Abstract

The invention relates to a hydraulic cylinder, and provides an integrated hydraulic cylinder having a bidirectional pressure safety protection function. The integrated hydraulic cylinder is used for achieving bidirectional hydraulic medium pressure safety protection from any cavity to the other cavity of the hydraulic cylinder on the basis of achieving basic functions of the hydraulic cylinder in a narrow space. The integrated hydraulic cylinder is composed of a cylinder body, a large end cover, a piston with a piston rod, a guide sleeve, a sealing component, a safety valve, a stop valve and a pipeline. The safety valve is composed of a large lock nut, an end cover, a pilot valve and a main valve. The stop valve is composed of a lock nut, a valve body and a valve element. The safety valve and the stop valve are integrated in the cylinder body of the hydraulic cylinder. According to the integrated hydraulic cylinder, the safety valve and the stop valve are integrated, so that multiple functions are added under the condition that the size of the hydraulic cylinder is basically not increased. The integrated hydraulic cylinder has the characteristics of being rich in function, compact in structure, high in integration level and the like.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a hydraulic component, in particular to an integrated hydraulic cylinder with bidirectional pressure safety protection. Background technique [0002] A hydraulic cylinder refers to a hydraulic actuator that converts the pressure energy of the working medium into the mechanical energy for the movement of the piston rod of the hydraulic cylinder in hydraulic transmission. The hydraulic cylinder is simple in structure and reliable in operation, and has been widely used in hydraulic systems. [0003] The function of the existing hydraulic cylinder is relatively simple, only converting hydraulic energy into mechanical energy. To realize the two-way hydraulic medium pressure safety protection from any cavity of the hydraulic cylinder to the other cavity, it is necessary to install a safety valve in the hydraulic system, which will make the hydraulic pressure The system is complex, the number of ...
