Embodiment Construction

[0017] The present invention adopts two two-position three-way electromagnetic ball valves with small flow rate as pilot control valves, and adopts the method of inserting and adding a cover plate to connect four sets of cone valve-type two-way inserting assemblies with the same structure through holes opened inside the valve body. , the pilot control valve controls the opening or closing of the valve ports of each cartridge assembly, thereby changing the communication mode of the four valve ports P, A, B, and T of the three-position four-way electromagnetic reversing valve to realize the reversing function. The specific implementation will be further described below in conjunction with the accompanying drawings:

[0018]The present invention consists of two pilot control valves (a, b), four sets of plug-in components (c, d, e, f), two control cover plates (1, 2) and one plug-in block (3), each The plug-in assembly includes a valve core (10), a valve sleeve (9), a spring (5) a...

Abstract

The invention provides a three-position four-way water pressure magnetic exchange valve used in a deep sea and relates to a component which controls a liquid flow direction in a hydraulic system. The three-position four-way water pressure magnetic exchange valve used in the deep sea is composed of two guide control valves, four sets of insertion components, two control cover plates and an insertion block. Each set of insertion component comprises a valve core, a valve sleeve, a spring and a sealing piece combination. Four sets of cone-valve-shaped two-way insertion components which are in the same structure are mutually communicated through ducts which are formed in the inner portion of a valve body by utilizing a method of plug-in mounting plus cover plates. The guide control valves control the opening or closing of each valve opening of each insertion component, and therefore a communication mode of four valve openings including a P valve opening, an A valve opening, a B valve opening and a T valve opening of the three-position four-way magnetic exchange valve is changed, and reversing function is achieved. The three-position four-way water pressure magnetic exchange valve used in the deep sea is suitable for a liquid flow direction control situation of middle and high pressure aqueous media (fresh sea water, seawater base and the like) and is particularly suitable for being used in a deep-sea mass-flow water hydraulic transmission system.

Description

technical field [0001] The invention belongs to the field of fluid transmission and control, and relates to a component for controlling the direction of liquid flow in a water hydraulic system, which is a water hydraulic three-position four-way reversing valve, suitable for medium and high pressure water media (fresh sea water, sea water base, etc.) For liquid flow direction control occasions, it is especially suitable for use in deep sea large flow water hydraulic transmission systems. Background technique [0002] In addition to the advantages of traditional hydraulic transmission such as compact structure, large power-to-mass ratio, and good stability, water hydraulic transmission technology also has the advantages of no pollution, good flame retardancy, and wide source of media. It is widely used in food processing, marine resource exploration and development. , naval equipment and other fields have unique advantages, and the application prospect is very broad. However,...
