意大利ATOS防爆閥,阿托斯防爆閥原理
在火電廠機組運行中,當鍋爐送引風機運行不正常導致爐膛處于過高的引風壓頭下,
同時由于燃料輸入量迅速減少或燃料跳閘,導致爐膛煙氣和壓力急劇降低,
這種惡劣工況的組合將導致爐膛內爆(吸癟),
在鍋爐本體及除塵器前煙道上安裝導磁預緊式防爆閥,
Can make the boiler in the event of explosion can be ahead of the boiler and flue to add air,
To avoid causing permanent deformation of the furnace and flue explosion.
防爆開關閥和防爆比例閥用于有或顆粒出現的易爆環境中
零泄漏電磁閥,板式安裝或螺紋插裝式安裝,
2通閥,錐閥芯:主要用于切斷動力源油路。
目前的插裝式安全閥為“常閉式”,即在電磁鐵得電時打開通流。
Explosion-proof switch valves and explosion-proof
proportional valves are used in explosive atmospheres where there are or particles
Zero leakage solenoid valve, plate mounted or threaded insert type installation,
2-way valve, cone spool: mainly used to cut off the power source oil.
防爆電磁閥工作頻率:動作頻率要求高時,結構應直動式電磁閥,電源應交流
防爆閥一般有兩種形式,水平式防爆閥和垂直式防爆閥。
這兩種防爆閥都是采用防爆膜加蓋的結構形式,
垂直式防爆閥是安裝在筒體上,而水平式防爆閥是安裝在頂部。
The current cartridge safety valve is "normally closed",
that is, when the electromagnet is energized to open the flow.
防爆電磁閥工作制式:分長期工作制,反復短時工作制和短時工作制三種。
防爆電磁閥均為長期工作制,即線圈允許長期通電工作。
對于長時間閥門開通只有短時關閉的情況,
則宜選用常開電磁閥。用在短時工作制而批量又很大時,可作特殊訂貨以降低功耗。
New "X" series of stainless steel direction and pressure control valve,
Mainly used for corrosive environment and special media occasions.
