig. 2 is the sectional structure schematic representation of the ruggedized construction of this bellows connecting end.
Among the figure, 1, connecting end; 2, reinforcement tube; 3, connecting sleeve.
Embodiment
As shown in Figure 1, have some crests on the bellows, the end of bellows is a connecting end 1, connecting end 1 no crest, and connecting end 1 is cylindric.Be with the connecting sleeve 3 that can link with pipe fitting or valve in connecting end 1 outside.
As depicted in figs. 1 and 2, the ruggedized construction of this bellows connecting end just is arranged at connecting end 1 place of bellows.Be provided with in the connecting end 1 and be reinforcement tube 2 cylindraceous, the inner of reinforcement tube 2 is resisted against the crest place of bellows, and the outer end of reinforcement tube 2 is concordant with the port of bellows connecting end 1.
In the present embodiment, bellows adopts the red copper material to make.
When the bellows with this structure was connected with other pipe fitting or valve, connecting sleeve 3 was connected on other pipe fitting or the valve, and makes the port of other pipe fitting or the valve connecting end that is resisted against bellows 1 tightly.Usually, in order to increase sealing, between the port of connecting end 1 and other pipe fitting or valve, be provided with seal ring.
Obviously, reinforcement tube 2 is located firmly, and can not become flexible or come off.In addition, the not yielding or damage of the connecting end 1 of bellows under the effect of reinforcement tube 2.
In addition, reinforcement tube 2 can also adopt another except above-mentioned means of fixation, and promptly reinforcement tube 2 is bonded in connecting end 1 inboard by glue.
