AI Technical Summary

Technical Problem

The existing valve disc has a large flow resistance when the volume flow is large, and due to the increase in size, it cannot be adapted to a modular system, which is also costly.

Method used

A valve disc is designed, wherein the diameters of the first and second working interfaces are at least 30% of the distance between the first and second central axis, respectively, by increasing the diameter of the working interface and the diameter of the first main slide valve. , reduce flow resistance and ensure normal operation in a modular system by optimizing the cavity structure and pressure limit valve design.

Benefits of technology

This achieves providing particularly large fluid flow in a modular system, reducing flow resistance, reducing costs, and ensuring adaptability and stability of the valve plate.

Abstract

The invention relates to a valve disk (10) having a first and a second main spool (50; 60), each having a first or a second central axis (51; 61), each of which is provided with a first, a second, a third and a fourth cavity. According to the invention, the first working connection (31) is arranged in the direction of the transverse axis (11) between the first and the second central axis, said first working connection being permanently in fluid-exchange connection with the first and the third cavity, and the second working connection being arranged in the direction of the transverse axis (11) between the first and the second central axis, said second working connection being in fluid-exchange connection with the third cavity. The first and second main slide valves (50; 50 ') are permanently in fluid exchange connection with the second and fourth cavities. 60) can be moved between the first or second working interface (31; 32) and the at least one pump channel or the at least one tank channel such that the dual-acting actuator connected to the first and second working interfaces can be moved in two opposite directions.
