Abstract
A method for preventing the negative pressure on the surface of vacuum solid container features that a rubber membrane is used to cover the top mouth of said container or a balloon is installed inside the container. The expansion of rubber membrane or balloon can balance the internal pressure with external one.
Description
The present invention is " a kind of solution of negative pressure on solid vacuum container surface ".
Vacuum storage is not mouldy insect-free, can be used for food fresh keeping, also can be used for guaranteeing the quality of a fur leather goods, has been widely used in flexible packaging.But, the surface of solid vacuum container, negative pressure is very big, and common plastic product or iron sheet goods can not bear this pressure, must be special, thereby the cost height, limited its range of use.
The objective of the invention is to, use simple means, solve the surperficial negative pressure of solid vacuum container, make common Plastic Drum or iron sheet barrel, do not thicken reinforcing, just can become vacuum vessel.
Method of the present invention is the whippy rubber diaphragm of overspread suitable for reading at solids container, forms airtight (as Fig. 1) or a balloon is installed in gas-tight container, and ball mouth and atmosphere lead to (as Fig. 3), opens bleeding point, dress valve down.Bleed outward from bleeding point with vacuum pump, when container inner pressure drop to 0.01 crust when (bar) rubber diaphragm or balloon begin to splash and rise, be close to the surface of container, reach internal and external pressure balance (as Fig. 2, Fig. 4), continue to vacuumize this moment, even reached the limit-0.1 crust (bar) of oil-sealed rotary pump, the negative pressure of vessel surface can not increase yet again, and common plastics or iron sheet container are the pressure that can tolerate 0.01 crust (bar).
Claims (2)
1, with rubber diaphragm or other elastic membrane, the characteristic that pressurized is splashed and risen reaches the balance of container external and internal pressure.
2, the method for splashing and rising with balloon reaches the balance of vacuum vessel external and internal pressure.
