Ukufakwa kweevalve zebhola ezidityanisiweyo ngokupheleleyo

(1) Ukuphakamisa.Ivalve kufuneka iphakanyiswe ngendlela echanekileyo.Ukukhusela isiqu sevalve, musa ukubophelela ikhonkco lokunyusa kwivili lesandla, kwibhokisi yegiya okanye kwi-actuator.Musa ukususa iminqwazi yokukhusela kuzo zozibini iziphelo zomkhono wevalvu phambi kokuba welding.

(2) Ukuwelda.Udibaniso kunye nombhobho oyintloko ludityanisiwe.Umgangatho we-welding seam kufuneka uhlangabezane nomgangatho othi "Radiography of Welded Joints of Disk Flexion Fusion Welding" (GB3323-2005) iBakala II.Ngokuqhelekileyo, i-welding enye ayinakuqinisekisa ngokupheleleyo zonke iziqinisekiso.Ngoko ke, xa uyala ivalve, umenzi kufuneka acele umenzi ukuba afake i-1.0m kuzo zombini iziphelo zevalve.I-tube ye-sleeve, xa i-welding seam ingafanelekanga, kukho ubude obaneleyo bokunqumla i-welding seam engafanelekanga kunye ne-weld kwakhona.Xa ivalve yebhola kunye nombhobho zidityanisiwe, ivalve kufuneka ibekwi-100% kwindawo evuleke ngokupheleleyo ukukhusela ivalve yebhola ukuba yonakaliswe kukutshiza i-welding slag, kwaye kwangaxeshanye uqinisekise ivalve. idlula i-140 degrees celsius, kwaye amanyathelo okupholisa afanelekileyo anokuthathwa ukuba kuyimfuneko.

(3) Ukwakhiwa kwevalufa kakuhle.Yamkela uyilo olukhethekileyo lolwakhiwo kwaye ineempawu zokungagcini.Ngaphambi kokuba ungcwatywe, sebenzisa i-Pu ekhethekileyo yokukhusela i-corrosion ngaphandle kwevalve.Isiqu sevalve sandiswe ngokufanelekileyo ngokobunzulu bomhlaba, ukuze abasebenzi bagqibezele imisebenzi eyahlukeneyo emhlabeni.Emva kokuba kungcwatywe ngokuthe ngqo, kwanele ukwakha i-valve encinci yesandla kakuhle.Kwiindlela eziqhelekileyo, azikwazi ukungcwatywa ngokuthe ngqo, kwaye kufuneka kwakhiwe amaqula amakhulu e-valve, okubangela ukuba kubekho indawo evaliweyo eyingozi, engafanelekanga ekusebenzeni okukhuselekileyo.Kwangaxeshanye, umzimba wevalve ngokwawo kunye neendawo zokuqhagamshelwa kwebholithi phakathi komzimba wevalve kunye nombhobho ziya konakala, nto leyo eya kuchaphazela ubomi benkonzo yevalve.

Yintoni ekufuneka ithathelwe ingqalelo ekugcinweni kwevalve yebhola edityanisiweyo ngokupheleleyo?

Ingongoma kukuba kwimeko evaliweyo, kusekho ulwelo olucinezelekileyo ngaphakathi kumzimba wevalve.

Inqaku lesibini lelokuba phambi kokugcinwa, qala ngokukhulula uxinzelelo lombhobho emva koko ugcine ivalve kwindawo evulekileyo, emva koko unqumle amandla okanye umthombo werhasi, emva koko ukhuphe i-actuator kwisibiyeli, kwaye emva kokuba konke oku kungentla kunokulungiswa. .

Inqaku lesithathu kukufumanisa ukuba uxinzelelo lwemibhobho ephuma phezulu nasezantsi yevalve yebhola iyakhululeka, emva koko ukuqhawuka kunye nokubola kunokwenziwa.

Amanqaku amane kufuneka alumke kwinkqubo yokuqhawula kunye nokuhlanganisa kwakhona, ukukhusela umonakalo kwindawo yokutywinwa yamacandelo, ukusebenzisa izixhobo ezikhethekileyo zokususa i-O-ring, kunye nokuqinisa iibholithi kwi-flange ngokulinganayo kwaye ngokuthe ngcembe kwaye ngokulinganayo. ngexesha lendibano.

Amanqaku amahlanu: Xa ucoca, i-ejenti yokucoca esetyenzisiweyo kufuneka ihambelane neendawo zerabha, iiplastiki, iindawo zetsimbi kunye nokusebenza okuphakathi kwi-valve yebhola.Xa i-medium yokusebenza i-gas, i-petroli ingasetyenziselwa ukucoca iindawo zetsimbi, kunye ne-non-metallic parts, kufuneka usebenzise amanzi acocekileyo okanye utywala ukucoca.Iindawo ezibolileyo zicocwa ngokuntywiliselwa, kwaye iindawo zentsimbi zamalungu angengo-metal angaboliswanga ayakhuhlwa ngelaphu lesilika elicocekileyo nelicolekileyo elifakwe kwi-agent yokucoca, kwaye onke amagrisi abambelele kumphezulu wodonga kufuneka ahlanjwe. isusiwe., ukungcola nothuli.Kwakhona, ayikwazi ukuhlanganiswa ngokukhawuleza emva kokucoca, kwaye inokuqhutywa kuphela emva kokuba i-arhente yokucoca iphelile.
