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通径的影响。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，锻钢球阀承受强度大，使用性能好。原材锻造质量较好，缺陷较少。对于高压工况，最好选用锻钢球阀。与锻造球阀相比，铸球阀的重量更轻，成本更低。厦门德沃斯是一家通过API认证的止回阀制造和贸易公司，专业生产各种阀门。除了球阀，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的产品，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。阀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，则必须关闭系统进行维护，所带来的损失远远超过这几个阀门的成本。阀门的质量和寿命是如此重要。波纹管密封截止阀在这两方面都特别突出。其双密封不仅保证了零泄漏，而且在氦质谱测试中也达到了零泄漏。非常安全可靠。波纹管可以循环使用10000次以上而不损坏，大大超过普通截止阀填料密封的使用寿命。此外，波纹管密封阀可防止外部灰尘进入阀体，保证介质的洁净度。 In conditions such as high-purity silicon powder, pure oxygen, food, vacuum and other working conditions, the bellows globe valves still have a very outstanding performance. In the process of switching, common globe valves will see dynamic friction between packing and stem, and the packing will be worn and fail. When globe valves are in high and low-temperature occasions, their packing will expand or contract, packing changes, resulting in packing seal failure; As for low-temperature conditions, the packing is easy to freeze, the packing is easy to be scratched by ice in the witching process. In short, the advantages of the bellows globe valve compared with the ordinary globe valve can be summarized as follows. 1. The bellows globe valve can meet the request of zero external leakage in helium mass spectrometry. 2. The service life of the bellows sealed globe valve is much higher than that of the common globe valve, whose packing is susceptible and replacement frequency is higher. 3. The bellows sealed globe valve has a metal barrier at the stem seal, which can be used in working conditions where absolute isolation is required inside and outside the valve. 4. The bellows of the bellows sealed globe valve can expand and contract, which is not affected by thermal expansion and contraction, and it has very obvious advantages in the occasion of large temperature differences. 5. The bellows valve has double sealing. the bellows instinct, the packing is completely isolated from the medium, which protects the packing well and greatly extends the service life. Dervos is a leading valve manufacturer and provider of engineered products for different industries.

特性
暗杆
对于非明杆型阀门，如果阀门开启，阀杆没有向上运动。阀杆通过螺纹进入阀瓣。当阀杆上的手轮旋转时，阀瓣在螺纹上沿着阀杆向上或向下运动，而阀杆保持垂直静止。
实心楔
实心楔板因其简单和强度而成为最常用的圆盘。
具有这种类型的楔形阀的阀门可以安装在每个位置，并且适用于几乎所有液体。固体楔形是单件式实心结构，并且实际上是湍流。
优势
-良好的关闭特性
- 阀门是双向的，因此它们可以在两个方向上使用
通过阀门的压力损失很小
