Description

The invention relates to the field of machine building, in particular to the technique of leak testing. A device for monitoring the testing process is known | containing the sample-with video, the change of which is judged on the degree of detection of defects in products ij. However, additional experiments on the calibration of the sample are required, which allow to objectively judge the course of {the testing. The technical solution closest to the invention is a device for monitoring the tightness of gdravpicheskih testing containers with a glued filtering layer containing a sample - a witness with a calibrated leak 23. By regulating the loading of the element, the samples with applied defects change the deposition rate of a vapor-suspended particle. The disadvantage of this device is the impossibility of regulating the leakage through the defect of the specimen-witness within wide limits. Defects are not permanent under load, which reduces the objectivity of the control. The aim of the invention is to increase the objectivity of the control. This is achieved by the fact that the sample witness is made in the form of a vessel floating in a container, a set of ballast weights installed on its bottom, a chamber with a drain tube and a regulating valve installed inside the vessel with a calibrated leak, and the device is equipped with a filter layer that is glued outside on calibrated leak. In drawing 15), a schematic diagram of the proposed device is supplied. The device comprises a vessel 1 floating in the test container 2, a set of ballast weights 3, a chamber 4, a drain tube 5, a control valve 6, a calibrated flow 7, a filter layer 8, glued outside the vessel 1 to a calibrated leak.

The device works as follows.

Water with suspended particles was poured into the test container 2 with the filtering unit 9 glued. The tank was installed in the water by adjusting the depth of the vessel with ballast weights 3.

In the test tube) flowing through the flow 7, into the vessel, WATER INSTALLATION On is poured in using the adjusting valve 6.

After the test, the water from the tank was 5 ial, and a filtering layer was applied. Q and compare the intensity nsrreH on Him with the spots on the filtering layer 8.

A positive effect is achieved by comparing the spots on the filter beds in the SHK-vessel, allowing for & Handle and determine the magnitude of defects with high accuracy. Formula and, 3 obrete n and

The device for testing is sealed during hydraulic tests of containers with a glued filtering Layer, contains a sample witness with a calibrated leak, characterized in that, in order to increase the objectivity of the control, the sample - witness is filled with a set of ballast weights installed in the vessel. its bottom, chambers with a drain tube and a regulating valve installed on the wall with a calibrated leak inside the vessel, and the device is equipped with a filter layer glued on the outside of the vessel. flow.
