The low-pressure energy storage device comprises a shell; the upper part of an inner cavity of the shell is provided with a sealed capsule; the top end and the bottom end of the shell are respectively provided with through holes; the top end of the capsule is provided with a gas inlet connected with a gas inflating valve; the lower end of the shell is connected with an oil outlet valve body; and the shell is formed by welding a cylinder body and seal heads at two ends of the cylinder body. Because the shell of the energy storage device is formed by welding the cylinder body and the seal heads at two ends, and the cylinder body in the middle is coiled and welded by stainless steel, so that the low-pressure energy storage device is customized according to requirement of customers, and the problem that an existing energy storage device is insufficient in volume is solved.
Description
Technical field
The utility model relates to the accumulator technical field, particularly a kind of low pressure accumulator that is more suitable for use under environment under low pressure.
Background technique
At present, along with rapid development of science and technology, every profession and trade (oil, chemical industry, space flight, exploitation) also constantly increase the demand of hydraulic system, the hydraulic equipment role is particularly important, the auxiliary grade of hydraulic pressure Related product also produces thereupon and is widely used, and presents the good situation that specification is many, kind is complete, standardization level is higher especially.
Accumulator is a requisite vitals in the hydraulic system in the hydraulic pressure subsidiary products.Accumulator can store excess energy in the hydraulic system, and discharges when hydraulic work system again, both can reduce pulsation, reduce noise, can save a large amount of energy again.Can have some defectives of existence on the accumulator structure now, the first, product demand is increasing more reliably to the big discharge capacity of low pressure, stability for the International Industry depth development.But domestic voltage stabilizing product volume is mainly 0.4 and rises to 200 liters, can only adopt when surpassing 200 liters many parallel connections, so not only take up room big, efficient is low, cost is high but also brought inconvenience to maintenance.So this respect product can only dependence on import, but also there are a lot of shortcomings in import voltage stabilizing product: as involve great expense, supply cycle is long and the poor compatibility of homemade corresponding product etc.The second, the accumulator oil outlet end is bad because of the cone valve sealing effect, and system often produces pressure gos up, and manifests more obvious in low service system, brings influence to system stability.The 3rd, built-in capsule is because of the tired explosion of alternating shear stress of bottom contact cone valve, and the life-span reduces.The 4th, the sealing of oil-feed lower end damages easily, and handy hanging device is put in order product and hung out during replacing, makes troubles to replacing.Brought many unfavorable factors for like this industry developments such as domestic petroleum, chemical industry, space flight, exploitation.This just is badly in need of inventing a kind of above-mentioned defective that overcomes, the more preferably accumulator of hydraulic pressure industry service.
Summary of the invention
The purpose of this utility model be to provide that a kind of volume is big, good sealing effect, low pressure accumulator easy to maintenance.
The purpose of this utility model is achieved in that
This low pressure accumulator, comprise housing, on housing inner chamber top Packed capsule is set, housing top and bottom respectively are shaped on through hole, described capsule top is provided with suction port, suction port connects gas charging valve, and described housing lower end connects the oil outlet valve body, and described housing is welded by the end socket at cylindrical shell and cylindrical shell two ends;
Described cylindrical shell is to adopt steel plate to roll to be welded;
Described oil outlet valve body is divided into outer valve body and the valve block of connecting, and described valve block welds with the housing lower end, valve block with connect valve body outward and be threaded;
Be welded with the Oil Guide orifice plate in described housing lower end valve block upper end, be shaped on a plurality of turnover oilholes on the Oil Guide orifice plate.
The utlity model has following advantage:
1. because this product shell is a end socket by cylindrical shell and two ends is welded, middle cylindrical shell rolls welding by stainless steel, can customize according to client's actual demand like this, has solved the not enough problem of existing accumulator volume.
2. the oil inlet and outlet cone valve changes orifice plate into from motive sealing.Fluid directly frees in and out the fluctuation of having avoided fluid by oil guiding hole makes fluid mobile more stable.When the built-in capsule of product promoted fluid and discharges, capsule acted directly on and directly cuts off oil circuit on the orifice plate, made the fluid in the cylindrical shell can not secondary back, and the pressure of having eliminated system simultaneously gos up and the unstable phenomenon of pressure.
3. the oil inlet and outlet valve body adopts two bodies to connect, and makes the outer replacing that connects valve body change more convenient.
4. the bottom of the built-in capsule of product adopts special processing to carry out uniform thickened, makes the capsule bottom have very high intensity and toughness.Improved the working life of built-in capsule greatly.
5. the top of product adopts flange vertical fixing formula to install, and makes dismounting convenient, and it is more reasonable to lift.
6. valve block adopts and the housing welded structure, has reduced leak site, has avoided the product lower end that the rapid wear sealing is arranged like this and causes leakage, and large-scale hanging device enters when having stopped maintenance.
