Brief Analysis of Five Aspects of Valves and Pipelines

1. When the fire pump outlet pipe diameter is greater than 300mm, a single manual opening and closing function valve should not be used. The valve should have a clear opening and closing sign, remote control valve should have a quick opening and closing function, and reliable sealing.

2. Normally open or normally closed valves should be equipped with locking devices. Control valves and valves that need to open and close should have open and close indicators. Participate in the remote control gun linkage control valve, the opening and closing signal should be transmitted to the system control room.

3, the valve on the dry powder pipeline should use ball valve, its diameter must be consistent with the pipe diameter.

4, the pipeline should be made of corrosion-resistant materials or anti-corrosion treatment on the outer wall of the pipeline.

5. Flushing connections should be provided in the appropriate locations where the foam, foam mixture or seawater are used. An automatic exhaust valve should be provided at the top of the pipe section where air may be trapped.

6. A bypass test interface should be provided after the foam ratio mixing device.
