More Information
Summary:The pressure converter comprises a shell and a piston, the shell is provided with an emergency pipe nozzle, a normal pipe nozzle and an oil outlet pipe nozzle, the normal pipe nozzle is an accessory, the piston is installed in a hole cavity of the shell in a sliding mode, a sealing device is arranged on the outer diameter of the piston, and a radial sealing ring moves along with the piston and is located on one side of a through-flow hole of the oil outlet pipe nozzle. The sealing ring and the piston head serve as a sliding valve to select emergency pipe nozzle incoming oil and normal pipe nozzle incoming oil to be output by one of the pressure sources. The end face of the piston is provided with a radial groove and a circumferential notch, so that the rapidness of starting conversion is improved. The device is reasonable in structure and reliable in performance, and overcomes the defects that in the prior art, ball valves and cone valves are adopted as conversion valves, working vibration exists, conversion
