Detailed description of the invention
This utility model specifically discloses a kind of opaque material sampling vacuum valve, shown in Fig. 1, Fig. 2, described valve
Door is arranged at raw material processing device bottom.
Including a valve body 1, the rotatable logical powder axle 2 that is placed in valve body 1.Described logical powder axle 2 bottom stretches out formation
One protrude bottom 23, described bottom 23 diameter be more than described logical powder axle 2 upper diameter.
Described logical powder axle 2 upper end offers the logical powder hole 21 of one and raw material processing equipment UNICOM, the side of described logical powder axle 2
Offering a linked hole 22 being connected with logical powder hole 21, described linked hole 22 is vertical with described logical powder hole 21 axis.In order to more preferably
Carrying out take powder, described logical powder hole 21 is coaxial with described logical powder axle 2.
Described valve body 1 is connected with described raw material processing equipment by valve body connector 3.Described valve body 1 and valve body connector 3
Between be bolted to connection, in order to regulate the position of logical powder axle 2, between described logical powder axle 2 and valve body connector 3, pass through spiral shell
Bolt 7 connects.The side of described valve body 1 offers one and leads to powder axle 2 with the storage tank connected valve outlet of powder 11, rotation, drives described
The logical relative valve body 1 of powder axle 2 moves up and down, and makes to carry out UNICOM and close between described linked hole 22 and described valve outlet 11
The conversion closed.Concrete, when the length of described logical powder axle 2 is more than described valve body 1 length, and described linked hole 22 and described valve body
During outlet 11 not UNICOM, the upper end of described logical powder axle 2 is higher than described valve body connector upper surface.When described linked hole 22 and institute
When stating valve outlet 11 UNICOM, the upper end of described logical powder axle 2 is with the upper surface of described valve body connector at grade.Powder
