Technical Field

The invention relates to a buffer type energy accumulator, and belongs to the technical field of energy storage device structures.

Background

An accumulator is an energy storage device in a hydropneumatic system. The energy in the system is converted into compression energy or potential energy to be stored at a proper time, and when the system needs the energy, the compression energy or the potential energy is converted into hydraulic energy or air pressure and the like to be released, and the energy is supplied to the system again. When the system pressure is increased instantaneously, it can absorb the energy of the part to ensure the pressure of the whole system is normal. The existing diaphragm type energy accumulator and the piston type energy accumulator can not be directly connected with a pipeline in series, and when liquid in the pipeline flows, pulsation or pulse can be generated, so that the pipeline body is easily damaged.

Disclosure of Invention

In view of the above problems, the present invention provides a buffer type energy accumulator.

The invention discloses a buffer type energy accumulator which comprises a flange, a round nut, an end cover, a cylinder body, an inner pipe, an inflation valve, a rubber cylinder, a check ring and an O-shaped ring.

Preferably, the cavity between the rubber cylinder and the cylinder body is filled with nitrogen.

Preferably, the side wall of the inner pipe is provided with a plurality of feeding holes.

Preferably, the check ring is SB1 type, and the check ring is made of polytetrafluoroethylene material.

Preferably, the rubber cylinder and the O-shaped ring are both made of nitrile rubber.

The invention has the beneficial effects that: the device has simple structure and reasonable design, is directly arranged on the pipeline and is communicated with the straight-through pipeline in series, and liquid enters the liquid cavity of the drawing buffer through the small hole on the side wall of the inner pipe to extrude the nitrogen in the air cavity, thereby achieving the effect of absorbing pulsation and pulse.
