柱塞泵控制阀制造技术

本实用新型专利技术涉及一种柱塞泵控制阀及其控制方法，由阀体、功率阀部件、流量阀部件、单向阀部件以及调速阀部件组成。功率阀部件与伺服活塞之间设有一通路与流量阀部件并行，即A与B之间设置一通路与流量阀部件并行。本实用新型专利技术的优点是来自功率阀部件的压力油可以避开流量阀部件的干扰，功率变量不会出现等待状态。功率阀部件变量与流量阀部件变量相互独立，避免了功率偏移情况。流量阀部件与阀体间可以做成正遮盖形式，整泵泄露减少，效率提高。同时可实现对功率响应时间的调节。（*该技术在2023年保护过期，可自由使用*）

Piston pump control valve

The utility model relates to a plunger pump control valve and a control method thereof, comprising a valve body, a power valve component, a flow valve component, a one-way valve component and a speed regulating valve component. A passageway is arranged between the power valve component and the servo piston in parallel with the flow valve component, that is, a passageway is arranged between the A and the B in parallel with the flow valve component. The utility model has the advantages that the pressure oil from the power valve component can avoid the interference of the flow valve component, and the power variable can not appear the waiting state. The power valve component variables are independent of the flow valve component variables to avoid power offset. The flow valve component and the valve body can be made into a positive cover form, the whole pump leakage is reduced, and the efficiency is improved. At the same time, the power response time can be adjusted.
