Problems solved by technology

[0003] However, it is not uncommon for equipment to shut down due to failure of hydraulic cylinders.
Due to external factors such as aging and wear, the pipeline is prone to rupture under long-term external wind and rain, resulting in an unbalanced pressure difference between the inside and outside of the cylinder, thereby damaging the cylinder and causing the power arm or heavy load it drives to lose balance , resulting in major safety accidents

Abstract

The invention discloses a combined oil cylinder anti-explosion valve assembly. The combined oil cylinder anti-explosion valve assembly comprises two oil paths; and each oil path comprises an oil cylinder, an explosion-proof valve, a plate-type ball valve, a pressure measuring joint, a pressure gauge, a pressure gauge switch, an overflow valve, a ball valve, a one-way valve, an explosion-proof valve, a plate ball valve, a pressure measuring joint, a pressure gauge, a pressure gauge switch, an overflow valve, a ball valve and a one-way valve, wherein the anti-explosion valve set is arranged on the cylinder side valve block. Under the normal condition, oil can quickly pass through the explosion-proof valve bank, and meanwhile, the pressure gauge of the cylinder side valve block monitors the oil way pressure in real time, so that a good preventive effect can be achieved for the emergency situation; the internal pressure can be adjusted in the maintenance process, so that the internal pressure and the pressure difference of the system under the normal working state are achieved; and meanwhile, when an oil cylinder breaks down, the ball valve and the one-way valve can provide safety guarantee for overhauling, the overflow valve in the assembly can also play a good pressure maintaining effect, the oil cylinder can run stably, and the service life of the oil cylinder is guaranteed.

Description

technical field [0001] The invention discloses a combined oil cylinder explosion-proof valve assembly and relates to the field of oil cylinder safety design. Background technique [0002] The hydraulic cylinder is the actuator in the hydraulic transmission system, and it is an energy conversion device that converts hydraulic energy into mechanical energy. Hydraulic cylinders realize reciprocating motion. The hydraulic cylinder is simple in structure and reliable in operation, and has been widely used in the hydraulic system of machine tools. [0003] However, it is not uncommon for equipment to stop due to failure of hydraulic cylinders. Due to external factors such as aging and wear, the pipeline is prone to rupture under long-term external wind and rain, resulting in an unbalanced pressure difference between the inside and outside of the cylinder, thereby damaging the cylinder and causing the power arm or heavy load it drives to lose balance , resulting in major safety ...
