Kutalisya mavalvu aadumide

Kuli misyobo myiingi alimwi amisyobo iikatazya kumvwisisisyamavalvu, ikapati kubikkilizya mavalvu aamulyango, mavalvu aa globe, mavalvu aakubelesya muya, mavalvu aabutterfly, mavalvu aapulagi, mavalvu aabbola, mavalvu aamagesi, mavalvu aa diaphragm, mavalvu aakulanga, mavalvu aakwabilila, mavalvu aakucesya muya, mavalvu aakujala busi alimwi amavalvu aakujala muchiindi cheenzu, azimwi, eezyo zibelesyegwa kapati, mavalvu aamulyango, mavalvu, pesi mavalvu aapulaji vvalavu, vvalavu yabbola, vvalavu yakulanga, vvalavu ya diaphragm.

1 Valve ya Butterfly
Ivalvu yabutterfly ninzila yakujula akujala ya butterfly plate ilakonzya kuchitwa akuzinguluka 90° kuzyunguluka ntalisyo iitazungaani mumubili wa valve. Ivalvu ya Butterfly niini mubupati, njiini mubulemu alimwi njiubauba mubupange, mpo ilijisi buyo zibeela ziche. Alimwi chiyanda buyo kuzungaana 90°; ilakonzya kujalulwa akujalwa chakufwambaana, mpawo kuchita nchuubauba. Eelyo vvalavu yabutterfly noili muchiimo chijalukide, bupati bwabbatterfly plate mbobukonzya kukasya aawo akati-kati nikwiinda mumubili wavalvu, aboobo kudonkola kwanguzu kuchitwa avalvu nkusyoonto loko, aboobo ilijisi bube bwakweendelezya kweenda kabotu. Ivalvu ya Butterfly ilaandaanizyidwe muzibeela zya elastic soft seal antoomwe a metal hard seal. Ivalvu yakujala iijisi nguzu, nkomo yakujala ilakonzya kubikwa amubili wa valve naakuti kujatikizyidwe kumbali aadisiki, akubeleka kabotu kwakujala, ooko kukonzya kubelesegwa kukwabilila, mapaipi aamuwo aakati-akati alimwi azintu zikonzya kubola. Mavalvu ajisi zijazyo zyabutale kanjikanji alapona kwachiindi chilamfu kwiinda aayo ajisi zijazyo zya elastic, asi nkuyumu kujala koonse. Kanji-kanji zibelesyegwa muziindi zyakusanduka kupati kwakuzuza akuseluka kwanguzu mpawo ziyandika kuchita obotu. Zijazyo zyabutale zilakonzya kuzyibila kupya kapati, kakuli zijazyo zya elastic zilakonzya kulesyegwa akupya.

2Ivalvu yamulyango
Ivalavu lyamulyango lyaamba vvalavu eelyo mubili walyo uujula akujala (puleti lyavalvu) ndyokweendelezyegwa achisamu chavalvu mpawo lilaunka kuya mujulu akuseluka aawo mpaajala chibbula, eecho chikonzya kuswaanganya naa kugonka nzila yamaanzi. Kweezyanisya a globe valve, gate valve ilijisi mulimo mubotu wakujala, tiikwe nguzu zyakukazya maanzi, tiikwe nguzu zyakujalula akujala, alimwi ilijisi nguzu zyakubambulula. Njimwi yamavwili aabelesyegwa kapati. Bubi mbwakuti bupati mbupati, bupange bulikatazyi kwiinda bwa globe valve, busena bwakujala bulaubauba kusama, alimwi tabuli buuba kubamba. Kanjaanji, tachikonzyi kubelesegwa throttle. Kweelana aawo mpoibede ntambo aamulyango wamulyango, ilaandaanizyigwa muzibeela zyobile: musyobo wamusako uujalukide amusyobo wamusamu uusiya. Kweelana abupange bwamulyango, ulakonzya kwaandaanizyigwa muzibeela zyobile: musyobo wa wedge a parallel type.

