Firefighting pressurizing sprinkler head

Abstract

The invention discloses a fire-fighting pressurized sprinkler head, which comprises a sprinkler seat, a glass body and a sprinkler tray. A pressurized cavity is arranged inside the sprinkler seat, and a spray hole is arranged at the front end of the spray head seat. The spray hole and the booster The front end of the pressure chamber is connected, and a plug is plugged into the inner cavity of the spray hole, and a rubber sealing gasket is arranged between the plug and the spray hole. Located in the inner cavity of the water sprinkling outer plate, balls are clamped between the water sprinkling outer plate and the water sprinkling inner plate, the middle part of the water sprinkling inner plate is provided with a glass body fixing seat, and the surface of the water sprinkling outer plate is evenly provided with several sprinkler fins, the The glass body is installed between the plunger and the glass body fixing seat, and the sprinkler inner plate is fixedly connected with the nozzle seat through the arm bracket. The invention is simple in structure, convenient and practical, fully utilizes the water pressure for fire extinguishing, expands the spraying range, and reduces the damage of the water pressure to the sprinkler tray.

Description

Technical field [0001] The invention relates to the technical field of fire-fighting sprinklers, in particular to a fire-fighting booster sprinkler. Background technique [0002] At present, fire is still one of the important accidents that affect people's property and personal life. In order to effectively avoid the spread of fire after a fire occurs, most of the buildings or indoors are installed with fire-fighting sprinklers. The water pressure of the sprinkler is used to form fire-fighting water mist to extinguish the fire. However, the sprinklers of the existing sprinkler heads are fixed, and the water column sprayed from the nozzle holes and the diffuser are violently impacted, consuming a lot of energy. And cause damage to the sprinkler pan, make the spray range smaller, so that the fire extinguishing range becomes smaller, and the water energy cannot be fully utilized. Therefore, it is necessary to design a fire-fighting booster sprinkler head. By setting a rotatable spri...

Problems solved by technology

The sprinkler plate uses water pressure to form fire-fighting water mist to extinguish the fire. However, the sprinkler plate of the existing sprinkler head is fixed, and the water column sprayed from the spray hole will have a violent impact with the water plate, consuming a lot of energy. And cause damage to the sprinkler plate, so that the spraying range becomes smaller, so that the fire extinguishing range becomes smaller, and the water energy cannot be fully utilized. Therefore, it is necessary to design a fire booster sprinkler head. By setting a rotatable sprinkler plate, it can fully The use of water pressure for fire extinguishing greatly improves the spraying range of the sprinkler head and reduces the loss of the high-pressure water column to the sprinkler tray
