Description

一种高温闸阀
技术领域
本发明涉及液体、气体管道流量控制领域，具体地说是一种能够适用高温环境使用的液体、气体的控制阀。
背景技术
目前社会上设计生产的闸阀是一般的锻钢阀门，普遍存在不能适应更高的温度的缺点。
发明内容
本发明为解决普通阀门不耐高温的问题，发明一种带散热片的阀门。
本发明的技术方案是，一种高温闸阀，由阀体、闸板、阀杆、阀盖、手轮构成，其特殊之处是，在阀杆的外围，阀体和阀盖之间加装长颈中法兰，中法兰的外围装有多个散热片，中法兰下端与阀体联结接，上端与阀盖联结，阀盖的上部装有活节螺栓，阀杆的下端装有闸板，阀杆的上端装有阀杆螺母，阀杆螺母的外围装有手轮。
阀门关闭与起开时，转动手轮靠阀杆与螺母的配合，推拉闸板与阀体之间以楔子的作用而达到密封，使闸板沿阀体导轨上升或下降使阀门产生开关。阀体、阀盖、长颈中法兰遇高温时，中法兰外围的散热片向外散发热量。阀盖的松紧可以通过上面的活节螺栓调节。
本发明的技术技术效果是，采用上述的技术方案，可以实现一种在高温环境使用的液体、气体阀门。
附图说明
图1是发明的结构主视图，并作摘要附图。
在图中，1阀体、2闸板、3阀杆、4中法兰、5散热片、6阀盖、7活节螺栓、8阀杆丝母、9手轮。
具体实施方式
下面结合附图实施例，对本发明进一步说明。
如图中所示，在阀杆3的外围，阀体1和阀盖6之间加装长颈中法兰，4，中法兰4的外围装有多个散热片5，中法兰4下端与阀体1联结接，上端与阀盖6由活节螺栓7连接，阀杆3的下端装有闸板2，阀杆3的上端装有阀杆螺母8，阀杆螺母8的外围装有手轮9。
阀门关闭与起开时，转动手轮9靠阀杆3与阀杆螺母8的配合，推拉闸板2与阀体1之间以楔子的作用而达到密封，使闸板2沿阀体1导轨上升或下降使阀门产生开关。阀体1、阀盖6、长颈中法兰4遇高温时，中法兰4外围的散热片5向外散发热量。
