Problems solved by technology

[0002] The underwater mixed transport booster pump is a deep-sea oil and gas extraction device that directly transports deep-sea oil, gas, water, and sediment impurities to the water surface. The working depth is 1500 meters underwater, and the valve group is used to transport and shut off the fluid. , the existing underwater valve group is basically used for relatively shallow water depth, and it is difficult to meet the water depth requirement of 1500 meters

Embodiment Construction

[0016] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, the installation structure of the electric ball valve for deep sea environment in this embodiment includes a bottom cover 12, a valve body is installed in the upper middle position of the bottom cover 12, and an oil-filled cover is installed on the bottom cover 12 through a sealing strip 10 and bolts 11. 3. The top of the oil-filled cover 3 is installed with the top cover 2 through the same sealing strip 10 and bolts 11; there are threaded holes on the connecting surfaces of both ends of the oil-filled cover 3, and steel pipes 5 and 5 are symmetrically installed in the two threaded holes. Butt-welding flange 1 is installed on the outer end of the steel pipe 5, and a disassembly flange 8 is installed on the inner end of the steel pipe 5. The disassembly flange 8 is connected with the steel pipe 5 through a ...

Abstract

The invention relates to an electric ball valve mounting structure in a deep marine environment. The electric ball valve mounting structure comprises a bottom sealing cover, wherein an electric ball valve body is arranged in the middle of the upper part of the bottom sealing cover; an oil filling cover is arranged on the bottom sealing cover through a sealing strip and a bolt; a top sealing coveris arranged on the top of the oil filling cover through the same sealing strip and bolt; threaded holes are formed in connecting surfaces at two ends of the oil filling cover; steel tubes are symmetrically arranged in the two threaded holes; welding neck flanges are arranged at the outer ends of the steel tubes; dismountable flanges are arranged at the inner ends of the steel tubes and are connected with the steel tubes through bolts; and flange gaskets are arranged at the ends of the dismountable flanges. The electric ball valve mounting structure disclosed by the invention is compact and reasonable and is convenient to operate, and the maximum environment stress of 20MPa can be borne by adopting oil filling design inside deep sea. Due to examination of a pressure cylinder test, the rationality of the design is proved.

Description

technical field [0001] The invention relates to the technical field of deep water underwater oil and gas engineering, in particular to an electric ball valve installation structure used in deep sea environment. Background technique [0002] The underwater mixed transport booster pump is a deep-sea oil and gas extraction device that directly transports deep-sea oil, gas, water, and sediment impurities to the water surface. The working depth is 1500 meters underwater, and the valve group is used to transport and shut off the fluid. , the existing underwater valve group is basically used for relatively shallow water depth, and it is difficult to meet the water depth requirement of 1500 meters. Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the existing production technology, the applicant provides an electric ball valve installation structure for deep sea environment, so as to meet the requirements of use. [0004] The technical scheme adopt...
