Abstract

The invention discloses a plate-type four-position four-way cone valve direct-acting electromagnetic reversing hydraulic valve, which comprises a valve body, and a first valve core assembly and a second valve core assembly of a cone valve structure are arranged on both sides of the valve body , the third spool assembly and the fourth spool assembly, and the other two sides of the valve body are respectively equipped with a first electromagnet and a second electromagnet. , different from the existing technology, its two electromagnets can be energized at the same time, adding a function to meet special needs, and the valve core assembly is a cone valve structure, which can achieve nominal zero leakage of the four oil ports, and at the same time The spool assembly is four sets of independent parts. Through different combinations of oil circuits, other non-leakage valve types can be derived. At the same time, the external dimensions are basically the same as those of ordinary spool valves.

Description

A plate type four-position four-way poppet valve direct-acting electromagnetic reversing hydraulic valve technical field The present invention relates to electromagnetic hydraulic reversing valve technical field, be specifically a kind of plate type four-position four-way cone valve direct-acting electromagnetic Reversing hydraulic valve. Background technique

[0002] Plate type electromagnetic reversing hydraulic pressure in accordance with DIN 24 340-A6 / DIN 24 340-A10 industrial standard connection mounting surface Valves, commonly known as 6- and 10-diameter plate solenoid valves, are widely used in hydraulic systems, according to the shape of the spool. Type, usually divided into slide valve type and poppet valve type, slide valve type is a gap seal, there is a certain amount of leakage, poppet valve type is a cone surface Seal or steel ball seal, which can be nominally leak-free, and the poppet valve type is usually realized in the form of lever steel ball type or...
