Abstract

PURPOSE: To save parts and manufacturing processes and reduce the cost of a spherical valve, by setting an auxiliary seal ring on the external side of a main seal ring for taking double sealing effect in a single position.
CONSTITUTION: An auxiliary seal ring 11 is fitted on the external side of main seal ring 7, its external circumference being covered with a valve shell 1 and seal casing 3. The auxiliary seal ring 11 is pressed to a valve body 2 through a contact face C', due to the pressure of liquid which is fed in a liquid chamber 12 formed between the ring 11 and the seal ring 3, and cuts off the liquid flow P. For keeping the seal ring 7 separated from the valve body 2, a liquid passage 10 is connected with a pressrue discharge port and the liquid is fed in the pressure liquid chamber 14 from another liquid passage 15.