3 Valve yakulanga
Ivalvu yakukwabilila ni valve iikonzya kulesya kujokela kwamaanzi. Chivwunisyo cha valve ya check valve chijalulwa aansi aanguzu zyamaanzi, mpawo maanzi azwa kulubazu lwakunjila kuya kulubazu lwakuzwa. Aawo muya uuzwa kulubazu lwakunjila nuuli munsi kwiinda uuzwa kulubazu lwakuzwa, chivwunisyo cha valve chiyoojala biyo akaambo kakusiyana kwanguzu zyamaanzi, nguzu zyakwe zyakukwela zintu azintu zimwi kutegwa maanzi atajoki musule. Kweelana abupange, ilakonzya kwaandaanizyigwa kuba vvalavu yakunyamuna a vvalavu yakulanga. Musyobo wakunyamuna ulaa mulimo mubotu wakujala akukwabilila maanzi kwiinda musyobo wakuzungaanya. Kubusena bwakuyoya bwapayipi lyakuyoya lyapompi, vvalavu lyaansi lyeelede kusalwa. Mulimu wayo ngwakuzuzya mupaipi wakunjilila mupompi amaanzi katanatalisya pompi; bamba payipi yakunjilila amubili wa pompi kazizwide maanzi pompi niyaimikwa, kuchitila kuti ubambile kutalika alimwi. Ivalvu yamunsi kanjikanji ibikkwa buyo aamupayipi uuimvwi wa pompi, mpawo akati-kati ulazwa ansi kuya atala.

4 Globe valve
Ivalvu ya globe ni valve iijalidwe kuya ansi, mpawo chibeela chakujalula akujala (valve) chisololelwa achisiko cha valve kuti chiunke kuya mujulu akuseluka kweendelana a axis ya valve seat (busena bwakujala). Kweezyanisya a gate valve, ilijisi mulimo mubotu wakubambulula, ilakonzya kujala kutali kabotu, bupange buuba, kupanga akubamba kabotu, ilakonzya kukazya maanzi manji alimwi amuulo musyoonto.

5 bbola lyavalvu
Bbazu lyakujula akujala lya bbola lya valvu nchintu chijisi mpako iizungulukide, mpawo bbola lilazungaana achisiko cha valve kuchitila kuti valve ijaluke akujalwa. Ibbola lya bbola lilijisi bupange buuba, lilafwambaana kuchincha, lilabeleka kabotu, lilaa bupati buniini, lilaanguzu, zibeela zisyoonto, lilakonzya kukazyigwa amaanzi masyoonto, lilakonzya kujala kabotu alimwi lilakonzya kubamba kabotu.

6 Ivalavu ya throttle
Bupange bwa throttle valve bulikozyene a globe valve kunze lya valve disc. Ivalvu disiki nchintu chikwabilila muya, mpawo ziimo zisiyene zilijisi bube bwiindene. Bulamfu bwachuuno cha valve tabuyelede kuba bupati pe, nkaambo bulamfu bwakujalula mbuniini. Mweelwe waakati-akati wakuzuza ulatanta, aboobo ulafwambaanya kubola kwa valve disc. I throttle valve ilijisi bupati buniini, njumu alimwi ilakonzya kuchita obotu, pesi kuchita obotu takuli kabotu pe.

7 Pulagi vvalavu
Ipulagi ibelesya mubili wapulagi uulaa mpako mbuli cibeela chakujalula akujala, mpawo mubili wapulagi ulazungaana achisiko cha valve kuchitila kuti vvalavu ijalulwe akujala. Ipulagi vvalavu ilijisi bubotu bwakubambwa kuuba, kuchincha chakufwambaana, kubeleka kabotu, kukazyigwa kwamaanzi masyoonto, zibeela ziche abulemu buniini. Kuli mavalvu aalulamika, aajisi nzila zyotatwe alimwi anzila zyone. Ivalvu yapulagi iinda munzila iiluleme ilabelesyegwa kutyola akati, mpawo ivalvu yapulagi iijisi nzila zyotatwe azyone ibelesyegwa kuchincha nzila yapulagi naa kwaandaanya akati.

8 Valve ya diaphragm
Cibeela chakujalula akujala cha valve ya diaphragm ni diaphragm ya raba, eeyo ili aakati ka valve achivwumbyo cha valve. Cibeela chaakati chizwa anze cha diaphragm chilijatikizyidwe achisiko cha valve, mpawo mubili wa valve ulivwumbidwe a raba. Mbwaanga chintu chili mukati tachinjili mukati kachivwumbyo chavalvu, chisiko chavalvu tachiyandiki kabbokesi kakuzuzya. Ivalavu ya diaphragm ilijisi bupange buuba, ilakonzya kujala kabotu, ilakonzya kubamba kabotu alimwi ilakonzya kukazyigwa amaanzi masyoonto. Mavalvu aa diaphragm aandaanizyigwa mumusyobo wa weir, musyobo uululamika, musyobo wa right-angle alimwi amusyobo wa direct-flow.
