气体增压泵对液压控制阀的基本要求

液压控制阀的作用是控制和调节液压系统中油液的流动方向、压力和流量，因此，气体增压泵讲解其在性能上应具备以下几项基本要求：

Hydraulic control valve is the direction of the flow, control and adjust the hydraulic system pressure and flow, therefore, gas booster pump on its should have the following basic requirements in performance:

（1）动作灵敏准确，工作平稳可靠，在调节过程中应无冲击、振动现象产生。

(1) the action is sensitive and accurate, stable and reliable work, in the process of adjustment should have no impact, vibration phenomenon.

（2）油液通过控制阀的压力损失小，效率要高。

(2) the oil pressure control valve through the loss of small, high efficiency.

（3）装配质量高，密封性能好，在额定工作压力下应无外渗漏。

(3) the assembly of high quality, good sealing performance, the working pressure should be no leakage.

（4）扔通用性好，使用寿命长，并且安装检修方便。

(4) throw good versatility, long service life, and convenient installation and maintenance.

除了上述要求外，还应当做到结构简单紧凑、体积小，外形美观大方，并且制造容易，价格便宜。

In addition to the above requirements, should also be simple and compact structure, small volume, beautiful appearance, and easy manufacture, low price.
