Description

Buffer type energy accumulator

Technical Field

The invention relates to an energy accumulator, in particular to a buffer type energy accumulator.

Background

An accumulator is a device designed specifically for accumulating pressurized fluids that are incompressible in use, taking advantage of the compressibility of gases to achieve the goal of storing energy. 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 traditional bag type energy accumulator has a short service life due to poor buffering effect, and the maintenance and replacement cost of equipment is increased.

In summary, the invention provides a buffer type energy accumulator.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a buffer type energy accumulator which is reasonable in structural design, good in buffer effect, low in maintenance and replacement cost and strong in practicability, and the service life of the energy accumulator is greatly prolonged.

In order to achieve the purpose, the invention is realized by the following technical scheme: the buffer type energy accumulator comprises a protective cap, a heavy type inflation valve, an air valve rod, a capsule, a round nut, a nameplate, a shell, a bacterial type valve, a spring, a flow valve body, a supporting ring, a rubber ring, a metal retainer ring and an O-shaped ring, the pneumatic valve comprises a F4 check ring, a pressing ring, a lock nut, a screw plug, a piston, a flat gasket, a disc spring and a self-locking nut, wherein a capsule is arranged inside a shell, one end of the capsule is connected with a heavy inflation valve through a gas valve rod, a protective cap is arranged outside the gas valve rod, the outside of the gas valve rod is fixed with one end of the shell through the circular nut, a nameplate is further arranged between the circular nut and the shell, the other end of the shell is fixed with a valve body through a supporting ring, a rubber ring, a metal check ring, an O-shaped ring, an F4 check ring, a pressing ring, the lock nut and the valve body, the piston is penetrated in the middle of the valve body, the inner end of the piston is provided with the.

the invention has the beneficial effects that: structural design is reasonable, and buffering effect is good, has improved the life of energy storage ware greatly, maintains and replacement cost is low, and the practicality is strong.

Drawings

The invention is described in detail below with reference to the drawings and the detailed description;

FIG. 1 is a schematic structural diagram of the present invention.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the buffer type energy accumulator comprises a protective cap 1, a heavy duty inflation valve 2, a gas valve rod 3, a capsule 4, a round nut 5, a nameplate 6, a shell 7, a bacterial valve 8, a spring 9, a flow valve body 10, a supporting ring 11, a rubber ring 12, a metal retainer ring 13, an O-shaped ring 14, an F4 retainer ring 15, a pressing ring 16, a locking nut 17, a screw plug 18, a piston 19, a flat gasket 20, a disc spring 21 and a self-locking nut 22, wherein the capsule 4 is arranged inside the shell 7, one end of the capsule 4 is connected with the heavy duty inflation valve 2 through the gas valve rod 3, the protective cap 1 is arranged outside the gas valve rod 3, the outer part of the gas valve rod 3 is fixed with one end of the shell 7 through the round nut 5, the nameplate 6 is further arranged between the round nut 5 and the shell 7, the other end of the shell 7 is fixed with the flow valve body 10 through the supporting ring 11, the rubber ring 12, the metal retainer ring 13, the, the inner end of the piston 19 is provided with a bacterial valve 8, the outside of the bacterial valve 8 is also provided with a spring 9, the outside of the piston 19 is provided with a disc spring 21, and the outer end of the piston 19 is connected with a self-locking nut 22 through a flat gasket 20.

The mushroom valve 8 of this embodiment prevents the capsule from being squeezed into the fluid port while allowing free flow of liquid. The spring and the piston 19 on the bacterial valve 8 play a role in buffering, so that liquid can slowly flow back to the oil storage tank, the service life of the energy accumulator is greatly prolonged, the maintenance and replacement cost is reduced, and the practicability is high.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
