进口高压小型球阀(德国OLES奥莱斯阀门)
【进口高压小型球阀】详细说明：
进口高压球阀主要零部件经过专业锻制，克服了铸钢阀门潜在的缺陷，在大工作压力下能够保持其结构的抗压均匀性。适用介质： 水、油、气等非腐蚀性介质和酸碱腐蚀性介质。电动高压球阀广泛应用于化工、石油、天然气、冶金、等行业及含硫化氢介质、杂质多、腐蚀严重的天然气长输管线。电动高压球阀主要特点如下：
三分体式连接锻钢固定球阀，是将阀体在两阀座部位沿与阀门通道轴线相垂直的截面分为三部分，整台阀门沿阀杆中心轴左右对称，它在管道上主要用于切断、分配和改变介质流动方向。它的大枢轴结构保证在高压下准确的球体中心位置，保证了阀门良好的操作性能；标准阀座采用弹簧结构，将阀座推向球体，保证了良好的进出口双向密封性能；利用自带的排放阀，阀体中腔可向外排放；枢轴采用防吹出保护结构，有效地防止泄漏；低磨擦系数的轴承，使得扭矩减少到小，便于阀门启闭；阀杆与阀体有效的接触，使防静电接地装置性能优越等。具有性能优异，可靠性高，用途广泛，价格合理等优点。
The main parts of imported high-pressure ball valves are forged by professional manufacturers, which overcomes the potential defects of cast steel valves and maintains the uniformity of pressure resistance under the maximum working pressure. Applicable media: water, oil, gas and other non-corrosive media and acid-base corrosive media. Electric high-pressure ball valves are widely used in chemical industry, petroleum, natural gas, metallurgy, and other industries, as well as in natural gas pipelines with hydrogen sulfide medium, many impurities and serious corrosion. The main characteristics of the electric high pressure ball valve are as follows:
The three-body connection forged steel fixed ball valve divides the cross-section of the valve body at two seats perpendicular to the axis of the valve passage into three parts. The whole valve is symmetrical along the central axis of the valve stem. It is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. Its large pivot structure ensures accurate ball center position under high pressure and good operation performance of the valve; the standard valve seat adopts spring structure to push the valve seat to the ball, which ensures good two-way sealing performance for inlet and outlet; the valve body cavity can be discharged outward by using the self-contained discharge valve; the pivot adopts blowout-proof protection. The structure can effectively prevent leakage; the bearing with low friction coefficient can minimize the torque and facilitate the opening and closing of the valve; the effective contact between the stem and the valve body can make the anti-static grounding device have superior performance. It has the advantages of excellent performance, high reliability, wide use and reasonable price.
【进口高压小型球阀】结构特点：
①流体阻力小，球阀是所有阀类中流体阻力小的一种，即使是缩径球阀，其流体阻力也相当小。
②开关迅速、方便，只要阀杆转动90o，球阀就完成了全开或全关动作，很容易实现快速启闭。
③阀座密封性能好。大多数球阀的密封圈都采用聚四乙烯等弹性材料制造，软密封结构易于保证启封，而且球阀的密封力随着介质压力的增高而增大。
④阀杆密封可靠。球阀启闭时阀杆只作旋转运动而不作升降运动，阀杆的填料密封不易破坏，且阀杆倒密封的密封力随着介质压力的增高而增大。
⑤由于聚四氟乙烯等材料具有良好的自润滑性，与球体的摩擦损小，故球阀的使用寿命长。
⑥可配置气动、电动、液动等多种驱动机构，实现远距离控制和自动化操作。
⑦阀体内通道平整光滑，可以输送粘性流体、浆液以及固体颗粒。
⑧安装简便，能以任意方向安装于管道中的任意部位。
【进口高压小型球阀】工作原理：
当气动执行器与电路和系统气源接通后，空气通过管道A或B管进入A缸(B缸)推动活塞向一端运动，从而带动旋转轴和球芯转动90°；气动执行器顶部连动可视器，当绿色标志指向“开”字时标志阀门开启。回信器信号灯绿灯亮时阀门处在开启位置，而红灯亮时阀门处在关闭位置定位器可调节阀门管道流量
