Umahluko ophambili phakathi kwe-valve esuka ehlobeni, uhlalutyo lweempawu zoyilo lweloyilo likuvumela ukuba wenze ukhetho olufanelekileyo lwesixhobo sokuqiniswa xa kufakwa umbhobho.
Iskimu se-valve yomtshato.
I-valves yesixhobo
Ivalve sisixhobo sokuqiniswa esinendawo yokuvalwa kwi-disc, iphepha okanye i-Wedge ihamba ecaleni kwe-shows etyhidiweyo kwi-Axis ye-Axis ephakathi.Kuxhomekeka kuyilo lwevalve, kunokubakho isicatshulwa kwaye kuncitshiswe ukuba nemingxunya ye-riding ngaphantsi kobubanzi bombhobho.
Kuxhomekeka kwi-jometri yejometri, iivalvuzwa zahlulwe kwi-parallel kunye ne-Wedge. Ii-valve ze-Wedge zixhotywe nge-Wedge shutter enemigangatho yokutywina ekhoyo kwi-engile kwelinye. I-Shutter Wedge inokuba yi-elastic eqinileyo, i-rigid eqinileyo okanye i-disc.
I-valves valves zixhotyiswe ngezitshisi zomphezulu weTywina Olu luyilo lunokuba sisiqwengana esinye (intombi) okanye ezimbini-disc.
Iivalves zinokuxhotyiswa nge-spindle ezifudukayo (isitokhwe) kunye nokungabuyisi (isiphatho esijikelezayo). Bahluke ngoyilo lwe-screw isibini, esishukumisa i-shutter. I-valves ene-spindle ejikelezayo inobukhulu obuncinci bokwakha.
Izibonelelo kunye nokungalungisi kweeValves
Umzobo wesixhobo seValve: Umzimba wevalve, 2 - i-Nut, i-Warher, i-4-Gall, i-7-Gatch, i-10 - i-valt, i-wilnik bush, 11 Iflewhesel, 12 - I-Honer, 13 - isikere, 14 - I-Warsher.
Eyona nto iphambili yeevalves kukuba akukho nto iphambili koxinzelelo lwendlela ephakathi ngexesha lenkqubo yokuhambisa umzimba, nto leyo ngoko, kuyo ingumzamo ofunekayo wokuhambisa i-shutter. Ukungqinelana kokuhamba kwendawo ephakathi kunye nokuchasana okuncinci kurhulumente ovulekileyo kuya kubaluleka.
Ngenxa yoyilo lwe-Symetrical, ukusetyenziswa kweevalves kunokusetyenziswa kwiindlela ezahlukeneyo zokuhamba kweyona ndawo iphakathi, ngelixa ingeyiyo indibano engaphezulu kakhulu, ngelixa i-changes chapveys kwaye inyanzelekile ukuba itshintshe indlela yokuhamba kwendawo yangaphakathi.
Eyona nto iphosakeleyo yesakhiwo kukuba kwinkqubo yokuhambisa umzimba wokusebenza kweevalves, imbambano eyomeleleyo yenzeka. Iivalvers zinomhlaba omkhulu wokwakha ngenxa yesidingo sokwandisa intonga.
Inqaku lesihloko: Igumbi lokuhlala 9 sq m: indlela yokwenza uyilo lwangaphakathi?
Xa i-shutter ikwindawo ephakathi, icandelo le-soaside ligquma ngokuyinxenye, ukuhamba okuqhubayo ukuya kwiindawo eziphantsi zokukhawula umphezulu we-ring, ukuveza ukunxiba okunendawo ephakathi. Ke ngoko, emva kokusebenza kwimodi yokuvala inxenye, ivalve ayibonelelwanga ngokuqina ngokwaneleyo xa zivaliwe. Oku kungasebenzi kakuhle kuyinto yendalo kwiindidi ezahlukeneyo zokuqiniswa kunye nokunciphisa ukusetyenziswa kwevali njengento ehlengahlengiswayo. Ukongeza, iimpawu ezilawulayo zeevalveve zingonelisekanga.
Isicelo kunye nokusebenza kweevalves
Iivalves zisetyenziswa kwimibhobho enobubanzi obungaphezulu kwe-50 mm ngaphezulu kwe-50 mm, apho i-ofisi egudileyo yecandelo lomnqamlezo iyimfuneko ukuthintela impembelelo ye-hydraulic.Zisetyenziswa kwimo yomoya kunye neenkqubo zomoya zokuhlaselwa komoya (kunye nakwindawo yokufudumeza), i-analogue yoyilo lwevalve yi-venthel yokutshinga, eyiphepha lesinyithi, elihamba kwi-axis ye-suct yomoya.
