I-Forged Steel Body, Ivalvu Yebhola Elicindezela Kakhulu Yamafutha, Igesi Namapayipi Amakhemikhali

Iza neziphetho ze-flange ezijwayelekile. Yingakho onjiniyela nabaphathi bezitshalo bevame ukuyikhethela imigqa ebaluleke kakhulu yokucindezela okukhulu - kulula ukuyifaka esizeni, kulula ukuyinakekela, futhi i-flange ehlangene ibamba uphawu oluthembekile.

Izimfanelo Ezibalulekile

Forged Steel Body Construction

Umzimba wethu owenziwe nge-valve yebhola ene-flanged ukhiqizwa nge-solid steel billet ngokufoja, hhayi ukuphonsa isihlabathi. Inqubo yokubumba icwenga ukwakheka okusanhlamvu kwangaphakathi kwensimbi, iqede ukukhubazeka okujwayelekile kokuphonsa okufana ne-porosity, imigodi enciphayo kanye nokufakwa kwesihlabathi. Lokhu kunikeza umzimba we-valve amandla aphezulu kakhulu okudonsa, ukumelana nomthelela kanye nokumelana nokushaqeka kwengcindezi.

Amavalvu okusakaza asebenza kahle kumapayipi avamile, anengozi encane. Kodwa ngengcindezi ephezulu, umthwalo we-cyclic kanye nesevisi ebaluleke kakhulu yokuphepha, ukwakhiwa komgunyathi kunciphisa kakhulu ingozi yokuqhekeka komzimba kanye nokuvuza okuyinhlekelele. Konke ukukhanga okungaphekiwe kungalandelelwa ngezinombolo zokushisa, futhi izitifiketi zokuhlolwa kwezinto ezigcwele (MTC) ziyatholakala uma ucelwa.

Yiziphi izimboni nabezindaba ezifanele le valve yebhola eyenziwe ngomgunyathi?

Le valve yebhola eyenziwe nge-flanged yamukelwa kabanzi kuwo wonke uwoyela negesi, ukudluliswa kwegesi yemvelo, ukucubungula amakhemikhali, izindawo zokuhlanza, ukukhiqiza ugesi, amapayipi asizayo aphesheya kwezilwandle, amasistimu omjovo wamanzi anengcindezi ephezulu kanye nezitshalo zikamanyolo.

Isebenza ngokuthembekile oketshezini oluhlanzekile, umoya ocindezelweyo, igesi yemvelo, i-nitrogen, i-hydrocarbon kanye nohlu olubanzi loketshezi lwenqubo olungancibiliki. Ngokukhetha okufanelekile kwe-trim kanye nesihlalo, ingakwazi futhi ukuphatha imidiya eyonakalisa kancane. Idizayinelwe isevisi yokuhlukanisa, ilungele amapayipi adinga ukuvalwa ngesikhathi sokulungiswa okujwayelekile noma ukuvalwa kwesimo esiphuthumayo.

Flanged Connection Design

Uxhumano lwe-Flanged luyisinqumo esijwayelekile samaphrojekthi ezimboni ezisindayo. Ubuso be-flange obujwayelekile (i-RF / RTJ ngokuzikhethela) bufana nezindinganiso ze-ASME B16.5 noma ze-GB flange. Ngesikhathi sokufakwa, abasebenzi besayithi bangakwazi ukuqondanisa kalula izimbobo ze-bolt, babeke ama-gaskets futhi baqinise ama-bolts ngaphandle kwemishini ekhethekile yokushisela.

Inzuzo enkulu iza ngesikhathi sokulungiswa kabusha: ungakwazi ukukhipha i-valve epayipini ngokushesha ngaphandle kokusika ipayipi. Lokhu kunciphisa kakhulu isikhathi sokuphumula lapho udinga ukuhlola abangaphakathi, ukushintsha izihlalo noma ukushintshanisa i-valve yonke. Uma kuqhathaniswa neziphetho ezinentambo, amalunga ane-flanged asekela izilinganiso zokucindezela eziphakeme kakhulu; uma kuqhathaniswa neziphetho ezishiselwe, inika amandla ukuqaqa okuphindaphindekayo.

Ingabe le valve yebhola efojiwe ingakwazi ukubhekana nezinga lokushisa elivamile kanye nokushintshashintsha kwengcindezi?

Amapayipi ezimboni ngokuvamile abona ukushintsha kwengcindezi yokusebenza kanye nezinga lokushisa ngesikhathi sokuqalisa, ukuvala shaqa kanye nezinguquko zokulayisha. Umzimba wensimbi efojiwe ugcina ukusebenza okuzinzile ngaphansi kwalezi zimo zomjikelezo.

