Iivalvu zizixhobo eziluncedo ezinceda ukulawula, ukunciphisa, kunye nokuvala ukuhamba kwindlela. Kwinkqubo yokunkcenkceshela kwigadi, ungasebenzisa iivalve ukulawula xa izityalo ezahlukeneyo zinkcenkceshelwa. Ngelixa iivalve ngokuqhelekileyo zibonwa njengoncedo, ukukhetha ivalve efanelekileyo kunokudanisa. Siva ngabathengi abaninzi: “Iintlobo ezininzi kakhulu! Abanye benza into enjalo! Andazi ukuba luhlobo luni lwesivalo emandilusebenzise!”

Sukubanexhala! Kwi-PVC Fittings kwi-Intanethi sibonelela ngazo zonke iintlobo eziphambili zevalvu. Kule posi yebhlog, siza kuchaza into eyenza ukuba nganye ihluke. Kubasebenzisi abasisiseko, eyona nto ibalulekileyo ekufuneka uyikhumbule kukuba ivalve inokwenza enye yezinto ezimbini: ukuvala okanye ukulawula. Ezinye iivalvu zenza nokuba/zombini, kodwa le yindlela elula yokucinga malunga nento ekufuneka yenziwe yivalve. Inokukunceda ukhethe ivalve echanekileyo. Ngoku siza kugubungela uluhlu ngalunye lweevalvu ezinkulu.

Ivalve yebhola
Ivalve yebhola ye-pvc ukukhetha ivalve elungileyo Ivalve yebhola engwevu ngumzekelo omhle wevalve yeglowubhu. Basebenzisa izihlalo ezingqukuva ukumisa okanye ukuvumela ukuhamba. Kukho umngxuma embindini webhola ukuze ulwelo lugqithe xa isiphatho sijikwa kwindawo “ekuyo”. Xa isibambo sijikelezwe ngama-degrees angama-90 kwindawo "yokucima", ulwelo lubetha kwicala eliqinileyo lebhola kwaye liyeke.

Ivalve yebhola ye-PVC emfanekisweni iye yachithwa ukuze ukwazi ukubona ukusebenza kwayo kwangaphakathi. Lo usebenzisa irabha O-ring ukuqinisekisa itywina. Iivalvu zebhola zizivalvu zeglowubhu ngenxa yokuba ngokuqhelekileyo aziyilwanga ukuba zivuleke ngokuyinxenye. Bathetha ukuvula ngokupheleleyo okanye ukuvalwa ngokupheleleyo. Ngokuxhomekeke kuhlobo lwevalve yebhola oyithengayo, banokufumana ukuhla koxinzelelo. Oku kungenxa yokuba ububanzi bomngxuma kwibhola yevalve ngokuqhelekileyo buncinci kunobubanzi bombhobho ngokwawo.

Ivalve yebhabhathane
Ukukhetha ivalve yebhabhathane echanekileyo inokudlala indima yevalve yeglowubhu okanye ivalve elawulayo. Ziyakwazi ukuvala ngokupheleleyo ukuhamba okanye zihlale zivulekile, ngaloo ndlela zithintele ukuhamba. Ukulawula ukuhamba kuluncedo ukuba ufuna ukunciphisa uxinzelelo kwindlela yakho. Ukuhamba ngembobo encinci kuya kuthintelwa, ukunciphisa uxinzelelo phantsi kombhobho, kuxhomekeke kwindlela evulekile ngayo i-valve. Iivalvu zebhabhathane nazo zisenokusetyenziswa njengeevalvu ezijikelezayo ze-90 degree ngokutshintsha ngokulula phakathi kweendawo "zokuvula" kunye "nokucima".

Izivalo zebhabhathane zisebenzisa idiskhi ejikeleza isikhondo esisembindini ukulawula ukudlula kolwelo. Ivalve yebhabhathane yePVC eboniswe inesiphatho esimisa sitshixe naphi na phakathi kokuvula ngokupheleleyo okanye ukuvalwa. Oku kuvumela ulawulo oluchanekileyo. Eyona nto ibalulekileyo ekufuneka uyiqaphele xa usebenzisa izivalo zebhabhathane kukuba zifuna iiflange ezikhwelayo. Awunakuvele udibanise nabo kwimibhobho. Oku kwenza ukufakela kube nzima ngakumbi, kodwa akunakwenzeka! Olunye uphawu olubalulekileyo lweevalvu zebhabhathane kukuba kukho ukuhla koxinzelelo lwendalo ngenxa yokuba idiski ihlala ihamba.

Isango

Ivalve yesango elingwevu elinesibambo esibomvu pvcGate, nangona iqhele ukusetyenziswa njengevalve yokuvala, ingasetyenziswa njengevalve elawulayo. Basebenzisa ukuhla okanye ukunyuka "amasango" ukulawula ukuhamba. Xa i-valve ivuliwe, isango ligcinwa kwindawo ephezulu ephezulu yevalve, apho i-valve yesango ifumana imo ekhethekileyo. Ngokungafaniyo neevalve ezimbini zokuqala, i-valve yesango ayikho i-valve yekota yokujika. Basebenzisa ivili lesandla ukuvula/ukuvala, ngelixa iivalve zebhola kunye nebhabhathane zisebenzisa i-lever handle. Oku kuzenza kube lula ukuzigcina zivulekile kwaye kwenza naluphi na uhlobo lokukhohlisa lula.

Enye indlela yokusebenzisa ivalve yesango kulawulo lokuhamba kukuba ulwelo luya kubetha umphezulu wesango elisicaba. Ngokuxhomekeke kubungakanani boxinzelelo kwinkqubo, oku kunokubangela ukugqoka ngexesha. Ivalve yesango efanekiselwayo luyilo lomanyano lokwenyani, nto leyo ethetha ukuba inokuqhaqhwa ngokulula. Oku kulungele ukucoca, ukugcinwa kunye nokulungiswa. Iivalve zesango azifuni iiflange; zinokufakwa ngokuthe ngqo kumbhobho.

Jonga ivalve
Iivalvu ze-pvc ezibonisa ujingi wokukhangela i-valve blueCheck ziyafumaneka ngeendlela ezininzi. Umsebenzi oyintloko wevalve yokutshekisha kukuthintela umva. Oku kuzenza zilawule iivalvu kuba zilawula icala lokuhamba. Iivalvu zokukhangela zilawulwa lulwelo emgceni kunokuba umsebenzisi, nto leyo ezenza zahluke kwiivalvu esikhe sizivavanye ngaphambili. Iivalvu zokukhangela ziza ngeendlela ezininzi ezahlukeneyo, kodwa siza kugquma kuphela ezona ndidi ziqhelekileyo zimbini.

Ivalve yokukhangela i-swing yivalve esebenzisa umsebenzi we-swing ukuthintela ukubuyela umva kwinkqubo. Ivalve ecacileyo yokujonga ujingi wePVC ngasekunene inediski ekhululayo ukuba ulwelo ludlula kwicala elifunekayo. Ukuba kukho nantoni na ezama ukubuyisela umva ukuhamba, i-disc ityhilwa ivaliwe, imise ukuhamba. Iivalvu zokujonga ujingi zivelisa ukwehla koxinzelelo oluncinci kuba idiski ityhilwe ivuleke ngokupheleleyo ngexesha lokusebenza.
