I-valve yokuphepha yayivame ukubhekana nesinqumo sephutha kanye nemiyalo yokusetshenziswa kwe-fluorine lining valve

I-valve yokuphepha yayivame ukubhekana nokwahlulela okunephutha nokulungiswa
1. Ungavuli lapho ukucindezela kucacisiwe
Isizathu salesi simo ukuthi ingcindezi eqhubekayo ayilungile. Ukucindezelwa kwentwasahlobo noma ukuma kwesando kufanele kulungiswe kabusha; I-disc inamathela esihlalweni. Ivalvu yokuphepha kufanele ihlale ihlolwa komoya noma amanzi; I-valve yokuphepha yohlobo lwe-Lever ibambekile noma isando esindayo siyasuswa. Isisindo kufanele silungiswe futhi i-lever kufanele ihambe ngokukhululeka.
2, ngaphansi kwengcindezi eshiwo evulekile
Ingcindezi enkulu ayilungile; Ukuguga kwentwasahlobo nokunwebeka kwentwasahlobo kuyancipha. Isikulufu sokulungisa noma isiphethu kufanele siqiniswe kahle.
3. I-disc ayibuyeli esihlalweni ngemva kokukhishwa
Lokhu kubangelwa ikakhulukazi isiqu sokugoba entwasahlobo, indawo yokufaka idiski ayilungile noma ibambekile. Kufanele ihlanganiswe kabusha.
4, i-disc frequency jump noma ukudlidliza
Isizathu esiyinhloko ukuthi ukuqina kwentwasahlobo kukhulu kakhulu. Intwasahlobo enokuqina okufanele kufanele isetshenziswe esikhundleni salokho; Umbuthano wokulungisa awulungiswanga kahle, ukuze ukucindezela kuphezulu kakhulu. Ukuma kwendandatho yokulungisa kufanele kulungiswe kabusha; Ukuphikiswa kwepayipi lokukhipha kukhulu kakhulu, okuholela ekucindezelweni okukhulu kokukhishwa emuva. Ukumelana namapayipi okulahla kufanele kuncishiswe.
5. Ukucindezela kuyaqhubeka nokukhuphuka ngemva kokukhathala
Lokhu kungenxa yokuthi ukukhethwa kokukhishwa kwe-valve yokuphepha kwe-Xiaoping ukukhishwa kokuphepha kwemishini, kufanele kuphinde kukhethwe i-valve yokuphepha efanele; Umugqa ophakathi kwe-stem noma ukugqwala kwentwasahlobo, ukuze i-disc ingavulwa ekuphakameni okufanele, kufanele iphinde ihlanganiswe isiqu noma ithathe indawo yasentwasahlobo; Uma ukusika kwepayipi yokukhipha kunganele, ipayipi yokukhipha ngokuhambisana nendawo yokukhipha ephephile kufanele yamukelwe.
6, ukuvuza
Ngaphansi kwengcindezi evamile yokusebenza kwemishini, ukuvuza phakathi kwediski nendawo yokuvala yesihlalo kudlula izinga elivumelekile. Isizathu siwukuthi: kukhona ukungcola phakathi kwe-valve disc kanye nendawo yokuvala isihlalo. Ungasebenzisa i-wrench yokuphakamisa ukuvula i-valve izikhathi eziningana, ukungcola kugezwe; Ukulimala kwendawo yokuvala. Kufanele ilungiswe ngokugaya noma ukugaya ngemva kokuphenduka ngokwezinga lomonakalo. Ukugoba kwesiqu, ukutsheka, noma ukuchezuka kwe-lever ne-fulcrum, okuholela ekungaqondisweni kahle kwe-spool ne-disc. Kufanele ihlanganiswe kabusha noma ishintshwe; Ukunwebeka kwentwasahlobo kunciphisa noma kulahlekelwa ukunwebeka. Izinyathelo ezinjengokushintsha intwasahlobo kanye nokulungisa kabusha ingcindezi yokuvula kufanele kuthathwe.
Imiyalo yokusetshenziswa kwama-valve ane-fluorine anemigqa
Izici eziyinhloko ze-valve ene-fluorine lined:
Okokuqala, ukusebenza kwamakhemikhali e-fluorine lined valve:
Ukumelana nokuguga kwe-Atmospheric: ukumelana nemisebe kanye nokungena kancane kancane: ukuchayeka isikhathi eside emkhathini, indawo engaphezulu nezakhiwo zihlala zingashintshile.
Ukungashi: Inkomba yomkhawulo we-oxygen ingaphansi kwama-90.
Ukumelana ne-Acid ne-alkaline: ayincibiliki kuma-asidi aqinile, izisekelo kanye nezincibilikisi zemvelo.
Ukumelana ne-oxidation: ukumelana nokugqwala ngama-oxidants aqinile.
