I-API Standard Forged Steel A182 F904L Uhlobo Oluntantayo Oluthambile Ivalvu Yebhola Elivaliwe

I-valve yebhola yensimbi efojiwe engu-F904L ikhethiwe, ifanele ukugxiliswa okuhlukahlukene kwe-sulfuric acid ngaphansi kuka-70 ℃, futhi inokumelana nokugqwala okuhle kunoma yikuphi ukugxila, izinga lokushisa, ne-asidi exubile ye-formic acid ngaphansi kwengcindezi evamile.

Njengensimbi engagqwali evamile, izindlela zokushisela zingasetshenziselwa ukushisela. Izindlela zokushisela ezivame ukusetshenziswa i-arc manual noma i-inert gas shielded welding. Induku yokushisela noma insimbi yocingo isekelwe ekwakhiweni kwezinto eziyisisekelo futhi inokuhlanzeka okuphezulu, okunesidingo esiphezulu sokuqukethwe kwe-molybdenum kunento eyisisekelo. Ukushisa kuqala akudingekile ngaphambi kokushisela, kodwa ekusebenzeni kwangaphandle okubandayo, ukugwema ukufingqa komphunga wamanzi, indawo ehlangene noma izindawo eziseduze zingashiswa ngokufanayo. Sicela uqaphele ukuthi izinga lokushisa lasendaweni akufanele lidlule ku-100 ℃ ukugwema ukunqwabelana kwekhabhoni kanye nokugqwala kwe-intergranular. Uma ushisela, kuhle ukusebenzisa amandla amancane ocingo, isivinini esiqhubekayo nesisheshayo. Ngemva kokushisela, ukwelashwa kokushisa ngokuvamile akudingeki. Uma kudingeka ukwelashwa kokushisa, kufanele kushiswe ku-1100-1150 ℃ bese kupholiswa ngokushesha.

Ukusebenza komshini:

Izici zomshini zifana nezinye izinsimbi ezingenasici ze-austenitic, futhi kukhona ukuthambekela kokunamathela kwethuluzi nokusebenza lukhuni phakathi nenqubo yokwenza imishini. Amathuluzi okusika ama-angle aqinile kufanele asetshenziswe, ngamafutha amakhemikhali kanye ne-chlorinated njengesipholisi sokusika. Imishini kanye nenqubo kufanele kusekelwe ekunciphiseni ukuqina komsebenzi. Isivinini sokusika kancane kanye nenani lokudla kufanele kugwenywe ngesikhathi sokusika.

I-valve yebhola elintantayo eyenziwe ngensimbi inomthamo omncane, isisindo esilula, isakhiwo esilula, nomsebenzi ontantayo wamahhala, ongaqinisekisa ukubekwa uphawu okuhle; Ihambisana nesakhiwo esihlangene kanye nokushintsha okusheshayo, i-valve ingavalwa futhi i-medium yepayipi inganqanyulwa ngokuyizungezisa ama-degree angu-90; Ububanzi bomzila oyindilinga bufana nepayipi, elinokumelana nokugeleza okuphansi kanye nomthamo wokugeleza okuphezulu; Isiqu se-valve sifakwe phansi, esivimbela izingozi ezibangelwa ukubhoboza isiqu se-valve futhi siqinisekise ukusetshenziswa okuphephile. Izici zokuklama zesakhiwo esiyinhloko se-valve yebhola elintantayo lensimbi:

1. Ukuklanywa kwesiqu se-valve esandisiwe

Isiqu se-valve se-valve yebhola elintantayo sakhiwe ngesakhiwo se-valve esinwetshiwe. Idizayini yesakhiwo se-valve esinwetshiwe ihloselwe kakhulu ukugcina isakhiwo sebhokisi lokupakisha i-valve kude nendawo enezinga lokushisa eliphansi, ukuqinisekisa ukuthi ibhokisi lokupakisha kanye nomkhono wokucindezela kusetshenziswa emazingeni okushisa avamile ukuvimbela ukushisa okubandayo kanye nesithwathwa somqhubi. Ngesikhathi esifanayo, iphinde ivimbele ukusebenza kokuvalwa kokupakisha ekunciphiseni futhi kwandise impilo yayo yesevisi.

2. Idizayini ye-Drip Board

Idizayini ye-drip plate iyamukelwa esakhiweni sesiqu se-valve esinwetshiwe, esingavimbela amanzi okujiya ukuthi ahwamuke futhi agelezele endaweni yokufakwa ngaphakathi. Ngesikhathi esifanayo, ingaqinisekisa ngokuphumelelayo indawo yokusebenza yebhokisi lokupakisha, ngaleyo ndlela igweme imiphumela eminingi emibi.

3. Umklamo wokuvikela umlilo

Ngenxa yokuthi ama-valve ebhola ngokuvamile asetshenziswa emithonjeni evuthayo neqhumayo, umklamo wokuvikela umlilo ubalulekile. Isakhiwo sophawu olumbaxambili sendandatho yokuvala emise okwezindebe kanye ne-gasket yesilonda esivunguzayo isetshenziswa ekuxhumekeni phakathi kwekhava yevalvu, kanye nesakhiwo esikabili sendandatho yokuvala emise okwezindebe kanye nokupakishwa kwegraphite kusetshenziswa ebhokisini lokupakisha. Lapho kuvela umlilo, indandatho yokuvala emise okwezindebe iyancibilika futhi ihluleke, futhi i-gasket ephendukayo kanye nesigcwalisi segraphite kudlala indima enkulu yokuvala.

4. I-Anti static design

Ngesenzo esisebenzayo seziphethu eziphikisana ne-static namabhola ensimbi, ibhola, isiqu se-valve, nomzimba we-valve kuxhumene, kwakha isekethe yokuqhuba. Lokhu kungadlulisela amashaji akhiqizwe i-valve ngesikhathi sokuvula nokuvala, ngaleyo ndlela kugweme ukunqwabelana kukagesi omile ohlelweni lwamapayipi nokwandisa ukuphepha kwesistimu. Ukumelana phakathi kwesiqu se-valve, ibhola, kanye nomzimba we-valve kufanele kukalwe kusetshenziswa i-DC amandla angeqi ku-12V. Ukulinganisa kufanele kwenziwe ku-valve eyomile ngaphambi kokuhlolwa kwengcindezi, futhi ukumelana akufanele kudlule i-10 ohms.
