Abstract

本实用新型公开了一种联锁阀,属于液压阀;旨在提供一种结构简单、安全可靠性高,用于矿井提升机制动系统的联锁阀。它包括设有阀腔的阀体、设置在该阀腔中的弹簧及活塞销,设置在该阀体上的进油道和出油道与所述阀腔连通;进油道(12)与出油道(9)之间通过旁路油道(11)连接,在该旁路油道中设有由钢球(10)和小弹簧(8)构成的单向阀。本实用新型是矿井提升机制动系统不可缺少的液压阀。

Description

联锁阀
技术领域:本实用新型涉及一种液压阀,尤其涉及一种联锁阀。
背景技术:联锁阀是矿井提升机制动系统中的关键部件,其可靠性的好坏直接影响到整个设备能否安全正常运行。目前,矿井提升机制动系统所采用的联锁阀主要存在结构复杂、安全可靠性差等缺陷。
发明内容:针对现有技术中存在的上述缺陷,本实用新型旨在提供一种结构简单、安全可靠性高的联锁阀。
为了实现上述目的,本实用新型采用以下技术方案:它包括设有阀腔的阀体、设置在该阀腔中的弹簧及活塞销,设置在该阀体上的进油道和出油道与所述阀腔连通;进油道与出油道之间通过旁路油道连接,在该旁路油道中设有由钢球和小弹簧构成的单向阀。
与现有技术比较,本实用新型由于采用了上述技术方案,因此具有结构简单、锁闭安全可靠等优点。
附图说明:
图1是本实用新型的结构示意图;
图2是图1中俯视图;
图3是图1中左视图。
图中:阀体1  大螺塞2  弹簧3  无杆腔4  活塞销5  有杆腔6  小螺塞7  小弹簧8  出油道9  钢球10  旁路油道11  进油道12
具体实施方式:下面结合附图和具体的实施例对本实用新型作进一步说明:
在图1~3中,阀体1中设有阀腔,弹簧3和活塞销5设置在该阀腔中,活塞销5将该阀腔分隔为无杆腔4和有杆腔6两个部分;设在阀体1中的进油道12、出油道9分别与无杆腔4、有杆腔6连通,进油道12和出油道9之间通过设在阀体1中的旁路油道11连接,该旁路油道中设有由钢球10和小弹簧8构成的单向阀。为了便于调节弹簧的压力,在所述阀腔中设有大螺塞2,在旁路油道11中设有小螺塞7。
