我们结合新产品开发,研制了一种小流量单向行程调速阀(以下简称为行程调速阀)。经过实践应用,证明该阀性能优良,不渗漏,同时具有体积小、结构简单、成本低等特点。因此,特别适用于小型移动部件单方向的速度控制。本文就其结构特点、工作原理、主要零件和内泄量的设计计算,以及制造要求介绍如下。 We combine the development of new products, developed a low-flow one-way stroke speed control valve (hereinafter referred to as stroke speed control valve). After practical application, the valve proved excellent performance, no leakage, at the same time with small size, simple structure, low cost and so on. Therefore, it is especially suitable for unidirectional speed control of small moving parts. This article on its structural features, working principle, the main parts and internal volume of the design and calculation, as well as manufacturing requirements are as follows.
