答案绝对是否定的!在结构上，如果空间有限，闸阀依靠介质压力将其表面紧密密封，从而达到无泄漏的效果。启闭时，阀瓣与阀座密封面总是相互接触和摩擦，导致密封面磨损。当闸阀即将关闭时，管路前后压差很大，这也使得密封面损坏更加严重。闸阀的结构比截止阀复杂。在口径相同的情况下，闸阀的形状要比截止阀高、窄。另外，闸阀的阀杆分为上升和不上升两种，截止阀的阀杆不分为上升和不上升两种。工作原理截止阀开启和关闭时阀杆是上升的，这意味着当手轮转动时，手轮随着阀杆上下移动。对于闸阀，手轮转动，阀杆上下移动，但手轮本身保持在同一位置。它们的流量是不同的。 Gate valves have to be full opened or closed, while globe valves do not. Globe valves have a defined inlet and outlet direction, while gate valves do not. In addition, the gate valve has only two states: fully open or fully closed,and the long travel of the disc results in a longer switching time.The time a globe vale needs is muchshorter. Most importantly, thedisc of the globe valve can stop at a certain place inthe valve body to do flow regulation. The gate valve can only be used for cut-off and has nosuch function. Performance differences Globe valves can be used for both cut-off and flow regulation. The fluid resistance of globe valve is relatively high, and it takes more effort to open and close, but because the distance between the valve plate and the sealing surface is short, the opening and closing stroke is short. When gate valve is fully open, the medium flow resistance in the valve body channel is almost 0, so the gate valve opening and closingwon’t be very laborious. But the gate plate is far from the sealing surface, opening and closing time is longer.

在乙烯热解过程中，传递管线阀门和除焦阀(简称TLV和DV)是必不可少的，其性能对过程的运行和安全有着显著的影响。首先,我们来传输管阀(电磁阀)&除焦阀(DV)特点:DN不同于3 - 54英寸,我们传输管阀&除焦阀可以使用几乎所有类型的乙烯裂解炉,包括CBL (SEI), BYC (Wison)、SRT(鲁玛斯),南加州大学(S&W) Pyrocrack(林德)SC-II (KRB)在市场上和其他受欢迎的类型。转换管线阀门和除垢阀工作在非常苛刻的应用环境中，处理高温、污垢条件、高密封性要求、高可靠性要求，从安全角度来看，它们是至关重要的。因此，我们关心产品的设计和选择。主要关注以下性能:首先，我们关注的是抗结焦性能，特别是在开启位置和开关过程中;其次是颗粒阻力，主要是指密封面不被颗粒覆盖。减少压力损失，以免导致密封失效或妨碍操作;最后，我们特别注意阀门的可持续服务和易于维护。十多年来，我们一直是阀门行业的佼佼者。我们位于中国，在生产阀门的同时，我们与一大批优秀的阀门供应商合作，以满足您的各种需求。 If you have any needs of or interests in these two kinds of special valves, welcome to contact us for more product information. Or if there is anything we can help with, we shall be more than pleased to do so.
时光飞逝！Dervos有另一个挑战性，但丰富了丰富的一年，并准备进入其在阀门市场的第13年。是时候庆祝它的生日了。像往常一样，我们为这个大型Dervos的大型活动们幸免了一天。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！假设的痒痒部分 - 您知道，参与者是一群由所有食品交付应用程序喂养的一群城市白领，您对他们的期望多大？ - 结果不仅仅是惊人：鱼叉在辣椒油，肉丸，蘑菇炖锅和埃里克，Dervos创始人提供的令人印象深刻的海上食物锅。谈到创始人，另一个Ken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.
