Mu mafayilo a mafakitale, kupewa sing'anga recfflow ndi gawo lofunikira pakuwonetsetsa kuti ndi yotetezeka. Monga chipangizo chojambulidwa bwino komanso chowoneka bwino kwambiri, valavu yamagawo awiri, yokhala ndi kapangidwe kake kake ndi ntchito zabwino, zagwiritsidwa ntchito kwambiri pamayendedwe amadzimadzi m'mafakitale ambiri.

Kapangidwe ka muyeso wa dika wapawiri makamaka kumakhala ndi thupi la valavu, valavu yama ngwazi, valavu, akasupe, mphete zopindika ndi zina. Chosiyana ndi ma valve kapena mtundu wokweza mavesi, amatengera valavu iwiri yogawika yogawika. Makina awiri awa amalumikizidwa ndi shaft valve ndikuyika mkati mwa valavu ya valavu, ndipo valavu imatha kuzungulira momasuka mozungulira shaft. Kasupe nthawi zambiri amakhazikitsidwa pakati pa valavu iwiriyi kapena kulumikizana pakati pa valavu ya valavu ya valavu imatha kutsimikiza kuti valavu imatha kutseka bwino pomwe sing'anga imasiya kuyenda kapena kutuluka m'mbuyo. Njira yoyenda ya valavu imapangidwa kuti ikhale yosalala, kotero kukana pamene sing'anga imadutsa. Kuphatikiza apo, zinthu zina zomwe zimakhudzana ndi sing'anga zimapangidwa kwambiri ndi zida zosagwiritsidwa ntchito komanso kuwonongedwa, zimaponya chitsulo, komanso chitsulo chosapanga dzimbiri ndikusintha zinthu zosiyanasiyana .

Mfundo yake yogwira ntchito imakhazikitsidwa ndi kulumikizana pakati pa kupanikizika kwapakatikati ndi mphamvu yamasika. Pamene sing'anga imayenda munjira yodziwika, sing'anga ya sing'anga imagonjetsa mphamvu ya masika, kukankhira ma ralve awiriwo kuti azungulire mozungulira valve ndi kutseguka, ndikupanga njira yosalala kuti ithetse bwino. Pakadali pano, valavu yama Valaps ali pachiwopsezo, ndipo kukana kwa madziwo ndikochepa. Pamene sing'anga imayima kapena pali chizolowezi chobwerera, mawonekedwe a sing'anga amazimiririka, ndipo mphamvu ya masika imathamangitsidwa bwino pampando wa Valatiyo, potero ndikutseka msana. Mbali yotsekera mwachangu imatha kupewa kupezeka kwa nyundo yamadzi, kupewa kuwonongeka kwa ma pichelines, mapampu ndi zida zina zomwe zimayambitsidwa ndi sing'anga .

Valavu yokhala ndi malo opezeka awiri ali ndi zabwino zambiri. Choyamba, zimayankha mwachangu. Chifukwa cha kukhazikitsidwa kwa ma vumbalo ndi makina oyambiranso, kumatha kutseka mwachangu panthawi ya sing'anga, ndipo nthawi yotseka nthawi zambiri imakhala yofupikirana ndi mavavu achikhalidwe, omwe amatha kuletsa chitetezo cha nthawi yake ndikuteteza chitetezo. Kachiwiri, kukana kwamadzi ndikochepa. Mapangidwe ake osalala oyenda ndi mawonekedwe a valavu imakola zotsatira zochepa pakapita kukakhala pang'ono pomwe, ikuluikulu imathandizira kukonza njira yoyendera mapaipi ndikuchepetsa kugwiritsa ntchito mphamvu za mapaipi. Komanso, ili ndi kapangidwe kake, voliyumu yaying'ono ndi kulemera kopepuka. Poyerekeza ndi mawonekedwe a Swing-Mtundu Wake, kulemera kwake kumatha kuchepetsedwa ndi zopitilira 30%, ndipo zofunikira zokhazikitsa ndizochepa, zomwe zimayenera makamaka ma spenarios okhala ndi malo ochepa. Kuphatikiza apo, ndikosavuta kusunga. Vutoli ndi kukonza valavu ndi yophweka, komanso yovuta kwambiri, komanso yolimba monga akasupe zojambula ndi akasupe ndizosavuta kusintha. Komanso, chifukwa cha magawo ovala ochepa, amakhala ndi moyo wautali, womwe ungachepetse ndalama zokonza komanso nthawi yopuma .

Pamapulogalamu othandiza, mavu ambiri owoneka bwino amagwiritsidwa ntchito kwambiri m'mapapu monga mafuta a petroleum, machipatala, chithandizo chamadzi, ngalande zamadzi, ndi ma metaldurgy. Pa mapaipi a pampu yamadzi, imatha kupewa kuti sing'anga kubwezeretsedwa mwadzidzidzi pomwe pampu yamadzi imayima, kupewa kuwonongeka kwa pampu yamadzi chifukwa chosinthira kusintha; Pakuyenda pazinthu zakunyumba yamankhwala, kumatha kulepheretsa njira yolumikizira media pakati pa njira zosiyanasiyana, ndikuonetsetsa kukhazikika kwa kapangidwe; Mu nthunzi ndi madzi amadzi amphuno mphamvu zomera, zimagwiritsidwa ntchito popewa kubwezeredwa kwa nthunzi kapena madzi, ndikuonetsetsa kuti agwiritse ntchito zida zofunikira monga matebire; Mu madzi akumatauni ndi njira zoyambira, imayikidwa pamapaipi am'madzi kuti mupewe kusintha madzi chifukwa cha kusinthana kwapakatikati, ndikuwonetsetsa kupitilizani ndi kukhazikika kwa madzi .

Ndi chitukuko cha ukadaulo wa mafakitale, ma dolial a mavalti awiri-dika amakonzedwa nthawi zonse. Mitundu yatsopano ya mavesi a pawiri-mbale yolumikizirana kwambiri, monga polytetrafluofenthlecleofentlene ndi rate wa nitrile, kukonza magwiridwe antchito, ndikuwonetsetsa zikhalidwe za zero ngakhale mutapanikizika kwambiri komanso kutentha kwakukulu. Nthawi yomweyo, kusintha kwapangidwa mu kapangidwe kake, monga kukhazikitsidwa kwa akasupe osinthika, komwe kumasintha mphamvu ya kasupe molingana ndi zovuta zosiyanasiyana, kotero kuti valavu imatha kukhalabe ndi boma labwino kwambiri pantchito zosiyanasiyana. Kuphatikiza apo, mavu ambiri owoneka bwino ali ndi zida zochepetsera kuti achepetse mphamvu pomaliza, amachepetsa phokoso komanso kugwedezeka, ndikuwonjezera moyo wa zida .

Kuwerenga, ndi zabwino zake zoyankha mwachangu, kukana kotsika, kapangidwe kake ka Valuw-cheke koyenera kwakhala chitsimikizo cha makina otetezeka komanso othandiza pamadzi oyenda bwino.
