Abstract
The utility model discloses a double C-shaped metal sealing device, which is composed of a supporting ring (4) and an obturating ring, wherein, the supporting ring (4) is arranged in the circular space of a cross joint body (5, 6) and a bushing (3); the obturating ring is arranged on the supporting ring (4). The utility model is characterized in that the obturating ring is formed by upper and lower metal obtruating rings (1, 2) cooperating with each other, and the cooperating end face of the upper and lower metal obturating rings is an inclined plane (7). The other end face of the upper and lower obturating rings (1, 2) presents a double C-shaped salient (8). The utility model is made of metal and has the advantages of corrosion resistance, ageing resistance, antiwear and long service life. The end face presents double C-shaped and salient upper and lower metal obturating rings, and the deformation is easy and the sealing effect is good.
Description
Technical field
The utility model relates to a kind of two " C " type metal sealing devices that are applicable to Sealed casing pipe in the well head.
Background technology
The sleeve pipe secondary seal that uses in the present known well head no matter be need injection moulding or exempt from injection moulding be nonmetals, nonmetals anti-aging, anti-high and low-temp, anticorrosive, aspect effect such as resistance to wear is bad, be subjected to the wearing and tearing of the acute variation of immersion, temperature of Korrosionsmedium and movement parts and lost efficacy, leakage phenomenon takes place easily, and application life is shorter.
Summary of the invention
The purpose of this utility model is: a kind of two " C " type metal sealing device is provided, solves anti-aging, anticorrosive, the problem of resistance to wearing, increase the service life, improve sealing effectiveness, be applicable to the various coarse sleeve pipes of sealing.
Technical solution of the present utility model is: the sealing device is made up of Supporting ring and sealing ring, annular space mounting support ring at four-way body and sleeve pipe, sealing ring is installed on the Supporting ring, it is characterized in that: sealing ring is cooperated by metal o-ring up and down and forms, the counterface of metal o-ring is the inclined-plane up and down, and the other end of metal o-ring is two " C " type projectioies up and down.
During installation, mounting support ring in the annular space of sleeve pipe and four-way body, Supporting ring is located on the four-way body, the cooperation of metal o-ring inclined-plane is installed on the Supporting ring up and down, two " C " type crownings of last metal o-ring are to the four-way body, and two " C " type crownings of following metal o-ring are to sleeve pipe; During use, utilize the inclined-plane of upper and lower metal o-ring to make the tighten effect lateral expansion distortion of the vertical magnitude of interference by the connecting bolt of upper and lower flange when being assembled, two " C " type projectioies of last metal o-ring produce distortion and closely bond together with the four-way body, two " C " type projectioies of following metal o-ring produce distortion and closely bond together with sleeve pipe, thereby realize the metallic seal of sleeve pipe.
The utlity model has following advantage: 1, the sealing device is made by metal, anticorrosive, anti-aging, resistance to wear, long service life; 2, the end face of upper and lower metal o-ring is two " C " type projectioies, and is yielding, good sealing effect.
