Ngaphambi kokuba kufake ivalve, ukuncitshiswa kwe-valve kunye novavanyo lwe-valve kufuneka lwenziwe kwibhentshi yovavanyo lweValve Hydraulic. Iipesenti ezingama-20 ze-valve zoxinzelelo eziphantsi kufuneka zihlolwe ngokungacwangciswanga, kwaye i-100% kufuneka ihlolwe ukuba ayinakho ukwenziwa; Iipesenti eziyi-100 ze-valve eziphakathi kunye nexabiso eliphezulu kufuneka zihlolwe. Izinto eziqhelekileyo ezisetyenziswayo zovavanyo lwexabiso le-valve ngamanzi, ioyile, umoya, i-shoam, i-nitrogen, njl njl.
Indlela yebhabhathane yovavanyo
Uvavanyo lwamandla lwebhabhathane ye-pneumatic vatve verve ngokufana ne-valve yeglove. Kuvavanyo lokutywina kwendawo yokutywina yebhabhathane, iprinta yovavanyo kufuneka ingeniswe kwisiphelo sokuhamba kwephakathi, ipleyiti yebhabhathane kufuneka ivulwe, kwaye esinye isiphelo kufuneka sifike kwixabiso elichaziweyo; Emva kokujonga ukuba akukho mvundla ekupakisheni kunye nezinye izitywina, vala iplate yebhabhathane, vula esinye isiphelo, kwaye ujonge ivalve yebhabhathane. Akukho vuselelo kwitywina leplate lifanelekile. I-Butterfly Valve esetyenziselwa ukulawula ukuhamba akunakuvavanywa ukusebenza kokutywina.
Uvavanyo lovavanyo lwendlela yokujonga i-valve
Ukujonga uvavanyo lweValve: I-Axis ye-Sokhi yokuphakamisa i-Valve ikwindawo ye-Polve ikwisikhundla esijikelezayo; I-axis ye-swing valnel yecandelo yeValve kunye ne-disc i-axis ikwindawo emalunga nomgca othe tyaba.
Ngexesha lovavanyo lwamandla, i-ofisi yovavanyo ingeniswa ukusuka kwi-inlet kwixabiso elichaziweyo, kwaye esinye isiphelo sivaliwe, kwaye kuyakufanelekela ukubona ukuba i-valve ivele kunye ne-valve ingenamali.
Kuvavanyo lokutywina, i-ofisi yovavanyo ingeniswa kwisiphelo sokuphuma, kwaye umphezulu wokutywina ujongiwe kwisiphelo se-Inlet, kwaye akukho vumo lokupakisha kwaye i-gasket ifanelekile.
Indlela yovavanyo loxinzelelo lwe-valve yesango
Ukuvavanywa kwamandla kwelanga kwesango kuyafana nebhobho yeglove. Zimbini iindlela zovavanyo oluqinileyo lwevalve yesango.
①Vula isango ukuze wenze uxinzelelo kwi-valve linyuke liye kwixabiso elichaziweyo; Emva koko vala isango, susa i-valve yesango kwangoko, jonga ukuba i-akages i-Tought kwi-Palve kwixabiso elichaziweyo, jonga amatywina kumacala omabini esango. Le ndlela ingentla ibizwa kuvavanyo oluPhakathi kuvavanyo oluPhakathi. Le ndlela ayifanele isetyenziselwe uvavanyo lokutywina kwi-valve yesango kunye ne-DN32mmm.
②Enye indlela kukuvula isango ukwenza uvavanyo lweValve lunyuke kwixabiso elichaziweyo; Emva koko vala isango, vula isiphelo esinye seplate engaboniyo, kwaye ujonge ukuba umhlaba wokutywina uvuza. Emva koko buyela emva kwaye uphinde loluphi uvavanyo olungentla de luqiniseke.
Uvavanyo lokuthoba lokupakisha kunye ne-gasket ye-Poaumatic Palve yesango lePneumatic iya kwenziwa ngaphambi kovavanyo lokuqina kwesango.
Uxinzelelo lovavanyo loxinzelelo lokunciphisa ivalve
①Uvavanyo lwamandla lwevali yokunciphisa uxinzelelo luhlanganisene ngokubanzi emva kovavanyo lwesiqwengana, kwaye unokuvavanywa emva kwendibano. Ixesha lokuvavanywa kwamandla: 1min ye-DN <50mm; ngaphezulu kwe-2min ye-DN65~I-150mm; ngaphezulu kwe-3min ye-DN> 150mm.
Emva kokuba i-bulbles kunye nezinto ziyafakwa, faka izihlandlo ezi-1.5 zoxinzelelo oluphezulu lwevali yokunciphisa uxinzelelo, kwaye wenze uvavanyo lwe-moya ngomoya.
