Use

The check valve can automatically prevent the liquid from converse, after its valve disc is ipen by the liquid pressure, the liquid flows from inlet to outlet, and when the inlet pressure is lower than that of outlet, the valve disc will automatically shut to prevent the liquid from converse under the action of liquid pressure difference and its own heaviness.
