Переключающее устройство блока предохранительных клапанов, содержащее корпус с входным каналом и двумя выходными каналами, имеющими соосно расположенные седла, между которыми и на одной оси с ними расположен затвор двустороннего действия, взаимодействующий с ним шток, кинематически связанный со штоком привод, а каждый из выходных каналов соединен с входом предохранительного клапана, отличающееся тем, что затвор выполнен в виде подпружиненных впускных клапанов и клапана двустороннего действия, которые концентрично расположены к штоку и взаимодействуют в заданной последовательности между собой и штоком посредством жестко связанного со штоком упора, при этом, эффективная площадь впускных клапанов меньше эффективной площади клапана двустороннего действия, который, а также взаимодействующие с ним седла выполнены конусообразными.The switching device of the safety valve block, comprising a housing with an input channel and two output channels having coaxially located seats, between which and on the same axis there is a double-acting shutter, a rod interacting with it, a drive kinematically connected to the rod, and each of the output channels connected to the inlet of the safety valve, characterized in that the shutter is made in the form of spring-loaded intake valves and double-acting valves, which are concentrically located to the stem and interact in a predetermined sequence between themselves and the stem by means of a stop rigidly connected to the stem, while the effective area of the intake valves is less than the effective area of the double-acting valve, which, as well as the saddles interacting with it, are conical.
