POROSITY-TYPE ROTARY VALVE

摘要

The present invention is a technique related to a porous deformation valve using a bevel gear with a simple and firm structure since a stem and a disk are engaged through a bevel gear. The porous deformation valve comprises: a valve body having an inner flow passage penetrating the same; a first disk having a plurality of penetrated first disk holes to be fixated to the inside of the valve body; a second disk having a second disk hole penetrated to correspond to the first disk hole and coupled to be rotated to a front side of the first disk to enable a position of the second disk hole to be matched to the first disk hole when the second disk is rotated; and the stem engaged with the second disk through the bevel gear formed on one side thereof to provide a rotational force to the second disk.
