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.

答案绝对是一个否！在结构中，如果空间是有限的闸阀依赖于中压以紧密密封表面，从而达到无泄漏的效果。打开和关闭时，盘和座椅密封表面始终接触并彼此摩擦，这导致磨损的密封表面。当闸阀即将关闭时，管道的前后和后部之间的压力差非常大，这也有助于更严重的密封面损坏。闸阀的结构比球阀的结构更复杂。就形状栅极阀门的形状较高而比全球阀更窄，假设它们具有相同的口径。此外，闸阀的阀门落入两类，上升或不上升，而全球阀门的阀门则没有。工作原理阀门阀门打开并靠近阀杆，这意味着当手轮转动时，手轮向上和向下移动杆。至于门阀，转动手轮，阀杆上下移动，但手轮本身保持在相同的位置。他们的流速随着而变化。 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.
