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.

一般说明
具有小角度开口的开槽球和V端口球，例如15°球，提供线性固有流动特性。中角V端口阀，如30°球提供修改的相等百分比固有流量特性。自定义端口也可满足特殊控制要求。
好处
流量控制
V-Ball阀的精度提供了通常与标准球阀相关的相等百分比流量特性。
气密截止阀
V滚珠阀具有紧密关闭的能力。因此，在使用过球电压控制阀上的V滚珠阀时，不需要额外的截止阀。
降低压降
与相同的尺寸全球阀相比，V滚珠阀还具有更高的流量系数（CV），其转移流动并使用插头来控制流过阀门的流量。这意味着较小的V球尺寸可用于实现与较大尺寸的全球阀相同的流量。
更高的关闭SFF压力
90°球旋转允许V形球在更高的工作压力下关闭。因此，允许使用更低的扭矩致动器，从而导致最终用户的成本节省和更高的效率。

Usually, we have swing type check valve and lift type check valve. A piston check valve and ball check valve both belong to lift type check valve. In a lot of cases, a piston check valve use spring to retain the disc in closed position. The structure of a piston check valve is very similar to the globe valve just without manual operation. Due to its piston type disc and superior leak tight characteristic, the piston check valves are suitable for small size and high pressure conditions.
