进口高压球阀(德国进口球阀***)OLES奥莱斯
【进口高压球阀】详细说明：
不锈钢高压球阀的球体是固定的，受压后不产生移动。固定球球阀都带有浮动阀座，受介质压力后，阀座产生移动，使密封圈紧压在球体上，以保证密封。通常在与球体的上、下轴上装有轴承，操作扭距小，适用于高压和大口径的阀门。为了减少气动球阀的操作扭矩和增加密封的可靠程度，出现了油封球阀，既在密封面间压注***的润滑油，以形成一层油膜，即增强了密封性，又减少了操作扭矩，更适用高压大口径的球阀。阀杆防飞结构：阀杆为下装式，防止受压飞出，同时可在火灾后，与阀体形成金属接触，确保阀杆密封。 不锈钢高压球阀的材质是双相不锈钢（Duplex Stainless Steel，简称DSS）是指在其固溶***中铁素体相与奥氏体相约各占50%，一般量少双相钢的含量也需要 达到30%。在含 C 较低的情况下，Cr 含量在18%~28%，Ni 含量在3%~10%。
The ball body of stainless steel high-pressure ball valve is fixed and does not move after being pressed. Fixed ball valves are equipped with floating seats. After medium pressure, the seats move, so that the sealing ring is pressed on the ball to ensure sealing. Usually, bearings are installed on the upper and lower axles of the sphere, and the operation torque is ***all. It is suitable for high pressure and large caliber valves. In order to reduce the operating torque of pneumatic ball valves and increase the reliability of enclosed seals, oil-sealed ball valves h***e emerged, which not only inject special lubricating oil between the sealing surfaces to form a layer of oil film, which enhances the sealing performance, but also reduces the operating torque, and is more suitable for high-pressure and large-caliber ball valves. Stem anti-flying structure: the stem is downloaded to prevent pressure from flying out. At the same time, it can form metal contact with the valve body after fire to ensure the stem seal. The material of stainless steel high pressure ball valve is Duplex Stainless Steel (DSS), which means that the ferrite phase and austenite phase account for 50% respectively in its solid solution structure, and the content of less duplex steel also needs to reach 30%. When the content of C is low, the content of Cr is 18%~28%, and the content of Ni is 3%~10%.
【进口高压球阀】特点：
1、不锈钢高压球阀产品的设计。
3、所有阀门流体阻力***小。
4、开阀速度快吸旋900即可完成开关。
5、阀座材料采用聚醚醚酮PEEK、摩擦系数小密封可靠启闭轻松。
6、球体在阀座之间的运动带有擦拭作用，故可适用带悬浮颗粒的介质。
7、阀杆带有上密封，并采用倒装式结构，可防止在介质压力作用下阀杆冲击。
8、根据用户需要可设有防静电，耐火和防止误操作的锁定机构。
根据开闭力的需要可浮动球或固定球，固定球球阀其阀座地浮动的，依靠介质压力在阀座上产生的活塞效应实现密封，减轻了开闭力。 标准（防火、防静电）
【进口高压球阀】特性：
1、提高前辈的阀座：聚多年球阀制造经验而设计的阀座，确保阀门密封，磨擦系数低，操纵力矩小、多种阀座材料、适应范围广。
2、开关无误的手柄：采用扁头阀杆，与手柄的连接不会错位，从而保证手柄指示的开关状态与阀一致辞。
3、锁紧装置：为防止阀门开关误操纵，在阀门全开、全关位置有锁定孔，确保阀门处于准确的位置。
4、阀杆防飞结构：阀杆为下装式，防止受压飞出，同时可在火灾后，与阀体形成金属接触，确保阀杆密封。
