"Uhlalutyo lweenzuzo zokukhetha iivalve zokukhupha eziphezulu kunye nezisezantsi kwi-powder kunye ne-particle processing"

I-Abstract: Ukukhethwa kweevalve zokukhupha kubalulekile kwinkqubo yomgubo kunye nokulungiswa kwamasuntswana. Eli nqaku liza kuqhuba uhlalutyo olunzulu lokusebenzisa i-valve yokukhupha i-powder kunye ne-particle ephantsi, ihlolisise izibonelelo zabo, kwaye ibonelele ngolwazi olutsha kunye nokubhekisela kwimveliso ephathekayo.

1. Intshayelelo

I-powder kunye ne-particle yonyango yinxalenye ebalulekileyo yamashishini afana neekhemikhali, amayeza, kunye nokutya, kwaye umphumo wayo wonyango uchaphazela ngokuthe ngqo umgangatho kunye nokusebenza kakuhle kwemveliso. Njengesixhobo esibalulekileyo kwi-powder kunye neenkqubo zokucubungula amasuntswana, ukusebenza kunye nokukhethwa kweevalve zokukhupha kubaluleke kakhulu kuyo yonke inkqubo yokuvelisa. Okwangoku, kukho iindidi ezimbini eziqhelekileyo zokukhutshwa kweevalve kwimarike: ukunyuka phezulu nangaphantsi. Eli nqaku liza kuhlalutya iingenelo zezi zivalo zimbini zokukhupha kwiinkalo zesakhiwo, ukusebenza, kunye nokusetyenziswa.

I-2, Uhlalutyo lweeNgcebiso zeValve yokukhupha i-Expansion Upward

1. Iimpawu zesakhiwo

Ivalve yokukhupha isandisi esinyukayo ithatha idiski yevalve yokwandisa, kwaye isihlalo sevalve sisakhiwo esisicaba. Xa i-valve ivuliwe, i-disc ye-valve ityhila phezulu, kwaye i-gap phakathi kwe-disc ye-valve kunye nesihlalo se-valve yanda ngokuthe ngcembe, iququzelela ukuhamba kwepowder kunye ne-particle materials. Isakhiwo sayo silula, kulula ukuyifaka kunye nokugcina.

2. Ukusebenza okuhambayo

Umsantsa phakathi kwediski yevalve kunye nesihlalo sevalve yevalve yokukhupha ephezulu inokulungiswa ngokweemfuno zangempela, ukuze ivalve ibe nokusebenza kakuhle kokuhamba kwiindawo ezahlukeneyo zokuvula. I-powder kunye nezixhobo ze-granular, i-valve yokukhupha phezulu inokufezekisa ukukhutshwa ngokukhawuleza kunye nokuhamba kakuhle, ukunciphisa ukuchasana kwenkqubo, kunye nokuphucula ukusebenza kakuhle kwemveliso.

3. Ukusebenza kokutywina

Ivalve yokukhupha eyongeziweyo ithatha isakhiwo sesihlalo sevalve esicaba, kunye nediski yevalve kunye nesitulo sevalvu zinxibelelana ngomgca, kunye nokusebenza kakuhle kokutywinwa. Xa i-valve ivaliwe, i-disc ye-valve ifakwe ngokuqinileyo kwisihlalo se-valve, ikhusela ngokufanelekileyo ukuvuza kwe powder kunye nezinto eziphathekayo kunye nokuqinisekisa ukusebenza kokutywinwa kwenkqubo.

4. Ubungakanani besicelo

Ivalve yokukhupha iphezulu ifanelekile kwizinto ezahlukeneyo ze powder kunye negranular, ezifana nomgubo kunye nezixhobo zegranular kumashishini afana neekhemikhali, amayeza kunye nokutya. Ukongeza, ivalve yokukhupha iphezulu ingasetyenziswa kwiimeko ezikhethekileyo zokusebenza ezifana nobushushu obuphezulu, uxinzelelo oluphezulu, kunye nokubola.

