三種不同的連接方式

截止閥按照不同的連接方式被分為三種。有法蘭連接、絲si扣kou連lian接jie和he焊han接jie連lian接jie。這zhe三san種zhong不bu同tong的de連lian接jie方fang式shi都dou有you各ge自zi不bu同tong的de優you點dian。法fa拉la連lian接jie的de方fang式shi目mu前qian在zai國guo內nei還hai沒mei有you普pu遍bian的de應ying用yong。絲si扣kou連lian接jie比bi較jiao方fang便bian安an裝zhuang，小xiao巧qiao，但dan是shi承cheng受shou的de壓ya力li也ye比bi較jiao小xiao

截止閥是安全工程的最後一道保護障
