Abstract

一种二位三通手动阀,涉及超高压液压系统的液压控制阀。它包括阀座、阀块,阀座与阀块之间设有连接套,其主要技术特征是阀块内设有弹簧,弹簧连阀芯,阀芯连顶杆,顶杆上连有单向阀,单向阀连接手柄;所述阀芯油路通进油口P,单向阀油路通道连出油口A,阀体内还设有通气口L。本实用新型既能防止千斤顶工作时,油管意外破裂,保证千斤顶长期处于锁住状态,并且同时可拆卸压力表,用于其它地方测量。

Description

二位三通手动阀 
技术领域:
本实用新型涉及超高压液压系统的液压控制阀。 
背景技术:
现有的液压系统的液压控制阀只适用于31.5MP,当压力大于70MP时,就需要相适应的液压控制阀。而且每个装置都需要配有液压控制阀,成本高。 
发明内容:
本实用新型提供一种保证千斤顶长期处于锁住状态,并且可通用的二位三通手动阀。 
本实用新型是通过如下技术方案来实现的:一种二位三通手动阀,包括阀座、阀块,阀座与阀块之间设有连接套,其主要技术特征是阀块内设有弹簧,弹簧连阀芯,阀芯连顶杆,顶杆上连有单向阀,单向阀连接手柄; 
所述阀芯油路通进油口P,单向阀油路通道连出油口A,阀体内还设有通气口L; 
所述连接套与顶杆之间设有挡圈和O形圈;连接套与阀块之间设有O形圈,单向阀与阀座之间设有O形圈,阀块与堵头之间设有密封垫。 
本实用新型既能防止千斤顶工作时,油管意外破裂,保证千斤顶长期处于锁住状态,并且同时可拆卸压力表,用于其它地方测量。 
附图说明:
图1、图2为本实用新型的结构示意图。 
具体实施方式:
如图1、图2所示,本二位三通手动阀,包括阀座13、阀块10,阀座与阀块之间设有连接套9,阀块内设有弹簧3,弹簧连阀芯4,阀芯连顶杆5,顶杆上连有单向阀12,单向阀连接手柄15;单向阀上有钢球16;阀芯油路通进油口P,单向阀油路通道连出油口A,阀体内还设有通气口L;连接套与顶杆之间设有挡圈 6和O形圈7;连接套与阀块之间设有O形圈8,单向阀与阀座之间设有O形圈11,阀块与堵头1之间设有密封垫2。手柄上设有螺钉14。 
进油口P接工作千斤顶,出油口A接测量压力表,通气口L通大气,进油口P与出油口A相通时,可以测量千斤顶的工作压力,当出油口A与通气口L相通时,把进油口P处千斤顶的压力锁住,同时可以拆卸出油口A处的压力表,用于其他地方测量。
