手动低温高压球阀产品概述

手动低温高压球阀是一种结合了手动操作方式与低温高压工况适应能力的特殊球阀，通过人工旋转手柄驱动球体旋转，实现对低温、高压环境下流体介质的通断控制，广泛应用于对操作灵活性有一定要求且无需自动化控制的场景。以下是其具体介绍：

手动低温高压球阀结构特点：阀体采用耐低温高压的特殊材料（如低温合金钢材）制造，能抵御极端温度下的材料脆化和高压冲击。密封结构经过特殊设计，多采用耐低温密封件（如增强聚四氟乙烯等），确保在低温高压下仍能保持良好的密封性，减少泄漏风险。手动操作部分（如手柄、手轮）设计符合人体工学，便于省力操作，且与阀体的连接牢固，能承受频繁操作。

手动低温高压球阀性能优势：具备耐低温性能（可适应-196℃及更低温度）和高压承载能力（通常可承受几十至几百MPa压力），在极端工况下机械性能稳定。手动驱动方式结构简单，故障率低，维护便捷，无需额外动力源，适用于偏远或无动力供应的场合。密封稳定，操作响应迅速，能精准控制流体通断。

手动低温高压球阀适用范围：常用于天然气液化（LNG）、低温制冷、石油化工、航空航天等领域的低温高压管路系统，可输送液氮、液氧、液化天然气等低温介质，以及高压状态下的其他流体。

手动低温高压球阀连接方式：主要有法兰连接、焊接连接等，可根据管路设计和安装需求选择。

 Product Overview of Manual Cryogenic High-Pressure Ball Valve

The manual cryogenic high-pressure ball valve is a special ball valve that combines manual operation with adaptability to cryogenic high-pressure working conditions. It drives the ball to rotate by manually rotating the handle, realizing the on-off control of fluid media in cryogenic high-pressure environments. It is widely used in scenarios certain operational flexibility is required no automatic control is needed. The specific introduction is as follows:

 Structural features: The valve body is made of special materials resistant to cryogenic temperatures high pressures (such as cryogenic alloy steel), which can resist material embrittlement high-pressure impact under extreme temperatures. The sealing structure is specially designed, mostly using cryogenic-resistant seals (such as reinforced PTFE, etc.) to ensure good sealing performance under cryogenic high-pressure conditions reduce the risk of leakage. The manual operation parts (such as handles, handwheels) are ergonomically designed for labor-saving operation, their connection with the valve body is firm, able to withstand frequent operations.

Product Overview of Manual Cryogenic High-Pressure Ball - Performance advantages: It has excellent cryogenic resistance (adaptable to -196℃ lower temperatures) high-pressure bearing capacity (usually able to withstand tens to hundreds of MPa pressure), with stable mechanical properties under extreme working conditions. The manual drive mode has a simple structure, low failure rate, convenient maintenance. It does require an additional power source, making it suitable for remote areas occasions without power supply. It features reliable sealing rapid operation response, enabling precise control of fluid on-off.

Scope of application: It is often used in cryogenic high-pressure pipeline systems in fields such as liquefied natural gas (LNG), cryogenic refrigeration, petrochemical industry, aerospace, etc. It can transport cryogenic media such as liquid nitrogen, liquid oxygen, liquefied natural gas, as well as other fluids under high-pressure conditions.

Connection modes: Mainly including flange connection welded connection, which can be selected according to pipeline design installation requirements.
