Изобретение относитс к устройствам дл создани известной концентрации пара в газе и может быть использовано, например, дл калибровки чувствительных элементов при коррозионных испытани х.The invention relates to devices for creating a known vapor concentration in a gas and can be used, for example, to calibrate sensitive elements during corrosion tests.
Известно устройство дл создани парогазовой смеси, содержащее камеру и натекатель.A device for creating a vapor-gas mixture is known, comprising a chamber and a leak.
Недостатком известного устройства вл етс непосто нство концентрации пара во времени за счет влений сорбции на стенках и облитерации.A disadvantage of the known device is the inconvenience of vapor concentration in time due to sorption effects on the walls and obliteration.
Дл уменьшени изменени концентрации нара во времени в предлагаемом устройстве внутренн поверхность камеры покрыта поглощающим пары веществом, например сидикагелем , а натекатель размещен в центре камеры .In order to reduce the change in the concentration of time in the proposed device, the inner surface of the chamber is covered with a substance that absorbs a pair, such as cider gel, and the leak is placed in the center of the chamber.
На чертеже дана схема описываемого устройства .The drawing is a diagram of the described device.
Внутри камеры 1 со стенкой 2 из вещества с неограниченной сорбционной емкостью, например из силикагел , расположены монтажные колодки 3, чувствительные элементы 4 и натекатель 5; один конец последнего соединен с емкостью 6 дл жидкости, концентрацию паров которой необходимо создать. Внутренний диаметр натекател выбран из услови исключени вли ни на процесс диффузии сорбции на стенках к облитерации. Контроль температуры жидкости осуществл етс датчиком температуры 7, а термостатирование при низкой температуре - при помощи сосуда Дьюара 8, например, с жидким азотом.Inside the chamber 1 with a wall 2 of a substance with an unlimited sorption capacity, for example, of silica gel, are mounting pads 3, sensitive elements 4 and leaking 5; one end of the latter is connected to the reservoir 6 for the liquid whose vapor concentration is to be created. The internal diameter of the collector is chosen from the condition of excluding the influence on the process of sorption on the walls to obliterate. The temperature of the liquid is controlled by a temperature sensor 7, and temperature controlled at a low temperature by means of a Dewar 8, for example, with liquid nitrogen.
Так как распространение паров от натекател 5 в объем подчин етс законам молекул рной диффузии, а стенки 2 камеры 1 вл ютс поглощающими (отражение от стенок отсутствует), то вокруг натекател устанавливаетс стационарное сферическое симметричное поле концентраций, определ емое производительностью натекател . Производительность натекател определ етс температурой поверхности жидкости. Изменение температуры поверхности жидкости осуществл етс за счет изменени глубины погружени емкости 6 с жидкостью в сосуд Дьюара 8.Since the propagation of vapors from the collector 5 into the volume is governed by the laws of molecular diffusion, and the walls 2 of the chamber 1 are absorbing (there is no reflection from the walls), a stationary spherical symmetric field of concentrations is established around the collector, determined by the leak performance. The performance of the drip pan is determined by the temperature of the surface of the liquid. The temperature change of the surface of the liquid is carried out by changing the depth of immersion of the container 6 with the liquid in the Dewar vessel 8.
Предмет изобретени Subject invention
Устройство дл создани заданной концентрации пара в газе, содержащее камеру, например , из коррозионно-стойкого сплава ААЩ-АМ и натекатель, герметично вставленный в камеру, отличающеес тем, что, с целью уменьшени изменени концентрации пара во времени, внутренн поверхность камеры покрыта поглощающим пары веществом, например силикагелем, а выход натекател размещен в центре камеры.A device for creating a predetermined concentration of steam in a gas, comprising a chamber, for example, of corrosion-resistant AACH-AM alloy and a leak, which is hermetically inserted into the chamber, characterized in that, in order to reduce the change in vapor concentration over time, the inner surface of the chamber is covered with absorbing vapor a substance, such as silica gel, and the outlet is placed in the center of the chamber.
