二、进口真空安全阀用途：

1、用于负压系统：当负压容器系统内负压超过允许值时，该阀自动开启，吸入空气。当负压降低到规定值时，阀门自动关闭，从而保证设备容器及系统的安全运行；

2、用于正常非负压系统：各种腐蚀性介质容器，如吸收塔、蒸馏塔、贮槽、罐等，当通入蒸汽清洗后，如放散阀未打开，蒸汽冷凝，产生负压，安装设备即确保设备设备安全。

二、 Purpose of imported vacuum safety valve:
1. Used for negative pressure system: when the negative pressure in the negative pressure container system exceeds the allowable value, the valve will automatically open to inhale air. When the negative pressure is reduced to the specified value, the valve will automatically close to ensure the safe operation of the equipment container and system;
2. For normal non negative pressure system: all kinds of corrosive medium containers, such as absorption tower, distillation tower, storage tank, tank, etc., when the steam is introduced for cleaning, if the vent valve is not opened, the steam condenses and produces negative pressure, the installation of the equipment ensures the safety of the equipment.
 

三、进口真空安全阀描述：

德国《DE LOCKE》洛克进口真空安全阀适用于温度≤200℃的负压系统，当容器内负压超过允许值时，该阀自动开启，吸入空气；当容器内负压达到允许值时，该阀自动关闭，从而保护设备及系统。安装在正常非负压系统，当容器和系统的放散阀未打开，产生负压时，此阀自动开启。 负压安全阀适用于PN1.0～2.5MPa，工作温度≤200℃的各种容器及设备上，开启压力为-0.001～-0.09MPa。 选用不同的材质,可分别适用于空气、蒸汽、油品、硝酸、醋酸、氧化性介质、尿素等多种介质。

三、 Description of imported vacuum safety valve:
The vacuum safety valve imported from Germany "de lock" is suitable for the negative pressure system with temperature ≤ 200 ℃. When the negative pressure in the container exceeds the allowable value, the valve will open automatically to inhale air; when the negative pressure in the container reaches the allowable value, the valve will close automatically to protect the equipment and system. It is installed in normal non negative pressure system. When the vent valve of the container and system is not opened and negative pressure is generated, the valve will open automatically. The negative pressure safety valve is applicable to all kinds of vessels and equipment with PN1.0 ~ 2.5MPa and working temperature ≤ 200 ℃, and the opening pressure is -0.001 ~ -0.09mpa. Different materials can be used for air, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
