Ingaba ukhetho lwendlela yokudibanisa phakathi kwevalve yebhabhathane kunye nombhobho okanye izixhobo zichanekile okanye hayi ziyakuchaphazela ngokuthe ngqo amathuba okubaleka, ukuthontsiza, ukuvuza kunye nokuvuza kwevalve yombhobho. Iindlela zokudibanisa i-valve eziqhelekileyo ziquka: uxhulumaniso lwe-flange, uxhulumaniso lwe-wafer, uxhulumaniso lwe-welding ye-butt, uxhulumaniso lwe-threaded, uxhumano lwe-ferrule, uxhulumaniso lwe-clamp, uqhagamshelo lokuzitywina kunye nezinye iifom zokudibanisa.
A. Uqhagamshelwano lweFlange
Uqhagamshelwano lweFlange luivalve yebhabhathane eneflangedngeeflange kuzo zombini iziphelo zomzimba wevalvu, ezihambelana neeflange kumbhobho, kwaye zifakwe kumbhobho ngokubolisa iiflange. Uxhulumaniso lweFlange yeyona ndlela isetyenziswayo yokudibanisa kwiivalvu. Iiflange zihlulwe zibe yi-convex surface (RF), i-flat surface (FF), i-convex kunye ne-concave surface (MF), njl.
B. Uqhagamshelwano lweWafer
Ivalve ifakwe phakathi kwiiflange ezimbini, kunye nomzimba wevalve weivelufa yebhabhathanengokuqhelekileyo unomngxuma wokumisa ukuququzelela ukufakwa kunye nokubeka.
C. Uqhagamshelwano lweSolder
(1) Uqhagamshelo lwe-butt ye-welding: Zombini iziphelo zomzimba wevalvu zisetyenzwa zibe yimijelo yokuwelda ngeempundu ngokweemfuno ze-butt ze-welding, ezihambelana neendawo zokuwelda zombhobho, kwaye zimiliselwe kumbhobho ngokuwelda.
(2) Uqhagamshelo lwe-Socket welding: Zombini iziphelo zomzimba wevalve zicutshungulwa ngokweemfuno ze-socket welding, kwaye zidityaniswe nombhobho nge-socket welding.
D. Uqhagamshelwano ngemisonto
Udibaniso olunemisonto yindlela elula yokudibanisa kwaye isoloko isetyenziselwa iivalve ezincinci. Umzimba wevalvu ucutshungulwa ngokomgangatho ngamnye wentambo, kwaye kukho iindidi ezimbini zemisonto yangaphakathi kunye nentambo yangaphandle. Ihambelana nomsonto kumbhobho. Kukho iindidi ezimbini zoqhagamshelwano oluthungelweyo:
(1) Ukutywinwa ngokuthe ngqo: Imisonto yangaphakathi nangaphandle idlala indima yokutywina. Ukuze kuqinisekiswe ukuba uxhulumaniso aluvuzi, luhlala luzaliswe ngeoli ekhokelayo, i-thread hemp kunye ne-PTFE tape ye-raw material; phakathi kwazo PTFE tape impahla ekrwada isetyenziswa ngokubanzi; esi sixhobo sinokumelana ne-corrosion elungileyo kunye nesiphumo esihle sokutywinwa. Kulula ukuyisebenzisa kunye nokugcina. Xa uqhaqha, inokususwa ngokupheleleyo kuba ifilimu engagxiliyo, engcono kakhulu kuneoli ekhokelayo kunye ne-thread hemp.
(2) Ukutywinwa ngokungathanga ngqo: amandla okuqinisa intambo adluliselwa kwi-gasket phakathi kweendiza ezimbini, ukwenzela ukuba i-gasket idlale indima yokutywina.
