SWITCH VALVE FOR SYSTEM OF SAFETY VALVES AND SYSTEM OF SAFETY VALVES Russian patent published in 2019 - IPC F16K11/44 F16K17/00 

FIELD: valve industry.

SUBSTANCE: group of inventions relates to a switching valve for a safety valve system and a safety valve system. Switching valve comprises a valve body having one fluid inlet and two fluid outlets, as well as locking body movable located in valve body, which is arranged with the possibility of movement between two locking positions. In each position, it accordingly closes one of the outlets for fluid medium. Locking body has two facing sealing surfaces. On each of the fluid outlets in the valve body one corresponding valve seat is made, which are made so that one of the sealing surfaces in one of the locking positions, respectively, is in tight contact with one of the valve seats. Locking body is arranged with the possibility of rotation around the rotary axis located outside the locking body and the sealing surfaces. Switching valve has a linear drive, which acts on the locking body, which is radially removed from its rotary axis and which is conjugated with the locking body so that the locking body is made with possibility of rotation between its locking positions by means of the linear drive movement.

EFFECT: switching valve for system of safety valves has good flow characteristics, as well as a large field of application.
