一、环形阀的设计计算由于环形阀(图1)不象平板阀和锥形阀那样有明确的d_k、d_f,因此直接采用(1)(2)(3)或(17)式比较困难。为此,必须找到适当的当量值代入,而这些当量值的提出又必须与提供的ξ_k 或ξ_l换算关系协调一致。本文将根据文献[7]关于克劳斯(Kra-uss)和别尔格(Berg)对环形阀A_k、A_x的计算方法的说明以及对系数ξ_k的整理方法来解决环形阀的当量值换算问题。文献[7]提 First, the design and calculation of the ring valve Because the ring valve (Figure 1) does not have a clear d_k, d_f as flat valve and cone valve, so the direct use of (1) (2) (3) or (17) is more difficult. To do this, we must find the appropriate equivalence value substitution, and these equivalence values ​​must be provided in accordance with the ξ_k or ξ_l conversion. This paper will solve the equivalence value conversion problem of the annular valve according to [7] on Krauss and Berg’s description of the method of calculating the annular valves A_k and A_x and the method of adjusting the coefficient ξ_k .
