一、液压系统向高压大流量发展的必然后果之一,是从根本上改变系统中滑阀式方向阀的传统结构,使它演化成插装式座阀的形状(图卜1)。这种新型式的阀具有很多优点,主要有下列三个方面〔1)
First, one of the inevitable consequences of the development of high pressure and high pressure hydraulic system is to fundamentally change the traditional structure of the spool valve to evolve into the shape of the plug-in seat valve (Figure 1). This new type of valve has many advantages, mainly in the following three aspects [1]
