Firefighting pressurizing sprinkler head

Abstract

The invention discloses a firefighting pressurizing sprinkler head which comprises a spraying head base, a glass body and a water spraying disc. A pressurizing cavity is formed in the spraying head base. A spraying hole is formed in the front end of the spraying head base and communicates with the front end of the pressurizing cavity. A plunger is inserted into an inner cavity of the spraying hole in a connected manner. A rubber sealing pad is arranged between the plunger and the spraying hole. The water spraying disc comprises a water spraying outer disc and a water spraying inner disc. The water spraying inner disc is located in an inner cavity of the water spraying outer disc. Balls are clamped between the water spraying outer disc and the water spraying inner disc. A glass body fixing base is arranged in the middle of the water spraying inner disc. A plurality of water spraying wings are uniformly arranged on the surface of the water spraying outer disc. The glass body is installed between the plunger and the glass body fixing base. The water spraying inner disc is fixedly connected with the spraying head base through an arm frame. The firefighting pressurizing sprinkler head is simple in structure, convenient and practical, fully utilizes water pressure to carry out firefighting, enlarges the spraying range and reduces damage to the water spraying disc.

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...

AI Technical Summary

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
