Amabala esicelo amahlanu kunye noncedo lwemiyalelo yevalve yebhola engcwatyiweyo yevalve yebhola

Amabala esicelo amahlanu kunye noncedo lwemiyalelo yevalve yebhola engcwatyiweyo yevalve yebhola egcweleyo yombane we-welding yevalve yebhola yeentlobo ngeentlobo zezixhobo zoomatshini: umbhobho ohlukeneyo wenkqubo yonyango lobushushu, iintlobo ngeentlobo zemveliso yemizi-mveliso yerhasi enolwelo kunye nemibhobho yokufudumeza. Ivalve yebhola engcwatywe iplagi ephindwe kabini kunye nokukhupha sebenzisa isihlalo sokuguquguquka se-torsion spring torque, nokuba ivalve ikwimeko evulekileyo okanye evaliweyo, isihlalo esingaphezulu, esiphakathi kunye nesisezantsi somlambo senza umqobo wolwelo, ipleyiti yendlela yeoyile kwindawo yokugcinwa komngxuma ngokwevalve yokukhupha. imetabolism. Umphumo ozenzekelayo wokunciphisa uxinzelelo lwevalve yebhola engcwatyiweyo inokwenza ukuba ubushushu besixhobo sokugcina ityhubhu yezintso bunyuke kwaye bubangele utshintsho olungaqhelekanga loxinzelelo, ngaphandle kwesidingo sokuthembela kwivalve, kwaye umsebenzi wesihlalo unokuba ngokuzenzekelayo ukukhululeka koxinzelelo oluzenzekelayo, oya kuthi. qinisekisa ukhuseleko lwevalve ekuthuthweni kwezinto ezingamanzi kubaluleke kakhulu. I-1, ivalve yebhola ye-welding egcweleyo yombane yegesi yesixeko: umbhobho wokuthumela ngaphandle kwerhasi engamanzi, indlela enkulu kunye nombhobho wokubonelela ngesebe ngalinye, njl. njl. I-3, i-valve yebhola ye-welding epheleleyo yombane yokutshintsha ubushushu: umbhobho kunye ne-loop yokulawula ivule kwaye ivale. I-4, isinyibilikisi: zonke iintlobo zemibhobho yolwelo, umbhobho wokukhetha igesi ephuma kwizinto eziphilayo, igesi enolwelo kunye nombhobho wokubonelela ngokufudumeza, umbhobho wokubonelela ngamafutha. I-5, i-valve yebhola ye-welding egcweleyo yombane kwiintlobo zezixhobo zoomatshini: iindidi zemibhobho yenkqubo yokushisa ubushushu, imveliso eyahlukeneyo yemveliso yerhasi enolwelo kunye nemibhobho yokufudumeza. Ivalve yebhola engcwatywe iplagi ephindwe kabini kunye nokukhupha sebenzisa isihlalo sokuguquguquka se-torsion spring torque, nokuba ivalve ikwimeko evulekileyo okanye evaliweyo, isihlalo esingaphezulu, esiphakathi kunye nesisezantsi somlambo senza umqobo wolwelo, ipleyiti yendlela yeoyile kwindawo yokugcinwa komngxuma ngokwevalve yokukhupha. imetabolism. Umphumo ozenzekelayo wokunciphisa uxinzelelo lwevalve yebhola engcwatyiweyo inokwenza ukuba ubushushu besixhobo sokugcina ityhubhu yezintso bunyuke kwaye bubangele utshintsho olungaqhelekanga loxinzelelo, ngaphandle kwesidingo sokuthembela kwivalve, kwaye umsebenzi wesihlalo unokuba ngokuzenzekelayo ukukhululeka koxinzelelo oluzenzekelayo, oya kuthi. qinisekisa ukhuseleko lwevalve ekuthuthweni kwezinto ezingamanzi kubaluleke kakhulu. Izinto eziluncedo kwivalve yebhola engcwatyiweyo 1, ukutywinwa kokuhlangulwa kwegrisi kaxakeka: ngenxa yezinto ezimdaka kwizinto okanye iingozi zomlilo zikhokelela ekunganyanzekiyo okungalindelekanga kwesitulo sevalvu, ivalve yegrisi izisa unxibelelwano oludibeneyo kunye nenaliti yegrisi, impompo ethunyelwa ngaphandle igcina ixesha kwaye umzamo wokufaka igrisi yokutywina kwindawo yokutywina, ukunciphisa ukuvuza. 2. Ukutywinwa kwe-valve stem ethembekileyo kunye ne-torque ephezulu yokusebenza: ukongeza kwiseti yokutywinwa kwenkcazo, i-O-ring yongezwa kwi-packing screw cap, ukutywinwa kweendlela ezimbini kuqinisekisa ukuzinza kwe-valve stem ukutywinwa; Ukongezwa kokupakishwa kwegraphite ecocekileyo kunye nokutywinwa kwegrisi kwenza ukuvuza kwesiqu emva komlilo kusezantsi kakhulu. Iibheringi ze-Stem rolling kunye nee-thrust bearings zenza ukuba ivalve ibe lula ukusebenza. 3. Ubungakanani bombhobho ogcweleyo okanye ububanzi obuncitshisiweyo: Umbhobho ogcweleyo ogcweleyo okanye isakhiwo esincitshisiweyo sedayamitha singasetyenziselwa ngokweyona meko. I-diameter epheleleyo yokuhamba kwe-valve egcwele-i-diameter epheleleyo ihambelana nomlinganiselo oqingqiweyo wombhobho, ohambelana nokucoca imibhobho. I-4, i-valve stem inokwandiswa: ngokweemfuno zokuhlanganisa okanye ukusebenza, i-valve stem inokwandiswa. Ivalve yebhola yentonga eyandisiweyo, ilungele ngakumbi irhasi yasezidolophini kunye nezinye iindawo ezifuna ukugqwethwa ngqo kwimibhobho egangathiweyo. Ukwandiswa kwesikhondo sevalve njengoko kufunwa ngumthengi. 