The one -way valve is the stop valve that allows flowing substances to flow from the water inlet and prevent the medium that keeps flowing from the water inlet and prevent the water outlet from flowing back.The one -way valve is only suitable for controlling the flow of liquid medium. For the medium with strong solid particles and strong adhesion, the unidirectional valve is not suitable.
One -way valve structure
1) Divide the structure: lifting one -way valve, butterfly unidirectional valve, and rotating unidirectional valve.2) Lift and one -way valve: vertical one -way valve, horizontal unidirectional valve.3) Rotating one -way valve: single -petal unidirectional valve, double -petal unidirectional valve, and multi -petal unidirectional valve.4) Divide in the form of connection: thread connection unidirectional valve, welding unidirectional valve, and flange unidirectional valve.
One -way valve type
The types of one -way valve are: 1. Spring type 2. Gravity type 3. Rotal formula 4. Plastic diaphragm 1. One -way valve is generally applicable to a clean medium, and it should not be used for medium with large solid particles and viscosity.2. For low-voltage unidirectional valves below DN50mm, a butterfly one-way valve, a vertical lifting unilateral valve and a diaphragm-type unidirectional valve should be selected.Valve; for a low-voltage unidirectional valve of DN50-DN2000, a butterfly one-way valve and diaphragm-type unidirectional valve should be selected.3. The septum unidirectional valve is suitable for pipes that are prone to water strikes. The diaphragm can well eliminate the water shock generated when the medium is reversed.
Unidirectional valve model
One -way valve principle
The one -way valve is an automatic valve that prevent the medium from flowing backwards. The automatic switching valve flap is used by the flow of the medium. It mainly acts to prevent the drive of the motor from reversing, container media leakage, and the backflow of the medium.You can also increase the pipelines that are supplied by the auxiliary system given by the system by improving the pressure.From a medium that flows in one direction, driven by this pressure, the valve petals are automatically opened. When the medium flows back, the pressure of this flow drives the valve petals to close it, thereby cutting off the reflux of the media.
