磅级螺纹球阀产品概述

磅级螺纹球阀是一种按磅级（Class）压力标准设计、采用螺纹连接的球阀，主要用于工业管路系统中控制介质的通断，其压力等级符合美标磅级规范（如Class 150、300、600等），适配相应压力等级的管道系统。

 磅级螺纹球阀- 压力标准：遵循美标磅级压力体系，压力等级通常涵盖Class 150至Class 2500，可满足不同高压工况需求，阀体强度与密封性能随磅级提升而增强，适配对应压力等级的管路设计。

磅级螺纹球阀- 连接方式：采用螺纹连接（常见NPT、BSP等美标或英标螺纹），连接紧密且安装便捷，无需焊接，适合中小口径管道（通常DN15~DN100），便于快速拆卸和维护。

磅级螺纹球阀- 结构特点：阀体多采用锻造或铸造工艺（材质如碳钢、不锈钢、合金钢材），结构紧凑，球体与阀座精密配合，确保高压下的稳定性；阀杆多采用防吹出设计，提升操作安全性。

磅级螺纹球阀- 密封性能：阀座根据工况选用耐温、耐腐材料（如增强聚四氟乙烯、金属密封件等），配合螺纹连接的机械密封，可实现密封，满足中高压下的低泄漏要求。

磅级螺纹球阀- 操作方式：以手动操作为主，手柄旋转90°即可完成全开或全关，操作轻便；部分型号可配备蜗轮、气动或电动驱动装置，适应自动化控制场景。

磅级螺纹球阀- 适用范围：工作温度根据材质和密封件不同可达-29~425℃，适用于水、蒸汽、油品、天然气、腐蚀性介质等，广泛应用于石油化工、天然气、电力、制药等工业领域，尤其适配美标体系的管路系统。

 The pound-class threaded ball valve is a type of ball valve designed according to the pound-class (Class) pressure standard connected via threads. It is mainly used to control the on-off of media in industrial pipeline systems. Its pressure rating complies with the American standard pound-class specifications (such as Class 150, 300, 600, etc.), adapting to pipeline systems of corresponding pressure levels.

 The pound-class threaded ball valve- Pressure standard: Follows the American standard pound-class pressure system, with pressure ratings usually covering Class 150 to Class 2500, which can meet the needs of different high-pressure working conditions. The valve body strength sealing performance increase with the pound-class, adapting to the pipeline design of corresponding pressure levels.

The pound-class threaded ball valve- Connection method: Adopts threaded connection (common American British standard threads such as NPT, BSP, etc.), with tight connection convenient installation. No welding is required, making it suitable for small medium-diameter pipelines (usually DN15~DN100) facilitating quick disassembly maintenance.

The pound-class threaded ball valve- Structural features: The valve body is mostly manufactured by forging casting processes (materials such as carbon steel, stainless steel, alloy steel), with a compact structure. The ball valve seat are precisely matched to ensure stability under high pressure; the valve stem mostly adopts a blow-out proof design to enhance operational safety.

The pound-class threaded ball valve- Sealing performance: The valve seat is made of temperature-resistant corrosion-resistant materials (such as reinforced PSeE, metal seals, etc.) according to working conditions. Combined with the mechanical seal of threaded connection, it can achieve reliable sealing, meeting the low leakage requirements under medium high pressure.

The pound-class threaded ball valve- Operation mode: Mainly manually operated, with a 90° rotation of the handle to complete full opening closing, featuring easy operation; some models can be equipped with worm gear, pneumatic electric drive devices to adapt to automated control scenarios.

The pound-class threaded ball valve- Application range: The working temperature can reach -29~425℃ depending on materials seals, suitable for water, steam, oil products, natural gas, corrosive media, etc. It is widely used in industrial fields such as petrochemical, natural gas, electric power, pharmaceuticals, especially suitable for pipeline systems of the American standard system.
