1. Umgaqo wokuSebenza we-DBB Plve
I-valve ye-plug plug yibhloko ephindwe kabini kunye nevalve ephumayo: I-valve ye-valve enye enendawo yokutywina, xa isendawo evaliweyo, inokubhloksa i-valve ephezulu, kwaye ikhutshiwe phakathi kwendawo yokutywina kwendawo yokutywina i-valve ye-valve iphumelele itshaneli.
Ubume be-DBB yePlag yePlick yahlulahlulwe yangamacandelo amahlanu: i-bonnet ephezulu, iplagi, itywina i-ring, i-valve kunye ne-bonnet esezantsi.
Iplagi yomzimba we-DBB ye-DBB ye-DBB iqumba iplagi ye-vall ye-valve kunye neediski ezimbini zeVolve zenza iplagi ye-cylindrical plug. I-valves disves kumacala omabini zincitshiswa ngemigangatho yokutywina yerabha, kwaye embindini yiplagi ye-Wedge. Xa iveni ivuliwe, indlela yodluliselwa i-valve inyuka, kwaye iqhube i-valve kumacala omabini anokuvalwa, kwaye emva koko iqhube iplagi yomzimba ukujikeleza i-90 ° Kwindawo evulekileyo yevali. Xa ivalve ivaliwe, indlela yodluliselo ijikeleza i-Palve Plug i-90 ° ukuya kwindawo evaliweyo, kwaye ityhila iplagi ye-valve ihla ngezantsi kwe-valve kwaye ingasahambi ezantsi, embindini I-valg iplagi iqhubeka ihla, kwaye amacala omabini evali atyhilwe yinqwelomoya. I-disc isuka kumphezulu wokutywina komzimba wevali, ukuze umhlaba othambileyo wokutywina kwe-disc kunye nomphezulu wokutywina kwe-valve inyanzelekile ukutywinwa. Intshukumo yengxabano inokuqinisekisa ukuba inkonzo yenkonzo yetywina le-valve.
I-2. Izibonelelo ze-DBB Palve
I-valve ye-dbb i-valve ineempawu eziphakamileyo zokutywina. Ngendlela eyahlukileyo ye-Wedge-ye-W-Deped kunye noyilo lwe-Operatoratoratricatoratorator kunye ne-valve disw kunye ne-valve disver kunye ne-valve itywina lokutywina, ngenxa yoko ukuphepha isizukulwana sobumbano, ukuphelisa itywina kwaye ubuyele ubomi bovelisi. Ubomi benkonzo buphucula ukuthembeka kwevalve. Kwangelo xesha, ukuqwalaselwa komgangatho wenkqubo yoncedo ye-thermal kuqinisekisa ukusebenza kwevali evalelweyo, kwaye kwangaxeshanye kubonelela ngokuqinisekiswa komgca wokuvalwa kwevali.
Iimpawu ezintandathu ze-DBB Plve

4) Inkqubo yenkqubo yoncedo ye-therb ye-DBB ye-DBB ikhuphe ngokuzenzekelayo i-vality castration xa inokwenzeka, ukuvumela ukuhlolwa kwe-intanethi okwethutyana kunye nokuqinisekiswa kwepalve yokutywina.
I-5) Isalathiso sexesha lokwenyani se-Valve, kwaye i-Assuremer Iname kwi-valve stem inokuphendula imeko yexesha lokwenyani.
I-6) Indawo yokuphuma kwe-loger ephantsi inokukhupha ukungcola, kwaye inokukhupha amanzi kwindawo ye-valve ebusika ukunqanda umzimba wevali ukuba wonakaliswe ngenxa yokwandiswa kwequlus.
3. Uhlalutyo lokungaphumeleli kwe-veli ye-dbb plug
I-1) I-PIN yesikhokelo yaphukile. IPIN yesikhokelo icwangcisiwe kwi-valve ye-valve ithwele i-bracket, kwaye esinye isiphelo sinemikhono kwi-L-Fed kwisikhokelo se-L-Groove kwi-valve steve. Xa i-valve stem iguqula kwaye icinyiwe phantsi kwesenzo sesenzo, iPIN yesikhokelo ithintelwe sisikhokelo i-Groove, iverove yenziwe. Xa ivalve ivuliwe, iplagi iphakanyisiwe kwaye ijikelezwe ngama-90 °, kwaye xa ivalve ivaliwe, ijikelezwe nge-90 ° kwaye icinezelwe phantsi.
