I-High-Pressure Globe Valve

Singumkhiqizi wamavalvu onolwazi onezitifiketi ezigcwele ze-ISO, CE kanye ne-API. Indawo yethu yokusebenzela ifakwe imishini ephelele yokwenza imishini kanye nezinqubo eziqinile zokuhlola ikhwalithi yezinyathelo eziningi. Samukela izicelo zangokwezifiso ze-OEM ne-ODM, futhi singakwazi ukwamukela ama-oda amancane esilingo kalula. Amavalvu embulunga ethu aqinile anengcindezi ephezulu athunyelwa ezimakethe eziningi zaphesheya futhi azuza ukwethenjwa okungaguquki kubalingani bomhlaba wonke.

Izimfanelo Ezibalulekile

Iziphi izinto zomzimba nezinto zokulungisa ongazinikeza ngegesi ebolayo, emuncu noma izinga lokushisa eliphezulu?

Senza ngokwezifiso izinto ezisetshenziswayo ngokugcwele ngokusekelwe kumaphakathi, izinga lokushisa kanye nemingcele yengcindezi:

Isitimu esivamile, amanzi kanye namafutha kaphethiloli: I-A216 WCB carbon steel, i-A105 yomzimba wensimbi eyakhiwe, isiqu se-nitrided 2Cr13;

Izinga lokushisa eliphezulu ngaphezu kuka-420℃: WC6, WC9 chrome-moly alloy steel;

I-acid edliwayo, i-alkali noma i-brine: i-CF8, i-CF8M insimbi engagqwali, insimbi eyi-duplex, i-Hastelloy C276 trim;

Ipayipi legesi elimuncu / likawoyela negesi: Ingxubevange ye-NACE MR0175 enobunzima obulawulwayo ukuze kugwenywe ukuqhekeka kwengcindezi ye-sulfide.

Zonke izindawo zokuvala ziyi-Stellite hard alloy overlay, efinyelela ukuvuza kwe-Class VI eziro ukuze kusetshenziswe umthwalo osindayo wesikhathi eside.

Yiziphi iziphetho zokuxhuma kanye nezinketho ze-actuator ezitholakala kuma-valve embulunga yomfutho ophezulu?

Sinikezela ngezinhlobo eziningi zokuxhuma ukuze zifane namazinga ahlukene wamapayipi aphesheya kwezilwandle: i-flanged, i-butt-weld BW, i-socket-weld SW kanye nemiphetho enentambo. Singalungisa ukubhoboza imbobo ye-flange kube i-ASME B16.5 noma i-HG20592 GB ejwayelekile njengesicelo samakhasimende.

Ngamamodi okusebenza, sinikeza isondo lesandla elenziwa ngesandla, isondo legiya, i-actuator kagesi kanye ne-pneumatic actuator. Amavalvu eglobhu asebenza ngokuzenzakalelayo asebenza ngokuzenzakalelayo asekela ukugeleza okukude nokuvalwa okuphuthumayo, amukelwa kabanzi ezinhlelweni zokulawula amakhemikhali namandla azenzakalelayo.

Ingabe uyakweseka ukwenza ngokwezifiso kwe-OEM ne-ODM? Ingabe i-oda elincane lesivivinyo liyamukeleka kumavalvu eglobhu anomfutho ophezulu?

Sisekela i-OEM eguquguqukayo yokwenza ngokwezifiso kanye ne-ODM, futhi asibeki izimfuneko eziqinile zama-oda amakhulu kumakhasimende amasha. Amavalvu eglobhu asezingeni eliphezulu e-WCB ayatholakala kuma-oda amancane esilingo, ngisho namayunithi angu-1 kuye kwayi-5. Ngezinto ezikhethekile ze-alloy noma amamodeli enziwe ngokwezifiso e-ultra-high, singenza ucezu olulodwa lokuhlola kwakho isampula.

Inothi eliwusizo nje: Uma ufuna ukuphrinta uphawu lwakho lokuthengisa olubhalisiwe kumavalvu, sicela unikeze ifayela lakho lokugunyaza uphawu lokuhweba kusenesikhathi. Lokhu kungagwema ngempumelelo noma yikuphi ukuhlolwa okuhlobene ne-IP noma izinkinga zokugunyazwa endaweni oya kuyo.

Singakanani isikhathi sakho sokuhola sokukhiqiza samavalvu eglobhu ajwayelekile nangokwezifiso aphezulu?

I-DN15-DN100 ye-WCB ye-WCB yebhulokhi yebhuloho yokucindezela okuphezulu inezitokwe eziphelile, ukulethwa kuthatha izinsuku ezingu-3-7 kuphela ngemuva kwediphozithi.

Ama-oda avamile we-DN150-DN600 anosayizi omaphakathi nomkhulu adinga umjikelezo wokukhiqiza wezinsuku ezingama-25-40.

Ingxubevange ye-WC6/WC9 yangokwezifiso, i-Class 1500 i-ultra-high noma amavalvu asebenza ngokuzenzakalelayo adinga izinsuku zokusebenza ezingama-40-60. Singahlela imigqa yokukhiqiza ebalulekile yamaphrojekthi onjiniyela aphuthumayo ukuze sifinyeze isikhathi sokuhola ngendlela efanele.

Yiziphi izimboni amavalvu eglobhu anomfutho ophezulu afaneleka kakhulu kuzo?

Ama-valve ethu eglobhu anomfutho ophakeme athunyelwa emazweni angaphandle futhi asetshenziswa kule mikhakha yezimboni ewumgogodla:

1. Izitshalo eziphehla ugesi: Amanzi okuphakela ibhoyili, ukuphehla nokuvalwa kwepayipi lesitimu elinomfutho omkhulu;

2. Izindawo zokuhluza uwoyela negesi, iziteshi zokuhambisa igesi yemvelo;

3. Izitshalo zokucubungula i-Petrochemical ezinezinga eliphezulu lokushisa kanye ne-high-pressure medium;

4. Ukwelashwa kwamanzi anengcindezi ephezulu yezimboni kanye nezinhlelo zomoya ezicindezelwe;

5. Imigqa yokukhiqiza yamandla ashisayo, i-geothermal kanye namakhemikhali asindayo.

Ngokungafani namavalvu ebhola kuphela ngokuvuleka/kuvaleka okugcwele, amavalvu eglobhu anomfutho ophezulu aletha ukulawulwa okunembile kokugeleza, okuwenza abe yinketho ephezulu yesevisi yokudonsa kwamapayipi.

Ungawagcina kanjani ama-valve eglobe anomfutho ophezulu ukuze andise impilo yesevisi?

Ukunakekelwa okuyisisekelo kusiza ukunciphisa kakhulu ukuphuka kwama-valve, ikakhulukazi kumayunithi asebenza ngaphansi kwengcindezi ephezulu:

1. Hlola i-Stellite sealing trim njalo ezinyangeni ezintathu kuya kweziyisithupha ukuze ubone noma yikuphi ukuguga noma ukulimala kusenesikhathi;

2. Gcoba isiqu se-valve nezingxenye zegiya njalo ukuze i-valve ingabambeki noma ijike ngokuvilapha.

3. Ungagcini i-valve isebenza endaweni encane kakhulu isikhathi eside, njengoba lokhu kuzodala ukuguguleka okukhulu kanye ne-cavitation ezingxenyeni zangaphakathi;

4. Hlanza ukungcola kwamapayipi kanye nemfucumfucu ngaphambi kokufaka, ukuze izinhlayiya eziqinile zingaklwebheli indawo yokuvala ivalvu.
