电磁阀的增加的增加意味着它的上升未来。今天，我们将讨论为什么它变得越来越受欢迎。首先，介绍了适用于产业的环境保护和可持续发展政策引发了节能概念，这符合水，能源和材料等电磁阀节能资源的开发标准。其次，电磁阀设计成消耗较少的能量并降低由于流动阻力引起的能量损失。这是阀门行业的发展方向。因此，电气设备广泛用于节能行业。您可以通过升级其结构并选择低功耗和低噪声设备来使用少消耗能量。在上述两个原因的前提下，我们应该在电磁阀的研究，创新和开发中投入更多的能量和资金，并使其在高新技术产业中发挥着重要作用。

铸造方法广泛用于阀门行业。在本文中，我们将讨论铸钢阀的优点和缺点。优异1.铸钢阀由液态金属制成，因此尺寸和形状更加柔韧，即使是复杂的形状。2.材料和化学成分方面具有各种各样。因此，合金钢阀通常由铸造方法制成。3.不太复杂，昂贵的过程导致其广泛的可用性。4.铸钢阀具有圆形边缘的轮廓形状。即使在小型空间和管道中，这使它们易于安装。Demerit 1.熔化时有些材料丢失。然后将液体重新加工，因为它被放入并从模具中取出。 The overall process will generate lots of material waste. 2. There can be some impurities like cracks and voids during its solidifying process. This will lead to a lower mechanical property. 3. The heat treatments can alter the micro-structure of the castings after welding. This results in higher creep and lower hardness of the valve. Rigorous inspection is required to make sure the valve has retained its strength and creep resistance after being welded.

插头阀是相对较旧的阀门，包括套管插头阀，润滑塞阀和多路塞阀。它依赖于插头体围绕阀体的中心线旋转，以达到打开和关闭的目的。插头阀的功能通常用于切断，分配和改变介质流动方向。插头阀具有简单的结构;外部尺寸很小;操作期间只需要90％的流体阻力。它被广泛使用，尤其是低压，小直径和中温。插头阀的缺点是开关是费力的，密封表面易于磨损，并且易于在高温和压力下卡住，这不适合调节流量。球阀从插头阀进化。它的开启和关闭构件是球。 The ball is rotated 90 degrees around the axis of the valve stem to achieve the purpose of opening and closing. It is mainly used to cut, distribute and change the flow of the medium Orientation, the ball valve designed as a V-shaped opening also has a good flow adjustment function. When used for shut-off, the plug valve has a slightly better adjustment capacity than the ball valve, but has limited advantages. Although the plug valve has a sealing surface much larger than the ball valve, the sealing effect is good, but it also brings the disadvantage of too much torque and insufficient flexibility. Due to the influence of the weight of the cock, the conventional positive cock structure is difficult to achieve a large caliber. If you want to use a large-size valve, you must use an inverted cock structure, that is, the cock has its head pointing down. This inevitably reduces the sealing effect under the action of gravity. It has to be sealed by grease injection. It is used for storage and transportation of natural gas and oil, but cannot be used in other industries, because grease will contaminate the medium. Although the ball valve's sealing effect is slightly poor in theory, it can be made into a large caliber. With the improvement of processing accuracy and sealing material, the ball valve's sealing effect can already meet the actual application requirements, and the application range is wider. When used for adjustment, there is not much difference between the two, and appropriate holes can be made in the rotating body for adjustment. Therefore, the general plug valve is used in occasions with higher sealing requirements, but the diameter is generally smaller, and the ball valve can be applied to more and more extensive industrial occasions.

球阀是一种阀门，使用具有圆形通道作为开口和关闭部件的球，并且球用阀杆旋转以实现开启和关闭动作。我们提供各种耳芯安装的球阀，浮动球阀，全焊接球阀等多路球阀。球阀从塞阀展开。它们具有相同的90度旋转动作，差异是球阀具有带圆端口的球，而塞阀具有圆柱形或圆锥形的塞子。在圆柱形塞中，通道通常是矩形的;在锥形插头中，通道是梯形。球阀的主要特点是其结构紧凑，易于操作和维护，不仅适用于诸如水，溶剂，酸和天然气等一般工作介质，还适用于具有苛刻的工作条件的介质，如氧气，过氧化氢等介质，甲烷和乙烯。此外，可以集成或组合球阀体。一般来说，球阀最适合直接打开和关闭，但最近，球阀已经开发并设计用于节流和控制流动。滚珠阀是DVSVALVE.COM的最多阀门之一。
