插装阀控制技术由于其标准化、系列化、通用化,体积小、性能高等一系列特点,正在得到日益广泛的应用。插装阀阀体有三种型式,即组合式、集成式、整体式,但其中唯有按系统实际需要进行设计的整体式阀体,才能最大限度地利用插装阀的多功能性,而且结构最紧凑,流阻小,响应快,因此国外一些著名液压件公司都倾向于采用整体式阀体。但是整体式阀体孔系复杂,一般孔数常在50到100个左右,少数甚至达到近300个孔。如此复杂的孔系成了设计的难
Cartridge valve control technology because of its standardization, serialization, generalization, small size, high performance and a series of features, is being increasingly widely used. Cartridge valve body there are three types, namely, modular, integrated, monolithic, but only one of the system according to the actual needs of the overall design of the valve body, in order to maximize the use of cartridge valve versatility, and structure Most compact, small flow resistance, fast response, so some well-known foreign hydraulic parts companies tend to adopt the integral body. However, the integral valve body hole complex, the general number of holes often 50 to 100 or so, a few even reached nearly 300 holes. Such a complex hole has become a design difficult
