Description
Technical field
The present invention relates to a kind of gasket seal, especially a kind of deep-sea Sealing.
Background technique
General Sealing cannot be adapted to the high pressure at deep-sea, high corrosive environment, often several years even some months will be out of shape loss of seal ability under the corrosion of seawater and high pressure.For the machine in abyssal environment work; the most difficult to count parts damages after change loaded down with trivial details; more especially play seal washer or the diaphragm seal of seal action, because once these hermetic devices lose sealing, likely cause whole machine scrapping under abyssal environment.For this reason, the Sealing used in this kind of machine must have longer service time, generally speaking at least takes and normally can work 10 to 20 years under abyssal environment.
Summary of the invention
The present invention is directed to deficiency of the prior art; provide a kind of deep-sea gasket seal; can under the environment of Deep-sea high voltage height corrosion normal seal operation at least 5 years, solve and to be easily corroded when Sealing uses under abyssal environment in the past thus the problem of leakage occurs.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of deep-sea gasket seal, comprise copper base skeleton, described copper base skeleton is ring, described copper base skeleton comprises obverse and reverse, described front is disposed with several and equally spaced first circular grooves identical with the described copper base skeleton center of circle, the described back side is disposed with several and equally spaced second circular grooves identical with the described copper base skeleton center of circle, described first circular groove and described second circular groove are staggered, described copper base skeleton outer ring is wound with ring baffle, described ring baffle comprises overhead gage and lower pedal, described overhead gage is provided with standing groove, described lower pedal is provided with lower standing groove, described first circular groove is provided with first compounded rubber circle, described second circular groove is provided with second compounded rubber circle, described upper standing groove and described lower standing groove are provided with the third compounded rubber circle, all described first compounded rubber circles are contour and leave space between adjacent described first compounded rubber circle, all described second compounded rubber circles are contour and leave space between adjacent described second compounded rubber circle.
In technique scheme, preferably, first annular copper silk screen is provided with between adjacent described first compounded rubber circle, described first annular copper silk screen to be fixed on described copper base skeleton and first compounded rubber circle described in sidewall contact, be provided with second annular copper silk screen between adjacent described second compounded rubber circle, described second annular copper silk screen to be fixed on described copper base skeleton and second compounded rubber circle described in sidewall contact.
In technique scheme, preferably, by weight percentage, described first compounded rubber circle and described second compounded rubber circle comprise 30% ~ 45% nitrile rubber, 25% ~ 40% silicone rubber, 5% ~ 15% acrylate rubber, 10% ~ 15% fluorine rubber, 10% ~ 25% fluorosioloxane rubber.
In technique scheme, preferably, by weight percentage, described first compounded rubber circle and described second compounded rubber circle comprise 37.5% nitrile rubber, 30% silicone rubber, 10% acrylate rubber, 10% fluorine rubber, 12.5% fluorosioloxane rubber.
In technique scheme, preferably, by weight percentage, the third described compounded rubber circle comprises 20% ~ 30% nitrile rubber, 15% ~ 35% silicone rubber, 15% ~ 25% acrylate rubber, 15% ~ 20% fluorine rubber, 20% ~ 30% fluorosioloxane rubber.
In technique scheme, preferably, by weight percentage, the third described compounded rubber circle comprises 25% nitrile rubber, 20% silicone rubber, 20% acrylate rubber, 15% fluorine rubber, 20% fluorosioloxane rubber.
Such setting, in order to the sealed environment that seal ring can be allowed to be more suitable for deep-sea, the rigidity that this gasket seal combines with compounded rubber with copper base skeleton and compression resilience to zoarium to realize sealing mechanism.Copper base skeleton can strengthen the anti-pressure ability of gasket seal, and protection rubber is not subject to the destruction of face pressure and interior external pressure, to play better seal action.On contact end face, the tooth-shape structure of copper base skeleton improves the protective ability of composite rubber material and the elastic deformability of pad.And change linear sealing into from face sealing in the past, linear sealing can reduce surface of contact, makes the interface pressure of copper base skeleton higher, and face pressure is more even.The every one side of copper base skeleton has several first compounded rubber circles and second compounded rubber circle, and the first compounded rubber circle in every face and second compounded rubber circle can touch sealing workpiece.Simultaneously arrange ring baffle at copper base skeleton outward edge, the Main Function of ring baffle is the leakage preventing from copper base skeleton in abyssal environment to be subject to collision deformation causing.On ring baffle, arrange standing groove and lower standing groove, upper standing groove and lower standing groove are provided with the third compounded rubber circle, and the third compounded rubber circle can prop up the edge of workpiece simultaneously, forms first sealing protection circle.In order to prevent the distortion of first compounded rubber circle and second compounded rubber circle, at adjacent first compounded rubber circle and adjacent second compounded rubber circle, first annular copper silk screen and second annular copper silk screen are set, first annular copper silk screen and second annular copper silk screen have certain deformation-recovery degree, all the time adjacent first compounded rubber circle or adjacent second compounded rubber circle can be propped up, when being subjected to greater impact power, first annular copper silk screen and second annular copper silk screen can provide elasticity holding power for first compounded rubber circle and second compounded rubber circle, prevent first compounded rubber circle and the distortion of second compounded rubber circle.By weight percentage, first compounded rubber circle and second compounded rubber circle comprise 37.5% nitrile rubber, 30% silicone rubber, 10% acrylate rubber, 10% fluorine rubber, 12.5% fluorosioloxane rubber.Third compounded rubber circle comprises 25% nitrile rubber, 20% silicone rubber, 20% acrylate rubber, 15% fluorine rubber, 20% fluorosioloxane rubber.The major ingredient of this bi-material is identical, but batching percentage is inconsistent, and make the third compounded rubber circle have more corrosion resistance, first compounded rubber circle and second compounded rubber circle have more elasticity.
Compared with prior art, the invention has the beneficial effects as follows: can under the environment of Deep-sea high voltage height corrosion normal seal operation at least 10 years, solve and to be easily corroded when Sealing uses under abyssal environment in the past thus the problem of leakage occurs.
