    摘要: A multi-way valve with fan-shape passage sealing pairs which measures in turn production of individual well to obtain dynamic production data of oil well. The valve relates to oil and gas transmission system for petroleum, chemical industry,and so on.The valve comprising: a floating trigger ring(17),an upper multi-port plane body(10),a middle rotary valve core(5),etc,wherein the ring(17) that is applied with contact pressure by an elastic part and the plane body form selectively flat face sealing pairs,the plane body(10) provides a mating surface with a plurality of fan-shape flow channels for inflowing oil in annular distributor, the ring (17) is configured such that the ring becomes gradually round from fan-shape,the inner part of the valve core(5) is used as public passage. To realize measurement and rotary selecting,the inner public measurement passage of the plane body(10) communicates with one fan-shape channel for inflowing oil provided in the mating surface of the plane body,when the valve core(5) is rotated a certain angle. The sealing face achieves contact pressure self-sealing by pre-forced some elasticity to the ring(17). The valve has compact structure. The flow channel is formed by casting. The sand carried in the liquid does not enter into the sealing face easily. The plane mechanism has low cost, stable sealing, and long life.

    摘要: Disclosed are a valve seat ring (8) and a multi-way valve having the valve seat ring (8). The multi-way valve comprises an upper valve body (1), a lower valve body (2) and a rotary valve core (3), wherein the valve seat ring (8) is located in the rotary valve core (3), the valve seat ring (8) comprises a body (10), the body (10) is provided with a penetrated through-hole (18), a first annular boss (13) is arranged on an outer wall (11) of the body (10), and a second annular boss (14) is arranged on an inner wall (12); the upper surfaces of the first annular boss (13) and the second annular boss (14) are respectively flush with the upper surface of the body (10) to form a sealing surface (15) which fits with a sealing surface (9) of the upper valve body (1) in a sealed manner; and an annular gap is formed between the lower surface of the first annular boss (13) and the rotary valve core (3), so that liquid in the chamber (4) and an oil incoming channel (5) respectively acts on the lower surface of the first annular boss (13) or the second annular boss (14) to form a sealing load. A pressure is applied from either the chamber (4) or a metering orifice (6), a sealing load hydraulically acted on the valve seat ring (8) is formed by the hydraulic acting force of the chamber (4) or the metering orifice (6), and the hydraulic adaptability for sealing the valve seat ring (8) is realized, thereby meeting the requirement of sealing in the multi-way valve at the leakage level of sealing level VI under a high-pressure difference.
