Umkhiqizi wevalvu yesango elivaliwe i-Bellows

Le valve yesango yakhiwe ngokuhambisana nezindinganiso ze-API futhi yenzelwe ukuhlangabezana nezidingo zokucindezela nokushisa kwe-ASME B16.34, ukuqinisekisa ukusebenza okuphephile ngaphansi kwezimo ezidinga amandla. Ukuxhumeka kwe-flanged end kuhambisana ne-ASME B16.5, okuvumela ukufakwa okulula nokuhambisana nezinhlelo zamapayipi ezijwayelekile. Ukuhlolwa nokuhlolwa kuvame ukuhambisana ne-API 598, okuqinisekisa ubuqotho bokucindezela kanye nokuqina kwesihlalo.

Isici esiyinhloko sale valve yi-metallic bellows seal yayo, enikeza isithiyo esingenawo umoya phakathi koketshezi lwenqubo kanye nomoya. Ama-bellows ngokuvamile akhiqizwa ngensimbi engagqwali, eklanyelwe ukumelana nokunyakaza kwesiqu okuphindaphindiwe kanye nokujikeleza kokushisa ngaphandle kokwehluleka ukukhathala.

Ngokungafani nama-valve avamile okupakisha kuphela, umklamo ovalwe nge-bellows uqeda ngokuphelele ukuvuza kwesiqu, ngisho nangaphansi kwezimo zokushisa okuphezulu, umfutho ophezulu, noma izimo zemidiya ezinobuthi. Ukuze kuphepheke kakhulu, ilungiselelo lokupakisha eliyisipele livame ukufakwa ngaphezu kwe-bellows, okunikeza ukuvalwa kwesibili uma kwenzeka ukwehluleka kwe-bellows. Lo mqondo wokuvala okubili uthuthukisa kakhulu ukuthembeka kokusebenza kanye nokuvikelwa kwemvelo.

I-valve isebenzisa umklamo wesango le-wedge, iqinisekisa ukuvalwa okuqinile nokusebenza okuzinzile kuzo zonke izinhlobo zokucindezela. Amasongo esango nezihlalo aklanywe ngokunemba ukuze kufezwe ukusebenza okuhle kakhulu kokuvala nge-torque encane yokusebenza. Kuye ngezidingo zokusetshenziswa, izindawo zokuhlala zingase zibe nzima ngama-alloy angagugi ukuze kuthuthukiswe ukumelana nokuguguleka, ukugqwala, kanye nokuqhekeka.

Le valve yesango yenzelwe ngokuyinhloko isevisi yokuvula/ukuvala, ihlinzeka ngokugeleza okugcwele kwebhore kanye nokwehla okuncane kwengcindezi uma ivuliwe ngokugcwele. Indlela yokugeleza eqondile inciphisa ukuxokozela futhi inciphise ukulahlekelwa amandla, okubaluleke kakhulu kumapayipi amakhulu.

Isiqu ngokuvamile senziwe ngensimbi engagqwali futhi sinesiqu esikhuphukayo, ukucushwa kwesikulufu ne-yoke yangaphandle (OS&Y). Lo mklamo uvumela ukubonakaliswa okulula kokubonakalayo kwendawo ye-valve futhi uvimbela imicu yesiqu ukuthi ingathintani ngqo noketshezi lwenqubo, okwandisa impilo yenkonzo.

Ukusebenza ngesandla kuyinto ejwayelekile, kusetshenziswa isondo lesandla elihlinzeka ngokuvulwa nokuvalwa okubushelelezi nokulawulwayo. Kwabakhulu noma amakilasi okucindezela okuphezulu, opharetha begiya noma ama-actuator anenjini anganikezwa ukuze kuncishiswe umzamo wokusebenza futhi kuvunyelwe ukulawula okukude.

Ama-valve esango avaliwe e-API akhiqizwa ku-ASME B16.34 atholakala ngezinhlobo eziningi zezigaba zokucindezela, ngokuvamile i-Class 150, 300, 600, nangaphezulu, kuye ngezidingo zomklamo. Osayizi bavame ukuba ngamasentimitha angu-2 kuya kwangu-24 noma ngaphezulu, okwenza afaneleke kokubili kumapayipi enqubo kanye nawokusetshenziswa.

Le valve ifaneleka kakhulu ezinsizeni lapho ukusebenza okungavuzi khona kubalulekile, okuhlanganisa:

Izinhlelo zomusi kanye nezokujiya

Uwoyela oshisayo kanye noketshezi lokudlulisa ukushisa

Imidiya enobuthi, eyingozi, noma ebizayo

Izinqubo ze-Petrochemical kanye ne-refinery

Izitshalo zikagesi kanye nezinsiza zezimboni

Ukwakhiwa okuvalwe nge-bellows kuyenza ibe usizo kakhulu ekusetshenzisweni lapho imithethonqubo yezemvelo kanye nezindinganiso zokuphepha endaweni yokusebenza zidinga ukusebenza okungekho kokukhipha ukungcola.

Izinzuzo ezibalulekile ze-API ASME B16.34 A216 WCB bellows sealed gate valve zifaka:

- Akukho ukuvuza kwesiqu nokusebenza okungenawo umoya

- Impilo yesevisi ende uma iqhathaniswa nama-valve ajwayelekile apakishiwe

- Ukunakekelwa okuncishisiwe kanye nezindleko eziphansi zomjikelezo wokuphila

- Ukusebenza okuthembekile ngaphansi kokushisa okuphezulu kanye nengcindezi

- Umklamo ogcwele we-bore onokulahlekelwa okuncane kwengcindezi