5. Kulula ukusebenza

I-valve yokukhupha phezulu ithatha i-manual, i-electric okanye i-pneumatic drive, ekulula ukuyisebenzisa kwaye inokufikelela kulawulo olukude. Ngexesha le-powder kunye ne-particle processing, abaqhubi banokuhlengahlengisa ukuvulwa kwe-valve ngokweemfuno zangempela ukuze bafezekise ulawulo oluchanekileyo.

3, Uhlalutyo lweenzuzo zevalve yokukhupha ezantsi eyandisiweyo

1. Iimpawu zesakhiwo

Ivalve yokukhupha ezantsi ithatha idiskhi yevalve yokwandisa ezantsi, kwaye isihlalo sevalve sisakhiwo esithambekileyo. Xa ivalve ivuliwe, i-disc yevalve ivuleleka ezantsi kwaye isithuba phakathi kwayo kunye nesitulo sevalve sikhula ngokuthe ngcembe. Xa kuthelekiswa ne-valve yokukhupha ukwanda, i-valve yokukhupha i-expansion expansion inesakhiwo esinzima ngakumbi.

2. Ukusebenza okuhambayo

Ulwakhiwo oluthambekileyo phakathi kwediski yevalve kunye nesihlalo sevalve yevalve yokukhuphela ezantsi ivumela ivalve ukuba ibe nokusebenza kakuhle kokuhamba kwiindawo ezahlukeneyo zokuvula. Ngomgubo kunye nezixhobo ze-granular, i-valve yokukhupha i-valve ehlayo inokufezekisa ukukhutshwa ngokukhawuleza kunye nokuhamba kakuhle, ukunciphisa ukuxhathisa inkqubo.

3. Ukusebenza kokutywina

Isakhiwo somphezulu esithambekele phakathi kwediski yevalve kunye nesihlalo sevalve yevalve yokukhupha isandisi esisezantsi siphucula ukusebenza kokutywinwa. Xa i-valve ivaliwe, i-disc ye-valve ifakwe ngokuqinileyo kwisitulo se-valve, ikhusela ngokufanelekileyo umgubo kunye nokuvuza kwezinto ze-particle.

4. Ubungakanani besicelo

I-valve yokukhupha i-valve ezantsi ifanelekile ukuphatha umgubo kunye nezixhobo ze-particle ezifuna ukusebenza kokutywinwa okuphezulu. Isakhiwo sayo esithambekele sinokuthintela ngokufanelekileyo ukuvuza kwezinto kunye nokuhlangabezana neemfuno zeemeko ezikhethekileyo zokusebenza.

5. Kulula ukusebenza

Ngokufana ne-valve yokukhupha phezulu, i-valve yokukhupha ezantsi inokuphinda iqhutywe ngesandla, ngombane, okanye i-pneumatically, okwenza kube lula ukusebenza kunye nokufezekisa ulawulo olukude.

4, Isishwankathelo

Isishwankathelo, i-valve yokukhupha phezulu nangaphantsi ineenzuzo zabo ezifanelekileyo kwi-powder kunye ne-particle processing. I-valve yokukhupha i-expansion upward inesakhiwo esilula, ukusebenza kakuhle kokuhamba kakuhle, kwaye ifanelekile kwiimeko ezahlukeneyo zokusebenza; I-valve yokukhupha i-valve ehlayo inomsebenzi ophezulu wokutywina kwaye ifanelekile kwiimeko ezifuna ukusebenza kokutywinwa okuphezulu. Kwimveliso yangempela, iivalve ezifanelekileyo zokukhupha kufuneka zikhethwe ngokusekelwe kwiimfuno ezithile kunye neemeko zokusebenza ukuze kuphuculwe ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso.

Eli nqaku linika uhlalutyo olunzulu lweenzuzo zokunyuka kunye nezantsi, ukubonelela ngolwazi olutsha kunye nereferensi yokukhethwa kwee-valve zokukhupha kwi-powder kunye ne-particle processing. Kwizicelo eziphathekayo, kuyimfuneko ukuqwalasela izinto ezifana neempawu zezinto eziphathekayo kunye nokusebenza kwezixhobo, kwaye uqwalasele ngokubanzi ukukhethwa kwee-valve zokukhupha ukuphumeza imveliso esebenzayo kunye nokuzinza.
