分类特点
电动球阀的类型包括: 硬密封球阀, 软密封球阀, 浮动球球阀, 固定球阀, 轨道球阀, V型球阀, 三通球阀, 不锈钢球阀, 锻钢球阀, 排灰球阀, 抗硫球阀, 三通球阀, 气动球阀, 电动球阀, 卡套球阀, 焊接球阀, 法兰球阀, 螺纹球阀.

硬密封: 密封材料: 金属对金属密封 (例如不锈钢, 碳化物), 通过精密加工提高表面硬度 (比如喷涂, 铺面) (阀体HRC78, 阀座HRC72). 高温高压: 可承受-196°C至600°C的温度和1.6-150MPa的压力. 适合蒸汽, 热油, 高压气体及其他介质. 腐蚀性介质: 金属密封面耐酸碱腐蚀 (例如化工生产中的高腐蚀性液体). 含有颗粒的介质: 金属硬度高, 耐磨性强, 且不易被颗粒侵蚀损坏 (比如煤炭, 纤维介质). 防火要求: 金属结构在高温下保持稳定，不会因材料软化而造成泄漏. 密封: 金属密封面存在微小间隙, 工业场景下微量泄漏是可以接受的; 高精度硬密封球阀 (例如弹簧预紧结构) 可以将泄漏控制到非常低的水平. 耐磨性: 密封面硬度高 (如阀座HRC72), 长期使用不易磨损，使用寿命长. 操作力: 金属之间的摩擦力很大, 且启闭扭矩高于软密封球阀, 但弹簧预紧设计可以优化操作体验. 成本: 材质及加工精度要求高, 且价格通常高于软密封球阀.

软密封: 密封材料: 非金属材料 (如聚四氟乙烯, 橡皮), 具有弹性，可以补偿加工误差. 结构特点: 以浮球式为主, 球体与阀座通过软质材料的弹性变形实现密封. 密封圈通常设计成可活动的，易于拆卸和更换. 清洁低压介质: 适用于水等清洁液体, 溶剂, 酸, 天然气, ETC。, 压力一般低于6.4MPa. 低温环境: 工作温度范围通常为-40°C至180°C. 超过范围可能会导致密封材料老化或变形. 含有悬浮颗粒: 球在打开和关闭时具有擦拭特性, 可去除附着在密封面上的颗粒, 但长期使用可能会磨损密封面. 密封: 软质材料具有良好的弹性，可以紧紧包裹住球体，从而达到 “零泄漏”. 适用于漏电要求严格的场景 (例如食品和制药行业). 流阻: 全通径设计, 流畅的流动路径, 流阻小, 和低压损失. 操作力: 启闭力矩小, 操作灵活, 并且易于远程控制. 维护: 密封圈属于易损件，需要定期更换, 且长期使用成本可能较高.

浮球: 球阀的球体是浮动的. 在介质压力作用下, 球体能产生一定的位移并紧压在出口端的密封面上，保证出口端的密封. The floating ball valve has a simple structure and good sealing performance, but all the load of the working medium on the ball is transferred to the outlet sealing ring. 所以, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to a higher pressure impact, the ball may deflect. This structure is generally used for medium and low pressure ball valves.

固定球: The ball of the ball valve is fixed and does not move when pressed. Fixed ball and ball valves all have floating valve seats. After being subjected to medium pressure, the valve seat moves, causing the sealing ring to press tightly on the ball to ensure sealing. 轴承通常安装在滚珠的上下轴上, with small operating torque, and are suitable for high-pressure and large-diameter valves. In order to reduce the operating torque of the ball valve and increase the reliability of the seal, lubricating oil is used to form an oil film, which enhances the sealing and reduces the operating torque. It is more suitable for high-pressure and large-diameter ball valves.

Elastic ball: The ball of the ball valve is elastic. The ball and valve seat sealing ring are both made of metal materials, and the sealing specific pressure is very large. The pressure of the medium itself cannot meet the sealing requirements, and external force must be applied. This kind of valve is suitable for high temperature and high pressure media. The elastic sphere obtains elasticity by opening an elastic groove at the lower end of the inner wall of the sphere. When closing the channel, use the wedge-shaped head of the valve stem to expand the ball and compress the valve seat to achieve a seal. Loosen the wedge-shaped head before turning the ball, and the ball will return to its original shape, leaving a small gap between the ball and the valve seat, which can reduce friction on the sealing surface and operating torque.

Q941F、Q941Y型PN16~PN63电动球阀

Electric ball valves are typically used in applications requiring strict sealing. 除了控制气体, 液体, 和蒸汽介质, 它们还适用于控制污水和含有纤维杂质的介质. They are widely used in industries such as petroleum, 化学, 冶金, 轻工业, 造纸, 发电厂, and refrigeration.

Q941F and Q941Y type PN16~PN63 electric ball valves Product Features

(1) 低流体阻力: 球阀在所有阀门类型中具有最低的流体阻力. 即使是缩径球阀也具有非常低的流体阻力.

(2) 推力轴承减少阀杆摩擦扭矩, 确保阀杆长期平衡、灵活操作.

(3) 优良的阀座密封性能: 密封圈, 由PTFE等材料制成, 易于密封, 球阀的密封能力随介质压力的增大而增大.

(4) 可靠的阀杆密封: 因为阀杆只旋转，不上下移动, 阀杆填料密封不易损坏, 密封能力随介质压力的增大而增大.

(5) 由于PTFE等材料具有良好的自润滑性能, 与球的摩擦损失低, 延长球阀的使用寿命.

(6) 底部安装的阀杆和阀杆头上的凸起台阶可防止阀杆弹出. 如果火灾导致阀杆密封损坏, 凸起的台阶仍然可以与阀体形成金属对金属的接触, 确保阀杆密封.
