Abstract
The invention discloses a novel pure-metal seal joint structure which comprises a joint A and a joint B. A sealing base sleeve is connected to the inner wall of the joint A in a clamped mode. The novel pure-metal seal joint structure further comprises a fastening nut. Threads matched with the fastening nut are arranged on outer walls of the joint A and the joint B, a spherical surface corresponding to the sealing base sleeve is arranged at one end close to the sealing base sleeve, of the joint B, the joint A, all of the joint B and the sealing base sleeve are made of metal, and the hardness of the sealing base sleeve is smaller than that of the joint B. The joint A and the joint B are oppositely screwed through the fastening nut to enable the spherical surface arranged on the joint B to be pressed and arranged on the sealing base sleeve in the joint A, the spherical surface arranged on the joint B extrudes the sealing base sleeve through axial fastening force of the fastening nut, and accordingly the sealing base sleeve deforms elastically. Sealing is achieved through tight and reliable connection of the spherical surface and the sealing base sleeve, the structure is not easily abraded and does not age, and deformation influencing the sealing effect does not occur.
Description
Technical field
The present invention relates to a kind of Novel pure metal sealing joint structure.
Background technology
Existing joint sealing many employings rubber sealing structure, this seal form is in moving link, no
Possessing anti-shake performance, simultaneously under the conditions of sand and dust and megathermal climate, ageing of rubber and abrasion are accelerated,
Easily cause leakage, affect the performance of complete machine.It is right that the most existing conical surface seal has the disadvantage in that
Requirement on machining accuracy is high；Height is required to assembling；The conical surface easily scratches, and also easily causes leakage simultaneously；?
In sports equipment or machinery, to vibrations sensitivity, easily leak；And there is following lacking in existing rubber seal
Point: in the case of a high temperature, rubber is the most aging, deformation etc.；In installation process, rubber parts the most easily becomes
Shape, causes poor sealing.
Summary of the invention
It is an object of the invention to provide a kind of Novel pure metal sealing joint structure, above-mentioned to solve
Problem.
The present invention is achieved through the following technical solutions:
A kind of Novel pure metal sealing joint structure, including joint A and joint B, at described joint A inwall card
It is connected to seal base sleeve, also includes that clamp nut for jointing A and joint B, described joint A and connects
It is provided with, on head B outer wall, the screw thread matched with clamp nut, at described joint B near sealing base
Set one end is provided with the sphere corresponding with sealing base sleeve, and described joint A, joint B, sealing base sleeve are equal
Make for metal, the hardness of described sealing base sleeve less than joint B hardness described in seal base sleeve use copper,
The metal that aluminum etc. are softer；The described joint B wall thickness near sphere one end is more than it away from sphere one end
Wall thickness.Described sealing base sleeve and joint A interference fit.During use, by joint B and fastening spiral shell
After parent phase is fixing, nut is fixed in the joint A precession that inner side is connected with sealing base sleeve, and tightens joint A
With joint B, make sphere press primary seal base sleeve so that make sealing base sleeve contact with sphere position occur one
Quantitative elastic deformation, so that this junction sealing structure.
Further, for the present invention is better achieved, in described sealing base sleeve near sphere one end inwall
It is provided with the conical surface.By arranging the conical surface on the inwall of sealing base sleeve one end, it is possible to increase seal base sleeve
Sealing property, after being dismounted for multiple times or vibrations, its performance will not be impacted, and meanwhile, its structure can be with it
He couples together by pipe joint, is used for changing pipeline diameter, is directly connected to Hydraulic Elements, valve block etc.,
Easy accessibility, compact dimensions, sealing property is high.
Further, for the present invention is better achieved, described sealing base sleeve is made of copper.Owing to copper has
There is good ductility, thus quality is softer, has preferable decay resistance, is easily worked, no
Easily wear and tear.It is made of copper sealing base sleeve, when sealing base sleeve and receiving extrusion, bullet can occur
Property deformation so that total seal, the problems such as leakage will not occur.
Further, for the present invention is better achieved, described joint B outer wall is step structure, institute
Stating clamp nut is concave shaped structure, and the inner concave of described concave shaped is connected on this step structure.
By clamp nut inner concave is connected on step structure, it is possible to drive when making clamp nut screw
Move with the joint B of its clamping, so that the sphere on joint B connects with sealing base sleeve contact site
Connect more tight, thus be more beneficial for improving the sealing property of total, meanwhile, if it occur that connect
In the case of screw thread on head B occurs that stripped thread causes thread to be engaged, clamp nut cannot tighten,
It also is able to make joint B and seal base sleeve opposing seal by this clamping body, prevents from revealing generation.
Further, for the present invention is better achieved, the described joint B wall thickness near sphere one end is big
In it away from the wall thickness of sphere one end.By the wall thickness near sphere one end more than it away from sphere one end
Wall thickness, structure stepped, that gradually thicken can be realized, so ensure that mechanical strength, carry
The anti-vibration of high structure and impact fatigue ability.
Further, for the present invention is better achieved, described joint A inwall is provided with stepped
Groove, described sealing base sleeve is connected in this groove.By arranging stair-stepping groove, it is possible to convenient
Install and seal base sleeve, simultaneously, it is also possible to make sealing structure performance more preferable, meanwhile, be also convenient for sealing base
The standardization of set makes, thus facilitates the batch production of this structure.
Further, for the present invention is better achieved, described joint A and joint B is made by carbon steel.
Owing to carbon steel hardness is bigger, it is possible to directly made by means such as castings, in the sealing softer with quality
When base sleeve contacts and relatively screws, it is possible to make sealing base sleeve generation elastic deformation, thus reach good
Sealing effectiveness.
The present invention compared with prior art, has the beneficial effect that the present invention passes through to use fastening spiral shell
Mother screws relative with joint B for joint A, makes the sphere being provided with on joint B compress and is arranged on joint A
In sealing base sleeve, axially fasten power by clamp nut so that be arranged on the sphere on joint B
Crush seal base sleeve, so that sealing base sleeve generation elastic deformation, tight with sealing base sleeve by sphere,
Couple together reliably, it is achieved seal, its structure be difficult to occur abrasion, aging, do not have deformation
Affect sealing effectiveness.The present invention may be used for leading directly to, on the various terminal of elbow and abnormal shape, at machinery
Industry has broad application prospects.
