API Standard Forged Steel A182 F904L Uhlobo oludadayo Soft Ivalve yeBhola etywiniweyo

I-valve yebhola yentsimbi ekhandiweyo ye-F904L ikhethiwe, ifanelekile kwiintlobo ezahlukeneyo ze-asidi ye-sulfuric engaphantsi kwe-70 ℃, kwaye inokumelana ne-corrosion elungileyo kuyo nayiphi na i-concentration, ubushushu, kunye ne-asidi edibeneyo ye-asidi ye-formic phantsi koxinzelelo oluqhelekileyo.

Njengentsimbi eqhelekileyo engenasici, iindlela ezahlukeneyo zokuwelda zingasetyenziselwa ukuwelda. Iindlela ze-welding ezisetyenziswa ngokuqhelekileyo zi-arc manual okanye i-inert gas shielded welding. Intonga ye-welding okanye i-wire metal isekelwe ekubunjweni kwezinto ezisisiseko kwaye inobunyulu obuphezulu, kunye nemfuno ephezulu yomxholo we-molybdenum kunezinto ezisisiseko. Ukufudumala ngokuqhelekileyo akuyimfuneko phambi kwe-welding, kodwa kwimisebenzi ebandayo yangaphandle, ukuphepha ukunyuswa komphunga wamanzi, indawo edibeneyo okanye iindawo ezikufutshane zinokufudumeza ngokufanayo. Nceda uqaphele ukuba ubushushu bendawo akufuneki budlule kwi-100 ℃ ukunqanda ukuqokelelana kwekhabhoni kunye ne-intergranular corrosion. Xa u-welding, kuyacetyiswa ukuba usebenzise amandla amancinci ocingo, ukuqhubela phambili kunye nokukhawuleza kwesantya. Emva kwe-welding, unyango lobushushu alufunwa ngokubanzi. Ukuba unyango lobushushu luyafuneka, kufuneka lufudunyezwe kwi-1100-1150 ℃ kwaye lupholiswe ngokukhawuleza.

Ukusebenza komatshini:

Iimpawu ze-machining zifana nezinye i-austenitic stainless steels, kwaye kukho ukuthambekela kokunamathela kwesixhobo kunye nokusebenza nzima ngexesha lenkqubo yokwenza. Kufuneka kusetyenziswe izixhobo zokusika i-angle eqinileyo, kunye neekhemikhali kunye neoyile ekloriniwe njengesipholisi sokusika. Isixhobo kunye nenkqubo kufuneka zisekelwe ekunciphiseni ukuqina komsebenzi. Isantya esincinci sokusika kunye nenani lesondlo kufuneka ligwenywe ngexesha lokusika.

- Imilinganiselo yoxinzelelo ukusuka kwiKlasi ye-150LB ukuya kwi-600LB (PN10 ukuya kwi-PN100).

- Ukwahlula isakhiwo somzimba 2-pc okanye 3-pc.

- RF, RTJ, BW ekupheleni.

-Idizayini epheleleyo okanye encitshisiweyo yokuzala.

-Imowudi yokuqhuba inokuba yimanual, yombane, ipneumatic, okanye uhlobo lwesiqu esingenanto kunye ne-ISO 5211 flange ephezulu yee actuators zakho.

- Izinto eziqhelekileyo ezifana ne-A105, i-A182 F304, i-A182 F316L, njl kunye nezinto ezikhethekileyo ze-alloy eziphezulu ezifana ne-A182 F904L, A182 F51, A493 R60702, B564 N06600, B381 Gr. F-2, njl.

Ivalve yebhola edadayo eyenziwe ngentsimbi inomthamo omncinci, ubunzima obulula, isakhiwo esilula, kunye nomsebenzi odadayo okhululekileyo, onokuqinisekisa ukutywinwa okulungileyo; Ebonisa i-compact structure kunye nokutshintsha ngokukhawuleza, i-valve inokuvalwa kwaye i-pipeline medium inokunqunyulwa ngokuyijikeleza i-90 degrees; Ububanzi bomjelo we-spherical bufana nelombhobho, kunye nokumelana nokuhamba okuphantsi kunye nomthamo ophezulu wokuhamba; Isiqu sevalve sibekwe ezantsi, nto leyo ethintela iingozi ezibangelwa kukugqobhoza kwesikhondo sevalve kwaye iqinisekise ukusetyenziswa ngokukhuselekileyo. Iimpawu zoyilo lwesakhiwo esiphambili sevalve yebhola edadayo yentsimbi:

1. Uyilo lwesiqu sevalve eyandisiweyo

Isiqu sevalve yevalve yebhola edadayo siyilwe ngesakhiwo sesiqu sevalve eyandisiweyo. Uyilo lwesakhiwo se-valve eyandisiweyo yesiqu sijolise ikakhulu ekugcineni i-valve yokupakisha ibhokisi yesakhiwo kude nendawo yobushushu obuphantsi, ukuqinisekisa ukuba ibhokisi yokupakisha kunye nomkhono woxinzelelo zisetyenziswa kumaqondo obushushu aqhelekileyo ukukhusela ubushushu obubandayo kunye neqabaka yabaqhubi. Kwangaxeshanye, ikwathintela ukusebenza kokutywinwa kokupakishwa ekunciphiseni kwaye kwandise ubomi bayo benkonzo.

2. Uyilo lweBhodi yeDriphu

Uyilo lwepleyiti yedriphu yamkelwa kulwakhiwo lwesikhondo sevalve eyandisiweyo, enokuthintela amanzi ajikijelwayo ekubeni abe ngumphunga kwaye aqukuqele kwindawo yokugquma. Ngexesha elifanayo, inokuqinisekisa ngokufanelekileyo indawo yokusebenza yebhokisi yokupakisha, ngaloo ndlela igwema imiphumo emibi emininzi.

3. Uyilo lokukhusela umlilo

Ngenxa yokuba iivalvu zebhola zisetyenziswa ngokubanzi kwimidiya enokutsha kunye neziqhumayo, uyilo lokukhusela umlilo lubalulekile. Ulwakhiwo oluphindwe kabini lomsesane wokutywina omile okwemilebe kunye negasket yenxeba elijikelezayo isetyenziswa kuqhagamshelo phakathi komzimba wevalve kunye nesigqubuthelo sevalvu, kunye nesakhiwo sokutywina esiphindwe kabini seringi yokutywina emise okwemilebe kunye nokupakishwa kwegraphite kusetyenziswa kwibhokisi yokupakisha. Xa kuqhambuka umlilo, ikhonkco lokutywina elimilebe elimilebe liyanyibilika lize lisilele, kwaye igaskithi ejikajikayo kunye negraphite filler zidlala indima ephambili yokutywina.

4. Uyilo lwe-Anti static

Ngesenzo esisebenzayo semithombo ye-anti-static kunye neebhola zentsimbi, ibhola, isiqu sevalve, kunye nomzimba wevalvu ziyadibana, zenza isekethe yokuhambisa. Oku kunokudlulisa iindleko eziveliswa yi-valve ngexesha lokuvula nokuvalwa, ngaloo ndlela ugweme ukuqokelelwa kombane ongatshintshiyo kwinkqubo yepayipi kunye nokwandisa ukhuseleko lwenkqubo. Ukumelana phakathi kwesiqu sevalve, ibhola, kunye nomzimba wevalvu kufuneka kulinganiswe kusetyenziswa umbane weDC ongagqithiyo kwi-12V. Umlinganiselo kufuneka uqhutywe kwi-valve eyomileyo ngaphambi kovavanyo loxinzelelo, kwaye ukuchasana akufanele kudlule i-10 ohms.
