Valve ibipimo byimbere? Valve ibikorwa byo kwirinda? Ibisobanuro byo gushushanya valve no gushiraho ikimenyetso

1, menyesha uburyo bwa valve imbere yo kumeneka nyuma yuko valve ifunze mumasaha 4-6, koresha ibipimo bya termoometero kugirango bipime uruti (hafi yumubiri wa valve) cyangwa 150mm hepfo yubushyuhe bwicyuma cyumubiri, nka hejuru ya 70 ℃, bigaragazwa nk '“kumeneka imbere”. Ubu buryo burakoreshwa mubice byinshi byimbere. Ariko mubikorwa nyirizina, twahuye nibibazo bidasanzwe bikurikira1) bitewe nuburyo bwo gushyiramo umuyoboro, hari indiba zimwe na mbere na nyuma yo guhungabana kwubushyuhe bwo hejuru, nko guhuza umuvuduko wamazi, imiyoboro ya jellyfish.
Ubwa mbere, igipimo cyo kumeneka kugipimo
1, menya uburyo bwo kumena valve
Nyuma yamasaha 4-6 yo gufunga valve, koresha ubushuhe bwa termometero kugirango upime ubushyuhe bwicyuma kuruti (hafi yumubiri) cyangwa 150mm munsi yumubiri, niba birenze 70 ° c, bifatwa nk "kumeneka imbere". Ubu buryo burakoreshwa mubice byinshi byimbere.
Ariko, mubikorwa byacu bifatika, twahuye nibibazo bidasanzwe bikurikira:
. ubushyuhe bwibiti buzaba burenze 70 ℃.
. Iyo umwanya wa valve wegereye umuyoboro mukuru, mugihe cyose icyuma cyose cyamashami mumiyoboro yatemba, ubushyuhe bwizindi mibavu buzamuka bugera kuri 70 ℃, nkibikoresho byo gutekesha ibyuka, imiyoboro y'amazi ashyushye, nibindi. Kubwibyo, GUSOBANURIRA AMAVUBI MPUZAMAHANGA MURI IYI GACIRO NAWE BIGOMBA GUKORWA NUBUNDI BURYO, NKUKO Gupima URUGERO URUGENDO RWA TEMPERATURE CYANGWA URUGENDO RWA MBERE RUGENDE RUGENDE RUGENDE RUGENDE.
Icya kabiri, imikorere ya valve ikeneye kwitabwaho
1. Ku miryango y'intoki y'amazi atemba ya sisitemu yubushyuhe, agomba kongera gukomera nyuma yisaha nigice nyuma yo kurangiza ibikorwa kugirango akureho icyuho cya valve cyatewe no kwaguka kwinshi no kugabanuka gukonje.
2. Ku muyoboro w'ubushyuhe ufite inzugi imwe cyangwa ebyiri, imikorere ya valve ikurikira: fungura umuryango rimwe mbere yo gufungura umuryango kabiri; Mugihe cyo gufunga, ugomba kubanza gufunga umuryango kabiri hanyuma ukongera gufunga umuryango.
3, kumikorere ya valve valve, irashobora gufungwa gusa cyangwa gufungura byuzuye, ntukemere ko igice cyafunguye igice gifunze leta, kugirango ugabanye ibyangiritse kuri valve.
Icya gatatu, gucunga valve ibibazo bikeneye kwitabwaho
Igice cya 1, mbere yo gutangira buri kizamini cyamashanyarazi, pneumatike yikizamini, inzira yikizamini, kigomba kuba inzobere mugukurikirana aho ibintu bigenda no kugabanuka, kugenzura imikorere ihuza inkoni na pin ntigomba kuba irekuye, yunamye kandi igwa, reba icyerekezo cyo gufungura DCS kandi mubibanza bigomba kuba bihamye, hariho intera ihagarara hagati yumuriro wamashanyarazi kugirango ugerageze guhagarara hagati nibisanzwe. Guhindura icyerekezo cyo guhindura inzugi nukuri, ibikorwa byoroshye, hamwe no guhuza ibizamini byerekeranye no guhuza umwuga wabigize umwuga, igikoresho cyo guhinduranya pneumatike kigomba kuba cyoroshye, nta kumeneka nikintu kidasanzwe, ikizamini kigomba guhagarika ikizamini mugihe kidasanzwe, kumenyesha mugihe abakozi bashinzwe kubungabunga. hamwe na.
