Ubuyobozi bw'Intebe y'Umupira w'Amasasu: Imikorere, Ibikoresho (Intebe ya PTFE n'ibindi) n'Ubushyuhe bw'Ingano | Ultimate Seal
Mu isi yavalve z'umupira, gufunga neza ni ingenzi cyane. Ishingiro ry'iyi nshingano y'ingenzi ni igice cy'ingenzi:Intebe y'umupira w'agatebo, akenshi yitwa gusaIntebe ya ValveIyi ntwari itazwi cyane ni yo "ntwali ikomeye" y'itsinda rya Ball Valve.
Intebe y'umupira w'agatebo ni iki?
ItsindaIntebe y'umupira w'agateboni ikintu cy'ingenzi cyo gufunga murivalve y'umupiraimiterere. Ubusanzwe ikozwe mu byuma cyangwa ibikoresho bitari iby'icyuma, ishyirwa imbere mu gice cy'umubiri w'imvange. Inshingano yayo y'ibanze ni ugukora uburyo bwo gufunga neza hamwe n'umupira uzenguruka. Mu gukomeza gukorana neza,Intebe ya Valveituma valve ifunga neza cyangwa ikagenzura urujya n'uruza rw'amazi.
Akaga Gatatu k'Intebe ya Valve: Birenze Ikimenyetso Gusa
IgezwehoIntebe z'umupira w'agatebobifite ubushobozi butangaje burenze gufunga by'ibanze:
1. Gufunga bihindagurika (Ishusho-Shifter):Kimwe n'umusego w'ifuro ry'inyuma ujyanye n'umutwe wawe, Intebe y'ingufu nziza ikomeza ubushyuhe mu gihe cy'ubushyuhe bukabije (reba ibipimo bya ASTM D1710, ubusanzwe -196°C kugeza +260°C). Ubu bushyuhe butuma ibasha kwishyura ubwangirike buke ku buso bw'umupira, bigatuma ikomeza gufunga neza igihe kirekire.
2. Umuyobozi w'amazi (Umurinzi):Imiterere yihariye, nka V-port Ball Valve Seats, iyobora neza icyuma gitemba. Uku gutemba kw'amazi ku buryo bugororotse bifasha gushakisha ahantu hafunga, bikarinda kwirundanya kw'imyanda cyangwa uduce duto dushobora kwangiza icyuma gifunga.
3. Ushinzwe ubutabazi bwihutirwa (Umutekano w'inkongi y'umuriro):Imiterere imwe n'imwe y'intebe ya Valve ikubiyemo ibintu birinda inkongi. Mu gihe habaye ubushyuhe bukabije (nk'umuriro), iyi ntebe ikozwe kugira ngo ihindure karubone cyangwa ihindure karubone. Iyi nyunganiramirire ya karubone ikora ikimenyetso cya kabiri, cyihutirwa kuva ku cyuma kugera ku cyuma, bikarinda kwangirika gukabije.
Ubumenyi bwo Gufunga: Uko Intebe y'Abasharafu Ikora
Gufunga bibaho binyuze mu gukandagira mu buryo butaziguye. Iyo umupira uzunguruka ugana mu mwanya ufunze, ukandagira cyane kuIntebe y'umupira w'agatebo. Uyu muvuduko uhindura gato intebe y'intebe, bigatuma habaho uruzitiro rudasohoka neza ku gice cy'imbere. Amavali asanzwe y'umupira akoresha intebe ebyiri za Valve - imwe iri ku ruhande rw'aho yinjira n'indi iri ku ruhande rw'aho asohokera. Iyo ifunze, izi ntebe "zipfuka" umupira neza, zishobora kwihanganira umuvuduko ugera kuri 16MPa (kuriIbipimo ngenderwaho bya API 6D). Imiterere myiza, nk'intebe za V-port, ishobora kunoza cyane uburyo bwo kuzifunga binyuze mu mbaraga zo gukata zigenzurwa zikora ku byuma bikoresha ibyuma.
