Description

Изобретение относитс  к испытани м на герметичность полых изделий, заполненных газом.This invention relates to leak testing of hollow products filled with gas.

По основному авт. св. № 896441 известно устройство дл  испытани  изделий на герметичность, содержащее ванну с жидкостью, размещенный в ней колпак с отводной вертикальной трубкой , имеющей прозрачный участок и соединенной с вакуумньм насосом, фотооптический индикатор и импульсный акустический вибратор, установленный на наружной поверхности колпака 1.According to the main author. St. No. 896441, a device for testing leak tightness is known, comprising a bath with a liquid, a cap with an outlet vertical tube, having a transparent portion and connected to a vacuum pump, a photo-optical indicator and a pulsed acoustic vibrator mounted on the outer surface of the cap 1.

Недостатком известного устройства  вл етс  невысока  точность и достоверность испытаний, так как фотооптический индикатор надежно регистрирует пузырьки, диаметр которых не менее 10% диаметра вертикальной трубки, а размеры пузырьков от микронеплотности завис т от ее конфигурации и размера .A disadvantage of the known device is the low accuracy and reliability of the tests, since the photo-optical indicator reliably detects bubbles whose diameter is not less than 10% of the diameter of the vertical tube, and the size of the bubbles from micro-density depends on its configuration and size.

Цель изобретени  - повышение точности и достоверности испытаний.The purpose of the invention is to improve the accuracy and reliability of the tests.

Указанна  цель достигаетс  тем, что устройство дл  испытани  на Герметичность снабжено диафрагмой с калиброванным отверстием, установленной в отводной вертикальной трубке нижеThis goal is achieved by having a tightness testing device fitted with a diaphragm with a calibrated orifice installed in a vertical diverging tube below

На чертеже представлена схема устройства дл  испытани  изделий на герметичность.The drawing shows a diagram of a device for testing products for tightness.

Устройство содержит ванну 1 с жидкостью дл  размещени  издели  2, по15 груженный в нее колпак 3 с отводной вертикальной трубкой 4, имеющей прозрачный участок 5 и соединенной с вакуумным насосом б, и фотооптический индикатор 7.The device comprises a bath 1 with a liquid for placing the product 2, a cap 3 loaded into it with a vertical diverting tube 4 having a transparent section 5 and connected to the vacuum pump b, and a photo-optical indicator 7.

На наружной поверхности колпака 3 установлен импульсный акустический вибратор 3.On the outer surface of the cap 3 is installed pulsed acoustic vibrator 3.

В трубке 4 установлена диафрагма 9 с калиброванным отверстием, распо25 ложенна  ниже прозрачного участка 5, диаметр которогоIn tube 4, a diaphragm 9 is installed with a calibrated orifice located below the transparent section 5, the diameter of which
