Specific embodiment
The utility model is specifically described below by embodiment.
As shown in Figure 1, present embodiment discloses a kind of flow control valve, including valve body 1, valve deck 2 and valve rod 3, valve body 1
Interior to be equipped with circulation road 11, the axis line position of circulation road 11 is equipped with shaft 4, and the first flow guiding disc 5 and the are arranged in shaft 4
Two flow guiding discs 6, the first flow guiding disc 5 are fixed in circulation road 11, and one end of the first flow guiding disc 5 has conical socket 51, the other end
For the tapered surface 52 of protrusion, the second flow guiding disc 6 equally has the tapered surface 62 of conical socket 61 and protrusion, the first flow guiding disc 5
The tapered surface of conical socket and the second flow guiding disc 6 matches, and the tapered surface of the second flow guiding disc 6 is connected to the cone of the first flow guiding disc 5
In connected in star, the second flow guiding disc 6 is rotatably installed in shaft 4, is respectively equipped on the first flow guiding disc 5 and the second flow guiding disc 6 mutually
Corresponding deflector hole 8, is arranged slow pressure impeller assembly 9 in deflector hole 8, and valve rod 3 and the second flow guiding disc 6 are sequentially connected, wherein slow
Pressing impeller assembly 9 includes mounting ring 91 and impeller 92, and the axis of mounting ring 91 is equipped with shaft 93, which passes through connecting plate
94 connect with the inner wall of mounting ring 91, and impeller 92 is set on shaft 93, and 91 outer wall of mounting ring connects with the inner wall of deflector hole 8
Touching.
8 quantity of deflector hole is for several, and best arrangement is as shown in Figure 2 along the radial direction of the first flow guiding disc 5
Arrangement and circle distribution, while the bore of deflector hole 8 is gradually increased from center to the outer peripheral surface of the first flow guiding disc 5, this
