Kusiyana Pakati pa Chipata ndi Valavu mu Kulamulira Kuyenda kwa Madzi
Kulamulira kuyenda kwa madzi m'mapaipi ndi gawo lofunika kwambiri pa ntchito zosiyanasiyana zamafakitale ndi zapakhomo. Chinthu chimodzi chofunikira pakuwongolera kuyenda kwa madzi ndi kugwiritsa ntchito zipangizo zowongolera kuyenda kwa madzi monga zipata ndi mavalavu. Ngakhale zonse ziwiri zimagwira ntchito yowongolera kuyenda kwa madzi, pali kusiyana kwakukulu pakati pa zipata ndi mavalavu pankhani ya kapangidwe, kagwiritsidwe ntchito, kagwiritsidwe ntchito, ndi kagwiritsidwe ntchito ka madzi. Nkhaniyi ifufuza kusiyana pakati pa zipata ndi mavalavu pakuwongolera kuyenda kwa madzi.
Chipata Chomvetsetsa
Chipata, chomwe chimadziwikanso kuti valavu ya chipata, ndi mtundu wa valavu yomwe imagwiritsidwa ntchito kutsegula ndi kutseka kuyenda kwa madzi mu dongosolo la mapaipi. Kapangidwe ka valavu ya chipata kamalola kuwongolera kuyenda kwa madzi mwa kuyika chipata chomwe chimayenda molunjika mmwamba ndi pansi kuti chitsegule kapena kutseka njira yoyendera madzi.
Kapangidwe ndi Kugwira Ntchito kwa Valavu ya Chipata
Valavu ya chipata imakhala ndi zigawo zazikulu monga thupi, chipata, spindle (tsinde), ndi wheel drive. Pamene wheel drive watembenuzidwa, spindle imakwera kapena kutsika, yomwe imasuntha chipata mmwamba kapena pansi kuti itsegule kapena kutseka madzi. Potseguka kwathunthu, chipatacho chimakhala kunja kwa njira ya madzi, zomwe zimapangitsa kuti madzi aziyenda bwino popanda chopinga chachikulu.
Ubwino wa Valavu ya Chipata
1. Kukana Kuyenda kwa Madzi: Chipata chikatsegulidwa bwino, palibe kukana kuyenda kwa madzi, zomwe zikutanthauza kuti kukana kuyenda kwa madzi kumakhala kochepa kwambiri.
2. Yolimba: Ma valve a chipata amakhala olimba kwambiri ndipo angagwiritsidwe ntchito pamavuto osiyanasiyana komanso kutentha.
3. Kugwiritsa Ntchito Kwambiri: Ma valve a zipata nthawi zambiri amagwiritsidwa ntchito pazinthu zomwe zimafuna kutsegula/kutseka kwathunthu kwa madzi, monga m'mapaipi akuluakulu a makina ogawa madzi kapena mapaipi akuluakulu m'mafakitale.
Zoyipa za Valavu ya Chipata
1. Nthawi Yaitali Yotseka: Ma valve a chipata amatenga nthawi yayitali kuti atsegulidwe kapena kutsekedwa kwathunthu chifukwa cha nthawi yayitali yoyendera.
2. Kukonza Kovuta Kwambiri: Chifukwa cha kapangidwe kake kovuta, kukonza ndi kukonza ma valve a chipata kungakhale kovuta kwambiri.
3. Kutaya madzi: Pazifukwa zina, valavu ya chipata ikhoza kutuluka madzi, makamaka ngati chitseko cha valavu kapena mpando wake wawonongeka.
Kumvetsetsa Ma Valves
Valavu, munkhaniyi nthawi zambiri imatanthauza valavu yozungulira kapena valavu ya mpira, ndi chipangizo chomwe chimagwiritsidwa ntchito kulamulira, kuwongolera, kapena kuwongolera kuyenda kwa madzi mwa kutsegula, kutseka, kapena kuletsa pang'ono kuyenda kwa madzi.
Kapangidwe ka Valavu ya Globe ndi Momwe Imagwirira Ntchito
Ma valve ozungulira ali ndi kapangidwe kake ka thupi lokhala ndi chipinda chozungulira chamkati chomwe chimalekanitsa kuyenda kwa madzi m'mbali ziwiri. Kuti azitha kuyendetsa bwino, ma valve ozungulira amagwiritsa ntchito disc kapena pulagi yomwe ingakwezedwe kapena kutsitsidwa ndi tsinde la valve, lomwe limayendetsedwa ndi gudumu loyendetsa. Disc ikakhala pafupi ndi mpando wa valve, kuyenda kwake kumatsekedwa kapena kuyimitsidwa.
Kapangidwe ndi Kugwira Ntchito kwa Valavu ya Mpira
Ma valve a mpira amagwiritsa ntchito mpira wozungulira, woboola potsegula kapena kutseka kayendedwe ka madzi. Mpira ukazunguliridwa motsatira kayendedwe ka madzi, madzi amatha kudutsa m'bowo lomwe lili pakati pa mpira; mpira ukazunguliridwa madigiri 90, madziwo amasiya kutuluka.
