Nkhani - Kodi ma valve a mpira wa PVC ali ndi doko lonse?

Mukuganiza kuti valavu yanu imalola kuyenda bwino kwambiri, koma makina anu sakugwira ntchito bwino. Vavu yomwe mwasankha ikhoza kukhala ikuletsa chingwecho, ndikuchepetsa pang'onopang'ono kupanikizika ndi magwiridwe antchito osadziwa chifukwa chake.

Si ma valve onse a PVC omwe ali ndi ma doko odzaza. Ambiri ndi ma doko wamba (omwe amatchedwanso doko lochepetsedwa) kuti musunge ndalama ndi malo. Valavu yodzaza imakhala ndi dzenje lofanana ndi chitoliro kuti madzi aziyenda bwino.

Kuyerekeza mbali ndi mbali komwe kukuwonetsa kutseguka kwakukulu kwa doko lonse poyerekeza ndi valavu yokhazikika ya mpira wa port

Iyi ndi mfundo yofunika kwambiri pakupanga makina, ndipo ndi nkhani yomwe ndimakambirana nthawi zambiri ndi anzanga, kuphatikizapo gulu la Budi ku Indonesia. Kusankha pakati pa doko lonse ndi doko lokhazikika kumakhudza mwachindunji magwiridwe antchito a makina. Kwa makasitomala a Budi omwe ndi makontrakitala, kuchita izi molondola kumatanthauza kusiyana pakati pa makina ogwira ntchito bwino ndi omwe sakwaniritsa zomwe amayembekezera. Pomvetsetsa kusiyana kumeneku, amatha kusankha valavu yoyenera ya Pntek pa ntchito iliyonse, kuonetsetsa kuti makasitomala akukhutira ndikumanga mbiri yawo pantchito yabwino.

Kodi valavu ya mpira ndi valavu yodzaza ndi madoko?

Mukufunika kuyenda bwino kwambiri pamakina anu atsopano opopera. Koma mutatha kuyika, magwiridwe antchito ake ndi osasangalatsa, ndipo mukukayikira kuti pali vuto linalake, mwina kuchokera ku valavu yotseka yomwe mudagwiritsa ntchito.

Vavu ya mpira ikhoza kukhala doko lonse kapena doko lokhazikika. Bowo la valavu yotsekera yonse (dzenje) limagwirizana ndi m'mimba mwake wamkati wa payipi kuti pasakhale kuletsa kuyenda kwa madzi. Chotsekera chokhazikika chimakhala chochepa kukula kwa payipi imodzi.

Chithunzi chosonyeza kuyenda kosalala, kopanda malire kudzera mu valavu yonse ya port poyerekeza ndi kuyenda kocheperako mu valavu yokhazikika ya port

Teremuyo "doko lonse"(kapena chibowo chonse) ndi kapangidwe kake, osati khalidwe lapadera la ma valve onse a mpira. Kupanga kusiyana kumeneku ndikofunikira kwambiri pakusankha bwino ma valve. Valavu yonse yolumikizira yapangidwa kuti igwire bwino ntchito. Bowo mu mpira ndi lalikulu kwambiri kuti likhale lofanana ndi m'mimba mwake wa chitoliro chomwe chalumikizidwa nacho. Avalavu yokhazikika ya dokoMosiyana ndi zimenezi, ili ndi dzenje laling'ono pang'ono kuposa chitolirocho. Izi zimapangitsa kuti pakhale choletsa pang'ono.

Ndiye, kodi muyenera kugwiritsa ntchito liti chilichonse? Nayi malangizo osavuta omwe ndimapereka kwa ogwirizana nafe.

Pa ntchito zambiri za tsiku ndi tsiku, monga nthambi yopita ku sinki kapena chimbudzi, valavu yokhazikika yolumikizira madzi ndi yabwino kwambiri komanso yotsika mtengo. Koma pa waya waukulu wamadzi kapena kutulutsa kwa pampu, valavu yolumikizira madzi yonse ndi yofunika kuti mpweya ukhale wothamanga komanso woyenda bwino.