E. uxhulumaniso lwe-ferrule
Umdibaniso we-ferrule uphuhliswe kuphela kwilizwe lam kwiminyaka yakutshanje. Ukudibanisa kwayo kunye nomgaqo wokutywinwa kukuba xa i-nut iqinisiwe, i-ferrule iphantsi koxinzelelo, ukwenzela ukuba umda we-ferrule ulume eludongeni olungaphandle lombhobho, kwaye i-cone yangaphandle ye-ferrule idibaniswe kwi-joint phantsi. uxinzelelo. Ingaphakathi lomzimba linxibelelene ngokusondeleyo nomgangatho wetapered, ngoko ke ukuvuza kunokuthintelwa ngokuthembekileyo. Njengeevalvu zesixhobo. Iinzuzo zolu hlobo loqhagamshelwano zezi:
(1) Ubungakanani obuncinci, ubunzima obulula, isakhiwo esilula, ukuchithwa okulula kunye nokuhlanganisa;
(2) Amandla okudibanisa okunamandla, uluhlu olubanzi lokusetyenziswa, ukuchasana noxinzelelo oluphezulu (1000 kg / cm 2), ukushisa okuphezulu (650 ° C) kunye nokutshitshiswa kunye nokungcangcazela;
(3) Iintlobo ezahlukeneyo zezinto eziphathekayo zinokukhethwa, ezifanelekileyo kwi-anti-corrosion;
(4) Iimfuno zokuchaneka komatshini aziphezulu;
(5) Ikulungele ukufakwa komgangatho ophezulu.
Okwangoku, ifom yoqhagamshelo lwe-ferrule yamkelwe kwezinye iimveliso zevalvu ezincinci kwilizwe lam.
F. Uxhulumaniso lweGrooved
Le yindlela yokudibanisa ngokukhawuleza, idinga kuphela iibholiti ezimbini, kwayeivalve yebhabhathane esekupheleniifanelekile kuxinzelelo oluphantsiiivalve butterflyezidla ngokuchithwa. ezifana neevalvu zococeko.
G. Uqhagamshelwano lwangaphakathi lokuziqinisa
Zonke ezi fom zoqhagamshelwano zingasentla zisebenzisa amandla angaphandle ukuphelisa uxinzelelo oluphakathi ukufezekisa ukutywinwa. Oku kulandelayo kuchaza ifom yokudibanisa yokuziqinisa usebenzisa uxinzelelo oluphakathi.
Umsesane wayo wokutywina ufakwe kwi-cone yangaphakathi kwaye wenze i-angle ethile kunye necala elijongene ne-medium. Uxinzelelo lwe-medium ludluliselwa kwi-cone yangaphakathi kwaye emva koko kwindandatho yokutywina. Kwi-cone surface ye-angle ethile, amandla amacandelo amabini ayenziwa, enye kunye Umgca ophakathi womzimba we-valve uhambelana nangaphandle, kwaye enye icinezelwe kudonga lwangaphakathi lomzimba wevalve. Amandla okugqibela ngawona aziqinisayo. Uxinzelelo olukhulu oluphakathi, kokukhona amandla aziqinisayo. Ngoko ke, le fomu yokudibanisa ifanelekile kwiivalve eziphezulu zoxinzelelo.
Xa kuthelekiswa noqhagamshelo lwe-flange, igcina izinto ezininzi kunye nabasebenzi, kodwa ifuna ukulayishwa kwangaphambili, ukwenzela ukuba isetyenziswe ngokuthembekileyo xa uxinzelelo kwi-valve lungekho phezulu. Iivalvu ezenziwe kusetyenziswa umgaqo wokuziqinisa ngokwawo zizivalo zoxinzelelo oluphezulu.
Kukho iindlela ezininzi zokudibanisa i-valve, umzekelo, ezinye iivalve ezincinci ezingafuneki ukuba zisuswe zifakwe kwimibhobho; ezinye iivalvu ezingezizo ezentsimbi ziqhagamshelwe ngeesokethi njalo njalo. Abasebenzisi bevalvu kufuneka baphathwe ngokwemeko ethile.
Phawula:
(1) Zonke iindlela zokudibanisa kufuneka zibhekiselele kwimigangatho ehambelanayo kwaye icacise imigangatho yokukhusela i-valve ekhethiweyo ukuba ifakwe.
(2) Ngokuqhelekileyo, umbhobho wedayamitha enkulu kunye nevalve zidityaniswe ngeflange, kwaye umbhobho wobubanzi obuncinci kunye nevalve ziqhagamshelwe ngomsonto.