Inyathelo lesiqu se-valve phantsi kwesenzo se-PIN isikhokelo sinokubekwa kwintshukumo ethe tye kwaye ngokuthe nkqo kunye nesenzo sesenzo. Xa ivalve ivuliwe, i-valve iqhuba i-groove ye-L-Groove ukuba iphakame ngokuthe nkqo de iPIN yeSikhokelo ifikelela kwi-Groove yesikhokelo, isantya esithe nkqo sikhawulezisa ukujikeleza; Xa ivalve ivaliwe, i-valve stemp iqhuba i-groove ye-L-Groove yokujikeleza kwicala elithe tyaba xa isikhokelo se-Groove sifikelela kwi-Groove ye-Groove ye-L-Groove, inkohliso ethe nkqo iyakhawuleza kwaye icinezelwe phantsi. Ke ngoko, iPIN yesikhokelo iphantsi kweyona nto iphambili xa i-Groove ijika i-groove ijika, kwaye yeyona ilula ukufumana amandla empembelelo kwindawo ethe nkqo kwaye ethe nkqo ngaxeshanye. Izikhonkwane ezaphukileyo.
Emva kokuba iPIN yesikhokelo yaphukile, ivalve ikwimo apho iplagi isuswe khona kodwa iplagi ye valve ayikhange ijikelezwe, kwaye ububanzi beplangi ye-valve bungaphezulu kobubanzi bomzimba wevali. I-gap idlula kodwa isilele ukufikelela kwindawo evulekileyo ngokupheleleyo. Ukusasazeka kwendawo edlulayo, inokugwetywa ukuba iphi iphi ivali yeValve. Enye indlela yokugweba ukwahlukana kwePIN yesikhokelo kukujonga ukuba iphi iPIN yesalathiso esilungiselelwe ukuphela kwe-valve ivuliwe xa ivaliwe. Isenzo sokujikeleza.
2) I-Abection yokungena. Kuba kukho umsantsa omkhulu phakathi kweplagi ye-vag kunye ne-vality kunye nobunzulu be-valve kwindawo ethe nkqo iphantsi kunelo yombhobho, ukungcola kufakwe ezantsi kwe-valve xa udlula. Xa ivalve ivaliwe, iplagi ye-vag icinezelwe phantsi, kwaye ukungaziphathi kakuhle kuyasuswa yiplagi ye valve. Ithatyathwe emazantsi e-valve, kwaye emva koko, emva koko ifihlwe, ungqimba "lwe-sedimentary Rock lusekwa. Xa ubukhulu becala lokungcola lingaphezulu komda phakathi kweplagi yeValve kunye nesitulo sevali kwaye asisakwazi ukucinezelwa, siyakuthintela ukubetha kweplagi ye-vall. Intshukumo ibangela i-valve ukuze ingavali kakuhle okanye i-overtorque.
(3) ukuvuza kwangaphakathi kwevalve. Umzobo wangaphakathi wevalve kukwenzakala okubulalayo kwivalve evaliweyo. Ukuvuza okungaphakathi kwangaphakathi, ukuthoba ukuthembeka kwevalve. Ukuvuza ngaphakathi kweValve yokutshintshela kweoyile kunokubangela iingozi ze-oyile ezinzulu, ke ukukhetha ivalve yokutshintshela kweoyile kufuneka ithathelwe ingqalelo. Umsebenzi wokuvuza umvuni wangaphakathi wevali kunye nobunzima bokunyanga ngaphakathi kwi-leaki. I-valve ye-dbb plug inomsebenzi olula wokuvumisa kunye nokusebenzisa i-leakued kunye nendlela yangaphakathi yonyango, kunye nendawo yokutywina ephindiweyo ye-DBB ye-DBB ye-DBB ye-DBB iyenza ukuba ifumane umsebenzi osikiweyo, ke ioyile Imveliso yemveliso yokutshintsha kwe-oyile yeoyile ehlaziyiweyo isebenzisa iplagi ye-dbb.
