Description
技术领域
本发明涉及热采手动平板阀,具体涉及金属密封热采手动平板闸阀。
背景技术
目前,常规的手动平板闸阀使用温度为:-60~121℃,不能使用在390℃超高温工况中,主要原因是常规手动平板闸阀中的非金属密封件在390℃温度下密封材料已融化失去密封作用。
发明内容
本发明的目的在于:设计一种金属密封热采手动平板闸阀,既具有普通闸阀的通用性能,也能使用在390℃超高温状态下,具有密封可靠、维修方便等特点。
本发明的技术解决方案是:该热采手动平板闸阀包括阀体、阀板、阀座、C形金属密封圈、阀盖、阀杆、阀杆密封填料、支撑座、填料压盖、压板、螺栓、轴承座、轴承和阀杆转换接头,阀座安装在阀体的内腔中,阀座的中间安装阀板,阀座的凹槽中安装C形金属密封圈,阀杆的底端拧入阀板中约3~5牙,阀体上安装阀盖,阀杆从阀盖的底部穿出,阀杆密封填料通过阀杆安装阀盖内并用填料压盖压实,支撑座从阀杆穿过与阀盖通过螺纹连接在一起并紧固,压板位于填料压盖上通过螺栓安装在支撑座中,轴承座通过螺纹与支撑座连接在一起并用紧定螺钉连接固定,轴承座上安装轴承和阀杆转换接头,阀杆转换接头连接阀杆,整体构成金属密封热采手动平板闸阀。
其中,阀杆密封填料包括铜垫片、密封填料和弹簧,两铜垫片之间安装密封填料,顶端铜垫片的上方安装弹簧,整体构成阀杆密封填料。
本发明具有以下优点:
1、将C形金属密封圈安装到阀座中密封阀座与阀体,C形金属密封圈采用外开口结构,保证阀门处于阀后密封,降低开关扭矩,保证阀门低压密封;
2、 在阀盖上端口安装内置弹簧的阀杆密封填料,支撑座与阀盖通过螺纹连接在一起并通过紧定螺钉固定,防止阀门在开关过程中将支撑座带动旋转;
3、压板位于填料压盖上通过螺栓安装在支撑座中,通过螺母对称压紧压板将填料压盖带动向下运动不断压紧内置弹簧的阀杆密封填料,达到密封阀杆的效果;
4、当阀杆密封填料出现损耗,弹簧提供推力使阀杆密封填料与阀杆间密封,当阀杆出现轻微泄漏时,拧紧螺栓进一步压紧阀杆密封填料。
附图说明
图1为本发明的结构示意图。
