Description
Известны способы испытани герметичности полости, основанные на иснользовании манометра, фиксирующего давление в момент прорыва газов из полости, но эти способы не были разработаны, в частности , дл проверки плотности прилегани к лицу шлема противогаза.Methods are known for testing the tightness of a cavity based on the use of a pressure gauge fixing the pressure at the moment of gas breakthrough from the cavity, but these methods have not been developed, in particular, to check the tightness of the face of the gas mask helmet.
Особенность описываемого способа состоит в том, что герметичность прилегани шлема к лицу определ етс по падению избыточного давлени , создаваемого выдыхаемым воздухом под шлел1ом по линии герметизации .и замер емого при помощи,манометра.The peculiarity of the described method is that the tightness of the helmet to the face is determined by the drop in overpressure created by the exhaled air under the helmet along the sealing line and measured with a pressure gauge.
На чертеже изображена схема прибора, по сн юша прием осуш.ествлени описываемого способа.The drawing shows a diagram of the device, as shown by the method of drying the described method.
Прибор состоит из мембранного манометра / со шкалой от О до 400 мм вод. ст., клапанной коробки 2 с ниппельным гнездом, позвол юшим присоединить лицевую часть шлема, клапана 5вдоха от фильтрующего противогаза, соединительной трубки 4 и лицевой части 5.The device consists of a membrane manometer / with a scale from 0 to 400 mm of water. Art., valve box 2 with a nipple socket, allowed to attach the front part of the helmet, the valve 5in breath from the filtering gas mask, connecting tube 4 and the front part 5.
Пор док испытани герметичности лицевых частей ШВС (шлем водно-сухопутный) состоит в следующем.The procedure for testing the tightness of the front parts of the air-supply system (water-land helmet) is as follows.
Человек, одевший лицевую часть, делает глубокий вдох через клапан вдоха, и затем постепенно выдыхает весь воздух в прибор.The person wearing the front part takes a deep breath through the intake valve, and then gradually exhales all the air into the device.
При выдохе создаетс давление нод лицевой частью. Когда это давление достигает такой величины, при которой воздух начинает выходить из-под лицевой части по линии герметизации, стрелка мембранного манометра останавливаетс .During exhalation, pressure is created by the nodes of the face. When this pressure reaches such a value that the air begins to flow out from under the front of the sealing line, the diaphragm gauge needle stops.
Лицева часть считаетс герметичной, когда выход воздуха по линци .герметизации наступает при давлении под лицевой частью не ниже 250 мм вод. ст.The front part is considered as airtight when the air outlet along the sealing line occurs at a pressure under the front part of not less than 250 mm of water.

Предмет изобретени Subject invention
Способ испытани герметичности прилегани шлема противогаза к лицу, отличаю щи и с тем, что герметичность прилеган-и шлема к лицу определ етс с помощью манометра о падению избыточного давлени , создаваемого выдыхаемым воздухом под щлемом по линии герметизации.The method of testing the tightness of the fit of a gas mask helmet to the face is also distinguished by the fact that the tightness of the fit helmet to the face is determined with a pressure gauge on the drop in overpressure created by exhaled air under the clamp along the sealing line.
