Abstract

The invention provides an axial flow type rotary regulating valve. The valve includes a valve body, the valve body is internally provided with a valve chamber, one side of the valve body is provided with a feeding hole, the other side of the valve body is provided with a discharge hole, the feeding hole and the discharge hole are both communicated with the valve chamber, a flowing channel is formed between the feeding hole and the discharge hole of the valve body, the valve chamber is internally provided with a regulation mechanism, and the regulation mechanism includes a fixed plate and a rotary plate, wherein the fixed plate is in sealed connection with the inner wall of the valve chamber and the rotary plate rotates relative to the fixed plate; the fixed plate is provided with a plurality of first through holes, the rotary plate is attached to one end of the fixed plate and provided with second through holes corresponding to the first through holes, and the rotary plate rotates relative to the fixed plate so as to adjust the matching area between the second through holes and the first through holes. According to the axial flow type rotary regulating valve, a stepper motor is adopted for accurately controlling the rotation angle of the rotary plate so as to control the sectional area of medium circulation, the control is accurate, compared with the straight route, the rotary regulating valve is easier to open and close under high pressure, and the valve is small in size and convenient to install.

Description

technical field [0001] The invention relates to the technical field of regulating valves, in particular to an axial flow rotary regulating valve. Background technique [0002] Axial-flow valves are generally equipped with straight-stroke actuators. However, such valves are larger in size and take up more space; More work and higher energy consumption; under the same opening, the adjustment accuracy of the throttling groove is poor under certain conditions. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the disadvantages of large space occupation, high energy consumption and poor adjustment accuracy caused by the straight-stroke actuator structure of the valve in the prior art, the present invention provides an axial flow rotary regulating valve. [0004] The technical solution adopted by the present invention to solve the technical problem is: an axial flow rotary regulating valve, including a valve ...
