Kunezinhlobo eziningi nezinhlobo eziyinkimbinkimbi zeama-valve, ikakhulukazi kufaka phakathi ama-valve esango, ama-globe valves, ama-throttle valves, ama-butterfly valves, amapulaki ama-valve, ama-valve amabhola, ama-valve kagesi, ama-diaphragm valve, ama-valve okuhlola, ama-valve okuphepha, ama-valve okunciphisa ukucindezela, izicupho zesitimu kanye nama-valve okuvala okuphuthumayo, njll. zivame ukusetshenziswa isango valve, globe valve, mpintsha valve, ipulaki valve, uvemvane valve, ibhola valve, isheke valve, diaphragm valve.
1 Butterfly valve
I-Butterfly valve umsebenzi wokuvula nowokuvala wepuleti uvemvane ungaqedwa ngokuzungezisa u-90° ekseni egxilile emzimbeni wevalvu.I-Butterfly valve incane ngosayizi, ilula ngesisindo futhi ilula ngesakhiwo, futhi iqukethe izingxenye ezimbalwa kuphela.Futhi idinga kuphela ukushintshanisa i-90 °;ingavulwa futhi ivalwe ngokushesha, futhi ukusebenza kulula.Lapho i-valve uvemvane isendaweni evuleke ngokugcwele, ukushuba kwepuleti uvemvane kuwukuphela kokumelana lapho okuphakathi kugeleza emzimbeni we-valve, ngakho-ke ukwehla kokucindezela okukhiqizwa i-valve kuncane kakhulu, ngakho kunezici zokulawula ukugeleza okungcono.I-valve ye-butterfly ihlukaniswe yaba yi-elastic soft seal kanye ne-metal hard seal.I-valve yokuvala enwebekayo, indandatho yokuvala ingafakwa emzimbeni we-valve noma ixhunywe endaweni ezungezile yediski, ngokusebenza kahle kokuvala, okungase isetshenziselwe ukudonsa, amapayipi evacuum aphakathi nendawo kanye nemidiya ebolayo.Amavalvu anezigxivizo zensimbi ngokuvamile aphila isikhathi eside kunalawo anezigxivizo ezinwebekayo, kodwa kunzima ukufeza ukuvalwa okuphelele.Ngokuvamile zisetshenziswa ezikhathini ezinezinguquko ezinkulu ekugelezeni nasekunciphiseni ingcindezi futhi ezidinga ukusebenza kahle kokudonsa kanzima.Izigxivizo zensimbi zingakwazi ukuzivumelanisa nezinga lokushisa eliphakeme lokusebenza, kuyilapho izigxivizo ezinwebekayo zinesici sokunqunyelwa izinga lokushisa.
2I-valve yesango
Ivalvu yesango isho ivalvu umzimba wayo wokuvula nokuvala (i-valve plate) ishayelwa isiqu se-valve futhi yehla inyuka ihambisana nendawo yokuvala yesihlalo sevalvu, engaxhuma noma inqamule uketshezi oludlulayo.Uma kuqhathaniswa ne-globe valve, i-valve yesango inokusebenza okungcono kokuvala, ukumelana noketshezi oluncane, umzamo omncane wokuvula nokuvala, futhi inokusebenza okuthile kokulungisa.Ingenye yama-block valves asetshenziswa kakhulu.Okubi ukuthi ubukhulu bukhulu, isakhiwo siyinkimbinkimbi kakhulu kune-valve yembulunga, indawo yokubeka uphawu kulula ukuyigqoka, futhi akulula ukuyigcina.Ngokuvamile, ayifaneleki ukudonsa.Ngokusho kokuma kwentambo esiqwini se-valve yesango, ihlukaniswe yaba izinhlobo ezimbili: uhlobo lwenduku evulekile kanye nohlobo lwenduku emnyama.Ngokwezici zesakhiwo sesango, lingahlukaniswa ngezinhlobo ezimbili: uhlobo lwe-wedge kanye nohlobo oluhambisanayo.