Kodi valavu ya mpira wa PVC ndi chiyani?

Mukufunika njira yosavuta komanso yodalirika yoletsera madzi. Ma valve akale a chipata amadziwika kuti amatseka kapena kudontha madzi mukamatseka, ndipo mukufunika valve yomwe imagwira ntchito nthawi zonse.

Vavu ya mpira wa PVC ndi valavu yotseka yomwe imagwiritsa ntchito mpira wozungulira wokhala ndi dzenje mkati mwake. Kutembenuza mwachangu kotala la chogwirira kumalumikiza dzenjelo ndi chitoliro kuti litsegule kapena kulitembenuza motsutsana ndi madzi kuti liletse.

Chithunzi chophulika cha valavu ya mpira wa PVC chomwe chikuwonetsa thupi, mpirawo, mipando ya PTFE, tsinde, ndi chogwirira

TheValavu ya mpira wa PVCndi yotchuka chifukwa cha kuphweka kwake kodabwitsa komanso kudalirika kwake kodabwitsa. Tiyeni tiwone mbali zake zazikulu. Imayamba ndi thupi lolimba la PVC lomwe limagwirizira chilichonse pamodzi. Mkati mwake muli mtima wa valavu: mpira wozungulira wa PVC wokhala ndi dzenje lobowoledwa bwino, kapena "bore," pakati. Mpira uwu umakhala pakati pa mphete ziwiri zotchedwa mipando, zomwe zimapangidwa kuchokera kuPTFE (chinthu chodziwika ndi dzina lake la Teflon)Mipando iyi imapanga chitseko chosalowa madzi motsutsana ndi mpirawo. Chitsinde chimalumikiza chogwirira chakunja ndi mpira wamkati. Mukatembenuza chogwirira madigiri 90, chitsindecho chimazungulira mpirawo. Malo a chogwiriracho nthawi zonse amakuuzani ngati valavu yatsegulidwa kapena yatsekedwa. Ngati chogwiriracho chili chofanana ndi chitoliro, chimakhala chotseguka. Ngati chili chopingasa, chimakhala chotsekedwa. Kapangidwe kosavuta komanso kogwira mtima aka kali ndi zigawo zochepa zosuntha, ndichifukwa chake kamagwiritsidwa ntchito m'njira zambiri padziko lonse lapansi.

Kodi pali kusiyana kotani pakati pa ma valve a L port ndi T port ball?

Pulojekiti yanu ikufuna kuti musinthe madzi, osati kungowaletsa. Mukukonzekera kulumikizana kovuta kwa mapaipi ndi ma valve, koma mukuona kuti payenera kukhala njira yosavuta komanso yothandiza kwambiri.

Chitseko cha L ndi chitseko cha T zimatanthauza mawonekedwe a bore mu valavu ya mpira ya njira zitatu. Chitseko cha L chimasuntha kayendedwe pakati pa njira ziwiri, pomwe chitseko cha T chimatha kusuntha, kusakaniza, kapena kutumiza kayendedwe molunjika.

Chithunzi chowonekera bwino chomwe chikuwonetsa njira zosiyanasiyana zoyendera madzi za valavu ya L-port ndi T-port ya njira zitatu

Tikamalankhula za madoko a L ndi T, tikupitirira ma valve osavuta kuyatsa/kutseka ndikulowa muma valve okhala ndi madoko ambiriIzi zapangidwa kuti ziziyang'anira momwe madzi akuyendera. Ndi zothandiza kwambiri ndipo zimatha kusintha ma valve angapo wamba, zomwe zimasunga malo ndi ndalama.

