Technical field
The utility model relates to the structure of ultrahigh pressure cylindrical shell.
Background technique
The ultrahigh pressure vessel kind equipment, such as large-scale, super-huge oil hydraulic cylinder, working pressure is very large, and the wall thickness of its barrel often requires tens centimetres, even requires guarantee equipment need of work more than 1 meter; Working pressure such as the hot isostatic pressing ultrahigh pressure vessel reaches 200MPa.Therefore the barrel manufacture difficulty of ultrahigh pressure vessel kind equipment is very large, and manufacture cost is also very large.Solution is to carry out prestressing force to strengthen processing before cylindrical shell uses at present, makes cylinder inboard wall produce plastic deformation, such as contracting cover, multilayer contracting cover technology; Another kind is the technology that adopts wrapping wire, strip winding, twines the subdivision technology such as reinforcement wire.But the method that adopts at present all exists manufacture difficulty large, and cost is very high, and can't thoroughly solve the problem of unbalanced stress, exists larger potential safety hazard in the use.
Summary of the invention
The purpose of this utility model provides a kind of superelevation pressure-volume wall construction, can greatly reduce manufacture difficulty and the manufacture cost of cylindrical shell.
The technical solution of the utility model is: a kind of superelevation pressure-volume wall construction, feature is to hold wall by N(N＞=2) cylinder set of individual different-diameter, or by N(N＞=2) appearance of individual different cambered surfaces lid suit, and hold wall construction by the multilayer that upper and lower cover or connecting plate fit sealing are connected.
All be filled with gas, the liquid or solid medium of conducting pressure between the adjacent appearance wall in the formed cavity, can be pressurized in advance a certain fixed pressure value rear enclosed in the cavity and use.
Formed whole cavitys or part cavity have pipeline to be connected to the pressure station between the adjacent appearance wall, and medium is gas, liquid, and the pressure large I in the cavity is regulated.
Upper cover can be welding, be spirally connected with holding wall connection fastening means with lower cover or connecting plate.
The utility model has overcome the technological deficiency that present general prestressing force enhancing technology is made the ultrahigh pressure vessel kind equipment, realized the distribution of appearance wall stress optimization, safety in utilization and the using effect of ultrahigh pressure vessel kind equipment have been strengthened, not only can satisfy original design, manufacturing technology requirement, and can greatly reduce manufacture difficulty and the manufacture cost of cylindrical shell.The utility model provides a kind of very practical and effective approach for making the equipment such as super-huge press machine, ultrahigh pressure vessel.

Fig. 2 is that the utility model appearance is covered structural representation.
Embodiment
As shown in Figure 1, oil hydraulic cylinder is comprised of upper cover 1, cylinder 2, lower cover 3, piston 4, and bolt 5 is fastenedly connected upper cover 1, cylinder 2, lower cover 3 to be integrated, and oil hydraulic cylinder is connected to hydraulic station by pipeline 6, cylinder chamber 7 is main active chamber, the back work cavity that cavity 8 forms for cylinder.The cylinder 2 of oil hydraulic cylinder is formed by cylinder a, cylinder b, cylinder c suit, and the diameter of cylinder a, cylinder b, cylinder c is all not identical.Cylinder a has formed cylinder chamber A, and cylinder a and cylinder b have formed cavity B, cylinder b and cylinder c has formed cavity C.The pressure of cylinder chamber A is P
A, the pressure of cavity B is P
B, the pressure of cavity C is P
CThe pressure P of cavity B, cavity C
B, P
CCan preset and respectively airtight, also can strengthen along with the pressure of cylinder chamber A and strengthen simultaneously.The pressure that the wall thickness of cylinder a, cylinder b, cylinder c can carry as required designs, and the wall thickness of each cylinder can be identical, also can be different.The maximum pressure of supposing cylinder chamber A is 90Mpa, and the maximum pressure of cavity B is 60Mpa, and the maximum pressure of cavity C is 30Mpa.During work, as the P of cylinder chamber A
ADuring for 90Mpa, because the P of cavity B
BBe 60Mpa, the pressure that acts on so cylinder barrel a is 90Mpa-60Mpa=30Mpa.Through the conduction of cavity B, and because the P of cavity C
CBe 30Mpa, the pressure that acts on so cylinder b is 60Mpa-30Mpa=30Mpa.Therefore, original technology only has 1 cylinder a to bear the pressure that cylinder chamber A produces, as the P of cylinder chamber A
ADuring for 90Mpa, cylinder a need to bear the pressure of 90Mpa.And adopt the utility model technology, and cylinder a only need bear the pressure of 30Mpa, and cylinder a is with respect to original technology, and its wall thickness can reduce greatly, and then the manufacture difficulty of oil hydraulic cylinder and manufacture cost reduce greatly.
Ultrahigh pressure vessel holds cover and 9 cover a by holding, holds and cover b, hold and cover the c suit and form as shown in Figure 2, hold cover a, hold cover b, appearance is covered and is fastenedly connected and is integrated by connecting plate 10, bolt 5, cavity volume 11 is main active chamber, cavity 8 is the back work cavity that appearance is covered formation.Hold and cover the end that a is positioned at cavity volume A, appearance covers a and appearance is covered formation cavity B between the b, and appearance covers b and appearance is covered c formation cavity C.Cavity volume A, cavity B, cavity C are connected to the pressure station by pipeline 6 respectively.The pressure of cavity volume A is P
A, the pressure of cavity B is P
B, the pressure of cavity C is P
CThe pressure P of cavity B, cavity C
B, P
CCan preset and respectively airtight, also can strengthen along with the pressure of cavity volume A and strengthen simultaneously.Hold and cover a, hold and cover b, hold the pressure that the wall thickness that cover c can carry as required and design, each holds the wall thickness that covers can be identical, also can difference, and material can be identical, also can difference.The maximum pressure of supposing cavity volume A is 90Mpa, and the maximum pressure of cavity B is 60Mpa, and the maximum pressure of cavity C is 30Mpa.During work, as the P of cavity volume A
ADuring for 90Mpa, because the P of cavity B
BBe 60Mpa, act on to hold the pressure cover a be 90Mpa-60Mpa=30Mpa.Through the conduction of cavity B, and because the P of cavity C
CBe 30Mpa, act on to hold the pressure cover b be 60Mpa-30Mpa=30Mpa.Therefore, original technology only has 1 appearance to cover the pressure that a bears cavity A generation, as the P of cavity A
ADuring for 90Mpa, hold and cover the pressure that a need to bear 90Mpa.And adopt the utility model technology, and hold and cover the pressure that a only need bear 30Mpa, hold and cover a with respect to original technology, its wall thickness can reduce greatly, and then manufacture difficulty and the manufacture cost of superelevation pressure-volume lid reduce greatly.
