Umutekano wumutekano wakunze guhura nikibazo cyo gufata neza no gufata neza fluor lining valve ikoresha amabwiriza

Umutekano wumutekano wakunze guhura namakosa no kubungabunga
1. Ntukingure mugihe igitutu cyerekanwe
Impamvu yibi bintu nuko igitutu gihoraho kidahwitse. Gucomeka kw'isoko cyangwa umwanya w'inyundo bigomba guhindurwa; Disiki ifata intebe. Umuyoboro wumutekano ugomba guhora wipimisha ikirere cyangwa amazi; Ubwoko bwumutekano wibikoresho bya lever bifatanye cyangwa inyundo iremereye irimurwa. Uburemere bugomba guhindurwa kandi leveri igomba kugenda mubuntu.
2, munsi yigitutu cyagenwe gifunguye
Umuvuduko wingenzi ntabwo ari ukuri; Imvura yo gusaza yimvura igabanuka. Imashini ihindura cyangwa isoko igomba gukomera neza.
3. Disiki ntisubira ku ntebe nyuma yo gusohoka
Ibi ahanini biterwa nimpeshyi igoramye, imyanya yo gushiraho disiki ntabwo ikwiye cyangwa ifatanye. Igomba guteranyirizwa hamwe.
4, gusimbuka inshuro nyinshi cyangwa kunyeganyega
Impamvu nyamukuru nuko gukomera kwamasoko ari binini cyane. Isoko hamwe no gukomera bikwiye gukoreshwa aho; Uruziga rwo guhindura ntabwo rwahinduwe neza, kuburyo igitutu ari kinini. Umwanya wimpeta ihindura ugomba guhindurwa; Kurwanya imiyoboro isohoka ni nini cyane, bikaviramo umuvuduko mwinshi winyuma. Kurwanya imiyoboro y'amazi bigomba kugabanuka.
5. Umuvuduko ukomeje kwiyongera nyuma yo kunanirwa
Ibi biterwa cyane cyane nuko guhitamo umutekano wibikoresho byimurwa Xiaoping ibikoresho byo kurekura umutekano, bigomba kongera gutoranywa neza na valve yumutekano; Umurongo wo hagati cyangwa ingese, kugirango disiki idashobora gukingurwa muburebure bukwiye, igomba guteranyirizwa hamwe cyangwa gusimbuza isoko; Niba umuyoboro uva mu muyoboro udahagije, hagomba kwakirwa umuyoboro uva mu kirere ujyanye n’ahantu ho gusohora umutekano.
6, kumeneka
Munsi yumuvuduko usanzwe wibikoresho, kumeneka hagati ya disiki hamwe nubuso bwa kashe yintebe birenze urwego rwemewe. Impamvu ni: hari umwanda hagati ya disiki ya valve nubuso bwa kashe yintebe. Urashobora gukoresha umugozi wo guterura kugirango ufungure valve inshuro nyinshi, umwanda wogejwe; Ibyangiritse hejuru yikimenyetso. Igomba gusanwa no gusya cyangwa gusya nyuma yo guhinduka ukurikije urugero rwibyangiritse. Igiti kigoramye, kigoramye, cyangwa lever na flcrum gutandukana, bikaviramo guhuzagurika na disiki. Bikwiye guteranyirizwa hamwe cyangwa gusimburwa; Imvura yo mu mpeshyi igabanuka cyangwa igatakaza ubukana. Hagomba gufatwa ingamba nko gusimbuza isoko no guhindura igitutu cyo gufungura.
Amabwiriza yo gukoresha fluor itondekanye neza
Ibintu nyamukuru biranga fluor itondekanye:
Ubwa mbere, fluor itondekanye ya valve ikora imiti:
Kurwanya gusaza kwa Atmospheric: kurwanya imirasire hamwe no gutembera gake: kumara igihe kirekire ikirere, ubuso hamwe nimiterere ntibigihinduka.
Kudakongoka: indangagaciro ya ogisijeni iri munsi ya 90.
Kurwanya aside na alkaline: kudashonga muri acide ikomeye, shingiro hamwe na solge organic.
Kurwanya Oxidation: kurwanya ruswa na okiside ikomeye.
