手動盲(máng)闆閥系gb6222《工業煤(méi)氣安(ān)全規程》要求的(de)可(kě)靠切斷(duàn)氣體介質(zhì)的設備。它(tā)廣泛适用(yòng)于建材、玻璃、礦山、電(diàn)力、輕工、造(zào)紙等行業的氣(qì)體介質管路系(xì)統中，特别(bié)适用(yòng)于有(yǒu)害、有毒、易(yì)燃氣(qì)體的(de)切斷(duàn)，或做(zuò)管道(dào)終端(duān)盲闆。以縮短檢(jiǎn)修時間或(huò)方便連接新的管路(lù)系統。

  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(jié)構特點：

structure characteristic:

  手動(dòng)盲(máng)闆(pǎn)閥具(jù)有結構(gòu)新穎、耐(nài)磨損(sǔn)、密(mì)封性可靠、操作靈(líng)活、安裝方便、維(wéi)護方便、使(shǐ)用壽命長(zhǎng)等優點，帶有管道伸(shēn)縮器，能在(zài)切換閥闆(pǎn)時不影響管道設施(shī)。特(tè)别适(shì)用于要求快速切斷(duàn)及(jí)換向的(de)場(chǎng)合。配(pèi)用旋轉(zhuǎn)連接軸(zhóu)螺旋副或蝸輪傳動裝(zhuāng)置，可實(shí)現啟閉操作，是切換密閉的理想設備。

  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.
