时间过得多快!Dervos经历了又一个富有挑战性但卓有成效的一年，并准备进入其在阀门市场的第13个年头。是时候庆祝它的生日了。像往常一样，我们为德沃斯的大活动留了一天时间。这一天，我们称之为快乐的一天，是由很多活动组成的。我们租了一间大房子，里面有各种各样的娱乐设施，比如卡拉ok，私人影院，AR游戏等等。更重要的是，宽敞的厨房和用餐区也很适合我们的第一个活动——集体烹饪!最棘手的部分是，参与者是一群城市白领，他们吃的是各种送餐应用，你还对他们有什么期望?——结果不仅仅是令人惊叹:辣椒油鱼片、肉丸、蘑菇炖菜，以及Dervos创始人埃里克(Eric)提供的令人印象深刻的海鲜锅。说到创始人，另一个肯带来了一个精致的蛋糕形状成数字13，美丽和美味。再加上精美的甜点，那中午的一餐真的设定了快乐一天的美好开始。 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.

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.

Water hammer is a hydraulic phenomenon that undergoes an abrupt change in its rate of flow and are caused by sudden shutting or slamming. Water hammer will reduce process efficiency, cause valve damage, gasket joint leaks and other problems. The non-slam check valve is designed to reduce water hammer. An internal spring can prevent the disc from slamming close.The design of a non-slam check valve could eliminate pressure flutuations, vibration and damges. Plus, the disc and spring experience minimal wear over time, which will largely extend the service lives of non-slam check compared to swing check valve.
