Indlela yokujongana nokuvuza kwevalve, izizathu ezihlanu kunye neendlela zokukunceda ukuba ujongane ngokulula nokuvuza kwevalve

Ukujongana njani nokuvuza kwevalve, izizathu ezihlanu kunye neendlela zokukunceda ukuba ujongane ngokulula nokuvuza kwevalve Ukuvuza kweValve yinto ecaphukisayo kuye wonke umthengi. Nje ukuba kuvuzeke, kudla ngokubangela ukuba umsebenzi ungaqhutywa ngokwesiqhelo kwixesha elizayo. Kuyimfuneko ukuyisombulula ngokukhawuleza. NJENGEVALIVI ivelisa izizathu ezihlanu kunye neendlela zokukunceda ukuba uphathe ngokulula ukuvuza kwe-VALVE! Ukuvuza kwebhodi yesekethe yeoli kunye nevalve yokuqukuqela enye Isizathu: 1, ukuphosa intsimbi ukuphosa umgangatho awukho phezulu, ibhodi yesekethe yeoli kunye nomzimba omnye wevalve yokuhamba phezu komngxuma wesanti, indlela ekhululekileyo, ithumba le-welding kunye nezinye iintsilelo; 2, indawo yokugcina ebandayo iyaqhekeka; I-3, i-welding ayilungile, kukho amathumba e-welding, i-welding, iintanda zoxinzelelo lwangaphakathi kunye nezinye iintsilelo; 4. Ivalve yentsimbi yehagu yonakele emva kokungqubana nezinto ezijingayo. Iindlela zokuyigcina: 1. Ukuphucula umgangatho wokuphosa, uqhube uvavanyo lwamandla oxinzelelo ngokungqongqo ngokuhambelana nezibonelelo ngaphambi kokufakwa; 2, iqondo lobushushu kwi-0℃ kunye ne-0℃ ngaphakathi kwevalve, kufuneka iqhube ukugquma ubushushu okanye ubushushu, ivalve kufuneka isuswe yokugcina amanzi; 3. I-Welding yepleyiti yesekethe ye-oyile kunye ne-valve yokuhamba enye idityaniswe ne-welding yombane kufuneka iqhutywe ngokuhambelana nemithetho esebenzayo yokukhusela i-welding yombane, kunye nokufumanisa impazamo kunye novavanyo lwamandla oxinzelelo kufuneka luqhutywe emva kwe-welding; Imfundo yenkcubeko yeentaka yesebe HVAC uyilo Utitshala Du 4. Akuvumelekanga ngokungqongqo ukutyhala nokubeka izinto ezijingayo kwivalve, kwaye akuvumelekanga ukubetha intsimbi yehagu kunye neevalvu zezinto ezingezizo ezentsimbi ngehamile. Ukufakwa kwee-valve ezinkulu kufuneka kube nesakhelo sokuxhasa. Eyesibini, ukuvuza kokupakisha Ukuvezwa kwevalve, umlinganiselo wokuzalisa mkhulu. Isizathu: I-1, i-filler ayisetyenziswanga ngokuchanekileyo, ayinakumelana nokukhukuliseka kwezinto eziphathekayo, ayixhathisi kwi-valve yoxinzelelo oluphezulu okanye ipompo ye-vacuum, ubushushu obuphezulu okanye i-ultra-low-low application; I-2, ukufakela ukupakisha akuchanekanga, kukho amancinci endaweni enkulu, intloko yokudibanisa i-screw winding ayilungile, ikhululekile phantsi kokuqina kunye nezinye iintsilelo; 3, filler ngaphaya ubomi benkonzo, iye yaluphala, ukungabikho ductility; I-4, ukuchaneka kwe-valve stem ayiphezulu, ukugoba, ukukhukuliseka, umonakalo kunye nezinye iintsilelo; I-5, inani lamakhonkco okupakisha ayanele, i-gland ayinyanzelwanga; I-6, i-gland, iibholiti ze-anchor, kunye namanye amacandelo onakele, ukuze i-gland ingakwazi ukunyanzeliswa; I-7, ukusebenza kwangempela akunangqiqo, amandla amaninzi, njl.; 8, ukuthambeka kwedlala, umsantsa phakathi kwedlala kunye nesiqu mncinci kakhulu okanye mkhulu kakhulu, okukhokelela kumonakalo wesiqu, ukupakisha umonakalo. Izindlela zokulungisa: 1. Izinto eziluhlaza kunye neefom zokuzalisa kufuneka zisetyenziswe ngokwemiqathango yokusebenza eqhelekileyo; I-2, ngokweemfuno ezifanelekileyo zofakelo olufanelekileyo lokufakela, idiski kufuneka ibekwe ngeenxa zonke nge-clamping ejikelezayo, intloko yokudibanisa kufuneka ibe yi-30 ℃ okanye i-45 ℃; I-3, ubomi benkonzo bude kakhulu, ukuguga, ukupakisha okonakalisiweyo kufuneka kususwe ngokukhawuleza; I-4, ukugoba kwe-valve stem, umonakalo kufuneka uqondiswe, ukulungiswa, umonakalo omkhulu kufuneka ususwe ngokukhawuleza; I-5, ukupakishwa kufuneka kufakwe ngokuhambelana nenani elichaziweyo le-laps, i-gland kufuneka ibe yi-symmetrical kwaye iqinile, umkhono woxinzelelo kufuneka ube ne-gap ye-torque engaphezu kwe-5mm; I-6, i-gland eyonakalisiweyo, iibholiti ze-anchor kunye nezinye izinto, kufuneka zilungiswe okanye zisuswe ngokukhawuleza; I-7, kufuneka ilandele imigaqo yokusebenza