Momwe mungadziwire valavu ya chipata ndi valavu yozungulira: Malangizo ochokera ku fakitale

Gate Valve vs Globe Valve: Kusiyana Kwakukulu, Kugwiritsa Ntchito, ndi Kuzindikira

Mapaipi a mafakitale amadalira njira yoyendetsera bwino kayendedwe ka madzi, zomwe zimapangitsa kusankha mavavu kukhala kofunika kwambiri. Mitundu iwiri yofunikira—mavavu a pachipata ndi mavavu ozungulira—amatumikira ntchito zosiyanasiyana ngakhale kuti amafanana m'mawonekedwe. Bukuli likufotokoza kusiyana kwawo, kagwiritsidwe ntchito kawo, ndi njira zodziwira.

Kodi Valavu ya Chipata ndi Chiyani?

Valavu ya chipataimayendetsa kuyenda kwa madzi mwa kukweza kapena kutsitsa “chipata” chooneka ngati makona anayi kapena chooneka ngati mphero kudzera mu tsinde lokhala ndi ulusi. Zinthu zofunika:

Ntchito: Yotseguka/yotsekedwa kwathunthu yokha; yosayenera kuponderezedwa.

Njira YoyenderaKapangidwe kolunjika kamachepetsa kutsika kwa kuthamanga kwa magazi.

Kutseka: Zimatseka mwamphamvu mukatseka kwathunthu, ndipo chiopsezo chotaya madzi chichepa.

Mapulogalamu: Ma petrochemicals, madzi, mapaipi akuluakulu omwe ali ndi mulifupi mwake komwe kukana kuyenda kwa madzi ndikofunikira.

Chitsanzo:Mu makina amadzi a m'matauni, ma valve a zipata amalekanitsa zigawo panthawi yokonza chifukwa chakuti sagwira ntchito bwino akatsegulidwa.

Kodi Valavu Yozungulira Ndi Chiyani?

Valavu ya dziko lapansi(kapena valavu yoyimitsa) imayendetsa kayendedwe ka madzi pogwiritsa ntchito diski kapena pulagi yomwe imakanikiza molunjika pa mpando. Zinthu zofunika:

Ntchito: Yapangidwira kuti igwire ntchito pafupipafupi komanso kuti igwire ntchito pafupipafupi.

Njira Yoyendera: Seti yooneka ngati S imawonjezera kukana koma imalola kulamulira kolondola.

Kutseka: Njira yotsekera mokakamiza imafuna mphamvu yokwanira yotsekera.

Mapulogalamu: Maboiler, HVAC, makina a nthunzi—malo aliwonse omwe amafunika kusintha kayendedwe ka madzi.

Chitsanzo: Ma valve a globe amayendetsa kayendedwe ka nthunzi m'mafakitale amagetsi, zomwe zimathandiza ogwiritsa ntchito kukonza bwino kuthamanga kwa mpweya.

Kusiyana Kwakukulu: Gate Valve vs Globe Valve

Momwe Mungadziwire Ma Vavulopu a Chipata ndi Ma Vavulopu a Globe

1. Kuyang'ana Zooneka:

Valavu ya Chipata: Thupi lalitali (makamaka mitundu ya tsinde lokwera); chiwongolero cha chiguduli chamanja chimakwezedwa valavu ikatsegulidwa.

Valavu Yozungulira: Thupi lozungulira; kutalika kwa tsinde lalifupi.

2. Njira Yoyendera:

Ma valve a chipata amalola kuyenda kwa mbali ziwiri.

Ma valve ozungulira ali ndi mivi yolunjika yomwe imaponyedwa pa thupi.

3. Ntchito ya chiguduli chamanja:

Ma valve a chipata amafunika kuzungulira kangapo kuti atsegule/atseke.

Ma valve a globe amatseguka/kutseka mwachangu (kuyenda kwafupikitsa kwa tsinde).

Nthawi Yogwiritsira Ntchito Valve Iliyonse

Sankhani Ma Valves a Chipata:

1. Kupatula madzi okwanira m'mapaipi amadzi/mafuta.

2. Machitidwe ochepetsa mphamvu ya mpweya (monga mayendedwe akutali).

3. Kugwira ntchito kosachitika kawirikawiri (monga kutsekedwa kwadzidzidzi).

Sankhani Ma Valves a Globe:

1. Kulamulira kayendedwe ka madzi (monga, njira zoziziritsira).

2. Kugwira ntchito pafupipafupi (monga kusintha kwa tsiku ndi tsiku).

3. Kugwiritsa ntchito nthunzi/mpweya wochuluka.

Chifukwa Chake Kusankha Ma Valve N'kofunika

Kusankha valavu yolakwika kumabweretsa mavuto kapena kulephera kwa dongosolo. Mavalavu a pachipata amawonjezera kuyenda kwa madzi m'malo otseguka koma amatuluka pang'ono ngati atsekedwa pang'ono. Mavalavu a globe amapereka mphamvu koma amawonjezera ndalama zamagetsi chifukwa cha kukana. Nthawi zonse gwirizanitsani mtundu wa valavu ndi zofunikira pakugwira ntchito—kuonetsetsa kuti chitetezo, moyo wautali, komanso magwiridwe antchito apamwamba.

Malangizo a Akatswiri:Pa makina amphamvu kwambiri, phatikizani ma valve a chipata (kupatula kwakukulu) ndi ma valve ozungulira (kulamulira kolondola) kuti mupeze zotsatira zabwino kwambiri.
