Abstract

本发明公开了一种改进型板式单向阀，该单向阀包括阀盖（1）、阀体（2）、弹簧（3）和锥阀芯（4），阀盖（1）固定阀体（2）上，锥阀芯（4）经弹簧（3）安装在阀体（2）内，整体构成单向阀。本发明结构简单，制造容易，成本低廉，性能稳定，避免阀座脱落造成的阀流量减小或功能失效现象，使用寿命长。

Description

改进型板式单向阀
技术领域
本发明涉及一种液压阀，属于液压机械制造领域，具体涉及改进型板式单向阀。
背景技术
众所周知，板式单向阀只允许油液从一个方向自由流动而不得反向流动，主要用作于泵的出口处或作背压阀或旁路阀用。常规的板式单向阀结构复杂，在加工过程中阀座与阀体过盈量不好控制，加工制造难度较大，在使用过程中容易出现阀座脱落现象造成阀无法打开，阀流量减小或功能失效，导致泵或系统元件损坏，甚至人生安全事故，经济损失巨大。
发明内容
本发明的目的是：提供一种改进型板式单向阀，无泄漏，耐高压，性能稳定。
本发明的技术解决方案是：该单向阀包括阀盖、阀体、弹簧和锥阀芯，阀盖固定阀体上，锥阀芯经弹簧安装在阀体内，整体构成单向阀。
本发明结构简单，制造容易，成本低廉，性能稳定，避免阀座脱落造成的阀流量减小或功能失效现象，使用寿命长。
附图说明
图1为本发明的结构示意图。
图中：1阀盖，2阀体，3弹簧，4锥阀芯。
具体实施方式
如图1所示，该单向阀包括阀盖1、阀体2、弹簧3和锥阀芯4，阀盖1固定阀体2上，锥阀芯4经弹簧3安装在阀体2内，整体构成单向阀。