Ubwino wa Globe Valve
1. Kuwongolera Kuyenda Molondola: Ma valve ozungulira amapereka njira yowongolera kuyenda bwino kuposa ma valve a pachipata, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito komwe kumafunikira njira inayake yoyendetsera kuyenda.
2. Kuyankha Mwachangu: Ma valve a globe ali ndi nthawi yoyankha mwachangu potsegula kapena kutseka kayendedwe ka madzi.
3. Ntchito Zambiri: Zimagwiritsidwa ntchito powongolera pang'ono kayendedwe ka madzi m'malo otenthetsera, mpweya wabwino, komanso madzi othamanga kwambiri.
Ubwino wa Valavu ya Mpira
1. Kugwira Ntchito Mwachangu: Kutsegula kapena kutseka valavu ya mpira kumafuna kuzungulira kwa madigiri 90 okha, zomwe zimapangitsa kuti ntchito igwire ntchito mwachangu kwambiri.
2. Kutaya madzi pang'ono: Ikatsekedwa bwino, valavu ya mpira imapereka chisindikizo cholimba kwambiri, zomwe zimachepetsa chiopsezo cha kutuluka madzi.
3. Kukonza Mosavuta: Kapangidwe kosavuta ka valavu ya mpira kumapangitsa kuti ikhale yosavuta kusamalira ndi kukonza.
Zoyipa za Globe Valve
1. Kukana Kuyenda Kwambiri: Chifukwa cha kapangidwe kake kamkati, ma valve ozungulira amachititsa kuti madzi aziyenda bwino kuposa ma valve a pachipata.
2. Kutaya Mphamvu: Ma valve ozungulira nthawi zambiri amayambitsa kutsika kwakukulu kwa mphamvu, zomwe zingayambitse kutayika kwa mphamvu mu dongosolo la mapaipi.
Zoyipa za Ma Valves a Mpira
1. Kusintha Kwambiri: Muzochitika zovuta kwambiri, ma valve a mpira amatha kusintha zomwe zimakhudza magwiridwe antchito.
2. Kugwiritsa Ntchito Mochepa: Sikugwira ntchito bwino ngati ma valve ozungulira omwe amafunikira kuwongolera bwino kayendedwe ka madzi.
Kusiyana Kwakukulu Pakati pa Chipata ndi Valve
1. Kapangidwe ndi Njira:
- Ma valve a pachipata amagwiritsa ntchito chitseko chomwe chimakwera ndi kutsika kuti chitsegule kapena kutseka madzi, pomwe ma valve ozungulira amagwiritsa ntchito diski kapena pulagi, ndipo ma valve a mpira amagwiritsa ntchito mpira wopanda kanthu.
2. Ntchito Zazikulu:
- Ma valve a pachipata nthawi zambiri amagwiritsidwa ntchito potsegula/kutseka kwathunthu. Ma valve a globe ndi ma valve a mpira ndi oyenera kwambiri pa ntchito zomwe zimafuna kulamulira kapena kuwongolera kayendedwe ka madzi.
3. Kukana Kuyenda kwa Madzi:
– Ma valve a pachipata amapereka mphamvu yoyenda popanda kukana kwakukulu akatsegulidwa kwathunthu. Ma valve a globe amakhala ndi mphamvu yoyenda bwino chifukwa cha kapangidwe kake. Ma valve a mpira amapereka mphamvu yoyenda popanda kukana kwakukulu, koma akatsekedwa kwathunthu.
4. Liwiro Logwira Ntchito:
- Ma valve a globe ndi ma valve a mpira ali ndi nthawi yoyankha mwachangu kuposa ma valve a chipata.
5. Kulimba ndi Kusamalira:
– Ma valve a pachipata amakhala ndi nthawi yayitali yogwira ntchito ndipo amafunika kukonza kovuta. Ma valve ena, monga ma valve a mpira, amakhala ndi nthawi yayitali yogwira ntchito ndipo amafunika kukonza kosavuta.
Mapeto
Kusankha pakati pa chipata ndi valavu kumadalira zofunikira zinazake zogwiritsira ntchito, kuphatikizapo mtundu wa kayendedwe ka madzi, liwiro lowongolera, ndi momwe zimagwirira ntchito. Mavalavu a chipata ndi oyenera kwambiri kugwiritsa ntchito potsegula/kutseka kwathunthu ndi kayendedwe ka madzi komasuka, pomwe mavalavu a globe ndi ball ndi oyenera kwambiri powongolera kayendedwe ka madzi mwachangu. Kumvetsetsa kusiyana kumeneku ndikofunikira kwambiri kuti zitsimikizire kuti njira yopaipi ikugwira ntchito bwino komanso bwino poyendetsa kayendedwe ka madzi.