Ingano y'ubushyuhe bw'intebe ya Valve y'umupira: Ibintu by'ingenzi
Imipaka y'ubushyuhe bw'imikorere yaIntebe y'umupira w'agateboahanini bigenwa n'imiterere y'ibikoresho byayo. Dore isesengura ry'ibikoresho bisanzwe byo kwicaraho n'ubushyuhe bwabyo:
Intebe z'umupira w'agapira koroshye (zishingiye kuri polymer na elastomer):
•Intebe ya PTFE (Polytetrafluoroethylene):Amahitamo asanzwe. Intebe za PTFE ni nziza mu kurwanya ingese kandi zikora neza hagati-25°C kugeza +150°CKu bijyanye n'ibikoresho bikomeye bisaba gutwara igare kenshi, PTFE ikozwe nezaIntebe (zigera ku buremere bwa ± 0.01mm) zifatanye n'imipira ikozwe mu buryo bwihariye zishobora gutanga imizunguko irenga 100.000 nta gusohoka - zujuje ibipimo bya ISO 5208 Class VI.
• PCTFE (Polychlorotrifluoroethylene):Ni byiza kuri serivisi zikoreshwa mu gukwirakwiza amazi. Ikora neza uhereye ku-196°C kugeza +100°C.
• RPTFE (PTFE yongerewe imbaraga):Yongerewe imbaraga kugira ngo irambe kandi igire ubushyuhe bwinshi. Ikwiriye:-25°C kugeza +195°C, ni nziza cyane ku bikoresho bikoreshwa mu buryo bworoshye.
• PPL (Polyfenilene):Ikora neza cyane mu gushyushya. Koresha imbere-25°C kugeza +180°C.
• Viton® (FKM Fluoroelastomer):Izwiho kurwanya imiti n'ubushyuhe bwinshi (-18°C kugeza +150°CKoresha witonze hamwe n'umwuka/amazi.
• Silikoni (VMQ):Itanga ubushobozi bwo kugera ku bushyuhe bwinshi kandi idafite imiti ihagije (-100°C kugeza +300°C), akenshi bisaba ko umuntu akira nyuma yo kuvurwa kugira ngo agire imbaraga zihagije.
• Buna-N (Nitrile Rubber - NBR):Uburyo bworoshye kandi buhendutse bwo gukoresha amazi, amavuta n'ibicanwa (-18°C kugeza +100°C). Ubudahangarwa bwiza bwo kwangirika.
• EPDM (Ethylene Propylene Diene Monomer):Ni nziza cyane mu kurwanya ozone, imihindagurikire y'ikirere, no gukoresha HVAC (-28°C kugeza +120°CIrinde ibikomoka kuri hydrocarbon.
• MOC / MOG (Ibikoresho bya PTFE byuzuye karubone):Bitanga ubushobozi bwo gutuza no kudashira. MOC/MOG isanzwe iratandukanye.-15°C kugeza +195°C.
• MOM (PTFE yuzuye karubone yahinduwe):Yagenewe kwangirika, ikoreshwa mu buryo butandukanye-15°C kugeza +150°C.
• PA6 / PA66 (Nylon):Ni nziza ku gitutu no kwangirika (-25°C kugeza +65°C).
• POM (Asetali):Ingufu nyinshi n'ubukana (-45°C kugeza +110°C).
• PEEK (Polyetheretherketone):Polima nziza cyane. Ubushyuhe budasanzwe (-50°C kugeza +260°C), igitutu, kwangirika, no kudakoresha imiti. Irwanya cyane hydrolysis (amazi ashyushye/umwuka).
Intebe z'umupira w'agatebo gakomeye (zishingiye ku byuma n'amasukari):
• Ibyuma bitagira umuze + Tungsten Carbide:Umuti ukomeye ku bushyuhe bwinshi (-40°C kugeza +450°C).
• Amavuta akomeye (urugero, Icyogajuru) + Ni55 / Ni60:Kwangirika cyane no kudashyuha cyane (-40°C kugeza +540°C).
• Aloyi y'ubushyuhe bwinshi (urugero, Inconel, Hastelloy) + STL:Yakozwe mu rwego rwo gutanga serivisi zikomeye cyane (-40°C kugeza +800°C).
Igitekerezo cy'ingenzi:Ibikoresho byavuzwe haruguru bigaragaza amahitamo asanzwe.Intebe y'umupira w'agateboguhitamo bigomba gushingira kuimiterere yihariye y'imikorere(ubushyuhe, umuvuduko, ubushyuhe buciriritse, inshuro z'uruziga, nibindi) bya buri gikorwa. Hari ibindi bikoresho byinshi byihariye bihari kugira ngo byuzuze ibisabwa bidasanzwe uretse ubushyuhe gusa. Buri gihe gisha inama abakora valve kugira ngo baguhe inama zijyanye n'ibikoresho byawe. UburenganziraIntebe ya Valveni ingenzi kurivalve y'umupiraimikorere n'igihe kirekire.
