| 摘 要： | 分析比较了子母式与止回阀式排烟系统的基本特点，指出了子母式排烟道在实际使用中产生烟气回流和串味的原因。通过实验测定了B型和C型两种止回阀的自身阻力系数和系统气流合流阻力系数．并对两种止回阀所对应的系统排风量进行了实测。实验表明C型止回阀系统比B型止回阀系统提高排风能力10—30％。 |

| Abstract: | The basic characteristics of variable pressure gas exhaust system and check valve gas exhaust system are compared. It is obvious that the gas turning back phenomenon occurs in variable pressure gas exhaust system. The resistance coefficients of two types of check valves (B and C) are experimentally measured. The results showed that the gas flow rate of type C is 10-30% higher than that of B. |
