Abstract
The present invention relates to auxiliary device for hydraulic system, is one kind of wound diaphragm type accumulator, and aims at providing accumulator with low cost and high production efficiency. The wound diaphragm type accumulator includes locking socket head cap screw, pressure container, diaphragm and valve seat, and the pressure container includes an upper casing and a lower casing. The present invention features the integral upper casing and the integral lower casing of several layers of wound belt. The upper casing and the lower casing are integral, firm, low in cost and high in production efficiency. The accumulator has no-pollution forming process and is suitable for hydraulic system in automobile, metallurgical, medicine, food product and chemical industry.
Description
Technical field
Type of the present invention relates to the auxiliary device field of hydraulic system, particularly, is provided in a side of and mainly plays a part stored energy, steady pressure, absorption in the hydraulic system and impact, eliminate pulsation, vibration damping.
Background technique
At present, the accumulator kind of one of hydraulic system middle auxiliary device is more.It also uses as eliminating pressure pulsation device except that the effect of playing storage and release pressure.Diaphragm accumulator is compared with piston accumulator, bladder accumulator, has the advantages that volume is little, in light weight, motor reaction is fast.Therefore, be widely used in hydraulic system auxiliary device field.Lower shell body is to adopt the welding procedure moulding on the pressurized container that welds diaphragm accumulator and select for use, because the barrier film that rubber material is made need adopt electron beam or laser bonding in inner walls during welding, the cost of welding equipment is higher.Select for use on the pressurized container of screw thread diaphragm accumulator lower shell body by the screw thread moulding that is tightened, connect because high pressure resistant outside is a ring shaped thread, belong to heavyweight, volume is bigger, carrying is owed just.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, strengthening unsaturated polyester composite with medium-alkali glass fibre is matrix, a kind of Wound diaphragm type accumulator is provided, substitute traditional prior art, make it can solve that prepared the present invention is light, safe in utilization, processing technology is easy, meet automobile industry and use high-level technical problem.The objective of the invention is to realize by the following technical solutions.
A kind of Wound diaphragm type accumulator, this accumulator comprise interior hexagonal lock screw, pressurized container, barrier film, valve seat.Described pressurized container divides goes up lower shell body, used material is respectively aluminum alloy, stainless steel, plastics, the last lower shell body that it is characterized in that pressurized container 2 is by twining belt 3 with the fibre reinforced composites multi-lay winding, make it be connected to integral body, connect with the alternative welding of the winding belt of multilayer, ring shaped thread and go up lower shell body.
The upper shell center portion of described pressurized container 2 is provided with inflation inlet, hexagonal lock screw 1 in inflation inlet connects.
The lower shell body center portion of described pressurized container 2 is provided with liquid entrance 6.
Be connected and fixed the two end part of barrier film 4 between the upper and lower casing of described pressurized container 2.
The center portion of described barrier film 4 connects valve seat 5.
This with the multi-lay winding band Wrapping formed diaphragm accumulator do not have soldering point, need not be threaded, lower shell body on lower shell body or the plastics on genus " no current fusion ", " not having cutting " connection metal, whole light, be connected firmly, cost is low, work efficiency is high, be a kind of accumulator of pollution-free moulding, have significant technological progress.
Description of drawings
Fig. 1 is a structural representation of the present invention, among the figure is that boundary is made as air chamber and liquid container with the barrier film.
Sequence number among the figure and title: 1, interior hexagonal lock screw, 2, pressurized container, 3, twine belt, 4, barrier film, 5, valve seat, 6, liquid entrance.
Embodiment
In conjunction with Fig. 1 embodiment of the present invention is described as follows: the present invention is applicable to that automobile chassis is connected in hydraulic system, the vibration damping auxiliary device when being vehicle-mounted; Also be applicable to metallurgical industry, medical industry, food industry, chemical industry equipment field, the present invention is connected the effect of playing stored energy, buffering, vibration damping, releasing energy with the pipeline of hydraulic system.The interior hexagonal lock screw 1 of the inflation inlet among Fig. 1 is to apply mechanically with the hexagonal screw rod of special use, be that the hexagonal screw rod is inserted in the interior hexagonal cavity of lock screw, unscrew this screw, its inflation inlet conducting, gas charges into to the pressurized container of the barrier film 4 of 5 bracketings of valve seat and screws this screw, and inflation inlet is promptly closed.Lower inner cavity is to communicate with the liquid that pressure is arranged by liquid entrance 6.The pressurized container pressure-bearing is respectively 10,20,31.5Mpa, also twines by different pressure-bearing grades so twine the level of belt 3.Described take-up strap is fibre reinforced composites, can tightly wrap the tight winding of mainly leaning on special device in pressurized container, adds a spot of binder again the top layer is fixed.When the inflation inlet gas introducing pressure that is connected is big, after expanding, barrier film 4 moves down.The fluid pressure that is connected as liquid entrance 6 is greater than the gas pressure of last inner chamber, and barrier film 4 expands and upwards floats, valve seat 5 also with on support.In a word, the hydraulic system pressure that the present invention connected is not both by the gas in the pressurized container and regulates, play the storage of auxiliary device and the function of release pressure, as be applied in play in the auto industry field in the automobile running steadily, the pressure of safety or system equipment regulates the effect of buffering, vibration damping.
