Valavu ya Gulugufe Yozungulira Yokhala ndi Mphira
✧ Kufotokozera
Vavu ya gulugufe yozungulira yokhala ndi kapangidwe kokhala ndi rabala ndi mtundu wa valavu yamafakitale yomwe imagwiritsidwa ntchito kwambiri powongolera kapena kusiyanitsa kuyenda kwa madzi m'mapaipi. Nayi chidule chachidule cha mawonekedwe ndi mawonekedwe ofunikira a valavu yamtunduwu: Kapangidwe kozungulira: Mu valavu ya gulugufe yozungulira, pakati pa tsinde ndi pakati pa diski zimayikidwa molunjika, ndikupanga mawonekedwe ozungulira ozungulira pamene valavu yatsekedwa. Kapangidwe kameneka kamalola njira yoyenda bwino komanso kutsika pang'ono kwa mphamvu kudutsa valavu. Vavu ya Gulugufe: Vavu imagwiritsa ntchito diski, kapena "gulugufe," yomwe imalumikizidwa ku tsinde lapakati. Vavu ikatsegulidwa kwathunthu, diski imayikidwa molingana ndi njira yoyendera, kulola kuyenda kosalephereka. Vavu ikatsekedwa, diski imazunguliridwa molunjika ndi kuyenda, ndikuletsa kuyenda bwino. Yokhala ndi Rabala: Vavu ili ndi mpando wa rabala, womwe umagwira ntchito ngati chinthu chotseka pakati pa diski ndi thupi la valavu. Mpando wa rabara umathandiza kuti valavu izimitse bwino ikatsekedwa, zomwe zimathandiza kuti madzi azituluka komanso kuti ikhale yolimba ngati thovu. Ntchito Zoyenera: Mtundu uwu wa valavu nthawi zambiri umagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo madzi ndi madzi otayira, machitidwe a HVAC, kukonza mankhwala, mafuta ndi gasi, kupanga magetsi, ndi ntchito zamafakitale. Kugwiritsa Ntchito: Mavalavu a gulugufe ozungulira amatha kugwiritsidwa ntchito pamanja pogwiritsa ntchito chowongolera chamanja kapena chowongolera giya, kapena amatha kuyendetsedwa ndi magetsi kapena ma actuator a pneumatic kuti agwire ntchito patali kapena yokha. Mukasankha valavu ya gulugufe yozungulira yokhala ndi kapangidwe ka rabara, zinthu monga kukula kwa valavu, kuchuluka kwa kuthamanga kwa mpweya, kutentha, mawonekedwe a madzi, ndi kugwirizana kwa zinthu ndi zolumikizira zomwe zikuyendetsedwa ziyenera kuganiziridwa mosamala.
✧ Zinthu Zofunika pa Valve ya Gulugufe Yozungulira
1. yaying'ono komanso yopepuka, yosavuta kusokoneza ndi kukonza, ndipo ikhoza kuyikidwa pamalo aliwonse.
2. Kapangidwe kosavuta, kakang'ono, mphamvu yaying'ono yogwirira ntchito, kuzungulira kwa 90° kumatsegulidwa mwachangu.
3. makhalidwe a kayendedwe ka madzi amakhala owongoka, osinthika bwino.
4. Kulumikizana pakati pa mbale ya gulugufe ndi tsinde la valavu kumagwiritsa ntchito kapangidwe kopanda pini kuti kuthetse malo omwe angatulukire mkati.
5. Bwalo lakunja la mbale ya gulugufe limakhala ndi mawonekedwe ozungulira, zomwe zimapangitsa kuti ntchito yotseka ikhale yolimba komanso kukulitsa moyo wa valavu, komanso kusunga kutayikira konse popanda kutsekeka ndi kutsekedwa kwa mphamvu nthawi zoposa 50,000.
6. chisindikizocho chikhoza kusinthidwa, ndipo kusindikizako ndikodalirika kuti chikwaniritse kusindikiza mbali ziwiri.
7. mbale ya gulugufe ikhoza kupopedwa malinga ndi zofunikira za ogwiritsa ntchito, monga nayiloni kapena polytetrafluoroides.
8. valavu ikhoza kupangidwa kuti igwirizane ndi flange ndi kulumikizana ndi clamp.
9. njira yoyendetsera galimoto ikhoza kusankhidwa ndi manja, magetsi kapena pneumatic.
✧ Ubwino wa Valuvu ya Gulugufe Yozungulira Yokhala ndi Mphira Wokhala ndi Malo
Pakutsegula ndi kutseka valavu yachitsulo chopangidwa ndi chitsulo, chifukwa kukangana pakati pa diski ndi pamwamba pa valavu kumakhala kochepa kuposa kwa valavu ya chipata, sikutha kusweka.
Kutsekeka kapena kutseka kwa tsinde la valavu ndi kochepa, ndipo kuli ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valavu kumafanana ndi kutsekeka kwa diski ya valavu, ndikoyenera kwambiri kusintha kuchuluka kwa madzi. Chifukwa chake, valavu yamtunduwu ndi yoyenera kwambiri kudula kapena kulamulira ndi kugwedeza.

✧ Utumiki Wogulitsa Pambuyo Pogulitsa
Monga wopanga mavavu achitsulo opangidwa ndi akatswiri komanso wogulitsa kunja, tikulonjeza kupatsa makasitomala ntchito yabwino kwambiri yogulitsa pambuyo pogulitsa, kuphatikizapo izi:
1. Perekani malangizo ogwiritsira ntchito mankhwala ndi malingaliro osamalira.
2. Pa zovuta zomwe zachitika chifukwa cha mavuto a khalidwe la malonda, tikulonjeza kupereka chithandizo chaukadaulo ndi kuthetsa mavuto mkati mwa nthawi yochepa kwambiri.
3. Kupatula kuwonongeka komwe kumachitika chifukwa chogwiritsa ntchito bwino, timapereka ntchito zokonzanso ndi kusintha kwaulere.
4.Tikulonjeza kuyankha mwachangu zosowa za makasitomala panthawi ya chitsimikizo cha malonda.
5. Timapereka chithandizo chaukadaulo cha nthawi yayitali, upangiri pa intaneti ndi maphunziro. Cholinga chathu ndikupatsa makasitomala chithandizo chabwino kwambiri ndikupangitsa kuti zomwe makasitomala amakumana nazo zikhale zosangalatsa komanso zosavuta.
