Eaves-type water curtain sprinklers are used to prevent threats to the eaves when a fire breaks out in adjacent buildings or to increase the fire resistance of the eaves. Water curtain sprinklers are installed to sprinkle water on the eaves. Cornice-type water curtain nozzles are one of the important components in the fire protection system. They are usually combined with deluge alarm valves, water supply pipe networks and detection alarm devices to form a water curtain fire protection system.

Cornice type water curtain nozzle specifications and models:

The cornice-type water curtain sprinkler model is commonly represented by ZSTM, where ZS represents the automatic sprinkler device, T represents the sprinkler head, and M represents the water curtain sprinkler type. In addition, the structural characteristics and uses of water curtain nozzles are as follows:

①Type A: represents a water curtain nozzle with a water curtain inclination angle (the angle between the nozzle inlet axis and the water outlet axis) of 0°.

②Type B: Indicates a water curtain nozzle with a water curtain inclination angle of 90° and only one water outlet.

③Type C: represents a water curtain nozzle with a water curtain inclination angle of 90° and two water outlets.

④D type: indicates a water curtain nozzle with a water curtain inclination angle other than 0° or°.

⑤Type G: Indicates water curtain nozzles only suitable for fire separation.

⑥L type: Indicates water curtain nozzles only suitable for protection and cooling.

⑦T type: Indicates a universal water curtain nozzle suitable for fire separation, protection and cooling.

The following is a general selection table for cornice-type water curtain sprinklers:

Cornice type water curtain nozzle application scenarios:

Due to the action of pressure water, the cornice-type water curtain nozzle quickly forms a water curtain with the inflowing water, sprays it out at a certain speed, and evenly sprays it within the corresponding range according to a certain atomization angle, covering the outer surface of the protected object. It has the functions of cooling, suffocation, emulsification, dilution, insulation, etc., to suppress the fire and extinguish the fire. Commonly used in the following scenarios:

1. For fire separation: can be used around stages, windows, escalators, spiral stairs and building atriums;

2. For protective cooling: It can be used in fireproof roller shutters, glass curtain walls, fire doors, steel components and other places.

Cornice type water curtain sprinkler product features:

● Limit the burning speed, reduce fire damage, reduce explosion risks, and promote vapor dilution and dispersion.

● Only water is used as fire extinguishing agent, which is very economical.

● If liquid fire is required to be extinguished, clean water foam can be introduced into the mixer.

● Can be effectively used in conjunction with other fire extinguishing systems.

Cornice-type water curtain nozzle flow rate and injection curve:

The ejection flow rate of the cornice-type water curtain nozzle is different under different pressures. The following is its flow characteristic curve:
