The utility model has the advantages of high strength connection and high sealing performance.
Description
Technical Field
The utility model belongs to the technical field of pipe fittings, and relates to a corrugated hose, in particular to a novel fuel gas stainless steel corrugated hose.
Background
The joint can be fixed at the tip of bellows in general, makes bellows and other pipe fitting pipelines meet through the joint, but the joint strength between present bellows and the joint is not high, because in some fields, the medium impact force through the bellows is high, can lead to the bellows to drop like this, separates with the joint, influences the use.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provides a novel gas stainless steel corrugated hose with high connection strength.
The aim of the utility model can be achieved by the following technical scheme: the utility model provides a novel stainless steel corrugated fuel gas hose, includes hose body and is fixed in the joint of hose body tip, its characterized in that, the joint terminal surface outwards extend and be used for compressing tightly the structure of hose body, the shaping has a plurality of intervals protruding establish and form the sealed bulge loop of sealed effect with the hose body between the inner wall of joint, sealed bulge loop longitudinal section be trapezium structure, and the interior terminal surface of this sealed bulge loop covers there is one deck sealing grease.
In the novel gas stainless steel corrugated hose, the compression structure is composed of a three-section structure, and is respectively a transition section connected with the joint, an inner pressure section extending outwards from the transition section and a tilting section extending outwards from the inner pressure end, wherein the inner pressure section is used for the hose body to pass through and is extruded with the hose body to form an inner pressure tightening effect.
In the novel gas stainless steel corrugated hose, the surface of the inner pressure section is provided with the elastic layer.
Compared with the prior art, the novel gas stainless steel corrugated hose has the advantages of high strength connection and high sealing performance.
Drawings
Fig. 1 is a structural view of the novel gas stainless steel corrugated hose.
Fig. 2 is a cross-sectional view of the novel gas stainless steel corrugated hose.
In the figure, 1, a hose body; 2. a joint; 3. sealing the convex ring; 4. a transition section; 5. an internal pressure section; 6. a tilting section; 7. and (5) compacting the structure.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
As shown in fig. 1 and 2, the novel gas stainless steel corrugated hose comprises a hose body 1 and a connector 2 fixed at the end part of the hose body 1, wherein the end surface of the connector 2 is provided with a compacting structure 7 which extends outwards and is used for compacting the hose body 1, the inner wall of the connector 2 is provided with a plurality of sealing convex rings 3 which are arranged at intervals in a protruding mode and form a sealing effect with the hose body 1, the longitudinal section of each sealing convex ring 3 is of a trapezoid structure, and the inner end surface of each sealing convex ring 3 is covered with one layer of sealing grease.
Preferably, the pressing structure 7 is composed of a three-section structure, and is respectively a transition section 4 connected with the joint 2, an inner pressure section 5 extending outwards from the transition section 4 and a tilting section 6 extending outwards from the inner pressure end, wherein the inner pressure section 5 is used for the hose body 1 to pass through and is extruded with the hose body 1 to form the tightening effect of the inner pressure.
Preferably, the inner pressure section 5 has an elastic layer on its surface.
The hose body 1 is connected into the joint 2, the hose body 1 contacts with the inner pressure section 5 and the elastic layer on the surface of the inner pressure section, so that the elastic layer deforms, and meanwhile, the inner pressure section 5 acts on the hose body 1 through the elastic layer under the material characteristic (stainless steel) of the joint 2, so that the hose body 1 is deformed to a certain degree and is supported and fixed with high strength; and then the secondary fixing and sealing effects are achieved through the sealing grease on the surfaces of the sealing convex rings 3.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
Although the terms of the hose body 1, the nipple 2, the sealing collar 3, the transition section 4, the inner pressure section 5, the raising section 6, the pressing structure 7, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
