Abstract
The invention provides a fluid pressure cavity of a simulated cavity film structure. The pressure cavity is designed in accordance with a cavity film structure, a metal shell is responsible for bearing pressure of high-pressure fluid in the pressure cavity, and the problem of slow leaking of fluid under the high-pressure condition is solved by an inner-layer cavity film structure. The pressure cavity has the advantages of long service life, test pressure stability and test result reliability.
Description
Technical field
The present invention relates to the long term seal of pressure chamber inner fluid, a kind of airtight hydrodynamic pressure chamber of long-term (3-5) anti-leakage is provided.
Background technique
Pressure chamber is made of two-part usually, and a part is the main body of cavity structure, and another part forms airtight cavity body structure by smooth junction plane and main body.The main body of junction plane both sides and the difference in size of mating part are more little, and the sealability of pressure chamber is more good.For further enhanced leaktightness effect, be provided with 1-2 road seal ring on the junction plane of pressure chamber usually.
The seepage of seal-off pressure chamber inner fluid is the key factor of restriction hydrodynamic pressure cavity pressure long-term stability.As the oil pressure chamber of anchor pole/anchor cable working resistance testing instrument, flat jack, material creep performance test apparatus, all there is the leakage problems of liquid under the hyperbaric environment in common fluid pressure chamber.Slow and the lasting seepage of pressure chamber inner fluid not only directly causes the instability of pressure to change, and also might cause the inefficacy of testing apparatus or instrument.For example the slow seepage of the interior oil pressure of anchor pole/anchor cable working resistance testing instrument can cause the continuous decline of anchor pole/anchor cable working resistance, directly influence the degree of accuracy of test data, and after the total amount of seepage liquid reached the internal stock of pressure chamber, whole test instrument completely lost power of test.
Unresolved the problems referred to above, a lot of instruments change the liquid in the pressure chamber into mobile relatively poor butter solid.This behave can only delay the seepage speed of material in the pressure chamber, and has a strong impact on the testing precision of pressure, but can not be from not catching up with the present situation of inner fluid continuous seepage in seal-off pressure chamber under the high pressure conditions.
In fact, the main leakage passage of pressure chamber inner fluid is the junction plane of pressure chamber.Though the obstruction of 1 road even multiple-sealed circle is arranged, under hyperbaric environment, fluid still can infiltrate from the slit slowly, has a strong impact on working life and the test effect of pressure chamber.
The leakage problems that solves fluid under the condition of high voltage can be packaged in fluid in the thin flexible rubber bag of good springiness, parietal layer, and rubber bag is placed pressure chamber, fundamentally blocks the passage of fluid leaks.
Summary of the invention
The invention provides a kind of hydrodynamic pressure chamber of powerful leakage proof, customer service the defective that existing pressure chamber leakage problems can't solve, test accuracy can't guarantee, working life is short.
This patent is applied to the antiseepage principle of chamber membrane structure among the antiseepage in mechanical pressure chamber, and concrete technological scheme is:
Utilize the rubber bag of pressure chamber inside to prevent seepage, and the pressure of rubber bag inner fluid is applied on the mechanical cavity by extremely thin rete.Similar is the Tire ﹠ Tube principle of bicycle with it: the inner tube of a tyre is responsible for preventing that the gas in it from overflowing, and cover tire is responsible for bearing the high pressure of gas.
Membrane structure hydrodynamic pressure chamber, a kind of imitative chamber
The built-in antiseepage rubber bag of the pressure chamber that this invention is related can be made according to shape and the size of pressure chamber.
Description of drawings
Be example with common flat jack built-in chamber film (rubber bag), the structure in imitative membrane structure hydrodynamic pressure chamber, chamber is described.
Fig. 1 is the elevation cross-sectional view of imitative chamber membrane structure flat jack, and Fig. 2 is plan view, and Fig. 3 is the three-dimensional section view of imitative chamber membrane structure flat jack.
Embodiment
Below in conjunction with accompanying drawing patent of the present invention is further specified:
Set outward appearance and the size of built-in chamber film according to the physical dimension of flat jack inner chamber.Chamber film outer wall dimension and flat jack inner chamber size suitable, the thickness of chamber rete is no more than 1mm.Chamber film outer wall is preset one section thin walled tube layer structure, guarantees that pressure gauge and flat jack inner chamber joint are non-leakage.
Claims (3)
1. imitate membrane structure hydrodynamic pressure chamber, chamber, essential characteristic is that it utilizes the metal shell pressure-bearing, utilizes the film antiseepage of built-in chamber.
2. chamber membrane structure hydrodynamic pressure chamber according to claim 1 is characterized in that the powerful anti-seepage effect of pressure chamber.
3. as chamber membrane structure pressure chamber as described in the claim 1,2, the main leakage passage of high-pressure liquid that it is characterized in that its shutoff.
