The invention provides a butterfly valve with an adjustable inner bypass self. The butterfly valve comprises a butterfly valve body; the interior of the butterfly valve body is divided into two regions including a valve body inner cavity A and a valve body inner cavity B; a valve seat of the valve body inner cavity A is provided with a butterfly plate A in a matching manner; a valve seat of the valve body inner cavity B is provided with a butterfly plate B in the matching manner; the butterfly plate A is connected with a valve rod A; the butterfly plate B is connected with a valve rod B; the valve rod A and the valve rod B are arranged in a nested manner; and the valve rod A rotates in the valve rod B to realize adjustment of an opening degree of the butterfly valve. For a provided novel butterfly valve structure with the inner bypass adjusting characteristic self, a special valve rod form is controlled through two different sets of executing mechanisms, and flow linear adjustment of the butterfly valve under a small opening degree can be realized. The device is simple in structure and reliable in performance and is suitable for wide-range popularization and use.
