Valve products are widely used, and the performance requirements of valves in different environmental occasions are also different. Here, our Hunan valve manufacturer will introduce a new type - low temperature valve. The working medium of low-temperature valve is mainly flammable and explosive substances, and the low temperature can reach - 269 ℃. Therefore, the following requirements are generally met in the design:

1)支持长时间低温工作

1) Support long-time low-temperature operation

阀门及其组合件在低温介质及周围环境温度下应具有长时间工作的能力(一般为10年或是3500~5000次循环);

The valve and its assembly shall be capable of working for a long time under low temperature medium and ambient temperature (generally 10 years or 3500 ~ 5000 cycles);

2)避免成为热源

2) Avoid becoming a heat source

阀门相对于低温介质，不应成为一个显着热源，这是因为热量的流入会降低热效率，而且热量流入过多，还可能使阀门内部的低温介质汽化，产生异常升压，造成危险;

Compared with the low-temperature medium, the valve should not become a significant heat source, because the inflow of heat will reduce the thermal efficiency, and too much heat inflow may also vaporize the low-temperature medium inside the valve, resulting in abnormal pressure rise and danger;

3)手轮手轮不受低温影响

3) The handwheel is not affected by low temperature

低温介质不应对手轮的操作性能和填料的密封性能产生有害影响;

Low temperature medium shall not adversely affect the operating performance of handwheel and the sealing performance of packing;

4)防爆防火

4) Explosion proof and fire prevention

直接和低温介质接触的阀门组合件的结构应当符合相关的防爆和防火要求;

The structure of valve assemblies in direct contact with low-temperature medium shall meet relevant explosion-proof and fire-proof requirements;

5)预防摩擦部件擦伤

5) Prevent chafing parts

在低温状态下工作的阀门组合件不能润滑，所以需要采取措施，防止摩擦部件被擦伤。

The valve assembly working at low temperature cannot be lubricated, so measures need to be taken to prevent the friction parts from being scratched.
