Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a three-piece sanitary-grade fully-wrapped ball valve comprises a valve sleeve 1, a valve cover 3 and a knob 5, wherein a three-way ball 2 is rotatably connected inside the valve sleeve 1, the valve cover 3 is installed at the upper part of the valve sleeve 1, a valve rod 4 is slidably connected inside the valve cover 3, the knob 5 is installed at the upper end of the valve rod 4, a cavity 6 is arranged inside the valve cover 3, a baffle 8 is installed at the outer end of the valve rod 4 and positioned inside the cavity 6, a disc spring 7 is sleeved between the baffle 8 and the cavity 6 at the outer side of the valve rod 4, a limiting block 10 is installed at the outer end of the valve rod 4, a limiting groove 9 matched with the limiting block 10 is arranged inside the cavity 6, a control block 13 is installed at the lower end of the valve rod 4, a controlled groove 14 matched with the control block 13 is formed inside the three-way ball 2, the disc spring 7 and the baffle 8 are arranged to, thereby restricting the rotation of the three-way ball 2.

Specifically, as shown in fig. 1 to 3, the horizontal cross sections of the limiting block 10 and the control block 13 are both square structures with the same size.

Specifically, as shown in fig. 1 and 3, the inside of valve rod 4 is located the below of stopper 10 and has a recess, and the inside cover that the outside of valve rod 4 is located the recess is equipped with packing ring 11, and cushion 12 is installed in the outside of control block 13, and cushion 12 is the loop configuration, and laminates with the inner wall of valve gap 3, and the setting of recess is convenient for the installation to packing ring 11.