Babiri, fluor umurongo wa valve ukora:
Imikorere: Ubushyuhe bwo hagati: -100 ℃ ~ -150 ℃
Umuvuduko wo gukora hagati: umuvuduko mwiza: 2.5mpa, umuvuduko mubi mubushyuhe bwicyumba 70KPa
Kurwanya ruswa: umuyoboro wa PTFE wibumbiye hamwe, usibye lithium yicyuma gishongeshejwe, potasiyumu, sodium, chlorine trifluoride, ogisijeni trifluoride ku bushyuhe bwinshi, fluor fluorine y’amazi menshi, irashobora kurwanya ibitangazamakuru hafi ya byose bya chimique, harimo aside nitricike yibanze hamwe na ruswa ya ruswa. , irashobora gukora mubushuhe bwa 230 ℃ -250 ℃ igihe kirekire. Icyuma cya polyvinylidene fluor cyangwa ikindi cyuma cya vinylidene fluoride, halogen, hydrocarbone ya halogene, okiside ikomeye, aside itetse, alkali, imiti itandukanye yumubiri ifite imbaraga zo kurwanya ruswa, ariko ntishobora kurwanya umwotsi wa sulfurike, aside irike ya sulfurike na aside nitricike, ketone , esters, amine hamwe nubushyuhe bwo hejuru sulfonating agent ruswa hejuru ya 90 ℃.
Ibyiza byingenzi bya fluor itondekanye:
Ubushyuhe bwo hejuru burwanya ubushyuhe bugera kuri 250 ℃
Ubushyuhe buke hamwe nubukanishi bwiza; Ndetse iyo ubushyuhe bugabanutse kuri -196 ℃, kuramba kwa 5% birashobora gukomeza.
Kurwanya ruswa kumiti myinshi nu mashanyarazi, byerekana inertia, aside ikomeye na alkali, amazi hamwe nudukoko twinshi kama.
Ikirere cyihanganira ubuzima busaza muri plastiki.
Amavuta menshi ni coefficente yo hasi yo guterana mubikoresho bikomeye.
Kudashyira hamwe nuburemere buke hejuru yibikoresho bikomeye, ntabwo byubahiriza ikintu icyo aricyo cyose.
Ntabwo ari uburozi hamwe nubusembwa bwa physiologique, ntabwo ari uburozi kubinyabuzima bizima.
Fluorine itondekanye valve yibanze:
Fluorine LINED VALVE IRAKWIYE KUBushyuhe bwo hejuru cyane gaze yangirika cyane hamwe namazi, ubundi bwoko bwibyuma bya pulasitiki byibyuma hamwe numuyoboro wibyuma ntibikwiye mugutanga inganda ziciriritse, ibyuma bya PTFE. Icyuma cyitwa polyvinylidene fluoride compte ikwiranye nogutanga itangazamakuru ryangirika hamwe nubushyuhe bwakazi kuva -40 ℃ kugeza + 150 ℃.
Fluorine lining valve itunganya tekinoroji
A, tetrafluoroethylene (PTFE) - uburyo bwa sodium naphthalene uburyo bwo kuvura
Polytetrafluoroethylene (PTFE) - uburyo bwo kuvura sodium naphthalene uburyo bwo guhuza uburyo bwo kuvura: sodium naphthalene yo kuvura umuti wa fluor urimo ibikoresho, cyane cyane binyuze mumazi ya ruswa yangirika hamwe na plastike ya PTFE, ukuraho igice cya atome ya fluor hejuru yibikoresho, bityo hejuru yibumoso. urwego rwa karubone hamwe nitsinda rya polar. Infrared specran yerekana ko kwinjiza itsinda rya hydroxyl, itsinda rya karubone hamwe nuburinganire butuzuye hamwe nandi matsinda ya polar hejuru, ayo matsinda arashobora kongera ingufu zubutaka, kugabanya imikoranire ya Angle, kunoza ubushuhe, kuva bigoye gukomera. Ubu ni bwo buryo bwiza kandi bukoreshwa cyane muburyo bwose bwize muri iki gihe. Sodium naphthalene tetrahydrofuran isanzwe ikoreshwa nkigisubizo cya ruswa. Inzira yo guhuza niyi ikurikira:
. igisubizo kigaragara cyijimye cyangwa umukara;
