I. Izimiso Eziyinhloko kwe-Valve Sourcing
Ama-valve ezimboni kanye nezesekeli zawo kuyizinto ezibalulekile emsebenzini ezinhlelweni zokulawula uketshezi. Impumelelo yokuthengwa komhlaba wonke ayixhomekile ekuqinisekiseni intengo yokuqala ephansi kakhulu, kodwa ekuqondeni izinsika ezine eziyisisekelo zobunjiniyela kanye nokuhambisana nemithetho.
1. Ukufanisa Okujwayelekile
Ukuqinisekisa ukuthi amazinga obukhulu kanye nokuklama ahambisana kahle. Ukungafani kobukhulu bobuso nobuso (isb., i-ASME B16.10 vs. EN 558) noma ukubhoboza i-flange kungaholela ekwehlulekeni okukhulu kokufakwa kanye nokubambezeleka kwephrojekthi. Yonke imininingwane kumele iqinisekiswe.
2. Ukuzivumelanisa Nezinto Nesimo
Ukukhethwa kwezinto kumele kubhekele ukugqwala koketshezi, izilinganiso zokushisa kwengcindezi, ukugoba, kanye nokukhanya. Ukusebenzisa izinsimbi ezingagqwali ezimbili noma ama-alloy angaphandle kuyimpoqo ezimweni ezinzima zesevisi njengokugxila okuphezulu kwe-H2S.
3. Amafayela Okulandelela Nokukala
Imibhalo ephelele ayinakuxoxiswana ngayo. Lokhu kufaka phakathi i-EN 10204 3.1/3.2 Mill Test Reports (MTRs), i-Positive Material Identification (PMI), kanye nezinombolo zokushisa ezigxivizwe emizimbeni ebonakalayo ukuqinisekisa ukulandeleka kwensimbi okungu-100%.
4. Imithethonqubo Yemakethe Eqondiwe
Ukuthobela imithetho yesifunda kusho ukungena emakethe. Kungakhathaliseki ukuthi kuyisiqondiso se-CE/PED se-European Union, izimemezelo zemvume yokukhishwa kwegesi e-EPA e-USA, noma isitifiketi se-EAC se-Eurasian Customs Union.
II. Ukuhlukaniswa Komkhiqizo kanye nokugxila kobuchwepheshe
Ukuqonda okuningiliziwe kwezingxenye ze-valve kubalulekile ekutholakaleni okuphumelelayo komhlaba wonke. Sihlukanisa imikhiqizo ngezigaba ezintathu zobuchwepheshe ezihlukile, ngayinye idinga izinqubo ezithile zokukhiqiza nokuhlola.

III. Izinga Lomhlaba Wonke I-Matrix Yezinhlelo
Ukuhamba ngenethiwekhi eyinkimbinkimbi yezindinganiso zomhlaba wonke ngumsebenzi obaluleke kakhulu kumthengi wezimboni. Ngezansi ukuhlukaniswa okusebenzayo kwezinhlaka zokuthobela imithetho ezibaluleke kakhulu.
1. Izindinganiso Zokuklama Nomkhiqizo
Lezi zindinganiso zilawula ubukhulu obubonakalayo, ubukhulu bodonga, kanye nendlela yokusebenza kwama-valve:
- I-API 6D: Imininingwane yama-Pipeline nama-Piping Valve. Kubalulekile emikhakheni ephakathi kukawoyela negesi.
- I-API 600: Amavalvu Esango Lensimbi - Iziphetho Ezinezinqe Nezimbobo Zokushisela, Amabhonethi Anezimbobo.
- I-API 608: Amavalvu Ebhola Lensimbi - Iziphetho Ezinezimbobo, Ezinentambo, Nezokushisela.
- I-API 609: Amavalvu Ovemvane: Uhlobo Oluphindwe Kabili Olunezimbobo Ezimbili, Uhlobo Lwezimbobo Ezinkulu kanye Nohlobo Lwesitsha Esincane.
- I-ASME B16.34: Amavalvu - Isiphetho Esinezimbobo, Esinentambo, kanye Nokushisela (Izilinganiso Zokucindezela Nokushisa).
- I-DIN / EN / ISO: Izindinganiso ezihlangene zaseYurophu eziqinisekisa ukuhambisana kwemingcele ngaphakathi kwe-EU.
2. Izindinganiso Zokuhlola Nokuhlola
Ukuqinisekiswa kwenqubo yokukhiqiza ngokuhlolwa okuqinile:
- I-API 598: Ukuhlolwa Nokuhlolwa Kwevalvu. Kuhlanganisa amazinga okuvuza amukelekayo kokubili ukuhlolwa koketshezi kanye negesi.
- I-ISO 5208: Amavalvu ezimboni - Ukuhlolwa kwengcindezi yamavalvu ensimbi.
3. Izinto Ezibalulekile Nokulwa Nokugqwala
Kubalulekile ekucutshungulweni kwamafutha negesi kanye namakhemikhali akhuphukayo:
- I-NACE MR0175 / ISO 15156: Izinto ezisetshenziswa ezindaweni eziqukethe i-H2S ekukhiqizweni kukawoyela negesi. Ibeka imingcele eqinile yokuqina (isb., i-HRC engu-22 max) ukuvimbela ukuqhekeka kwe-Sulfide Stress (SSC).
4. Izindinganiso Zokukhishwa Okuphansi Kokubaleka
Njengoba imithethonqubo yezemvelo ikhula emhlabeni jikelele (njengoMthetho Womoya Ohlanzekile wase-US EPA), ukulawula ama-Volatile Organic Compounds (ama-VOC) aphuma eziqwini zama-valve kubaluleke kakhulu.
