ZST type glass ball closed sprinkler head, sprinkler head model

Type glass ball closed sprinkler nozzle
1. Overview
Type glass ball closed sprinkler nozzle is the most critical component in the automatic sprinkler system. It is an instrument component used to detect fires and is used through automatic Sprinkler equipment to control fires and extinguish live disasters. It is suitable for use in hotels, shopping malls, restaurants, entertainment venues, warehouses, hospitals, factories, airports, basements, etc. where the working environment temperature is not lower than ℃ and not higher than ℃ in medium and light hazardous buildings. It is used as a wet system to use water to extinguish disasters. Pipe network for sprinkler system.
Based on product standards. "Part of Sprinkler Nozzles for Automatic Water Spraying Fire Rescue System"
2. Operating Principle
The operating principle of this series of glass ball sprinkler heads is that the glass ball sprinkler head has a high thermal expansion coefficient. A glass sphere of organic solution serves as a thermally sensitive element. At normal temperature, its glass ball shell can receive a certain amount of support to ensure the sealing of the nozzle. When a fire occurs and the temperature increases, the organic solution in the glass ball thermally expands and generates a large internal pressure until the shell of the glass ball breaks, and then the nozzle is opened to spray water.
3. Structural Features
This series of glass ball sprinkler nozzles are made of copper alloy structure, glass balls, seals, glass ball seats, set screws and splash plates. Compact structure, exquisite and beautiful appearance.
. The nozzle structure is precision cast with high-strength copper alloy, which has high strength and good corrosion resistance.
. The temperature-sensitive element (glass ball) is made of high-quality products at home and abroad. The glass ball has high strength, reliable action and fast response speed.
. This series of glass ball sprinklers have been inspected by the National Fixed Fire Fighting System and Fire-Resistant Component Quality Supervision and Inspection Base to meet the requirements of the national standard "Part Sprinklers for Automatic Fire Fighting Systems".
