style="text-indent:25px">隨著國民經(jīng)濟(jì)的持續(xù)發(fā)展,本市到處可見外形美觀、風(fēng)格迥異的高層、超高層建筑。在這些建筑物內(nèi),設(shè)計(jì)師和建設(shè)者為了提高有效益的使用面積,往往采取將食堂或餐廳等放在地下室的辦法。此外,隨著我國城市煤氣事業(yè)的蓬勃發(fā)展,煤氣的供應(yīng)能力**提高,這就使得大樓**空調(diào)采用煤氣直燃式冷暖機(jī)組成為現(xiàn)實(shí),而該空調(diào)機(jī)組也大多置于地下室。尤其在地下室,若遇煤氣泄漏,則由于建筑上和通風(fēng)上的限制,而更有其危害性。然而,如果設(shè)置一套煤氣泄漏緊急自動(dòng)切斷系統(tǒng),則遇到各種原因引起煤氣泄漏時(shí),可以及時(shí)關(guān)閉煤氣切斷閥,防止因煤氣泄漏而引起的各種事故。煤氣探頭探頭不但設(shè)置在灶具前,也應(yīng)設(shè)置在煤氣管道的經(jīng)過處。這樣,不但灶具上的煤氣漏泄可以探測到,而且煤氣管道經(jīng)過處煤氣的漏泄也可探測到。從而可保證整個(gè)系統(tǒng)的安全。探頭有多種型式,可選用適宜于城市煤氣的型式。</p><p
