Abstract
The utility model provides a ball valve structure, which comprises a valve body, a ceramic ball body, a valve rod, a packing cover, a wrench, a ceramic body sleeve, a ceramic end body sleeve, a ceramic valve seat, an end flange and the like. The ball valve structure is characterized in that the wrench is arranged at the upper end of the valve rod, and is fixedly connected with the upper end of the valve rod; a positioning block is arranged at the lower end of the wrench; the wrench is fixed on the positioning block through a positioning pin; the packing cover is arranged at the lower end of the positioning block, and presses a packing at the lower end of the packing cover; a valve cap is arranged outside the packing at the lower end of the packing cover; the end flange is arranged outside the valve cap; an O-shaped sealing ring (A) is additionally arranged between the end flange and the valve cap, and the end flange is fixedly connected with the valve cap through bolts and a nut; the ceramic body sleeve is arranged in the lower end of the valve cap; the ceramic end body sleeve is arranged at the lower end of the ceramic body sleeve; the ceramic valve seat is arranged on the inner side of the ceramic end body sleeve; and the ceramic ball body is arranged in the ceramic valve seat, and is fixedly connected with the lower end of the valve rod. The ball valve structure has high abrasion resistance, high corrosion resistance, high washing resistance, high heat insulation performance, low switching torque and long service life.
Description
Technical field
The utility model belongs to valve and makes the field, especially relates to a kind of 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 provide a kind of have high wear-resistant, corrosion-resistant, abrasion resistance can, and heat-shielding performance is good, switching torque is little, long service life, the ball-valve structure of good airproof performance.
The technological scheme of the utility model is: a kind of ball-valve structure comprises valve body, spheres of ceramic, valve rod, Gland, positioning block, spanner, ceramic body cover, ceramic end body cover, ceramic valve seat, end flange etc.; It is characterized in that: the valve rod upper end is provided with spanner, and spanner is fixedly connected with the valve rod upper end, and the spanner lower end is provided with positioning block; Spanner is fixed on the positioning block through locating stud, and the positioning block lower end is provided with Gland, and Gland is pushed down the filler of lower end; Filler outside, Gland lower end is provided with valve gap, adds the back seal pad between valve gap and the valve rod, and the valve gap outside is provided with end flange; Add O RunddichtringO (A) between end flange and the valve gap, be fixedly connected through bolts and nuts, inside, valve gap lower end is provided with the ceramic body cover; Ceramic body cover lower end is provided with ceramic end body cover, and ceramic end body cover inboard is a ceramic valve seat, is provided with O RunddichtringO (B) and dish spring between ceramic valve seat and the ceramic end body cover; Ceramic valve seat inside is equipped with spheres of ceramic, and spheres of ceramic is fixedly connected with the valve rod lower end.
Advantage and the good effect that the utlity model has are: have high wear-resistant, corrosion-resistant, abrasion resistance ability; And heat-shielding performance is good, and switching torque is little, long service life; Because the spheres of ceramic surface finishment of the utility model is high; With ceramic valve seat to after grinding, utilize the self lubricity of pottery, can obtain good sealing effect.
