1.Product features and functions
Features:
1. A check valve is a valve that opens or closes the opening and closing member by the force of the medium flowing to prevent the medium from flowing backward.
2. It is an automatic valve, also known as a check valve, check valve, return valve or isolation valve. It is often used as a bottom valve for pumping devices to prevent backflow of water.
3. The disadvantage is that the resistance is large and the sealing is poor when closed.
Effect:
1. The check valve only allows the medium to flow in one direction and prevents the flow in the opposite direction, which prevents the medium from flowing backwards.
2. The check valve is used in combination with a shut-off valve for safe isolation.
