Abstract
The utility model provides a corrosion-resistant ball valve structure which comprises a left valve body, a right valve body, a ceramic ball body, a valve rod, a valve rod, a filler press plate, a limit plate, a wrench and the like. The corrosion-resistant ball valve structure is characterized in that the wrench is arranged at the upper end of the valve rod, the wrench is fixedly connected with the upper end of the valve rod, the limit plate is positioned at the lower end of the wrench, the filler press plate is positioned at the lower end of the limit plate, a filler press sleeve is arranged at the lower end of the filler press plate, the filler press plate can press fillers at the lower end, a filler gasket is arranged at the bottom of the fillers, a left valve body is positioned on the outer side of the left valve body, the right valve body is arranged on the right side of the left valve body, a gasket is additionally positioned between the left valve body and the right valve body and is fixedly connected with a nut through a double-head bolt, the ceramic valve seat is positioned in the valve body, a sealing ring is arranged between the ceramic valve seat and the valve body, the ceramic ball body is arranged in the ceramic valve seat, the ceramic ball body is fixedly connected with the lower end of the valve rod, and a conical ceramic lining is fixedly embedded on the surface of overflowing medium in the valve body. The corrosion-resistant ball valve structure has the advantages of being especially suitable for strong corrosive fields, small in switch torsion, reliable in sealing, long in service life and the like.
Description
Technical field
The utility model belongs to valve and makes the field, especially relates to a kind of corrosion resistant ball valve structure.
Background technique
At present, the valve that generally uses receives the restriction of material, structure, can not adapt to the demand of bad working environments such as increasingly high wearing and tearing, deep-etching, is mainly reflected in the weak point in working life, reveals the stability that has seriously influenced system's operation greatly.Traditional valve is badly in need of reforming completely from aspects such as material, structure and manufacturing process.
The model utility content
The purpose of the utility model provides a kind of deep-etching occasion that is specially adapted to, and it is little to have a switching torque, and sealing is reliable, the corrosion resistant ball valve structure of long service life.
The technological scheme of the utility model is: a kind of corrosion resistant ball valve structure, comprise left valve barrel, right valve barrel, spheres of ceramic, valve rod, hold-down grid, limiting board, spanner etc., and it is characterized in that: the valve rod upper end is provided with spanner; Spanner is fixedly connected with the valve rod upper end, and the spanner lower end is provided with limiting board, and the limiting board lower end is provided with hold-down grid; The hold-down grid lower end is provided with the filler gland, and the filler gland is pushed down the filler of lower end, and the filler bottom is provided with the filler packing ring; The filler outside is provided with left valve barrel, and the left valve barrel right side is provided with right valve barrel, shimming between left valve barrel and the right valve barrel; Be fixedly connected with nut through stud bolt, be provided with ceramic valve seat in the valve body, be provided with seal ring between ceramic valve seat and the valve body; Be provided with spheres of ceramic in the ceramic valve seat; Spheres of ceramic is fixedly connected with the valve rod lower end, and in valve body, the overcurrent dielectric surface fixedly is installed with the ceramic chamber lining of taper.
Advantage and the good effect that the utlity model has are: be specially adapted to the deep-etching occasion, it is little to have a switching torque, and sealing is reliable, advantages such as long service life.
