But the total critical defect of existing throttle valve is that structure is loaded down with trivial details, and control is complicated, the cost height, and pipe interior flowed bigger influence.The present invention strives for adopting balanced type stressed from mechanism, improves flow passage structure, improves the Flow Field Distribution aspect and starts with, and optimizes the form of restriction, makes pressure, the flow control of throttle valve, serves execute-in-place better.
(3) summary of the invention
The object of the present invention is to provide a kind of simple in structure, easy to operate, degree of regulation height, the throttling flow control valve little, cheap to pipe interior flow field influence.
The object of the present invention is achieved like this:
The composition of restrictive flow-regulator comprises rotating ring flange, rotating ring, middle ring, vane group, base ring and base ring flange; The edge contour of blade is made of two circular arcs, straight line and two sections chamfering circular arcs that connect straight line and circular arc, and each fixes a straight pin in the both sides of the root of blade; Have the straight pin guiding groove on base ring and the middle ring; Have above the rotating ring with middle ring on the opposite straight pin guiding groove of straight pin guiding groove direction; Vane group links with base ring, middle ring and rotating ring respectively, and the rotating ring periphery has a circle straight toothed spur gear; Base ring connects with pipelines on two sides by base ring flange and rotating ring flange respectively with rotating ring.
The present invention can also comprise:
1, base ring flange one end has the pipe thread that is connected usefulness with base ring.
2, the pipe thread and one section smooth especially part that is connected usefulness with rotating ring that is connected usefulness with middle ring arranged on the rotating ring flange.
3, the bottom of middle ring and rotating ring flange has a square flanged plate.
Advantages such as throttle of the present invention has simple in structure, and is easy to operate, and the degree of regulation height is little to the influence of pipe interior flow field, and is cheap.This throttle valve applications is in pipeline, and it makes through-flow part keep circular channel constantly by changing the flow area of self, reduces the influence of stream field, thereby realizes the control to the pipe interior flow.
