Description
Предметом изобретени вл етс прибор дл измерени абсолютного давлени в герметических кабинах самолетов и перенада относительно , внешнего атмосферного давлени .The subject of the invention is a device for measuring the absolute pressure in the airtight cabins of airplanes and relative to relative external atmospheric pressure.
Обычно измерение давлени в кабине и нерепада относительно внешнего атмосферного давлени осундествл етс двум отдельными приборами, а именно: а) указателем давлени в кабине, выражаемого в едишщах высоты над уровнем мор но стандартной атмосфере, и б) указателем неренада давлени (дифференциальный манометр).Usually, the measurement of pressure in the cabin and non-failure with respect to the external atmospheric pressure is determined by two separate instruments, namely: a) an indicator of pressure in the cabin, expressed in units of height above the standard atmospheric level, and b) an indication of non-pressure difference (differential pressure gauge).
Предлагаетс прнбор, замер ющий оба указанных параметра.A kit is offered that measures both specified parameters.
Отличительной особенностью прибора вл етс то, что внутренн полость корпуса прибора соединена с полостью кабины самолета, а внутренн полость чувствительного элемента указател перенада давлени соединена с приемником статического атмосферного давлени .A distinctive feature of the device is that the internal cavity of the device body is connected to the cavity of the aircraft cabin, and the internal cavity of the sensitive element of the pressure transfer indicator is connected to the receiver of static atmospheric pressure.
На чертеже изображена обща кинематическа схема прибора.The drawing shows the overall kinematic diagram of the device.
Чувствительным элементом указател давлени вл етс анероидна коробка 1 (пли блок анероидов).The sensitive element of the pressure gauge is the aneroid box 1 (or aneroid block).
Движение нодвижного жесткого центра анероида, в зависимости от изменени абсолютного давлени в кабине, через передаточный механизм передаетс на стрелку 2. Чувствительным элементом указател перепада давлени вл етс снециальна дмембранна коробка 3, внутренн нолость которой сообщаетс через трубопровод 4 со штуцером 5, укрепленным в дне корпуса прибора. СоТедовательно, движение подвижного жесткого центра этой коробки, в зависимости от изменени перепада давлени внутри ее и в корпусе прибора (т. е. в кабине самолета ), через передаточный механизм преобразуетс во вращательное движение второй стрелки прибора 6.The movement of the fixed aneroid center, depending on the change in absolute pressure in the cabin, is transmitted through the transmission mechanism to the arrow 2. The sensitive element of the differential pressure indicator is a special dmembrane box 3, the internal part of which communicates through pipe 4 with fitting 5 fixed to the bottom of the body device. Consequently, the movement of the moving rigid center of this box, depending on the change in pressure difference inside it and in the instrument case (i.e., in the aircraft cabin), through the transmission mechanism is converted into rotational motion of the second arrow of device 6.
Циферблат прибора имеет две шкалы: а) верхнюю - дл отсчета показаний давлени в кабине в единицах высоты над уровнем мор по стандартной атмосфере и б) нижнюю - дл отсчета показаний перепада давлени в кабине относительно атмосферного давлени .The dial of the instrument has two scales: a) the upper one for reading the pressure in the cabin in units of height above sea level in a standard atmosphere, and b) the lower one for reading the pressure drop in the cabin relative to the atmospheric pressure.