Sukwenza ngaphandle kweevalvu nakwisixhobo senkqubo yokufaka imibhobho kunye neenkqubo zokuhambisa iimpahla, umbhobho wegesi, kunye nezinye iinkqubo zobunjineli zezobunjineli. Uninzi ngempazamo lukholelwa ukuba iiValves ziintlobo ezahlukeneyo zevumba, kodwa ezi zizixhobo zahlukileyo ezineempawu ezahlukeneyo zokubonisa iimpawu zomsebenzi.
Isixhobo kunye neevalves
Isikimu seSango le-Sewerry: I-1-Sewber, isikhokelo se-2-3, isihlalo esi-3, isithuba se-4, esi-8, i-8-hainter, i-10-painter, i-10-hainter, i-10-hainter, i-10-paran, 11- I-12-ioyile, i-13 ring.
Ivali yivali, i-shutter yendlela ehamba nesibini esinentambo. Uyilo lwenziwe kwiNguqulo yeTrintity (Coupling) kunye nokuqhagamshela kwiflethi yemibhobho.
Kuxhomekeka ekubeni ilungiselelo lemveliso kunye nonxibelelwano lwegalelo, i-valves edlulayo eyahlulwe. Iindidi zeendinyana zibandakanya ukwakhangoko ukuba i-axes yemveliso kunye nemibhobho yokudibanisa ihambelana okanye ikhutshelwe ngaphandle. I-valve ye-angular, ixhotyiswe nge-axes ye-perpendicrocular.
Kuxhomekeka kwinjongo, bahlulwe ukuba bavaliwe, ukhuseleko, ukulawula, ukunqunyulwa, ukudlula, ukubuyela umva.
Ivali inokuba neeveki ezilungileyo kwaye iiveki ezimbini. Iveki yeveki, ngohlobo lwe-shutter yahlulahlulwe yaba yinaliti nesitya. Ivali enolawulo lwezandla apho i-shutter ihamba khona ngesibini esinentambo, ihlala ibizwa yivalve. Ukwahlula-hlula nokumisa i-valves. Injongo ye-valves evaliweyo yindawo epheleleyo yokuhamba okuphakathi, kuba oku baxhotyiswe ngomzimba opholileyo.

Imizobo ye-membrane - uyilo lwe-rublap ekusetyenzwa kuyo ekuhlangene kwendawo yenziwa usebenzisa i-membrane ye-elastic of debrane (iplastiki, irabha). Ezi nkqubo zenziwe nge-iron ye-iron yokuthoba i-Porrosion Izixhobo ezingavisiyoliyo (irabha, iplasitiki, i-enamel).
I-Hose Valve yiyilo yokuqiniswa, apho i-overlap yokuhamba okuphakathi iphunyezwa ngenxa yokuqinisa i-hose yerabha ngaphakathi kwevali. I-valves zisetyenziswa zombini kunye ne-head kunye ne-raticral hose.
I-Scheme ye-skiels i-valves ezinesibindi sokubuyisa.
I-valve yokuphefumla yenzelwe ukukhululwa komoya oqokelelweyo okanye umphunga kunye nokuthintela ukwenziwa kweetanki kwiitanki kwinkqubo yokuphefumla "enkulu" kunye "encinci". Umxholo "wokuphefumla okukhulu" okukhulu "kwiindleko kunye nokuhamba kwe-fluid," encinci "ibangelwa kukuguquguquka kobushushu.
Ngenxa yeevalva zokujonga, kunokwenzeka ukuthintela ukwenziwa komda we-Preser ophakathi. Kwiivali zokujonga, umbutho okutshintshileyo uvula ngomso ngqo wephakathi kwaye uvaliwe ngokutshintsha kwakhona. Uyilo oluphakamileyo lwevalve lunendawo evaliweyo eyenza intshukumo ephindayo. Ukwakhiwa, kuxhotywe nge-mesh, ifakwe ekuqaleni kombhobho we-puipe. I-valve yokujonga ireyitha ixhotywe nge-shutter ijikeleze i-axis ethe tyaba, efumaneka ngaphezulu kwendawo yesitulo sevali.
