Ivalve eneziqwenga eziNtathu zeBhola

1. Isishwankathelo sevalve yebhola enamacandelo amathathu

Njengohlobo lwevalve esetyenziswa ngokuqhelekileyo, iivalve zebhola zisetyenziswa ngokubanzi kwi-petroleum, imboni yeekhemikhali, amandla ombane, i-metallurgy kunye nezinye iindawo ngenxa yesakhiwo sabo esilula, ukusebenza kakuhle kokutywinwa, umthamo omkhulu wokuhamba, kunye nokuvulwa ngokukhawuleza kunye nokuvala. Iivalvu zebhola zinokwahlulwa zibe ziqhagamshelo ezinemisonto, uqhagamshelo lweflange, udibaniso olubambeneyo, njl.njl ngokwendlela yoqhagamshelo. Phakathi kwabo, i-valve yebhola edibeneyo ene-flange eneziqwenga ezintathu ineenzuzo ezibalulekileyo ekuqinisekiseni ukutywinwa kwenkqubo kunye nokuthembeka kunye noyilo olukhethekileyo lwesakhiwo.

2. Iimpawu zesakhiwo se-valve yebhola yamacandelo amathathu

2.1. Ulwakhiwo olunamacandelo amathathu: Ivalve yebhola eneziqwenga ezintathu inamalungu amathathu: umzimba wevalvu, ibhola kunye nesitulo sevalvu. Olu yilo lwesakhiwo lwenza ukuba i-valve ibe lula ngakumbi ngexesha lofakelo kunye nokugcinwa. Ibhola kunye nesihlalo sevalve ziqhagamshelwe ngokuguquguqukayo ukuze kube lula ukuqhawula kunye nokutshintshwa.

2.2. Uxhulumaniso lweFlange: Indlela yokudibanisa i-flange ineenzuzo zokufakela lula, ukusebenza kakuhle kokutywinwa, kunye noluhlu olubanzi lwesicelo, kwaye inokufikelela kwiimfuno zoqhagamshelwano phantsi kweemeko ezahlukeneyo zokusebenza.

2.3. Isitywina sentsimbi: Ivalve yebhola eneziqwenga ezintathu ithatha isitywina sesinyithi, esinokumelana nokunxiba kakuhle, ukumelana noxinzelelo kunye nokumelana nobushushu obuphezulu, kuphucula ngokufanelekileyo ukusebenza kokutywinwa kunye nobomi benkonzo yevalve.

2.4. Umsesane wokutywina wesihlalo sevalve: Umsesane wokutywina wesitulo sevalve wamkela i-O-ring okanye i-V-ring, enokweluka okulungileyo kunye nokusebenza kokuzitywina kwaye inokubuyisela ngokuzenzekelayo ukunxitywa phakathi kwesitulo sevalve kunye nebhola ukuqinisekisa ukutywinwa kwexesha elide ivalve.

2.5. Ukutywinwa kweendlela ezimbini: I-valve yebhola emithathu ithatha idizayini yokutywinwa kweendlela ezimbini, ezinokuthintela ukuvuza okuphakathi kunye nokukhusela i-medium yangaphandle ukuba ingene, iqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo.

3. Izinto eziluncedo kwiivalve zebhola ezintathu ekuphuculeni ukutywinwa kwenkqubo kunye nokuthembeka

3.1. Ukusebenza kokutywinwa okuphezulu: Ukudityaniswa kwesitywina sentsimbi kunye ne-elastic seal kwenza ukuba ivalve yebhola eneziqwenga ezintathu ibe nokusebenza kokutywinwa okuphezulu. Ngaphantsi kweemeko ezinzima zokusebenza ezifana noxinzelelo oluphezulu, ukushisa okuphezulu, ukubola okunamandla, njl., ukutywinwa okuthembekileyo kwevalve kusenokuqinisekiswa.

3.2. Ukusebenza okuchasene nokunxiba: Ibhola kunye nesitulo sevalvu zenziwe ngezinto ze-carbide, ezinokuxhathisa okuphezulu kakhulu. Ngethuba lokusetyenziswa kwexesha elide, inokumelana ngokufanelekileyo nokugqoka kwendawo ephakathi kunye nokwandisa ubomi benkonzo yevalve.

3.3. Ukuthembeka okuphezulu: I-valve yebhola emithathu inesakhiwo esilula, inani elincinci leenxalenye, kunye nezinga eliphantsi lokungaphumeleli. Kwangaxeshanye, isitywina sentsimbi kunye noyilo lwesitywina seendlela ezimbini zenza ivalve ithembeke ngakumbi ngexesha lokusebenza.

3.4. Ukuvulwa ngokukhawuleza kunye nokuvala: Isakhiwo sebhola se-valve yebhola sivumela i-valve ukuba ivule kwaye ivale ngokukhawuleza ngokujikeleza ngobumnene i-90 degrees ngexesha lokuvula kunye nokuvala inkqubo, ngokufanelekileyo ukunciphisa ukuguqulwa koxinzelelo lwenkqubo.

3.5. Kulula ukuyigcina: Idizayini yokudibanisa eguquguqukayo yevalve yebhola yebhola emithathu yenza ibhola kunye nesihlalo sevalve kube lula ukuchithwa kunye nokutshintsha, ukunciphisa iindleko zokugcina kunye nexesha lokuphumla.

4. Iimeko zesicelo

Ngexesha lenkqubo yemveliso, ishishini lepetrochemical kufuneka lilawule ubushushu obuphezulu, uxinzelelo oluphezulu, kunye nemithombo yeendaba eyonakalisa kakhulu. Emva kokuthelekisa ezininzi kunye neengxabano, inkampani yakhetha i-valve yebhola edibeneyo ye-flange edibeneyo. Kwizicelo ezisebenzayo, i-valve ibonisa ukusebenza kakuhle kokutywinwa, ukusebenza okuchasene nokunxiba kunye nokuthembeka, ukubonelela ngesiqinisekiso esiqinileyo kwimveliso ekhuselekileyo yenkampani.

Ngoyilo lwayo olukhethekileyo lwesakhiwo kunye nokusebenza okuphezulu, i-valve yebhola ye-flange edibeneyo emithathu ineenzuzo ezibalulekileyo ekuphuculeni ukutywinwa kunye nokuthembeka kwenkqubo yokulawula ulwelo. Ngokuqhubela phambili okuqhubekayo kweteknoloji, amathuba okusetyenziswa kweevalve zebhola ezintathu ziya kuba zibanzi kwixesha elizayo. Iinjineli kunye nokusebenza kwezixhobo kunye nabasebenzi bokulondoloza kufuneka baziqonde ngokupheleleyo iimpawu zayo zokusebenza kwaye benze ukhetho olufanelekileyo ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokuzinza kwenkqubo.
