Core Positioning: More Than a Valve, It's an "Intelligent Early Warning Sentinel" for Wet Fire Protection

Grooved wet alarm valve

The grooved wet alarm valve serves as a key control device in wet pipe fire sprinkler systems. It is designed to maintain stable water pressure within the pipeline under normal working conditions, and automatically initiate water supply and alarm signals once a fire activates the sprinklers. By integrating water isolation, pressure balance and alarm triggering in one structure, it ensures the fire system remains highly responsive and dependable at all times.

Structural Highlights: Grooved Ingenuity, Unlocking Dual Advantages of Efficient Installation and Long-Term Durability

Different from the cumbersomeness and limitations of traditional flange-connected valves, this product adopts an integrated structural design, maximizing practicality and convenience. The valve body is precision-cast with high-strength ductile iron, featuring corrosion resistance, impact resistance and high pressure resistance, which can withstand the constant pressure of the pipeline for a long time without deformation. The grooved connection design eliminates complex welding processes, on-site assembly does not require professional welders, and the splicing speed is more than 60% faster than traditional valves. At the same time, it has better sealing performance, effectively avoiding the hidden danger of pipeline leakage. Internally, it integrates a customized valve clack, pressure compensation hole, retarder interface and pressure gauge seat, with a compact structure that does not occupy additional installation space. The key seals are made of wear-resistant and anti-aging special rubber materials, combined with stainless steel moving parts, which greatly reduces component loss and false alarm probability, and extends the service life of the whole machine.

Working Principle: Pressure Difference Trigger, Realizing Synchronous Linkage of "Water Supply + Alarm"

The core working principle of this product revolves around "pressure balance" and "pressure difference trigger", realizing automatic on-duty and response without manual intervention. In the standby state, the water pressure on the water supply side and the system side maintains dynamic balance, the valve clack is tightly closed, and the pipeline is always in a full-water pressure state, ready for action at any time. When a fire occurs, the sprinkler head breaks due to high-temperature burning, the water pressure on the system side drops sharply, forming an obvious pressure difference with the water supply side, pushing the valve clack to open automatically and supply water to the fire area quickly. At the same time, part of the water flow will be diverted to the alarm pipeline. After filtering the instantaneous water pressure fluctuation (to avoid false alarms) through the retarder, it synchronously drives the hydraulic gong to emit a sharp warning sound and the pressure switch to transmit an electrical signal to the fire control center, realizing "dual audio and electrical alarms" to ensure that fire personnel can get the fire information in the first time and deal with it quickly. After the fire is handled, close the damaged sprinkler, empty the air in the pipeline and restore the pipeline water pressure, the valve clack can reset automatically and return to the standby state, which is easy to operate without complex debugging.

Performance Advantages: Stable, Accurate, Economical and Durable, Adapting to Full-Scenario Fire Protection Needs

Compared with conventional wet alarm valves, this product has achieved multi-dimensional upgrades in performance, completely solving the pain points of traditional valves such as high false alarm rate, cumbersome installation and poor durability. It has outstanding pressure stabilization performance. The built-in pressure compensation hole can real-time balance the instantaneous pressure fluctuation of the pipeline, reducing false alarms caused by water hammer and unstable water pressure from the source, and ensuring the stable operation of the system. It has high alarm accuracy, and only triggers the alarm when the pipeline flow reaches the rated standard, effectively filtering irrelevant interference signals. The installation is convenient and efficient. The grooved quick-connection design greatly shortens the on-site construction period, adapts to the mainstream caliber of DN80–DN200, and does not need additional complex accessories. It has excellent durability. The valve body and internal components have undergone strict anti-corrosion and anti-erosion treatment, which can adapt to the long-term water-filled on-duty scenario, with low maintenance cost and service life 30% longer than traditional valves.
