A marine stainless steel valve is a device used to control the pressure, flow and flow direction of the fluid in the ship's pipeline to meet the environmental conditions of the ship. A valve is the control device of the fluid pipeline. Its basic function is to connect or cut off the flow of the medium in the pipeline, change the flow of the medium and the flow direction of the medium, adjust the pressure and flow of the medium, and protect the normal operation of the equipment...

Overview The thermal adhesion of the gate valve refers to the phenomenon that the valve is closed in a hot state, and cannot be opened after cooling. Two main reasons When the valve is closed, the valve stem extends from the external low-temperature area to the high-temperature area inside the valve body. With the gradual heating of the valve stem, a small amount of deformation will occur in both the axial and radial directions, and the axial deformation will generate a force F1, which further...

1. An introduction to marine valves A marine valve is a device used to control the fluid pressure, flow and flow direction in the ship pipeline in order to meet the environmental conditions of the ship. It is currently widely used in various systems of the ship. The unique working environment of ships makes marine valves different from ordinary valves, forming an independent system. The differences between marine valves and ordinary valves are reflected in the aspects of shapes, weights and materials....
