I-Pneumatic Welded Ama-Ball Valves-Piece Three: Athembekile Ezimeni Ezinzima

Isakhiwo esimangelengele, izinga lokushisa eliphezulu kanye nokumelana nokucindezela okukhulu: Ukuhlolwa okujulile kokwethembeka kwamavalvu ebhola aneziqephu ezintathu zepneumatic ashiselwe ngaphansi kwezimo zokusebenza ezinzima.

Okufingqiwe: Ezinhlelweni eziningi zezimboni, ama-valve ebhola ahehe ukunaka okusabalele ngokusebenza kwawo okuhle kakhulu kokuvala nezici zokulawula uketshezi. Leli phepha lenza ukuhlola okujulile kokwethembeka kwamavalvu ebhola aneziqephu ezintathu ze-pneumatic welded ngaphansi kwezimo ezinzima zokusebenza, futhi lihlola izinzuzo zalo kanye namathemba okusebenza endaweni yokushisa ephezulu kanye nengcindezi ephezulu ngokuhlaziywa kwesakhiwo sayo, izinto zokwakha kanye nokusebenza.

1. Isingeniso

Ngokuthuthuka okuqhubekayo kobuchwepheshe bokukhiqiza ezimbonini, izidingo zemishini yokulawula uketshezi ziya ngokuya ziba phezulu. Emkhakheni we-petroleum, imboni yamakhemikhali, amandla kagesi, njll., izinga lokushisa eliphezulu kanye nezimo zokusebenza ezicindezelayo kubangela izinselele ezinzima ekusebenzeni kwemishini ye-valve. Njengomkhiqizo we-valve osetshenziswa kakhulu ezimeni zokusebenza ezinzima, ukwethembeka kwamavalvu ebhola aneziqephu ezintathu ze-pneumatic ashiselwe sekugxilwe ekunakeni konjiniyela kanye nabasebenzi bezobuchwepheshe. Leli phepha lizokwenza ukuhlola okuningiliziwe kokuthembeka kwama-valve e-pneumatic welded amabhola amathathu ngaphansi kwezinga lokushisa eliphezulu kanye nezindawo ezicindezelayo ezivela ezicini zesakhiwo, izinto zokwakha kanye nokusebenza.

2. Izici zesakhiwo se-pneumatic welded ama-valve amabhola amathathu

2-1. Idizayini yesakhiwo esineziqephu ezintathu

I-valve ye-pneumatic welded yebhola eneziqephu ezintathu yamukela ukwakheka kwesakhiwo esinezingcezu ezintathu, esilungele ukuhlakazwa nokugcinwa kwe-valve. Emazingeni okushisa aphezulu kanye nemvelo yokucindezela okukhulu, lo mklamo unciphisa ngokuphumelelayo ukuhlushwa kokucindezeleka okubangelwa ukushintsha kwezinga lokushisa ku-valve, futhi kuthuthukisa amandla onke nokuthembeka kwe-valve.

2-2. Indlela yokuxhuma i-Welding

I-valve yebhola eneziqephu ezintathu eshiselwe umoya ithatha indlela yokuxhuma i-welding, exhunywe ngokuqinile epayipini futhi ivimbele ngempumelelo ukuvuza. Ngaphezu kwalokho, uxhumano lwe-welding lunezinzuzo ezilandelayo:

(1) Ukumelana nokucindezela okuphezulu: Ukuxhumeka kwe-welding kungamelana nokucindezela okuphezulu futhi kulungele izinga lokushisa eliphezulu nezimo zokucindezela okukhulu.

(2) Ukumelana nokugqwala okuhle: Ukuxhumana kokushisela kunokumelana nokugqwala okuhle futhi kungasetshenziswa ezindaweni zemidiya ezigqwala kakhulu.

(3) Ukufakwa kalula: Uxhumano lwe-welding lwenza lula inqubo yokufaka futhi lunciphise izindleko zobunjiniyela.

3. Ukukhethwa kwempahla yevalve yebhola eneziqephu ezintathu zepneumatic

3-1. Impahla yomzimba ye-valve

Emazingeni okushisa aphezulu kanye nendawo enengcindezi ephezulu, ukukhethwa kwempahla yomzimba ye-valve kubalulekile. Amavalvu ebhola aneziqephu ezintathu ze-pneumatic ashiselwe ngokuvamile asebenzisa izinga lokushisa eliphezulu nezinto ezicindezelayo njengensimbi engagqwali nensimbi eyingxubevange, anokumelana nokugqwala okuhle namandla okushisa aphezulu.

