Technical field
The utility model relates to a kind of under-water operation equipment, especially relates to a kind of built-in compensation hydraulic device that is used for subsea equipment.
Background technology
Include some conventional subsea equipments under water in the robot, such as joint box, storage battery box, propelling unit and hydraulic efficiency pressure system etc.For conserve space and the requirement of satisfying mounting arrangements, a lot of equipment all need to be directly exposed in the seawater, need bear the pressure of seawater, and can tolerate the corrosive property of seawater.In order to satisfy above condition, can take two kinds of measures usually, first kind is to adopt the pressure-resistance structure design, second kind is that device interior is full of hydraulic oil and connects the compensation hydraulic device under the feedwater.The employing pressure-resistance structure designs, and can increase the volume and the weight of subsea equipment, increases productive costs simultaneously; And at present the employed compensation hydraulic device of subsea equipment mostly is compensation hydraulic device independently, as the leather bag type hydraulic compensator, need be connected with oil-filled subsea equipment by pipeline, and the compensation hydraulic device of this form can't satisfy that subsea equipment is in light weight, volume is little, miniaturization, integrated development tendency.
The utility model content
The applicant is at above-mentioned problem, carry out research and improved, a kind of built-in compensation hydraulic device is provided, can be installed in the subsea equipment inside that is full of hydraulic oil, satisfy that subsea equipment is in light weight, volume is little, miniaturization, integrated requirement, reduce the manufacturing cost of subsea equipment simultaneously.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of built-in compensation hydraulic device, be installed on oil-filled subsea equipment inside, comprise front sleeve, back sleeve and rolling film, front sleeve is connected by flange with the back sleeve, front sleeve is provided with connecting device in-to-in through hole, and back sleeve is provided with the exterior through hole of connecting device; Rolling film is a cylindrical shape, is installed in front sleeve and the back sleeve, and the Gask-O-Seal of rolling film open end is fitted between front sleeve flange and the back sleeve flange, and rolling film is divided into inner chamber and exocoel with front sleeve and the inner space that the back sleeve constitutes; Piston is arranged in the exocoel and with rolling film captives joint, stage clip be arranged in the exocoel and be against piston and the back sleeve between.
Further:
Be provided with scale in the described exocoel, scale is provided with scale, and the described piston of an end captive joint of scale, the other end stretch out described back sleeve.
Technique effect of the present utility model is:
The disclosed a kind of built-in compensation hydraulic device of the utility model, can be installed in the subsea equipment inside that is full of hydraulic oil, simple in structure, installation and easy to maintenance, alleviated the weight of a whole set of subsea equipment, satisfy that subsea equipment is in light weight, volume is little, miniaturization, integrated requirement, reduce the manufacturing cost of subsea equipment simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the present invention includes front sleeve 1, back sleeve 7 and rolling film 5, front sleeve 1 is connected by flange with back sleeve 7, by bolt 6 front sleeve flange and back sleeve flange are fixed together, front sleeve 1 is provided with connecting device in-to-in through hole 101, and back sleeve 7 is provided with the exterior through hole 701 of connecting device.Rolling film 5 is a cylindrical shape, be installed in front sleeve 1 and the back sleeve 7, the Gask-O-Seal 501 of rolling film 5 open ends is fitted between front sleeve 1 flange and back sleeve 7 flanges, Gask-O-Seal 501 is inlaid in the groove of back sleeve 7 flanges, rolling film 5 is divided into inner chamber 102 and exocoel 702 with front sleeve 1 and the inner space that back sleeve 7 constitutes, rolling film 5 can play sealing function, and the inside and outside chamber of compensation hydraulic device is cut off, and seawater can't enter inner chamber 102.Piston 4 is arranged in the exocoel 702, and piston 4 is fixedly installed togather by cover plate 2 and the bolt 3 that is located in the inner chamber 102 with rolling film 5, and stage clip 8 is arranged in the exocoel 702 and is against piston 4 with afterwards between the sleeve 7.Be provided with scale 12 in the exocoel 702, scale 12 is provided with scale, can be used to indicate the compensation rate of compensator, and the left end of scale 12 is by screw thread captive joint piston 4, and the other end of scale 12 stretches out back sleeve 7.
In use, the compensation hydraulic device is installed in subsea equipment inside, is installed on the adapter plate 11 by bolt 9, and keeps sealing by O type circle 10, and adapter plate 11 is welded on subsea equipment shell 13 inboards, and scale 12 stretches out subsea equipment shell 13.The exocoel 702 of compensation hydraulic device is by hole and external environment connect on the subsea equipment shell 13, and inner chamber 102 is by through hole 101 connecting device inside, the mobile sea pressure on every side of deacclimatizing by piston 4 like this, and extraneous sea pressure is delivered to device interior.When the equipment topping up is pressed oil under the feedwater, after treating that hydraulic oil is full of the subsea equipment inner chamber, along with the increase of oil-filled amount, the application force that hydraulic oil can overcome stage clip 8 heads on piston 4 and moves right, and drive scale 12 and slowly stretch out, reach the scale that needs until scale 12 and stop to replenish hydraulic oil and get final product.
