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.
我们经常将2英寸视为分界线，以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尺寸。即使对于大尺寸的球阀，我们也会有时使用锻造方式。与铸钢球阀相比，锻造钢球阀可以承受更多的强度和更可用的。原材料锻造的质量具有更好的质量，缺陷较差。对于高压工作状态，我们最好选择锻造钢球阀。铸球阀门的重量较少，成本低于锻造。厦门Dervos是一家API认证的止回阀制造和贸易公司，专门生产各种阀门。除了球阀外，我们还生产其他工业管道阀门，如闸阀，圆形阀门，塞阀和蝶阀。要了解有关我们行业领先产品的更多信息，请立即与我们联系。
作为管道中的部件，阀门控制流体的连接和切断。阀门就像汽车上的刹车片，一个人破裂，可能会导致意外后果。因此，阀门的性能和使用寿命直接影响系统的操作。如果阀门损坏，则系统必须关闭系统进行维护，损耗带来的损耗大致超过了这种阀门的成本。阀门的质量和寿命非常重要。波纹管密封地球阀在两个方面都特别出色。它的双密封保证零泄漏，但在氦质谱测试中也达到零泄漏。非常安全可靠。波纹管可以在没有损坏的情况下循环超过10,000次，大大超过普通全球阀门包装密封的使用寿命。此外，波纹管密封阀可以防止外部灰尘进入阀体以确保介质的清洁度。 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.

The disc of a tilting disc check valve has a pivot point at the center of it. It is desinged to overcome weaknesses of general type swing check valve. Compared to swing type check valve, the tilting check valve could remain fully open and steady at lower flow rates. That is to say, the swing check valve needs a high velocity of fluid to keep disc open and a higher cracking pressure. For low pressure situation, the pressure drop of a tilting disc check valve is much lower than the swing type. But at a higher flow rate, the tilting check valve has higher pressure drop than swing type.
