Problems solved by technology

Due to the influence of special and complicated working conditions, it has strict requirements on sealing performance, structural size, service life and other indicators, and the design is difficult. At present, there are no mature products in China, and the products used in the project all rely on foreign imports. Moreover, only the products of foreign non-mainstream manufacturers can be imported, which seriously affects the independent development and localization of domestic deepwater control systems

Abstract

The invention relates to an underwater electro-hydraulic reversing valve. The reversing valve is characterized by comprising a pilot valve protective cover, a pilot valve protective cover sealing sleeve, a pilot valve base, a pilot valve, a pilot valve base sealing sleeve, a conversion spring, a pressing sleeve, a spring base, a sleeve sealing top plate, a first sealing leather bowl, a pressure sensor, a circular section rubber sealing ring, a shell valve module, a second sealing leather bowl and a five-core sealing electric socket. The bushing multi-axle cooperation and different linear contact diameters are maintained through a valve and a shell; and high oil pressure is used for generating acting force to overcome and converse the spring pretightening force to maintain the position of the opened valve, so that the structure is simplified, and the volume and the weight are optimized.

Description

technical field [0001] The invention belongs to the field of high-pressure fluid control and relates to an underwater electro-hydraulic reversing valve. Background technique [0002] The underwater reversing valve is a special reversing valve, which is mainly used in the deep water environment with a depth of 1500 meters to 3000 meters and a working medium pressure of 35 MPa, as an important executive component of the deep water production control system. Due to the influence of special and complicated working conditions, it has strict requirements on sealing performance, structural size, service life and other indicators, and the design is difficult. At present, there are no mature products in China, and the products used in the project all rely on foreign imports. Moreover, only the products of foreign non-mainstream manufacturers can be imported, which seriously affects the independent development and localization of domestic deepwater control systems.
