Sprinklers and sprinkler systems

Abstract

The spray head and water spray system claimed in the present invention, the spray head includes a spray head body, and the flow channel hole is opened on the spray head body, wherein the flow channel hole includes an inlet part, a constriction part and an outlet part connected in sequence; The main body of the spray head is movably connected with a movable rod at the position of the outlet part, and the outer diameter of the movable rod is smaller than the aperture of the outlet part, so that the water in the flow channel hole can pass through the movable rod wherein the movable rod is provided with a diversion hole; the main body of the nozzle is connected with a pipe joint, and the pipe joint communicates with the diversion hole on the movable rod, and the pipe joint can flow to the The diversion hole of the movable rod is connected with water; the movable rod can move with the water passing through the pipe joint, so that the diversion hole on the movable rod communicates with the necking part. The present invention realizes the self-dragging function of the spray head through reasonable structural arrangement.

Description

technical field [0001] The invention belongs to the technical field related to water spraying, and in particular relates to a spray head and a spraying system. Background technique [0002] Nozzles are usually used to produce water. At present, in the process of coke preparation, enterprises need to pump water into a water tank with a height of tens of meters above the ground, and then spray the water in the water tank downwards with the nozzle to prevent the coke from being prepared. Coke dust, cooling. [0003] Among them, the above-mentioned nozzles used for spraying water have a large overall size, and the water in the water tank is inevitably mixed with granular impurities, so that the nozzles are prone to fouling in the flow channel holes of the nozzles during long-term use. , and can block the necking part of the flow channel hole of the nozzle from a large diameter to a small diameter. At present, in view of the above existing technical problems, the flow channel h...

AI Technical Summary

Problems solved by technology

Because there is a lot of dust in the environment where the nozzle is installed, and the height from the ground is tens of meters, it greatly increases the labor intensity of the workers, and there are certain hidden dangers to the personal safety of the workers. Dredging, its efficiency is poor, and it cannot meet the needs of enterprises
