Technical Field

The invention relates to the technical field of energy accumulators, in particular to a mesh type oil valve body low-pressure bag 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.

When the liquid inlet flow of the conventional bag type energy accumulator is large, a rod of the bacterial valve is easily broken or a thread is cut off, so that the bacterial valve enters the energy accumulator, and a leather bag is burst, thereby damaging the energy accumulator.

In conclusion, the invention designs the mesh type oil valve body low-pressure bag type energy accumulator.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide the mesh screen type oil valve body low-pressure bag type energy accumulator which is reasonable in structural design, and ensures that a capsule cannot be broken under the working pressure of less than or equal to 3.5MPa by using a special mesh screen type oil valve body.

In order to achieve the purpose, the invention is realized by the following technical scheme: the mesh-type oil valve body low-pressure bag type energy accumulator comprises a protective cap, an inflation valve, a sealing device, a shell, a capsule and a mesh-type oil valve body, wherein the capsule is arranged inside the shell, the open end of the capsule is connected with the inflation valve, the inflation valve is in sealing connection with one end of the shell through the sealing device, the protective cap is arranged outside the inflation valve, and the other end of the shell is fixedly connected with the mesh-type oil valve body.

Preferably, the mesh screen structure is arranged at the inner end of the mesh screen type oil valve body.

The invention has the beneficial effects that:

Compared with the traditional oil valve body, the oil valve body has the advantages that internal parts such as the bacterial valve, the spring, the piston and the self-locking nut are removed, the internal structure of the oil valve body is simplified, and the processing cost is reduced; and the capsules can not be broken under the working pressure less than or equal to 3.5MPa, so that the service life of the energy accumulator is greatly prolonged.

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: mesh formula oil valve body low pressure bag formula energy storage ware, including protective cap 1, inflation valve 2, sealing device 3, casing 4, capsule 5 and mesh formula oil valve body 6, the inside capsule 5 that is provided with of casing 4, the open end and the inflation valve 2 of capsule 5 are connected, inflation valve 2 passes through sealing device 3 and 4 one end sealing connection of casing, 2 outsides of inflation valve are provided with protective cap 1, 4 other ends of casing and 6 fixed connection of mesh formula oil valve body.

It is worth mentioning that the inner end of the mesh screen type oil valve body 6 is provided with a mesh screen structure.

This embodiment is through setting up mesh screen formula oil valve body 6 in energy storage ware one end for the energy storage ware can not break the capsule when the feed liquor flow is big, has guaranteed the normal operating of energy storage ware, compares with the tradition, has got rid of inside part fungus type valve, spring, piston, self-locking nut, and oil valve body inner structure simplifies, reduces the processing cost.

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.
