Description

Energy storage ware structure of easy dismouting

Technical Field

The utility model relates to an energy accumulator structure improvement, in particular to an energy accumulator structure easy to assemble and disassemble, and belongs to the technical field of energy accumulators.

Background

The capsule accumulator is a device for storing and releasing hydraulic pressure to store energy, stabilize pressure, eliminate pulsation, absorb impact, compensate capacity and compensate leakage by utilizing the compressibility of gas in the capsule. The traditional bag type energy accumulator is provided with a large opening end on the shell 1 for facilitating the disassembly and assembly of internal parts such as capsules, and the capsules 2 are disassembled and assembled to enter and exit from the large opening end. The size of the internal part of the energy accumulator must consider the size limit of the large opening end, and the internal part which is larger than the size of the large opening end must consider adopting a detachable structure. The conventional bladder accumulator structure is shown in fig. 1. The sealing of the large opening end of the energy accumulator is realized by compressing the compression ring 4 through the locking nut 3 to deform the O-shaped sealing ring 5, so that the purpose of radial sealing is achieved. The positioning snap ring 6 has the appearance size larger than that of the large opening end, and adopts a two-piece split structure and is glued with the integral rubber support ring 7 for facilitating the entering and exiting of the large opening end of the shell, and the two-piece structure is oppositely pinched and deformed during disassembly and assembly and then enters and exits from the large opening end. The structure has the advantages of more parts, complex structure and difficult disassembly and assembly; the contact surface of the positioning snap ring 6 with the shell 1 and the valve seat 8 is narrow, and the positioning performance is poor; the rubber ring 7 is easy to fall off, and the capsule 2 loses protection, thus being easy to cause capsule rupture. The locking of the set nut 10 for the protection valve 9 uses a split pin which needs to be assembled through a radial hole in the valve seat 8, reducing the strength of the valve seat 8 and increasing the leakage points. The outer end of the valve seat 8 is connected with a flange 11 in a threaded mode, and then a mating flange 12 is fixedly connected with the flange 11 through bolts 13. Like this, the whole weight of energy storage ware is born by disk seat 8, and poor stability especially when equipment or the operating mode use that the pulse is big, the vibration is high, easily causes faults such as snap ring pine, sealed inefficacy.
