PRODUCTS CENTER
The sprinkler head is the most critical component of an automatic sprinkler fire suppression system. It is used to detect fires and control and extinguish fires through an automatic sprinkler system. This series of products is assembled from a copper alloy frame, actuating element (glass bulb/fusible alloy), seals, seat, set screws, and splash plate, etc. It features a compact structure and exquisite appearance.

The ZSFZ wet alarm valve is a one-way valve that only allows water to flow into the sprinkler fire suppression system in one direction, and drives the associated components to alarm under specified pressure and flow rate. It forms a widely used wet automatic sprinkler fire suppression system together with a water flow indicator, a signal valve, a pressure switch, a sprinkler head, etc. This system is in standby operation for a long time, with the pipe network filled with pressurized water. When a fire occurs in the protected area, the ambient temperature rises, causing the temperature-sensitive element on the sprinkler head to activate, the sealing component falls off, and the system automatically starts, spraying water directly to the fire area and issuing an alarm signal to achieve the purpose of alarm, fire extinguishing, and fire control.

A pre-action device consists of a pre-action alarm valve group, a control panel, a pressure maintaining device, and an air supply device. It is a one-way valve group device that allows water to flow into the sprinkler system in one direction while simultaneously sounding an alarm through electric, pneumatic, mechanical, or other methods. A pre-action device, together with closed sprinklers, inflation equipment, water supply facilities, and pipes, constitutes a pre-action system. In the standby state, the water distribution pipes are not filled with water. Depending on the application of the pre-action system, there are two automatic control methods for the pre-action device: one is activated only by a signal from the fire alarm system, and the other is activated by signals from both the fire alarm system and a pressure switch installed on the inflation pipe.
