Description

液压支架用双向活塞密封圈
一、技术领域
本实用新型涉及一种液压支架用双向活塞密封圈，其是应用于工程机械、煤矿机械等液压缸双向活塞密封圈。
二、背景技术
现有传统液压缸支架用双向活塞用密封圈，普遍采用分体式(PU)聚氨酯主密封、(NBR)丁腈橡胶弹性体、(POM)聚甲醛导向环组合密封。虽然结构简单，制造方便.但由于结构上的功能互补性差，产品强度、耐磨性、耐冲击性差，使用寿命短，影响液压支架活塞主密封的可靠性，维修更换频次多.严重影响工程机械、煤矿机械等生产效率和安全生产.
三、实用新型内容
本实用新型的目的是提供一种液压支架用双向活塞密封圈，其为双向活塞用密封圈结构，主要用于工程机械、煤矿机械等液压缸双向活塞用密封圈，它可将液压支架用千斤顶下腔向上腔漏液现象消除，保压性指标可提高百分之九十，产品寿命可延长百分之五十。
本实用新型的目的是这样来实现的：一种液压支架用双向活塞密封圈，它包括：导向环，挡圈，弹性体，密封主体，密封主体位于矩形沟槽中间，导向环、挡圈安装于密封主体两侧，弹性体镶嵌于密封主体内；所述的导向环为酚醛树脂夹布材料，挡圈为POM材料，弹性体为NBR材料，密封主体为HPU材料。
本实用新型是采用具有高耐磨和高强度性能的聚氨酯材料(HPU)，利用最新的CNC控制即时密封件制造设备生产，产品已广泛的用于工程机械、矿山机械等液压缸中。
本实用新型液压支架用双向活塞密封圈，其密封主体位于矩形沟槽中间，导向环、挡圈安装于密封主体两侧，弹性体镶嵌于密封主体内。结构紧凑、位置互锁、弹力均匀，密封强劲；分体式导向结构使导向和挡圈分体，挡圈保护聚氨酯密封主体耐高压冲击，导向环采用耐磨性、耐腐蚀更好的酚醛树脂夹布材料。
四、附图说明
附图1为本实用新型结构示意图。
附图2为附图1的剖视图。
附图标记说明如下：
导向环1，挡圈2，弹性体3，密封主体4。
五、具体实施方式
下面结合附图及实施例来对本实用新型做进一步说细描述。
参照附图，本实用新型液压支架用双向活塞密封圈，它包括：导向环1，挡圈2，弹性体3，密封主体4，密封主体4位于矩形沟槽中间，导向环1、挡圈2安装于密封主体4两侧，弹性体3镶嵌于密封主体4内；所述的导向环1为酚醛树脂夹布材料，挡圈2为POM材料，弹性体3为NBR材料，密封主体4为HPU材料。
本实用新型采用国际先进的高精密CNC数控加工技术，一次加工成型，绿色节能，高效环保。本实用新型结构紧凑、弹力均匀，密封强劲；分体式导向结构使导向和挡圈分体，挡圈保护聚氨酯密封主体耐高压冲击，酚醛树脂夹布材料导向环耐磨性、耐腐蚀更好的。
