Due to the continuous advancement of technology, the safety performance of various gate valves is also continuously improved. The double gate valve is equipped with a valve stem protective sleeve to prevent the valve stem from being corroded by the medium; the shell adopts a specially designed "squirrel cage frame type stiffener", which reduces the overall weight of the valve and improves the strength and strength of the shell. Rigidity: The elastic sealing gate valve adopts elastic hard seal. When the valve is fully opened or fully closed, the sealing ring completely isolates the medium from the inner cavity of the valve, so that the gate valve has the properties of fire resistance, high temperature resistance, and corrosion resistance. The gate valve with fully enclosed opening and closing indicator allows the operator to have a clear understanding of the valve status.


The ball valve also has fire resistance and high temperature resistance. The high temperature after the fire burned the PTFE material on the sealing seat. The metal sealing seat and each sealing part can form a metal-to-metal sealing structure to prevent the diffusion of gaseous media and prevent the disaster from continuing to expand; in addition, solenoid valve water valve It also has an anti-static structure, so that the static electricity generated during the starting and closing of the ball valve can be introduced into the ground, to avoid static electricity from accumulating the ignition medium, and to ensure the safety of the equipment; the ball valve limited position locking mechanism can prevent the operator from misoperation or illegal operation.


The isolation width of the sealing gasket of the butterfly valve is too narrow, which will easily cause overheating or not in place when closing the disc, which will affect the sealing; in addition, because the inside of the sealing ring is divided into rubber or PTFE, it is easy to be damaged or fall off when the gas is scoured, and it will be fire It is easily damaged in high temperature and has a short service life.


So no matter from which point of view, the pilot solenoid valve is not suitable for buried gas pipelines. However, due to space constraints, only butterfly valves can be selected. The butterfly valve selected should be a high-quality multi-eccentric butterfly valve, and the sealing material should be PTFE or hard seal, which must be accurately adjusted to the closed position during commissioning.
