控制阀的控制方式(Mode of control valve)

Eg：2N——总功率控制+负流量控制（Total power control+ Negative flow control）

功率控制与流量控制可以进行组合，上图为其中一种组合，在有某种特殊的需要时，我们将依据您的需求进行设计改进。

Power control and flow control can be combined and applied, and the drawing above shows one solution. Any special requirement, we can design for you

M系列控制阀（M Series）H系列控制阀（H Series）

M系列（P-Q曲线是用双直线 H系列（P-Q曲线是一条相

近似模拟双曲线）对光滑的双曲线）

M Series (P-Q curve: double straight line ) H Series (P-Q curve: smooth hyperbola curve) 博一独立开发的新型液压泵控制阀（H系列），具有以下特性：

调节器采用杠杆力矩平衡原理，能够实现真正的恒功率调节；

创新性的从它泵引入液压油，通过台阶柱塞的双台阶控制，实现双泵交叉总功率控制；

由于采用杠杆力矩平衡原理，可以使弹簧在正常工作中仅在2mm范围内压缩，从而可以大大减小或消除常用功率弹簧在大压缩量时刚度下降对泵恒功率控制的影响，同时可以提高弹簧的使用寿命及稳定性；

采用特有的中位控制阀实现中位节能，使泵在非工作状态时将中位控制阀打

开，泵消耗功率仅为恒功率模式的9%，从而达到降低能耗、节约能源的目的，且控制可靠、方便；

调节器采用全新的结构设计，检修、拆装、维护非常方便（整个装配仅需一支5mm外六角扳手即可完成）。

The new hydraulic pump control valve Boyi company developed has the following characteristics:

1、The regulator employs leverage moment balance principle, which can

achieve the real fixed power control.

2、Creatively lead the hydraulic oil from another pump, to achieve total

power control, through double steps control of step piston.

3、Due to leverage moment balance principle, it can make the springs compress

within 2 mm in normal work situation, greatly reduce or get rid of the fixed power influence caused by common springs in big amount of compression, increase the springs’ life and stability.

4、Special median control valve is used to achieve median energy saving,

which makes the median control valve open when off working, and the consumed power is only 9% of the fixed power, to get consumption reduction and energy saving, easily controlled.

5、The regulator employs brand new structure design, which makes test,

repair, dismounting, assembly and preservation be easy (only a 5 MM outside hex wrench is needed when assembling ).
