Description

液控单向阀
技术领域
本实用新型涉及一种液控单向阀。 
背景技术
液控单向阀是依靠控制流体压力,可以使单向阀反向流通的阀。这种阀在煤矿机械的液压支护设备中占有较重要的地位,而目前市面上的液控单向阀其内部结构都不够合理、流量也不够大、无法配合国内大支架使用、且性能不够稳定、密封性能也不够好。 
发明内容
本实用新型的目的在于克服现有技术的缺陷,提供一种结构简单合理、密封性好、流量大、适合国内大支架使用、性能稳定的液控单向阀。 
为实现上述目的,本实用新型采用一种液控单向阀,包括阀体、螺堵、活塞、顶杆、隔离套、阀座、阀芯、导套、弹簧与螺套,阀体形成一内腔,所述螺套与螺堵分别固定设置在阀体的左、右两端,导套、阀座、隔离套与活塞自左向右依次设置在阀体的内腔内,阀芯适配设置在导套内,所述弹簧的一端与阀芯压紧,弹簧的另一端与螺套的内壁相抵。 
本实用新型再进一步设置,螺套、螺堵、阀座、活塞四者与阀体的连接处均设置有密封圈。 
综上所述,本实用新型的有益效果是:液控单向阀结构简单可靠,产品整体采用管式,不需要另外加接口,可以直接用四个螺栓固定在阀架上,省去了配液板,且液控单向阀流量大,可以配合国内的大支架使用,并在产品的各部件连接处均设置有密封圈,产品性能稳定、密封性好。 
附图说明
图1是本实用新型实施例的结构示意图。 
具体实施方式
如图1所示,本实用新型的具体实施例是液控单向阀,包括阀体1、螺堵2、活塞3、顶杆4、隔离套5、阀座6、阀芯7、导套8、弹簧9与螺套10,阀体形成一内腔11,所述螺套10与螺堵2分别固定设置在阀体1的左、右两端,导套8、阀座6、隔离套5与活塞3自左向右依次设置在阀体1的内腔11内,阀芯7适配设置在导套8内,所述弹簧9的一端与阀芯7压紧,弹簧9的另一端与螺套10的内壁相抵,螺套10、螺堵2、阀座6、活塞3四者与阀体1的连接处均设置有密封圈a,通过以上设置,液控单向阀结构简单可靠,产品整体采用管式,不需要另外加接口,可以直接用四个螺栓固定在阀架上,省去了配液板,且液控单向阀流量大,可以配合国内的大支架使用,并在产品的各部件连接处均设置有密封圈,产品性能稳定、密封性好。
