Valavu ya Mpira wa Trunnion vs Floating: Ndi iti yomwe ili yoyenera kugwiritsa ntchito kwanu?

Pali kusiyana kwakukulu pakati paMa valve a mpira wa TrunnionndiMa valve a mpira oyandamaPonena za kapangidwe kake, mfundo yogwirira ntchito, magwiridwe antchito ndi nthawi yogwiritsira ntchito. Izi ndi kufananiza mwatsatanetsatane kwa ziwirizi:

Kusiyana kwa Kapangidwe ka Trunnion ndi Floating Ball Valve

Vavu ya Mpira wa Trunnion

• Mpirawu umalumikizidwa mokhazikika ku ma valvu apamwamba ndi apansi. Mpirawu umangozungulira mozungulira tsinde la valvu ndipo sungayende momasuka m'thupi la valvu.
• Ma valvu apamwamba ndi apansi amalumikizidwa mwamphamvu ndi mpira, zomwe zimaletsa kuyenda kwa mpirawo pamodzi.

Vavu Yoyandama ya Mpira

• Mpirawo ukuyandama, ndiko kuti, palibe mgwirizano wokhazikika pakati pa mpirawo ndi mpando wa valavu, ndipo mpirawo ukhoza kuyenda momasuka m'thupi la valavu.
• Kawirikawiri tsinde limodzi lokha la valavu la pansi limalumikizidwa ku mpira, ndipo tsinde la valavu lapamwamba nthawi zambiri limagwira ntchito yotumiza mphamvu yokha ndipo silimakhazikika mwachindunji ku mpirawo.

Mfundo Yogwirira Ntchito

1. Valavu ya mpira wa Trunnion

• Kulumikizana kolimba ndi kutseka pakati pa mpira ndi mpando wa valavu kumachitika kudzera mu kuyika patsogolo pakati pa mpira ndi mpando wa valavu ndi kutumiza kwa tsinde la valavu.
• Mphamvu ya mpira imafalikira mofanana kudzera m'magawo apamwamba ndi otsika a valavu, ndipo kuzungulira kwa mpira kumakhala kosalala ndipo mphamvu yake imakhala yofanana.

2. Valavu ya mpira yoyandama

• Ikatsekedwa, mphamvu yapakati imakankhira mpirawo ku mpando wa valavu yotulukira, kotero kuti mpirawo ndi mpando wa valavu zigwirizane bwino kuti zitseke. Mphamvu yapakati ikachuluka, mphamvu yapakati imatsekeka bwino.
• Mphamvu ya mpira imafalikira makamaka ku mpira kudzera mu tsinde la valavu la pansi, ndipo tsinde la valavu lapamwamba limathandiza kufalitsa. Panthawi yotsegulira ndi kutseka, mphamvu ya mpira imakhala yovuta.

Makhalidwe Ogwira Ntchito

1. Valavu ya mpira wa Trunnion

• Kugwira ntchito kokhazikika kotseka, kosakhudzidwa ndi kusinthasintha kwapakati pa kuthamanga.
• Kapangidwe kake ndi kovuta, mawonekedwe ake onse ndi olimba pang'ono, ndipo thupi la valavu nthawi zambiri limakhala lolimba.
• Yoyenera makina a mapaipi okhala ndi mphamvu yothamanga kwambiri, komanso nthawi zina zomwe zimafunika kwambiri kuti zitseke bwino komanso kuti madzi aziyenda bwino.

2. Valavu ya mpira yoyandama

• Ngati kupanikizika kwapakati kuli kochepa kapena palibe kupanikizika kwapakati, magwiridwe antchito otseka angakhudzidwe pang'ono.
• Kapangidwe kake konse ndi kosavuta, mawonekedwe ake ndi ochepa, ndipo voliyumu yake nthawi zambiri imakhala yaying'ono.
• Amagwiritsidwa ntchito kwambiri m'mapaipi apakati ndi otsika, mapaipi ang'onoang'ono opingasa, komanso nthawi zina pamafunika ukhondo wapakati komanso kuthamanga kwapakati kokhazikika.

Mapulogalamu

1. Valavu ya mpira wa Trunnion

Yoyenera kwambiri pazochitika za kuthamanga kwambiri, zazikulu, monga machitidwe ofunikira a mapaipi mu petrochemical, kutumiza gasi lachilengedwe, magetsi ndi mafakitale ena.

Yoyenera nthawi zina zomwe zimafuna kutseka mbali ziwiri, chifukwa kapangidwe ka mpando wa valavu ya valavu yokhazikika kangathandize kuonetsetsa kuti valavuyo imatsekedwa mbali zonse ziwiri.

2. Valavu ya mpira yoyandama

Amagwiritsidwa ntchito kwambiri m'mafakitale a mankhwala, mafuta, gasi wachilengedwe ndi zitsulo, makamaka pa mapaipi a gasi wachilengedwe omwe ali ndi hydrogen sulfide media, zinyalala kapena dzimbiri lalikulu.

Komanso yoyenera pazochitika zomwe zimafuna ukhondo wapakati komanso mphamvu yapakati yokhazikika, monga madzi wamba ndi njira zotulutsira madzi, makina oziziritsira mpweya, ndi zina zotero.

Powombetsa mkota

Ma valve a mpira wa Trunnion ndi ma valve a mpira woyandamaChilichonse chili ndi kapangidwe kake kapadera komanso makhalidwe ake, oyenera kugwiritsidwa ntchito mosiyanasiyana. Posankha, kuganizira mozama kuyenera kuperekedwa pazinthu monga mikhalidwe yeniyeni yogwirira ntchito, makhalidwe apakati ndi zofunikira pakutseka.
