VALVE CONTAINING DEVICE FOR JOURNAL MOBILITY EXCLUSION, INSTALLATION OF ENERGY CONVERSION, FLUID DISTRIBUTION NETWORK INCLUDING SUCH VALVE, AND METHOD OF SUCH VALVE DISMOUNTING Russian patent published in 2015 - IPC F16K5/06 F16K5/08 F16K43/00 

FIELD: machine building.

SUBSTANCE: valve (2) contains fluid locking element, that is alternatively put in rotation by the valve actuator, and at least one journal (20), hollow casing (24), in which the locking element (22) can move, and which limits at least one hole (A26) for the journal reception (20), and bearing (31) located around the journal (20) and inside hole (A26) of casing (24), ensuring the journal (20) support and directing of its rotation relatively to the hole (A26), thus centring the journal (20). The valve (2) additionally contains device (30) excluding the journal mobility relatively to the casing (24) of the valve (2) and its sealing. This device (30) is located at the same side of the bearing (31) as the internal volume (V24) of the casing (24), and is made with possibility of movement by means of the bearing (31) to move from unclamped first configuration to the clamped second configuration, where it excludes the journal (20) mobility in the hole (A26), and vice versa. There is also installation for energy conversion, the fluid distribution network, including this valve, and method of this valve dismounting.

EFFECT: increased operation reliability and easy maintenance of the bearing suitable for any type of obturator.
