Description
Technical field
The utility model belongs to technical field of hydraulic pressure, particularly relates to a kind of metal diaphragm separated accumulator (bellows or diaphragm type) for having pole high and low temperature, high air impermeability and high corrosion-resistant operating mode.
Background technique
Accumulator is a kind of energy savings device in hydropneumatic system, it is in due course the energy conversion in system is that compression energy or potential energy store, when system needs, again compression energy or potential energy changed into the energy such as hydraulic pressure or air pressure and discharge, again supply system is mended, when system instantaneous pressure increases, it can absorb this part energy, ensures that whole system pressure is normal.Accumulator has two kinds of purposes: the flow that load needs when low-speed motion is less than oil hydraulic pump flow, and the unnecessary flow of oil hydraulic pump stores up into accumulator, and when loading demands flow is greater than oil hydraulic pump flow, liquid is released from accumulator, with the deficiency of fluid infusion press pump flow; When shutdown but still when need maintain certain pressure, can stop solution press pump and by the leakage of accumulator bucking-out system, with the pressure of keeping system.Accumulator also can be used to the hydraulic shock pressure produced in the pressure pulsation of absorption liquid press pump or absorption system.Pressure in accumulator can produce with pressurized gas, weight or spring, and correspondingly accumulator is divided into gas type, heavy hammer 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 kinds of accumulators all be unable to do without capsule material, all by the method isolated component of cooperation, gas, liquid are isolated, inevitably there is certain seepage, the compatibility of diaphragm element and medium also has certain limitation in addition, temperature is also roughly the scope of-40/+120 DEG C, and exceeding above-mentioned condition just can not normal use.
Model utility content
The utility model provides a kind of metal diaphragm separated accumulator, to solve the welding type that proposes in above-mentioned background technology and the not strong problem of thread type applicability.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of metal diaphragm separated accumulator, for having height, low temperature, air impermeability and high corrosion-resistant operating mode, it is characterized in that: comprise housing, end cap, tee union, piston, metal diaphragm and fuel tap body, described housing, end cap forms an airtight container, described housing tip is connected with a tee union, described piston and metal diaphragm is provided with in described housing, corrugated described metal diaphragm upper end is connected with described piston, lower end and described end cap assemble, fuel tap body is provided with in the middle part of described end cap.
Described housing tip is provided with a tapped hole, and tapped hole is for connecting described tee union.
Described tee union can connect gas charging valve and sensor or pressure gauge.
Described housing, end cap are connected by the mode 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 stainless 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 isolated component, and the isolated component of metal makes with the material adapted with working medium and operational condition, as stainless steel and titanium alloy etc., is characterized in having good elasticity and toughness.Metal isolated component be one with adapter element, there is good air valve.The adapter of metal isolated component and end cap are connected and ensure its sealing.The other end of separator is connected with the guiding of separator, and its guiding ensures that isolated component keeps it be not subject to the situations such as stuck or torsion and cause isolated component to damage in the process of moving up and down.Guiding has certain gap with the internal surface of housing, ensures that guide sleeve moves up and down freely.Accumulator is divided into air cavity and sap cavity by isolated component.Metal diaphragm adopts the high-energy such as laser to be welded into.
The beneficial effects of the utility model are:
1. the technical program is by the sealing of metal separator, and make accumulator have good tightness, helium leak test can reach very high rank, can do the application of exigent high-end system.The diaphragm element long service life of accumulator.
2. owing to adopting full-metallic, the serviceability temperature of accumulator greatly can protect exhibition, and as adopted stainless steel, lowest temperature can reach-196 DEG C, and maximum temperature can reach 375 DEG C.Its gas permeability, can reach 10 with helium leak test
-7sCC/sec (cubic centimetre per second).Selecting of the different materials of isolated component, can make accumulator have good compatibility and erosion resistance to various liquid.
3. housing and metal isolated component adopt stainless steel, and antiseptic property is good, and the difference according to medium can select corresponding material, to ensure most effectively and the compatibility of medium, can be used in the system of high corrosion.
4. metal isolated component is connected with guiding element, effectively can keep separator, ensures the life-span of product.
5. due to all-metal, the method for welding can be adopted, avoid the restriction that rubber material causes case weld.
6. the pressure balance of metal diaphragm elements on either side, can do frivolous by isolated component, namely alleviate weight, is conducive to again the ability improving antifatigue.
