Structure of a floating-ball valve
First Claim
1. An improved structure of a floating-ball valve for industrial fluid comprising a valve seat, a valve insert, a cap, a crankshaft, a float and a floating arm, wherein a valve chamber is formed at an internal of the valve seat, the internal of the valve seat having a water inlet, the internal of the valve seat and the water inlet being pipe holes of various diameters, a lower section of the valve chamber being provided with a water outlet and an elongated slot in communication with the water outlet, a bottom of the valve seat being provided with a pair of corresponding protruded members each pivotally mounted with a rocking arm, one end of the crankshaft being connected to the floating arm, the valve insert being mounted within the valve chamber characterized in that a vertical water-blocking wall is formed in between the valve chamber and the water inlet, and the valve insert consists of a metallic valve stem and a plastic valve plug, the valve plug has a front protruded rim and a rear conical face, an external wall of the protruded rim is sealable with a wall of the water inlet to form a first water-blocking structure, and the conical face is sealable with a wall hole of the water-blocking wall to form a second water-blocking structure, the crankshaft is substantially L-shaped and pivots in between the two protruded members, a top end of the crankshaft is a rocking member being inserted into a cylindrical slot, and another other end of the crankshaft is connected to an end of the floating arm, and an opening at an end of the valve seat is provided with a plurality of external threads for mounting with a threaded cap to seal the opening, an end of the crankshaft has a pore for mounting with the floating arm, an end handle of the crankshaft has a center hole and a plurality of positioning holes arranged in a fan-like manner, and the end handle of the floating arm is provided with a front and a rear pores, one of the pores is for a center hole of the crankshaft and the other for a positioning hole of the crankshaft, the end handle of the crankshaft is provided with a geared hole for positioning of a hexagonal screw nut, the cylindrical slot is mounted at a center bottom of the valve stem, the valve plug is provided with a threaded hole which is used for mounting with a threaded bolt, and the valve plug is provided with a pore for mounting with the valve stem.
