Abstract

FIELD: valving. SUBSTANCE: seat of the unit housing is composed of two axially alined bushings mounted with a spaced relation to each other. The gate of the unit is made up as two plates tightly mounted one inside the other. The outer plate is spring-loaded and fixed to the rod. The inner plate is spring-loaded and coupled with the rod and the outer plate for permitting relative movement. The rod is connected with the piston of the drive for permitting mutual flexible movement when the piston moves along the axis of the drive in both directions. EFFECT: enhanced reliability.

Изобретение относится к арматуростроению, к предохранительной арматуре и может быть использовано в системах безопасности АЭС и ТЭС, предприятий химической и нефтегазовой промышленности. Технический результат - повышение надежности и обеспечение контролируемости характеристик предохранительной арматуры в режимах нормальной работы защищаемого объекта - достигается тем, что седло корпуса арматурного блока разгерметизации составлено из двух коаксиально расположенных втулок с зазором между ними, затвор блока выполнен в виде двух герметичных относительно друг друга тарелей, установленных одна в другой, при этом наружная тарель соединена со штоком неподвижно, а внутренняя тарель подпружинена и соединена со штоком и с внешней тарелью с возможностью относительного перемещения, а соединение штока с поршнем привода выполнено с возможностью взаимного упругого перемещения при движении поршня в обе стороны по оси привода.The invention relates to valve engineering, to safety valves and can be used in the safety systems of nuclear power plants and thermal power plants, enterprises of the chemical and oil and gas industry. The technical result - improving the reliability and ensuring the controllability of the characteristics of safety valves in the normal operation of the protected object - is achieved by the fact that the seat of the housing of the reinforcement depressurization unit is composed of two coaxially located bushings with a gap between them, the shutter of the block is made in the form of two plates sealed relative to each other, installed one into the other, while the outer plate is connected to the rod motionlessly, and the inner plate is spring-loaded and connected to the rod and to the outer her plate with the possibility of relative movement, and the connection of the rod with the piston of the actuator is made with the possibility of mutual elastic movement when the piston moves in both directions along the axis of the actuator.
