The invention discloses a mass-flow quick-opening cylindrical valve without external energy source drive and belongs to the valve field. The mass-flow quick-opening cylindrical valve without external energy source drive comprises a cylindrical valve body and a Chinese character Shi-shaped valve core, the inside of the cylindrical valve body is a stepped hole, the valve core is arranged in the valve body, matched with the stepped hole and capable of sliding in the stepped hole, the valve body comprises a communicated liquid inlet cavity and a control cavity of which the inner diameter is larger than the inner diameter of the liquid inlet cavity, the valve core comprises a throttle post and a guide post connected by a connecting bar and respectively matched with the liquid inlet cavity and the control cavity in a sealing mode, a fluid outlet is formed in the cavity wall of the control cavity near the junction of the liquid inlet cavity and control cavity, and a switch for regulating the slide of the valve core along the axial direction of the valve body is arranged at the end of the valve core connecting bar on the control cavity. The mass-flow quick-opening cylindrical valve without external energy source drive provides high flow, the starting and stopping are fast to realize, the external energy source drive is not needed, and the energy is saved.
