First, the use:
The ZSTWB high-speed water mist nozzle is a component of the water mist sprinkler system. It usually consists of a control valve (such as a deluge valve, a manual valve), a water supply pipe network, and a detection and alarm device to form a water mist fire extinguishing system. The B-type water mist nozzle is a centrifugal atomizing nozzle in which the water inlet and the water outlet are in a straight line. It is mainly used for liquid fires and electrical fires with solid fires and flash points above 60 °C, as well as for protective cooling of flammable gases and liquid storage facilities of Class A, B and C liquids. It is widely used in power plant power generation equipment, point motors, Large transformers, oil tanks, etc.
Second, special features:
The water mist nozzle produced by the company is characterized in that under the action of a certain water pressure, the inflowing water is decomposed into small mist-like water droplets, and is uniformly sprayed on the outer surface of the protection object at a certain speed according to a certain atomization angle. Achieve fire control and fire fighting. It can be mounted in the vertical direction and installed horizontally as needed. The nozzle is a combination of integral type, the material is made of high quality brass, and the surface is polished and chrome-plated. High strength, strong corrosion resistance, compact structure and beautiful appearance.
Third, the main technical parameters:
1. Model specifications are as follows:
2, nozzle performance characteristics curve
Fourth, installation and maintenance considerations:
1. According to the installation form, this product can be adjusted according to the use requirements: vertical spray, vertical spray, horizontal spray, or spray at a certain angle, forming a uniform water mist when spraying.
2. The water mist nozzles are all open type. In order to ensure the atomization effect, the working water pressure of the nozzles cannot be lower than 0.35MPa.
3, the nozzle should be kept clean, spray paint, paint, etc. are strictly prohibited.
4. Before the nozzle is installed, the pipeline should be flushed according to relevant regulations.
Five, tips:
According to different atomization angles (60°, 90°, 120°), the spray test is actually carried out. The nozzle with the same K-factor nozzle atomization angle is farther than the nozzle with large atomization angle. Therefore, it is recommended that the designer should Reasonably select the atomization angle of the nozzle.
