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 under the corrosion of seawater and high pressure, be out of shape loss of seal ability.For the machine in abyssal environment work; the most difficult to count change after parts damages loaded down with trivial details; more especially play seal washer or the diaphragm seal of seal action, once because these sealing components and parts have been lost sealing, likely cause whole machine scrapping under abyssal environment.For this reason, the Sealing using in this class machine must have longer service time, generally speaking at least takes and can under abyssal environment, normally work 10 to 20 years.
Summary of the invention
The present invention is directed to deficiency of the prior art; a kind of deep-sea gasket seal is provided; under the environment that can corrode at deep-sea high pressure height, normal seal operation is at least 5 years, thereby solved when Sealing is used under abyssal environment in the past, is easily corroded 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, on described overhead gage, be provided with standing groove, on described lower pedal, be provided with lower standing groove, on described first circular groove, be provided with first compounded rubber circle, on described second circular groove, be provided with second compounded rubber circle, on described upper standing groove and described lower standing groove, be provided with the third compounded rubber circle, between the contour and adjacent described first compounded rubber circle of all described first compounded rubber circles, leave space, between the contour and adjacent described second compounded rubber circle of all described second compounded rubber circles, leave space.
In technique scheme, preferably, between adjacent described first compounded rubber circle, be provided with first annular copper silk screen, described first annular copper silk screen is fixed on described copper base skeleton and the first compounded rubber circle described in sidewall contact, between adjacent described second compounded rubber circle, be provided with second annular copper silk screen, described second annular copper silk screen is fixed on described copper base skeleton and the 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, preferred, 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, preferred, 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, preferred, 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.
Arrange like this, in order to allow seal ring be more suitable for the sealed environment at deep-sea, rigidity and compression resilience that this gasket seal combines with compounded rubber with copper base skeleton are realized sealing mechanism to zoarium.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 has improved the protective ability of composite rubber material and the elastic deformability of pad.And from face sealing in the past, change linear sealing into, linear sealing can be dwindled surface of contact, makes the interface pressure of copper base skeleton higher, and face is pressed 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 of every and second compounded rubber circle can touch sealing workpiece.At copper base skeleton outward edge, ring baffle is set, the Main Function of ring baffle is to prevent that copper base skeleton is subject to the leakage that collision deformation causes in abyssal environment simultaneously.Standing groove and lower standing groove are set on ring baffle, on upper standing groove and lower standing groove, are provided with the third compounded rubber circle, 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, can prop up all the time adjacent first compounded rubber circle or adjacent second compounded rubber circle, 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.The 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 the percentage of preparing burden is inconsistent, makes the third compounded rubber circle have more corrosion resistance, and first compounded rubber circle and second compounded rubber circle have more elasticity.
Compared with prior art, the invention has the beneficial effects as follows: under the environment that can corrode at deep-sea high pressure height, normal seal operation is at least 10 years, thereby solved when Sealing is used under abyssal environment in the past, is easily corroded the problem of leakage occurs.
