Check insulation, also known as reflux valve, check valve, back pressure valve, check valve. Such valves are in the pipeline by the force generated by the flow of the medium itself automatically turned on and off, is an automatic valve. Check for the pipeline system, its main role is to prevent the media back, to prevent the pump and its drive motor reverses, and discharge the container media. Pressure valve can also be used for more than one of the primary system pressure may rise to an auxiliary system supplies the pipeline. In order to prevent water hammer hidden pipe insulation valve, over the years, people in the check valve design, using a number of new structures, new materials, to ensure the valve is suitable performance, while the impact of the water hammer minimized has made encouraging progress. Check valve means relying on the media itself flows automatically open and close the valve Shandong valve to prevent the media back valves, check valves are an automatic valve, whose main role is to prevent the media back, to prevent the pump and drive motor back Weifang turn valves, and discharge the container media. Also known as a one-way check valve or check valve, its role is to guard the line of medium back. Pump water off the bottom valve also belongs to check class. Opening and closing pieces by the media activity and strength to turn itself on or closed to prepare for the media called backflow check valve. Check valves are active valves BH44H Check insulation manufacturers, it is important to check the activities of the media channels, allowing only a bias towards media campaign to generate accident preparedness.
