Abstract
The utility model relates to a 420MPa extra-high pressure energy accumulator with plane hard seals, which comprises an energy accumulator cylinder, choke plugs, energy accumulator end covers and the plane hard seals. Both ends of the energy accumulator cylinder are provided with the energy accumulator end covers with the same structure. Both the energy accumulator end covers are provided with the choke plugs with the same structure. The plane hard seals are arranged between the energy accumulator end covers at both the ends of the energy accumulator cylinder and both end faces of the energy accumulator cylinder. The energy accumulator end covers and the plane hard seals are fastened at both the ends of the energy accumulator cylinder by bolts to form sealing between metal surfaces and metal planes. The plane hard seals are precipitation-hardening stainless steels (products purchased in a city) which are subjected to heat treatment. The energy accumulator adopts a hard sealing mode of the precipitation-hardening stainless steels. Compared with the existing energy accumulator, the energy accumulator disclosed by the utility model has high bearing voltage and good sealing performance and is guaranteed to operate for 4,000 hours under the pressure of 420MPa without leakage.
Description
Technical field
The utility model relates to hydraulic accumulator, particularly relates to the 420MPa ultrahigh pressure plane that is applied to high-pressure water cutting machine and seals accumulator firmly.
Background technique
At present, high-pressure water cutting machine is in the water cutting process, be that (420MPa) carried out encapsulation process by accumulator when common instant water was pressurized to the ultrahigh pressure situation, the ultrahigh pressure accumulator, its sealing material adopts soft, hard sealings such as nylon, plastics, metal or stainless steel more, deficiency is, under the ultrahigh pressure operating mode, the working life of its sealing is limited, can not guarantee long-time sealing, country such as the U.S., Germany works out present state-of-the-art conical surface seal, but still produces the trace expansion, can't seal fully.
The model utility content
The technical problems to be solved in the utility model provides a kind of good seal performance, and the 420MPa ultrahigh pressure plane of long service life seals accumulator firmly.
The technological scheme that adopts is:
420MPa ultrahigh pressure plane seals accumulator firmly, comprises that accumulator cylindrical shell, chock plug, accumulator end cap and plane seal firmly.Described accumulator cylindrical shell two ends are provided with the identical accumulator end cap of structure, and two ends accumulator end cap all is equipped with the identical chock plug of structure.Be provided with the plane between the accumulator end cap at described accumulator cylindrical shell two ends and the accumulator cylindrical shell both ends of the surface and seal firmly, the hard sealing of accumulator end cap and plane is fastened on accumulator cylindrical shell two ends, constitute the sealing of metal covering and metal flat with bolt.
Above-mentioned plane is sealed into firmly through heat treated Precipitation-hardening Stainless Steel (commercial product).
Accumulator of the present utility model adopts the hard sealing means of Precipitation-hardening Stainless Steel, bears the pressure height than existing accumulator, good seal performance, guarantee accumulator under 420MPa pressure, operation in 4000 hours do not reveal.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
420MPa ultrahigh pressure plane seals accumulator firmly, comprises the hard sealing 4 in accumulator cylindrical shell 3, chock plug 1, accumulator end cap 5 and plane.Described accumulator cylindrical shell 3 two ends are provided with the identical accumulator end cap 5 of structure, and two ends accumulator end cap 5 all is equipped with the identical chock plug of structure 1.Be provided with hard sealing 4 between the accumulator end cap 5 at described accumulator cylindrical shell 3 two ends and accumulator cylindrical shell 3 both ends of the surface through heat treated Precipitation-hardening Stainless Steel plane, with bolt 2 the hard sealing 4 of accumulator end cap 5 and plane is fastened on accumulator cylindrical shell 3 two ends, constitutes ultrahigh pressure metal covering and metal flat and seal accumulator firmly.
