Description

一种升降式止回阀
所属技术领域
本实用新型涉及一种阀门,尤其是一种升降式止回阀。
背景技术
目前在工业系统使用的升降式止回阀,用于控制管道介质的单向流动,以防止介质的倒流。在介质倒流时,由于介质压力的作用下,阀门快速关闭,易产生水锤,对阀门及系统其他设备造成损害。
发明内容
为了克服现有升降式止回阀关闭快,易产生水锤,损害阀门及其他设备的不足,本实用新型提供一种带缓冲的升降式止回阀。
本实用新型解决其技术问题所采用的技术方案是:一种升降式止回阀,包括阀体、阀芯、阀瓣、阀座、轴承,阀芯通过螺钉固定在阀体上,阀瓣通过轴承支承于阀芯内,阀瓣与阀体之间通过阀座密封,在阀芯上固定有盖板,在阀瓣上端有垫块,在垫块与盖板之间装有弹簧。
本实用新型的有益效果是结构简单,缓闭效果好,有效地减少了水锤对设备的危害。
附图说明
图1是实施例的剖面构造图
图中:1.阀体;2.阀芯;3.盖板;4.弹簧;5.垫块;6.轴承;7.阀瓣;8.阀座。
具体实施方式
如图1所示,一种升降式止回阀,包括阀体1、阀芯2、阀瓣7、阀座8、轴承6,阀芯2通过螺钉固定在阀体1上,阀瓣7通过轴承6支承于阀芯2内,阀瓣7与阀体1之间通过阀座8密封,在阀芯2上固定有盖板3,在阀瓣7上端有垫块5,在垫块5与盖板3之间装有弹簧4。由于弹簧4的存在,在介质倒流时缓闭效果好,有效地减少了水锤对设备的危害。