Igice cya 2, igihe cyose utangiye bigomba kuba byujuje ibyateganijwe mubikorwa bihuye, irembo ryamazi ShuFang rigomba kugenzura ryahagaritswe naya mabwiriza, buri cyuzi cyamazi cya ShuFang kizimya (amasaha 10) nyuma yamasaha 6, nyuma y irembo ryamazi cyerekana ubushyuhe bwa hydrophobique, bigomba gushingira kumuyoboro wa valve nyuma yo gusesengura no gusuzuma niba imyanda yamenetse, ubushyuhe bwerekana ko nta bushyuhe bwerekana ko bworoshye nyuma y’amazi, Ubushyuhe bwa termoometero ikoreshwa mu gupima ubushyuhe bwurukuta rwimbere ninyuma rwa valve cyangwa wumve kugirango umenye niba valve itemba. Nk’umuriro w'amashanyarazi cyangwa pneumatike, ugomba gufungwa urugi rw'amashanyarazi rwa hydrophobique cyangwa urugi rwa pneumatike urugi rwo kwigunga, ku rugi rw'amashanyarazi rwa hydrophobique, umuryango wa pneumatike udafite urugi rwo kwigunga, nko kumeneka, ugomba kunyeganyezwa kugira ngo ufunge umuryango w'amashanyarazi, ukabura no kuvugana kuvura. Nkurugero rwintoki kumeneka, kubura no kuvura kubungabunga.
3, buri gihe mbere yuko igice gifunga, inenge ya valve (leakage) igomba kugenzurwa, valve yamenetse igomba kwinjizwa ikabimenyesha ishami rishinzwe kubungabunga.
4. Mugikorwa cyo gufungura no guhagarika cyangwa hamwe nuburyo bwo kuvoma umuvuduko, nyuma yo gufungura amarembo yamazi (gusohora), reba niba hari ubushyuhe nyuma ya valve cyangwa umwobo (umutego), kugirango urebe ko ishobora kugira uruhare rwa amazi (kurekura) amazi, kugirango wirinde kwangirika guterwa namazi yubushyuhe buterwa no guhagarika valve cyangwa umuyoboro cyangwa umwobo wa trottle (umutego).
GUSHINGA AGACIRO KANDI GUSHYIRA MU BIKORWA KUGARAGAZA KO KUMENYEKANA AGACIRO KUGARAGARA KUBONA KUBITEKEREZO BIDASANZWE N'UMUBIRI WA VALVE NA BONNET, KANDI BIKORESHEJWE MU BIKORWA BIKURIKIRA ? NK'UKO BYASOBANUWE MU mbonerahamwe hepfo. Ibara ryirangi ryuburyo bwo kohereza ryerekanwe kuburyo bukurikira: ibikoresho byamashanyarazi, ubwoko busanzwe busize irangi ryijimye; Bitatu muri kimwe (hanze, biturika-biturika, birwanya ruswa) byanditseho ikirere cyubururu; Pneumatike, hydraulic, ihererekanyabubasha hamwe nubundi buryo bwo kohereza hamwe nibara ryibicuruzwa.
1. Kumenyekanisha ibice bya valve
Kuri shell ya valve valve, hari umurongo utambitse hamwe numwambi. Imibare iri hejuru y'umurongo utambitse yerekana urwego rw'umuvuduko w'izina, kandi bimwe byerekana ubushyuhe n'ubushyuhe bwo gukora. Kurugero, PNl0 na PT510 bikoreshwa munsi yimikorere ya 10MPa na 510 ℃. Umubare uri munsi yumurongo utambitse werekana diameter nominal yumuyoboro uhuza.
→ yerekana ko valve igororotse binyuze, hagati yinjira no gusohoka yerekeza icyerekezo, mumurongo umwe cyangwa ugereranije.
Chrysene> yerekana ko igice cya valve ari ubwoko bwiburyo, buringaniye bukora igice cyo gufunga.
Yerekana ko valve ari inzira-eshatu kandi ikigereranyo gifite icyerekezo kinini.
