Beschreibung
Zusammenfassung:	The utility model belongs to the petroleum engineering field specifically, relates to a novel solid fixed valve of redundant formula oil -well pump. A novel solid fixed valve of redundant formula oil -well pump includes: top connection, valve bonnet assembly (valve bonnet, spring, fixture block, fixture block pin, baffle, baffle pin, disk seat, pressure cap, fixture block screw and baffle screw), valve ball, outer O type circle, interior O type circle, supporting spring, lower clutch. A novel solid fixed valve of redundant formula oil -well pump is located between cylinder of oil -well pump and the solid fixed valve of oil -well pump, the in -process at oil extraction has been realized, when the solid fixed valve of former oil -well pump became invalid, unnecessary goes out the interior tubular column of well, only transfer the operation through ground oil pumping polished rod, under sucker rod and oil pump plunger action of gravity, start the device, make it convert operating condition into by redundant stat
