Hierarchical-depressurizing oil nozzle manifold
2014
The invention relates to the field of oil/gas field blowout work depressurizing and provides a hierarchical-depressurizing oil nozzle manifold which comprises a manifold pipeline, a first adjustable oil nozzle connected with the manifold pipeline through a first flat-plate gate valve, a first fixed oil nozzle connected with the manifold pipeline through a second flat-plate gate valve, a second adjustable oil nozzle and a second fixed oil nozzle. The first adjustable oil nozzle and the first fixed oil nozzle are disposed on two sides of the manifold pipeline respectively, and the second adjustable oil nozzle and the second fixed oil nozzle are disposed on the two sides of the manifold pipeline respectively. By the hierarchical-depressurizing oil nozzle manifold, after multistage depressurizing and multiple pressure adjusting of high-pressure fluid during incoming, connection pressure reduction of a pipeline manifold and other parts is prolonged, or part replacement and maintenance probability is reduced, so that production efficiency is improved; due to preferable processing and careful material selection, technical effect of depressurizing of the manifold is better, and the advantages include but are not limited to that service lives of the above parts are prolonged, depressurizing effect is improved, and performance-cost ratio is high.
