Description

Technical Field

[0001] This utility model relates to the field of spray pipe technology, specifically a spray pipe that can limit the water flow threshold. Background Technology

[0002] A sprinkler pipe is a component of a fire protection system. It is used to connect water pipes that can spray water. After water is introduced into the sprinkler pipe, it is sprayed out through nozzles that are evenly distributed at the bottom of the sprinkler pipe to extinguish fires.

[0003] The existing Chinese utility model patent with publication number CN219921913U discloses a spray pipe with a flow-limiting function, including a pipe body, with branch pipes evenly installed at the bottom end of the pipe body. Each branch pipe has a flow-limiting structure inside, and a threaded mounting seat is installed at the bottom end of each branch pipe. A spray head is installed at the bottom end of each threaded mounting seat, and a sealing structure is provided on the outer wall of each threaded mounting seat. Filter structures are provided on both sides of the inside of the pipe body. This utility model, by setting a flow-limiting structure at the top of the branch pipe, allows water from the pipe body to be introduced into the spray head and sprayed out. The flow-limiting structure limits the amount of water sprayed by the spray head, allowing for adjustment of the water volume. In actual use, the water volume can be controlled according to actual needs to avoid water waste, making it more practical.

[0004] Currently, flow restriction structures in pipelines are generally controlled by flow control valves, while sprinkler pipes are usually suspended from the ceiling. Existing flow control valves are large and difficult to install. At the same time, existing flow restriction structures cannot adjust the flow rate according to real-time temperature, which is very inconvenient to use. Utility Model Content
