Water curtain nozzles added to prevent fire from spreading and expanding through windows or to enhance the fire resistance of window sash, fire shutters, and fire curtains are commonly called window-type water curtain nozzles. Window-type water curtain nozzles can continuously spray water to form a water curtain. They are mainly used for fire separation or cooling. They are an important component of automatic or manual water curtain systems. They are usually combined with automatic (deluge valves and small temperature-sensing deluge valves) or manual control valves, water supply pipe networks, and detection and alarm devices to form a water curtain automatic fire protection system.

Window type water curtain nozzle specifications and models:

Model: ZSTMB-G

The following is a selection table of conventional models of window-type water curtain nozzles:

Window type water curtain nozzle application scenarios:

When the fire separation between buildings does not meet the requirements, window-type water curtain nozzles can be installed on adjacent doors, windows, openings, etc. to enhance the fire protection and fire resistance of walls, doors, windows, door panels, fire shutters, etc., and can play a certain fire barrier role.

Window-type water curtain nozzles are suitable for fire partitions and cooling in large factories, workshops, halls, theaters, stages and building doors, window openings or between adjacent buildings.

Water curtain nozzle types:

According to the structure and purpose: curtain-type water curtain sprinklers, window-type water curtain sprinklers and cornice-type water curtain sprinklers; among them, curtain-type water curtain sprinklers are further divided into gap-type water curtain sprinklers and rain-type water curtain sprinklers.

According to the purpose of use: fire separation water curtain nozzles and protective cooling water curtain nozzles

Rules for formulating water curtain nozzle models:

The structural feature codes and usage feature codes of the water curtain nozzle 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.
