Product introduction
First, the product description
Glass ball sprinkler sprinkler system is one of the most critical components, instruments used to detect the fire element, and through the automatic sprinkler systems to control the fire and put out the fire.Is suitable for the job not less than 4 ℃, environment temperature and level is not higher than 70 ℃ in light dangerous buildings as the wet system with water to put out the fire of hotel, restaurant, shopping malls, entertainment venues, warehouses, hospitals, factories, airports and the basement of the automatic sprinkler system pipe network.
Product standard basis: GB5135.1-2003 1 part of the automatic sprinkler system sprinkler"
Second, the principle of work
The working principle of the series of glass ball sprinkler is filled with glass balls of the thermal expansion coefficient of high organic solution as a thermal sensitive element.At room temperature, the glass ball shell can absorb a certain amount of support, to ensure that the nozzle seal.When temperature increases, when the fire broke out in the organic solution of thermal expansion and glass ball that generates a lot of pressure, until the broken glass ball shell, so as to open the nozzle spray.
Three, structure features
This series of glass ball sprinkler is composed of copper alloy frame, glass ball, seals, glass ball, set screws and splash plate assembly.Compact structure, beautiful appearance is exquisite.
1, nozzle framework USES the high strength copper alloy precision forging, high strength, good corrosion resistance.
2, thermal heat sensitive components (ball) with high quality products at home and abroad, the glass ball with high intensity, reliable, fast reaction.
3, the series of glass ball sprinkler by national fixed fire extinguishing systems and fire-resistant components of quality supervision inspection center standards GB5135, 1-2003 "the automatic sprinkler system part 1: sprinkler" paragraph.
Four, flow coefficient K = 80 traffic pressure curve
