The invention discloses a gasbag-type energy accumulator which comprises a shell, an inner cavity, a gasbag, a buffer frame, a liquid flow control device, a liquid flow circulation device and a spring set, wherein the interior of the shell is the inner cavity; the gasbag is placed in the inner cavity; the gasbag is connected to a connecting end via a gas inlet pipe; the buffer frame, the liquid flow control device and the liquid flow circulation device are arranged at the lower end of the inner cavity; the buffer frame and the liquid flow circulation device are connected into a whole; the spring set is perpendicularly arranged at the lower ends of the buffer frame and the liquid flow circulation device to correspond to the buffer frame and the liquid flow circulation device; and the bottom end of the shell is connected to a liquid flow pipe via a connecting shell. For the gasbag-type energy accumulator, the structure thereof is changed by combining a common gasbag-type energy accumulator used now, branching processing is performed on the gas inlet pipe structure of externally added gas, in addition, the buffer structure of the bottom end is designed by adopting the structure of the spring set, and moreover, the liquid flow control device is arranged, so that the pressure intensity of the inner cavity is reasonably controlled and the practicality is improved.
Description
technical field [0001] The invention relates to the technical field of accumulator devices, in particular to an airbag type accumulator. Background technique [0002] The bladder accumulator is a bladder accumulator developed by utilizing the compressibility of gas (nitrogen), which is a device for accumulating hydraulic oil. The bladder type accumulator is composed of an oil part and a gas part with an air seal, and the oil around the bladder is connected to the oil circuit. When the pressure rises, the oil enters the accumulator, and the gas is compressed until the system pipeline pressure no longer rises; when the pipeline pressure drops, the compressed air expands, and the oil is hydraulically injected into the circuit, thereby slowing down the decrease of the pipeline pressure. [0003] However, the structure of the existing airbag accumulator is relatively simple. The pressure of the entire inner cavity is controlled by the buffer spring, so that the pressure of the s...
