Ukushisa Kwesifunda Okushiselwe Ngokugcwele I-Ball Valve
Imininingwane Yomkhiqizo
I-valve yebhola yesifunda eshiselwe ngokugcwele yokushisa emadolobheni inezici zokuvalwa ngokuqinile, akukho ukuvuza, ukwethembeka okuphezulu kanye nempilo ende yesevisi, esetshenziswa kabanzi emapayipini amanzi ashisayo angcwatshwe ngokuqondile.Ngenxa yokuthi impahla yomzimba we-valve iyafana nempahla yepayipi, ngeke kube nengcindezi engalingani, futhi akukho ukuguquguquka ngenxa yokuzamazama komhlaba nezimoto ezidlula emhlabathini, futhi ipayipi liyamelana nokuguga.
Njengeyunithi eyisikiwe evulekile/evaliwe, umzimba uyisakhiwo esishiselwe ngokuphelele esakhiwe ngepayipi lensimbi ecindezelwe noma ipuleti.Inezakhiwo ezintantayo nezifakwe nge-trunnion, isakhiwo sesihlalo se-valve sinomphumela we-piston futhi sinxephezela umklamo.Isakhiwo sophawu senzelwe uphawu olulodwa noma uphawu oluphindwe kabili (indandatho ehlezi ethambile nensimbi ihlezi), intwasahlobo izoqinisekisa ukucindezela kwendandatho yophawu ebholeni, futhi i-valve isengakwazi ukuhlala ingavuzi ngokuqinile futhi isebenze ukusebenza okuzinzile isikhathi eside noma ngabe ingcindezi ayizinzile.I-valve yebhola inezinzuzo zevolumu encane, isisindo esincane, ukufaka uphawu ngaphandle kokuvuza, ukugcinwa kwamahhala, impilo ende yesevisi, ukusebenza okulula nokunye.
Izimpawu Zokusebenza
1.Full bore futhi Nciphisa ukwakheka kwebhore;
2.Kulula futhi kuyashesha vula futhi uvale
Lolu hlobo lwe-valve yebhola ludinga kuphela ukuzungezisa ibhola (isici esivulekile/ sokuvala) 90°, okulula futhi esisheshayo ukusebenza.
3.Good seal ukusebenza
Isihlalo se-valve yebhola eshiselwe ngokugcwele ngokuvamile senziwe ngezinto ezinwebekayo njenge-PTFE, njll., ngokuvaleka kwebhola lensimbi, ngokuvamile kubizwa ngokuthi kuhlezi okuthambile okungaqinisekisa kalula ukusebenza kophawu.
4.Umzimba we-valve wenziwe ngepayipi lensimbi engenamthungo noma wenziwe ngesakhiwo se-welding esakhiwe sepuleti eligoqayo;
5.Umjikelezo wempilo ende
Ngenxa ye-self-lubrication ye-PTFE enhle, ukungqubuzana nokugqoka ngebhola kuncane, futhi ukuhlukumeza kuncishiswa ukuthuthukiswa kwenqubo yokucubungula i-valve yebhola, ukuze impilo yesevisi ye-valve yebhola inwetshiwe.
6.Ukuthembeka okuphezulu
I-valve yebhola eshiselwe ngokugcwele inokwethenjelwa okuphezulu, ikakhulukazi ngoba:
a) isihlalo sevalvu se-PTFE impahla sinokuzithambisa okuhle, ukungqubuzana okuncane nokugqokwa nebhola, akukho ukuhuzuka nokugqokwa okubukhali;
b)Isiqu sifakwe ngaphakathi, ngaleyo ndlela sizogwema ingozi engenzeka ngenxa yokuphephuka kwesiqu ngenxa yokuxega okungenzeka kwegland epakishayo ngaphansi kokucindezela koketshezi.
7.Ukunqanda ukuqhunyiswa kwesiqu, ukuvaleka kwesiqu ngezingqimba eziningana;
8.Ibhola linezinhlobo ezimbili ze-trunnion efakwe futhi entantayo;
9.Isihlalo se-valve esiphindwe kabili, ungqimba olulodwa noma indandatho yophawu oluthambile oluphindwe kabili kanye nensimbi yokuvala uphawu kwensimbi yakha izimpawu ezinezingqimba eziningana;
10.Ukuzikhulula kwe-cavity ngaphansi kwengcindezi ngokweqile;
11.Isakhiwo esiphindwe kabili kanye negazi (DBB)(Uma kudingeka);
12.I-Flexible evulekile / evaliwe, kulula ukuyisebenzisa.
13.Maintenance free
Le valve yebhola inesici sokulungisa mahhala.
Okumaphakathi Okusebenzayo
Ifanele kakhulu igesi yemvelo, amanzi ashisayo
Isakhiwo
Umfanekiso wesakhiwo kanjena
Lolu hlobo lwe-valve yebhola ikakhulukazi luqukethe umzimba, i-adaptha, ibhola, isiqu, isihlalo sendandatho yophawu, i-actuator, njll.
