Detailed Description

In order to enable those skilled in the art to better understand the present utility model, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in figures 1-3, the proportional regulating flow valve comprises a valve body 10, a valve cavity 16 is arranged in the valve body 10, two threaded joints are arranged on the periphery side of the valve body 10, the upper end face of the valve body 10 is rotationally connected with a valve rod 11, a knob 12 is arranged on the valve rod 11, a valve core assembly is arranged in the valve body 10 and comprises a valve core 18 positioned in the valve body 10, a connecting rod 19 is fixedly connected with one side end face of the valve core 18, the connecting rod 19 extends into the valve rod 11, the connecting rod 19 is in square arrangement and is in sliding connection with the valve rod 11, the valve rod 11 can be driven to rotate when the valve core 18 slides to any position through the arrangement of the square connecting rod 19, the end face of the other side of the valve core 18 is rotationally connected with a rotary rod 17, at least two valve holes 20 are radially arranged in the valve core 18, and the radius of the valve holes 20 is increased up and down proportionally.

The lower extreme periphery side threaded connection of valve body 10 has regulation lid 13, and rotary rod 17 outwards extends to and is fixed with regulation lid 13, and the periphery side of regulation lid 13 has still seted up anti-skidding recess, and the periphery side rotation of regulation lid 13 is connected with rotor ring 14, and two spouts have been seted up to the periphery side of valve body 10, are equipped with slide bar 15 in every spout, and slide bar 15 is L shape setting, and slide bar 15 is together fixed with rotor ring 14, and the surface of slide bar 15 is equipped with the sign, and the sign corresponds with the center of valve opening 20.
