Problems solved by technology

[0003] In use, the ball valve controls the relative size between the diversion hole on the ball and the through hole of the valve body by operating the valve stem, and then controls the flow rate of liquid or gas; but in the actual use process, when the gas or liquid flows The pressure caused by the through hole inside the sphere, the flow of liquid or gas is difficult to control, and the well-controlled flow of liquid or gas impacts the sphere to generate pressure, which makes the sphere rotate and the flow of gas or liquid becomes larger, especially in some specific In the application occasions, the gas or liquid flow controlled by the existing ball valve is difficult to meet the use requirements, so in order to improve the flow control accuracy of the existing ball valve, the present invention provides a regulating valve for fluid delivery flow control

Abstract

The invention provides a regulating valve for fluid delivery flow control. The regulating valve comprises a valve body, a valve set and a flow control unit, a valve group is arranged in the valve bodythrough a movable connection mode, and a flow control unit is arranged in the valve group in a sliding connection mode. Liquid or gas flow is difficult to control when gas or liquid flows, liquid orgas flow which is good in control causes the ball to rotate to cause the gas or liquid flow to become large when the ball is impacted to generate pressure, especially in some specific use occasions, and the gas or liquid flow controlled by the existing ball valve is difficult to meet the use requirement.

Description

technical field [0001] The invention relates to the field of valves, in particular to a regulating valve for fluid delivery flow control. Background technique [0002] Ball valve, the valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve; it can be mainly used for the regulation and control of fluid and gas. [0003] In use, the ball valve controls the relative size between the diversion hole on the ball and the through hole of the valve body by operating the valve stem, and then controls the flow rate of liquid or gas; but in the actual use process, when the gas or liquid flows The pressure caused by the through hole inside the sphere, the flow of liquid or gas is difficult to control, and the well-controlled flow of liquid or gas impacts the sphere to generate pressure, which makes the sphere rotate and the flow of gas or liquid becomes larger, especially in some specific In the application occasion, the gas ...
