Kodi valavu imagwira ntchito bwanji?

Valavu ndi cholumikizira cha paipi chomwe chimagwiritsidwa ntchito kutsegula ndi kutseka mapaipi, kuwongolera njira yoyendera, kuwongolera ndikuwongolera magawo (kutentha, kuthamanga ndi kuchuluka kwa madzi) a cholumikizira chotumizira. Malinga ndi ntchito yake, imatha kugawidwa m'ma valve otseka,ma valve owunikira, ma valve owongolera, ndi zina zotero.

Ma valve ndi zigawo zowongolera mu makina oyendera madzi, zomwe zili ndi ntchito yozimitsa, kulamulira, kusinthasintha, kupewa kubwerera kwa madzi, kukhazikika kwa kuthamanga, kusinthasintha kapena kuchepetsa kuthamanga kwa madzi. Ma valve a makina owongolera madzi amayambira pa ma valve osavuta ozimitsa mpaka ma valve ovuta kwambiri omwe amagwiritsidwa ntchito mumakina owongolera okha.

Ma valve angagwiritsidwe ntchito kuwongolera kuyenda kwa mitundu yosiyanasiyana ya madzi monga mpweya, madzi, nthunzi, zinthu zosiyanasiyana zowononga, slurry, mafuta, zitsulo zamadzimadzi ndi zinthu zotulutsa ma radioactive. Malinga ndi zinthuzo, ma valve amagawidwanso m'magulu awiri:mavavu achitsulo choponyedwa, ma valve achitsulo chopangidwa ndi chitsulo, ma valve achitsulo chosapanga dzimbiri (201, 304, 316, ndi zina zotero), ma valve achitsulo a chrome-molybdenum, ma valve achitsulo a chromium-molybdenum vanadium, ma valve achitsulo cha duplex, ma valve apulasitiki, ma valve osakhala achizolowezi, ndi zina zotero.

Pogwiritsa ntchito ndi ntchito

(1) Valavu yozimitsa

Mtundu uwu wa valavu umagwiritsidwa ntchito potsegula ndi kutseka. Umayikidwa kosatha m'malo olowera ndi otulutsira madzi ozizira ndi kutentha, malo olowera ndi otulutsira zida, ndi nthambi ya mapaipi (kuphatikizapo zokwezera), ndipo ungagwiritsidwenso ntchito ngati valavu yotulutsira madzi ndi valavu yotulutsira mpweya. Mavalavu odziwika bwino otseka ndi mongamavavu a chipata, ma valve a globe, ma valve a mpira ndi ma valve a gulugufe.

Ma valve a chipataZingagawidwe m'magulu awiri: ndodo yotseguka ndi ndodo yakuda, ndodo imodzi yamphongo ndi ndodo ziwiri zamphongo, ndodo ya wedge ndi ndodo yofanana, ndi zina zotero. Kulimba kwa valavu ya chipata sikwabwino, ndipo n'kovuta kutsegula valavu ya chipata chachikulu; Kukula kwa thupi la valavu ndi kochepa motsatira njira ya madzi, kukana kwa madzi ndi kochepa, ndipo kutalika kwa valavu ya chipata ndi kwakukulu.

Malinga ndi njira yoyendera ya sing'anga, valavu yozungulira imagawidwa m'mitundu itatu: mtundu wolunjika, mtundu wa ngodya yakumanja ndi mtundu wa kayendedwe kolunjika, ndipo pali ndodo zotseguka ndi ndodo zakuda. Kulimba kotseka kwa valavu yozungulira ndikwabwino kuposa kwa valavu yolowera, thupi la valavu ndi lalitali, kukana kwa kayendedwe ndi kwakukulu, ndipo mainchesi apamwamba kwambiri ndi DN200.

Chopondapo cha valavu ya mpira ndi mpira wotseguka. Chopondapo cha valavu yoyendetsedwa ndi mbale chimapangitsa mpirawo kutseguka ukakhala moyang'anizana ndi mzere wa payipi, ndipo umatsekedwa kwathunthu ukatembenuka 90°. Vavu ya mpirayo imakhala ndi magwiridwe antchito enaake osinthira ndipo imatseka bwino.

Chipolopolo chavalavu ya gulugufeNdi diski yozungulira yomwe imazungulira motsatira shaft yoyima ya axis yoyima ya chitoliro. Pamene plane ya valavu ikugwirizana ndi axis ya chitoliro, imatsegulidwa kwathunthu; Pamene ram plane ili yolunjika ku axis ya chitoliro, imatsekedwa kwathunthu. Kutalika kwa thupi la valavu ya gulugufe ndi kochepa, kukana kwa kayendedwe ka madzi ndi kochepa, ndipo mtengo wake ndi wapamwamba kuposa wa mavalavu a chipata ndi mavalavu a globe.

