一 用途 Application
球阀是一种管线阀门产品，用于接通或截断管路中的介质。一般是处于全开或全关状态，在微开状态下可作流量的调节使用。广泛适用于工况条件下水、气、油品等介质的各种管路中。
Ball valve is pipeline valve, used for connecting or cutting off medium in the pipelines. Normally it is at the state of opening or closing. And it could function as regulating the flow when it is at the state of slightly open. It is used on the pipeline such as water, gas, oil etc.
