又到圣诞节了，2021年即将到来。在这两年的交叉点，Dervos当然会举行庆祝活动来纪念这一重要时刻。在圣诞节的早上，我们的秘书为我们每个人准备了一袋糖果。除了糖果，每个人还有一个苹果，这是中国平安夜的一个不同寻常的流行传统。这个传统的产生是因为“苹果”的中文发音与“平安夜”谐音，它代表着美好的祝愿。乒乓球，作为中国最受欢迎的运动项目，在过去的几个月里在德沃掀起了一股热潮。当圣诞节遇到了乒乓球，我们决定举办一个特别的，中国特色的游戏——乒乓球比赛。我们分成4支队伍，经历了一系列的比赛——单打、双打和混合双打，以决定谁能笑到最后。令人惊讶的是，我们真的为开幕式准备了奖杯、剪彩和横幅。太有趣了。 That was a funny and stressful afternoon, you have to say. Because infrequently we took it so seriously that everyone practiced and performed hard, longing for the laurel of the team. Though every team was brilliant no matter the result. And unarguably the best play went to West Lin who led his team to runner-up when the situation was not optimistic for him. In the end of this article, Dervos is honored to spend another year with our customers and friends. We sincerely wish you a happy holiday season and a best new year.
Q: Q41F球阀是什么? Q41F- 16c球阀型号上的字母代表什么意思?德尔沃斯:根据《阀门类型组成方法》，对Q41F-16C球阀进行逐字拆卸分析。——阀门类型:Q为球阀。——驱动方式:可省略手柄操作。——连接方式:4为法兰连接。——结构:1代表浮球直通道——密封面及衬里材料:F代表氟塑料。—公称压力:16代表压力为16kg，即1.6 mpa，或PN16—阀体材料:C为铸钢根据以上资料，我们现在得到的Q41F-16C球阀为16PN手柄式ptfe内衬法兰球阀。如果您想要有配额的Q41F-16球阀或其他类型的阀门，欢迎留言。厦门德孚斯阀门有限公司是一家通过api认证的阀门制造贸易公司，专业生产各类阀门。除闸阀、球阀、截止阀、旋塞阀、蝶阀等各种通用阀门外，我们还可根据客户的要求提供最优质的执行机构。 To learn more about our industry-leading products, contact us today.
随着煤炭工业的快速发展，我国的煤层开采技术已达到先进水平。气动硬密封球阀是煤矿液压系统的重要组成部分之一。当气动硬密封球阀不工作时，德孚列出以下常见故障。故障排除应从以下几个方面着手。1.线圈烧坏气动硬密封球阀的接线可以拆下，用万用表测量。如果有开路，线圈就会烧坏。2.气动硬密封球阀的滑阀套与阀芯间隙的距离很小。它们通常被组装成一个整体。 When there are mechanical impurities or too little oil, it is easy to jam. 3. Air leakage Insufficient pressure caused by air leakage will lead to difficulties in opening and closing the pneumatic hard seal ball valve. This is due to damage of the gasket or wear of the slide valve. Burnt coil, stuck slide sleeve and air leakage are the three common faults of pneumatic hard seal ball valve. Through the above introduction, if you encounter these three situations, you can quickly repair the pneumatic hard seal ball valve. Of course, the best way to prevent these problem is to solve them at the very beginning by find a reliable supplier and quality products. Xiamen Dervos is an API-Certified valve manufacturing and trading company that specializes in the production of various kinds of valve. In addition to all kinds of common valves such as gate valves, ball valves, globe valves, plug valves and butterfly valve, we also offer you the best actuators as long as our customers file their requirements.

Gate valves and globe valves are two of the most common valves we know. The differences beween them are: 1.Gate valve is used only for on-off function. But the globe valve could be used for shutting off and throttling at the same time. 2.The flow resistance of a globe valve is larger than a gate valve. Likewise, globe valves have more pressure drop than gate valves. 3.The gate valve require larger installation space than a globe valve from the perspective of opening height. 4.The gate valve sealing face suffers more abrasion than a globe valve. 5.The torque value of a globe valve is larger than a gate valve. Quality Checking Quality means everything in Dervos. Quality checking team will do inspections according to standard procedure and provide reports. Our QC team will check valve quality from casting and forging, machining, pressure testing, dimension checking, painting & packing.
