Isingeniso sama-valve avamile

Kunezinhlobo eziningi nezinhlobo eziyinkimbinkimbi zeamavalvu, ikakhulukazi okuhlanganisa ama-valve esango, ama-valve embulunga, ama-valve e-throttle, ama-valve e-butterfly, ama-valve e-plug, ama-valve ebhola, ama-valve kagesi, ama-valve e-diaphragm, ama-valve okuhlola, ama-valve okuphepha, ama-valve okunciphisa ingcindezi, izicupho zomusi kanye nama-valve okuvala okuphuthumayo, njll., avame ukusetshenziswa njenge-valve yesango, i-valve yembulunga, i-valve ye-throttle, i-valve ye-plug, i-valve ye-butterfly, i-valve yebhola, i-valve yokuhlola, i-valve ye-diaphragm.

1 I-valve yebhabhathane
I-valve ye-Butterfly iwumsebenzi wokuvula nokuvala wepuleti le-butterfly ongaqedwa ngokujikeleza ama-90° kuzungeze i-axis eqinile emzimbeni we-valve. I-valve ye-Butterfly incane ngobukhulu, isisindo sayo silula futhi isakhiwo sayo silula, futhi inezingxenye ezimbalwa kuphela. Futhi idinga ukujikeleza ama-90° kuphela; ingavulwa futhi ivalwe ngokushesha, futhi ukusebenza kulula. Uma i-valve ye-butterfly isesimweni esivulekile ngokuphelele, ubukhulu bepuleti le-butterfly yibo kuphela ukumelana lapho i-medium igeleza emzimbeni we-valve, ngakho-ke ukwehla kwengcindezi okukhiqizwa yi-valve kuncane kakhulu, ngakho-ke inezici zokulawula ukugeleza okungcono. I-valve ye-Butterfly ihlukaniswe ngokuthi uphawu oluthambile oluthambile kanye nophawu oluqinile lwensimbi. I-valve yokuvala enwebekayo, indandatho yokuvala ingafakwa emzimbeni we-valve noma inamathiselwe emngceleni wediski, ngokusebenza kahle kokuvala, okungasetshenziselwa ukugoqa, amapayipi e-vacuum aphakathi nendawo kanye nemidiya ebolile. Ama-valve anezimbobo zensimbi ngokuvamile aphila isikhathi eside kunalawo anezimbobo ezinwebekayo, kodwa kunzima ukufeza ukuvala okuphelele. Ngokuvamile asetshenziswa ngezikhathi lapho kunezinguquko ezinkulu ekugelezeni nasekuwehleni kwengcindezi futhi kudinga ukusebenza okuhle kokugoqa. Izivalo zensimbi zingazivumelanisa namazinga okushisa aphezulu okusebenza, kuyilapho izivalo ze-elastic zinesici sokulinganiselwa yizinga lokushisa.

2I-valve yesango
I-valve yesango ibhekisela ku-valve enomzimba wayo wokuvula nokuvala (ipuleti le-valve) eqhutshwa yisiqu se-valve futhi ihamba phezulu naphansi eduze kobuso bokuvala besihlalo se-valve, engaxhuma noma inqamule ukudlula koketshezi. Uma iqhathaniswa ne-valve ye-globe, i-valve yesango isebenza kangcono ekuvaleni, ukumelana noketshezi okuncane, umzamo omncane wokuvula nokuvala, futhi isebenza kahle ngokulungiswa okuthile. Ingenye yama-valve e-block asetshenziswa kakhulu. Ububi ukuthi usayizi wayo mkhulu, isakhiwo sayo siyinkimbinkimbi kakhulu kunese-globe valve, ubuso bokuvala kulula ukubugqoka, futhi akulula ukuyinakekela. Ngokuvamile, ayifaneleki ukugoqa. Ngokwesikhundla sentambo esiqwini se-valve yesango, ihlukaniswe ngezinhlobo ezimbili: uhlobo lwenduku evulekile kanye nohlobo lwenduku emnyama. Ngokwezici zesakhiwo sesango, ingahlukaniswa ngezinhlobo ezimbili: uhlobo lwe-wedge kanye nohlobo oluhambisanayo.