Sifanisa iphakheji yokuvala nemvilophu yakho esebenzayo. I-PTFE, i-RPTFE kanye nezinketho ze-metal-to-metal hard seal ziyatholakala. Izihlalo ezithambile zihlinzeka ngokuvaleka kwebhamuza elingavuzi uziro ngesevisi ehlanzekile; izihlalo zensimbi zifanele izinga lokushisa eliphezulu noma izidingo eziphephile emlilweni. Idizayini yokupakisha isiqu ilawula ukukhishwa kwekhabhoni, ihlangabezana nezidingo ezijwayelekile zemvelo zesevisi ye-hydrocarbon.

Izinketho Zokubalulekile Zomzimba & Ukunquma Kwangaphakathi

Sigcina iphothifoliyo yezinto ezibanzi ukuze ifane nezidingo zakho zokugqwala okumaphakathi nezinga lokushisa:

- Carbon steel: A105 / A105N, ilungele igesi engagqwali ephezulu namafutha

- Insimbi engagqwali ye-Austenitic: F304, F316L, yoketshezi oludlayo olujwayelekile

- I-Duplex & super duplex: F51, F53, F57, NS2609, NS2607 yamanzi olwandle, i-brine nemidiya ene-acidic equkethe i-H₂S

Futhi singakwazi ukwenza ngokwezifiso ibhola, isiqu kanye nezinto zokuhlala. Vele wabelane ngevelu yakho emaphakathi, ye-pH kanye nebanga lokushisa elisebenzayo, futhi ithimba lethu lonjiniyela lizoncoma inhlanganisela yokunquma engabizi kakhulu.

Usayizi, Ikilasi Lokucindezela & Idizayini Ongayikhetha

Osayizi bamboza i-DN15 ~ DN300 kanye ne-bore emikhudlwana uma uceliwe. Izilinganiso zokucindezela zifaka i-PN16, PN40, PN63, PN100, PN160, kanye ne-ASME Class 150, 300, 600, 900, 1500.

Ubuso be-Flange butholakala ku-Raiseed Face (RF) kanye ne-Ring Type Joint (RTJ). Imiklamo ephephile emlilweni kanye ne-anti-static inganikezwa ngesicelo.

Ungakhetha ibhore eligcwele noma elincishisiwe. Ukusikeka okuphelele kokugeleza kokugeleza futhi kuvumela ukungulube. Isibhobo esincishisiwe sincane futhi sivumelana nesabelomali uma ukungulube kungadingeki.

Izinketho Zokusebenza

Sinikeza izitayela ezimbalwa zokusebenzisa ukuze zilingane nezidingo zesayithi lakho:

- Isibambo se-Lever: esithengekayo futhi silula, silungele ukusebenza ngesandla lapho i-valve kulula ukufika kuyo

- Umqhubi wegiya: kumavalvu amakhulu abhorekile noma anetorque ephezulu, kwenza ukuvula nokuvala kube lula kakhulu

- I-actuator ye-pneumatic: vula futhi ivale ngokushesha. Ihambisana nama-valve e-solenoid futhi ikhawulele ukushintsha kokulawula okuzenzakalelayo

- I-actuator kagesi: ifanele ukusebenza kude, ukulawula ukugeleza, noma izindawo ezingenawo umoya ocindezelweyo

Singakwazi futhi ukwengeza isondo lesandla kumavalvu acushiwe. Lokhu kukuvumela ukuthi usebenzise i-valve mathupha uma amandla noma ukunikezwa komoya kwehluleka.

Imaphi amazinga okuhlola namadokhumenti ongawathola kithi?

Yonke i-valve yebhola efojiwe ene-flanged ihlolwa i-hydrostatic yegobolondo kanye nokuhlolwa kokuvuza kwesihlalo ngaphambi kokupakisha. Silandela i-API 6D, ASME B16.5 kanye namazinga emboni ahlobene. Ukuhlolwa kofakazi benkampani yangaphandle kusekelwa uma kudingwa yincazelo yephrojekthi yakho.

Singakunikeza wonke amaphepha owadingayo: izitifiketi zokuhlola izinto ezibonakalayo, imibiko yokuhlolwa, imidwebo yobukhulu kanye namamanuwali okusebenza. Yonke i-valve inesitembu esicacile nenombolo yayo yokushisa, ibanga lempahla, usayizi nesilinganiso sokucindezela, ukuze ukwazi ukulandelela impahla yayo nomlando wokukhiqiza ngaphandle kwenkinga.
