Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
Shown in Fig. 1, Fig. 2, this diaphragm accumulator includes upper shell 3, lower house 4, back-up ring 5 and barrier film 6 etc..
Upper shell 3 and lower house 4 are connected by saw-tooth thread, it is ensured that bonding strength, have auto-lock function simultaneously.Upper shell 3 top center is provided with screwed hole, and charge valve 2 and upper shell 3 are threaded connection, and reaches sealing effectiveness by the sealing ring being arranged on charge valve.Charge valve 2 has protective cover 12, in transport, assembling, work process, charge valve 2 is effectively protected.It is provided with oil inlet and outlet bottom lower house 4.
Referring specifically to Fig. 4, lower house 4 is provided with a ring annular groove 41 on inwall, and the edge of groove is the protruding ring 42 with certain angle, and barrier film has projection the edge part 61 turned up, cannelure 41 and protruding ring 42 can carry out, with the edge part 61 of barrier film, the laminating that adapts, it is ensured that the sealing of barrier film 6.
Back-up ring 5 is installed between lower house 4 inwall and diaphragm edge portion 61, transmits the thrust from upper shell 3, prevent barrier film 6 to be blown under pressure simultaneously, it is ensured that the reliability that barrier film 6 is installed.
Being provided with spacing shoulder 9 on the inner ring of lower house 4, after upper shell is threadeded with lower house, lower end is pressed on spacing shoulder, it is prevented that conquassation diaphragm 6 in installation process.
Diaphragm material is rubber, is inlaid with limited block 7 bottom diaphragm 6, and limited block 7 diameter is more than the diameter of oil inlet and outlet bottom lower house 4, when barrier film 6 expands, it is prevented that portion septum 6 enters the barrier film 6 that oil inlet and outlet causes and damages, and plays the effect of protection.This limited block is embedded in barrier film, thus ensureing that barrier film is as a whole, it is ensured that sealing.
It is externally provided with support 1 at accumulator; the mode that support 1 is threaded connection and is welded to connect is formed by connecting; support is divided into several arm; the lower end of arm catches the outer ring, top of lower house respectively; the upper end of arm is commonly connected in a top disc; and higher than upper shell top, play the effect of protection charge valve.Support 1 is provided with screwed hole for installing when lifting bolt 8 is easily installed accumulator needed for lifting.The concrete installation site of lifting bolt 8 can be adjusted according to accumulator actual installation angle, thus avoiding the damage of outer surface in installing accumulator process.
Referring to Fig. 5, it is provided with uniform open slot 10 at upper shell 3 and lower house 4 outer surface, for screw thread being applied when installation and removal moment, easy disassembly.
The profile of the diaphragm accumulator shown in Fig. 1 and Fig. 2 is upper shell is hemispherical, and the cross section of lower house the first half is cylindrical, and the latter half is hemispherical.
Referring to Fig. 3, it is shown that the profile of diaphragm accumulator be upper shell be hemispherical, lower house is three sections of cylindrical structurals.This diaphragm accumulator does not set support, by being provided with protective cover on the charge valve at upper shell top, charge valve is protected.
During use, gases at high pressure are poured, by charge valve 2, the air chamber being made up of upper shell 3 and barrier film 6；Then the oil inlet and outlet bottom lower house 4 is connected hydraulic circuit, make hydraulic oil enter the liquid chambers being made up of lower house 4 and barrier film 6.When the pressure moment of hydraulic system rises, hydraulic oil enters liquid chambers, and barrier film 6 deforms under hydraulic fluid pressure effect and reduces, compressed gas chamber；When the pressure moment of hydraulic system declines, barrier film 6 expands under gas pressure, it is ensured that liquid chambers pressure remains unchanged, so that accumulator realizes absorbing the function of impact, vibration damping noise reduction, storage energy and steady pressure.
