Problems solved by technology

[0002] The globe valve is a forced sealing valve. When the existing globe valve is in use, because the globe valve is generally opened or closed by cutting up and down, it is impossible to adjust the flow rate of the globe valve. For this reason, we propose Valve stem of a flow regulating cut-off valve

Abstract

The invention discloses a valve stem of a flow regulating shut-off valve in the technical field of shut-off valves. The valve stem comprises a valve body; a fixed ball is arranged in the center of aninner cavity of the valve body; the fixed ball is a hollow sphere; the outer walls of the left and right sides of the fixed ball are provided with holes; a rotary ball is movably arranged in the innercavity of the fixed ball; the inner cavity of the rotary ball is provided with a through hole; the through hole and the holes are located in the same horizontal line; the top of the rotary ball is provided with a valve stem body; the top end of the valve stem body extends to the outer wall of the top of the valve body; the outer wall of the top of the valve body is provided with a mounting seat;the outer walls of the left and right sides of a sleeve are provided with connecting rods; and the ends, away from the sleeve, of the connecting rods are connected with positioning rods. By rotating arotary plate, the valve stem body drives the rotary ball to rotate, thus, the holes and the through hole coincide, by changing the coincidence angle of the holes and the through hole, the flow of theshut-off valve is changed, and thus the flow of the shut-off valve can be adjusted as demanded.

Description

technical field [0001] The invention relates to the technical field of stop valves, in particular to a valve stem of a flow regulating stop valve. Background technique [0002] The globe valve is a forced sealing valve. When the existing globe valve is in use, because the globe valve is generally opened or closed by cutting up and down, it is impossible to adjust the flow rate of the globe valve. For this reason, we propose A valve stem of a flow regulating cut-off valve. Contents of the invention [0003] The object of the present invention is to provide a valve stem of a flow regulating cut-off valve to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a valve stem of a flow regulating stop valve, including a valve body, a fixed ball is arranged in the center of the inner cavity of the valve, and the fixed ball is a hollow sphere, and th...
