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 technique
Existing joint sealing adopts rubber sealing structure more, and sealing form, in moving link, does not possess anti-shake performance, and under sand and dust and megathermal climate condition, ageing of rubber and wearing and tearing are accelerated, and easily cause leakage, affect the performance of complete machine simultaneously.There is following shortcoming in existing conical surface seal simultaneously: high to requirement on machining accuracy; Require high to assembling; The conical surface easily scratches, and also easily causes leakage simultaneously; In sports equipment or machinery, to shaking sensitivity, easily leak; And there is following shortcoming in existing rubber seal: under high-temperature condition, rubber is easily aging, distortion etc.; In installation process, rubber parts is easily distortion also, causes poor sealing.
Summary of the invention
The object of the present invention is to provide a kind of Novel pure metal sealing joint structure, to solve the above problems.
The present invention is achieved through the following technical solutions:
A kind of Novel pure metal sealing joint structure, comprise joint A and joint B, be connected with sealing base cover at described joint A inwall, also comprise that tightening nut is for jointing A and joint B, on described joint A and joint B outer wall, be provided with the screw thread matching with tightening nut, be provided with and seal base and overlap corresponding sphere near sealing base cover one end at described joint B, described joint A, joint B, sealing base cover are metal and make, and the hardness of described sealing base cover is less than and seals base cover described in the hardness of joint B and adopt the softer metals such as copper, aluminium.Described sealing base cover and joint A interference fit.In using process, after joint B and tightening nut are fixed, inner side is connected with to the joint A precession set screw nut of sealing base cover, and tighten joint A and joint B, make sphere press primary seal base cover and then make to seal the base cover position that contacts with sphere a certain amount of resiliently deformable occurs, thereby make this joint sealing structure.
Further, for realizing better the present invention, be provided with the conical surface at described sealing base cover near sphere one end inwall.By the conical surface being set on the inwall of sealing base cover one end, can improve the sealability of sealing base cover, after being dismounted for multiple times or vibrations, its performance can be not influenced, meanwhile, its structure can couple together by other pipe joints, for changing pipeline diameter, directly be connected with hydraulic element, valve piece etc., easy accessibility, compact dimensions, sealability is high.
Further, for realizing better the present invention, described sealing base cover is made of copper.Because copper has good ductility, thereby quality is softer, has good decay resistance, easily processing, difficult wearing and tearing.Be made of copper sealing base cover, in the time that sealing base cover is received extrusion, resiliently deformable can occur, thereby make total sealing, the problems such as leakage can not occur.
Further, for realizing better the present invention, described joint B outer wall is step structure, and described tightening nut is inner concave shape structure, and the inner concave of described inner concave shape is connected on this step structure.By tightening nut inner concave is connected on step structure, can make tightening nut screw time, drive with the joint B of its clamping and move, thereby make the sphere on joint B be connected tightr with sealing base cover contact position, thereby be more conducive to improve the sealability of total, simultaneously, if occur screw thread on joint B occur stripped thread cause thread cannot interlock, in tightening nut situation about cannot tighten, also can make joint B and the relative sealing of sealing base cover by this clamping mechanism, prevent from revealing generation.
Further, for realizing better the present invention, described joint B is greater than its wall thickness away from sphere one end near the wall thickness of sphere one end.By being greater than its wall thickness away from sphere one end near the wall thickness of sphere one end, can realize structure stepped, that thicken gradually, can ensure like this mechanical strength, improve anti-vibration and the impact fatigue ability of structure.
Further, for realizing better the present invention, on described joint A inwall, be provided with cascade groove, described sealing base cover is connected in this groove.By stair-stepping groove is set, sealing base cover can be conveniently installed, meanwhile, also can make sealing structure performance better, meanwhile, also the standardization of convenient sealing base cover is made, thereby facilitates the batch production of this structure.
Further, for realizing better the present invention, the stepped structure of described joint A outer wall, is provided with near sealing base cover one end the screw thread matching with tightening nut at this step structure.Joint A outer wall is set to the step structure that diameter increases gradually, only at the position that is connected with tightening nut, screw thread is set, and can facilitate the processing of joint A, reduces processing intensity, and convenient installation.
Further, for realizing better the present invention, described joint A and joint B make by carbon steel.Because carbon steel hardness is larger, can directly make by means such as castings, contact and when relative screwing, can make to seal base cover resiliently deformable occurs, thereby reach good sealing effect at the sealing base cover softer with quality.
The present invention compared with prior art, the beneficial effect having is: the present invention is by adopting tightening nut to screw relative with joint B joint A, the sphere that makes to be provided with on joint B compresses the sealing base cover being arranged in joint A, by the power that axially fastens of tightening nut, make to be arranged on the extrusion sealing base cover on joint B, thereby make to seal base cover resiliently deformable occurs, overlap closely, couple together reliably by sphere and sealing base, realize sealing, its structure is not prone to wearing and tearing, aging, there will not be deformation effect sealing effect.The present invention can, on straight-through, elbow and special-shaped various terminal, have broad application prospects in mechanical industry.
