2 Piece Flanged Ball Valve

Isebenza kahle ngisho nalapho isetshenziswa njalo, futhi isebenza kahle kakhulu kumapayipi ezimbonini zamakhemikhali, izindawo zokuhlanza amanzi, iziteshi zikagesi neminye imigqa yezimboni ejwayelekile.

Singumkhiqizi wamavalvu ochwepheshe onezitifiketi ze-ISO neze-API. Sisebenzisa imishini yokukhiqiza yesimanje futhi sihlola yonke imikhiqizo ngokucophelela ngesikhathi sokukhiqiza, ukuze zonke izinto ziphile ngokuvumelana nezindinganiso zamazwe ngamazwe. Singakwazi futhi ukwenza umsebenzi ngokwezifiso we-OEM kanye ne-ODM, futhi samukela ama-oda anamanani aphansi aphansi.Amavalvu ethu enziwe kahle athengiswa emhlabeni wonke futhi bathole ukwethenjwa okungaguquki kubathengi bomhlaba wonke.

Uyini umehluko phakathi kwama-valve ebhola anezingcezu ezi-2?

Umehluko omkhulu usekwakheni komzimba kanye nokugcinwa kahle:

I-1.I-Single piece (1PC) i-valve yebhola: Umzimba uyisiqephu esisodwa, uhlangene futhi unezindleko eziphansi. Ifakwe intambo kakhulu futhi akulula ukuyiqaqa noma ukuyilungisa esizeni. Ivamise ukusetshenziselwa izinhlelo zokusebenza ezinosayizi omncane, ezinengcindezi ephansi.

I-valve yebhola engu-2.2 (2PC): Umzimba wenziwe izingxenye ezimbili eziboshiwe. Lo mklamo uvumela ukuhlakazwa okuphelele ukuze kuhlolwe, kuhlanzwe futhi kugcinwe ngaphandle kokukhipha i-valve yonke epayipini. Ivamise ukusetshenziswa ezinhlelweni ze-flanged, ezinengcindezi ephezulu kanye nezisezingeni lezimboni njengezingcezu zethu ezi-2 ze-valve yebhola.

Izimfanelo Ezibalulekile

Isetshenziselwa ini i-valve yebhola ene-flanged?

Ama-valve ebhola ane-Flanged ayiyona ndlela yokukhetha yokulawula ukugeleza okuthembekile ezinhlelweni zamapayipi ezimbonini. Zakhelwe ukuphatha uketshezi, amagesi, isitimu, ngisho nama-slurry alula, okuzenza zisebenziseke kuzo zonke izinhlobo zezimboni. Uzowathola esetshenziswa kakhulu kumapayipi e-petrochemical nasemapayipini kawoyela nawegesi, ekuhlanzeni amanzi nasezindaweni zamanzi angcolile, izimboni zamandla kagesi nezinhlelo zokufudumeza, kanye nokudla neziphuzo kanye nemigqa yokukhiqiza imithi.

Okwenza ngempela ama-valve ebhola ane-flanged ahlukane yindlela yawo yokuxhumana. Uma kuqhathaniswa nama-valve anentambo, izinhlobo ezine-flanged ibhawudi iqonde epayipini eline-gasket phakathi. Lokhu kuxhumana kunamandla kakhulu, kuvala kahle kakhulu, futhi kwenza ukufaka nokuqondanisa kube lula kakhulu esizeni.

Yingakho zisetshenziselwa kakhulu amapayipi amakhulu kanye nezimo zokusebenza ezicindezelayo, lapho ukusebenza okuphephile nokuzinzile kuhlale kuqala. Enye inzuzo enkulu ukuthi zingasuswa kalula ukuze zihlolwe noma zilungiswe, okusiza ukonga isikhathi esiningi ngesikhathi sokuvalwa kwesistimu.

Ivalvu yebhola yezindlela ezi-2 ezijwayelekile isebenza ekujikeni okungu-90-degree. Ngaphakathi komzimba we-valve kuhlezi ibhola elingenalutho elifakwe ibhore eliqondile, elizungezwe izingxenye ezithembekile zokuvala. Uma uphendulela i-lever parallel nepayipi, imbobo ebholeni ifanelana nendawo yokugeleza, okuvumela imidiya ukuthi idlule kahle ngokulahleka kwengcindezi encane kakhulu.

Vula isibambo ngamadigri angu-90 kuphela, ngakho-ke i-perpendicular to the pipe, futhi ingxenye eqinile yebhola manje ivimba indlela yokugeleza ngokuphelele, ivala umugqa uqine. Yilokho kuphela okudingekayo ukusuka ekuvulekeni ngokuphelele kuye kokuvaleka ngokugcwele, akukho ukujika okuningi noma ukulungisa okudingekayo. Lo mklamo ukunika ukulawula/ukuvala okusheshayo, okuthembekile, nokwehla kwengcindezi encane kanye nengozi ephansi yokuvuza—ngisho nangemva kokusetshenziswa okuphindaphindiwe.

Uyini umehluko phakathi kwamavalvu ebhola eNgxenye 1 kanye neNgxenye 2?

Lokhu kufushane nje komkhakha wamavalvu ebhola esiqephu esingu-1 vs 2-piece, kubhekiselwa ekutheni umzimba wamavalvu wakhiwe kanjani, futhi kwenza umehluko omkhulu endleleni owasebenzisa ngayo futhi uwagcine kanjani:

Ingxenye 1 (i-valve yebhola yocezu olu-1): Wonke umzimba we-valve wenziwe njengesiqephu esisodwa esiqinile. Eziningi zalezi zinentambo, zihlangene, futhi zinezindleko eziphansi, okuzenza zidume ezinsizeni ezincane, ezinengcindezi ephansi njengamapayipi asekhaya noma imigqa yezimboni elula. Okubi ukuthi awukwazi ukuzihlukanisa—uma izigxivizo ziguga noma okuthile kubambeka, kufanele ushintshe i-valve yonke. Aziklanyelwe ukuhlakazwa noma ukulungiswa kwesayithi.

Nansi ivalve yebhola eneziqephu ezi-2. Njengoba igama lisikisela, umzimba wayo wakhiwe izingxenye ezimbili eziboshwe ndawonye ngamabhawudi, njengevalvu yethu yebhola ene-flanged.

Lo mklamo uletha lula kakhulu ukusetshenziswa kwezimboni. Ungamane uhlehlise amabhawodi ukuze uhlukanise i-valve. Khona-ke ungakwazi ukuhlanza ngaphakathi, uguqule izimpawu ezigugile noma usule ama-blockages kalula. Okuhle kunakho konke, awudingi ngisho nokukhipha i-valve yonke epayipini ukuze wenze le misebenzi.

Sekukonke, lawa ma-valve aqinile futhi kulula ukuwanakekela. Asebenza kahle kakhulu kumapayipi amakhulu, izindawo ezinomfutho ophezulu kanye nezindawo ezidinga ukusebenza njalo.