Okubili, izici zokusebenza kwamavalvu ane-fluorine:
Ukusebenza: Izinga lokushisa elimaphakathi lokusebenza: -100℃~-150℃
Ingcindezi yokusebenza emaphakathi: ingcindezi enhle: 2.5mpa, ingcindezi engafanele ekamelweni lokushisa 70KPa
Ukumelana nokugqwala: ipayipi eliyinhlanganisela yensimbi ye-PTFE, ngaphezu kwe-lithium yensimbi encibilikisiwe, i-potassium, i-sodium, i-chlorine trifluoride, i-oxygen trifluoride ekushiseni okuphezulu, izinga lokugeleza okuphezulu kwe-fluorine ye-fluorine, ingamelana cishe nayo yonke imidiya yamakhemikhali, kuhlanganise ne-nitric acid egxilile kanye ne-aqua royalty corrosion. , ingasebenza ekushiseni kuka-230℃-250℃ isikhathi eside. Insimbi ye-polyvinylidene fluoride noma enye ipayipi eliyinhlanganisela ye-vinylidene fluoride, i-halogen, i-halogenated hydrocarbons, ama-oxidants aqinile, i-asidi ebilayo, i-alkali, izinhlobonhlobo zezinyibilikisi eziphilayo zinokumelana nokugqwala okuhle, kodwa azimelani nentuthu ye-sulfuric acid, i-sulfuric acid egxilile ne-nitric acid, ama-ketones. , ama-esters, ama-amine kanye nezinga lokushisa eliphakeme le-ejenti ye-sulfonating corrosion ngaphezu kuka-90℃.
Izinzuzo eziyinhloko ze-valve ene-fluorine lined:
Izinga lokushisa eliphakeme elimelana nezinga lokushisa elifinyelela ku-250 ℃
Ukumelana nokushisa okuphansi nokuqina okuhle kwemishini; Ngisho nalapho izinga lokushisa lehlela ku -196℃, ubude obungu-5% bungagcinwa.
Ukumelana nokugqwala kumakhemikhali amaningi nezincibilikisi, okubonisa inertia, i-asidi eqinile ne-alkali, amanzi nezinhlobonhlobo zezinyibilikisi eziphilayo.
Ukumelana nesimo sezulu nempilo yokuguga kumapulasitiki.
I-lubrication ephezulu i-coefficient ephansi yokungqubuzana kwezinto eziqinile.
Ukunganamatheli ukuqina okuncane kwendawo ezintweni eziqinile, akunamatheli kunoma iyiphi into.
Okungeyona ubuthi nge-inertia ye-physiological, engenabuthi ezintweni eziphilayo.
Izinhlelo zokusebenza eziyinhloko zevalvu ene-fluorine:
I-Fluorine LINED VALVE IFANELE izinga lokushisa eliphezulu igesi egqwala kakhulu kanye noketshezi, ezinye izinhlobo zepayipi eliyinhlanganisela yepulasitiki yensimbi kanye nepayipi lensimbi alikulungele ukudlulisa okuphakathi nendawo, okuyinkimbinkimbi yensimbi ye-PTFE. Ipayipi eliyinhlanganisela ye-polyvinylidene fluoride yensimbi ilungele ukudlulisa imidiya egqwalayo enezinga lokushisa elisebenzayo ukusuka ku--40 ℃ ukuya ku-+150 ℃.
Isingeniso sobuchwepheshe bokucubungula i-fluorine lining valve
A, tetrafluoroethylene (PTFE)- sodium naphthalene solution bonding method
I-Polytetrafluoroethylene (PTFE) - indlela yokwelapha isixazululo se-sodium naphthalene: ukwelashwa kwesixazululo se-sodium naphthalene se-fluorine equkethe izinto, ikakhulukazi ngoketshezi olubolayo kanye ne-PTFE plastic chemical reaction, kudabula ingxenye yama-athomu e-fluorine ebusweni bento, ngakho-ke ngaphezulu kwesobunxele. ungqimba lwe-carbonized kanye namaqembu athile amhlophe. I-spectrum ye-infrared ibonisa ukuthi ukwethulwa kweqembu le-hydroxyl, iqembu le-carbonyl ne-unsaturated bond namanye amaqembu e-polar ebusweni, la maqembu angandisa amandla angaphezulu, anciphise i-Angle yokuxhumana, athuthukise ukumanzisa, kusukela kunzima kuya kokunamathela. Lena indlela ephumelela kakhulu futhi evame ukusetshenziswa phakathi kwazo zonke izindlela ezifundwayo njengamanje. I-sodium naphthalene tetrahydrofuran ngokuvamile isetshenziswa njengesixazululo sokugqwala. Inqubo yokuhlanganisa imi kanje:
(1) Ukulungiswa kwesixazululo sokwelashwa: engeza inani elithile lensimbi ye-sodium kusixazululo se-tetrahydrofuran ne-naphthalene, ingxenye enkulu yensimbi ye-sodium ilawulwa ku-3% -5%, inyakaze ekamelweni lokushisa cishe amahora angu-2, kuze kube umbala ikhambi livela elimnyama noma elimnyama;
(2) ucezu lokusebenzela lwe-PTFE oluzophathwa lwacwiliswa kusixazululo cishe i-5 ~ 10min, bese lucwiliswa ku- ** isixazululo se-3 ~ 5 min;
(3) Khipha i-workpiece esixazululweni, ugeze ngamanzi bese uyibeka emthunzini ukuze yome ngokwemvelo;
(4) Khetha i-epoxy resin, i-silicone noma i-polyurethane njenge-adhesive, ehlanganiswe ngokulinganayo endaweni ephathwayo ukuze iboshwe futhi iboshwe ngokushesha, ime ku-24 ~ 30℃ i-24h, ungakwazi ukubopha ngokuqinile.
