Problems solved by technology

[0003] However, the existing fire sprinklers are generally fixed-flow sprays, and the spray volume and spray effect per unit time are fixed. When the fire is small, the spray volume is greater than the spray volume required to extinguish the fire. , resulting in the waste of water resources, and expanding the scope and degree of dampness of the corresponding facilities and items. When the fire is large, the amount of spraying is less than the amount required to extinguish the fire, which makes it difficult to extinguish the initial fire, which relatively speeds up the fire. The speed at which the spread spreads, which in turn increases the severity of the fire

Abstract

The invention provides a self-adjusting flow control valve for fire sprinkler, which belongs to the technical field of flow control valves and includes a valve body and an adjusting seat. There is an annular through hole corresponding to the drive rod, the adjusting pipe seat is fixedly embedded in the annular through hole, the adjusting assembly is slidingly embedded in the adjusting pipe seat, and the side of the partition plate away from the adjusting pipe seat is provided with an annular through hole. Corresponding to the on-off plate, the adjustment seat is provided with a connecting air bag, and the connecting air bag is respectively connected with the sealing chamber and the detection reaction air bag. The self-adjusting flow control valve for fire-fighting sprinkler can automatically adjust the water volume of fire-fighting sprinkler according to the needs of the fire by detecting the combined action of the reaction air bag, sealing chamber, driving rod, sealing plate, and adjusting components, and effectively fights the fire at the initial stage. While preventing fire or suppressing the spread of fire, a large amount of water resources are saved, thereby improving the utilization rate of resources.

Description

technical field [0001] The invention relates to the technical field of flow control valves, in particular to a self-adjusting flow control valve for fire sprinkler. Background technique [0002] Fire sprinkler is a widely used fixed fire extinguishing device. When a fire occurs, the sprinkler can be automatically turned on to control and extinguish the initial fire in a timely and effective manner, reducing the probability of fire spread or the severity of the fire, and correspondingly improving Ensure the safety of fire sprinkler covered places. [0003] However, the existing fire sprinklers are generally fixed-flow sprays, and the spray volume and spray effect per unit time are fixed. When the fire is small, the spray volume is greater than the spray volume required to extinguish the fire. , causing waste of water resources, and expanding the scope and degree of dampness of the corresponding facilities and items. When the fire is large, the amount of spraying is less than...
