In this embodiment, the through outlet 302 is preferably a through outlet communicated with the inlet 301; the vertical discharge hole 303 is preferably a discharge hole vertical to the feed hole 301; when the material is required to be conveyed directly, the feed port 301 is communicated to the direct feed port 302 through the valve core direct pipe 503, as shown in fig. 1; when the included angle of the material conveying pipeline needs to be switched to 90 degrees, the feed port 301 is communicated to the vertical discharge port 303 through the valve core baffle 505, as shown in fig. 3; the switching between the two states can be realized only by driving the valve core 5 to move up and down through the piston rod 101 of the hexagonal non-rotating cylinder 1.
As shown in fig. 1 to 5, in this embodiment, the spool baffle 505 is an inclined baffle, and the inclined baffle is obliquely connected to the vertical discharge port 303 from the feed port 301; the valve core straight-through pipe 503 is parallel to the direction between the feed inlet 301 and the straight-through discharge outlet 302. As shown in fig. 1 and fig. 3, the valve body 3 of this embodiment includes a limit pin 304, the limit pin 304 is disposed at an inner side of the valve body 3 close to the feed port 301, and is disposed below the feed port 301, for limiting the valve element through pipe 503, and correspondingly, a limit pin notch 305 for accommodating the limit pin 304 is disposed at a side of the valve element baffle 505 close to the feed port 301, so as to facilitate the implementation of the position limiting function of the limit pin 304.
As shown in fig. 1 and fig. 3, in this embodiment, the limiting pin 304 is further disposed at the inner side of the valve body 3 close to the through outlet 302 and below the through outlet 302, so as to further ensure the stability of the position-limiting function.