Izibonelelo kunye neempazamo zevali
Eyona nto iphambili yevali kukungabikho koxinzelelo lwendawo yokutywina, xa ivaliwe, kuba i-shutter ihamba ngendlela efanelekileyo, ethi inciphise umngcipheko womonakalo. Ivalve inomphakamo omncinci xa kuthelekiswa ne-valve ngenxa yokuba i-stindle yesichethi incinci kwaye ayikho ngaphezulu ¼ ububanzi bombhobho. Nangona kunjalo, banobude obukhulu bokwakha, njengoko kufuneka bahambisane nokuhamba ngaphakathi kwetyala.
E-Valve, i-shutter ihamba ngokulinganayo, ngexesha lokuvala inkqubo, iindawo zokutywina kwengxabano azivavanywanga, kwaye oku kuthintela ukwenzeka kokuphikisa.
Ukunqongophala kweevalves kukuphikisana okukhulu kwe-hydraulic. Yenzeka ngenxa yotshintsho kwicala lokuhamba kwephakathi. Utshintsho olunjalo luphezulu kabini ngaphakathi kwesixhobo sezindlu.
Ivalve iphawuleka ukuba inemida ngexesha lokusebenza kwaye inokusetyenziswa kuphela kwicandelo elithile lokuhamba kwendawo esebenzayo. Uyilo lumiselwe kwangaphambili ukuba ukuhamba kufuneka kuvuza phantsi kweplate kwaye kubeke uxinzelelo kuyo ukusuka kwi-sardle kwindawo evaliweyo. Ukuvula i-valve kuyacaphukisa imboji yeplate kwi-saddle. Ukuba ivalve igxile kwelinye icala, emva koko kwindawo evaliweyo, ipleyiti iya kuqhotyoshelwa kwi-sardle, eya kuthi ibonakale kubunzima xa kuvulwa. Ngenxa yoko, ukwaphuka kweplate kwintonga kunye nemveliso yevali iphume.

I-valve yomahluko kunye ne-valve
Nguwuphi umahluko phakathi kwevalve evenkileni? Umahluko kungenxa yoyilo lwamalungu awo okuvala. Kwintshontsho, ukuhamba kwegesi okanye ukugqobhoza kwegesi kunye nevalve, ecinezelwe kwi-sardle kwiinqwelomoya ezithe tyaba, koku, ukugoba kabini kwegesi, kodwa Ukuxhathisa ukunyuka.
Ngokungafaniyo nevalve ye-valve, ivalve ixhotywe ngeflethi yeflethi okanye i-coneoid shutter, ishukumisa ihambo ephindaphindiweyo ecaleni kwe-boddle.
E-valves, ukugeleza kuyaphambana ngenxa ye-uperper okanye i-cone, iwehhwit petpendicular kwicala lokuhamba.
Ngoyilo olufanelekileyo lwe-valve, akukho mqobo mingxunya wemingxunya esebenzayo, xa kuthelekiswa negalelo kunye nemveliso. Kwimeko yokusebenzisa i-valve, inani leendlela zokhetho zinokwenzeka. Kwimibhobho emininzi, zonke iivali ezinamavili ezinamavili zifakiwe, apho ububanzi bendawo yokusebenza ihambelana nobubanzi bombhobho, kunjalo, kuhlala kunciphisa i-torve ye-torque kwaye isetyenzisiwe yenza ukuba ikwazi ukunciphisa umphezulu wophawu.
Ngoxinzelelo oluphezulu okanye ububanzi bemibhobho, ngaphezulu kwe-300 mm ngamava asebenza kakuhle. Ivalve ikwayilo olulalileyo, isiphumo sexabiso eliphantsi. Ukongeza, kulula ukujikeleza ngoxinzelelo olukhulu, kodwa kwingcinezelo ephezulu njengomnqweno wokucinezela ivalda evela kwi-sardle, umthwalo owongezelelweyo owenziwe. Kwi-valves ukuba ingekho ngokupheleleyo, njengoko ingenazigoda.
Ngenxa yengcinezelo yendlela enye, i-funse engaphezulu kweflethi ukuya kwi-SADDLE iqinisekisiwe, yenza iivasta zinesixhobo esitshixwayo.
Inqaku lokubhloka le-valves linokuphelisa ngokupheleleyo ukuntywila kwegesi okanye ulwelo, okanye ukuvulwa ngokupheleleyo, iivalves zinokwenza umsebenzi wokulawula izinto.
