check alarm valve--What Are the Advantages of the Flange-Type (Wet Alarm Valve/Gate Valve)?

check alarm valve

The flange-type design brings key advantages to check alarm valves (including wet alarm valves and gate valves) in fire protection systems. It enables secure, leak-proof connections to piping-flanges distribute pressure evenly across joints, reducing leakage risks compared to other connection types.

This design allows easy installation and removal: aligning flanges with bolts simplifies assembly, even in tight spaces, and facilitates future maintenance or replacement without disrupting the entire piping system.

Additionally, flange connections support higher pressure ratings, ensuring the valve maintains stability during fire emergencies, making it a reliable choice for wet-pipe fire sprinkler systems.

How to install check alarm valve(wet type)?

Preparation & Positioning

Before installation, gather all necessary tools and inspect the wet alarm valve for damage. Choose an accessible location with sufficient space for operation and maintenance. Ensure the valve is oriented correctly-water inlet and outlet align with the piping system. Prepare the piping by cleaning debris and confirming proper sizing to match the valve's connections, laying the groundwork for a secure setup.

Piping Connection & Sealing

Connect the water supply pipe to the inlet and the sprinkler network to the outlet, using appropriate gaskets or seals for leak-proof joints. Tighten connections gradually and evenly to avoid warping. Install pressure gauges on both the inlet and outlet sides as per the system's design, ensuring they are properly calibrated for accurate pressure monitoring during and after installation.

Alarm Device Integration

Attach the water motor gong and pressure switch to the alarm ports. Ensure the tubing connecting these devices is free of kinks and securely fastened. Test the alarm pathway for blockages by gently flushing water through the alarm line, verifying that the gong and switch can activate smoothly when water flow occurs, which is crucial for timely fire alerts.

System Testing & Adjustment

After installation, conduct a low-pressure test to check for leaks at all connections. Then, perform a full-flow test by opening a test sprinkler or drain valve, observing the alarm activation and water flow. Adjust any components, such as valve settings or alarm device positions, to ensure the system operates reliably, confirming the wet alarm valve functions as intended in fire scenarios.
