3. Ukunciphisa uxinzeleloivalvuindlela yokuvavanya uxinzelelo

① Uvavanyo lwamandla evalvu yokunciphisa uxinzelelo ludla ngokuhlanganiswa emva kovavanyo olunye, kwaye lunokuhlanganiswa emva kovavanyo. Ubude bovavanyo lwamandla: 1 min ene-DN<50mm; DN65 ~ 150mm ubude kune-2min; Ukuba i-DN inkulu kune-150mm, inde kune-3min. Emva kokuba i-bellows idityaniswe kwizinto, uxinzelelo oluphindwe kayi-1.5 emva kokuba ivalvu yokunciphisa uxinzelelo ifakiwe, kwaye uvavanyo lwamandla lwenziwa ngomoya.
② Uvavanyo lokuqina lwenziwa ngokwendlela yokusebenza yokwenyani. Xa kuvavanywa ngomoya okanye ngamanzi, uvavanyo lwenziwa ngokuphindwe kayi-1.1 koxinzelelo oluqhelekileyo; Xa kuvavanywa ngomphunga, lwenziwa ngoxinzelelo oluphezulu oluvumelekileyo lokusebenza kubushushu bokusebenza. Umahluko phakathi koxinzelelo lokungena kunye noxinzelelo lokukhupha akufuneki ube ngaphantsi kwe-0.2MPa. Indlela yovavanyo yile ilandelayo: emva kokuba uxinzelelo lokungena lulungisiwe, isikrufu sokulungisa sevalvu sihlengahlengiswa kancinci kancinci ukuze uxinzelelo lokukhupha lutshintsheke ngokubonakalayo nangokuqhubekayo ngaphakathi koluhlu lwexabiso eliphezulu nelincinci, ngaphandle kokuma nokuvaleka. Kwivalvu yokunciphisa uxinzelelo lomphunga, xa uxinzelelo lokungena lususiwe, ivalvu ivaliwe kwaye emva koko ivalvu iyanqunyulwa, kwaye uxinzelelo lokukhupha luxabiso eliphezulu neliphantsi. Kwimizuzu emi-2, uxabiso loxinzelelo lokukhupha kufuneka luhambelane nemigaqo. Kwiivalvu zokunciphisa uxinzelelo lwamanzi nomoya, xa uxinzelelo lokungena luhlengahlengiswa kwaye uxinzelelo lokukhupha luyi-zero, ivalvu yokunciphisa uxinzelelo ivaliwe ukuze kuvavanywe ukutywinwa, kwaye akukho kuvuza ngaphakathi kwemizuzu emi-2 kuyafaneleka.

4. Ivalvu yebhabhathaneindlela yokuvavanya uxinzelelo

Uvavanyo lwamandla evalvu yebhabhathane ephefumulayo lufana nolwevalvu yeglobe. Uvavanyo lokusebenza kwevalvu yebhabhathane kufuneka lungenise isixhobo sokuvavanya ukusuka kwisiphelo sokungena, ipleyiti yebhabhathane mayivulwe, elinye icala livalwe, kwaye uxinzelelo lwenaliti lufanele lufikelele kwixabiso elichaziweyo; Emva kokujonga ukuba akukho kuvuza kwipakeji nakwezinye izitywino, vala ipleyiti yebhabhathane, vula elinye icala, kwaye ujonge ukuba akukho kuvuza kwitywina lepleyiti yebhabhathane. Iivalvu zebhabhathane ezisetyenziselwa ukulawula ukuhamba kwamanzi azenzi uvavanyo lokusebenza kwetywina.

