Valve capable of regulating pressure drop

The invention provides a valve capable of regulating pressure drop and belongs to the field of valves. The valve comprises a valve body, a sleeve, a sliding plate, a valve rod, a sliding plate rod, a sleeve support, a valve rod positioning base and a sliding plate rod support. The valve rod is in linkage connection with a sliding plate rod in the valve body, the sliding plate rod drives the sliding plate to perform piston motion in the sleeve along the axial direction of the valve, and holes are arranged on the side wall of the sleeve and the sliding plate according to a certain rule. The valve capable of regulating the pressure drop overcomes the defect that when an existing typical valve is operated, medium in a pipe is easy to form turbulence so as to lead a pipe system to vibrate, operation torsion is large, and regulation is inflexible, is small in operation torque, and regulates flexibility of regulation medium pressure and flow.
