I-High-Pressure Gate Valve

Singumkhiqizi wamavalvu oqinisekisiwe onemininingwane ye-ISO ne-API, efakwe imigqa yokukhiqiza enembayo kanye ne-QC yobubanzi obugcwele obuqinile okuhlanganisa nokuhlolwa kwe-API 598 hydrostatic. Ukwenza ngokwezifiso kwe-OEM ne-ODM kuyatholakala nge-MOQ eguquguqukayo yama-oda wesivivinyo nama-oda amaningi. Ama-valve ethu amasango anengcindezi ephezulu athunyelwa emhlabeni jikelele futhi anconywa kakhulu ngamakhasimende onjiniyela.

Yiziphi izinhlobo zezimo zokusebenza lawa ma-valve amasango anomfutho ophezulu ongajwayela kuzo?

Asebenza njengemishini yokunqamula yodwa egcwele ngokugcwele yamapayipi anomfutho ophezulu, asetshenziswa kakhulu ekuthuthweni kukawoyela negesi, ezimbonini zamandla ashisayo, izindawo zokuhluza amakhemikhali kanye nezintambo zesitimu esishisa kakhulu. Avula noma avale ngokugcwele ukugeleza ukuze kugcinwe amapayipi kanye nokuvalwa okuphuthumayo.

Izimfanelo Ezibalulekile

Ingabe lolu hlobo lwe-valve yesango lufanelekile umsebenzi wokulungisa i-throttling noma ukucindezela?

Lutho neze. Lawa ma-valve esango aklanyelwe kuphela ukuzihlukanisa ngaphandle kokusebenza. Ukuvula kancane i-valve kuzoholela ekugugulekeni okukhulu kwendawo evalekayo ye-hard-alloy wedge ngendlela egeleza ngokushesha, okuholela ekuvuzeni okungapheli. Ama-valve okulawula akhethekile ayadingeka ukuze kuncishiswe ingcindezi nokulawula ukugeleza.

Yiziphi izinto zokusetshenziswa ezingena ekukhiqizeni lawa mavalvu esango anomfutho ophezulu?

Umzimba & nebhonethi: I-Cast A216 WCB, i-A105 eyenziwe ngokwenziwa, i-low-temperature A350 LF2 carbon steel

Isiqu se-valve: A182 F304, A182 F316 noma 13Cr insimbi engagqwali

I-Wedge disc: I-substrate yensimbi ye-Carbon ene-Stellite yangaphandle eqinile

Ubuso besihlalo: I-Stellite / Inconel hard alloy

Ama-gaskets okuvala: ama-RTJ metal ring gaskets, ama-graphite spiral amanxeba gaskets

Ensizakalweni yamapayipi anomfutho ophezulu, yiziphi izinzuzo ezenza amavalvu esango anomfutho ophezulu abe yisinqumo esingcono uma kuqhathaniswa namavalvu ebhola namavalve uvemvane?

Okokuqala, i-bore yabo egcwele eqondile iletha cishe ukumelana nokugeleza kweqanda; ama-valve ebhola anezimbotshana ezivaleleke futhi ama-butterfly valve anezithiyo zediski zangaphakathi ezidala ukulahlekelwa kwengcindezi eyengeziwe.

Okwesibili, uhlaka lwe-All-metal hard seal wedge lungathwala ingcindezi ye-ultra-high Class 2500 kanye nezinga lokushisa eliphezulu, kuyilapho ama-valve e-soft-seal and butterfly azohluleka ngaphansi kwemithwalo eshisa kakhulu nengcindezi.

Okwesithathu, imizimba ewugqinsi enodonga olusindayo kanye namabhonethi ashiselwe ngokuzithandela asusa izingozi zokuvuza, ibhola elintantayo namavalve uvemvane oluyisicwecwana angakwazi ukuxazulula amaphayiphi aphakathi nendawo anomfutho ophezulu ovuthayo.

Okwesine, asekela isitifiketi sokuphepha emlilweni se-API 6D, izinga lokuphepha eliyisibopho amavalvu amaningi ovemvane angakwazi ukuhlangabezana nalo.

Yimiphi imiklamo yesakhiwo eyinhloko ehlukanisa i-valve yesango yokucindezela okuphezulu?

Imbobo eqondile yepayipi eligcwele ukunqamula ukulahleka kokugeleza

I-Wedge eqinile noma ehlukanisiwe ehlanganiswe ne-Stellite alloy ukuze ivalwe ngebhamuza lensimbi ukuya kwensimbi

Umzimba owugqinsi wodonga oluwugqinsi/i-carbon steel eyakhiwe, ibhonethi eshiselwe ebhowudiwe noma engacindezeli

I-RTJ metal ring flange gaskets yokutywinwa okuthembekile kokucindezela okukhulu

I-multi-layer backseat stem seal ukumisa ukuvuza okumaphakathi kwangaphandle

Ithobelana ngokugcwele ne-API 6D, ASME B16.34, edlula i-API 598 hydrostatic nokuhlolwa kokuphepha emlilweni

Izinketho zokushayela eziningi: isondo lesandla, ibhokisi legiya, ugesi, i-pneumatic noma i-hydraulic actuator
