3. Ukunciphisa uxinzeleloivalveindlela yovavanyo loxinzelelo

① Uvavanyo lwamandla evalve yokunciphisa uxinzelelo ludityaniswa ngokubanzi emva kovavanyo olunye, kwaye lunokuhlanganiswa emva kovavanyo.Ubude bexesha lovavanyo lwamandla: 1min kunye ne-DN<50mm;DN65 ~ 150mm ubude kune-2min;Ukuba i-DN inkulu kune-150mm, inde kunemizuzu emi-3.Emva kokuba i-bellows idityaniswe kumacandelo, amaxesha angama-1.5 uxinzelelo oluphezulu emva kokuba i-valve yokunciphisa uxinzelelo isetyenziswe, kwaye uvavanyo lwamandla lwenziwa ngomoya.
② Uvavanyo lokuqina lwenziwa ngokweyona ndlela yokusebenza.Xa uvavanya ngomoya okanye ngamanzi, uvavanyo lwenziwa ngamaxesha angama-1.1 uxinzelelo lwegama;Xa uvavanya nge-steam, kuqhutyelwa kwingcinezelo ephezulu evumelekileyo yokusebenza kwiqondo lokushisa lokusebenza.Umahluko phakathi koxinzelelo lokungena kunye noxinzelelo lwe-outlet akufanele kube ngaphantsi kwe-0.2MPa.Indlela yokuvavanya ngolu hlobo lulandelayo: emva kokulungiswa koxinzelelo lwe-inlet, i-screw yokulungelelanisa i-valve ilungiswa ngokuthe ngcembe ukwenzela ukuba uxinzelelo lwe-outlet lube novelwano kwaye luguquke ngokuqhubekayo ngaphakathi koluhlu oluphezulu kunye nexabiso elincinci, ngaphandle kokumisa kunye nokuvalwa.Kwi-valve yokunciphisa uxinzelelo lwe-steam, xa uxinzelelo lwe-inlet lususiwe, i-valve ivaliwe kwaye i-valve iyanqunyulwa, kwaye uxinzelelo lwe-outlet luphezulu kwaye ixabiso eliphantsi.Kwimizuzu emi-2, ukuxatyiswa koxinzelelo lokuphuma kufuneka kuhambelane namalungiselelo.Kumanzi kunye noxinzelelo lomoya iivalve zokunciphisa, xa uxinzelelo lwe-inlet luhlengahlengiswa kwaye uxinzelelo lwe-outlet luyi-zero, i-valve yokunciphisa uxinzelelo ivalwe uvavanyo lokutywinwa, kwaye akukho kuvuza ngaphakathi kwemizuzu emi-2 ifanelekile.

4. Ivalve yebhabhathaneindlela yovavanyo loxinzelelo

Uvavanyo lwamandla evalve yebhabhathane yepneumatic luyafana nolwevalve yeglowubhu.Uvavanyo lokutywinwa kokusebenza kwevalve yebhabhathane kufuneka lwazise uvavanyo oluphakathi ukusuka ekupheleni kokungena, ipleyiti yebhabhathane kufuneka ivulwe, enye isiphelo kufuneka ivalwe, kwaye uxinzelelo lwenaliti kufuneka lufikelele kwixabiso elichaziweyo;Emva kokukhangela ukuba akukho kuvuza kwipakethe kunye namanye amatywina, vala ipleyiti yebhabhathane, uvule kwelinye icala, kwaye ujonge ukuba akukho kuvuza kwiplate yebhabhathane.Iivalvu zebhabhathane ezisetyenziselwa ulawulo lokuhamba azenzi uvavanyo lokusebenza lokutywina.

