Kukho umahluko omkhulu phakathiiivalvu zokujongakunye neevalvu zokunceda kwiinkalo ezininzi, ezibonakala kakhulu kumsebenzi wazo, ulwakhiwo, umgaqo wokusebenza kunye neemeko zokusetyenziswa kwazo. Nantsi inkcazelo engezantsi:
Umahluko osebenzayo
Ivalvu yokujonga: Umsebenzi ophambili kukuthintela i-media ukuba ingabuyeli emva kwipayipi. Ivumela i-media ukuba ihambe ngokukhululekileyo kwicala elinye, kodwa xa i-media ingena ngasemva, i-check valve iya kuvala ngokuzenzekelayo ukuthintela i-media backflow ukuba ingonakalisi inkqubo. I-check valve ikwadlala indima ebalulekileyo ekuthinteleni ipompo kunye ne-drive motor yayo ekujikeni nasekuthinteleni i-media ekwisikhongozeli ekuvuzeni.
Ivalvu yokunceda: Umsebenzi ophambili kukuthintela uxinzelelo kwinkqubo okanye kwizixhobo ukuba ludlule ixabiso elichaziweyo. Xa uxinzelelo ludlula ixabiso elibekiweyo, ivalvu yokhuseleko iya kuvula ngokuzenzekelayo ize ikhulule inxalenye yesixhobo ukuze kuncitshiswe uxinzelelo, ngaloo ndlela ikhusele ukhuseleko lwezixhobo kunye nenkqubo. Ivalvu yokhuseleko sisixhobo esibalulekileyo sokukhusela izixhobo kunye nabasebenzi kuxinzelelo olugqithisileyo.
Umahluko kwisakhiwo
Ivalvu yokujonga:Isakhiwo silula, sidla ngokuba ngumzimba, isigqubuthelo sevalvu, intwasahlobo yevalvu kunye nesihlalo kunye nezinye iindawo. Umgaqo wayo wokusebenza uxhomekeke kakhulu kumandla aveliswa kukuhamba kwesixhobo ukuvula nokuvala ivalvu.
Ivalvu yokhuseleko:Isakhiwo siyinkimbinkimbi, sidla ngokuba ngumzimba wevalvu, intwasahlobo, iziqwenga, iindawo ezikhokelayo kunye nezinye iindawo. Ezi nxalenye zisebenza kunye ukuqinisekisa ukuba ivalvu yokhuseleko ivuleka kwaye ivale ngokuchanekileyo xa uxinzelelo olubekiweyo lufikelelwa. Uyilo lwesakhiwo sevalvu yokhuseleko kufuneka luqwalasele uxinzelelo, ubushushu, ukuhamba kunye nezinye izinto zesixhobo.
Umahluko kumgaqo wokusebenza
Ivalvu yokujonga: Umgaqo wokusebenza usekelwe kumandla aveliswa kukuhamba kwe-medium. Xa i-medium isiya phambili kumbhobho, amandla aveliswa yi-medium atyhala idiski yevalvu yokujonga ivuleke aze avumele i-medium ukuba idlule. Xa i-medium isiya ngasemva, idiski yevalvu iya kusetyenziswa isenzo esidibeneyo se-medium kunye nentwasahlobo yevalvu ukuvala ivalvu, ngaloo ndlela ithintela i-medium ukuba ibuyele umva.
Ivalvu yokhuseleko: Umgaqo wokusebenza usekelwe kulawulo loxinzelelo. Xa uxinzelelo olukwinkqubo okanye kwizixhobo ludlula ixabiso elimiselweyo, intwasahlobo yevalvu yokhuseleko iyacinezelwa ukuya kuthi ga kwinqanaba elithile, kwaye ivalvu iya kuvula kwaye ikhulule inxalenye yesixhobo ukuze kuncitshiswe uxinzelelo. Xa uxinzelelo luhla ngaphantsi kwexabiso elimiselweyo, intwasahlobo ibuyela kwindawo yayo ize ivale ivalvu.
Umahluko phakathi kweemeko zesicelo
Ivalvu yokujonga: isetyenziswa kakhulu kwiikhemikhali, ipetroliyam kunye neminye imimandla yemizi-mveliso yenkqubo yemibhobho. Isetyenziswa kakhulu ukuthintela umonakalo kwinkqubo obangelwa kukubuyela umva kwemidiya, njengokuthintela ipompo kunye nemoto yayo yokuqhuba ukuba ingabuyeli umva, ukuthintela imidiya ekwisikhongozeli ukuba ingavuzi.
Ivalvu yokhuseleko: ikwasetyenziswa kakhulu kwiikhemikhali, umbane, ipetroli, isinyithi kunye neminye imimandla yezixhobo okanye izakhiwo. Ingakumbi kwiibhoyila, imikhumbi yoxinzelelo, imibhobho kunye nezinye iinkqubo, iivalvu zokhuseleko zizixhobo ezibalulekileyo zokukhusela izixhobo ukuba zonakaliswe ngenxa yoxinzelelo oluphezulu.
Isishwankathelo
Kukho umahluko omkhulu phakathiiivalvu zokujongakunye neevalvu zokhuseleko ngokwemisebenzi, ulwakhiwo, umgaqo wokusebenza kunye neemeko zokusetyenziswa. Kwizicelo ezisebenzayo, iintlobo zeevalvu ezifanelekileyo kufuneka zikhethwe ngokweemfuno ezithile kunye neemeko ukuqinisekisa ukusebenza okuqhelekileyo kunye nokhuseleko lwezixhobo kunye neenkqubo.
