Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 3.

A novel fluid angular control sphere comprises a sphere body 1, wherein a medium channel 10 is arranged in the sphere body 1, a valve rod groove 11 is arranged at one end of the sphere body 1, an arc-shaped inner groove 12 is arranged at the other end of the sphere body 1, a ball 2 is arranged in the inner groove 12, a limiting part 3 is arranged at an opening of the inner groove 12, the limiting part 3 is arranged in a circular ring shape, the caliber of an inner ring of the limiting part 3 is smaller than the diameter of the ball 2, at least three positioning through holes 30 are arranged on the wall of the inner ring of the limiting part 3, an annular convex edge 31 is arranged at the end part of the limiting part 3, clamping grooves 13 with the number equal to that of the positioning through holes 30 are arranged on the inner wall of the inner groove 12 close to the opening, clamping pieces 4 are arranged in the clamping grooves 13, a spring 40 is arranged between the clamping pieces 4 and the bottom wall of the clamping grooves 13, part, the positioning through hole 30 corresponds to the clamping piece 4, the clamping piece 4 is inserted into the positioning through hole 30, and the annular convex edge 31 is positioned outside the inner groove 12 and is attached to the outer surface of the ball body 1. A pressure spring 20 is arranged between the ball 2 and the bottom wall of the inner groove 12.

When the sphere body 1 rotates, the ball 2 can replace the friction between the sphere body and the valve seat, the rolling friction stress of the ball 2 is smaller, the received friction force can be reduced, and the service life is prolonged. When the ball 2 is installed, the limiting piece 3 is clamped in the inner concave eraser, and the part of the ball 2 extends out of the inner groove 12 from the inner ring of the inner groove 12, so that the ball can roll conveniently.
