Izinyathelo zokufaka uvemvane lwe-Chinese zinemininingwane: indawo yokufaka, isiqondiso nezinyathelo zokuphepha
I-valve yevemvane yaseChina iyithuluzi elivamile lokulawula uketshezi, elisetshenziswa kabanzi ku-petroleum, amakhemikhali, i-metallurgy, amandla kagesi nezinye izimboni ohlelweni lwamapayipi. Ukufakwa okulungile kwe-valve ye-butterfly akukwazi nje ukuqinisekisa ukusebenza kwayo okujwayelekile, kodwa futhi kwandise impilo yayo yesevisi. Lesi sihloko sizokwethula izinyathelo zokufakwa kwe-valve uvemvane wase-Chinese ngokuningiliziwe ngokubuka kochwepheshe.
Okokuqala, thola indawo yokufaka i-valve butterfly yaseShayina. I-valve uvemvane kufanele ifakwe ohlangothini lobubanzi bepayipi futhi ibe yi-perpendicular emgqeni ophakathi wepayipi. Uma i-valve ye-butterfly yaseShayina idinga ukufakwa egatsheni lepayipi, qinisekisa ukuthi kunesikhala esanele ezinhlangothini zombili ukuze kube lula ukuvula nokuvalwa kwe-valve.
Okwesibili, thola isiqondiso sokufakwa kwe-valve butterfly yaseShayina. Indlela yokugeleza kwevalve uvemvane kufanele icace futhi ihambisane nesiqondiso sokugeleza koketshezi epayipini. Uma isiqondiso sokugeleza kwe-valve uvemvane lwase-China ingahambisani nesiqondiso sokugeleza koketshezi epayipini, kungase kubangele ukuthi i-valve ingasebenzi ngendlela evamile, futhi ingase ibangele nomonakalo ohlelweni lwamapayipi.
Bese, theI-valve ye-butterfly yaseShayina ifakiwe. Okokuqala, i-valve ye-butterfly yaseShayina ibekwe endaweni enqunywe kusengaphambili, bese i-flange igxilwe ku-valve butterfly yaseShayina. Phakathi nenqubo yokufaka, kufanele kuqinisekiswe ukuthi i-flange kanye nendawo yokuxhumana yepayipi ifakwe ngokugcwele ukuze kuqinisekiswe ukusebenza kokuvala kwe-valve.
Okulandelayo, xhuma intambo yamandla yevalve uvemvane lwaseShayina. Uma uxhuma ikhebula lamandla, qinisekisa ukuthi isixhumi sekhebula lamandla sivikelekile futhi sithembekile ukuze uvimbele ikhebula lamandla ukuthi lingawi noma lifinyeze ngesikhathi sokusebenza.
Ekugcineni, iI-valve ye-butterfly yaseShayina isuswe iphutha. Okokuqala, vula amandla, bese uvula ngesandla i-valve butterfly yaseShayina, bese ubheka ukuthi i-valve ingavulwa futhi ivalwe ngempumelelo. Uma i-valve ingavuli futhi ivaleke kahle, kungase kudingeke ukuthi ilungiswe noma ifakwe kabusha.
Lapho ufaka i-I-valve ye-butterfly yaseShayina, amaphuzu alandelayo kufanele futhi aqashelwe:
1. Ngaphambi kokufaka i-I-valve ye-butterfly yaseShayina, ingaphakathi lepayipi kufanele lihlanzwe ukuze kuqinisekiswe ukuthi akukho ukungcola ngaphakathi kwepayipi.
2. Uma ufaka i-valve ye-butterfly yaseShayina, ukucindezela ngokweqile kanye nomthelela we-valve kufanele kugwenywe.
3. Ngemva kokufakwa kwe-I-valve ye-butterfly yaseShayina, i-valve kufanele igcinwe futhi ihlolwe ngesikhathi ukuze kuqinisekiswe ukusebenza kwayo okuvamile.
Ngokuvamile, ukufakwa okulungile kwe-valve ye-butterfly yaseShayina kuyisihluthulelo sokuqinisekisa ukusebenza kwayo okuvamile. Kuphela ngokulandela izinyathelo ezifanele nezindlela zokufaka singaqinisekisa ukusebenza kanye nempilo yesevisi ye-valve uvemvane lwaseShayina.
