VALVE BALL VALVE Russian patent published in 2017 - IPC F16K1/14 F16K15/04 

FIELD: machine engineering.

SUBSTANCE: ball valve body is made with an internal cavity, with through radial cylindrical holes, the surface of which is in contact with the fixing elements, and a locking element rigidly fixed on the side of the outer stepped side surface of the housing. The elastic element is fixed to the body by means of a movable clutch with an internal cavity formed by a conical surface of the bore, passing into a cylindrical surface in contact with the fixing elements, which stepwise passes into another cylindrical surface of a larger diameter. On the lower end side, the sleeve is provided with a through groove, commensurate with the width of the locking element of the housing. The movable clutch is fixed to the body by means of a locking ring. The body is equipped with a rod. The stem is formed with an outlet fitting in the upper part, with an annular groove, the surface of which contacts the fixing elements, and with through holes in the lower part forming an inner central channel. An adapter is installed on the side of the inlet choke of the housing. The adapter is made with an outlet fitting and a seat with a ball locking element that covers the passage opening. The longitudinal grooves are made from the end surface of the outlet socket of the adapter.

EFFECT: ensuring operative shutdown of the flow of the working fluid and shutting off the ball valve from the device of the pneumatic equipment.
