Abstract
The utility model discloses a pressure compensating device for a deep sea hydraulic system, which comprises a plurality of tension springs, two flanges, connecting heads and rubber leather bags. The tension springs are connected between the two flanges; the rubber leather bags are positioned between the flanges and at the inner sides of the tension springs, and the upper ends and the lower ends of the rubber leather bags are vulcanized and are connected with the flanges into a whole body; and the connecting heads are communicated with the flanges. The pressure compensating device has the beneficial effects that as the rubber leather bags are arranged between the upper and the lower flange and are connected with the flanges into a whole body, hydraulic oil is filled in the rubber leather bags through the connecting heads communicated with the flanges; the flanges are connected with each other through the tension springs, so that the acting forces of the tension springs are always applied onto the two ends of each rubber leather bag to compress the hydraulic oil and satisfy the compensation dosage of the hydraulic system; and as the pressure of the hydraulic oil in the rubber leather bags is adjusted through extending and contracting the tension springs uniformly distributed on the peripheries of the flanges, the pressure compensating device is simple in structure, is good in stability and low in cost.
Description
Technical field
The utility model relates to a kind of deep-sea hydraulic system pressure compensation device.
Background technique
Instrument and equipment in use at the deep-sea; Do not expose in seawater there being the high-pressure chamber protection; The influence of abyssal environment high pressure is very big to its influence, and generally, the hydraulic system of deep-sea instrument and equipment need adopt pressure compensator; With balance abyssal environment pressure, and then protect it not by the hyperbaric environment crushing.
Application number is 2011200447765 Chinese patent; Showed a kind of deep sea pressure compensator, formed that effect has a cam on FlexbleJoint top by horizontal force mechanism, augering screw, vertical application mechanism, cam, FlexbleJoint, upper plate and housing; The both sides of cam act on two horizontal force mechanisms and vertical application mechanism respectively with top; Under the effect of augering screw, cam can move up and down, and then the drive FlexbleJoint moves up and down; Realize hydraulic oil row, suction in the FlexbleJoint, accomplish the pressure compensation of hydraulic system.This deep sea pressure compensator superstructure is complicated, and overall volume is excessive, and stability is bad, and expense is high.
The model utility content
The order of the utility model is to provide a kind of good stability, volume is little, cost is low deep-sea hydraulic system pressure compensation device.
The deep-sea hydraulic system pressure compensation device that the utility model provides; It comprises extension spring, flange, connecting head and rubbery human body; The quantity of flange is two, connects a plurality of extension springs between the flange, rubbery human body between flange, the inboard of extension spring; It up and down all vulcanizes with flange and fuses in two ends, and connecting head is communicated with flange.
Said flange is the plectane structure, outer circumference circumferentially be uniformly distributed with a ring through hole, a tapped through hole with said connecting head coupling is offered in the centre of plectane.
Said extension spring is straight hook spring, and the straight hook in its two ends passes and hook the corresponding circumferential through hole of flange respectively.
The utility model places rubbery human body between two flanges; And fuse with flange; Make through the connecting head that is communicated with flange and to be full of hydraulic oil in the rubber capsule; Connect through extension spring between the flange, make the two ends of rubbery human body have the active force of extension spring to compress hydraulic oil all the time, satisfy the compensation rate of hydraulic system.The utility model stretches through the extension spring that is distributed in the flange circumference and regulates the pressure of hydraulic oil in the rubbery human body, and simple in structure, good stability, cost are low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the schematic top plan view of Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2, the deep-sea hydraulic system pressure compensation device that the utility model provides mainly is made up of extension spring 1, flange 2, connecting head 3, rubbery human body 4.Flange 2 is the plectane structure, outer circumference circumferentially be uniformly distributed with a ring through hole, a tapped through hole with connecting head 3 couplings is offered in the centre of plectane; Connect a plurality of extension springs 1 between the flange 2, extension spring 1 is straight hook spring, and the straight hook in its two ends passes and hook the circumferential through-hole of flange 2 correspondences respectively; Rubbery human body 4 between flange 2, the inboard of extension spring 1, the flange 2 that its upper and lower end vulcanizes respectively with two ends fuses; Connecting head 3 is straight-through inner cone hose coupling, and the hydraulic oil pipe that its underpart and flange 2 screw threads are affixed, top is linked in sequence unidirectional stop valve and hydraulic system makes rubbery human body 4 the insides be full of hydraulic oil.
Rubbery human body 4 is under the effect of extension spring 1; Hydraulic oil pressurizeds in the rubbery human body 4 and keep certain pressure, this pressure is the compensatory pressure of hydraulic system, simultaneously; Rubbery human body 4 is under the effect of extension spring 1; Can upper and lowerly stretch: equipment is in transferring process, and hydraulic system pressurized and compressing, rubbery human body 4 are under extension spring 1 effect and compress; In the equipment callback course, hydraulic system pressure reduces and expands, and extension spring 1 is upheld, and rubbery human body 4 is followed bulging.
During work, according to the size of the selected rubbery human body 4 of the needed compensation rate of hydraulic system, after the equipment entry; The hydraulic system pressurized of equipment and shrinking; Rubbery human body 4 is followed contraction under the effect of extension spring 1, when seabed operation, because the effect of extension spring 1; The two ends of rubbery human body 4 have active force compression hydraulic oil all the time, satisfy the compensation rate of hydraulic system.
