Applied Research Of Direct Buried Ball Valve In Urban Gas High-Pressure Pipeline

City gas pipeline network which is essential equipment is the valve.According to the installation is divided into two kinds,wells and valves directly buried.In practical application,the wells have practical problems and difficulties in water,land,engineering costs,operational security.All-welded ball valve can solve these problems.This paper studies and analyzes the current application status of gas pipeline valves,application of High Pressure Direct Buried Valve in Urban Gas,as a reference in the future application of urban high-pressure direct-buried gas pipe network.
