Abstract
The utility model discloses a straight diaphragm accumulator product overcoming defects that existing similar products are not suitable for manufacturing models with large capacity and easy to leak. The straight diaphragm accumulator consists of a steel cylinder, a pneumatic interface, a hydraulic interface, wherein the pneumatic interface provided with a valve is welded on upper end necking parts of the steel cylinder, the hydraulic interface is welded on lower end necking parts of the steel cylinder, a dirt-proof cap is arranged on the surface of the valve, an elastic diaphragm installed in the inner cavity of the steel cylinder separates the inner cavity into an upper gas chamber and a lower fluid chamber, open end of the elastic diaphragm is fixed on inner wall of the steel cylinder adjacent to the upper end necking parts of the steel cylinder through a metal locking ring, and a closing lid is nested in center of the bottom of the elastic diaphragm, a pair of arch-shaped convexes are arranged on the open end of the elastic diaphragm, and the metal locking ring is nested between the two arch-shaped convexes. The straight diaphragm accumulator has a good sealing performance, a large energy storage capacity and a wide applicable range, and meets application requirements of different hydraulic environments including navigation, metallurgy, military project, railway, and mining.
Description
Technical field
The utility model relates to a kind of being connected in the hydraulic system, mainly plays the diaphragm accumulator product manufacturing technology of auxiliary energy-storage, noise reduction and pooling feature, especially refers to housing and the elastic diaphragm assembly structure technology of accumulator.
Background technique
Accumulator is a kind of at the inner auxiliary device that plays accumulation of energy, noise reduction and pooling feature of hydraulic system, and product category is various, mainly comprises diaphragm type, piston type and spring etc.According to physics principle, be incompressible in the fluid reality, so can not the pressure store energy.Hydro pneumatic accumulator is to utilize the compressibility of gas to store fluid.Diaphragm accumulator is grouped into by the gentle body of liquid part, and barrier film is as the gas seal separator.Liquid part communicates with oil hydraulic circuit, thus pressure when raising gas compressed, fluid is inhaled into diaphragm accumulator.During pressure drop, gas expansion, thereby fluid ramming system loop.It is the utility model patent of ZL200820126919.5 that this series products such as State Intellectual Property Office are called " diaphragm accumulator " patent No. disclosed of on May 13rd, 2009, it comprises " upper shell; lower shell body and diaphragm of rubber; the upper shell top is provided with the inflation screw; the lower shell body bottom is provided with the liquid terminal screw; on described; lower shell body is for being welded to connect ... this kind welding type diaphragm accumulator not only has good performance, and be convenient to the integrated of fluid hydraulic equipment and modularization production, be particularly conducive to boundary dimension and strict industry such as the car industry of weight, broken through bottleneck in the past ".But the profile of this series products is comparatively slightly round, and height is comparatively approaching with diameter, as make large capacity accumulator product, its diameter of the housing also increases thereupon, certainly will cause the septum port size also to want corresponding increase, cause the seal distance of barrier film to increase, sealability and product application reliability reduce.For this reason, people expect to invent a kind of diaphragm accumulator product that is applicable to large capacity, high sealing performance, with satisfy navigation, metallurgy, military project, railway, the needs used of the different hydraulic environments such as ore deposit.
The model utility content
The technical problems to be solved in the utility model be overcome that existing similar accumulator product exists be unsuitable for large capacity diaphragm accumulator product manufacturing and the diaphragm seal distance is long, defective and the deficiency of easy leakage, provide a kind of good seal performance, accumulation of energy straight tube diaphragm accumulator capacious product to society.
The technological scheme that its technical problem that solves the utility model adopts is: the straight tube diaphragm accumulator comprises steel cylinders and is welded in respectively described cylindrical shell up and down inflatable interface, the hydraulic interface at reducing position, two ends; Described inflatable interface is provided with air valve, and described air valve appearance is provided with dust cap; Described cylinder lumen is provided with elastic diaphragm, and described elastic diaphragm is separated into the air chamber on top and the liquid chamber of bottom with described cylinder lumen; The opening end of described elastic diaphragm is fixed in the described cylinder inboard wall at reducing position, close described cylindrical shell upper end by metal clasp; Bottom centre at described elastic diaphragm is embedded with closing lid.Described elastic diaphragm opening end is provided with a pair of arc convex, and described metal clasp is embedded between two described arc convex.
The utility model straight tube diaphragm accumulator, because the accumulator of different capabilities is to realize that by the length that changes steel cylinders its diameter is constant, so the general supporting scope of elastic diaphragm is wide, component Applicable scope enlarges greatly, cost descends; Again owing to the opening end size of elastic diaphragm not along with accumulator volume increases, so seal distance remains unchanged, sealability is stable.This product has good seal performance, accumulation of energy capacity advantage large, applied widely, can satisfy navigation, metallurgy, military project, railway, the needs used of the different hydraulic environments such as ore deposit.
Description of drawings
Fig. 1 is the utility model product structure schematic representation.
Embodiment
As shown in Figure 1, the utility model straight tube diaphragm accumulator comprises the steel cylinders 1 at middle part and is welded in respectively inflatable interface 2, the hydraulic interface 11 at described cylindrical shell reducing position in two ends about in the of 1; Described inflatable interface 2 is provided with air valve 3, and described air valve 3 appearances are provided with dust cap 4; Described cylindrical shell 1 inner chamber is provided with elastic diaphragm 7, and described elastic diaphragm 7 is separated into the air chamber 5 on top and the liquid chamber 6 of bottom with described cylindrical shell 1 inner chamber; The opening end 12 of described elastic diaphragm 7 is fixed in described cylindrical shell 1 inwall at close reducing position, described cylindrical shell 1 upper end by metal clasp 9; For improving the sealability of described elastic diaphragm 7 and described cylindrical shell 1 inwall, described elastic diaphragm 7 opening ends 12 are provided with a pair of arc convex 8, and described metal clasp 9 is embedded between two described arc convex 8; In the bottom centre of described elastic diaphragm 7, be embedded with closing lid 10.
The below continues by reference to the accompanying drawings, the working principle of summary the utility model product.During manufacturing, according to the amount of capacity that the user orders goods, the steel cylinders 1 of intercepting corresponding length; After the reducing of two ends, then elastic diaphragm 7 component such as grade of packing into weld inflatable interface 2, hydraulic interface 11 is made one; Because the accumulator of different capabilities is to realize that by the length that changes steel cylinders 1 its diameter is constant, so elastic diaphragm 7 general supporting scopes are wide, component Applicable scope enlarges greatly, and cost descends; Again owing to opening end 12 sizes of elastic diaphragm 7 not along with accumulator volume increases, so seal distance remains unchanged, sealability is stable.During inflation, air chamber 5 pressure rises, elastic diaphragm 7 expand, until closing lid 10 is closed with hydraulic interface 11 bottom surfaces.During work, when pressure moment of hydraulic system rose, air chamber 5 diminished, elastic diaphragm 7 shrinks, and closing lid 10 is raised, thereby realized impact-absorbing, eliminate the function of pulsation, vibration damping noise reduction, stored energy and steady pressure.
