LAV-250-PAA真空阀产品说明
LAV-250-PAA是一款气动控制型真空阀，核心定位为工业管道系统中的真空状态调控与安全防护组件，具备气动与手动双重操作模式，可精准实现真空环境下的管路通断控制，同时集成应急安全切断功能，广泛适配各类需要真空调控的工业生产场景。以下为其核心信息梳理：
一、核心技术特性
- 双模式操作设计：支持气动自动控制与手动应急操作。气动模式下，气缸充入指定压力时活塞上升带动阀杆开启阀门，释放气缸气体后，活塞在弹簧作用下带动阀杆与阀瓣下行实现关闭；手动模式可通过旋转顶部手轮直接开启阀门，提升操作灵活性与应急保障能力；
- 应急安全防护：配备易熔塞安全装置，当阀门周围环境温度达到75℃±5℃（适配低温槽车、储罐等场景的安全标准）时，易熔塞内金属熔化，气缸压力自然排放，阀门自动关闭，有效防范高温风险；
- 可靠密封与适配性：采用密封件压紧阀座的密封结构，真空密封性能优异，可有效维持管路真空度；推测公称通径适配250mm规格，能满足中大型管路的真空调控需求；
- 工业级稳定设计：采用耐磨损、耐腐蚀的工业级元器件，适配工业复杂工况；结构紧凑，安装维护便捷，可适配不同安装姿态的管路布局需求。
二、核心应用领域
- 低温储能与运输：适用于低温槽车、低温储罐式集装箱的管路系统，作为真空状态调控与紧急切断组件，保障低温介质（如液氮、液氧等）存储与运输过程的安全稳定；
- 真空镀膜行业：适配真空镀膜设备的管路系统，精准控制镀膜腔室的真空通断与压力调控，保障镀膜工艺的稳定性与产品质量；
- 食品医药加工：用于食品冷冻干燥、医药真空蒸馏等工艺的管路真空控制，符合工业卫生标准，可避免管路污染影响产品纯度；
- 化工与能源领域：适配化工真空反应釜、能源设备辅助真空系统，实现管路真空状态的精准调控与安全防护，应对复杂化工工况需求。

LAV-250-PAA Vacuum Valve Product Description
LAV-250-PAA is a pneumatic controlled vacuum valve, positioned as a vacuum state control and safety protection component in industrial pipeline systems. It has dual operation modes of pneumatic and manual, which can accurately control the on/off of pipelines in vacuum environments. At the same time, it integrates emergency safety cut-off function and is widely applicable to various industrial production scenarios that require vacuum control. The following is a summary of its core information:
1、 Core technical characteristics
-Dual mode operation design: supports pneumatic automatic control and manual emergency operation. In pneumatic mode, when the cylinder is filled with a specified pressure, the piston rises to drive the valve stem to open the valve. After releasing the cylinder gas, the piston, under the action of the spring, drives the valve stem and valve disc downward to achieve closure; Manual mode can directly open the valve by rotating the top handwheel, improving operational flexibility and emergency support capabilities;
-Emergency safety protection: Equipped with a fusible plug safety device, when the ambient temperature around the valve reaches 75 ℃± 5 ℃ (suitable for safety standards in low-temperature tank trucks, storage tanks, and other scenarios), the metal in the fusible plug melts, the cylinder pressure is naturally discharged, and the valve automatically closes, effectively preventing high temperature risks;
-Reliable sealing and adaptability: The sealing structure adopts a sealing element to press the valve seat tightly, which has excellent vacuum sealing performance and can effectively maintain the vacuum degree of the pipeline; It is speculated that the nominal diameter is suitable for the 250mm specification and can meet the vacuum control requirements of medium and large pipelines;
-Industrial grade stable design: using wear-resistant and corrosion-resistant industrial grade components, suitable for complex industrial working conditions; Compact structure, easy installation and maintenance, adaptable to pipeline layout requirements of different installation postures.
2、 Core application areas
-Low temperature energy storage and transportation: suitable for pipeline systems of low-temperature tank trucks and low-temperature storage tank containers, serving as vacuum state control and emergency shutdown components to ensure the safety and stability of low-temperature media (such as liquid nitrogen, liquid oxygen, etc.) storage and transportation processes;
-Vacuum coating industry: pipeline system adapted to vacuum coating equipment, precise control of vacuum on/off and pressure regulation of coating chamber, ensuring the stability of coating process and product quality;
-Food and pharmaceutical processing: used for pipeline vacuum control in food freeze-drying, pharmaceutical vacuum distillation and other processes, in accordance with industrial hygiene standards, can avoid pipeline contamination and affect product purity;
-In the field of chemical engineering and energy, it is suitable for chemical vacuum reactors and energy equipment auxiliary vacuum systems to achieve precise control and safety protection of pipeline vacuum status, and to meet the requirements of complex chemical working conditions.