Indlela yokufunyanwa kwe-DBB ye-Dobb ye-Vigi ye-Vigi ye-Leakuaken Leasege: Vula iPlastali yoNcedo lweValve, ukuba i-Piedle iphume iphuma, kwaye igqiba ivalve ingenamsebenzi wangaphakathi we-valve ; Ukuba kukho ukuphuma kwe-upowflow ephakathi, kuyangqineka ukuba ivalve inomzobo wangaphakathi, kodwa akunakwenzeka ukuba ifumane ukuba leliphi icala levalve ivuza ngaphakathi. Kuphela kukucutha ivali esinokuyazi imeko ethile yokuvuza kwangaphakathi. Indlela yokuchonga yangaphakathi yokufunyanwa kwe-DBB ye-DBB inokuthi ifumanise ukufunyanwa ngokukhawuleza kwendawo, kwaye ikwazi ukubona umzobo wangaphakathi wevalini xa utshintshile iingozi ze-oyile ezahlukeneyo.
I-4. Ukuchitha kunye nokuhlolwa kwe-vag ye-dbb plug
Ukuhlolwa kunye nokugcinwa kubandakanya uvavanyo lwe-Intanethi kunye novavanyo olungachanekanga. Ngexesha lolondolozo lwe-Intanethi, i-valve ibhulukhwe kunye ne-flange igcinwe kumbhobho, kwaye injongo yesondlo ifezekiswa ngokuseka izinto ze-valve.
Ukuxakeka kunye nokuhlolwa kwe-valb ye-DBB ye-DBB yahlulwe yaba yindlela ephezulu yengozi kunye nendlela ephantsi. Indlela ephezulu yengozi ikakhulu ijolise ikakhulu kwiingxaki ezikhoyo kwinxalenye ye-valve efana ne-valve stem, iplate yesiqhelo, kunye neplagi. Eyona ndlela iphazamisayo ijolise ikakhulu kwiingxaki ezikhoyo kwisiphelo esisezantsi samatywina, i-valves, iipleyiti eziphantsi, kunye neevali ze-village.
Indlela ephezulu kakhulu isusa i-actuator, i-valve stem, i-geland, kunye nekhava ephezulu ye-vali, emva koko iphakamise i-valve stem kunye neplagi ye-valve. Xa usebenzisa indlela ephezulu, ngenxa yokusika nokucinezelwa kwetywina lokupakisha ngexesha lokufakelwa kunye nokunxiba kunye nokukrazula i-valve ngexesha lokuvula i-valve kunye nenkqubo yokuvala, ayinakusetyenziswa. Vula i-valve kwisikhundla esivulekileyo kwangaphambili ukuthintela iplagi ye-valve isuswe ngokulula xa i-valve icinezelwe.
Indlela egqwethekileyo ifuna kuphela ukususa ikhava esezantsi yesezantsi ukuze igqwethe iinxalenye ezihambelanayo. Xa usebenzisa indlela egqwethekileyo ukukhangela i-Palve Dis, ivalve ayinakubekwa kwindawo evalekileyo epheleleyo, ukwenzela ukuthintela i-Palve Disne ayinakukhutshwa xa ivalve icinezelwe xa ivalve icinezelwe xa ivalve icinezelwe xa ivalve icinezelwe xa ivalve icinezelwe nini. Ngenxa yoqhagamshelo olunokususwa phakathi kwe-Palve disve kunye ne-vag ye-Dovetail Groove, isigqubuthelo esingaphantsi sisuswe ngaxeshanye xa isigqubuthelo esisezantsi sisusiwe ngenxa yokonakala kwe-valve idiski.
Indlela ephezulu kakhulu kunye nendlela ephantsi ye-DBB yevali ye-DBB ayifuni ukuhambisa umzimba wevalve, ukuze ilungiswe kwi-Intanethi. Inkqubo yoNcedo lweValve isetiwe kwi-Valveli Mzimba, ke indlela ephezulu yendlela ephezulu kunye nendlela esezantsi ayidingi ukuba inkqubo yoncedo lobushushu, eyenza lula inkqubo yolondolozo kwaye iphucule ukusebenza kwenkqubo yolondolozo. Ukuchitha kunye nokuhlolwa akubandakanyi umzimba ophambili webhulukuthelo, kodwa ivalve kufuneka ivalwe ngokupheleleyo ukuthintela iphakathi ukusuka kwi-Peewlity ehambayo.
