Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a cross-sectional view of an embodiment of the present invention;
the device comprises a spherical surface 1, a flow channel 2, an annular sealing layer 3, an opening group 31, a closing group 32, a rib net 4, ribs 41, a fillet transition 21 and a chamfer 22.
Detailed Description
As shown in fig. 1 and 2, the ball valve ball body with small torque and long service life has a spherical surface 1 on the outer surface thereof, a flow passage 2 is arranged in the middle of the spherical surface 1, an annular sealing layer 3 protruding outwards is arranged on the spherical surface 1, the annular sealing layer 3 has two groups, namely an opening group 31 and a closing group 32, and each group has two annular sealing layers 3 in order to fit the actual situation. The opening group 31 is annularly arranged on the spherical surface 1 at the inlet and outlet ends of the flow channel 2 and forms sealing fit with the valve seat when the valve is opened, the closing group 32 is positioned on the spherical surface 1 and forms sealing fit with the valve seat when the valve is closed, and the opening and closing processes of the valve are the sealing back and forth switching between the valve seat and the opening group 31 and the closing group 32. In order to make the relative displacement between the annular sealing layer 3 and the valve seat more smooth and stable, the outer surface of the annular sealing layer 3 is in the shape of an arc curved surface, so that the pause and the pause of the opening and closing process of the valve are reduced.
The rib net 4 is fixedly arranged on the spherical surface 1, and the rib net 4 is integrally connected with the spherical surface 1 of the sphere, so that the structural strength of the sphere is enhanced, and the service life is prolonged. The rib net 4 comprises criss-cross ribs 41, wherein the ribs 41 in one arrangement direction are matched with the direction of the flow channel 2, so that the influence on the medium flow is reduced. The outer surface of the rib 41 is in a circular arc curved surface shape, and the medium flows more stably.
The protruding height of rib 41 is less than the protruding height of annular sealing layer 3 to the valve seat is opening and close the in-process, can not contact with rib 41, reduces wearing and tearing.
A fillet transition 21 is formed between the inlet and the outlet of the flow channel 2 and the spherical surface 1, and a chamfer 22 is further arranged between the fillet transition 21 and the inner wall of the flow channel 2, so that the inlet and the outlet of the flow channel 2 are prevented from being broken.
