In order to achieve the above purpose, the utility model adopts the technical scheme that: a C-shaped fluoroplastic lined regulating ball valve comprises a valve body, wherein an accommodating space is formed in the valve body, and a feeding hole and a discharging hole are formed in the valve body; the top of valve body is equipped with the valve gap, and the valve rod passes the valve gap is located in the accommodation space, still include:
the ball core is arranged at the lower end of the valve rod, and the feed port and the discharge port are communicated through the ball core; wherein, the ball core is in a C shape;
the valve seat is arranged in the valve body, one side of the ball core is in contact with the valve seat, and a material through hole is formed in the valve seat.
Furthermore, the valve body comprises a left valve body and a right valve body which are symmetrically arranged, and the bottom of the joint of the left valve body and the right valve body is tooth-shaped and sealed.
Furthermore, a packing assembly is further arranged between the bottom of the valve cover and the valve body, and the packing assembly comprises a belleville spring, a gasket and packing which are sequentially connected from top to bottom.
Further, the packing is PTFE packing.
Furthermore, an elastic sealing ring A and an elastic sealing ring B are arranged between the valve seat and the left valve body in the transverse direction and the radial direction respectively.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the utility model discloses the C type lining fluoroplastic adjusts ball valve, the ball core adopts C type hemisphere, thereby realizes different circulation ability according to calculating the hole shape of opening different shapes on the disk seat simultaneously, utilizes disc spring to fill the wearing and tearing of packing, guarantees the leakproofness, and the moment of torsion when using simultaneously keeps invariable relatively.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of portion A of FIG. 1;
