A bellows-type energy accumulator used in hydraulic system of airplane or car, which has special requirement in vibration damping, shock absorbing and safety is composed of isolating body installed in casing, and the casing composed of upper half with air valve and cover and lower half. The isolating body is made up of bellows, flange and partition, which is then connected to another same one concentrically. Its advantages include wide operation temp range from-60 to 280 deg. C, absorbing vibration and shock with high effect and long service life .

Description

Membrane accumulator
The present invention relates to a kind of hydraulic accumulator that is used for stored energy, suitable especially being installed in is used to compensate oil mass and oil pressure performance in the hydraulic efficiency pressure system, the hydraulic pulsation and the load shock that attract oil pump to produce, reduce noise etc., thereby can significantly reduce the hydraulic motor desired power, especially can be used on widespread use in shockproof, as to reduce impact, safety and the own wt aircraft that specific (special) requirements arranged such as light, the auto-industry hydraulic efficiency pressure system.
The form of hydraulic accumulator is a lot, rubber capsule diaphragm type, piston type, spring loaded etc. are arranged, commonly used is that the rubber pocket diaphragm type is simple in structure, functional because of it, but because of its free body is made by rubber, temperature resistant range is little, generally between-40 ℃～90 ℃, ageing-resistant ability, if at high temperature and have work in the environment of acid then poorer.And shock resistance is poor, service life short.When free body is put into the energy storage shell, must carry out or use cold welding, its welding process requirement height, cost height at low temperatures during the upper and lower shell welding.
Application number 91100518.8 " flow through piston accumulator " has also only provided one and energy storage in the form of piston, and this piston accumulator own wt is heavy
The object of the present invention is to provide a kind of membrane accumulator, its working temperature range is greatly at-60 ℃～280 ℃, long service life, and impact resistance is good, and the shell welding can be adopted conventional heatsealing, cost-cutting.
The present invention is achieved in that membrane accumulator goes out free body and is installed in by the upper casing of gas nozzle, lid and the lower casing that has joint and connects in the integrally formed cavity, and be connected institute with the shell that connects into by upper and lower shell and constitute, described free body is linked into an integrated entity with flange, dividing plate respectively by bellows and forms; Described free body by bellows respectively with valve plate, dividing plate link into an integrated entity first free body formed again with one and more than one concentric the connecting into of another free body that connects into by bellows and flange, valve body.

Below in conjunction with accompanying drawing embodiments of the invention are further described:
There is a through hole upper and lower shell (3), (3) ', (7), (7) ' and be the cylindrical shape of arc for the bottom, weld respectively in the through hole and fix threaded valve (2) and joint (8).
Bellows (5), (13) are welded into resilient boxlike torus for the centre has through hole repeatedly to be adorned according to certain rules by corrosion-resistant steel or metal basin shape sheet.
Dividing plate (4), (4) ', valve body (12) is
Figure A9711813900041
Shape, and also have through hole in the middle of the valve body (12).
Valve plate (14) is the middle plectane that through hole is arranged
Flange (6) is the middle plectane that through hole is arranged, and last outward flange has a dovetail furrow.
Flange (10) shape and lower casing (7) ' shape is complementary, and there is a through hole centre.
Bellows (5) is welded into free body (9), (11) shown in Fig. 2,4 with dividing plate (4), flange (6) and dividing plate (4), flange (10) respectively.
Bellows (5) and dividing plate (4), (4) ' valve plate (14) is welded into first free body, bellows (13) is welded into two second free bodies with valve body (12), flange (6) and valve body (12), flange (10) respectively, then first free body is inserted in respectively in two second free bodies with one heart, and makes valve plate (14) and valve body (12) be welded into whole free body (15), (16 of forming shown in Fig. 6,8).
Free body (9), (15) are put into the cavity that is formed by upper and lower shell (3), (7) respectively, and the flange (6) on it is welded with upper and lower shell (3), (7) respectively, and also weld between the upper and lower shell (3), (7).Constitute through type, two kinds of multi-form energy storages of combined type.
Free body (11), (16) are put into by upper and lower shell (3) cavity that ', (7) ' forms respectively, and make an end and the lower casing (7) of the flange (10) on it ' through hole welding fixing, welded joint (8) and upper and lower shell (3) ' again, (7) ' between weld.Constitute through type, two kinds of multi-form energy storages of combined type again.
From the valve (2) of upper end, be pressed into the nitrogen of required compression, secure with lid (1) then, just can use.
If need this energy storage is used on the drg of automobile, can select a kind of in above-mentioned several energy storages as required, just can work as long as the joint on the energy storage (8) is connected on the brake pump of drg, automobile is after brake several times, after oil pressure reduction in the brake pump enters energy storage, oil constantly enters and promotes dividing plate (4) elongation bellows, compress the nitrogen in it, when nitrogen gas pressure increases to a certain degree, and during greater than oil pressure, just promoting dividing plate (4) compress bellows the other way around makes oily supercharging for it, final pressure oil is gone out energy storage from joint (8), reach and improve the effect that oil pressure resupplies the drg use, so constantly periodical duty.
The present invention is compared with prior art: because the slider in the accumulator adopts the metal bellows box structure, It is big to be used for separation gas and liquid so operating temperature range, can be between-60 ℃～280 ℃, and 450 ℃ of abilities High temperature ,-200 ℃ low temperature, frequency of utilization can reach more than 1,000,000 times, and acid and alkali resistance, anti-salt fog performance are greatly Improve, can under strong salt fog effect, work more than 1000 hours. Because of the big therefore absorbing performance of bellows elastic force, Shock resistance is all good, and noise is little, and can double service life, metal shell and slider welding The unrestricted thermal weld of adopting routine, so technology is simple, low cost of manufacture. Because many and different knots are arranged Structure can satisfy different needs, has enlarged the scope of application.
