The invention discloses an abutting-locking type butterfly valve. The abutting-locking type butterfly valve comprises a valve body, a valve plate, a connection sleeve, a drive rod, a telescopic assembly and an abutting screw rod; the bottom of the connection sleeve is provided with a threaded channel; and the abutting screw rod penetrates through the threaded channel at the bottom of the connection sleeve in a threaded mode to abut against the lower end of a positioning block. According to the abutting-locking type butterfly valve, as the abutting screw rod can penetrate through the threaded channel at the bottom of the connection sleeve in the threaded mode to abut against the lower end of the positioning block, the positioning block can be connected with the connection sleeve more firmlyin the longitudinal space, the positioning block can be positioned in the longitudinal direction, and thus a telescopic barrel and the connection sleeve can be more firmly connected in a clamped mode.
