一、前言近年来,机械设备向大型、高速、高精度方向发展。随之对油压系统提出了高压、大流量,高速、高频率切模及小型化的要求。而原用的滑阀式油压系统,在振动、噪音、管路损裂、漏油以及耐振、耐冲击、耐久性等方面已达极限。适应上述要求,出现了被称为插装式阀(一种两个方向嵌入的锥阀式逻辑元件——亦有称:锥阀、浮式阀、装弹式阀、插式阀、嵌入式阀等)可组成的油压逻辑系统。数个插装式阀装入集成块内,便具有各种液压元件的
I. Introduction In recent years, machinery and equipment to large-scale, high-speed, high-precision direction. Then the hydraulic system put forward the requirements of high pressure, high flow rate, high speed, high frequency die cutting and miniaturization. The original spool valve hydraulic system, vibration, noise, pipeline rupture, oil spills and vibration, impact resistance, durability has reached the limit. To meet the above requirements, there has been called a cartridge valve (a two-directional cone valve embedded logic - also known as: cone valve, floating valve, pop-up valve, plug-in valve, Valves, etc.) can be composed of hydraulic logic system. Several cartridge-type valve into the manifold, it will have a variety of hydraulic components
