德國奇冠彈簧式呼吸閥(QIGHXF-I型)
主要用途:
根據標準《石油化工企業設計防火規范》(GB50160-90)之規定,“甲、乙類液體的固定頂罐,應用阻火器和呼吸閥“。可見呼吸閥,阻火器是儲罐*的安全設施,它不僅能維持儲罐氣壓平衡,確保儲罐在超壓或真空時免遭破壞,且能減少罐內介質的揮發和損耗,呼吸閥是維護儲罐氣壓平衡,減少介質揮發的安全節能產品,常與阻火器配套使用。
Main purposes:
According to the national standard "for fire protection design of petrochemical enterprises" (GB50160-90) regulations, "A and B liquid fixed roof tank, flame arrester and the breathing valve applications." Visible breathing valve, flame arrester is indispensable safety tank, it can not only maintain the pressure balance tank, to ensure that excess pressure or vacuum in the tank when the acts of vandalism, and can reduce evaporation and loss of the medium tank, breathing valve tank pressure is to maintain balance, reduce the security of energy-saving products volatile media, often with supporting the use of flame arresters.
主要特點:
QIG公司生產的呼吸閥,具有結構緊湊,通氣量大,泄漏量小,耐腐蝕,密封性能好等特點,zui近又開發具有*水準的防暴阻火呼吸閥(KHXF-IZ型),阻火器位于呼吸閥吸入口處,*杜絕火源進入呼吸閥殼體內,具有體積小,重量輕,檢修,清洗,更換方便等優點。閥盤采用聚四氟乙烯材料,具有耐低溫,防凍等優點。閥內設靜電輸出裝置,使得該閥時刻與罐體保持等電位。
Main features:
QIG produced the breathing valve, with a compact, ventilation volume, leakage and corrosion, good sealing performance characteristics, recently developed the international advanced level of anti-riot Fire breathing valve (KHXF-IZ-type), flame arrester Respiratory suction valve is located at the entrance, the complete elimination of the fire source into the breathing valve shell, small size, light weight, maintenance, cleaning, replacement and easy. Valve plate with PTFE material with low temperature, freezing and so on. Valve equipped with static output devices, which makes the valve and the tank to keep other potential times.

維護保養方法:
1、 存放:
呼吸閥產品在運達工地后,若暫時不安裝或以后工廠大修、檢修,應存放在有防雨設施的倉庫中:呼吸閥系列產品在運輸時不得倒置。
2、 維護:
a、 呼吸閥系列產品,應每月上罐頂檢查一次,檢查閥盤、閥座、閥桿、閥套等部位是否有灰塵、污垢,若有,應清理干凈:每半年給閥套、閥桿擦拭一遍變壓器油。
b、 每半年應檢查阻火器呼吸閥的阻火層一次,若發現有污漬、雜質堵塞阻火層,應取下阻火層,用相對應的溶劑清楚污漬,然后用清水將阻火層清洗干凈,放在通風吹干后再放入殼體內。
c、 以上產品殼體內外表面的油漆應每年涂刷一遍。
訂貨須知:
