"Momwe Mungasankhire Valve ya Globe Molondola: Chitsogozo cha Mitundu ndi Zochitika Zogwiritsa Ntchito"
1,Mwachidule
Valavu ya Globe ndi mtundu womwe umagwiritsidwa ntchito kwambiri, womwe umagwiritsidwa ntchito kwambiri podula madzi m'mapaipi. Kusankha koyenera kwa ma valve otseka ndi chinsinsi chowonetsetsa kuti mapaipi akuyenda bwino. Bukuli likuwonetsani momwe mungasankhire bwino valve yotseka, kuphatikiza mtundu wake ndi mawonekedwe ake.
2,Mtundu wa valve yotseka
1. Zosankhidwa ndi ma valve:
a) Kuwongoka kupyola valavu yapadziko lonse: Njira yamadzimadzi imadutsa molunjika, yokhala ndi mawonekedwe osavuta komanso osasunthika, kupangitsa kuti igwiritsidwe ntchito kwambiri.
b) Valovu ya globe: Njira yamadzimadzi ili pamtunda wa digirii 90, imatenga malo ang'onoang'ono komanso oyenera malo okhala ndi malo ochepa.
c) Valavu yapadziko lonse lapansi yolunjika: Njira yamadzimadzi imakhala yowongoka ndipo imakhala ndi kukana kothamanga kwambiri, ndikupangitsa kuti ikhale yoyenera pamikhalidwe yotsika komanso yotseka.
2. Zosankhidwa ndi ma valve:
a) Carbon steel globe valve: yoyenera kugwiritsidwa ntchito m'mafakitale ndi media monga madzi, mafuta, nthunzi, etc.
b) Valavu yachitsulo chosapanga dzimbiri: yoyenera malo okhala ndi ukhondo wambiri, monga zamadzimadzi zowononga, mpweya, mankhwala, ndi zina.
c) Fluorine valavu yapadziko lonse lapansi: yoyenera malo okhala ndi mankhwala owononga, ma acid amphamvu, ma alkali amphamvu, ndi media zina.
3. Amasankhidwa poyendetsa galimoto:
a) Valavu yotseka pamanja: Yang'anirani kutsegulira ndi kutseka kwa valve pozungulira pamanja tsinde la valve, losavuta komanso losavuta kugwiritsa ntchito, loyenera kupanikizika pang'ono ndi ntchito zazing'ono.
b) Valavu yamagetsi yamagetsi: Kuwongolera zokha kumatheka poyendetsa tsinde la valavu kuti lizizungulira kudzera mugalimoto yamagetsi, yoyenera kupanikizika kwapakatikati ndi kumtunda, ntchito zazikulu zamkati.
c) Valavu ya pneumatic globe: Imayendetsedwa ndi kuthamanga kwa mpweya kutembenuza tsinde la valavu, kukwaniritsa kulamulira kwadzidzidzi, koyenera kwapakati ndi kupanikizika kwakukulu, zochitika zazikulu zapakati.
3,Mawonekedwe ogwiritsira ntchito ma valve a globe
1. Njira yoperekera madzi: imagwiritsidwa ntchito kudula magwero a madzi, kukwaniritsa kuyambitsa, kutseka, ndi kukonza.
2. Makampani a petrochemical: amagwiritsidwa ntchito kuthetsa zofalitsa zosiyanasiyana, monga mafuta, gasi, madzi, ndi zina zotero, kuti atsimikizire chitetezo chopanga.
3. Makampani opanga magetsi otenthetsera: amagwiritsidwa ntchito kudula zofalitsa monga madzi otentha ndi nthunzi, kuonetsetsa kuti ma boilers ndi zida zotenthetsera zikuyenda bwino.
4. Makampani opanga zakudya ndi zakumwa: amagwiritsidwa ntchito podula zofalitsa monga chakudya ndi zakumwa, kuonetsetsa ukhondo wa chilengedwe.
5. Makampani opanga mankhwala: amagwiritsidwa ntchito podula zopangira mankhwala, mankhwala, ndi ma TV ena kuti akwaniritse zofunikira zopangira.
6. Makampani oteteza zachilengedwe: amagwiritsidwa ntchito kudula zofalitsa monga zinyalala ndi matope, ndikukwaniritsa magwiridwe antchito achitetezo cha chilengedwe.
4,Kusamala posankha ma valve otseka
1. Sankhani zida zoyenera za valve malinga ndi momwe zimakhalira (monga corrosiveness, kutentha, kuthamanga, etc.).
2. Sankhani mtundu woyenera wa valavu molingana ndi kukakamiza kwa mapangidwe, kutentha kwapangidwe, ndi mainchesi a payipi.
3. Ganizirani njira yoyendetsera galimotoyo ndikusankha ma valve a manual, magetsi, kapena pneumatic shut off malinga ndi malo ndi zofunikira.
4. Ganizirani za malo oyika ndi malangizo a valve kuti muwonetsetse kuti ntchito yake ikuyenda bwino.
5. Sankhani ma valve opangidwa ndi opanga olemekezeka kuti atsimikizire ubwino ndi ntchito zogulitsa pambuyo pa ma valve.
Mwachidule, kusankha kolondola kwa ma valve otseka kumafuna kulingalira kwathunthu za katundu wa sing'anga, mapangidwe a mapaipi, ndi zochitika zogwiritsira ntchito. Ndikukhulupirira kuti bukhuli ndi lothandiza kwa inu.
