Description

Technical Field

[0001] The utility model relates to the technical field of well manifolds, and is a rotary multi-diameter adjustable oil nozzle device. Background Art

[0002] At present, in the process of oil and gas testing in oil fields, a nozzle manifold is usually used for throttling and pressure reduction. The fixed nozzle device used in the nozzle manifold needs to replace the nozzles many times during use. In the prior art, when the nozzle needs to be replaced, another channel of the nozzle manifold needs to be opened and the channel in use needs to be closed, so as to switch to another fixed nozzle process. When it is necessary to switch to a new nozzle again, it is necessary to relieve the pressure on the closed channel and replace the nozzle. The original nozzle is replaced by disassembling the fixed nozzle device, and the required nozzle is replaced. The work is completed by switching the process again, and the process is repeated in this way to achieve multiple nozzle replacements. Therefore, since the fixed nozzle device has only one size of nozzle specification, when replacing it, it is necessary not only to adjust the process of the nozzle manifold and then disassemble and replace the nozzle online, which is time-consuming and labor-intensive, but also affects the normal trial production work and causes certain environmental pollution. Summary of the invention
