A umurongo wuzuye w'ikinyugunyugubiranga imiterere yuzuye mumubiri wa valve. Igishushanyo cyashizweho muburyo bwihariye bwo kwangirika.
"Urutonde rwuzuye" bivuze ko disiki idafunze gusa, ariko kandi intebe irakingiwe rwose, bigatuma ubwigunge bwuzuye hagati yibitangazamakuru nicyuma.
1. Ibikoresho bibiri bisanzwe
a. PTFE (polytetrafluoroethylene, parfluoroplastique) iringaniza ikinyugunyugu
b. Rubber umurongo wikinyugunyugu
| Ubwoko bw'ibikoresho: | Polytetrafluoroethylene (PTFE) umurongo | Ibikoresho bya reberi (urugero, EPDM, Viton, NBR) |
| Inzira | Molten PTFE / PFA isukwa muri dovetail groove kumubiri / disiki, bigera kumubano utagira ingano. | Ihita ihindagurika (ubushyuhe-bwakize) ku cyuma, ikora kashe ifatanye, yuzuye. |
| Ibyingenzi | - Kurwanya ruswa nziza cyane (irwanya aside hafi ya zose, ibishingwe, hamwe na solge organic) - Kurwanya ubushyuhe bwinshi (ubushyuhe bukomeza bugera kuri 180°C) - Coefficient de fraisement nkeya kandi idafite inkoni, ibereye itangazamakuru ryera cyane
| - Ubwiza buhebuje nibikorwa byiza byo gufunga (byoroshye kugera kuri zeru) - Igiciro gito hamwe no kurwanya kwambara kubitangazamakuru bitangirika - Kurwanya ubushyuhe buke (mubisanzwe -20°C kugeza 180°C, ukurikije ubwoko bwa reberi)
|
| Itangazamakuru rikoreshwa | Acide ikomeye (nka acide sulfurike na aside hydrochloric), ibishingwe bikomeye, ibishishwa kama, amazi meza cyane | amazi, amazi mabi, acide nkeya nishingiro, slurries, nibitangazamakuru byo murwego rwo kurya |
| Ibisanzwe | Inganda zikora imiti (kwimura aside na alkali), Inganda zimiti (ihererekanyabubasha ryinshi) | Gutunganya Amazi (gutunganya amazi mabi, amazi ya robine), Sisitemu ya HVAC, Inganda Ibiribwa n'ibinyobwa, Ubucukuzi bw'amabuye y'agaciro (transfert slurry) |
2. Intambwe Zirambuye Zitunganijwe kuri PTFE ikurikiranye na Disiki ya Valve
2.1 Gutegura ibyuma
a .. Tera cyangwa imashini ibyuma bya disiki yicyuma, urebe neza ko hejuru isukuye kandi idafite amavuta kandi yanduye.
b .. Kata ibinono (imiterere ya dovetail) hejuru yimbere kugirango utange amanota ya ankeri yo guterwa PTFE kandi wirinde kugwa.
2.2 Ifu ya PTFE Kubumba no gukora
a. Shira ingano yabazwe neza yifu ya PTFE (cyangwa premix) mubibumbano, shyiramo icyuma cyibinyugunyugu cyuma, hanyuma wongereho ifu ya PTFE.
b. Buhoro buhoro shyira vacuum (umunaniro) hamwe nigitutu (compression cyangwa gukanda isostatike) kugirango ukore urusoro rwatsi. Gushushanya Isostatike: Shira ifu mumazi hanyuma ushyireho igitutu kimwe kumpande zose (imiyoboro y'amazi) kugirango umenye imiterere imwe kandi yuzuye (porosity iri hasi ya <1%).
2.3 Gucumura no gukiza
a. Shira urusoro rwatsi mu ziko na sinter kuri 380 ° C mumasaha 5-24 (buhoro buhoro wongere ubushyuhe kugirango wirinde gucika).
b. Buhoro buhoro ubukonje bwicyumba kugirango PTFE ihindurwe kandi ihuze hamwe nicyuma, ikora igifuniko kidafite ikizinga (umubyimba ugenzurwa na 3-10mm, uhindurwa ukurikije ibihe bya vacuum).
