2D multifunctional two-way valve

Abstract

The invention discloses a 2D multifunctional two-way valve which comprises a 2D valve. A pressure-torsion coupling is arranged on one side of the 2D valve. A proportional electromagnet is arranged onthe side, away from the 2D valve, of the pressure-torsion coupling. The mechanical structure design is simplified, a mechanical structure needed for achieving different functions of an overflow valve,a pressure reduction valve, a flow valve and the like is achieved, and the advantage that the device application range is wide is brought; a valve element and a valve body of the 2D valve are directly assembled (without a valve sleeve), the structure is simple, machining difficulty is greatly reduced, and cost is reduced; through the design of a spherical rolling wheel on a rolling wheel obliquegroove in the pressure-torsion coupling, mechanism friction in the pressure-torsion coupling is reduced, and jamming of a pressure-torsion assembly can be avoided; and the 2D multifunctional two-way valve has the advantages of being small in size, wide in application range and the like.

Description

technical field [0001] The invention relates to a two-way valve, in particular to a 2D multifunctional two-way valve. Background technique [0002] In the late 1960s, with the increasingly close integration of electronic technology (including sensors) and hydraulic technology, the continuous development of engineering applications put forward higher requirements for hydraulic control valves. The performance indicators of various electro-hydraulic proportional control valves with feedback It is becoming more and more perfect, and has the tendency to replace other high-end hydraulic components (such as servo valves). However, the current development status of China's electro-hydraulic proportional valves, especially high-end digital pressure and flow control valves, is not optimistic. The main problems are: (1) The monopoly of foreign hydraulic manufacturers on China's hydraulic industry. Manufacturers, such as Japan Yuken, Rexroth and Vickers, have formed a monopoly position ...
