Imiyalelo yokufakela iivalve zebhola ezinamaphiko Iimfuno zobugcisa zofakelo kunye nokusetyenziswa kweevalvu zegesi engamanzi 1. I-perpendicularity yendawo ye-flange kumbhobho kunye nomgca ophakathi wombhobho kunye nephutha lomngxuma webholithi ye-flange kufuneka ibe phakathi koluhlu oluvunyelweyo. ixabiso. I-valve kunye nomgca wesikhungo sombhobho kufuneka uhambelane phambi kokufakwa. 2. Xa ubophe iibholiti, sebenzisa isitshixo esihambelana ne nut. Xa usebenzisa uxinzelelo lweoli kunye nezixhobo ze-pneumatic zokukhawuleza, qaphela ukuba ungagqithisi i-torque echaziweyo. 3. Xa udibanisa ama-flanges amabini, okokuqala, i-flange yokutywinwa kwendawo kunye ne-gasket kufuneka icinezelwe ngokulinganayo, ukwenzela ukuba kuqinisekiswe ukuba i-flange ixhunyiwe ngoxinzelelo olufanayo lwe-bolt. 4. Ukuqiniswa kwe-flange kufuneka kugweme amandla angalinganiyo, kwaye kufuneka kuqiniswe ngokuhambelana nolwalathiso lwe-symmetry kunye ne-intersection. 5. Emva kokufakwa kwe-flange, qinisekisa ukuba zonke iibholiti kunye namantongomane ziboshwe ngokulinganayo. I-6, ukuqina kweebholiti kunye namantongomane, ukwenzela ukuthintela ukukhulula okubangelwa yi-vibration, ukusebenzisa i-washers. Ukuze ugweme ukunamathela phakathi kweentambo kwiqondo lokushisa eliphezulu, iinxalenye zentambo kufuneka zifakwe kwi-agent echasene ne-adhesion ngexesha lofakelo. 7. Isetyenziselwa iivalvu zobushushu obuphezulu obungaphezulu kwe-300℃. Emva kokuba iqondo lobushushu linyukile, iibholiti zoqhagamshelo lweflange, iibholithi zokuvala ivalve, izitywina zoxinzelelo kunye nokupakisha iibholithi zamadlala kufuneka ziqiniswe kwakhona. I-8, ivalve yeqondo lokushisa eliphantsi lifakwe kwimeko yobushushu bomoya, ngenxa yokwakheka komehluko wobushushu, i-flange, i-gasket, iibholiti kunye namantongomane ayancipha, kwaye ngenxa yokuba izinto zala malungu azifani 9, i-coefficient yokwandiswa komgca kwakhona ezahlukeneyo, ukwenza lula kakhulu ukuvuza iimeko zokusingqongileyo. Ukususela kule meko yenjongo, xa uqinisa iibholithi kwiqondo lokushisa lomoya, i-torque ethatha ingqalelo kwizinto ezinqamlekileyo zecandelo ngalinye kwiqondo lokushisa eliphantsi kufuneka lamkelwe. 1. Ngaphambi kokufakela, i-valve yangaphakathi ye-LPG kufuneka ihlambuluke kwaye iziphene ezibangelwa ukuthutha kufuneka zipheliswe; 2. Ufakelo lwevalve ye-LPG kufuneka igcine i-valve ye-butterfly drive shaft ithe tyaba kunye nevalve yepiston ithe nkqo phezulu; 3. Ngaphambi kokusebenzisa i-valve ye-LPG, isixhobo sokuhambisa kufuneka sihlengahlengiswe ukuze kugcinwe imisebenzi yesixhobo sokuhambisa sichanekile, kwaye ukubetha komda kunye nolawulo lokukhusela ngaphezulu kwe-torque luthembekile; 4. Ioyile yokuthambisa kufuneka yongezwe ngokupheleleyo phambi kokugunyaziswa kunye nokusetyenziswa kwenxalenye nganye yokuthambisa yesixhobo sokuhambisa ivalve yeLPG; 5. Ngaphambi kokuba uqalise isixhobo sombane, incwadana yemigaqo yesixhobo sombane sevalve yegesi enolwelo kufuneka ifundwe ngononophelo.
