Chipata Chovala VS Globe Valve Mu Ntchito Zam'madzi

M'madera a m'nyanja, kusankha valavu yoyenera n'kofunika kwambiri kuti muzitha kuyendetsa bwino madzimadzi ndikuwonetsetsa chitetezo ndi moyo wautali wa kayendedwe ka sitima. Mitundu iwiri ya ma valve omwe amagwiritsidwa ntchito kwambiri m'madzi am'madzi ndima valve pachipatandima valve a globe. Ngakhale kuti zonsezi zinapangidwa kuti ziziyendetsa kayendedwe ka madzi ndi mpweya, zimagwira ntchito zosiyanasiyana ndipo zimagwira ntchito mosiyanasiyana. Kumvetsetsa kusiyana kwawo kungathandize oyendetsa sitimayo kupanga zisankho zodziwika bwino, kuonetsetsa kuti akugwira ntchito bwino m'mikhalidwe yovuta.

1. Mapangidwe ndi Ntchito

Vavu ya Gate:

• Valavu yachipata imagwira ntchito pokweza kapena kutsitsa chipata (kapena wedge) mkati mwa thupi la valve kuti ayambe kapena kuyimitsa kutuluka.
• Amapereka kutuluka kosasunthika pamene kutseguka kwathunthu, kuchepetsa kutaya kwa kuthamanga.
• Yoyenera kwambiri malo otseguka kapena otsekedwa kwathunthu komanso osati yabwino kugwedeza.
• Kusiyanasiyana kwa mapangidwe kumaphatikizapo mitundu ya tsinde yokwera ndi yosakwera.

Globe Valve:

• Valavu yoyimitsa imagwiritsa ntchito chimbale chomwe chimayenda motsutsana ndi njira yolowera kuti chiwongolere kapena kuyimitsa madziwo.
• Mapangidwe a valve amalola kuwongolera bwino komanso kusuntha kwakuyenda.
• Kapangidwe kake kamakhala ndi tsinde lomwe limayenda molunjika kumpando.
• Amapereka kusindikiza bwino komanso kuyendetsa bwino, koma kumabweretsa kutsika kwakukulu.

2. Mapulogalamu mu Marine Systems

Mapulogalamu a Gate Valve:

• Ndi abwino pamakina omwe amafunikira kutsika pang'ono, monga madzi a m'nyanja, madzi a ballast, ndi makina amafuta.
• Amagwiritsidwa ntchito popatula magawo a mapaipi.
• Oyenera kunyamula madzi ambiri okhala ndi zoletsa zochepa.

Ntchito za Globe Valve:

• Zofala m'makina omwe amafunikira kuwongolera bwino kayendedwe kake, monga mizere yamadzi ozizira, makina opaka mafuta, ndi kugwiritsa ntchito nthunzi.
• Amagwiritsidwa ntchito m'malo omwe kugunda kapena kusintha kwapang'onopang'ono ndikofunikira.
• Nthawi zambiri amagwiritsidwa ntchito m'machitidwe a bilge ndi ballast komwe kuwongolera bwino kumafunika.

3. Ubwino ndi Kuipa kwake

Ubwino wa Vavu ya Gate:

• Kukana kuyenda pang'ono kukatsegula kwathunthu.
• Kumanga kosavuta ndi kukonza kochepa.
• Zokhalitsa komanso zoyenera kumadera opanikizika kwambiri.

Kuipa kwa Vavu ya Gate:

• Osayenerera kugwedeza; Kutsegula pang'ono kungayambitse kukokoloka ndi kuwonongeka.
• Kuchita pang'onopang'ono poyerekeza ndi ma valve oyimitsa.

Ubwino wa Globe Valve:

• Kuwongolera koyenda bwino komanso kuthekera kwapang'onopang'ono.
• Amapereka kusindikiza kolimba, kuchepetsa kuopsa kwa kutayikira.
• Imagwira ntchito bwino pansi pazifukwa zosiyanasiyana.

Kuipa kwa Globe Valve:

• Kuthamanga kwapamwamba kutsika chifukwa cha mapangidwe.
• Zomangamanga zovuta kwambiri, zomwe zimapangitsa kuti pakhale zofunikira zokonza.

4. Kukaniza kwa Corrosion ndi Kusankha Zinthu

Ma valve a zipata ndi Globe omwe amagwiritsidwa ntchito panyanja nthawi zambiri amapangidwa kuchokera ku zinthu zomwe zimakana dzimbiri, monga:

• Bronze- Zodziwika pakugwiritsa ntchito madzi am'nyanja.
• Chitsulo chosapanga dzimbiri- Amapereka kukana kwa dzimbiri komanso mphamvu.
• Cast Iron yokhala ndi Epoxy Coating- Amagwiritsidwa ntchito m'makina osafunikira kwambiri kuti athe kulinganiza mtengo ndi kulimba.

Kusankha zinthu moyenera ndikofunikira kuti zisawonongeke m'madzi, kuwonetsetsa kuti moyo wautali komanso kuchepetsa ndalama zosamalira.

5. Mfundo zazikuluzikulu za Oyendetsa Panyanja

• Zofunikira pakuyenda:Ngati kuchepa kwapang'onopang'ono kuli kofunikira, ma valve a zipata amakondedwa.
• Zofunikira pakuwongolera:Kuti muyende bwino bwino, ma valve oyimitsa amapereka ntchito yabwino.
• Kupezako Kukonza:Ma valve oyimitsa angafunike kukonzedwa pafupipafupi koma amapereka kusindikiza bwino.
• Kupanga Kwadongosolo:Ganizirani za malo ndi momwe mapaipi amayendera posankha pakati pa tsinde lokwera kapena mavavu apachipata osakwera.
