Abstract
The invention discloses a double-acting pressurizer special for a water pressure testing machine for steel pipes. The double-acting pressurizer comprises a pressurizer cylinder, a pressurizer cylinder cover, a base, a high-pressure cylinder, a piston, a piston sealing ring, a cylinder body connector and a fixing flange. The high-pressure cylinder is connected with the pressurizer cylinder, a high-pressure cavity in the high-pressure cylinder is connected with a waterway system, and a pressurizer cavity in the pressurizer cylinder is connected with a hydraulic system. The piston comprises a piston head and a piston connecting rod which are connected. The piston head is mounted in the pressurizer cavity, the pressurizer cavity is divided into an oil pressurizing cavity and an oil return cavity, and the piston connecting rod always extends into the high-pressure cavity. Action area ratio of the oil cavity and the water cavity is used as pressure ratio, and pressure transmission can be realized by difference of an oil inlet and an oil outlet in the oil cavity of the hydraulic system, thereby double pressure ratio is realized, and production efficiency is effectively improved by interchange of the double pressure ratio.