- I-ISO 15848-1 kanye ne-2: Ama-valve ezimboni - Izinqubo zokulinganisa, ukuhlola kanye nokufaneleka kokukhishwa kwegesi okubalekayo.

IV. Ukulawulwa Kwekhwalithi Okuthuthukisiwe kanye nokuhlolwa kwefektri
Umhlahlandlela wokuthola ulwazi osebenzayo kumele ukhulume ngendlela yokuhlola ikhono langempela lomkhiqizi. Ukuqinisekiswa kwephepha akwanele; ingqalasizinda yokulawula ikhwalithi ebonakalayo iyadingeka.
Amakhono Okusebenza Ngemishini Yangaphakathi
Umkhiqizi wamavalvu ohamba phambili kumele abe nezikhungo zomshini we-CNC ezithuthukisiwe. Ukunemba kwesikhwama sesihlalo sevalvu kanye ne-stem bore kuthinta ngqo ikhono levalvu lokuphumelela ukuhlolwa kwesihlalo se-API 598 kanye nokuhlolwa kokukhishwa kwe-API 624 okusabalele. Bheka amakhono omshini we-5-axis kanye nokuhlolwa kwe-CMM (Coordinate Measuring Machine) okuzenzakalelayo.
Ilebhu Yensimbi
Ukuthembela kuphela ezitsheni zangaphandle kuyingozi. Abahlinzeki abaphezulu bagcina ama-spectrometer angaphakathi endlini ukuze ahlaziywe ngamakhemikhali, imishini yokuhlola ukujiya/ukuqinisekiswa kwamandla okucindezela, kanye nabahloli bomthelela be-Charpy V-notch ukuqinisekisa ukuthi izinto zisebenza ngokuphephile ezindaweni ezi-cryogenic noma ezicindezela kakhulu.
Ukuhlolwa Kokwamukelwa Kwemboni (i-FAT)
I-FAT iyisithiyo sokugcina ngaphambi kokuthunyelwa. Ihilela ukufakaza (ngokuvamile ngabahloli bezinkampani zangaphandle njenge-SGS, TUV, noma i-DNV) ukuhlolwa kwe-hydrostatic kanye ne-pneumatic kwama-valve. Amashadi okuqopha ingcindezi yedijithali kufanele anikezwe ukuze afakazele ukuthi ingcindezi ibanjwe isikhathi esibekiwe esijwayelekile ngaphandle kokwehla kwengcindezi.
Ukulandelela Izinto
Ukubekezelela Ukuvuza
Ukuhlolwa Kwekhwalithi
V. Mayelana Nokukhiqiza Kwethu Ubuhle
I-Sichuan Yining Machinery Equipment Co., Ltd. yasungulwa ngo-2005 futhi iyinkampani ekhethekile ekukhiqizeni nasekukhiqizeni izinhlobo ezahlukene zamavalvu nezesekeli zamavalvu eziqediwe. Eminyakeni edlule, besizinikele emkhakheni wamavalvu futhi sizibophezele ekuhlinzekeni ngemikhiqizo nezixazululo ezisezingeni eliphezulu nezisebenza kahle kumakhasimende emhlabeni jikelele.
Le nkampani ibilokhu ilandela ifilosofi yebhizinisi yokuthi "Ikhwalithi iyona eyinhloko, ikhwalithi ingumholo wethu", sigcizelela ekuthatheni ikhwalithi njengento ebalulekile futhi sibheke ikhwalithi yomkhiqizo ezinzile nethembekile njengesisekelo esiqinile sokubambisana isikhathi eside namakhasimende. Siyazi kahle ukuthi imikhiqizo esezingeni eliphezulu kanye namakhono okulethwa okuzinzile kuyizihluthulelo zentuthuko eqhubekayo yebhizinisi.
Inkampani idlulile isitifiketi sesistimu yokuphathwa kwekhwalithi ye-ISO9001 kanye nesitifiketi se-CE, futhi ilandela ngokuqinile amazinga omhlaba wonke okukhiqiza nokulawula ikhwalithi ukuqinisekisa ukuthi yonke imikhiqizo ihlangabezana nezidingo zemboni kanye namakhasimende.
Njengoba sineminyaka eminingi yesipiliyoni sokukhiqiza kanye namasu okukhiqiza avuthiwe, sinethimba lobuchwepheshe kanye nabaphathi abangochwepheshe abanolwazi olucebile lwethiyori kanye nokuhlangenwe nakho okusebenzayo. Sinamathela esiqondisweni sokuthuthukiswa "kokusungula izinto ezintsha, ukusungula ubuchwepheshe, kanye nokusungula izinto ezintsha zokuphatha", sithuthukisa njalo ikhwalithi yomkhiqizo kanye nokuncintisana kwebhizinisi.
Esikhathini esizayo, iSichuan Yining Machinery Equipment Co., Ltd. izoqhubeka nokuthatha ikhwalithi evelele njengengqikithi, izidingo zamakhasimende njengesiqondiso, futhi ibambisane nabalingani ukudala ubudlelwano bokubambisana besikhathi eside, obuzinzile nobuzuzisayo phakathi kwabo bonke.
VI. Uhlu Lokuhlola Lomthengi Olusebenzayo Ukuthengwa Kwevalvu
Sebenzisa lolu hlu lokuhlola olusebenzayo ukuze unciphise ubungozi, uqinisekise ukuthobela imithetho, futhi wenze lula imisebenzi yakho yomhlaba wonke yokuthola ama-valve nezesekeli.
