高温球阀产品概述

高温球阀是一种专为高温环境设计的阀门，主要用于实现管路系统的通断及流量控制。以下是其具体介绍 ：

 高温球阀- 工作原理：通过球体旋转来控制流体通断。当球体的通孔与管道对齐时，阀门开启，介质流过；球体旋转90度，通孔与管道垂直，阀门关闭，阻断介质流通 。

高温球阀- 结构特点：阀体、球体等关键部件通常采用铬钼钢、耐热合金等耐高温材料制造。密封形式多为金属对金属密封，或不锈钢板与石墨复合板密封圈对金属密封。驱动形式多样，有电动、手动、蜗轮杆传动、气动等 。

高温球阀- 产品优势：具有良好的高温适应性，能在极端高温下保持性能稳定。密封稳定，可有效防止介质泄漏。开关操作简便，通过旋转90度即可快速启闭。流通效率高，流阻小。此外，球体和阀座的耐腐蚀性能强，能延长阀门使用寿命 。

高温球阀- 应用领域：广泛应用于石油化工、冶金、电力等行业，可用于控制高温油品、化工原料、燃气、蒸汽等介质的输送 。

 英文概述：High - temperature ball valve is a kind of valve designed specifically for high - temperature environments, mainly used to realize the on - off flow control of pipeline systems. The working principle is to control the on - off of fluid by the rotation of the ball. When the through - hole of the ball is aligned with the pipeline, the valve is opened the medium flows through; when the ball rotates 90 degrees, the through - hole is perpendicular to the pipeline, the valve is closed to block the medium flow. The key components such as the valve body the ball are usually made of high - temperature resistant materials such as chrome - molybdenum steel heat - resistant alloy. The sealing form is mostly metal - to - metal sealing, the sealing of stainless - steel plate graphite composite plate sealing ring to metal. There are various driving forms, including electric, manual, worm - gear drive, pneumatic, etc. It has the advantages of good high - temperature adaptability, reliable sealing, simple operation, high - efficiency flow, strong corrosion resistance, is widely used in petrochemical, metallurgical, electric power other industries.
