Kodi pali kusiyana kotani pakati pa valavu yoyesera ndi valavu ya mpira?

Chiyambi

Ma valavu ndi ngwazi zosayamikirika za machitidwe amadzimadzi a mafakitale, zomwe zimagwira ntchito ngati malo owongolera kuyenda, kuthamanga, ndi komwe akupita. Kwa mainjiniya, opanga mapulani, ndi akatswiri ogula, kusankha valavu yolakwika kungayambitse kusagwira bwino ntchito kwa makina, nthawi yotsika mtengo yogwira ntchito, kapena kulephera kwakukulu. Pakati pa mitundu yofala kwambiri koma yosokonezeka nthawi zambiri ndi iyivalavu ya mpirandivalavu yoyezeraNgakhale nthawi zina zingawoneke zofanana, zolinga zawo zimakhala zosiyana kwambiri. Bukuli lipereka kufananiza momveka bwino komanso mwatsatanetsatane kuti likupatseni mphamvu yosankha bwino ntchito yanu.

Kodi Valavu ya Mpira ndi Chiyani? Chipangizo Chowongolera Kuyenda Mosiyanasiyana

Avalavu ya mpirandi valavu yozungulira yozungulira kotala yomwe imagwiritsa ntchito mpira wopanda kanthu, wozungulira kuti ilamulire kuyenda kwa madzi. Chogwirira cha valavu chikazunguliridwa, mpirawo umazungulira. Bowo (bowo) pakati pa mpirawo limagwirizana ndi njira yoyendera madzi kuti lilole kuti magetsi adutse kapena kukhala mopingasa kuti litseke kwathunthu.

Kapangidwe ndi Magwiridwe Antchito Apakati

Ntchito yaikulu ya valavu ya mpira ndikugwira ntchito ngatichipangizo chozimitsa/kutsekaImapereka chitseko chodalirika, cholimba ngati thovu ndipo imadziwika ndi mphamvu yake yabwino kwambiri yozimitsa, kutsika pang'ono kwa mphamvu, komanso kugwira ntchito mwachangu.

wambaMitundu ya Ma Vavu a Mpira

• Valavu ya Mpira ya Chitsulo Chosapanga Dzimbiri: Yabwino kwambiri pa malo owononga, kugwiritsa ntchito zinthu zoyera kwambiri, komanso kutentha kwambiri. Amagwiritsidwa ntchito kwambiri m'mafakitale opanga mankhwala, zakudya ndi zakumwa, komanso mankhwala.

•Vavu ya Mpira wa MafakitaleGulu lalikulu lopangidwira kugwiritsidwa ntchito kwambiri mu mafuta ndi gasi, kukonza madzi, ndi magetsi. Nthawi zambiri amakhala ndi zomangamanga zolimba komanso zinthu zolimba monga chitsulo cha kaboni.

•Ma Vavu a Mpira Odzichitira Pawokha: Yokhala ndi ma actuator amagetsi, opumira mpweya, kapena a hydraulic kuti azilamulira kutali ndi kuphatikiza mu machitidwe odzipangira okha.

•Valavu ya Mpira Wopindika: Ili ndi ulusi wa NPT kapena BSPT kuti ukhale wosavuta kuyika m'mapaipi ang'onoang'ono popanda kuwotcherera.

•Valavu ya Mpira wa Hydraulic: Yopangidwa mwapadera kuti igwire ntchito yolimbana ndi kupsinjika kwakukulu komwe kumapezeka mumakina a hydraulic, omwe nthawi zambiri amapangidwa ndi kaboni wamphamvu kwambiri kapena chitsulo chosapanga dzimbiri.

Kodi Valvu Yoyang'anira ndi Chiyani? Mlonda wa Njira Yoyendetsera Mayendedwe

Avalavu yoyezera, kapena valavu yosabwerera (NRV), ndi chipangizo chodzitetezera chokha chomwe chimapangidwa kuti chilole madzi kuyenda mbali imodzi yokha. Cholinga chake chokha ndikuletsa kuyenda kobwerera m'mbuyo komwe kungawononge komanso kusagwira ntchito bwino (kubwerera m'mbuyo).

Kapangidwe ndi Magwiridwe Antchito Apakati

Thentchito yowunikira valavusichifuna kulamulira ndi manja kapena kunja. Kuyenda kokha kumatsegula valavu. Kuyenda kukayima kapena kubwerera m'mbuyo, njira yamkati (diski, mpira, kapena diaphragm) imatseka yokha kudzera mu mphamvu yokoka, mphamvu ya masika, kapena kupsinjika kwa kumbuyo.

Mitundu Yodziwika ya Ma Valves Oyang'anira

•Valavu Yowunikira Mpira: Imagwiritsa ntchito mpira woyandama wokhazikika womwe umakhala moyandikana ndi chisindikizo kuti uletse kuyenda kwa mpweya m'mbuyo. Ndi wosavuta komanso wogwira ntchito pa ntchito zosiyanasiyana.

•Valavu Yowunikira Yozungulira: Ili ndi diski yokhala ndi hinge yomwe imatseguka ndi madzi otuluka ndipo imatsekeka motsutsana ndi chisindikizo madzi akabwerera m'mbuyo. Imapezeka kwambiri m'madzi ndi m'mizere yamadzi otayira.

•Valavu Yoyang'ana Yozungulira: Yokhala ndi malekezero opindika kuti ilumikize maboliti ku mapaipi amphamvu kapena akuluakulu, kuonetsetsa kuti chisindikizocho chili cholimba komanso chosatulutsa madzi.

