High-pressure water mist spray head protection cover

Abstract

The invention discloses a high-pressure water mist spray head protection cover. The high-pressure water mist spray head protection cover provides a preliminary positioning and limiting structure for installation of a spray head, the spray head is driven to move in the X direction and the Y direction, after the final installation position of the spray head is determined, a gypsum board or a wood board is punched, the dismounting link of the gypsum board or the wood board is reduced, meanwhile, a protection piece is provided, and the gypsum board or the wood board is prevented from damaging the spray head in the mounting and dismounting process. A supporting plate is driven by a driving device to move in the Y direction, and the installation position of the spray head in the Y direction is adjusted; and a pressing handle is pressed or loosened, a limiting claw is inserted into or leaves a ratchet tooth groove, the position of the supporting plate in the Y direction is limited, and the position is prevented from being changed. A spray pipe is clamped through a first fixing assembly, the protection piece is clamped through a second clamping assembly, two objects with different diameters are clamped at the same time through one-time operation, and the high-pressure water mist spray head protection cover is simple and convenient to use.

Description

technical field [0001] The invention specifically relates to a protective cover for a high-pressure water mist spray head. Background technique [0002] The fire sprinkler head is used in the fire sprinkler system. When a fire breaks out, the water is sprayed out through the sprinkler splash basin to extinguish the fire. According to the definition in GB5135.1.3.1, a sprinkler is a sprinkler that starts automatically within a predetermined temperature range under the action of heat, or is started by a control device according to a fire signal, and sprinkles water according to the designed sprinkling shape and flow rate. . [0003] High-pressure water mist sprinkler head is one of the important classifications of fire sprinkler heads. High-pressure water mist sprinkler head has small water consumption and good spray effect, which can effectively extinguish fires. The high-pressure water mist sprinkler head includes nozzles and nozzles. During the on-site construction, the g...

AI Technical Summary

Problems solved by technology

The high-pressure water mist sprinkler head includes nozzles and nozzles. During the on-site construction, the gypsum board or wood board is installed on the ceiling truss layer indoors. Open a hole at this position, and then insert the nozzle into the through hole for preliminary positioning of the nozzle. Before the nozzle is finally fixed, the nozzle position needs to be checked again. If the nozzle position needs to be adjusted, the gypsum board or wooden board needs to be removed to complete the spraying. The adjustment of the pipe position is time-consuming and labor-intensive. At the same time, the disassembly of the gypsum board or wood board is very easy to cause damage to the nozzle of the sprinkler head, thereby increasing the cost