5. Kulula ukusebenza: isihlalo sevalve kunye ne-stem rolling bearing kunye nokumelana ne-friction encinci kunye ne-self-lubrication egqwesileyo ikhethwa ukunciphisa i-torque yokusebenza yevalve. Ke ngoko, iivalve zebhola ezingcwatyiweyo zinokusebenza ngokuguquguqukayo kwivalve ixesha elide nokuba aziboneleli ngokuthambisa ukutywina. Ivalve yolawulo lwezandla enerocker okanye igiya, ivalve yombane okanye yepneumatic yebhola eqhutywa sisixhobo sombane okanye isixhobo somoya, yenza ukujikeleziswa kwebhola 90. Vula okanye uvale ivalve. Isiqu sevalve yebhola eqhutywa ngesandla siphawulwe phezulu. I-azimuth ye-concave groove kunye nobude becala le-spinner kunye nesalathiso somzila wokuhamba sivulekile, kwaye ulwalathiso oluthe nkqo lokuhamba kwempahla luvaliwe. Ivalve yokugcina ixesha elide kufuneka igcinwe rhoqo, *** inkunkuma. Kufuneka ubeke ingqalelo ukucoca umphezulu, uthintele umonakalo womphezulu. Ngaphambi kokwakhiwa ukujonga umjelo wevalve kunye nomphezulu, ukuba kukho amabala, kufuneka ukhethe ukusula okucocekileyo. Inyathelo 1: Udidi Lo myalelo ubandakanya idiameter yegama DN15mm~500mm(1/2"~20"), idiameter yegama PN1.6MPa~10MPa(ANSI> 2. Usetyenziso oluphambili 2.1 Isitshixo sisetyenziselwa ukuvula okanye ukuvala imibhobho noomatshini. 2.2.1 Ivalve yentsimbi yekhabhoni ingasebenzisa amanzi, umphunga, idizili kunye nezinye izinto 130℃ PTFE glass fiber ≤160℃ PPL(admixture polystyrene)≤300℃ Inyathelo lesi-3: Isakhiwo 3.1 Iimpawu zesakhiwo sevalvu yebhola ziboniswe kuMfanekiso 1 3.2 Iindawo ezisetyenziswayo zokutywina iigaskithi, ukupakisha i-PTFE okanye igraphite eguquguqukayo, ethembekileyo41 Ivalve yolawulo lwezandla sebenzisa isixhobo serocker okanye igiya yokuhambisa, ivalve yombane okanye yepneumatic eqhutywa sisixhobo sombane okanye isixhobo somoya, ukuze ibhola ijikeleze 90. Vula okanye uvale ivalve 4.2 Umphezulu wevalve okroliweyo we-concave groove ulwalathiso olude lwe-spinner kunye nolwalathiso lwejelo lokuhamba luvulekile, kwaye ulwalathiso oluthe nkqo lokuhamba kwempahla luvaliwe. 4.3 Amanqaku okuvula nawokuvala eevalvu zebhola yombane neyepneumatic aphawulwa ngesalathi-nkqubela sendawo kwisixhobo sombane nakwisixhobo somoya. 5. Ukugcinwa, ukugcinwa, ukufakela kunye nokufaka isicelo 5.1 Ivalve kufuneka igcinwe kwigumbi elomileyo nelingena umoya. Amacala omabini endlela yokhuseleko yevalve kufuneka avalelwe. 5.2 Iivalvu zokugcina ixesha elide kufuneka zigcinwe rhoqo, inkunkuma. Kufuneka ubeke ingqalelo ukucoca umphezulu, uthintele umonakalo womphezulu. 5.3 Ngaphambi kokwakhiwa, khangela ngononophelo ukuba ngaba uphawu lwevalvu luyahambelana neemfuno zokusetyenziswa. 5.4 Phambi kokwakhiwa, jonga umjelo wevalvu kunye nomphezulu. Ukuba kukho amabala, zicoce ngeetawuli zokucoca. 5.5 Khangela ukuba ukupakishwa kuxinanisekile na phambi kokwakhiwa, kwaye uqinisekise ukuqina kokupakishwa. Ngelo xesha, ukujikeleza kwe-valve stem akunakuthintelwa. 5.6 Iivalvu kufuneka zibe kwindawo evuleke ngokupheleleyo ekugqityweni kofakelo lwesixokelelwano okanye uvavanyo lwe-hydrostatic yombhobho. 5.7 Ibhola kufuneka ivulwe okanye ivalwe phambi kokusetyenziswa, kwaye inxalenye yebhola mayingavulwa ukunyenyisa ivalve. 5.8 Kwinkqubo yokuvula okanye ukuvala i-valve ye-manual, i-rocker kufuneka isetyenziswe ukuyivula okanye ukuyivala, kunye ne-lever yokuncedisa imali okanye ezinye izixhobo akufanele zisetyenziswe. 5.9 Ukufakwa kweValve kufuneka kugcinwe rhoqo ukujonga ukuba ngaba akukho monakalo kumphezulu kunye nokupakishwa kwe-gasket. Ukuba umonakalo awusebenzi, kufuneka ulungiswe kwaye utshintshwe ngexesha. 5.10 Ngesistim yothumelo lweevalvu zombane nezepneumatic, nceda ujonge "I-Valve Electric Device Operation Manual" kunye "ne-Valve Pneumatic Device Operation Manual" ukulungiselela ukugcina, ukulondoloza, ukufakela kunye nesicelo.
