Kodi Mitundu ya Ma Valves ndi Chiyani?: Magulu 8 ndi Ntchito Zake

Ma valve amitundu yosiyanasiyanandi zigawo zowongolera mu machitidwe operekera madzi, zomwe zimagwiritsidwa ntchito makamaka kutsegula ndi kutseka mapaipi, kuwongolera kayendedwe ka madzi, ndikuwongolera ndikuwongolera magawo a njira yoperekera madzi (monga kutentha, kuthamanga, ndi kuyenda kwa madzi).

Makamaka Mitundu 8 ya Ma Valves a msika ndi Mapaipi

Ma Vavu a Mpira

Avalavu ya mpiraali ndi kukana pang'ono kwa madzi pakati pa onsemitundu ya mavavu, ndipo ngakhale valavu ya mpira yocheperako imakhala ndi mphamvu yochepa yolimbana ndi madzi. Gawo lotsegulira ndi kutseka la valavu ya mpira ndi bwalo lokhala ndi dzenje, lomwe limazungulira mozungulira mzere wolunjika ku ngalande kuti likwaniritse cholinga chotsegula ndi kutseka ngalande.

Kotala la nthawiMa Vavu a Mpira AwiriNdi valavu yowongolera njira yodziwika bwino kwambiri. Ndi mavalavu okhala ndi njira ziwiri (yolowera ndi yotulukira), mavalavu okhala ndi malo awiri (otseguka ndi otsekedwa) omwe amagwiritsidwa ntchito kutseka kapena kulekanitsa machitidwe, ma circuits kapena zigawo mkati mwa dongosolo.

Ma Valuvu a Pulagi

Pulagi ya valavu ya valavu ya pulagi nthawi zambiri imakhala yozungulira kapena yozungulira, ndipo mawonekedwe a njirayo amatha kukhala amakona anayi kapena a trapezoidal ngati pakufunika. Vavu iyi ili ndi kapangidwe kosavuta, kosinthasintha mwachangu, kolimba pang'ono, ndipo ndi yosavuta kusintha kuti ikhale ndi njira zambiri.

Ma valve olumikizira nthawi zambiri amagwiritsidwa ntchito kudula ndi kulumikiza media, komanso kutembenuza kayendedwe ka madzi, komanso angagwiritsidwe ntchito pobowola. Popeza thupi la plug la plug limazungulira ndi tsinde la valavu kuti likwaniritse ntchito yotsegula ndi kutseka, lingagwiritsidwenso ntchito pa media yokhala ndi tinthu tomwe timapachikidwa.

Valavu ya Gulugufe

Thevalavu ya gulugufendi valavu yodziwika bwino yowongolera kuyenda kwa madzi. Mfundo yake yogwirira ntchito ndikuwongolera kuyenda kwa madzi mwa kusintha malo a gulugufe. Gulugufe akamazungulira, madziwo amasintha malo ake kudzera mu gulugufe, motero amasintha kukula kwa kuyenda kwa madziwo.

Disiki ya valavu imazungulira 90° mkati mwa mpando wa valavu kuti itsegule ndi kutseka valavu.

Valavu ya Chipata

Gawo loyamba ndi lotseka lavalavu ya chipatandiye chipata. Kayendedwe ka chipata kali kolunjika ku mbali ya madzi. Valavu ya chipata ikhoza kutsegulidwa kwathunthu ndi kutsekedwa kwathunthu, ndipo singathe kusinthidwa kapena kukanidwa.

Chipata chili ndi malo awiri otsekera. Malo awiri otsekera a valavu ya chipata yomwe imagwiritsidwa ntchito kwambiri amapanga mawonekedwe a wedge, ndipo ngodya ya wedge imasiyana malinga ndi magawo a valavu.

Valavu ya Globe

Mfundo yogwirira ntchito ya valavu yozungulira ndi kudalira mphamvu ya tsinde la valavu kuti malo otsekera diski ya valavu agwirizane bwino ndi malo otsekera mpando wa valavu kuti aletse kuyenda kwa cholumikiziracho. Vavu ikatsekedwa, mphamvu iyenera kuyikidwa pa diski kuti ikakamize malo otsekera kuti asatuluke.

