一种静力加载保护模块

Static loading protection module

Abstract

本实用新型涉及一种静力加载保护模块,属于静力加载保护模块结构技术领域。包括集成在阀块上的高压过滤器、电液伺服阀以及分别受控于两个电磁换向阀Ⅰ的逻辑阀a及逻辑阀b、受控于两个电磁换向阀Ⅱ的逻辑阀c、逻辑阀d,阀块上还设有进油接头、出油接头以及与作动筒的两个负载腔相连通的接头Ⅰ、接头Ⅱ,其中,电磁换向阀Ⅰ与电磁换向阀Ⅱ的导通状态相反。本实用新型消除卸载振动,互换性好,体积小,安装方便。
The utility model relates to a static loading protection module, and belongs to the technical field of static loading protection module structures. The static loading protection module comprises a high-pressure filter, an electro-hydraulic servo valve, a logical valve a, a logical valve b, a logical valve c and a logical valve d which are integrated on a valve block, wherein the logical valve a and the logical valve b are controlled by two electromagnetic directional valves I respectively, and the logical valve c and the logical valve d are controlled by two electromagnetic directional valves II respectively. The valve block is further provided with an oil inlet connector, an oil outlet connector, and a connector I and a connector II which are communicated with two load cavities of an actuator cylinder. The electromagnetic directional valves I and the electromagnetic directional valves II are opposite in conducting state. The static loading protection module eliminates unloading vibration, and is high in interchangeability, small in size and convenient to install.
