Abstract

一种可换阀座式闸阀,解决了现有技术一旦泄漏则必须将整个闸阀更换掉,费时、费力,浪费原材料,影响生产的不足。其特征是:阀芯3置于可换阀座1内,可换阀座1经螺栓与固定阀座4相连,管道与阀体连接。缩短检修时间,减少整个阀门更换的费用。加工工艺简单,密封性能提高。固定阀座不易损坏,解决了法兰、螺纹连接的加工成本。可供控制管路中的介质用。

Description

可换阀座式闸阀
本实用新型涉及一种阀,特别是一种可换阀座式闸阀。
现有技术中的阐阀,其目的是控制管路中的介质流通。其构造是阀座内设置一阀芯,阀座的两端与管路相连。其不足之处是在使用过程中,因磨损、介质腐蚀、冲刷等使密封面破损而发生泄漏。为了减少泄漏,密封面一般选用耐磨性、热硬性、耐腐蚀好的合金材料,但绝对不损坏的材料是不存在的。所以因密封面损坏而导致闸阀泄漏是不可避免的。而一旦泄漏则必须检修或将整个闸阀更换掉,费时、费力,浪费原材料,影响生产。
本实用新型的目的在于解决现有技术中的不足之处,而提供一种可换阀座式闸阀。
本实用新型的技术解决方案是:在阀体2内螺接一个可换阀座1,阀芯3置于其间。闸阀若发生泄漏,更换阀芯3或可换阀座1即可。而不必更换固定阀座4在内的整个闸阀。其具体构造是阀芯3置于可换阀座1内,可换阀座1经螺栓与固定阀座4相连,阀体2与管道连接。
本实用新型相比现有技术所具有的优点是:
1.缩短检修时间,减少整个阀门更换费用。
2.能更好、合理地采用软密封弹性塑性材料和密面环向波纹,加工工艺简单,密封性能提高。
3.固定阀座不易损坏,减少了介质外泄,节约了法兰、螺纹连接的加工成本。
图1、图2、图3分别是可换阀座的主视图、俯视图和左视图。
图4是本实用新型的整体结构剖视示意图。
本实用新型的最佳实施例与说明书的技术解决方案一节完全相同,故省略。可供控制管路中的介质用。
