Iifom eziphambili zevalvu ziiflange, imisonto, imikhono yekhadi, iiclamps, i-intemal self tightening, i-welding, iikliphu njalo njalo. Zifanelekele ezahlukeneyo
Izihlandlo, kwaye ezilandelayo zichazwe ngokweenkcukacha.
I-1, uxhulumaniso lwe-flange yeyona fomu yokudibanisa esetyenziswa rhoqo kwiivalvu. Ngokwemilo yendawo edibeneyo, inokwahlulwa ibe yi
iintlobo ezilandelayo. 1) uhlobo olugudileyo: lusetyenziselwa iivalvu ezinoxinzelelo oluphantsi. Ukucutshungulwa kukulungele ngakumbi 2) uhlobo lwe-concave kunye ne-convex. ukusebenza okuphezulu
uxinzelelo, unokusebenzisa i-washer enzima 3) i-tenon kunye ne-grooves. kunye newasha enkulu yokuguqula iplastiki, kwindawo enomhlwa isetyenziswa kakhulu, ukutywinwa okungcono
isiphumo.
4) i-trapezoidal groove: sebenzisa intsimbi yentsimbi e-oval njengewasha, esetyenziselwa uxinzelelo olungaphezulu kwe-64 kg 1 square centimeter, okanye phezulu.
ivelufa yobushushu.
5) uhlobo lwe-lens: i-gasket i-lens shape, eyenziwe ngetsimbi. Ivalve yoxinzelelo oluphezulu okanye ivalve yobushushu obuphezulu yoxinzelelo lokusebenza olukhulu kune-100 kg 1 isikwere
isentimitha. 6) 0 uhlobo lweringi: Olu luhlobo olutsha loqhagamshelo lweflange, luphuhliswa ngokubonakala kwamakhonkco erabha ayi-0, kwaye ingaphezulu.
ethembekileyo kwisiphumo sokutywina kunewasha eqhelekileyo eflethi. I-2, uxhulumaniso lwentambo yindlela elula yokudibanisa, esetyenziswa ngokuqhelekileyo kwiivalve ezincinci. Yahlulwe
kwiimeko ezimbini: 1) ukutywinwa ngokuthe ngqo: imicu ephakathi kunye neyangaphandle idlala indima ngokuthe ngqo ekutywinweni. Ukuqinisekisa ukuba akukho kuvuza, ihlala igcwala ioyile yelothe,
hemp, kunye nepoltetrafluoroethylene. I-polytetrafluoroethylene ekrwada isetyenziswa ngokubanzi kusetyenziso lwemihla ngemihla. Izinto eziphathekayo zinokuxhathisa okulungileyo kokubola,
isiphumo esihle sokutywina, ukusetyenziswa ngokufanelekileyo kunye nokugcinwa. Inokususwa ngokupheleleyo xa kuqhawulwa, kuba ngumaleko ongancangathi obhityileyo.
I-Membrane iphezulu kakhulu kuneoli yelothe kunye ne-hemp.
2) isitywina esingathanga ngqo: amandla okuqinisa intambo adluliselwa kwi-gasket phakathi kweendiza ezimbini, ukwenzela ukuba i-washers ivalwe.
I-3, uqhagamshelo lonxibelelwano lomkhono wekhadi luphuhliswa kuphela kwiminyaka yakutshanje eTshayina. Ukudibanisa kwayo kunye nomgaqo wokutywinwa kukuba xa i-nut
iqinisiwe, ibhatyi iphantsi koxinzelelo, okwenza ukuba i-blade ilume eludongeni lwangaphandle lombhobho, kwaye i-cone yangaphandle yejacket isondele.
kufuphi ne-conical surface ye-joint phantsi koxinzelelo, ngoko inokuthintela ngokuthembekileyo ukuvuza. Iinzuzo zolu hlobo loqhagamshelwano zi. 1) ubungakanani obuncinci,
ubunzima obulula, isakhiwo esilula, ukuchithwa okulula kunye nokuqhaqha; 2) amandla oqhagamshelwano oluqinileyo, uluhlu olubanzi lokusetyenziswa, uxinzelelo oluphezulu (1000 kg 1 sq cm), phezulu
iqondo lobushushu (650 degrees C) kunye shock vibratin; 3) unokukhetha izinto ezahlukeneyo, i-anticorrosion corrosion; 4) ukuchaneka kokucubungula akukho phezulu; 5)
istallaion elula kwindawo ephakamileyo. Okwangoku, uhlobo loqhagamshelo lomkhono wekhadi lwamkelwe kwiimveliso ezincinci zevalvu eTshayina.
I-4, uxhulumaniso lwehupu yindlela yokudibanisa ngokukhawuleza. Ifuna kuphela iibholiti ezimbini, kwaye ifanelekile kwiivalvu zoxinzelelo oluphantsi ezihlala ziqhaqhwa.
I-5, uqhagamshelo lwe-intemal self tight ngaphezu kwazo zonke iintlobo zoqhagamshelo, zisebenzisa amandla agqithisileyo ukuchasana noxinzelelo oluphakathi, kunye nokuqonda ukutywinwa.
Ukulandelana kukwazisa ifom yodibaniso oluziqinisayo usebenzisa uxinzelelo oluphakathi. Umsesane wayo wokutywina ufakwe kwi-cone yangaphakathi, kunye nokuchasene
kwicala eliphakathi ukuya kwi-angle ethile, uxinzelelo oluphakathi ludlula kwi-cone yangaphakathi kwaye ludlulele kwindandatho yokutywina. Kwikhowuni ye-engile ethile,
amasebe amabini aveliswa, elinye linxusene nomgca osembindini womzimba wevalvu, kwaye elinye licinezelwe ukuya kudonga lwangaphakathi lomzimba wevalvu. I
amandla emva kwala mandla kukuziqinisa. Okukhona uxinzelelo oluphakathi, kokukhona uziqinisa ngamandla. Ngoko olu xhulumaniso lufanelekile
iivalve zoxinzelelo oluphezulu. Yeyona nto ibonakalayo kwaye inamandla ngaphezu koqhagamshelo lweflange, kodwa ikwafuna amandla athile okuqinisa kwangaphambili, ukuze ikwazi
isetyenziswe ngokuthembekileyo xa uxinzelelo ngaphakathi kwevalve lungekho phezulu. Ivalve eyenziwe ngomgaqo oziqinisayo wokuzitywina idla ngokuba yivalve yoxinzelelo oluphezulu.
6, i-welding 1) i-butt welding: ifanelekile kwizihlandlo ezinoxinzelelo oluphezulu. 2) i-socket welding: kwiimeko zoxinzelelo oluphantsi.
7. I-clamp idla ngokusetyenziselwa ukusebenza kwamandla ombane aphantsi, okufana noqhagamshelo lwevalve yebhabhathane.
8, uqhagamshelo lwevalve luninzi lwefomu, umzekelo, ezinye iivalve ezingezizo ezentsimbi, zisebenzisa uqhagamshelo lwesokhethi, ukuwelda njalo njalo, umsebenzisi wevalve kufuneka
baphathwe ngokwetyala.