3 Hlola i-valve
I-valve yokuhlola iyi-valve engavimbela ngokuzenzakalelayo ukugeleza koketshezi.I-valve flap ye-valve yokuhlola ivuliwe ngaphansi kwesenzo sokucindezela kwamanzi, futhi uketshezi lugeleza lusuka ohlangothini lokungena luye ohlangothini lokuphuma.Uma ingcindezi ohlangothini lokungena iphansi kunaleyo ehlangothini lokuphuma, i-valve flap izovala ngokuzenzakalelayo ngaphansi kwesenzo somehluko we-fluid pressure, amandla ayo adonsela phansi kanye nezinye izici zokuvimbela uketshezi ukuthi lungagelezi emuva.Ngokwesakhiwo, ingahlukaniswa i-valve yokuhlola i-lift kanye ne-swing check valve.Uhlobo lokuphakamisa lunokusebenza okungcono kokuvala nokumelana noketshezi okukhudlwana kunohlobo lokushwiba.Ngembobo yokudonsa yepayipi lokudonsa lepompo, i-valve engezansi kufanele ikhethwe.Umsebenzi wayo ukugcwalisa ipayipi lokungena lepompo ngamanzi ngaphambi kokuqala iphampu;gcina ipayipi lokungena kanye nomzimba wephampu ugcwaliswe ngamanzi ngemva kokumiswa kwepompo, ukuze ulungiselele ukuqala kabusha futhi.Ivalvu engezansi ivamise ukufakwa kuphela epayipini eliqondile lendawo yokungena yepompo, kanti ephakathi igeleza ukusuka phansi ukuya phezulu.
4 I-valve yomhlaba
Ivalvu yembulunga iyivalvu evalekile eyehlayo, futhi ilungu elivulayo nelivalayo (ivalvu) lishayelwa isiqu sevalvu ukuze siye phezulu naphansi eduze kwe-eksisi yesihlalo sevalvu (indawo yokuvala).Uma kuqhathaniswa ne-valve yesango, inokusebenza okuhle kokulungisa, ukusebenza kahle kokuvala uphawu, isakhiwo esilula, ukwakhiwa nokugcinwa okulula, ukumelana noketshezi olukhulu kanye nenani eliphansi.
5 I-valve yebhola
Ingxenye evulayo nevalayo ye-valve yebhola iyindilinga enembobo eyisiyingi, futhi i-sphere izungeza nesiqu se-valve ukuze ibone ukuvuleka nokuvalwa kwevalvu.I-valve yebhola inesakhiwo esilula, ukushintsha okusheshayo, ukusebenza okulula, usayizi omncane, isisindo esilula, izingxenye ezimbalwa, ukumelana noketshezi oluncane, ukusebenza kahle kokuvala uphawu nokugcinwa okulula.
6 I-valve ye-throttle
Ukwakheka kwe-throttle valve ngokuyisisekelo kuyafana naleyo ye-globe valve ngaphandle kwe-valve disc.I-valve disc iyingxenye ye-throttling, futhi izimo ezihlukene zinezici ezihlukene.Ububanzi besihlalo se-valve akufanele bube bukhulu kakhulu, ngoba ukuphakama kokuvula kuncane.Izinga lokugeleza okuphakathi liyakhula, ngakho-ke Isheshisa ukuguguleka kwediski ye-valve.I-valve ye-throttle inezilinganiso ezincane, isisindo esilula nokusebenza okuhle kokulungisa, kodwa ukunemba kokulungiswa akuphakeme.
7 I-valve yokuxhuma
I-valve yepulaki isebenzisa umzimba wepulaki onembobo ephumela njengengxenye yokuvula neyokuvala, futhi umzimba wepulaki uzungeza nesiqu se-valve ukubona ukuvuleka nokuvala kwevalvu.I-valve yepulaki inezinzuzo zesakhiwo esilula, ukushintsha okusheshayo, ukusebenza okulula, ukumelana noketshezi oluncane, izingxenye ezimbalwa nesisindo esincane.Kunama-valve amapulaki aqondile, anezindlela ezintathu kanye nanezindlela ezine.I-valve yepulaki eqondile isetshenziselwa ukusika i-medium, futhi ama-valve amapulaki anezindlela ezintathu nezine asetshenziselwa ukushintsha isiqondiso se-medium noma ukuhlukanisa okuphakathi.
8 I-valve ye-diaphragm
Ingxenye evulayo nevalayo ye-valve ye-diaphragm iyi-diaphragm yerabha, ehlanganiswe phakathi komzimba we-valve kanye nesembozo se-valve.Ingxenye ephakathi nendawo ephumayo ye-diaphragm igxilile esiqwini se-valve, futhi umzimba we-valve ufakwe irabha.Njengoba i-medium ingangeni emgodini wangaphakathi wekhava ye-valve, isiqu se-valve asidingi ibhokisi lokugxusha.I-valve ye-diaphragm inesakhiwo esilula, ukusebenza kahle kokuvala, ukugcinwa okulula nokumelana noketshezi oluncane.Amavalvu e-diaphragm ahlukaniswe ngohlobo lwe-weir, uhlobo oluqondile, uhlobo lwe-engeli yesokudla kanye nohlobo lokugeleza okuqondile.
