时光飞逝！Dervos有另一个具有挑战性的，富有成效的一年，并准备进入阀门市场的第13届。是时候庆祝它的生日了。像往常一样，我们为这场大型Dervos留下了一天。这一天，我们称之为快乐的日子，由相当多的活动组成。我们租了一个大房子，有一个散毛的杂项娱乐设施，例如卡拉OK，私人电影，ar比赛等。更重要的是，宽敞的厨房和用餐区也有利于我们的第一项活动 - 集团烹饪！假设痒痒部分 - 您知道，参与者是一群由所有食品交付应用程序喂养的城市白领工人，您对他们的期望多大？ - 原来不仅仅是惊人：鱼叉在辣椒，肉丸，蘑菇炖锅和埃里克，埃里克，埃里克，埃里克，埃里克，埃里克，埃里克州埃里克州埃里克，创始人。谈到创始人，另一个肯带来了一块精致的蛋糕，成形为13号，美丽和卑鄙。 Plus the exquisite dessert, the meal of that noon really set a wonderful beginning of the happy day. 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.
我们通常以2英寸为分界线来决定阀门的锻造或铸造。与其他阀门不同，球阀的制造方法不受阀门尺寸的限制。即使是大尺寸的球阀，我们有时也会采用锻造的方式。与铸钢球阀相比，锻钢球阀具有更高的强度和使用寿命。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轻，成本低。厦门德孚是一家通过API认证的止回阀生产贸易公司，专业生产各类阀门。除球阀外，我们还生产其他工业管道阀门，如闸阀、截止阀、旋塞阀和蝶阀。欲了解更多有关我们行业领先产品的信息，请立即联系我们。
阀门作为管道中的一个部件，控制着流体的连接和切断。气门就像汽车上的刹车片，一坏，就可能导致意想不到的后果。因此，阀门的性能和使用寿命直接影响系统的运行。如果阀门损坏，必须关闭系统进行维护，由此带来的损失大大超过了这几个阀门的成本。阀门的质量和寿命非常重要。波纹管密封截止阀在这两方面尤为突出。它的双重密封保证了零泄漏，但在氦质谱测试中也达到了零泄漏。非常安全可靠。波纹管可循环10000次以上而不损坏，大大超过了普通截止阀填料密封的使用寿命。另外，波纹管密封阀可以防止外部灰尘进入阀体，保证介质的清洁度。在高纯硅粉、纯氧、食品、真空等工况下，波纹管截止阀仍具有非常优异的性能。普通截止阀在切换过程中，填料与阀杆之间会产生动摩擦，导致填料磨损失效。截止阀在高低温场合，其填料会膨胀或收缩，填料发生变化，导致填料密封失效；在低温条件下，填料容易结冰，在切换过程中容易被冰划伤。总之，波纹管截止阀与普通截止阀相比的优点可以概括如下。1.波纹管截止阀能满足氦质谱仪零外漏的要求。2.波纹管密封截止阀的使用寿命远高于普通截止阀，其填料易受影响，更换频率较高。3.波纹管密封截止阀在阀杆密封处有一个金属屏障，可用于阀门内外需要绝对隔离的工况。4.波纹管密封截止阀的波纹管可以伸缩，不受热膨胀和热收缩的影响，在温差大的场合具有非常明显的优势。5.波纹管阀具有双重密封。波纹管的设计，使填料与介质完全隔离，很好地保护了填料，大大延长了使用寿命。德沃斯是一家领先的阀门制造商和为不同行业提供工程产品的供应商。如果您正在寻找可行的解决方案，请查看我们种类繁多的高质量阀门，包括闸阀、球阀、蝶阀以及其他控制阀等。有关我们高质量产品的更多信息，请立即与我们联系。

闸阀和地球阀之间有什么区别？
门阀和灯罩是我们所知道的两个最常见的阀门。它们的差异是：
1.gate阀仅用于开关功能。但是全球阀可用于同时关闭和节流。
2.截止阀的流阻大于闸阀。同样，截止阀比闸阀有更多的压降。
从开口高度的角度来看，门阀需要比地球阀更大的安装空间。
4.闸阀密封面磨损比截止阀大。
5.全球阀的扭矩值大于闸阀。
