Amanyathelo ofakelo lwevalve yebhabhathane yaseTshayina acacisiweyo: indawo yofakelo, isalathiso kunye nezilumkiso
Ivalve yebhabhathane yaseTshayina sisixhobo sokulawula ulwelo oluqhelekileyo, olusetyenziswa kakhulu kwi-petroleum, ikhemikhali, isinyithi, amandla ombane kunye namanye amashishini kwinkqubo yemibhobho. Ufakelo oluchanekileyo lwe-valve ye-butterfly alukwazi kuphela ukuqinisekisa ukusebenza kwayo okuqhelekileyo, kodwa nokwandisa ubomi bayo benkonzo. Eli nqaku liza kwazisa amanyathelo ofakelo lwevalve yebhabhathane yaseTshayina ngokweenkcukacha ukusuka kwimbono yobuchwephesha.
Okokuqala, misela indawo yokufakwa kwevalve yebhabhathane yaseTshayina. Ivalve yebhabhathane kufuneka ifakwe kumda wecala lombhobho kwaye ube perpendicular kumgca osembindini wombhobho. Ukuba i-valve ye-butterfly yaseTshayina idinga ukufakwa kwisebe lombhobho, qinisekisa ukuba kukho indawo eyaneleyo kumacala omabini ukuququzelela ukuvulwa nokuvalwa kwevalve.
Okwesibini, misela isikhokelo sofakelo lwevalve yebhabhathane yaseTshayina. Indlela yokuhamba kwevalve yebhabhathane kufuneka icace kwaye ihambelane necala lokuhamba kolwelo olukumbhobho. Ukuba icala lokuhamba kwevalve yebhabhathane yaseTshayina alihambelani necala lokuqukuqela kolwelo kumbhobho, kunokubangela ukuba isivalo singasebenzi ngesiqhelo, kwaye sinokubangela nomonakalo kwisixokelelwano sombhobho.
Emva koko, iIvalve yebhabhathane yaseTshayina ifakiwe. Okokuqala, i-valve yebhabhathane yaseTshayina ibekwe kwindawo echazwe kwangaphambili, kwaye i-flange igxininiswe kwi-valve yebhabhathane yaseTshayina. Ngethuba lokufakwa kwenkqubo, kufuneka kuqinisekiswe ukuba i-flange kunye ne-face contact of the pipe ifakwe ngokupheleleyo ukuze kuqinisekiswe ukusebenza kokutywinwa kwe-valve.
Emva koko, qhagamshela intambo yamandla yevalve yebhabhathane yaseTshayina. Xa udibanisa intambo yamandla, qinisekisa ukuba umdibaniso wentambo yamandla ukhuselekile kwaye unokwethenjelwa ukukhusela intambo yamandla ekuweni okanye isiphaluka esifutshane ngexesha lokusebenza.
Ekugqibeleni, iIvalve yebhabhathane yaseTshayina ilungisiwe. Okokuqala, vula amandla, kwaye uvule ngesandla ivalve yebhabhathane yaseTshayina, kwaye ujonge ukuba ivalve inokuvulwa kwaye ivalwe ngempumelelo. Ukuba ivalve ayivuli kwaye ivaleke ngokufanelekileyo, inokufuna ukulungiswa okanye ukufakwa kwakhona.
Xa ufaka iIvalve yebhabhathane yaseTshayina, ezi ngongoma zilandelayo kufuneka ziqatshelwe:
1. Phambi kokufaka iIvalve yebhabhathane yaseTshayina, ingaphakathi lombhobho kufuneka licocwe ukuze kuqinisekiswe ukuba akukho kungcola ngaphakathi kombhobho.
2. Xa ufaka i-valve ye-butterfly yaseShayina, uxinzelelo olugqithisileyo kunye nempembelelo yevalve kufuneka igwenywe.
3. Emva kofakelo lweIvalve yebhabhathane yaseTshayina, i-valve kufuneka igcinwe kwaye ihlolwe ngexesha ukuze kuqinisekiswe ukusebenza kwayo okuqhelekileyo.
Ngokubanzi, ukufakwa ngokuchanekileyo kwevalve yebhabhathane yaseTshayina sisitshixo sokuqinisekisa ukusebenza kwayo okuqhelekileyo. Kuphela ngokulandela amanyathelo achanekileyo kunye neendlela zokufakela sinokuqinisekisa ukusebenza kunye nobomi benkonzo ye-valve ye-butterfly yaseTshayina.
