Description
Technical field
The utility model relates to other press such as being mainly used in alloy components die casting machine in the die casting field, ceramic brick press and steam-pressing brisk press, a kind of large flow bladder type hydropneumatic accumulator of large quantity of fluid abrupt release in producing fast.
Technical background
Along with modern development, enterprise has proposed the efficient work rate to press, the requirement of low energy consumption.Pumping plant uses pump-accumulator composite power, presses down fast, in the backhaul process, and pump-accumulator acts on simultaneously, and short time flow-rate ratio single-power system of system improves several times, reduces auxiliary time, and increasing work efficiency surpasses 30%.Pumping plant uses pump-accumulator composite power, and non-peak rate of flow state carries out Conversion of Energy by accumulator, the peak load that disappears, the peak rate of flow state, accumulator releases energy, oil pump is realized energy-conservation and synergy at the economical and efficient section operation, and the binary transformation of energy is brought 30% energy-saving effect.Present domestic Die Casting Enterprise uses accumulator to divide bladder and two kinds of piston types, bag type accumulator is quick on the draw, when but flow reaches 1800L/min, the liquid of a large amount of rapid flows can be given the huge impact force of bacterial type valve, bacterial type valve moment is closed, cause the interior a large amount of highly pressurised liquids of accumulator sap cavity to discharge not out, can't guarantee the normal operation of equipment; Piston accumulator can satisfy the traffic requirement above 1800L/min, but because the stiction of primary seal element is large between cylinder inboard wall and the piston, reaction velocity is slow, can't catch up with the fast operation cycle of equipment, so reduced working efficiency and the low energy consumption requirement of enterprise.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of production structure simple, easy to install and use, has satisfied a kind of large flow bladder type hydropneumatic accumulator of the high-speed large-flow releasing liquid in die casting field.
The utility model for achieving the above object, the technological scheme of taking is: a kind of large flow bladder type hydropneumatic accumulator, comprise the flange-type stream valve body that fixes by gland and locknut with the accumulator housing, the bacterial type valve, spring, piston, self-locking nut, the valve rod end of described bacterial type valve passes spring successively, flange-type stream valve body inner bore, piston is fixed on the flange-type stream valve body by self-locking nut, it is characterized in that: described flange-type stream valve body inner bore upper end is toroidal, be provided with a circle groove with the toroidal connecting part, the external diameter of groove is Φ 70mm, and the diameter that is provided with equidistant arrangement in groove is eight through holes of φ 16mm; The diameter of described bacterial type valve bonnet 2-1 is φ 88mm; The elastic force of described spring is 297N.
The beneficial effects of the utility model are: 1, reduce the diameter of bacterial type valve bonnet, become present φ 88mm by original φ 106mm, surface area is by 8824.7 original mm
2Become 6082.1 present mm
2, surface area reduces 31.1% like this, and when greatly reducing to flow valve body abrupt release liquid, fluid is to the impact force of bacterial type valve.2, reduce flange-type stream valve body upper end toroidal and coupled groove diameter and become φ 70; Reduce the area of microstome in the flange-type stream valve body recess, aperture becomes 8-φ 16 by original 6-φ 20, and orifice area is by 1885.0 original mm
2Become 1608.5mm
2, the microstome area reduces 14.7% like this, and the flow when reducing stream valve body abrupt release liquid reduces fluid to the impact force of bacterial type valve.3, the steel wire wire diameter of spring becomes φ 3.2mm by original φ 3.0mm, and maximum functional elastic force becomes 297N by original 168N, so greatly improves the anti-impact force performance that the bacterial type valve flows to large flow liquid.In a word, fuel tap body device anti-impact force performance obviously improves, in the using process during the large flow liquid of abrupt release, assurance bacterial type valve can not cut out, cause to discharge highly pressurised liquid, effectively raise the energy conversion efficiency of accumulator, enterprise is increased work efficiency, realize energy-conservation and successful synergy.
