What is the principle and working mode of American standard gate valves?
American standard gate valve, also known as American standard valve, is a commonly used gate valve used to control fluid flow. The principle of American standard gate valves is to control the flow of fluid in pipelines by moving the sealing surface inside the valve. The main working method of American standard gate valves is to open or close the valve manually or electrically, in order to control the flow of fluid.
The main components of American standard gate valves include the valve body, valve cover, valve stem, sealing surface, and transmission device. The valve body is the main body of the gate valve, and American standard globe valve manufacturers can choose the inlet and outlet according to the flow direction of the fluid. The valve cover is used to fix the valve stem, and the valve stem is connected to the valve cover through a transmission device. The valve can be opened and closed by rotating or pushing and pulling. The sealing surface is used to seal the internal space of the gate valve and prevent fluid leakage.
The working principle of American standard gate valves is to move the valve stem and valve seal towards the inside of the pipeline through manual or electric operation, thereby controlling the flow of fluid. When the valve stem and valve move downwards, the sealing surface contacts the valve seat, and the valve closes; When the valve stem and valve move upwards, the sealing surface separates from the valve seat, and the valve opens. By continuously adjusting the valve opening, American standard globe valve manufacturers can accurately control the fluid flow rate and flow rate.
Overall, American standard gate valves are a commonly used fluid control valve that can be opened and closed manually or electrically to control fluid flow. Its principle is simple, structure is stable, performance is reliable, and it is widely used in various industrial fields.
