High pressure check valve
A check valve is used in the hydraulic system and is designed to prevent a change in the direction of fluid flow in the pipeline. The check valve, by passing the liquid in one direction, prevents its return passage. Thanks to the installation of hydraulic shutoff valves, the pipeline, pump, equipment installed on the equipment are protected. A check valve can be used when combining the working pipelines of pumps, for this purpose one or more valves are installed on each line, which allows protecting the system during pressure surges or when it falls in case of an accident.
Balls, plates or cones are used as locking element both with elastic seal and without it. Saddle bearing surfaces ensure full tightness of the connection.
Principle of operation of the check valve
The check valve operates in automatic mode, if there is no liquid movement in the pipeline, the slide valve under its own weight or with the help of a spring is in the closed position, as soon as the liquid begins to move inside the pipeline, the shutter opens, letting the liquid through. As soon as the pressure drops to the low point, the check valve gate automatically closes, the gate is pressed by pressure, preventing the passage of liquid in the opposite direction.
