Description of reference numerals:

the valve comprises a valve body 1, a valve core 2, a discharge channel 2-1, a diversion trench 2-2, a pneumatic motor mounting flange 3, a pneumatic motor 4, a feed inlet 5, a support column 6, a first discharge port 7, a coupling 8 and a second discharge port 9.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 8, the following technical solutions are adopted in the present embodiment: the pneumatic valve comprises a valve body 1, a valve core 2, a pneumatic motor mounting flange 3, a pneumatic motor 4, a feeding hole 5, a support 6, a first discharging hole 7, a coupling 8 and a second discharging hole 9; a valve core 2 is arranged in the valve body 1, an upper end shaft of the valve core 2 is connected with an output shaft of a 90-degree pneumatic motor 4 through a coupling 8 (the coupling 8 is clamped and fixed with the output shaft and the upper end shaft through bolts), the pneumatic motor 4 is erected and locked and fixed on a pneumatic motor mounting flange 3 through screw shrinkage, and the pneumatic motor mounting flange 3 is fixed on the upper part of the valve body 1 through a support 6 (after the bolts penetrate through the pneumatic motor mounting flange 3 and the support 6, the bolts are in threaded connection in threaded holes in the valve body 1); a feed inlet 5, a first discharge port 7 and a second discharge port 9 are communicated and welded on the annular wall of the valve body 1, and the first discharge port 7 and the second discharge port 9 are arranged in axial symmetry relative to the feed inlet 5; a discharge channel 2-1 is arranged in the valve core 2, and the discharge channel 2-1 is communicated with a first discharge port 7 and a second discharge port 9 respectively; a flow guide groove 2-2 which is communicated with the discharge channel 2-1 and has an opening angle of 120 degrees is arranged on the valve core 2 at the inner end position of the discharge channel 2-1, the flow guide groove 2-2 and the feed inlet 5 are correspondingly communicated, and the first discharge port 7 and the second discharge port 9 are in threaded connection with an input pipeline of the crystallizer; the inner diameters of the feed inlet 5, the first discharge hole 7 and the second discharge hole 9 are all 26 mm.
