Sprengisvörn-tengibox er sprengivörn-vara fyrir raflögn sem notuð eru í sérstöku hættulegu umhverfi. Það eru tengiblokkir í sprengivörnum-tengiboxinu. Sprengingar-einkunnir tengiboxum er skipt í IIB einkunn og IIC einkunn í samræmi við sprengi-einkunn. Sprengiþolnir-tengingarkassa er almennt skipt í beint-í gegnum, teig, kross, horn o.s.frv. í samræmi við fjölda hausa; ef þeir eru flokkaðir í samræmi við útlit efstu hlífarinnar, er sprengi-þétti tengiboxum skipt í Það eru tvær tegundir af sprengi-þéttum tengiboxum með flatri hlíf og sprengi- tengibox með hangandi loki.
Sprengi-þéttir tengiboxar eru notaðir á sprengivörnum-svæðum, aðallega fyrir hús, grindvirki og þegar snúrur breyta um stefnu. Sprengi-tengiboxið er notað til að tengja leiðsluna og sveigjanlega rörið er notað fyrir tengingu milli leiðslunnar og yfirborðsins. Þegar sprengivörn tengiboxið er tengt við staðbundið yfirborð eins og hitaeiningu, hitauppstreymi, sendi o.s.frv., ætti að nota málmslöngu eða sveigjanlega tengingu sem verndarrör. Beygja -sprengiþétta tengiboxsins er yfirleitt úr olnbogum. Þegar hver tveir 90 gráðu olnbogar eða beinlínulengd snittipípunnar fer yfir 30m, ætti að setja upp sprengivörn tengibox.
In fact, many customers can't tell the difference between explosion-proof junction boxes, explosion-proof threading boxes, and explosion-proof junction boxes. The editor of explosion-proof junction box manufacturers is here to explain the role of explosion-proof junction boxes for us: Explosion-proof junction boxes, explosion-proof threading boxes There are also explosion-proof junction boxes that are used for the interface of the line when connecting the wires during decoration, but the three have their own uses. Let me talk about the differences in the use of the three. 1, the role of explosion-proof junction box; explosion-proof junction box is used to connect the nanowires and equipment or devices, as well as the transition between light and dark pipelines and the transition between rigidity and flexibility. 2. The role of the explosion-proof junction box; the explosion-proof threading box is when the laying length of the line pipeline exceeds a certain limit, perhaps the line is divergent, or the line has too many bends, when the whole pipe is not easy to thread, this is at the base You need to add a box, this box is the explosion-proof junction box. 3. The role of the explosion-proof junction box; the explosion-proof junction box is the place where power distribution, electrical equipment and external lines are connected. This place needs a device to protect the line, and a box will be added in this place for protection. There are generally limited terminal blocks in the interior, or there may be no terminals but there are connection ends of switching devices. Under normal circumstances, this connection device can be disassembled.
