Glass bulb sprinklers is "automatic sprinkler system" in the critical heat sensitive components, glass sphere filled with an organic solution of different coefficients of expansion, after different temperature by thermal expansion, broken glass spheres, different water sprayed inside the pipeline Design deflector up, down or sideways spraying fire closed nozzle side, so as to achieve the purpose of automatic sprinkler. Suitable for ambient temperature of 4 ° C ~ 70 ° C in factories, hospitals, schools, shopping malls taste machine hotels, restaurants, entertainment and basement sprinkler system pipe network. Dry System features ①. Dry sprinkler system open and closed within the pipe network after the alarm valve water, it is possible to avoid the danger of freezing and moisture constraints from environmental temperature, it can not be used in some wet place system. ②. Higher than the wet system investments. Inflatable because of the need to increase the set of inflatable equipment and increase the system cost. ③. Construction and maintenance management dry system is more complex closed nozzle principle of the airtight pipeline have more stringent requirements, usually pipe pressure should be maintained at a certain range, when the pressure drops below a certain value closed nozzle , you need to be inflated. ④. Sprinkler slower than a wet system, because the nozzle heating is turned on, we must first exhaust the gas pipeline, and then the water, which delayed the time.
