蝶阀可以用于热水吗?

蝶阀可以用于热水吗?在前面的文章中,我们介绍你们认识,蝶阀适用于淡水、污水、海水、海水、蒸汽、天然气、食品、医药、石油和其他管道要求完全密封,零泄漏气体测试,高寿命和工作温度从-10度到150度。蝶阀能否用于热水管道,其实关键在于蝶阀阀体与热水直接接触的阀座密封面材料。我们所说的热水一般是70℃以上的水。如果你在这些温度下使用硬密封蝶阀,就不会有任何问题。但如果是橡胶密封阀座的软密封蝶阀,能否用于热水呢?如果你在网上搜索答案,你会看到很多不推荐在热水中使用软密封蝶阀。原因是软密封蝶阀的橡胶阀座如果长时间暴露在热水中,会老化得更快。会破坏阀门的密封性能,从而缩短阀门的使用寿命。这句话不是问题,橡胶材料的理论温度范围是-20 ~ 150℃,但由于各厂家生产的橡胶质量等级不同,在实际情况下,这个温度范围当然在热水环境下会大大缩小。 However, the soft seal butterfly valve is not completely inadequate for hot water piping. High temperature resistant rubber can be used, which is much more effective and lasts longer. And hard-sealed butterfly valves, ball valves, gate valves and globe valves can also be used instead.