②Uvavanyo lomoya luya kwenziwa ngokweyona nyani iphakathi. Xa uvavanywa ngomoya okanye amanzi, uvavanyo malunga ne-1.1 amaxesha oxinzelelo oluchanekileyo; Xa kuvavanywa i-Steam, sebenzisa uxinzelelo lomsebenzi oluvunyelweyo phantsi kobushushu bokusebenza. Umahluko phakathi kwengcinezelo ye-inlet kunye noxinzelelo lokuphuma lwe-Outlet luyafuneka ukuba ungabi ngaphantsi kwe-0.2MPA. Indlela yovavanyo yile: Kwindawo yokufumana uxinzelelo lwe-STEAM, xa uxinzelelo lwe-inlet luhlengahlengiswa, ivalve ivaliwe emva kokuba ivalve ivaliwe, kwaye uxinzelelo oluphezulu yeyona nto iphakamileyo nephantsi. Kwisithuba se-2min, ukwanda koxinzelelo lwedolophu kufuneka kuhlangabezane neemfuno zeTyentelo 4.176-22. Kwangelo xesha, umbhobho emva kwevalve kufuneka ibe ngumthamo weemfuno zeTyentelo 4.18 ukuze ulungele; Ukucutha uxinzelelo lwamanzi kunye noxinzelelo lomoya, xa uxinzelelo lwe-inlet lusetelwe kwaye uxinzelelo lwe-Outlet luvaliwe, ivalve encitshisiweyo ivaliwe kuvavanyo lokuqina, kwaye akukho vumo ngaphakathi kwemizuzu emi-2.
Indlela yovavanyo loXinzelelo lweNdwaba yeHlabathi kunye neHalvemple
Ngovavanyo lwamandla enkunkuma yehlabathi kunye ne-hardve ivalve, ivalve ehlanganisiweyo idla ngokuvulwa, i-valve ivuliwe, kwaye i-valve ifakwe kwixabiso le-valve kunye ne-valve kunye nokuvuza. Uvavanyo lwamandla lunokwenziwa nakwisiqwengana esinye. Uvavanyo lokuqina kuphela kwivalve evaliweyo. Ngexesha lovavanyo, i-valve stem ye-valve ikwimo ethe nkqo, idiski ye-valve ivuliwe, i-varium izihlandlo ezivela kwisiphelo se-valve kwixabiso le-valve kwixabiso elichaziweyo, kwaye i-gasket ijongiwe; Emva kokuphumelela uvavanyo, i-valve disve ivaliwe, kwaye esinye isiphelo sivulwa ukuba sijonge ukuba ngaba kukho ukuvuza. Ukuba amandla kunye novavanyo lokuqina kufuneka lwenziwe, uvavanyo lwamandla lunokuncitshiswa kuqala, emva koko uxinzelelo luncitshisiwe kwixabiso elichaziweyo lovavanyo lokuqina, kwaye ipakethi kunye ne-gasket ijongiwe; Emva koko i-disfu ye-valve ivaliwe, kwaye isiphelo se-Outlet siyavulwa ukuba indawo yokutywina ivuza.
Indlela yovavanyo lwe-Halve Palve
Uvavanyo lwamandla kwi-valve yebhola ye-pneumatic kufuneka yenziwe kwi-valty evulekileyo ye-valve yebhola.
①Uvavanyo lokudada i-Valve Paling Paling: Beka i-valve kwi-cinder-gesi ovulekileyo, yazise uvavanyo oluthile kwelinye icala, kwaye lusondele kwesinye isiphelo; Jikelezisa ibhola izihlandlo ezininzi, vula isiphelo esivaliweyo xa ivalve isemoyeni evaliweyo, kwaye ijonge ukusebenza ngokutywina kwipakethi kunye negasket ngexesha elinye. Akufanelanga ukuba kungabikho nto. Uvavanyo lwendlela emva koko lwaziswa ukusuka kwelinye icala kwaye lovavanyo lungentla luphindwe.
②Uvavanyo lokutywina kwe-valve yebhola esisigxina: ngaphambi kovavanyo, jikeleza ibhola ngaphandle komthwalo, ivalve yebhola emiselweyo ikwimeko evaliweyo, kwaye i-valve yovavanyo ingeniswa ukusuka kwixabiso elichaziweyo; Intsebenzo yokutywina kwesiphelo sentshayelelo itshekishwe ngegeji yoxinzelelo, kunye nokuchaneka kwe-gauge yoxinzelelo kungu-0 .5 ukuya kwi-1, uluhlu luyi-1.6 amaxesha oxinzelelo lovavanyo. Ngexesha elichaziweyo, ukuba akukho nto ingekhoyo i-tytomenon, ifanelekile; Emva koko wazisa uvavanyo oluvela kwelinye icala, kwaye uphinde loluphi olu vavanyo lungentla. Emva koko, faka i-valve kwi-velve evulekileyo, vala zombini iziphelo, kwaye ugcwalise umngxunya wangaphakathi kunye nephakathi. Jonga ukupakisha kunye ne-gasket phantsi koxinzelelo lovavanyo, kwaye akufuneki ukuba kungabikho nto.
③I-valve yeendlela ezintathu ziya kuvavanywa ngokuqina kwisikhundla ngasinye.