Ma valve ozungulira ndi oyenera kuyatsa/kutseka komanso kugwiritsa ntchito mphamvu. Ma valve ozungulira okhala ndi njira ziwiri ndi abwino kwambiri kuti azitha kuyendetsa bwino kayendedwe ka madzi, ndipo ma valve ozungulira okhala ndi njira zitatu nthawi zambiri amagwiritsidwa ntchito kusakaniza zinthu kuchokera m'malo awiri olowera madzi ndikuwongolera chisakanizocho kudzera mu chotulutsira madzi.

Ma Vavu a Singano

Ma valve amenewa ndi ofanana kwambiri ndi ma valve ozungulira, koma ali ndi kusiyana kwakukulu kuwiri. Choyamba, ndi ang'onoang'ono, omwe amatha kuwongolera bwino kuyenda kwa madzi pamizere yaying'ono. Chachiwiri, amagwiritsa ntchito "singano" yozungulira m'malo mwa pulagi yooneka ngati diski ndi valavu ya singano yozungulira kuti azitha kuyendetsa bwino madzi.

Ma Value a Solenoid

Ma valve a Solenoid amagwira ntchito podutsa mphamvu yamagetsi kudzera mu coil, zomwe zimapangitsa coil kupanga mphamvu ya maginito, yomwe imagwira ntchito pa chitsulo kuti ipange mphamvu ya maginito, ndipo chitsulo chimasunthira ku coil, zomwe zimapangitsa kuti valavu itsegule.

Ma valve a Solenoid ndi ang'onoang'ono. Kukula kwawo kumachepetsedwa ndi mphamvu ya coil, zomwe zimachitika chifukwa cha kupindika komwe kumagwiritsidwa ntchito popanga mphamvu ya maginito ikagwiritsidwa ntchito. Kuwonjezera pa kuchepetsa mphamvu ya coil, njira yoyendera ndi malo olowera mu valavu ya solenoid nazonso ndi zazing'ono kwambiri poyerekeza ndi kukula kwa payipi.

Valavu ya Pistoni ya Angle

Valavu ya piston ya ngodya ndi mtundu wapadera wa valavu yomwe ili ndi actuator yomangidwa mkati ndipo nthawi zambiri imagawidwa ngati valavu yokhala ndi malo awiri. Actuator ikhoza kukhala yobwerera m'masika kapena yogwira ntchito kawiri, kutengera zomwe zimagwiritsidwa ntchito.

Gawo lofunika kwambiri mu valavu ndi pulagi ya valavu, yomwe imayikidwa mu njira yoyendera madzi pa ngodya inayake ndipo imakhala pampando wa valavu wopendekeka womwe umapangidwa mu njira yoyendera madzi ya valavu.

Vavu ikatsegulidwa, pulagi ya valavu imachotsedwa kwathunthu kuchokera munjira yoyendera madzi. Kapangidwe kameneka kamalola valavu ya piston ya ngodya kukhala ndi kuthamanga kwakukulu kwa madzi komanso kutsika kwa mphamvu zochepa, zomwe zimapangitsa kuti ikhale valavu yogwira ntchito mwachangu. Mu ntchito zambiri zoyatsa/kuzima, mavalavu okhala ndi ngodya ndi chisankho chotsika mtengo chomwe chingalowe m'malo mwa mavalavu achikhalidwe a mpira.

Chidule

Pali mitundu yambiri ya ma valve, ndipo kapangidwe ka ma valve kamasiyana malinga ndi mikhalidwe yosiyanasiyana yogwirira ntchito komanso zofunikira pakugwiritsa ntchito. Kuwonjezera pa ma valve 8 omwe amagwiritsidwa ntchito kwambiri omwe atchulidwa pamwambapa, palinso mitundu ina yambiri ya ma valve, monga ma valve olumikizira, ma valve oletsa kutseka, ma valve a HIPPS, ndi zina zotero.
