天然氣系統漏氣怎麼辦

天然氣的主要成分是甲烷,相對於煤氣和液化氣,是一種綠色燃料,但也是一種易燃、易爆氣體。因此,使用時要特別小心,首先,要防止天然氣系統漏氣。天然氣系統漏氣原因有多種,主要有以下幾種原因:

  (1)管線上各種接頭填料或墊圈損壞;

  (2)管子被腐蝕有孔眼;

  (3)氣表損壞;

  (4)連接氣管的橡膠軟管老化或損壞,膠管兩端安裝不當;

  (5)灶具旋塞不嚴;

  (6)氣表前閥門填料損壞。

  天然氣漏氣是非常危險的,當聞到有臭雞蛋味或汽油味時表明有漏氣的地方。此時一定要特別小心,不能動火,不能開關電門,不能吸煙或用鐵器相互敲打,不能穿著帶有鐵釘的鞋進入,不能打手機,總之防止一切火花產生。此時應立即打開廚房門窗進行自然通風(注意!此時不可打開排風扇強制通風,以免電機開關和啟動時產生的火花引起天然氣著火),以降低廚房內滲漏的天然氣濃度,同時用肥皂水在可能漏氣的部位進行試驗。試驗地方若產生氣泡,表明此處漏氣,此時應首先關閉進氣閥門。漏氣點無法自行修理時,應立即通知天然氣管理部門進行修理。對天然氣系統檢漏絕不允許使用火柴點火的方法去檢查,這樣做是很危險的,其後果不堪設想。

  為了防止天然氣系統漏氣,平時要好好地維護天然氣設備。家用天然氣各個設備之間的距離均按標準規定的間距進行安裝,不可隨意變動,更不允許用戶私自改動和拆卸。不應在氣管上晾曬濕抹布或衣物,更不應在天然氣管道上和氣表之下懸掛重物,以防止管道受力,造成介面處漏氣。同時也不要把天線或地線接在氣管上,這樣可能產生電火花,易於引起爆炸。天然氣灶具應注意日常維護,發現毛病及時消除,各種開關應輕開輕關,滑動自如,不可強行扭動,防止斷裂。
