I-Fixed Ball Valve

Singumenzi wamavalvu ochwepheshe ophethe izitifiketi ze-ISO, API kanye ne-CE. Siphethe imishini yokukhiqiza ethuthukisiwe kanye nesethi egcwele yezinhlelo zokulawula ikhwalithi. Futhi samukela ama-oda we-OEM ne-ODM, anamanani amancane avumelana nezimo. Imikhiqizo yethu ethembekile ithunyelwa emhlabeni wonke futhi izuza ukuqashelwa okubanzi kumakhasimende.

Iyini i-trunnion efakwe i-valve yebhola engashintshi?

Ama-valve ebhola angashintshi afakwe e-Trunnion akhelwe ukucindezela okukhulu namapayipi amakhulu obubanzi. Uma kuqhathaniswa namavalvu ebhola antantayo, ibhola livalwa endaweni ngesiqu se-valve engaphezulu kanye ne-trunnion shaft engezansi. Imane ijikeleze ukuze ivuleke futhi ivalwe ngaphandle kokukhukhuleka lapho ingcindezi isebenza. Isakhiwo se-trunnion sithatha umthwalo omkhulu wengcindezi yoketshezi, kwehlisa ngempumelelo ukungqubuzana esihlalweni sokuvala. Lo mklamo wenza ama-valve ebhola angaguquki azinze futhi ahlale isikhathi eside ekusebenzeni kwezimboni isikhathi eside.

Uyini umehluko phakathi kwe-valve yebhola engashintshi kanye ne-valve yebhola elintantayo?

Lona umbuzo ovame ukubuzwa ngabathengi bomhlaba. Umehluko oyinhloko usesakhiweni esisekela ibhola kanye nemodi yokuthwala ingcindezi.

Ama-valve ebhola antantayo awanawo usekelo lwe-trunnion ephansi. Lapho umfutho wepayipi ukhuphuka, i-medium iphusha ibhola ngokuqinile esihlalweni esingezansi komfula. Lokhu kudala ukungqubuzana okukhulu, itorque ephezulu yokusebenza kanye nokuguga kwezihlalo ezisheshayo. Izinhlobo ezintantayo zifaneleka kuphela usayizi omncane kanye nezimo zokusebenza ezinengcindezi ephansi kuya emaphakathi.

Ama-valve ebhola e-trunnion alungisa ibhola endaweni. Umthwalo wengcindezi wenziwa i-trunnion shaft ne-body bear, hhayi isihlalo sokuvala. Ifaka i-torque ephansi yokusebenza, ukuhuzuka kwesihlalo okuncane, ukusebenza kokuvala okuzinzile nempilo ende yesevisi. Ku-DN100 / NPS4 nangaphezulu kwamapayipi amakhulu noma anengcindezi ephezulu, ama-valve amabhola angashintshi ahlala eyinketho yokuqala kubunjiniyela bezimboni.

Izimfanelo Ezibalulekile

Asetshenziswa kuphi ama-valve ebhola angashintshiwe?

Ama-valve ebhola e-Trunnion asetshenziswa kabanzi ezimeni ezisindayo zezimboni ezidinga ukuvala uphawu okuzinzile nempilo ende yesevisi. Izimboni ezijwayelekile zihlanganisa amapayipi ahambisa uwoyela negesi, izitshalo ze-petrochemical, iziteshi zikagesi ezishisayo, amaphrojekthi okuhlanza amanzi, amagalaji kaphethiloli wemvelo kanye nezinhlelo zokulethwa koketshezi olude ezimbonini. Ifaneleka ngokukhethekile izimo zokusebenza ezinomfutho ophezulu, izinga lokugeleza elikhulu, ukushintsha njalo kanye nezidingo eziqinile zokuvuza kwe-zero.

Yiziphi izinto ezisetshenziswayo ozisekelayo zemizimba ye-valve yebhola engashintshi kanye nezingxenye zangaphakathi?

Sinikeza uhla lwezinto zokwakha zomzimba nezangaphakathi ukufanisa izimo zokusebenza ezihlukene. I-WCB carbon steel iyisinqumo sethu esijwayelekile samapayipi ezimboni ajwayelekile, aletha ukuqina okuthembekile ngentengo yokuncintisana. Ngezinkonzo ezinoketshezi olubolayo noma igesi, sikhetha i-CF8 (304) ne-CF8M (316) yensimbi engagqwali yokumelana nokugqwala okuthembekile.

