Abstract
The invention relates to a capsule stainless steel welded pressure vessel for energy accumulation, which comprises a cylinder, a gas orifice, a liquid orifice, an upper end socket and a lower end socket, wherein both ends of the cylinder are respectively welded with one end of the upper end socket and one end of the lower end socket, the other end of the upper end socket is welded with the gas orifice, and the other end of the lower end socket is welded with the liquid orifice; and the cylinder is made of seamless stainless steel tubes, and the upper end socket, the lower end socket, the gas orifice and the liquid orifice are all made of stainless steel materials. The structure and the method successfully solve the problems of low yield and constantly high price of the stainless steel energy accumulator in the industry, and save the materials and reduce the allocated cost, thereby creating a new way for the mass production of stainless steel energy accumulators.
Description
Technical field
The present invention relates to a seed capsules formula accumulation of energy stainless steel welding pressure container.
Background technique
Accumulator is as the important auxiliary in the hydraulic system, to guarantee hydraulic system normally move, improve its dynamic quality, keep working stability, prolong equipment operating life, do supplementary energy, reduce noise etc. and play important special use.Accumulator according to GB/T20663-2006 " capsule formula accumulation of energy pressurized container " design, production, main pressure restraining element material is Fine Steel Casting iron, Alloy Constructional Steel, and having satisfied hydraulic medium is the needs of the hydraulic system of hydraulic oil, emulsified liquid and similarity hydraulic medium thereof.When hydraulic medium is all kinds of industrial chemicals or food etc., accumulator is required that antiseptic property is arranged or from the health angle, the main pressure restraining element material of fitness for purpose accumulator is a stainless steel, and original Fine Steel Casting iron, alloy structure steel can not satisfy the real work needs.And have following problem to exist when mainly the pressure restraining element material is made the accumulator housing with reference to GB/T20663-2006 " capsule formula accumulation of energy pressurized container " with the stainless steel conduct:
1, all adopt when Fine Steel Casting iron, Alloy Constructional Steel material accumulator housing the method for tube section ends heating, rotary press modelling to make, as shown in Figure 3.
If adopt the method for tube section ends heating, rotary press modelling to make, the dome head inner and outer surface crackle after the moulding was difficult for eliminating when 2, stainless steel material was made the accumulator housing, and especially can't polish in end socket inside, and product percent of pass is very low, can't produce in enormous quantities.
Summary of the invention
Deficiency in view of prior art exists the invention provides a seed capsules formula accumulation of energy stainless steel welding pressure container,
The present invention for achieving the above object, the technological scheme of being taked is: a seed capsules formula accumulation of energy stainless steel welding pressure container, comprise cylindrical shell, gas port and fluid port, it is characterized in that: also comprise upper cover and lower seal head, described cylindrical shell two ends respectively with the welding of an end of upper cover and lower seal head, upper cover the other end welding gas mouth, lower seal head the other end welding fluid port; Cylindrical shell is a gapless stainless steel tube, and upper cover, lower seal head gas port, fluid port are stainless steel.
Characteristics of the present invention are: adopt said structure and method success solution in the industry stainless steel accumulator housing yield rate low, the situation that product price is high, saved material, reduced overhead cost, for large quantities of a large amount of production stainless steel accumulators have been started new approach.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the embodiment of the present invention structural representation.
Fig. 3 is the prior art constructions schematic representation.
Embodiment
As shown in Figure 1, capsule formula accumulation of energy stainless steel welding pressure container, comprise cylindrical shell, gas port and fluid port, it is characterized in that: also comprise upper cover 2 and lower seal head 3, described cylindrical shell 1 two ends respectively with the welding of an end of upper cover 2 and lower seal head 3, upper cover 2 the other end welding gas mouths 4, lower seal head 3 the other ends welding fluid port 5; Cylindrical shell 1 is a gapless stainless steel tube, and upper cover 2, lower seal head 3 gas port 4, fluid port 5 are stainless steel.Cylindrical shell 1 also can adopt the steel plate roll-forming, and the jointing of its cylindrical shell is by being welded into one.
Concrete way is: first step welding gas mouth, fluid port twice weld seam, the welding back requires the inside and outside weld bond of polishing according to drawing.Second step welding upper cover, lower seal head twice weld bond, the welding back requires the inside and outside weld bond of polishing according to drawing.So just avoided adopting the interior external crack that tube section ends heats, the method for rotary press modelling is made the dome head that causes.
Cylindrical shell 1 also can adopt roll of steel plate to make shape, and the jointing of its cylindrical shell is by being welded into one.The capsule formula accumulation of energy working principle of pressurized container, as shown in Figure 1, 2:
1, the accumulation of energy of capsule formula is with the basic structure of pressurized container: assembling has the component such as capsule of unidirectional gas charging valve in gas port, assemble bacterial type valve with support and folding function and the component such as fuel tap body that interconnect function is arranged in fluid port, fluid port is by the pipeline UNICOM of screw thread or flange and hydraulic system.
2, at first a certain amount of nitrogen is charged in the capsule, set up the pre-inflation pressure of accumulator after capsule expand into and is close to inner walls, be first state (next quantitative gas of Current Temperatures) this moment: volume V1, pressure P 1.Pressure medium rising when hydraulic tubing, when surpassing P1, the bacterial type valve of fluid port is opened, and liquid enters in the cylindrical shell, the volume-diminished of the gas that capsule is airtight forms second state (next quantitative gas of Current Temperatures): volume V2, pressure P 2 when pressure reaches the highest.When the pressure medium of hydraulic tubing reduced, liquid expelling tube gradually was external, and the volume of the gas that capsule is airtight increases, and formed the third state (next quantitative gas of Current Temperatures): volume V3, pressure P 3.
3, the relation of each parameter: V1＞V2, V1＞V3, V3＞V2; P1＜P2＜P2, P3＜P2, P1＜P3.
P1*V1=P2*V2=P3*V3 (not considering influence of temperature variation).
4, above process promptly utilizes equation of state of gas about the volume of a certain amount of gas, the correlation of pressure (not considering influence of temperature variation), when hydraulic tubing pressure raises, contraction of gas absorbs certain amount of fluid, when hydraulic tubing pressure reduces, discharge certain liquid to hydraulic tubing by fluid port.This process is to hydraulic equipment, can to guarantee hydraulic system normally move, improve its dynamic quality, keep working stability, prolong equipment operating life, do supplementary energy, reduce noise etc. and play important special use.
