Description
Technical field
The present invention relates to accumulator technical field, particularly explosion-proof type piston power accumulator.
Background technique
Existing accumulator, when using hydraulic system to have an idle operation, incompressible high pressure liquid force feed is injected in accumulator and is stored, so that different time and demand, the system that is fed to uses, and can repeat to use.So, system effective utilization can be made full use of, and significantly reduce whole hydraulic system and consume the energy.To in recent years, do one's utmost all over the world pursue alternative energy source and advocate carbon reduction, accumulator not still prospective sharp weapon have practicability concurrently.
The more common problem of existing piston power accumulator is generally the internal leakage of piston sealing structure, due to the inertia of piston and the friction of Sealing, make sealing configuration impaired, cause sealing configuration ineffective, in addition due to its sealing, little, very unstable time large during air pressure inside accumulator, if the air pressure in accumulator increases, when energy is not externally provided in time, just likely produce blast, cause great loss, there is serious potential safety hazard.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, good seal performance, the explosion-proof type accumulator of use safety.
Realize technological scheme of the present invention as follows:
Explosion-proof type piston power accumulator, comprise tank body, the upper end cap of tank body upper end and the lower end cap of lower end are set, and the piston be arranged in inner tank wall, piston is used for tank body to be divided into two independently air cavity and oil pockets, upper end cap is provided with suction port, lower end cap is provided with filler opening, the side that described piston is connected with inner tank wall is provided with sealing layer, ball layer is provided with between sealing layer and piston, the ball of densely covered multiple mutual extruding in ball layer, be positioned at oil pocket and be provided with cushion plate, cushion plate is connected by spring with piston, the diameter of cushion plate is consistent with the diameter of piston.
The described end face being positioned at the piston of suction port side is provided with groove, and advantage is the volume that can increase gas compartment, thus increases gas flow, ensures enough pressure and makes piston movement.
Described air cavity and suction port are positioned at the same side, and oil pocket and filler opening are positioned at the same side, and the gas poured in air cavity is nitrogen.
Described ball layer is set to rubber material, and ball is lived by rubber coated, and described sealing layer adopts caulking gum, and advantage is that the deformability of rubber is strong, can adapt to the interaction force of ball.
The side that described cushion plate contacts with inner tank wall is provided with the sealing layer identical with piston and ball layer, and advantage can make to form airtight cavity between cushion plate and piston, prevents fluid from entering this cavity, thus prevent cushion plate and the ineffective power of spring.
Have employed above-mentioned scheme, in the movement process of piston, ball layer can be constantly stressed thus mutually extrude, the power of extruding reaches on rubber layer, such rubber layer can be close to inner tank wall or guiding rib, thus forming good sealing configuration, the setting of ball layer simultaneously also can make piston move smoothly; In addition, if after rubber layer receives wearing and tearing, ball layer can compensate, such rubber layer all the time with inner tank wall or guiding rib close contact, sealability can not reduce, and substantially prolongs its working life; When the pressure in air cavity or oil pocket is excessive, now, cushion plate will be extruded, spring contraction, by cushion plate and spring be used for alleviate the pressure in air cavity or oil pocket, thus avoid accumulation of energy gas explosion to explode, greatly strengthen the Safety performance of use.
