The present invention is achieved in that
Offshore drilling platform preventer test unit, comprises supporting seat, female joint and plain flange, wherein: be provided with the through hole through flange diameter in plain flange, is processed with screw buckle respectively at the two ends of flange diameter through hole; The center, upper surface of plain flange is provided with blind hole and the shrinkage pool face around blind hole, and this blind hole is through with the through hole through flange diameter; The upper end of female joint is processed with screw buckle, center, bottom is provided with central blind hole and the through hole through female joint diameter, female joint lower end is fixed in the shrinkage pool face, upper surface of plain flange, and keeps the central blind hole of female joint to dock through with the upper surface blind hole of plain flange; Supporting seat is fixed on the lower surface of plain flange.
Such scheme also comprises:
Screw hole and closure gasket groove is provided with in plain flange periphery; Supporting seat, connect support post on support seat board after, is fixedly connected in the shrinkage pool face of plain flange lower surface.Bracket is provided with in the junction supporting seat board and support post.
One end of plain flange diameter through hole connects two male joint and union assembly successively, and the other end connects plug.
The two male joints be connected with plain flange edge diameter through hole, plug are tapered thread; The screw buckle of female joint upper end is inner conical screw thread.
Between preventer test unit technology of the present invention and existing Vehicle the technology of preventer test unit distinguish be plain flange thickness in be provided with through hole through flange diameter as the tube channel of test(ing) liquid, eliminate the test accessories connected beyond plain flange; Thus, simplify the annex of land test, be more applicable for installation and the usage space of platform.
Effect of the present invention:
1, this test unit mainly reserves position of sound production in place at platform preventer, and this test unit, namely as the base laying preventer, can be used as test unit again; While not increasing platform cost, add thereupon preventer test test battery platform tool, its improve and avoid change operation loaded down with trivial details, marine transportation inconvenience, platform structure strengthen, the drawbacks such as the stability loading of platform.
2, which simplify the annex of land test, be more applicable for installation and the usage space of platform,
Without the need to increasing usable floor area on platform, compact conformation is reasonable, safe and reliable, actuating convenient, it is simple, practical to implement, and can improve the service efficiency of platform, make the facility of platform more perfect, reasonable, practical.
3, implement simply.
