Abstract
Изобретение относитс к области автоматики и может быть использовано дл автоматического перекрыти газопровода при резком падении давлени . Цель изобретени - повышение надежности. Цель достигаетс за счет установки в цилиндрическом корпусе, разделенном перегородкой на полости , чувствительного элемента в виде двух поршней, соединенных штоком и образуюш,их с перегородкой и корпусом четыре камеры, перва из которых соединена с атмосферой, втора - с входным каналом, треть - с четвертой через дроссель, причем треть и четверта камеры заполнены жидкостью и четверта камера соединена с выходным каналом, соединенным с релейным элементом . Датчик выдает сигнал резкого снижени давлени в контролируемой системе. 1 ил. The invention relates to the field of automation and can be used to automatically shut off a pipeline with a sharp drop in pressure. The purpose of the invention is to increase reliability. The goal is achieved by installing in a cylindrical housing divided by a partition on a cavity, a sensing element in the form of two pistons connected by a rod and forming four chambers with a partition and a housing, the first of which is connected to the atmosphere, the second to the inlet channel the fourth through the throttle, with the third and fourth chambers filled with liquid and the fourth chamber connected to the output channel connected to the relay element. The sensor generates a sharp pressure drop in the monitored system. 1 il.
