The stopper valve refers to the valve that is automatically opened and closed by automatic opening and closed valve to prevent the medium from flowing by the medium.The stopper valve is an automatic valve, which is the main function of preventing the medium backflow, preventing pumps and driving motor reversal, and leakage of container media.
Stop valve price
Stop valve symbol
Rotating and stopping valve.This valve is suitable for large -caliber occasions with low flow speed and small flow changes. According to the valve caliber, it consists of three types: single -petal, dual -petal, and multi -type. It can weaken the impact of hydraulic and prevent the media from stop flowing or inverted.Lift -down stop valve.This valve can only be installed on a horizontal pipe, and its fluid resistance coefficient is large to prevent the media from flowing.Among them, the vertical lifting back valve, the flow resistance is relatively small.
Stop valve model
1. According to national standards "GB/T12221-2005 Metal Vallest Structure length", the long series is 290mm, and the short series is 216mm.2. Check the sample, the value is 216mm.
The role of stop valve
Main effects 1. For clamping stop valve: When our stop valve is installed in the pipe device, its function is to stop our media flow. Choose different materials.Many kinds of mediums to prevent flowing from flowing. This main material is carbon steel and low -temperature steel.Its main feature is that the valve petals are closed quickly, the period of use is longer, and the performance is more reliable.
Principles of stop valve
The one -way stop valve stop valve refers to the valve that automatically opens and closed the valve flap automatically by flowing by the medium to prevent the medium, also known as the inverse valve, one -way valve, reverse flow valve, and back pressure valve.The stopper valve is an automatic valve, which is the main function of preventing the medium backflow, preventing pumps and driving motor reversal, and leakage of container media.The role of this type of valve is that only allows the medium to flow in one direction and prevent the direction from flowing.Usually this kind of valve is operated automatically. Under the action of fluid pressure flowing in a direction, the valve petals are opened; when the fluid is flowing in the opposite direction, the self -overheating valve flap of the fluid pressure and the valve petals act on the valve seat, thereby cutting the flow.
