气动元件流量特性的表示方法和测定方法,尚未形成统一标准。目前国内使用K(?)值或S 值表示气动元件流量特性,但测定方法不够准确和方便。国际标准化组织(ISO)起草了“气动元件流量特性标准建议草案”,本文予以分析和介绍,作为制订我国有关标准的参考。
Pneumatic components of the flow characteristics of the method of expression and determination, has not yet formed a unified standard. At present, K (?) Value or S value is used to indicate the flow characteristics of pneumatic components, but the measurement method is not accurate and convenient. The International Organization for Standardization (ISO) has drafted the Draft Proposal for Standards of Flow Characteristics of Pneumatic Components, which is analyzed and introduced in this paper as a reference for formulating relevant standards in our country.
