Yini iziAmavalvu e-OS&Y
Amavalvu e-OS&Y (Ngaphandle Kwesikulufo kanye Ne-Yoke) awuhlobo lwevalvu yezimboni eyenzelwe ukulawula ukugeleza okunembile ezinhlelweni zokucindezela okuphezulu. Umklamo wawo oyingqayizivele unesicu esinomucu esihamba phezulu naphansi ngaphandle komzimba wevalvu, ngendlela yejoka egcina isicu sizinzile. Isici esibonakalayo kakhulu samavalvu e-OS&Y yindawo ebonakalayo yesiqu: lapho isicu siphakanyisiwe, ivalvu ivulekile; uma yehliswa, ivaliwe. Lesi sibonakaliso esibonakalayo siwenza afaneleke kakhulu ekusetshenzisweni lapho ukuqinisekiswa kwesimo sevalvu esicacile kubalulekile, njengezinhlelo zokuvikela umlilo, amanethiwekhi okuhambisa amanzi, kanye namapayipi ezimboni.
Izinhlobo zama-OS&Y Valve
Ama-valve e-OS&Y atholakala ngezindlela ezimbili eziyinhloko, ngayinye ifanele izinhlelo zokusebenza ezithile:
1. I-valve yesango le-OS&Y
–Umklamo: Ifaka isango elinomumo ofana nowesikwele elihamba ngokuqondile ekugelezeni kokuqala noma kokumisa imidiya.
–Umsebenzi: Kuhle kakhulu ekusetshenzisweni kokuvula/ukuvala lapho ingcindezi yehla kancane.
–Ukusetshenziswa Okuvamile: Ukusatshalaliswa kwamanzi, izinhlelo zokufafaza umlilo, kanye namapayipi kawoyela/igesi.
2. I-valve ye-OS&Y Globe
–Umklamo: Isebenzisa indlela yediski nesihlalo ukulawula ukugeleza kokunyakaza okuqondile.
–Umsebenzi: Isebenza kahle kakhulu ekunqandeni noma ekulungiseni amazinga okugeleza.
–Ukusetshenziswa Okuvamile: Izinhlelo zomusi, i-HVAC, kanye nezindawo zokucubungula amakhemikhali.
Uma uthenga la ma-valve, hlala usebenzisana nomuntu othembekileUmkhiqizi weValvu YesangonomaUmkhiqizi we-Globe Valveukuqinisekisa ikhwalithi kanye nokuhambisana nezindinganiso zemboni.
Izinzuzo zama-OS&Y Valve
Ama-valve e-OS&Y ayathandwa ngenxa yokuthembeka kwawo nokuqina kwawo. Nasi isizathu:
1. Isibonakaliso Sendawo Ebonakalayo
Isiqu esiveziwe sinikeza isiqinisekiso esisheshayo sesimo se-valve, kunciphisa amaphutha okusebenza.
2. Ukwakhiwa Okuhlala Isikhathi Eside
Yakhelwe ukumelana nokucindezeleka okuphezulu kanye namazinga okushisa, okwenza ifaneleke ezindaweni ezinzima.
3. Ukulungiswa Okulula
Umklamo wejoka uvumela ukuhlukaniswa okulula ngaphandle kokususa ivalvu epayipini.
4. Ukuvimbela Ukuvuza
Izindlela zokuvala eziqinile (isb., amasango okugoqa ngaphakathiAmavalvu esango le-OS&Ynoma amadiski kuAmavalvu e-globe e-OS&Y) nciphisa izingozi zokuvuza.
5. Ukuguquguquka
Iyahambisana namanzi, umusi, uwoyela, igesi, kanye noketshezi oluqothulayo, kuye ngokuthi izinto ezikhethiwe zinjani njengethusi, insimbi ephonswe, noma insimbi engagqwali.
Isikhathi Sokukhetha Ama-valve e-OS&Y
Ama-valve e-OS&Y awazona izixazululo ezijwayelekile kodwa asebenza kahle ezimweni ezithile:
1. Izinhlelo Zokuphepha Ezibucayi
Izinhlelo zokuvikela umlilo (isb., ama-sprinkler) zidinga ukuqinisekiswa okucacile kokuvula/ukuvala, okwenzaAmavalvu esango le-OS&Yisisekelo sokulawula.
2. Izicelo Zokucindezela Okuphezulu
Umklamo wabo oqinile ubhekana nokucindezeleka okukhulu ezindaweni zokuhluza uwoyela, iziteshi zikagesi, kanye nezindawo zamanzi.
3. Ukusebenza Okuvamile
Indlela yokusebenza kwesiqu esinezintambo iqinisekisa ukusebenza kahle ngisho nangemva kokusetshenziswa okuphindaphindiwe.
4. Izimboni Ezilawulwayo
Izimboni ezifana nemithi noma ukucubungula ukudla zivame ukuphoqelela ama-valve e-OS&Y ukuthi alandele imithetho yenhlanzeko nokuphepha.
5. Izidingo Zokuphoqa
Khetha i-I-valve ye-globe ye-OS&Yuma kudingeka ukulawula ukugeleza okunembile, njengasemigqeni yomusi noma izinhlelo zokupholisa.
Ukukhetha Umkhiqizi Ofanele
Ukuze uthuthukise ukusebenza, sebenzisana nabaqinisekisiweAbakhiqizi beValve YesangonomaAbakhiqizi be-Globe ValveI-WHO:
- Landela amazinga e-ASTM, ANSI, noma e-API.
- Okunikezwayo ngokwezifiso (izinto zokwakha, osayizi, izilinganiso zokucindezela).
- Nikeza izitifiketi zokuhlola kanye nokusekelwa kwangemva kokuthengisa.
Isiphetho
Amavalvu e-OS&Yzibalulekile ezimbonini ezifuna ukuthembeka, ukuphepha, kanye nokunemba. Kungakhathaliseki ukuthi udinga i-I-valve yesango le-OS&Yyokulawula okuvula/okuvala nomaI-valve ye-globe ye-OS&YUkuze kulawulwe ukugeleza, ukuqonda amandla azo kuqinisekisa ukusebenza kahle kwesistimu. Njalo beka phambili ikhwalithi ngokubambisana nabakhiqizi abathembekile ukuze kuhlangatshezwane nezidingo zakho zokusebenza.
