蝶阀什么时候应该使用变速箱?
蝶阀什么时候应该使用变速箱?
2021-09-10

问:嗨。我在你们的网站上看到了蝶阀。其中一些装有手柄,一些装有变速箱,它们看起来都差不多大小。这两种操作是等价的吗?蝶阀什么时候应该使用变速箱?答:齿轮箱蝶阀和手柄蝶阀都是需要手动操作的蝶阀,所以也可以统称为手动蝶阀。对于小型蝶阀,这两种操作方式可以通用。不同之处在于蝶阀的直径较大。对于口径≤DN200的蝶阀,适用手动操作;DN200范围内的蝶阀也可采用齿轮箱操作。 For butterfly valves of DN200 ormore,Gearbox operation is generally recommended. The reason is that as the calibre of the butterfly valve increases, so does the torque. When the calibre exceeds DN200, it will be very hard to operate with the handle, and the larger the calibre, the harder it will be to operated by a handle. Therefore, if the caliber is DN200 or more, it is better to use a gearbox. When Dervos chellenged to manufacture a butterfly valve of DN3750, we used 4 gearbox to drive the gaint guy.

同心圆蝶阀和对夹蝶阀
同心圆蝶阀和对夹蝶阀
2021-09-02

我相信你们当中学过阀门的人对这些蝶阀的名称并不陌生。但是Dervos发现仍然有很多朋友不能区分同心蝶阀和aWafer蝶阀的区别,有些人甚至认为他们是同一个阀门的不同名称。但它不是。本文将向您介绍同心蝶阀与阿佛尔蝶阀的区别。同心蝶阀因其结构形式而得名。除同心蝶阀外,还有单偏心蝶阀、双偏心蝶阀、三偏心蝶阀几种。它们的名称与蝶板在阀体中的中心位置一致。在结构上,同心圆蝶阀的特点是阀杆轴、蝶板中心和阀体中心在同一位置。同心蝶阀结构简单,通常为软阀座。橡胶或聚四氟乙烯等弹性材料最为常见;同心蝶阀具有很好的密封性能,可实现零泄漏。但受密封材料本身的限制,同心蝶阀只能应用于常温、低压环境。 Its not recommended to use them in high temperature and high pressure. Wafer butterfly valve is named according to the butterfly valve's connection method. In addition toWafer, there are also flange connections,clamp connection,socket-ed,welded and so on. Wafer butterfly valves can be soft-sealed ormetallic-sealed; they can be ofconcentric or eccentric.A concentric butterfly valves may be either clamped or flanged. Aconcentric butterfly valve may be aWafer connection, and aWafer butterfly valve may also be ofconcentric construction. Therefore, the concentric and Wafer are two different butterfly valve classifications, the two are actually not comparable. Choose the correct butterfly valve according to the different working conditions, and that’s all.

蝶阀可以用于热水吗?
蝶阀可以用于热水吗?
2021-08-26

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.
