手動(dòng)盲闆閥(fá)系GB6222《工業(yè)煤氣安(ān)全規程(chéng)》要求的(de)可靠切(qie)🌈斷🥰氣體(tǐ)介🚶‍♀️質🏃🏻‍♂️的(de)設備。它(tā)廣泛适(shi)用于建(jian)材、玻璃(lí)、礦山👈、電(diàn)力、輕工(gōng)👄、造紙等(deng)行業的(de)氣體介(jie)質管路(lù)系統中(zhōng)，特别适(shi)用于有(you)害、有毒(du)、易燃氣(qì)體的切(qie)斷，或做(zuo)管道終(zhong)端盲闆(pǎn)。以縮短(duǎn)檢修時(shí)間或方(fāng)便連接(jie)新的管(guan)路系統(tǒng)。

  This valve is the reliable equipment to cut off gas medium in accord with GB6222 Industry Coal gas Safety Regulation. It is widely used in the pipe system in building material, glass, mining, power, light industry and papermaking departments. It is especially suitable for poison inflammable gas to be cut off or be the terminal blind plate of pipe in order to shorten maintenance time or connect new pipe system. 

結構特(tè)點：

Structure characteristic:

  手動(dòng)盲闆閥(fa)具有結(jie)構新穎(ying)、耐磨損(sun)、密封性(xing)可靠、操(cao)作靈活(huo)💞、安裝方(fang)便、維護(hù)方便、使(shǐ)用壽命(mìng)長等優(yōu)點，帶👣有(yǒu)管道伸(shēn)縮器，能(néng)在切換(huan)閥闆時(shí)不影響(xiǎng)管道設(she)施。特别(bié)适用于(yu)要求快(kuài)速切斷(duàn)及換向(xiàng)的場合(he)。配用旋(xuan)轉連接(jiē)軸螺旋(xuán)副或蝸(wo)輪傳動(dòng)裝置，可(kě)實現啟(qi)閉操作(zuò)，是切換(huàn)密閉的(de)理想設(she)⭕備。

  The valve has the features of compact structure, endurance, reliable seal, flexible operation, easy to maintenance and long life. It can switch valve disc with pipe expansion, which will not affect pipe device. It is suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with rotating connecting axle screw or worm gear driving to form a complete set to realize open-close operation. It is the ideal equipment of switching seal.
