一种小吨位叉车液压制动阀的分析研究

Analysis and Research of Hydraulic Brake Valve for a Kind of Small Tonnage Forklift

该文阐述了小吨位叉车制动升级的实现方式,重点阐明HCZF15阀所提供的全动力液压制动系统的优势性能和特点。介绍了HCZF15制动阀的液压原理,阐述了该阀制动压力与操作力的关系特性,包含P口有无供油二种情况;提供了P口流量变化、N口有无转向和Br口有无负载时T口渗漏的关系特点,显示该阀为液压制动系统优势元件,为叉车全方位液压动力制动提供了更多的选择。

This paper describes the implementation way of small tonnage forklift brake upgrade,focusing HCZF 15 valve offers the advantages of full-power hydraulic brake system performance and features.Describes the HCZF15 brake valve hydraulic principle,this paper expounds the relationship between characteristics of the brake pressure and valve operating force,the containing P mouth with or without oil supply two kinds of circumstances; Provides the P mouth flow rate,N mouth have with or without turn around the direction and Br mouth with and without load to the relationship character for T mouth leakage characteristics,shows the valve for a hydraulic brake system components for forklift full hydraulic power brake provides more selection mode.
