Abstract

The utility model discloses a granular solid material flow rate controller which comprises an upper valve body and a lower valve body which are connected to form a middle cavity, wherein a feed port runner and a feed port runner respectively penetrate through the upper valve body and the lower valve body and are connected to the middle cavity, a bearing plate with a preset distance from the lower port of the feed port runner is arranged in the middle cavity and is fixed through a torsion arm, a valve rod penetrating through the upper valve body is connected with the torsion arm, a valve actuator is arranged at the upper part of the valve rod, and a packing group is arranged on the outer side wall of the valve rod. Thereby avoid interior surface and bushing pipe metal material pollution product that the material flows through and cavity interior component material supporting disk too big lead to torsion arm rotation angle little lead to automatic control procedure configuration check-up difficulty, avoid the cavity interior component material supporting disk sunken edge angle to steep and lead to the granule gathering to take place frequent card to be put on, the cavity is in the technical problem that the connecting device of support tray and torsion arm is easy not hard up to drop and causes there is foreign matter and pollution in the product package.
