    • The pressure control valve is structured such that a first port is formed on one side of a casing, a second port is formed on the other side, and, in the casing, there are disposed not only a positive pressure valve which, when the pressure on the first port side becomes high, can be moved to the second port side to thereby communicate with the second port side, but also a negative pressure valve which, when the pressure on the first port side becomes low, can be moved to the first port side to thereby communicate with the second port side. In the pressure control valve, there is provided flow passage expanding means which, which the positive pressure valve has moved to the second port side beyond a given distance, allows the first port side to communicate with the second port side. Further, the evaporation fuel discharge control device comprises first communicating means which allows the upstream side of a switch valve to communicate with an pressure introduction passage when the pressure on the upstream side of the switch valve is higher by a given value or more than the pressure on the pressure introduction passage side, and second communicating means which allows the upstream side of the switch valve to communicate with the pressure introduction passage when the pressure on the pressure introduction passage side is higher by a given value or more than the pressure on the upstream side of the switch valve.
    • 压力控制阀构造成使得第一端口形成在壳体的一侧上,另一侧形成第二端口,并且在壳体中不仅设置正压阀,当正压力 在第一端口侧变高,可以移动到第二端口侧,从而与第二端口侧连通,而且还可以在第一端口侧的压力变低时能够向第一端口侧移动的负压阀 从而与第二端口侧连通。 在压力控制阀中,设有流动通道膨胀装置,正压阀已经向第二端口侧移动超过给定距离,允许第一端口与第二端口侧连通。 此外,蒸发燃料排出控制装置包括第一连通装置,当开关阀的上游侧的压力高于给定值或大于压力时,允许开关阀的上游侧与压力引入通道连通 在压力引入通道侧的第二连通装置,以及当压力引入通道侧的压力高于给定值或大于上游的压力时允许开关阀的上游侧与压力引入通道连通的第二连通装置 侧开关阀。

    • The process for polymerizing olefins uses a plurality of series-connected polymerization reactors in which at least one of second and subsequent reactors is a vapor-phase polymerization reactor containing a multicomponent gas. The process comprises the steps of: taking the multicomponent gas out of the vapor-phase polymerization reactor; mixing the multicomponent gas with an inert gas which is lighter than at least one component of the multicomponent gas, thereby obtaining a mixed gas; compressing and/or cooling the mixed gas to liquefy a part of the multicomponent gas; discharging at least a part of a gaseous mixture comprising the inert gas and an unliquefied multicomponent gas out of a reaction system; and returning a fluid comprising the remainder of the gaseous mixture and the liquefied multicomponent gas to the vapor-phase polymerization reactor. By mixing the multicomponent gas taken out of the vapor-phase polymerization reactor with the inert gas, the composition of gas in the vapor-phase polymerization reactor is effectively controlled, thereby ensuring a stable production of olefin polymers of a desired molecular weight distribution and composition.
    • 聚合烯烃的方法使用多个串联聚合反应器,其中第二和随后的反应器中的至少一个是含有多组分气体的气相聚合反应器。 该方法包括以下步骤:将多组分气体从气相聚合反应器中取出; 将多组分气体与比多组分气体的至少一种组分轻的惰性气体混合,从而获得混合气体; 压缩和/或冷却所述混合气体以液化所述多组分气体的一部分; 将包含惰性气体的气态混合物的至少一部分和从反应体系排出的未液化的多组分气体排出; 并将包含剩余的气态混合物和液化的多组分气体的流体返回到气相聚合反应器中。 通过将从气相聚合反应器中取出的多组分气体与惰性气体混合,气相聚合反应器中气体的组成被有效地控制,从而确保了所需分子量分布和组成的烯烃聚合物的稳定生产 。
