一、进口气动高压小型球阀概述

品牌：美国威盾VTON

进口气动高压小型球阀是用于CNG加气站管道系统的球阀，对加压天然气等气体的开关。焊接高压球阀结构简单﹑操作方便﹑流体阻力小﹑密封性能可靠，广泛应用于天然气加气站,液压站化工用高温高压球阀均保证开关万次以上，并可换密封件，增加使寿命减少用户成本。

Pneumatic high-pressure ball valve is the valve piping system for CNG gas station, switch to the pressurized gas. Welding high-pressure ball valve has the advantages of simple structure, convenient operation, small fluid resistance, reliable sealing performance, widely used in natural gas filling stations, hydraulic station with high temperature and high pressure ball valve ensures chemical switch million times, and can change the seal, increased the life reduce the user cost.

二、进口气动高压小型球阀适用场合

1、与可燃气体泄漏监测仪器联接，当仪器检测到可燃气体泄漏时，自动快速关闭主供气阀门，切断燃气的供给，及时制止恶性事故的 发生。

2、与热力设备的极限温度(压力)安全控制器联接，当设备内检测点的温度(压力)超过设定的极限数值时，自动快速关闭供气阀门，停止燃料的供给。

3、与高层建筑的中央消防报警系统联接，当大厦发生火警时，自动切断大厦内的燃气供应，防止煤气爆炸的发生。

4、在城市或工厂的燃气供应管网内设置燃气紧急切断阀，可在中央控制室内集中控制，远程遥控紧急关闭事故现场的管线供气。

加气站紧急切断阀，自锁式天然气紧急切断阀 具有极佳的技术性能，低负荷损失和高可靠性。适用于煤气、天然气及液化石油气等可燃气体，广泛应用于供气管网系统、燃气热能工厂车间、燃气锅炉房及住宅居所的安全设施。

1.Connected to combustible gas leakage monitoring instruments, when the instrument detects a combustible gas leak, it automatically and quickly closes the main gas supply valve, cuts off the supply of gas, and promptly stops the occurrence of malignant accidents.

2.Connected to the limit temperature (pressure) safety controller of the thermal equipment, when the temperature (pressure) at the detection point inside the equipment exceeds the set limit value, the gas supply valve will be automatically and quickly closed to stop fuel supply.

3.Connected to the central fire alarm system of high-rise buildings, when a fire occurs in the building, the gas supply inside the building is automatically cut off to prevent gas explosions.

4.Install gas emergency shut-off valves in the gas supply network of cities or factories, which can be centrally controlled in the central control room and remotely controlled to shut down the gas supply to the accident site.

The emergency shut-off valve of the gas station and the self-locking natural gas emergency shut-off valve have excellent technical performance, low load loss, and high reliability. Suitable for combustible gases such as coal gas, natural gas, and liquefied petroleum gas, widely used in gas supply pipeline systems, gas thermal energy factory workshops, gas boiler rooms, and safety facilities in residential areas.
