Description

改进型板式单向阀
技术领域
本实用新型涉及一种液压阀,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
本实用新型的目的是:提供一种改进型板式单向阀,无泄漏,耐高压,性能稳定。
本实用新型的技术解决方案是: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。
本实用新型结构简单,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为本实用新型的结构示意图。
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。
