I-Carbon Steel National Standard Gate Valve

Singumkhiqizi wamavalvu ochwepheshe onezitifiketi ze-ISO, API nezitifiketi ze-CE. Sinezindawo zokukhiqiza ezithuthukile futhi silawula ngokuqinile ikhwalithi kuyo yonke inqubo. Sithatha ama-oda e-OEM nawe-ODM, futhi i-MOQ yethu ivumelana nezimo kuzo zonke izinhlobo zamaphrojekthi. Amavalvu ethu adayisela izimakethe emhlabeni wonke, futhi amakhasimende ahlala efaka ama-oda aphindayo ngenxa yekhwalithi yethu enokwethenjelwa.

Yiziphi izici ezivame ukulandelwa ama-valve esango?

Ama-valve esango akhiwe ngamazinga ahlukene, kuye ngokuthi uzowasebenzisa kuphi futhi kanjani. Kumaphrojekthi asindayo ezimbonini nawowoyela negesi, i-API 600 iyindinganiso eyamukelwa kabanzi. Ilawula ukwakheka kwama-valve, ukukhetha kwezinto ezibonakalayo kanye nokuhlolwa kwengcindezi. I-ISO 6002 ingenye indinganiso yamazwe ngamazwe ehambisana ne-API 600 yamavalvu esango lensimbi yebhonethi eboshiwe, kuyilapho silandela indinganiso kazwelonke ye-GB/T 12234 yaseChina. Wonke lawa mazinga achaza usayizi, izidingo zokusebenza nokuphepha, ukuqinisekisa ukufakwa okufanele nokusebenza okuzinzile kwesikhathi eside.

Izimfanelo Ezibalulekile

Ungakwazi yini ukuchaza ukuthi i-API 600 ejwayelekile ihlanganisa ini?

I-API 600 iyindinganiso yezimboni ekhishwe yi-American Petroleum Institute. Isebenza kakhulu kumavalvu esango ensimbi yebhonethi eboshiwe, asetshenziswa kakhulu ezindaweni zokuhluza, amapayipi kawoyela negesi nezinye izimo zokusebenza ezinzima. Leli zinga lilawula ukukhethwa kwezinto, ukwakheka kwesakhiwo, izinqubo zokukhiqiza kanye nokuhlolwa okuhlukahlukene kwengcindezi nokuqina. Iqinisekisa ukuthi yonke i-valve ingakwazi ukumelana ngokuqinile nokucindezela okuphezulu, izinga lokushisa eliphezulu kanye nemidiya eyinkimbinkimbi ekusebenzeni kwensimu yangempela. Uma i-valve yesango ihlangana ne-API 600, yakhelwe ukuhlala ekusetheni okubalulekile, okufunayo.

I-WCB iluhlobo luni lwempahla yemizimba yamavalvu?

I-WCB iyibanga elivamile le-cast carbon steel ngaphansi kwe-ASTM A216, elifushane elithi “Weldable Grade B Cast Carbon Steel.” Kungenye yezinketho ezidume kakhulu zemizimba yama-valve ngoba ilinganisa amandla, ukushisela kanye nezindleko ezinhle kakhulu. I-WCB isebenzela ukusetshenziswa kwezimboni okuvamile, okuhlanganisa amanzi, uwoyela, igesi nemigqa yesitimu, futhi isingatha amazinga okushisa asuka ku -29°C kuya cishe ku-425°C. Iqinile, kulula ukuyifaka emimoyeni eyinkimbinkimbi, futhi isebenza ngohlu olubanzi lwezilinganiso zokucindezela.

Iluphi uhlobo lwe-valve yesango olusetshenziswa kakhulu embonini?

I-valve yesango le-wedge iwuhlobo oluvame kakhulu kumapayipi ezimboni. Inediski emise okwe-wedge eslayida phakathi kwezihlalo ezimbili ukuze ivule noma ivale ukugeleza, idale isivalo esiqinile lapho ivaleke ngokugcwele. Idizayini ilula futhi inokwethenjelwa, futhi isebenza kahle kuzo zonke izinhlobo zengcindezi nezinga lokushisa. Uzowathola ezikhungweni zokuhlanza amanzi, eziteshini zikagesi, ezindaweni zikawoyela negesi, nasezimbonini zamakhemikhali—yizona ezihamba phambili emisebenzini eminingi yokulawula engasebenzi.