3 I-valve yokuhlola
Ivalvu yokuhlola iyivalvu engavimbela ngokuzenzakalelayo ukugeleza koketshezi emuva. I-valve yevalvu yokuhlola ivulwa ngaphansi kwesenzo sengcindezi yoketshezi, futhi uketshezi lugeleza lusuka ohlangothini lokungena luye ohlangothini lokukhipha. Uma ingcindezi ohlangothini lokungena iphansi kunaleyo ohlangothini lokukhipha, i-valve ye-valve izovala ngokuzenzakalelayo ngaphansi kwesenzo somehluko wengcindezi yoketshezi, amandla ayo adonsela phansi kanye nezinye izinto zokuvimbela uketshezi ukuthi lugeleze emuva. Ngokwesakhiwo, ingahlukaniswa ibe yivalvu yokuhlola yokuphakamisa kanye nevalvu yokuhlola yokushintsha. Uhlobo lokuphakamisa lusebenza kahle ekuvaleleni kanye nokumelana noketshezi okukhulu kunohlobo lokushintsha. Ukuze uthole imbobo yokumunca yepayipi yokumunca yephampu, kufanele kukhethwe ivalvu engezansi. Umsebenzi wayo ukugcwalisa ipayipi lokungenisa lephampu ngamanzi ngaphambi kokuqala iphampu; gcina ipayipi lokungenisa kanye nomzimba wephampu kugcwele amanzi ngemva kokuba iphampu imisiwe, ukuze kulungiselelwe ukuqala kabusha futhi. Ivalvu engezansi ngokuvamile ifakwa kuphela epayipini eliqondile lokungena kwephampu, kanti i-medium igeleza kusukela phansi kuya phezulu.

I-valve engu-4 ye-Globe
I-valve yomhlaba iyi-valve evaliwe phansi, futhi ilungu lokuvula nokuvala (i-valve) liqhutshwa yisiqu se-valve ukuze lihambe phezulu naphansi eduze kwe-axis yesihlalo se-valve (indawo yokuvala). Uma iqhathaniswa ne-valve yesango, inokusebenza okuhle kokulungisa, ukusebenza okungekuhle kokuvala, isakhiwo esilula, ukwenziwa nokugcinwa okulula, ukumelana okukhulu koketshezi kanye nentengo ephansi.

I-valve yebhola engu-5
Ingxenye yokuvula nokuvala yevalvu yebhola iyindilinga enembobo eyindilinga, futhi indilinga ijikeleza nesiqu sevalvu ukuze kutholakale ukuvulwa nokuvalwa kwevalvu. Ivalvu yebhola inesakhiwo esilula, ukushintsha okusheshayo, ukusebenza okulula, usayizi omncane, isisindo esincane, izingxenye ezimbalwa, ukumelana okuncane koketshezi, ukusebenza kahle kokuvala kanye nokugcinwa okulula.

I-valve ye-throttle engu-6
Isakhiwo se-throttle valve sifana kakhulu nese-globe valve ngaphandle kwe-valve disc. I-valve disc iyingxenye ye-throttling, futhi izimo ezahlukene zinezici ezahlukene. Ububanzi besihlalo se-valve akufanele bube bukhulu kakhulu, ngoba ukuphakama kokuvula kuncane. Izinga lokugeleza eliphakathi liyakhula, ngakho-ke kusheshisa ukuguguleka kwe-valve disc. I-throttle valve inobukhulu obuncane, isisindo esincane kanye nokusebenza okuhle kokulungisa, kodwa ukunemba kokulungisa akuphezulu.

I-valve yepulagi engu-7
I-valve yepulaki isebenzisa umzimba wepulaki onembobo edlulayo njengengxenye yokuvula nokuvala, futhi umzimba wepulaki ujikeleza ngesiqu se-valve ukuze kutholakale ukuvulwa nokuvalwa kwe-valve. I-valve yepulaki inezinzuzo zesakhiwo esilula, ukushintsha okusheshayo, ukusebenza okulula, ukumelana noketshezi okuncane, izingxenye ezimbalwa kanye nesisindo esincane. Kukhona ama-valve epulaki aqondile, aqondile kanye nanezindlela ezine. I-valve yepulaki eqondile isetshenziselwa ukusika i-medium, kanti ama-valve epulaki aqondile kanye nanezindlela ezine asetshenziselwa ukushintsha indlela ye-medium noma ukuhlukanisa i-medium.

I-valve ye-diaphragm engu-8
Ingxenye yokuvula nokuvala yevalvu ye-diaphragm iyi-diaphragm yerabha, ehlanganiswe phakathi komzimba wevalvu nesembozo sevalvu. Ingxenye ephakathi ephumayo ye-diaphragm inamathele esiqwini sevalvu, kanti umzimba wevalvu umbozwe ngerabha. Njengoba i-medium ingangeni emgodini wangaphakathi wesembozo sevalvu, isiqu sevalvu asidingi ibhokisi lokugcwala. Ivalvu ye-diaphragm inesakhiwo esilula, ukusebenza kahle kokuvala, ukulungiswa okulula kanye nokumelana okuncane koketshezi. Amavalvu e-diaphragm ahlukaniswe ngohlobo lwe-weir, uhlobo oluqondile, uhlobo lwe-angle yesokudla kanye nohlobo lokugeleza okuqondile.