Siyakwazi futhi ukuthola izinto ezikhethekile ezifana nensimbi enezinga lokushisa eliphansi kanye nensimbi ye-alloy kumaphrojekthi anzima, adinga kakhulu. Ezingxenyeni zangaphakathi ezifana nezihlalo zebhola ne-valve, siyakwazi ukumisa inhlanganisela ehlukene ngokusekelwe ezidingweni zakho zangempela zokusebenza. Izingxenye ze-Metal hard seal ziyatholakala ngezimo zokusebenza ezinzima, kuyilapho i-PTFE yakudala kanye ne-RPTFE izinto zokufaka uphawu ezithambile zinikezwa izimfuno zokuvumelana ngokugcwele nezimfuneko zephrojekthi.

Yiziphi izindinganiso nezitifiketi ama-valve akho ebhola angashintshi ahambisana nazo?

Wonke ama-valve ethu ebhola angaguquki afakwe ama-trunnion akhiqizwa ngokuqinile ngokuvumelana nezindinganiso zamazwe ngamazwe ze-API 6D kanye ne-ASME B16.34. Imboni yethu inezitifiketi eziphelele ze-API, ISO kanye ne-CE. Wonke ama-valve aqediwe adlula ukuhlolwa kokucindezela kwegobolondo lochwepheshe, ukuhlolwa kokuqina kwesihlalo kanye nokuhlolwa kokuqina komoya ngaphambi kokulethwa. Yonke imibiko yokuhlolwa kanye nemibhalo yesitifiketi inganikezwa ukuze kusekelwe ukuhlolwa kwephrojekthi yamakhasimende kanye nokugunyazwa kwamasiko.

Ingabe kufanele ngikhethe uphawu oluthambile noma i-valve yebhola egxilile yensimbi?

Kuncike endaweni yakho yepayipi kanye nezinga lokushisa lokusebenza. Amavalvu ebhola angashintshi ahlezi kahle asebenzisa ukuvala kwe-PTFE noma kwe-RPTFE, azuze ukuvuza kweqanda okuqinile kwebhamuza. Alungele amanzi ahlanzekile, igesi kanye ne-oyela yezinga lokushisa elivamile elinezidingo eziqinile zokuvala.

Ama-valve ebhola aqinile anensimbi eqinile angakwazi ukuzivumelanisa nezinga lokushisa eliphezulu, ukucindezela okuphezulu kanye nendawo equkethe izinhlayiya ezincane eziqinile. Isakhiwo sokuvala insimbi kuya kwensimbi siyamelana nokugqokwa futhi simelana nezinga lokushisa eliphezulu, sisetshenziswa kabanzi ezimweni ezinzima ze-petrochemical kanye nezimo zepayipi lokushisa eliphezulu.

Ingabe ama-valve ebhola angaguquki angafakwa ama-actuator kagesi noma we-pneumatic?

Yebo, kwenziwa ngendlela oyifisayo ngokugcwele. Ama-valve ethu ebhola angaguquki angafaniswa nokusebenza kwegiya lezandla, ama-pneumatic actuators, ama-actuator kagesi nama-hydraulic actuators. Ngenxa yesakhiwo sokusekela i-trunnion, i-torque yokusebenza iphansi kakhulu kunama-valve amabhola antantayo. Inganciphisa ngempumelelo izindleko zokucushwa zama-actuator futhi iqinisekise ukusebenza okuzinzile kokuvula nokuvala okuzenzakalelayo.

Iyini isiqinisekiso sakho sekhwalithi kanye nenqubomgomo yokuthengisa ngemva kokuthengisa?

Wonke ama-valve ethu ebhola angashintshi ama-trunnion ajabulela iwaranti yekhwalithi yesikhathi eside. Sinikeza ukwesekwa okuphelele kwezobuchwepheshe, isiqondiso sokufaka kanye nokubonisana ngemva kokuthengisa. Sigxila ebudlelwaneni bokubambisana besikhathi eside namakhasimende omhlaba, hhayi amadili esikhathi esisodwa.
