Description

 For testing materials for use, aspirator-type drives are used, in which an MapaoTia vessel is used as a tank and a sample is attached to a second flexible vessel connected to the first flexible ad- hede.

In these instruments, the air clears through the sample into the oigala tevivenia at the same speed as the pressure for the liquid that goes around the vessel with the sample, Postedenr®, goes up in Mfepe as the fluid level in the vessel U increases: -

The present invention seeks to create a uniform and push, through the air, so that it creates a constant amp; outflow of fluid in the vessel with a "h. The drawing shows a slit-through instrument. The vessel 1 for connection to sample 6 is made in the form of a coiled tube, through the bottom K) is passed to a certain second pipe 2 smaller than the predetermined distance.

(418) The liquid from vessel 5 is distilled into vessel 1 or by raising the vessel by air pressure around pipe 8 and displaces the gas from the cavity of vessel 1 at a constant rate during the experiment, since the flow of liquid 3–4 in vessel 1 is constant. and, therefore, the back pressure Hanoj) of the fluid entering CZ sbsud 5. is displaced permanently. Displaced from the cavity of the vessel 1, the gas with its pressure, which during the test is constantly in vessel 1, is pushed through 6 .

The coefficient of gas permeability of the sample is calculated by the formula:., Irf --.-,

where L is the volume of the passed saz, the rf is the thickness of the sample, F is the sample area, and p is the pressure difference and t is the time.

The proposed device is applicable in many areas of technology, for example, in the foundry business for determining the hygroscopic properties of molding materials, building materials and, finally, for explaining the durability of those materials that are exposed to gases. The device received the impression. in the All-Union, Institute of refractory and acid-resistant materials.

For delivery, the gas sample of the cylinder 1 is supplied with a transmissive pipe through its bottom. The division of the length of the tube 2 serves to feed the vessel with the speed of movement to the cylinder 1 at a Ctoaiioff.
