SU31664A1 - Apparatus for hydraulic testing of fabrics - Google Patents

Description

Rubberized fabrics are usually tested with fluids with varying head pressure and without bringing the object and circumstances tested to the initial conditions of the experiment. Therefore, inaccurate test results are obtained.

The proposed device is intended to eliminate the indicated defects, introduce an element of time in the test and. Give accurate digital values.

In and ate x. It is possible to completely remove air from the system of the device, the chamber serving to fix the test sample is made rotatable on an axis and equipped with a cranked exhaust pipe with two openings, one of which serves to receive air remaining in the system when it is set to its normal working position, and the other is to remove air from the air system from the system at the time it is filled with liquid.

The drawing shows a vertical section of the device ..

The camera 4 rotating the horizon, along the axis 5, serves to fix a sample on it / made from rubberized fabric, by means of the frame 2 and eccentrics J.

The right part of the chamber has the shape of a cone, which facilitates the removal of air from it and for this purpose, equipped with a cranked exhaust pipe zero (0) on it division, is (338),; . :

from the axis 5 at the same distance K, at which the fabric is from the latter. The tube 6 is equipped with two holes 8 and S, of which the end 8 serves to receive air remaining in the system when the device is installed in the normal position, and the hole 5 closed by the stop screw 9 is for removing air from the system at the moments of filling it with liquid. ,

Chamber 4 by means of a flexible hose / (connects to a pressure reservoir // having filling and drain valves 72 and / 5 and a tube J4 open at both ends. The vessel // and tube M are graduated. The design of the vessel 7 / ensures constant pressure //, the hydrostatic value of which is determined by the height of the position of the vessel 77.

Before testing a sample of a vessel 77, by means of a closed flexible body 75, thrown over blocks 75 and 76, it is balanced by a weight 77 and lowered by means of a 7P hand bar until 7 times until the level of the head gauge of the vessel, the scale zero and sample mt level will not be and be in one line, then the apparatus is charged with liquid through valve 72, the latter is closed and the test is performed under pressure H, noting the time of the test. At the end of the test, volumes and heights are brought to zero level.
