Title: Prevention of entry of foreign substance into ball valve
Inventor: SEIKE YAJIYUUROU
IPC: F16K5/06
Filed: 1981-10-31
Abstract: PURPOSE:To prevent the slide section between a sealing packing and the surface of a ball of the titled valve from being scratched by the foreign substance by a method wherein the foreign substance such as a powdered material is prevented from entering the gap between the surface of the ball and the inner circumferential surface of a casing. CONSTITUTION:The movement of the foreign substance is checked by the slide surfaces of fins 10 embedded in the inner surface of the sealing packing 5 and the slide surface of the ball 2 of the ball valve. Further, when an inert gas is supplied into the valve from a fluid supply hole 12 in the casing 4, the inert gas blows out from a fluid injection port 13 toward the inside of the valve through the small gap between the slide surfaces of the fins 10 and the slide surface of the ball 2 of the ball valve. Consequently, the movement of the foreign substance  is checked and the foreign substance is transferred into a passage 1 formed in the ball valve, whereby the slide section between the surface of the top end of the sealing packing 5 and the ball 2 of the ball valve is prevented from being scratched by the foreign substance which enters therein.

Filed: 1981-10-30
Abstract: PURPOSE:To reduce probability of a fact that a current comes not to be outputted, by operating the second current mirror circuit even if an input current to the first mirror circuit is cut off and a current is not outputted from a current output terminal. CONSTITUTION:When a current I0 does not flow due to a fault, a current does not flow to pnp transistors 42-45 for constituting the first current mirror circuit 46, either. A current does not flow to a pnp transistor 52, either, the voltage  drop becomes ''0'', the base voltage of a pnp transistor 72 is set to voltage of a  high potential applying point by a resistance 73, the base-emitter voltage becomes ''0'', and the pnp transistor 72 becomes an off-state. As a result, the bases  of pnp transistors 61-65 are released, and to the second current mirror circuit  66, an input current flows through a resistance 74. Accordingly, to I1-I4, each  equal current I11-I14 is outputted through terminals 54-57 from the second current mirror circuit 66.
