A hydraulic accumulator with buffer function

Abstract

The invention relates to a hydraulic accumulator with buffer function, which comprises a casing, a guide pipe is fixedly arranged at the bottom of the casing, and a sealing device is fixed at the connection between the guide pipe and the casing. The utility model includes a fixed cylinder fixed between the guide pipe and the casing, and a valve rod is vertically slidingly connected in the fixed cylinder; the guide pipe is connected with a buffer device; the buffer device includes a buffer device fixed on the guide pipe The diverter plate on the upper part, the diversion plate is provided with a diversion groove that communicates with the diversion pipe; One end of the pipe away from the diversion groove is communicated with the diversion pipe, the diversion plate is provided with a chute which is communicated with the diversion groove and the buffer groove, a baffle is slidably connected in the chute, and one end of the baffle is connected with a fluid according to the fluid. The flow pressure controls the return spring of the flap sliding. The invention has the effects of reducing the impact force of the fluid in the pipeline on the bacteria-type valve and prolonging the service life of the bacteria-type valve.

Description

technical field [0001] The present invention relates to an accumulator, in particular to a hydraulic accumulator with buffer function. Background technique [0002] Currently, an accumulator is an energy storage device in a hydropneumatic system. It converts the energy in the system into compression energy or potential energy at an appropriate time and stores it, and when the system needs it, it converts the compression energy or potential energy into hydraulic or pneumatic energy and releases it, and resupplys the system. When the pressure of the system increases instantaneously, it can absorb this part of the energy to ensure the normal pressure of the whole system. [0003] For the prior art, reference may be made to the Chinese invention application document with the application publication number CN110578719A, which discloses a buffer type accumulator, which relates to an accumulator. A capsule is arranged inside the shell, one end of the capsule is connected with the...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following disadvantages: the bottom of the shell is connected to the pipeline, when the fluid pressure in the pipeline is greater than the pressure in the capsule, the valve stem of the fungus valve is pushed upwards, so that the fluid in the pipeline enters the shell In the body, when the fluid pressure in the pipeline increases sharply, the fluid will easily damage the fungal valve, resulting in damage to the accumulator
