Abstract: An oil and gas collection and transmission system for petroleum, chemical industry, and so on, includes a multi-way valve with a fan-shaped flow channel sealing pair to measure production of an individual well to obtain the dynamic production data of an oil well. The multi-way valve with fan-shaped flow channel sealing pair includes a floating gating ring that is applied with contact specific pressure by an elastic component and an upper porous plane body form a gating plane sealing pair; a plurality of fan-shaped flow channel oil inlet holes are annularly and uniformly distributed on a mating surface of the upper porous plane body; the floating gating ring is configured such that it changes gradually from the upper fan-shaped flow channel to the lower round-shaped flow channel; and the inner part of the middle rotary spool is used as a public flow-guide passage.

Abstract: The present utility model relates to an oil and gas collection and transmission system for petroleum, chemical industry and so on. A multi-way valve with fan-shaped flow channel sealing pair measures in turn the production of an individual well to obtain the dynamic production data of an oil well. The multi-way valve with fan-shaped flow channel sealing pair is characterized in that: a floating gating ring that is applied with contact specific pressure by an elastic component and an upper porous plane body form a gating plane sealing pair; a plurality of fan-shaped flow channel oil inlet holes are annularly and uniformly distributed on a mating surface of the upper porous plane body; the floating gating ring is configured such that it changes gradually from the upper fan-shaped flow channel to the lower round-shaped flow channel; and the inner part of the middle rotary spool is used as a public flow-guide passage.
