The invention discloses a high-pressure water injection and steam injection manual stopping adjusting valve for an oil field. A cylinder sleeve is arranged in a valve body, a valve clack is installedin an inner cavity of the cylinder sleeve and is in sliding fit with the inner wall of the inner cavity, and first horizontal through holes are formed in the bottom of the cylinder sleeve; and a flowguiding sleeve is arranged at the joint of an upper flowing channel and a lower flowing channel, a valve seat is arranged at the bottom of a clearance space formed between the flow guiding sleeve andthe cylinder sleeve, and the sealing face of the valve clack is set as an outer conical sealing face. Direct scouring of a high-pressure high-speed medium on the sealing face of the valve clack and the sealing face of the valve seat in the valve opening, closing and adjusting process is avoided, and the valve clack sealing face and the valve seat sealing face are protected; and in addition, a self-flushing structure is formed between the clearance space and the side walls of the flow guiding sleeve and the cylinder sleeve which are located on the two sides of the clearance space as well as between the clearance space and the side wall of the valve clack, when the valve clack is closed to be in place, particular impurities such as fine sand in the clearance space can be self-flushed out through a medium, and the condition that particles or sundries precipitate at the low concave portion or the sealing faces are damaged when the valve clack is closed is avoided.
