Description
Technical field
The invention belongs to technical field of hydraulic pressure, more particularly, to a kind of metal diaphragm separated accumulator（Bellows or diaphragm type）For having pole high and low temperature, high air impermeability and high antiseptical operating mode.
Background technology
Accumulator is one of hydropneumatic system energy savings device, it is in due course the energy conversion in system is compression energy or potential energy stores, when system needs, compression energy or potential energy are changed into the energy such as hydraulic pressure or air pressure again and discharge, again mend feed system, when system instantaneous pressure increases, it can absorb the energy of this part it is ensured that whole system pressure is normal.Accumulator has two kinds of purposes：The flow that load needs when low-speed motion is less than hydraulic pump flow, and the unnecessary flow of hydraulic pump stores up into accumulator, and when loading demands flow is more than hydraulic pump flow, liquid is released from accumulator, to mend the deficiency of hydraulic pump flow；When shutting down but still need to maintain certain pressure, hydraulic pump can be stopped and the leakage by accumulator compensation system, to keep the pressure of system.Accumulator also can be used to absorb the hydraulic shock pressure producing in the pressure fluctuation of hydraulic pump or absorption system.Pressure in accumulator can be produced with compressed gas, weight or spring, and correspondingly accumulator is divided into gas type, Weight type and spring.The structure of the normal wind of existing accumulator has bellows, diaphragm type and piston accumulator, but the diaphragm element of these three accumulators all be unable to do without capsule material, it is all by the method isolation element of cooperation, air-liquid to be isolated, it is inevitably present certain seepage, in addition diaphragm element and the compatibility of medium also have certain limitation, temperature, cannot normal use beyond above-mentioned condition also substantially in -40/+120 DEG C of scope.
Content of the invention
The present invention provides a kind of metal diaphragm separated accumulator, to solve the problems, such as that in above-mentioned background technology, the welding type proposing and the screw-type suitability be not strong.
Technical problem solved by the invention employs the following technical solutions to realize：The present invention provides a kind of metal diaphragm separated accumulator, is used for high and low temperature, air impermeability and high antiseptical operating mode it is characterised in that：Including housing, end cap, three way cock, piston, metal diaphragm and fuel tap body, described housing, end cap form an airtight container, described housing tip is connected with a three way cock, it is provided with described piston and metal diaphragm in described housing, corrugated described metal diaphragm upper end is connected with described piston, lower end and described end cap assembling, are provided with fuel tap body in the middle part of described end cap.
Described housing tip is provided with a screwed hole, and screwed hole is used for connecting described three way cock.
Described three way cock can connect charge valve and sensor or pressure gauge.
Described housing, end cap are connected by way of flange, screw thread or welding.
Described piston side is provided with wear ring.
Being made up of high-performance metal materials of described metal diaphragm.
The material of described metal diaphragm is rustless steel and titanium alloy.
Described metal diaphragm welded top has some weld bolts, and bottom welding has outer threaded adapter.
Metal diaphragm separated accumulator is bellows or diaphragm type.
End cap, metal diaphragm and piston form a complete isolation element, and the isolation element of metal is made with the material being adapted with working media and operating condition, and such as rustless steel and titanium alloy etc. is characterized in thering is elasticity and toughness well.Metal isolation element is an element carrying adapter, has good air valve.The adapter of metal isolation element and end cap are connected and ensure its sealing.The other end of separator is connected with the guiding of separator, its guiding be to ensure that isolation element move up and down during keep it from by stuck or reverse situations such as and lead to isolation element to be damaged.Guiding has certain gap it is ensured that fairlead moves up and down freely with the inner surface of housing.Accumulator is divided into air cavity and sap cavity by isolation element.Metal diaphragm is to be welded into using high-energy such as laser.
Beneficial effects of the present invention are：
1. by the sealing of metal separator so that accumulator has good air-tightness, helium leak test can reach very high rank to the technical program, can be required very high high-end system application.The diaphragm element long service life of accumulator.
2., due to adopting all-metal, the use temperature of accumulator can greatly be protected exhibition, such as be adopted rustless steel, lowest temperature can reach -196 DEG C, maximum temperature can reach 375 DEG C.Its breathability, can reach 10 with helium leak test-7SCC/sec (cubic centimetre per second).The selection of the different materials of isolation element, so that accumulator has the good compatibility and erosion resistance to various liquid.
3. housing and metal isolation element adopt rustless steel, and antiseptic property is good, and the difference according to medium can select corresponding material, with most effectively ensure and medium the compatibility, can be used in the system of high corrosion.
4. metal isolation element is connected with guide, effectively can keep separator it is ensured that the life-span of product.
5., due to all-metal, elastomeric material can be avoided and leads to the restriction to case weld using the method for welding.
6. isolation element can be made frivolous, that is, alleviate weight by the pressure balance of metal diaphragm elements on either side, be conducive to improving the ability of resisting fatigue again.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further：
In figure：1- sensor, 2- three way cock, 3- charge valve, 4- housing, 5- piston, 6- wear ring, 7- welding screw, 8- nut, 9- metal diaphragm, 10-O shape circle, 11- ring washer, 12- end cap, 13- sealing ring, 14- locknut, 15- fuel tap body,
