The utility model discloses an interior cutting edge of the existing technique of cancellation to setting up the outer wall of cutting ferrule into the arc inclined plane, promoting down in gland nut's axial, the arc inclined plane is under the effect of the power with the oblique cutting part, and its opposite acting force makes in the power of cutting ferrule front end blocks the outer wall of taking over downwards, has improved group power of dialling when taking off of taking off of taking over.
Description
Technical field
The utility model belongs to line seal interconnection technique field, specifically refers to a kind of ferrule sealing structure.
Background technique
Pipe joint is a kind of static seal, is generally used for pressure≤40MPa, the working environment below temperature≤650 DEG C.Because its connection is tight, safe and reliable, convenient and practical, be widely used in the hydraulic pressure of pipe with small pipe diameter in the industry such as petrochemical industry, metallurgy, boats and ships, automobile and air pressure transmission.
The sealing principle of single deck tape-recorder sleeve joint is linear sealing, as depicted in figs. 1 and 2.Under assembling condition, cutting ferrule 2 is pushed in the conical surface of fittings body 1 under the axis of gland nut 3 promotes, the cutting ferrule front end cylindrical that wall thickness is thinner is deformed into sphere thereupon, line contact sealing is formed with fittings body internal conical surface, during cutting ferrule distortion simultaneously, in its front end, blade 5 embeds the outer wall of adapter, and a uniform annular seal grooves is extruded on the outer wall of adapter 4, outer hoop and two linear sealings of interior hoop are formed like this in the front end of cutting ferrule, thus material with pressure is sealed in fittings body and adapter, play seal action.
The interior blade processing difficulties of existing technology cutting ferrule, after interior blade sealing adapter outer wall, the de-power of dialling of adapter is generally less than 1000N, and not easily meet the demands, cause in using process, adapter comes off, the safety of serious threat vehicle.
Model utility content
The purpose of this utility model proposes improvement opportunity scheme to the cutting ferrule of existing technology, and by the technical program, while in cancelling, blade reduces difficulty of processing, that improves adapter dials de-power.
The utility model is achieved through the following technical solutions:
A kind of ferrule sealing structure, includes fittings body, cutting ferrule and adapter; Described fittings body is provided with oblique cutting part with the inner tubal wall of one end that described cutting ferrule is connected; Described cutting ferrule penetrates the tip side of described adapter; The tip side of described cutting ferrule and described adapter inserts described fittings body jointly;
Described cutting ferrule is tubular-shaped structures; The internal diameter of described cutting ferrule matches with the external diameter of described adapter; The outer wall that described cutting ferrule inserts one end of described oblique cutting part is provided with a circle inclined-plane; Described inclined-plane is arc.
The axial width on described inclined-plane is 2-3.5mm.
One end that described cutting ferrule inserts described oblique cutting part is provided with rounded corners.
In the axial cross section on described inclined-plane, the section line at place, described inclined-plane is camber line.
The inwall of the other end that described cutting ferrule is relative with the one end of inserting described oblique cutting part is provided with right angle chamfering.
The beneficial effects of the utility model are:
The utility model is by cancelling the interior blade of existing technology, and the outer wall of cutting ferrule is set to curve slope, under the axis of gland nut promotes, curve slope is under the effect of the power with oblique cutting part, its opposition makes the power of cutting ferrule front end snap onto in the outer wall of adapter downwards, improve group de-power when adapter is dialled de-, and cutting ferrule processing is simple.

Description of reference numerals
1 fittings body, 2 cutting ferrules, 3 gland nuts, 4 adapters, blade in 5,11 cutting ferrules, 12 inclined-planes, 13 rounded corners, 14 right angle chamferings, 15 fittings bodies, 16 adapters, 17 oblique cutting parts.
Embodiment
Describe the technical solution of the utility model in detail by the following examples, following embodiment is only exemplary, only can be used for explaining and the technical solution of the utility model being described, and can not be interpreted as being the restriction to technical solutions of the utility model.
The utility model provides a kind of ferrule sealing structure, as shown in Figure 3 and Figure 4, includes fittings body 15, cutting ferrule 11 and adapter 16; In each embodiment of the application, fittings body, cutting ferrule and adapter are high molecule plastic material, and the material of fittings body, cutting ferrule and adapter can identical also can not be identical, in the present embodiment, fittings body, cutting ferrule and adapter are nylon tube, and pass through injection molding.
In the following embodiment of the application, axially refer to fittings body, cutting ferrule and adapter center line direction for axially.
Described fittings body 15 is provided with oblique cutting part 17 with the inner tubal wall of one end that described cutting ferrule 11 is connected; The minimum diameter of this oblique cutting part 17 is less than the external diameter of adapter, can realize effective sealing like this; If the minimum diameter of oblique cutting part is not less than the external diameter of adapter, in gland nut axial compression process, adapter can infinitely pull and push into fittings body, cannot realize effective sealing.Described cutting ferrule 11 penetrates the tip side of described adapter 16; The tip side of described cutting ferrule and described adapter inserts the oblique cutting part of described fittings body jointly.
Described cutting ferrule 11 is tubular-shaped structures; The internal diameter of described cutting ferrule matches with the external diameter of described adapter; The outer wall that described cutting ferrule 11 inserts one end of described oblique cutting part is provided with a circle inclined-plane 12; Described inclined-plane is arc.
In the present embodiment, the axial width on described inclined-plane 12 is 2-3.5mm; In other embodiment of the application, the axial width on inclined-plane can be also other numerical value, its objective is for providing effective sealed width.
One end that described cutting ferrule inserts described oblique cutting part is provided with rounded corners 13, under being fastened in the end thrust being subject to gland nut, rounded corners part can snap in adapter outer wall under the effect to adapter direction force, and can not snap in because of former right angle side the outer wall intensity that adapter outer wall is excessive and damage is taken over.
In the axial cross section on described inclined-plane 12, the section line at place, described inclined-plane is camber line.
The inwall of the other end that described cutting ferrule 11 is relative with the one end of inserting described oblique cutting part is provided with right angle chamfering 14.
When the front end of cutting ferrule snaps in adapter outer wall, under the continuation of gland nut promotes, inclined-plane can deform, and the potted line of cutting ferrule is the tapering that the distortion of cutting ferrule front end is formed, and determines when this tapering detains distortion by cutting ferrule completely.
The above is only the description of the preferred implementation of model utility; should be understood that; due to the finiteness of literal expression; and objectively there is unlimited concrete structure; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