Ma Vavulo a Madoko a L

Valavu ya L-port ili ndi chibowo chooneka ngati "L." Ili ndi malo olowera pakati ndi malo awiri otulutsira (kapena malo awiri otulutsira ndi malo amodzi otulutsira). Chogwirira chikakhala pamalo amodzi, madzi amatuluka kuchokera pakati kupita kumanzere. Ndi kutembenuka kwa madigiri 90, madzi amatuluka kuchokera pakati kupita kumanja. Malo achitatu amatseka madzi onse. Sichingathe kulumikiza madoko onse atatu nthawi imodzi. Ntchito yake ndikungosintha.

Ma Vavulovu a T-Port

A Valavu ya T-portndi yosinthasintha kwambiri. Bore yake imapangidwa ngati "T." Imatha kuchita chilichonse chomwe L-port ingathe. Komabe, ili ndi malo owonjezera ogwirira omwe amalola kuyenda molunjika kudzera m'madoko awiri otsutsana, monga valavu wamba wa mpira. M'malo ena, imatha kulumikiza madoko onse atatu nthawi imodzi, zomwe zimapangitsa kuti ikhale yabwino kwambiri kusakaniza zakumwa ziwiri mu soketi imodzi.

T-Port	Kupatutsa kapena Kusakaniza	Inde	Kusakaniza madzi otentha ndi ozizira; kupereka njira yodutsa madzi.

Kodi ma valve a pulagi ndi odzaza ndi ma doko?

Mumawona mtundu wina wa valavu yozungulira kotala yotchedwa valavu yolumikizira. Imawoneka ngati valavu ya mpira, koma simukudziwa momwe imagwirira ntchito pankhani ya kuyenda kapena kudalirika kwa nthawi yayitali.

Monga ma valve a mpira, ma valve a pulagi amatha kukhala ndi doko lonse kapena doko lochepetsedwa. Komabe, kapangidwe kake kamapangitsa kuti zikhale zovuta kuzitembenuza komanso zimamatira pakapita nthawi kuposa valavu ya mpira.

Kuyerekeza kocheperako komwe kukuwonetsa momwe valve yolumikizirana ndi valve ya mpira imagwirira ntchito

Iyi ndi kufananiza kosangalatsa chifukwa kukuwonetsa chifukwa chakemavavu a mpiraakhala amphamvu kwambiri mumakampani. Avalavu yolumikiziraimagwiritsa ntchito pulagi yozungulira kapena yopapatiza yokhala ndi dzenje mkati mwake. Valavu ya mpira imagwiritsa ntchito mpira. Zonsezi zitha kupangidwa ndi khomo lonse lotseguka, kotero pankhani imeneyi, ndizofanana. Kusiyana kwakukulu kuli momwe zimagwirira ntchito. Pulavu ya valavu ya pulagi ili ndi malo akuluakulu kwambiri omwe amalumikizana nthawi zonse ndi thupi la valavu kapena cholumikizira. Izi zimapangitsa kukangana kwambiri, zomwe zikutanthauza kuti imafuna mphamvu zambiri (torque) kuti izungulire. Kukangana kwakukulu kumeneku kumapangitsanso kuti ikhale yosavuta kugwira ngati sikugwiritsidwa ntchito nthawi zonse. Valavu ya mpira, kumbali ina, imatseka ndi mipando yaying'ono ya PTFE, yolunjika. Malo olumikizirana ndi ochepa kwambiri, zomwe zimapangitsa kuti kukangana kuchepe komanso kugwira ntchito bwino. Ku Pntek, timayang'ana kwambiri kapangidwe ka valavu ya mpira chifukwa imapereka kutseka kwabwino kwambiri popanda khama lalikulu komanso kudalirika kwa nthawi yayitali.

Mapeto

Si ma valve onse a mpira wa PVC omwe ali ndi ma doko odzaza. Nthawi zonse sankhani ma doko odzaza a machitidwe othamanga kwambiri komanso ma doko wamba kuti mutseke kuti muwongolere magwiridwe antchito ndi mtengo wake malinga ndi zosowa zanu.
