Valvu y'ekihuguhugu erimu obuveera obutarikusheeshasheeshani okutaho polytetrafluoroethylene resin (nari purofayiro ekozirwe) aha kisiika ky‘omunda ky‘ebicweka by‘ekyoma nari eby‘ekyoma ebirikutwara amaani nari aha mutwe gw‘aheeru gw‘ebicweka by‘omunda by‘ebinyonyi orikukoresa omuringo gw‘okubumba (nari okutaho). Ebintu by’omutaano eby’ebikwato by’ebinyonyi ebirikurwanisa eby’okukoresa eby’amaani ebirikushiisha nibikorwa omu miringo etari emwe n’emwe y’ebikwato by’ebinyonyi n’ebintu ebirikuteera amaani.
Omu bintu ebirikurwanisa okusheenya, PTFE eine emirimo mirungi munonga etarikugyeragyeranisibwa. Oyihireho ebyoma ebishazirwe, ebiriisa bya fluorine n’ebiriisa by’omubazi, nibibaasa kukoresibwa omu miringo etari emwe n’emwe ey’amaizi g’omubiri, asidi ya sulfuric, asidi ya nitric, aqua regia, asidi y’ebihangirwe, ekirungo ky’amaani, ekirungo ky’amaani , asidi y’omubiri erikuhindukahinduka, alkali erikuhindukahinduka n’ebintu by’omubiri ebitari bimwe na bimwe nibihinduka omu muringo gw’okutooranamu. Okutaho PTFE aha kisiika ky‘omunda ky‘ekibunu ky‘ebinyonyi tikurikusingura oburemeezi bw‘amaani makye g‘ebintu bya PTFE byonka, kureka n‘okumaraho ekizibu ky‘okuzibira okusheeshasheesha kw‘ebintu by‘omutwe gw‘ekibunu ky‘ebinyonyi. Okukora kubi n’okugura ebintu bingi. Okwongyera ahari ekyo, okwiha aha kugumaho kwayo okurungi omu by’emibazi, PTFE eine emitwarize mirungi y’okurwanisa okusheenya n’okuzibira okuteerana, obucweka bukye munonga obw’amaani n’obutafaari obutarikuhinduka, n’okukora gye omu kurwanisa okuteerana n’okusiiga amajuta. Nikikozesibwa nk’ekikwato ky’okukingaho eky’okukinga n’okukinga ebishumuruzo by’ebinyonyi, kandi nikyetengyesa kukyendeeza aha rubaju rw’okukingaho. Okuteerana ahagati y’ebicupuri by’ebinyonyi nikubaasa kukyendeera, amaani g’okukora g’ebicupuri nigabaasa kukyendeera, kandi n’obwire bw’okukoresa ekintu nibubaasa kutunguuka.
Valvu y'ebinyonyi erimu fluorine, kandi emanyirwe nka anti-corrosion butterfly valve, neekira kukoresibwa omu mbeera z’okukora ezigumire, yaaba emibazi y’obutwa n’ey’akabi, nari emiringo etari emwe n’emwe ey’okusheenya munonga ey’asidi-base nari ebirungo by’ebihangwa. Okukozesa kubi nikwija kurugamu okufeerwa kw‘eby‘entaasya kwingi kandi okw‘amaani ahabw‘okugira ngu... Okukozesa gye n’okureeberera gye ekikwato ky’okukinga ebinyonyi nikibaasa kwongyera aha myaka y’okukoresa ekikwato ky’ekinyonyi ekirimu fluorine, mbwenu ni bintu ki ebirikubaasa kukorwa kukirinda gye?
1. Otakakozeise, shoma gye ebiragiro by’okukozesa valvu y’ebinyonyi erimu fluorine.
2. Kikorese omu nkora ya pressure, temperature na medium ebirikworekwa aha rupapura rw’eiziina nari omu kitabo ky’okukoresa.
3. Waaba nookozesa, zibira ekikopo ky‘ebinyonyi ekirimu fluorine kureetaho okushoberwa kwingi omu mipiira ahabw‘empindahinduka z‘obutagatsi, kikyendeeze aha mpindahinduka z‘obutagatsi, kandi oyongyereho ebikwato by‘okugaita ebiri omu muringo gwa U otakatandikire n‘enyima y‘ekikopo ky‘ebinyonyi.
4. Nikizibirwa kukoresa lever kwigura n’okukinga valve y’ebinyonyi erimu fluorine. Fayo kureeba omwanya gw‘okworeka okukingura n‘okukinga n‘ekikwato ky‘okutaho obugarukiro ky‘ekipande ky‘ebinyonyi ekirimu fluorine. Bwanyima y‘okukinga n‘okukinga biri omu mwanya, otagyema valvu kukinga, okwetantara okushiisha juba aha rubaju rw‘okukingaho oruveera rwa fluorine.
5. Aha bihandiiko ebimwe ebitarikuhamibwa kandi ebyanguhi kuvunda (nk‘eky‘okureeberaho, okuvunda kw‘ebihandiiko ebimwe nikwija kureetera okutunguuka kw‘eiraka n‘okureetera okweyongyera kwa puresha okutari kwa buriijo omu mbeera z‘okukora), ekirikuza kureetera okusiisikara kwa butterfly valve nari okusheeshasheesha, enkora ziine kukorwa kwihaho nari kukyendeeza aha nshonga ezirikureetaho okuvunda kw‘ebintu ebitarikubaasa kuvunda. . Waaba nootoorana ekikwato ky‘okukyebera, ekikwato ky‘okukyebera ekirimu fluorine ekirimu ekikwato ky‘okukyendeeza aha nkora y‘okwekorera kiine kutooranwa orikuteekateeka aha mpindahinduka ezirikubaasa kubaho omu mbeera z‘okukora ezirikureetwaho okuvunda okutagumire kandi okwanguhi kw‘ekintu ekiri ahagati.
6. Ahabwavalvu y'ebinyonyi erimu fluorineaha payipu erimu obutwa, oburikwotsya, oburikuturika kandi oburikusheeshasheesha obw’amaani, nikizibirwa munonga kugaruraho ekipapura ahansi y’okugyemeserezibwa. N‘obu valve y‘ebinyonyi erimu fluorine eraabe eine omurimo gw‘okukingaho ogw‘ahaiguru omu kuteekateeka, tikirikubaasika kuhindura okupakira ahansi y‘okugyemeserezibwa.
7. Aha mipiira erimu ebiriisa ebirikwotsya, enkora ziine kukorwa kureeba ngu obutagatsi bw’omumwanya n’obutagatsi bw’embeera y’okukora tiburikubaasa kurenga aha nshonga y’okwotsya ebirikwetunguura eby’ekintu okuzibira akabi akarikureetwaho omushana gw’eizooba nari omuriro gw’aheeru.
Omuringo ogurikukoresibwa: ebicweka bitari bimwe na bimwe eby‘omunyugunyu gwa asidi-base n‘ebimwe aha bihingwa ebirikukora.
