Abstract

One or more embodiments of the invention provide a hydraulic pressure relief device and method. The hydraulic pressure relief device comprises a cartridge valve and a control unit; the cartridge valve is arranged on an oil pipe connected with an oil tank; the cartridge valve is provided with an oil inlet, an oil outlet and a control cavity; a control piston capable of sliding is arranged in the control cavity, and the control cavity is connected with the control unit; and the control unit is configured to detect the pressure intensity of fluid in the oil pipe through connection with the oil pipe so as to control sliding of the control piston in the control cavity and control a communication state of the oil inlet and the oil outlet. One or more embodiments of the invention detect the fluid pressure in the oil pipe through the control unit, control the communication state of the oil pipe through the cartridge valve according to the pressure, reduce an opening of the oil pipe flowing to the oil tank when the fluid pressure in the oil pipe is high, release pressure stably, increase the opening of the oil pipe flowing to the oil tank after the fluid pressure in the oil pipe is reduced, and release pressure quickly, therefore, the pressure relief efficiency is ensured while the device and operators are protected, and the effects of increasing the speed and efficiency are achieved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of hydraulic control, and in particular to a hydraulic pressure relief device and method. Background technique [0002] With the rapid development of social production level and the development of hydraulic forging equipment, the production speed and efficiency of hydraulic forging equipment have become a hot research direction. However, while the speed of the equipment is increasing, a new problem is exposed to everyone. Various hydraulic actuators operate under high frequency and high pressure, and the problem of load leakage when the equipment performs one action and turns to the next action has become a new concern. point. If the load is not released and the next process is carried out directly, the moment the high-pressure valve is directly opened will generate huge vibration and impact, which will have a great impact on the life of the equipment, the production of the wo...
