Description

Technical Field

[0001] The invention relates to the technical field of oil production, in particular to a sedimentation and sewage discharge mechanism for an oil production valve. Background Art

[0002] The extracted oil contains sand, cement blocks, rubber fragments, operational impurities, etc. When the oil flows slowly, it will produce sediments, affecting the flowability of the pipeline for the oil.

[0003] In the prior art, oil extraction valves do not have the function of discharging sewage. Impurities in the oil are deposited on the valve core of the valve, which will cause greater friction when the valve core rotates, causing damage to the sealing of the valve core, thereby shortening the service life of the valve. At the same time, the impurities in the oil are deposited on the valve and affect the flowability of the valve. When the process is switched, the valve will not close tightly, affecting the process modification construction or other operations, and affecting the normal production of crude oil gathering and transportation.
