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.

答案绝对是否定的!在结构上，如果空间有限，闸阀依靠介质压力将其表面紧密密封，从而达到无泄漏的效果。启闭时，阀瓣与阀座密封面总是相互接触和摩擦，导致密封面磨损。当闸阀即将关闭时，管路前后压差很大，这也使得密封面损坏更加严重。闸阀的结构比截止阀复杂。在口径相同的情况下，闸阀的形状要比截止阀高、窄。另外，闸阀的阀杆分为上升和不上升两种，截止阀的阀杆不分为上升和不上升两种。工作原理截止阀开启和关闭时阀杆是上升的，这意味着当手轮转动时，手轮随着阀杆上下移动。对于闸阀，手轮转动，阀杆上下移动，但手轮本身保持在同一位置。它们的流量是不同的。 Gate valves have to be full opened or closed, while globe valves do not. Globe valves have a defined inlet and outlet direction, while gate valves do not. In addition, the gate valve has only two states: fully open or fully closed,and the long travel of the disc results in a longer switching time.The time a globe vale needs is muchshorter. Most importantly, thedisc of the globe valve can stop at a certain place inthe valve body to do flow regulation. The gate valve can only be used for cut-off and has nosuch function. Performance differences Globe valves can be used for both cut-off and flow regulation. The fluid resistance of globe valve is relatively high, and it takes more effort to open and close, but because the distance between the valve plate and the sealing surface is short, the opening and closing stroke is short. When gate valve is fully open, the medium flow resistance in the valve body channel is almost 0, so the gate valve opening and closingwon’t be very laborious. But the gate plate is far from the sealing surface, opening and closing time is longer.
