Double-cone type two-position four-way electromagnetic reversing valve

Abstract

The invention discloses a double-cone type two-position four-way electromagnetic reversing valve and belongs to a water hydraulic control valve. The double-cone type two-position four-way electromagnetic reversing valve is mainly applicable to a direction control valve of a medium and high-pressure deep sea operating device which takes seawater, fresh water, a high-water base and the like as a working medium and is also applicable to a working condition in an atmospheric environment. The double-cone type two-position four-way electromagnetic reversing valve disclosed by the invention is based on deep sea application and is capable of solving the problems met by a traditional electromagnetic reversing valve working in a deep sea environment at the aspects of overall sealing, pressure compensation, underwater control and the like of the reversing valve; an electromagnetic control device is integrally sealed so as to be isolated from external seawater; meanwhile, a valve opening is sealed by adopting a cone valve, so leakage of the valve opening is reduced; by adopting a separated type double-cone valve structure, the sealing reliability of the valve opening of the reversing valve is guaranteed, and a valve core of the reversing valve is also ensured not to be affected by the value of ambient pressure. The reversing valve disclosed by the invention is small in size, rapid in response, small in leakage, high in work reliability, long in service life, good in economical efficiency, free of pollution, applicable to work under seawater environments different in water depth and quite high in practical application value.

Description

Technical field [0001] The invention relates to a direction control element that can be used in the deep sea, belonging to the valve category, suitable for the fields of oil pressure and water pressure, and mainly suitable for the direction control of medium and high pressure deep sea operation devices using sea water, fresh water, high water base, etc. as working media The valve is also suitable for working conditions in an atmospheric environment. Background technique [0002] my country is a big ocean country, and the vast continental shelf contains rich mineral resources. It is urgent to accelerate the development and utilization of ocean resources. Especially facing the critical period of energy shortage and depletion of available mineral resources, the development of marine resources has become a national strategic focus, which is of great significance to national economic development and social stability. As an important means and tool for ocean exploration and ocean deve...

Problems solved by technology

[0005] The invention provides a double-cone two-position four-way electromagnetic directional valve, which is used to solve the technical problems encountered in the operation of the two-position four-way electromagnetic directional valve in the deep sea environment, and aims to solve the traditional two-position four-way electromagnetic directional valve. When the directional valve works in the deep sea environment, it is not only affected by the depth of seawater, but also has to consider the overall sealing of the directional valve, pressure compensation, and underwater control.