5.Ivalve yokuplagaindlela yovavanyo loxinzelelo
①Xa ivalve yeplagi ivavanyelwa ukomelela, okuphakathi kwaziswa ukusuka kwelinye icala, enye indlela ivaliwe, kwaye iplagi ijikeleziswa kwindawo evuleleke ngokupheleleyo yovavanyo, kwaye umzimba wevalve awufunyaniswa uvuza.
② Kuvavanyo lokutywinwa, iqhude elichanekileyo kufuneka ligcine uxinzelelo kwi-cavity elilingana ne-passage, ujikeleze iplagi kwindawo evaliweyo, khangela ukusuka kwelinye icala, uze ujikeleze iplagi 180 ° ukuphinda uvavanyo olungentla;I-valve yeplagi yeendlela ezintathu okanye ezine kufuneka igcine uxinzelelo kwi-cavity ilingana nesinye isiphelo sendlela, ujikeleze iplagi kwindawo evaliweyo ngokulandelelana, yazisa uxinzelelo olusuka kwi-Angle ekupheleni, kwaye ukhangele enye isiphelo. kwangelo xesha.
Ngaphambi kovavanyo lwe-valve yeplagi, kuvunyelwe ukusebenzisa umaleko we-oyile yokuthambisa i-non-acidic dilute kwindawo yokutywina, kwaye akukho kuvuza kunye namathontsi amanzi awandisiweyo afunyanwa ngaphakathi kwexesha elichaziweyo.Ixesha lovavanyo lwevalve yeplagi linokuba lifutshane, lichazwe ngokubanzi njenge l ~ 3min ngokwedayamitha yegama.
Ivalve yeplagi yegesi kufuneka ivavanyelwe ukuxinana komoya ngamaxesha angama-1.25 oxinzelelo lokusebenza.

6.Ivalve ye-diaphragmindlela yovavanyo loxinzelelo

Uvavanyo lwamandla evalvu ye-diaphragm lwazisa i-medium ukusuka nakweyiphi na isiphelo, ivula idiski yevalve, kwaye ivale esinye isiphelo.Emva kokuba uxinzelelo lovavanyo lukhuphukele kwixabiso elichaziweyo, lifanelekile ukubona ukuba umzimba wevalve kunye nesivalo sevalve ayinakuvuza.Emva koko unciphise uxinzelelo kuxinzelelo lovavanyo lokuqina, vala idiski yevalve, vula elinye icala ukuze lihlolwe, akukho kuvuza okufanelekileyo.

7.Ivalve yokumisakwayeivalve yomqalaindlela yovavanyo loxinzelelo
Uvavanyo lwamandla evalve yeglowubhu kunye nevalve ye-throttle idla ngokubeka ivalve edityanisiweyo kwindawo yovavanyo loxinzelelo, vula idiski yevalve, utofe okuphakathi ukuya kwixabiso elichaziweyo, kwaye ujonge ukuba umzimba wevalve kunye nesivalo sevalve ziyabila kwaye ziyavuza.Uvavanyo lwamandla lunokwenziwa ngabanye.Uvavanyo lokuqina lolwevalve yokumisa kuphela.Ngethuba lovavanyo, isiqu se-valve yokumisa sikwimeko ethe nkqo, i-disc ye-valve ivuliwe, i-medium yaziswa ukusuka ekupheleni kwe-disc ye-valve ukuya kwixabiso elichaziweyo, kwaye ukupakishwa kunye ne-gasket ihlolwe.Xa ufanelekile, vala idiskhi yevalve kwaye uvule esinye isiphelo ukujonga ukuba kukho ukuvuza.Ukuba uvavanyo lwe-valve kunye nokuqina kufuneka lwenziwe, uvavanyo lwamandla lunokwenziwa kuqala, kwaye ke uxinzelelo luyancitshiswa kwixabiso elichaziweyo lovavanyo lokuqina, kwaye ukupakishwa kunye ne-gasket kuhlolwe.Emva koko uvale idiski yevalve, vula isiphelo sendawo yokuphuma ukuze ukhangele ukuba ukuvuza komphezulu wokutywina kuyavuza.
