Representation method of gate valve type compilation and meaning of gate valve type


Gate valve is a gate with opening and closing parts. The movement direction of gate is perpendicular to the direction of fluid. Gate valve can only be fully opened and closed, and the parameters of gate are different. The gate valve is sealed by force, that is, when the valve closes, it must rely on external force to force the gate to the seat to ensure the sealing of the sealing surface.


Gate Valve Model Meaning:

The compilation description of gate valve model mainly aims at the combination and subdivision explanation of gate valve code, additional requirements, drive, connection, structure, sealing parts, pressure, material and so on.
