玻(bo)璃球(qiu)灑(sa)水(shui)噴(pen)頭(tou)是(shi)自(zi)動(dong)(dong)噴(pen)水(shui)滅火(huo)系(xi)統中(zhong)的關鍵部件(jian)，能(neng)起(qi)到(dao)探(tan)測(ce)火(huo)警自(zi)動(dong)(dong)啟(qi)動(dong)(dong)噴(pen)水(shui)滅火(huo)系(xi)統的重要作(zuo)(zuo)用(yong)。通(tong)常安裝于(yu)有火(huo)災危險(xian)(xian)的輕危險(xian)(xian)級(ji)(ji)、中(zhong)危險(xian)(xian)級(ji)(ji)、嚴重危險(xian)(xian)級(ji)(ji)的建筑(zhu)物(wu)或構筑(zhu)物(wu)內(nei)，如：車(che)間、倉庫、賓館、商場、娛樂場所、醫院(yuan)、影(ying)劇院(yuan)、辦(ban)公樓及(ji)車(che)庫等場所。該噴(pen)頭(tou)主要由噴(pen)頭(tou)架(jia)、密(mi)封件(jian)及(ji)玻(bo)璃球(qiu)組成。通(tong)過管網安裝于(yu)防(fang)護區(qu)內(nei)，具有探(tan)測(ce)火(huo)災及(ji)自(zi)動(dong)(dong)噴(pen)水(shui)滅火(huo)的作(zuo)(zuo)用(yong)。當防(fang)護區(qu)發生火(huo)災使環境溫度(du)升(sheng)高時，玻(bo)璃球(qiu)內(nei)的液(ye)體受熱膨脹，達到(dao)玻(bo)璃球(qiu)動(dong)(dong)作(zuo)(zuo)溫度(du)后，就會爆破，于(yu)是(shi)密(mi)封件(jian)脫落，噴(pen)頭(tou)開啟(qi)并(bing)按設定的灑(sa)水(shui)形狀噴(pen)向保護區(qu)進行(xing)滅火(huo)。

2、中(zhong)低壓(ya)細(xi)(xi)水(shui)(shui)霧(wu)噴(pen)(pen)(pen)頭(tou)(tou)是由噴(pen)(pen)(pen)頭(tou)(tou)體、噴(pen)(pen)(pen)嘴、分(fen)水(shui)(shui)槽芯及濾網(wang)等(deng)零件(jian)組成，一定(ding)壓(ya)力的水(shui)(shui)通過噴(pen)(pen)(pen)頭(tou)(tou)濾網(wang)進(jin)入噴(pen)(pen)(pen)頭(tou)(tou)后，在分(fen)水(shui)(shui)槽芯內(nei)螺旋、離心霧(wu)化，經混合腔由噴(pen)(pen)(pen)嘴形成的一定(ding)的角度噴(pen)(pen)(pen)霧(wu)而出，該中(zhong)低壓(ya)細(xi)(xi)水(shui)(shui)霧(wu)噴(pen)(pen)(pen)頭(tou)(tou)采用(yong)多只斜向(xiang)離心霧(wu)化小噴(pen)(pen)(pen)嘴組成細(xi)(xi)水(shui)(shui)霧(wu)噴(pen)(pen)(pen)頭(tou)(tou)，與相同流(liu)(liu)量的其(qi)他噴(pen)(pen)(pen)頭(tou)(tou)相比(bi)，在其(qi)覆蓋范圍內(nei)水(shui)(shui)霧(wu)均(jun)勻(yun)性(xing)好(hao)，流(liu)(liu)阻損失(shi)少，從(cong)而使細(xi)(xi)水(shui)(shui)霧(wu)更具有初始動(dong)能和彌(mi)漫(man)性(xing)。
