Company Project
UL FM fire sprinkler heads usually use glass balls filled with organic solutions with a relatively high coefficient of thermal expansion as thermal sensitive elements. At normal temperature, the glass ball shell can withstand a certain supporting force to ensure the sealing of the nozzle. When a fire breaks out and the temperature rises, the organic solution inside the glass ball expands due to heat, generating a significant internal pressure until the outer shell of the glass ball breaks, thus opening the nozzle to spray water.
It is generally assembled from a copper alloy frame, glass balls, seals, glass ball seats, set screws and splash trays, etc.UL FM Fire Sprinkler Head is a precision-engineered, life-saving device. Its certification by both UL and FM Approvals is a non-negotiable requirement, providing the highest assurance that it will perform reliably to control a fire, protect lives, and minimize property damage. The correct selection of type, temperature rating, and style is governed by NFPA 13 and is critical to the system's effectiveness.
Features
• The nozzle frame is precisely forged from high-strength copper alloy, featuring high strength and excellent corrosion resistance.
• The temperature-sensing thermosensitive element (glass ball) adopts high-quality products, featuring high strength, reliable operation and fast response speed.
