在乙烯热解过程中，传递管线阀门和除焦阀(简称TLV和DV)是必不可少的，其性能对过程的运行和安全有着显著的影响。首先,我们来传输管阀(电磁阀)&除焦阀(DV)特点:DN不同于3 - 54英寸,我们传输管阀&除焦阀可以使用几乎所有类型的乙烯裂解炉,包括CBL (SEI), BYC (Wison)、SRT(鲁玛斯),南加州大学(S&W) Pyrocrack(林德)SC-II (KRB)在市场上和其他受欢迎的类型。转换管线阀门和除垢阀工作在非常苛刻的应用环境中，处理高温、污垢条件、高密封性要求、高可靠性要求，从安全角度来看，它们是至关重要的。因此，我们关心产品的设计和选择。主要关注以下性能:首先，我们关注的是抗结焦性能，特别是在开启位置和开关过程中;其次是颗粒阻力，主要是指密封面不被颗粒覆盖。减少压力损失，以免导致密封失效或妨碍操作;最后，我们特别注意阀门的可持续服务和易于维护。十多年来，我们一直是阀门行业的佼佼者。我们位于中国，在生产阀门的同时，我们与一大批优秀的阀门供应商合作，以满足您的各种需求。 If you have any needs of or interests in these two kinds of special valves, welcome to contact us for more product information. Or if there is anything we can help with, we shall be more than pleased to do so.
时间过得多快!Dervos经历了另一个充满挑战但收获颇丰的一年，并准备步入其在阀门市场的第13个年头。是时候庆祝它的生日了。和往常一样，我们抽出一天时间来参加德沃斯的大型活动。这一天，我们称之为快乐的一天，是由相当多的活动。我们租了一个大房子，里面有各种各样的娱乐设施，比如卡拉ok，私人电影院，AR游戏等等。宽敞的厨房和用餐区更有利于我们的第一项活动——集体烹饪!最棘手的部分是——你知道，参与者是一群城市白领，他们靠所有的外卖应用程序吃饭，你对他们还有什么期望?——结果证明，这不仅仅是令人惊讶的:热辣椒油鱼片、肉丸、蘑菇炖菜和令人印象深刻的海鲜锅，由Dervos的创始人埃里克提供。说到创始人，另一个肯带来了一个精致的13形蛋糕，既漂亮又可口。再加上精美的甜点，那天中午的晚餐真的为快乐的一天画上了一个美好的开端。 Then we move to the recreational area. If you see someone screaming BACK OFF! STAY AWAY FROM ME! wielding gamepad, shooting monsters on screen, don’t worry, that’s just Jona playing AR games. She’s probably going to win the most dedicated player prize if there were any. One more game I’d like to note is ring toss. The ring needs to circle the bottle and win you the gift coupon beneath it. I know it’s kinda old-stuff, but when you attend another game to win extra chances for ring toss if you don’t gain anything at first round, it would be more fun. The gamer needs to spin 5 circles and flip a bottle cap about 2 meters away at once, with one eye covered all the time. It was crazy dizzy, difficult and fun, cause you could never hit it accurately after 5 circles as you thought the cap was there but it was actually not. In the evening, after a string of group games like Guess the song name and Charade, the climax of the day came as the projection screen started playing a surprising video for West, also the game host, whose journey with Dervos has rang the 10-year bell and hasn’t anticipated for this part. After the video, Eric and Ken, on behalf of the big family, awarded him a secret anniversary gift. Now, let’s call it a day, or it would be better to be ‘let call it 13 years’. If Dervos were a 13-year-old boy, it is when the boy explores the world curiously and energetically. It is like a rising sun from the skyline, we’ll see his sun ray, glory and feel his warmth. Dervosers are striving for this day.
我们经常把2英寸作为阀门锻造或铸造的分界线。与其他阀门不同，球阀的制造方法不受阀门通径的限制。即使是大口径球阀，有时也会采用锻造方式。与铸钢球阀相比，锻钢球阀能承受更大的强度，更耐用。原材料锻件质量好，缺陷少。对于高压工况，我们最好选用锻钢球阀。铸造球阀比锻造球阀重量更轻，成本更低。厦门德沃斯止回阀有限公司是一家通过API认证的止回阀生产贸易公司，专业生产各类止回阀。除球阀外，我们还生产其他工业管道阀门，如闸阀、截止阀、旋塞阀、蝶阀等。想了解更多关于我们行业领先的产品，今天就联系我们。

The ball part of floating ball valve is movable. Under the pressure of medium, the ball has a certain displacement and presses on the sealing surface of outlet end to ensure its tight sealing. The floating structure is suitable for ball valve with small size and low & medium pressure rating. The ball part of trunnion mounted ball valve is fixed. Under the medium pressure, the floating seat will move towards the ball to ensure the sealing. The trunnion mounted ball valve is often with larger size and higher pressure.
