We obtained an optical spectrum (range 390-840 nm) of SN 2016flv(= PTSS-16mvt), discovered by PMO-Tsinghua Supernova Survey (http://119.78.210.3/ptss2/), on UT Aug.28.6 2016 with the 2.16-m telescope (+BFOSC) at Xinglong Station of National Astronomical Observatories of China (NAOC). The spectrum is consistent with that of a type Ia supernovae at about one week before the maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J., 666, 1024) shows that it matches with SN 1994D at t~ -7 days from the maximum light. After correcting for a redshift of 0.053 (from the SNID fit) for its host galaxy, an expansion velocity of about 12500 km/s can be derived from the absorption minium of Si II 635.5 line.