•Valavu Yoyang'ana Yokhala ndi UlusiMofanana ndi ma valve a mpira okhala ndi ulusi, awa amapangidwira kuti aziyika mosavuta m'makina ang'onoang'ono.

Kusiyana Kwakukulu: Chongani Valve vs Valavu ya Mpira

Tebulo ili likufotokoza kusiyana kwakukulu pakati pa valavu ya mpira ndi valavu yowunikira. 

*Kupopera ndi valavu ya mpira wamba sikuvomerezeka chifukwa kungayambitse kutsekeka kwa zitseko ndi kukokoloka kwa mipando. Vavu ya mpira yodziwika bwino kapena V-port imagwiritsidwa ntchito polamulira.

Pakatikatikusiyana pakati pa valve ya mpira ndi valve yowunikirandi kulamulira poyerekeza ndi kudzipangira wekha. Avalavu ya mpirandi zamwachindunji, kulamulira mwadalal ya kuyenda. Avalavu yoyezerandi zazokha, chitetezo chosachitapo kanthuya dongosolo.

Kugwiritsa Ntchito ndi Nkhani Zogwiritsira Ntchito: Kusankha Chida Choyenera Pantchito

Kumene Mungagwiritsire Ntchito Valavu ya Mpira

•Kudzipatula:Kutseka gawo la chitoliro kuti chikonzedwe.

•Kuwongolera Njira:Monga valavu yodalirika yoyatsira/kutseka mu mzere uliwonse wopangira.

•Kugawa:Kutsogolera kuyenda kwa madzi ku nthambi zosiyanasiyana za dongosolo.

•Chitetezo:Malo otsekeredwa mwadzidzidzi chifukwa cha madzi oopsa.

Kumene Mungagwiritsire Ntchito Valve Yoyang'anira

•Chitetezo cha Pampu:Imayikidwa mbali yotulutsira madzi ya pampu kuti isabwererenso ndipo imathira madzi pampu ikasiya kutuluka.

•Kupewa Kubwerera M'mbuyo:Kuonetsetsa kuti madzi oipitsidwa sabwerera m'madzi oyera.

•Kukhulupirika kwa Dongosolo:Kusunga kupanikizika mumzere ndikuletsa kutuluka kwa madzi (monga mu machitidwe a HVAC).

•Kulekanitsa Atolankhani:Kuletsa zinthu ziwiri zosiyana kuti zisasakanikirane mu mzere wofanana.

Njira Zabwino Zokhazikitsira ndi Kusamalira

Kuyika kwa Valve Yoyang'ana

Kukhazikitsa bwino valavu yowunikira ndikofunikira kuti igwire bwino ntchito.

1. Malangizo:Muvi womwe uli pa thupi la valavu uyenera kuloza komwe madzi akuyenda.

2. Kulankhulana:Ma valve ambiri oyesera (makamaka mitundu yozungulira) ayenera kuyikidwa mopingasa. Ena, monga ma valve oyesera mpira, angagwire ntchito mopingasa ndi kuyenda kokwera. Nthawi zonse funsani zomwe wopanga akufuna.

3. Kuchotsera:Onetsetsani kuti chitoliro cholunjika cha valavu chikuyenda bwino musanayambe komanso pambuyo pake kuti chikhale chosavuta kusuntha ndi kuyenda bwino kwa disc.

Malangizo Osamalira Ma Valves a Mpira

Ngakhale kuti nthawi zambiri sizimasamalidwa bwino, ma valve a mpira wa mafakitale amapindula ndi macheke a nthawi ndi nthawi.

1. Kukwera njinga:Yesetsani ma valve nthawi ndi nthawi (tsegulani/tsekani) kuti mupewe kugwidwa, makamaka m'malo omwe simunagwire ntchito.

2. Kuyang'anira Kutayikira kwa Madzi:Yang'anani zomatira za tsinde ndi mpando kuti zisamatuluke.

3. Kuyang'ana kwa Actuator:Pa ma valve a mpira odziyimira pawokha, tsimikizirani gwero la mphamvu ya actuator, ma switch oletsa, ndi makonda a torque.

4. Mafuta odzola:Ma valve ena amafunika kudzola mafuta nthawi ndi nthawi pa tsinde pogwiritsa ntchito choyika mafuta.

Mapeto: Nkhani ya Ntchito, Osati Zokonda

Kusankha pakati pa valavu ya mpira ndi valavu yoyezera si nkhani yoti ndi iti yabwino, koma ndi iti yoyenera ntchitoyo. Amapangidwira zolinga zosiyana kwambiri.

• Sankhani Valavu ya Mpiramukafunakulamulira kogwira ntchito, kamanja, kapena kodzichitira zokhakuyambitsa kapena kuyimitsa kuyenda.

• Sankhani Valve Yowunikiramukafunachitetezo chokhazikika, chodzitetezera chokhakuti aletse kuyenda kwa madzi m'njira yobwerera m'mbuyo.

Pa makina ovuta, nthawi zambiri amawaona akugwira ntchito limodzi—mongavalavu ya mpirakudzipatula ndivalavu yoyezeraPampu yomweyo pansi pa madzi kuti mutetezedwe. Mukamvetsetsa ntchito zawo zosiyanasiyana, mutha kusankha ma valve molimba mtima, kuonetsetsa kuti makinawo akugwira ntchito bwino, otetezeka, komanso kuti azikhala nthawi yayitali.

Kodi mwakonzeka kusankha valavu yoyenera polojekiti yanu? Yang'anani mndandanda wathunthu wa ntchito zapamwamba ku NSWmavavu a mpira osapanga dzimbirindi odalirikama valve owunikirakuti mupeze yankho labwino kwambiri pa ntchito yanu.