3-2. Izinto zebhola

Ibhola liyingxenye eyinhloko ye-valve yebhola, futhi ukukhethwa kwezinto zayo kuthinta ngokuqondile ukusebenza kokuvala nokuqina kwe-valve. Ama-valve ebhola aneziqephu ezintathu ze-pneumatic welded asebenzisa izinto ezingagugi ezifana ne-carbide ne-ceramics ukuze kuqinisekiswe ukwethembeka nokuphila kwesevisi ye-valve ngaphansi kwezinga lokushisa eliphezulu kanye nezindawo ezicindezelayo.

4. Izinzuzo zokusebenza ze-pneumatic welded ama-valve amabhola amathathu

4-1. Ukusebenza kahle kokufakwa uphawu

I-valve yebhola eneziqephu ezintathu eshiselwe emoyeni ithatha isakhiwo sebhola elintantayo ukuze ifinyelele ukulingana phakathi kwesihlalo sevalvu nebhola, yehlise ngempumelelo izinga lokuvuza. Ngaphansi kwezinga lokushisa eliphezulu nezimo zokucindezela okukhulu, ukusebenza kwayo kokubeka uphawu kuhle kakhulu.

4-2. Izinga lokushisa eliphezulu kanye nomfutho ophezulu wokuthwala umthamo

I-valve ye-pneumatic welded ye-ball valve yenziwe ngezinga lokushisa eliphezulu kanye nezinto ezicindezelayo, ezingamelana namazinga okushisa aphezulu kanye nezingcindezi futhi ifanele izimo zokusebenza ezinzima.

4-3. Kulula ukusebenza

I-valve yebhola eneziqephu ezintathu eshiselwe umoya isebenzisa i-actuator yomoya ukuze ifinyelele isilawuli kude sevalvu futhi inciphise umfutho wokusebenza komsebenzisi. Ngesikhathi esifanayo, i-actuator ye-pneumatic inezinzuzo zejubane lokuphendula ngokushesha kanye nokunemba kokulawula okuphezulu.

5. Isiphetho

Ngokuhlola okujulile kwesakhiwo, izinto zokwakha kanye nokusebenza kwe-valve yebhola eneziqephu ezintathu ze-pneumatic welded, leli phepha lifinyelela iziphetho ezilandelayo:

5-1. I-valve ye-pneumatic welded ye-ball-piece-piece ball ithatha umklamo wesakhiwo sezingxenye ezintathu kanye nendlela yokuxhuma i-welding, enezici zesakhiwo esiqinile nokumelana nokushisa okuphezulu nokucindezela okukhulu.

5-2. Umzimba we-valve kanye nebhola zenziwe ngokushisa okuphezulu kanye nezinto zokucindezela okuphezulu kanye nezinto ezingagqoki ukuze kuqinisekiswe ukwethembeka nokuphila kwesevisi ye-valve ngaphansi kwezimo zokusebenza ezinzima.

5-3. I-valve yebhola ye-pneumatic welded ye-3-piece inokusebenza okuhle kokuvala, izinga lokushisa eliphezulu kanye nomfutho ophakeme wokuthwala umthamo kanye nokusebenza okulula, futhi inohlu olubanzi lwamathemba okufaka isicelo ngaphansi kwezimo zokusebenza ezinzima.

Ngamafuphi, ukwethembeka kwe-valve ye-pneumatic welded ye-ball valve ngaphansi kwezimo ezinzima zokusebenza kuqinisekiswe ngokugcwele, okunikeza isiqinisekiso esiqinile sokukhiqizwa kwezimboni. Ezenzweni ezisebenzayo, i-valve ye-pneumatic welded ye-ball-piece-piece kufanele ikhethwe ngokufanelekile futhi ihlelwe ngokuvumelana nezimo zokusebenza kanye nezici eziphakathi nendawo ukuze kuqinisekiswe ukusebenza kwayo okuzinzile ngaphansi kokushisa okuphezulu kanye nendawo yokucindezela okukhulu.
