Multi-way valve

Abstract

The invention belongs to the technical field of metering management on yield of oil fields and discloses a multi-way valve which comprises an allocator, an allocation disc, a metering channel and an allocation rotating arm, wherein the allocator is of a sealed structure and is provided with a plurality of first inlet tubes; the allocation disc is fixedly connected to the interior of the allocator; the metering channel is formed in one side of the allocation disc; the allocation rotating arm is rotationally arranged on the other side of the allocation disc; the first inlet tubes are communicated with oil well pipelines through ball valves; tube holes communicated with the first inlet tubes in a one-to-one correspondence manner are formed in the allocation disc; a U-shaped channel is formed inside the allocation rotating arm; one end of the U-shaped channel is in dynamic sealing communication with the metering channel; the other end of the U-shaped channel is in dynamic sealing communication with one end in which one tube hole is not communicated with the first inlet tubes. By adopting the structure, the purposes of yield measurement on single oil wells of well stations, total yield measurement on multiple wells and accumulated yield measurement are achieved, and the problems that in the prior art the cost is relatively high as a metering device is independently arranged on each single well, the ball valves are inconvenient to operate when being arranged externally and a large space is occupied are solved.

Description

technical field [0001] The invention relates to the technical field of metering management of oil field output, in particular to a multi-channel valve. Background technique [0002] At present, each well station in most oil fields manages the production capacity of their respective oil wells mostly in a single-line management. Usually, a well station has multiple oil production wells, ranging from 5 to 8 to as many as 10 to 20. In order to measure the output of each single well, a metering device needs to be installed on each single well, which results in higher management costs for the entire management network. The pipelines required for the liquid that does not need to be metered are all arranged outside the cavity, resulting in a large and easily damaged whole system. There are also oil well production management through vertical multi-channel valves in China, but the sub-control valves of existing vertical multi-channel valves are operated by peripheral pipelines, whic...
