Sleeve Regulating Valve

Sleeve regulating valve refers to a dual valve core structure with a valve disc on the inside and a sleeve on the outside of the regulating valve. The working principle of sleeve regulating valve is based on its special valve core structure. The gap between the sleeve and the valve disc is matched, and there are multiple throttling windows on the sleeve. The shape and area of the windows determine the flow characteristics of the regulating valve. The valve seat adopts a self centering non threaded clamping structure, and the conical sealing surface on the valve seat cooperates with the conical sealing surface on the valve disc to form a cut-off sealing pair, ensuring the sealing performance of the valve when it is tightly closed. There are symmetrically distributed balance holes parallel to the axial direction on the valve disc, which connect the chambers on the upper and lower end faces of the valve disc. Most of them cancel out the force of the medium acting on the axial direction of the valve disc, thereby reducing the unbalanced force generated by the medium on the valve stem. The large guide surface of the valve core reduces the oscillation caused by eddy currents and impacts.
