NOVELTY - An externally threaded valve tungsten manganese alloy spring island sea wind power system comprises working platforms (10) fixed and installed on electromechanical conversion unit (41) connected to storage cabinet (48), hinge (44) connected to two-way shock absorber spring screw (45), fixed leg (46), cooling pipe (47), wind wheel shaft (42) fixedly supported by wind vane wheel (43), and cooling water pump (38) connected in series to pump suction pipe (94), filter section (52) and threaded check valve (90).    USE - Externally threaded valve tungsten manganese alloy spring island sea wind power system.    DETAILED DESCRIPTION - An externally threaded valve tungsten manganese alloy spring island sea wind power system comprises working platforms (10) fixed and installed on electromechanical conversion unit (41) connected to storage cabinet (48), hinge (44) connected to two-way shock absorber spring screw (45), fixed leg (46), cooling pipe (47), wind wheel shaft (42) fixedly supported by wind vane wheel (43), and cooling water pump (38) connected in series to pump suction pipe (94), filter section (52) and threaded check valve (90). The two-way shock absorber spring screw comprises threaded rod spring, threaded spring inner cylinder, threaded guide outer cylinder, threaded first spring seat, first two-way spring and second two-way spring. The one end of threaded rod spring is fixed at double spring seat. The double spring seat and threaded spring inner cylinder is provided with axial sliding fit. The threaded rod spring other end is provided with external thread. The one end of threaded spring inner cylinder is fixed at second spring seat. The other end of threaded inner cylindrical spring is provided with an inner tube outer screw. The threaded first spring seat outer end is provided with lower end of shock absorber connected to fixed leg. The threaded guide outer cylinder is provided with cylinder screw and shock absorber head connected to hinge. The threaded check valve comprises external screw connection valve, upper conducting fluid having three positioning rib plate cylindrical surface, half-open tube, movable valve core, lower conducting fluid having lower guide hole, assembly gap and positioning three ribs on outer circular surface, taper hole, round holes, upper stepped hole, lower stepped hole, and fastening screw hole. The upper conducting fluid plane end is fixedly connected with upper cylinder and flow channel round bar connected to cylindrical valve stem. The movable valve core comprises upper tapered cylinder, upper cone cylinder, upper three connecting ribs, lower tapered cylinder, lower cone and lower three connecting ribs. The upper tapered cylinder comprises upper chamber cover. The lower tapered cylinder comprises lower chamber cover. The first two-way spring and second two-way spring is made of high strength and corrosion-resistant tungsten manganese alloy steel. The threaded spring inner cylinder, threaded guide outer cylinder and threaded rod spring is made of zirconia ceramic. The upper conducting fluid and lower conducting fluid bodies are made of zirconia ceramic. The movable valve core is made of high-strength composite nylon 6 material. The external screw connection valve is made of composite fiberglass.
