Valavu ndi cholumikizira cha mapaipi omwe amagwiritsidwa ntchito ndikutseka mapaipi, kuwongolera mayendedwe, kuwongolera ndikuwongolera magawo (kutentha, kupanikizika ndi kuchuluka kwa sing'anga. Malinga ndi ntchito yake, imatha kugawidwa m'mavesi otsekeka,Chongani Mavalve, mavesi owongolera, etc.
Ma Valves ndi zigawo zowongolera m'mayendedwe amadzimadzi, omwe ali ndi ntchito zotsekemera, malamulo, kusokonekera, kupewa kupsinjika, kusinthasintha, kupumula kapena kusintha kwamphamvu. Mavavu oyendetsa madzi oyendetsa madzi osiyanasiyana kuchokera ku mavavu osavuta kwambiri ku zigwa zovuta kwambiri zomwe amagwiritsa ntchito mu makina owongolera okha.
Ma Valves angagwiritsidwe ntchito kuwongolera mayendedwe osiyanasiyana amtundu wa mpweya monga mpweya, madzi, nthunzi, ma media, ma cerels a radio ndi matchulidwe ojambula. Malinga ndi zomwe zili, mavavuwo amagawidwansokuponyera ma val, Dnyezani maagwaleti, mavuvu achitsulo osapanga dzimbiri (201, 304, 316, 316, ndi Sremet.)
Ila m'mulu lake
Pogwira ntchito ndi kugwiritsa ntchito
(1) valavu
Valavu iyi imagwiritsidwa ntchito potseguka ndikutseka. Imakhazikitsidwa kotheratu mkati ndi kutulutsa kwa ozizira ndi kutentha, kulowa ndi zida, ndi nthambi ya mapaipimu (kuphatikizapo vumbale yamphamvu ya mpweya. Ma Valani Matambo Otsekemera AmaphatikizidwaMavesi pachipata, ma valves a Globha, mavesi a mpira ndi mavalo ankhondo.
Mavesi pachipataItha kugawidwa mu ndodo yotseguka ndi ndodo yamdima, RAM imodzi ndi Ram Ram, REDELL RAM ndi Phiri la Chipata sichabwino, ndipo nkovuta kutsegula chikho cha pachipata chachikulu; Kukula kwa thupi la Valavu ndi kochepa komwe kumayenda pamadzi oyenda m'madzi, kukana kochepa kumakhala kochepa, ndipo mawonekedwe a nomwelis alvel valavu ndi yayikulu.
Malinga ndi kuwongolera komwe sing'anga, valavu ya dziko lapansi yagawidwa m'mitundu itatu: Kudutsa molunjika, mtundu wa tsitsi lolowera, ndipo pali ndodo zotseguka komanso ndodo zakuda. Mphamvu yakutseka ya dziko lapansi ndiyabwino kuposa ya valavu ya pachipata, thupi litakhala lalitali, lotuluka limakhala lalikulu, ndipo mulifupi kwambiri ndi DN200.
Nphweya ya valavu ya mpira ndi mpira wotseguka. Mbande yogwira ntchito yogwira ntchito imapangitsa kuti mpira utseguke pomwe ukuyang'anizana ndi mapisi am'kati, ndipo amatsekedwa bwino pomwe amatembenuka 90 °. Valve Valve ili ndi kusintha kwina ndikutseka mwamphamvu.
Spool yaGulugufe wa Gulugufendi disc yozungulira yomwe imazungulira mozungulira shaft ya chitoliro chokhazikika. Pomwe ndege ya valavu imakhala yogwirizana ndi axis ya chitoliro, iyo imatsegulidwa kwathunthu; Pamene ram ndege ndi yokhazikika ku nkhwangwa ya chitoliro, imatsekeka bwino. Kutalika kwa gulugufe kutalika kwa thupi ndi kochepa, kutuluka kwake kumakhala kochepa, ndipo mtengo wake ndi wokulirapo woposa wa chipata ndi ma valves padzikoli.
(2) Chongani valavu
Valavu iyi imagwiritsidwa ntchito popewa kubwerera kwa sing'anga, ndikugwiritsa ntchito mphamvu zam'madzi za kinetic kuti mutsegule zokha ndikutseka zokha zikamayenda mbali ina. Kuyimirira pa pulati, kutumphuka kwa msampha, ndi malo ena kumene kutuluka kwa madzimadzi sikuloledwa. Pali mitundu itatu ya mavesi: mtundu wotseguka kuzungulira, kukweza mtundu ndi mawonekedwe. Pankhani ya Swing Check Mavalve, madziwo amatha kutuluka kuchokera kumanzere kupita kumanja ndikutseka zokhazokha pomwe imayenda mbali ina. Pazitsulo zokweza, spoul imakweza kuti apange njira ngati madzimadzi amatuluka kupita kumanzere, ndipo spool imatsekedwa pomwe imasinthidwa pampando pomwe kutuluka kumabwezeretsedwa. Pa valavu yoyang'ana bwino, pomwe madzi amatuluka kuchokera kumanzere kupita kumanja, valavu yotseguka imatsegulidwa kuti apange njira, ndipo valavu ya valavu imakanikizidwa kumpando wa Valasi ndikutseka pomwe njira yosinthira imasinthidwa.
(3) Kuwongoleramavuvu
Kusiyanitsa pakati pa valve ndi kumbuyo kwa valavu ndi kotsimikizika kwamphamvu, ndipo ikafika yochepa, ndipo ikafika povuta kwambiri. Valve Valve imatha kusintha stroul strooke kuti isinthe kukana kwa valavu ya valavu malinga ndi chitsogozo ndi kukula kwa chizindikirocho, kuti mukwaniritse cholinga chotsatira Valave. Mavvu oletsa kuwongolera amagawidwa ndi mavalidwe am'manja ndi ma valve okha, ndipo pali mitundu yambiri ya kalembedwe kapena mavesi okhaokha, ndipo kusintha kwawo kuli kosiyananso. Ma Valve Overtive Autot amaphatikizanso mavesi oyendetsa okha ndikudzipangitsa okha kukhala odziyimira pawokha.
(4) Voucuum
Vuluum akuphatikizanso ma valsuum a mpira, vacuum diaffle, mavavuni okhala ndi mavatumbo, etc.
(5) Magulu apadera apadera
Zolinga zapadera zimaphatikizapo ma valves a nkhumba, ma valves, mavalvesdownwon, mavuvu otha, zosefera, etc.
Valavu yotulutsa ndi chinthu chofunikira kwambiri mu dongosolo la mapaipi, lomwe limagwiritsidwa ntchito kwambiri mu boalers, zowongolera mpweya, mafuta ndi mpweya, zopezeka madzi ndi ma pichelines. Nthawi zambiri imayikidwa pamalo opondera kapena chizolowezi chochotsera mpweya wowonjezera mu bomba, kusintha luso la kugwiritsidwa ntchito kwa mapaipi ndikuchepetsa kugwiritsa ntchito mphamvu.
Mphira uliwonse wokhala pansiGulugufe wa Gulugufe, chipata cha pachipata, y-stone, valavu yokhotakhota,Wambiri wapamwamba kwambiriMafunso, mutha kulumikizana nawoMasewera a TVfakitale. Komanso mutha kudina Tsamba lathu la webusayiti ya HTTS:
