key word:



As the main components of the Christmas tree and manifold, the throttle valve is mainly used to control the flow of medium at the wellhead. The throttle valve is divided into two types: adjustable throttle valve and fixed throttle valve. The adjustable throttle valve adjusts the opening area of the throttle nozzle by turning the handwheel to drive the stem forward and backward to achieve the purpose of controlling and adjusting flow . The fixed type; the flow valve changes the cross-sectional size of the flow channel by replacing the throttle oil nozzles with different apertures to achieve flow control.