yokhuseleko, ngaphandle kwe-spindle yohlobo lokungqubuzana, kunye nesantya esiqhelekileyo sokusebenza kokwenene kwamandla; I-8, kufuneka i-symmetrical kunye ne-symmetrical yokuqinisa i-anchor bolt ye-gland, i-gland kunye ne-stem gap incinci kakhulu, kangangoko kunokwenzeka ukwandisa i-gap; Ukususwa kwedlala kunye nesiqu kukhulu kakhulu, kufuneka kususwe. Ezintathu, ukuvuza okuphumayo Isizathu: 1, umphezulu wokugaya ungalingani, awukwazi ukuvelisa umgca osondeleyo; I-2, i-valve stem kunye neendawo ezivaliweyo zeziko lokudibanisa elijinga emoyeni, lijike okanye lonakaliswe; I-3, i-valve stem igobile okanye i-skew yokufakela, ukwenzela ukuba iindawo ezivaliweyo zithintele okanye zingahlangani phakathi; I-4, umgangatho wezinto eziphathekayo awukho ngqiqweni okanye awukho ngokwesimo sokusebenza kwevalve eqhelekileyo. Iindlela zogcino: 1, ngokweemeko zokusebenza zomgangatho ofanelekileyo wokusetyenziswa kwe-British gasket izinto ezikrwada kunye nefom; 2, uhlengahlengiso ngononophelo, uzinzile ukusebenza kwangempela; I-3, iibholiti ze-anchor kufuneka zibe ne-symmetrical kunye ne-symmetrical, kunye ne-torque wrench kufuneka isetyenziswe xa kuyimfuneko. Amandla okuqinisa kwangaphambili kufuneka ahlangabezane neemfuno, kungekhona enkulu kakhulu okanye encinci. I-flange kunye ne-flange uxhumano kufuneka ibe ne-gap ethile ye-torque; I-4, ukufakwa kwe-gasket kufuneka kuhlangane nokulungelelaniswa okuphakathi, ukuthwala amandla okulinganayo, ii-gaskets azivumelekanga ukuba zifake i-rebar lap kunye nokusetyenziswa kwee-gaskets ezimbini; I-5, ukhukuliseko lwe-static oluphumayo, imveliso yomonakalo kunye nokulungiswa, umgangatho wokucubungula awuphezulu, kufuneka uqhube ukugcinwa, ukugaya, ukuhlolwa kombala, ukwenza umphezulu we-static ophumayo ngokuhambelana nezibonelelo ezifanelekileyo; I-6, xa ufaka i-washer, nikela ingqalelo ekucoceni, usebenzisa i-petroli ukucima umphezulu, kwaye i-washer ayikwazi ukuwa. Isine, ukuvuza kwekhonkco lomsesane wokutywina Isizathu: 1. Umsesane wokutywina awucinezelwa ngokuqinileyo; 2, umsesane wokutywina kunye ne-welding ngokwayo, umgangatho we-welding wokutshiza umbi; 3, ikhonkco lokutywina umsonto wangaphandle, isikrufu, umsesane woxinzelelo olukhululekile; 4. Umsesane wokutywina udibaniswe kwaye ukhukuliswe. Iindlela zokuyigcina: I-1, i-sealant kufuneka ifakwe ekuvuzeni kokutywinwa kokutywinwa kwaye emva koko i-rolling ingaguquki; 2. Umsesane wokutywina uya kuphinda udityaniswe ngokomgangatho wokuwelda. Ukutshiza ukuwelda ayinakulungiswa kwi welding yokuqala yokutshiza kunye nokusetyenzwa kwemveliso; 3. Susa i-screws, uhlambulule ikhonkco loxinzelelo, ususe kwaye ubeke indawo yezinto ezonakalisiweyo, ugaye indawo yokutywina kunye nesihlalo sokudibanisa, kwaye udibanise kwakhona. Amacandelo anomonakalo omkhulu wokhukuliseko unokulungiswa nge-welding okanye i-bonding. I-4, indawo yokudibanisa ikhonkco yokutywina i-corrod, inokulungiswa ngokusila, ukudibanisa kunye nezinye iindlela, ayikwazi ukulungiswa kufuneka isuswe xa ikhonkco lokutywinwa. Isihlanu, cima iqhekeza lawa phantsi ukuze libangele ukuvuza Isizathu: 1, ukusebenza kwangempela akulunganga, ukuze iindawo ezivaliweyo zixinge okanye ngaphaya kwendawo ephezulu yokufa, uxhulumaniso lonakaliswe kwaye lwaphukile; 2, cima unxibelelwano aluqinanga, lukhulule kwaye luwele phantsi; I-3, izinto zokudibanisa azichanekanga, azikwazi ukumelana nokubola kwezinto kunye nomonakalo wezixhobo zoomatshini. Izindlela zokulungisa: I-1, ukusebenza okusebenzayo okufanelekileyo, ukuvala i-valve ayinakomelela kakhulu, vula i-valve ayinakuba phezulu kunendawo efileyo ephezulu, emva kokuba i-valve ivulwe ngokupheleleyo, i-spindle kufuneka iguqule inani elincinci; 2. Ukudibanisa phakathi kwendawo yokuvala kunye ne-valve stem kufuneka iqine, kwaye i-flange uxhumano kufuneka ibe nenxalenye yokubuyisela; I-3, iindawo eziqhelekileyo ezidityaniswe ne-valve stem kufuneka zimelane nokukhukuliseka kwezinto, kwaye zibe nefuthe elithile lokuqina kunye nokumelana nokunxiba.
