Kodi pali kusiyana kotani pakati pa valavu yapadziko lonse ndi valve yachipata?

Vavu ya globe ndi valavu ya pachipata ali ndi mawonekedwe ofanana, ndipo onsewa ali ndi ntchito yodula mapaipi, kotero anthu nthawi zambiri amadzifunsa kuti, pali kusiyana kotani pakati pa valavu yapadziko lonse ndi valavu yachipata?

Globe valve, valve gate,valavu ya butterfly, valavu yoyendera ndi valavu ya mpira zonse ndizofunikira kwambiri pakuwongolera mapaipi osiyanasiyana. Vavu yamtundu uliwonse ndi yosiyana m'mawonekedwe, kapangidwe kake komanso magwiridwe antchito. Koma valavu yapadziko lonse ndi valve yachipata zimakhala ndi zofanana mu mawonekedwe, ndipo panthawi imodzimodziyo zimakhala ndi ntchito yodula payipi, kotero padzakhala abwenzi ambiri omwe alibe kukhudzana kwambiri ndi valve adzasokoneza awiriwo. M'malo mwake, ngati muyang'ana mosamala, kusiyana pakati pa valavu yapadziko lonse lapansi ndi valavu yachipata ndi yayikulu kwambiri. Nkhaniyi iwonetsa kusiyana pakati pa valavu yapadziko lonse lapansi ndi valavu yachipata.

1. Mfundo yosiyana yogwiritsira ntchito pakati pa valavu yapadziko lonse ndi valve yachipata
Pamene valavu yapadziko lonse imatsegulidwa ndi kutsekedwa, imatembenukira pa gudumu lamanja, gudumu lamanja lidzazungulira ndi kukweza pamodzi ndi tsinde la valve, pamene valve yachipata idzatembenuza gudumu lamanja kuti ikweze gudumu la valve, ndipo malo a gudumu lamanja amakhalabe osasintha.

TheVavu yokhala pachipata cha rabaraali ndi zigawo ziwiri zokha: kutsegula kwathunthu kapena kutseka kwathunthu ndi nthawi yayitali yotsegula ndi yotseka; kugunda kwa valavu yapadziko lonse lapansi kumakhala kochepa kwambiri, ndipo mbale ya valve ikhoza kuyimitsidwa pamalo ena poyendetsa kayendedwe ka kayendedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake

2. Kusiyana kwa magwiridwe antchito pakati pa valavu yapadziko lonse lapansi ndi valavu yachipata
Valve yapadziko lonse lapansi imatha kudulidwa ndikugwiritsiridwa ntchito kuwongolera kayendetsedwe kake. Kukaniza kwamadzimadzi kwa valve ya globe ndi yaikulu, ndipo n'zovuta kutsegula ndi kutseka, koma chifukwa mbale ya valve ndi yaifupi kuchokera kumalo osindikizira, kotero kuti kutsegula ndi kutseka kutsekeka kumakhala kochepa.

Valve yachipata cha BS5163 imatha kutsegulidwa ndikutsekedwa kwathunthu. Ikatsegulidwa kwathunthu, kukana kwapakati pa sing'anga mumsewu wa thupi la valve ndi pafupifupi 0, kotero kutsegula ndi kutseka kwa valve ya chipata kudzakhala kosavuta kwambiri, koma chipata chili kutali ndi kusindikiza pamwamba, ndipo nthawi yotsegula ndi yotseka ndi yaitali.

3. Kuyika kwa njira yoyendetsera kusiyana kwa valavu yapadziko lonse ndi valve yachipata
Kuthamanga kwa valve yachipata ku mbali zonse ziwiri kumakhala ndi zotsatira zofanana, kuyikako kulibe zofunikira pa njira yotumizira ndi kutumiza kunja, sing'anga imatha kuyenda mbali zonse ziwiri.

Valavu yapadziko lonse lapansi iyenera kukhazikitsidwa motsatira malangizo a muvi wa valve. Pali ndondomeko yomveka bwino yokhudzana ndi njira yolowera ndi kutuluka kwa valavu yapadziko lonse lapansi, ndipo valavu "yatatu mpaka" imasonyeza kuti njira yolowera ya valve yoyimitsa imagwiritsidwa ntchito kuchokera pamwamba mpaka pansi.

4. Kusiyana kwapangidwe pakati pa valavu ya globe ndi valve valve
Mapangidwe a valve yachipata adzakhala ovuta kwambiri kuposa valavu ya globe. Kuchokera pamawonekedwe a mainchesi omwewo, valavu yachipata iyenera kukhala yokwera kuposa valavu yapadziko lonse lapansi, ndipo valavu yapadziko lonse lapansi iyenera kukhala yayitali kuposa valve yachipata. Kuphatikiza apo, valve yachipata ili nayoTsinde LokwerandiTsinde Losakwera, valavu ya globe sichitha.