5.Ivalvu yeplagiindlela yokuvavanya uxinzelelo
①Xa ivalvu yeplagi ivavanywa amandla, i-medium ingeniswa ukusuka kwelinye icala, yonke indlela ivaliwe, kwaye iplagi ijikeleziswa kwindawo yokusebenza evulekileyo ngokupheleleyo ukuze kuvavanywe, kwaye umzimba wevalvu awufumaneki uvuza.
② Kuvavanyo lokutywina, i-straight-through cock kufuneka igcine uxinzelelo olukwi-cavity lulingana ne-passage, ijikelezise i-plug iye kwindawo evaliweyo, ijonge ukusuka kwelinye icala, ize ijikelezise i-plug nge-180° ukuze iphinde uvavanyo olungasentla; I-valve ye-plug eneendlela ezintathu okanye ezine kufuneka igcine uxinzelelo olukwi-cavity lulingana nesinye isiphelo se-passage, ijikelezise i-plug iye kwindawo evaliweyo, ingenise uxinzelelo oluvela kwi-Angle end yasekunene, kwaye ijonge elinye icala ngaxeshanye.
Ngaphambi kovavanyo lwevalvu yeplagi, kuvumelekile ukufaka umaleko weoyile yokuthambisa engenanto ye-asidi kumphezulu wokuvala, kwaye akukho kuvuza kunye namaconsi amanzi akhulisiweyo afunyanwayo ngaphakathi kwexesha elichaziweyo. Ixesha lovavanyo lwevalvu yeplagi linokuba lifutshane, ngokubanzi lichazwe njenge-l ~ 3min ngokobubanzi obuqhelekileyo.
Ivalvu yeplagi yegesi kufuneka ivavanywe ukuba ayingeni moya na ngokuphindwe kayi-1.25 kunoxinzelelo olusebenzayo.

6.Ivalvu ye-diaphragmindlela yokuvavanya uxinzelelo

Uvavanyo lwamandla evalvu yediaphragm luzisa i-medium ukusuka nakweyiphi na isiphelo, luvule idiski yevalvu, luze luvale elinye icala. Emva kokuba uxinzelelo lovavanyo lunyuke luye kwixabiso elichaziweyo, kuyafaneleka ukubona ukuba umzimba wevalvu kunye nesigqubuthelo sevalvu azinawo amanzi avuzayo. Emva koko yehlisa uxinzelelo luye kuxinzelelo lovavanyo lokuqina, uvale idiski yevalvu, uvule elinye icala ukuze uhlolwe, akukho manzi avuzayo afanelekileyo.

7.Ivalvu yokumisakwayeivalvu yokuqhoboshaindlela yokuvavanya uxinzelelo
Uvavanyo lwamandla lwevalvu yeglobe kunye nevalvu ye-throttle ludla ngokubeka ivalvu edibeneyo kwi-rack yovavanyo loxinzelelo, ivule idiski yevalvu, ifake i-medium kwixabiso elichaziweyo, kwaye ijonge ukuba umzimba wevalvu kunye nesigqubuthelo sevalvu ziyabila kwaye ziyavuza na. Uvavanyo lwamandla lunokwenziwa ngokwahlukeneyo. Uvavanyo lokuqina lwenzelwe kuphela ivalvu yokumisa. Ngexesha lovavanyo, isiqu sevalvu yokumisa sikwimeko ethe nkqo, idiski yevalvu iyavulwa, i-medium ingeniswa ukusuka esiphelweni esisezantsi sediski yevalvu ukuya kwixabiso elichaziweyo, kwaye ukupakisha kunye negasket kuyajongwa. Xa kufanelekile, vala idiski yevalvu kwaye uvule elinye icala ukujonga ukuba kukho ukuvuza na. Ukuba uvavanyo lwamandla kunye nokuqina kwevalvu luza kwenziwa, uvavanyo lwamandla lungenziwa kuqala, kwaye emva koko uxinzelelo luyancitshiswa ukuya kwixabiso elichaziweyo lovavanyo lokuqina, kwaye ukupakisha kunye negasket kuyajongwa. Emva koko vala idiski yevalvu, vula isiphelo sokuphuma ukuze ujonge ukuba umphezulu wokutywina uyavuza na.
