1. The glass ball sprinkler head is a key thermal sensitive element in the Automatic Sprinkler System. Mae'r bêl wydr wedi'i llenwi â datrysiadau organig gyda chyfernodau ehangu gwahanol. After thermal expansion at different temperatures, the glass ball is broken, and the water in the pipeline is sprayed upward, downward, or to the side of the splash tray with different designs, so as to achieve the purpose of automatic sprinkler. It is applicable to the pipe network of automatic sprinkler system in factories, hospitals, schools, machine shops, hotels, restaurants, entertainment places and basements where the ambient temperature is 4° C~70° C.
3. Structural characteristics Closed glass ball sprinkler is composed of sprinkler head, fire glass ball, splash tray, ball seat and seal, set screw, etc. After passing the full inspection of 3MPa sealing test and the qualification assessment of sampling inspection items, the Mae sgriw gosod wedi'i gadarnhau â glud a'i gyflenwi i'r farchnad i'w gosod yn rheolaidd. Ar ôl ei osod, ni chaniateir iddo ail -ymgynnull, dadosod a newid.
The product is composed of a glass ball nozzle (1), a screw socket (2), a housing base (3) and a housing cover (4). The nozzle and the screw socket are installed together on the pipeline of the pipe network, and then the cover is installed. The housing base and the housing cover are welded together by fusible alloy. When a fire occurs, the ambient temperature rises. Pan gyrhaeddir pwynt toddi'r aloi fusible, bydd y clawr yn cwympo i ffwrdd yn awtomatig. With the continuous increase of temperature, the glass ball of the nozzle in the cover will break due to the expansion of the temperature sensitive liquid, so that the nozzle can be started to spray water automatically.

Prif Strwythur ac Egwyddor Weithio Mae'r llif dŵr yn rhuthro allan o'r sedd sêl ac yn dechrau chwistrellu dŵr i ddiffodd y tân. Under a certain amount of water flow, the water flow indicator starts the fire pump or alarm valve, starts to supply water, and continues to spray water from the opened sprinkler head to achieve the purpose of automatic sprinkling.