(2) Valavu yowunikira

Mtundu uwu wa valavu umagwiritsidwa ntchito poletsa kubwerera kwa njira yolumikizira magetsi, ndipo umagwiritsa ntchito mphamvu ya kayendedwe ka madzi kuti idzitsegule yokha ndikutseka yokha ikayenda mbali ina. Ikuyima pamalo otulukira pampu, potulukira msampha, ndi malo ena komwe kuyenda kwa madzi sikuloledwa. Pali mitundu itatu ya mavalavu owunikira: mtundu wozungulira, mtundu wokweza ndi mtundu wa clamp. Pankhani ya mavalavu owunikira ozungulira, madzi amatha kuyenda kuchokera kumanzere kupita kumanja ndipo amatseka okha akayenda mbali ina. Pa mavalavu owunikira okweza, spool imakwera mmwamba kuti ipange njira pamene madzi akuyenda kuchokera kumanzere kupita kumanja, ndipo spool imatsekedwa ikakanikizidwa pampando pamene kuyenda kwabwerera mmbuyo. Pa valavu yowunikira yolumikizira, madzi akuyenda kuchokera kumanzere kupita kumanja, pakati pa valavu imatsegulidwa kuti ipange njira, ndipo pakati pa valavu imakanikizidwa ku mpando wa valavu ndikutsekedwa pamene kuyenda kwabwerera mmbuyo.

(3) Kulamuliramavavu

Kusiyana kwa kuthamanga pakati pa kutsogolo ndi kumbuyo kwa valavu ndikotsimikizika, ndipo pamene kutseguka kwa valavu wamba kumasintha kwambiri, kuthamanga kwa madzi kumasintha pang'ono, ndipo ikafika pamalo enaake, kuthamanga kwa madzi kumasintha kwambiri, ndiko kuti, kusintha kwa madzi kumakhala koipa. Vavu yowongolera imatha kusintha kugwedezeka kwa spool kuti isinthe kukana kwa valavu malinga ndi malangizo ndi kukula kwa chizindikiro, kuti ikwaniritse cholinga chowongolera valavu yoyenda. Mavavu owongolera amagawidwa m'mavavu owongolera ndi mavavu owongolera okha, ndipo pali mitundu yambiri ya mavavu owongolera okha kapena owongolera okha, ndipo kusintha kwawo kumasiyananso. Mavavu owongolera okha amaphatikizapo mavavu owongolera madzi oyenda okha ndi mavavu owongolera kuthamanga odziyendetsa okha.

(4) Chotsukira mpweya chopanda mpweya

Vacuum imaphatikizapo ma vavu a mpira wa vacuum, ma vavu a vacuum baffle, ma vavu a vacuum inflation, ma vavu a vacuum a pneumatic, ndi zina zotero. Ntchito yake ndi mu dongosolo la vacuum, chinthu cha vacuum chomwe chimagwiritsidwa ntchito kusintha njira ya kayendedwe ka mpweya, kusintha kuchuluka kwa kayendedwe ka mpweya, kudula kapena kulumikiza payipi chimatchedwa vavu ya vacuum.

(5) Magulu a zolinga zapadera

Magulu apadera a ntchito ndi monga ma valve a nkhumba, ma valve otulutsa mpweya, ma valve otulutsa mpweya, ma valve otulutsa utsi, zosefera, ndi zina zotero.

Valavu yotulutsa utsi ndi gawo lofunikira kwambiri mu dongosolo la mapaipi, lomwe limagwiritsidwa ntchito kwambiri mu ma boiler, ma air conditioner, mafuta ndi gasi, mapaipi operekera madzi ndi otulutsira madzi. Nthawi zambiri imayikidwa pamtunda wapamwamba kapena m'chigongono kuti ichotse mpweya wochulukirapo mupaipi, kupititsa patsogolo kugwiritsa ntchito mapaipi bwino komanso kuchepetsa kugwiritsa ntchito mphamvu.

Rabala iliyonse yokhala pansivalavu ya gulugufe, valavu ya chipata, Y-stainer, valavu yolinganiza,vavu yowunikira mbale ziwirimafunso, omwe mungalumikizane nawoValavu ya TWSfakitale. Mukhozanso kudina patsamba lathu la https://www.tws-valve.com/ kuti mudziwe zambiri.