2.4 Gukora no Kurangiza:
Koresha umusarani cyangwa imashini ya CNC kugirango ukore imashini yimbere ninyuma kugirango umenye neza ko disiki nintebe bihuye neza (kwihanganira birakomeye, urugero, ± 0.01mm).
2.5 Kugenzura Ubuziranenge no Kwipimisha:
a. Ibipimo by'ubunini: Menya neza ko byibuze byibuze 3mm, cyangwa nkuko byateganijwe.
b. Ikizamini cya Spark: 35.000 volt yo kugerageza gukomera (nta gusenyuka byerekana kwemerwa).
c. Ikizamini cya Vacuum / Imbaraga: Yigana imikorere yimikorere kugirango igenzure ibimeneka kandi byoroshye (ukurikije EN 12266-1 cyangwa API 598).
d. Ikizamini cya Conductivity (bidashoboka): Kurwanya Ubuso <10⁶Ω kubisabwa biturika.
3. Intambwe Zirambuye Zitunganijwe kuri EPDM ikurikiranye na Disiki
3.1 Gutegura ibyuma
a. Shira cyangwa ushireho intoki icyuma kugirango urebe neza neza.
b. Umucanga cyangwa imiti yubutaka hejuru (roughness Ra 3-6μm) kugirango uteze imbere EPDM.
3.2 Gushyira hamwe kwa EPDM no Gutegura
Ikirangantego cya EPDM kidafite umutekano (urupapuro cyangwa amazi) gishyirwa mubibumbano, bizengurutse icyuma. Ukoresheje compression ibumba cyangwa isuka, binganya gukwirakwiza ibice hejuru ya disiki ya valve kugirango ube umubiri wicyatsi. Komeza umubyimba wa mm 2-5, urebe neza ko uzengurutse impande za disiki.
3.3 Gukiza
Umubiri wicyatsi ushyirwa muri autoclave ugashyuha hamwe numwuka cyangwa umwuka ushushe (150-180 ° C, umuvuduko> 700 psi, mumasaha 1-4).
Uburyo bwo gukiza bwambukiranya kandi bukiza EPDM, mu buryo bwa shimi na mashini bubahuza nicyuma cyibyuma kugirango bibe bidafite umurongo, igice kimwe. Ongera ubushyuhe buhoro kugirango wirinde guhumeka ikirere cyangwa guturika.
3.4 Kurangiza imashini
Nyuma yo gukonjesha, kata impande zimbere ninyuma ukoresheje umusarani wa CNC kugirango urebe ko disiki nintebe bihuye neza (kwihanganira ± 0.05 mm). Kuraho reberi irenze urugero hanyuma ugenzure umwirondoro wacyo (Ni-Cu gutwikira birashoboka guhitamo kunanirwa kwambara).
3.5 Kugenzura ubuziranenge no gupima
a. Kwipimisha Ubunini hamwe na Adhesion: gupima uburebure bwa Ultrasonic (byibuze 2mm); Kwipimisha Tensile (imbaraga zishishwa> 10 N / cm).
b. Kugenzura imikorere: Bubble Tight Ikimenyetso Ikizamini (API 598 gisanzwe); Umuvuduko / Ikizamini cya Vacuum (PN10-16, kurwanya umuvuduko mubi).
c. Ikizamini cya Shimi / Gusaza: Kwibizwa muri aside na alkaline media, kugenzura kwaguka <5%; Gusaza cyane (120 ° C, 72h).
4. Igitabo cyo gutoranya
Imirongo ya PTFE irakwiriye kubitangazamakuru byangirika cyane (nka acide, alkalis, na solvents), mugihe imirongo ya EPDM ibereye kubitangazamakuru bishingiye kumazi, byoroheje (nk'amazi na acide acide). Shyira imbere guhuza imiti, ubushyuhe, igitutu, nigiciro kugirango uhindure porogaramu. Zhongfa Valve ikora ibinyugunyugu byuzuye umurongo hamwe na wafer, flange, hamwe na lug. Nyamuneka twandikire ibibazo byose.
