Chifukwa Chiyani Vavu Yotulutsa Mpweya Imayikidwa Ndi Kukhazikika Pamizere Yopangira Madzi?

Thevalavu yotulutsa mpweyandi chida chofunikira pakuchotsa mwachangu gasi mupaipi, chomwe chimagwiritsidwa ntchito kukonza bwino zida zotumizira madzi ndikuteteza payipi kuti zisawonongeke komanso kuphulika.Imayikidwa pamtunda wa doko la pampu kapena mumsewu woperekera madzi ndi kugawa kuti muchotse mpweya wambiri papaipi kuti muwongolere bwino chitoliro ndi mpope.Pakakhala kupanikizika koyipa mu chitoliro, valavu imatha kuyamwa mwachangu mumlengalenga kuti iteteze kuwonongeka komwe kumachitika chifukwa cha kupanikizika koyipa.
Pampu yamadzi ikasiya kugwira ntchito, kupanikizika koyipa kumapangidwa nthawi iliyonse.Kuyandama kumagwa nthawi iliyonse.M'malo otopa, buoy imakokera pansi mbali imodzi ya lever chifukwa cha mphamvu yokoka.Panthawiyi, lever ili m'malo olowera, ndipo pali kusiyana pakati pa gawo la lever ndi dzenje lotulutsa mpweya.
Mpweya umatulutsidwa ndi dzenje lolowera kudzera mumpata uwu.Ndi kutuluka kwa mpweya, mlingo wa madzi umakwera ndipo buoy imayandama mmwamba pansi pa kuthamanga kwa madzi.Mapeto osindikizira pa lever pang'onopang'ono amakanikizira dzenje lakumtunda mpaka dzenje lonselo litatsekedwa kwathunthu ndipo valavu yotulutsa mpweya itatsekedwa kwathunthu.

Njira zodzitetezera pakukhazikitsa valavu yotulutsa mpweya:
1.Valve yotulutsa mpweya iyenera kuyikidwa molunjika, ndiko kuti, iyenera kuonetsetsa kuti buoy yamkati ili pamtunda, kuti isakhudze kutuluka.
2. Pamene avalavu yotulutsa mpweyawaikidwa, ndi bwino kukhazikitsa ndi valavu kugawa, kuti pamenevalavu yotulutsa mpweyaiyenera kuchotsedwa kuti ikonzedwe, ikhoza kuonetsetsa kuti kusindikizidwa kwa dongosololi ndipo madzi samatuluka.
3.Thevalavu yotulutsa mpweyanthawi zambiri imayikidwa pamalo apamwamba kwambiri a dongosolo, zomwe zimathandiza kuti mpweya uziyenda bwino.
Ntchito yavalavu yotulutsa mpweyamakamaka kuchotsa mpweya mkati mwa payipi.Chifukwa nthawi zambiri pamakhala mpweya wosungunuka m'madzi, ndipo kusungunuka kwa mpweya kumachepa ndi kuwonjezeka kwa kutentha, kotero m'kati mwa kayendedwe ka madzi gasi pang'onopang'ono analekanitsidwa ndi madzi, ndipo pang'onopang'ono anasonkhana pamodzi kuti apange thovu lalikulu kapena ngakhale mpweya. Mzere, chifukwa cha madzi owonjezera, choncho nthawi zambiri pamakhala kupanga gasi.
Nthawi zambiri amagwiritsidwa ntchito pamakina otenthetsera odziyimira pawokha, makina otenthetsera apakati, boiler yotenthetsera, mpweya wapakati, kutentha kwapansi ndi makina otenthetsera a solar ndi utsi wina wamapaipi.

Zofunikira pakugwira ntchito kwa valve yotulutsa mpweya:
1.Thevalavu yotulutsa mpweyaiyenera kukhala ndi voliyumu yayikulu yotulutsa, ndipo chitoliro chopanda kanthu cha payipicho chikadzadza ndi madzi, imatha kuzindikira kutulutsa mwachangu ndikubwezeretsanso madzi abwinobwino munthawi yochepa kwambiri.
2. Pamene avalavu yotulutsa mpweyaali ndi kupanikizika koipa mu chitoliro, pisitoni iyenera kutsegula mofulumira ndikupuma mpweya wambiri wakunja mwamsanga kuti payipi isawonongeke ndi kupanikizika koipa.Ndipo pansi pa kukakamizidwa kugwira ntchito, mpweya wotsatizana womwe wasonkhanitsidwa mu payipi ukhoza kutulutsidwa.
3.Thevalavu yotulutsa mpweyakuyenera kukhala ndi mpweya wotseka wokwera kwambiri.Pakanthawi kochepa pisitoni isanatsekedwe, iyenera kukhala ndi mphamvu zokwanira zotulutsa mpweya mupaipi ndikuwongolera njira yoperekera madzi.
4.The madzi kutseka kuthamanga kwavalavu yotulutsa mpweyasayenera kukhala wamkulu kuposa 0.02 MPa, ndivalavu yotulutsa mpweyaakhoza kutsekedwa pansi pa kuthamanga kwa madzi otsika kuti asawononge madzi ambiri.
5.Valve yotulutsa mpweyaziyenera kupangidwa ndi chitsulo chosapanga dzimbiri choyandama mpira (chidebe choyandama) ngati magawo otsegulira ndi kutseka.
6.Thupi la valve yotulutsa mpweya liyenera kukhala ndi anti-impact chitetezo chamkati chamkati kuti chiteteze kuwonongeka msanga kwa mpira woyandama (chidebe choyandama) chifukwa cha kukhudzidwa kwachindunji kwa madzi othamanga kwambiri pa mpira woyandama ( ndowa yoyandama ) pambuyo pa kutha kwakukulu.
7.Kwa DN≥100valavu yotulutsa mpweya, kugawanika kwapangidwe kumatengedwa, komwe kumapangidwa ndi chiwerengero chachikulu chavalavu yotulutsa mpweyandivalavu yotulutsa mpweya yokhakukwaniritsa zofunikira za kuthamanga kwa mapaipi.Thevalavu yotulutsa mpweya yokhaAyenera kutengera njira yachiwiri ya lever kuti akulitse kwambiri kusuntha kwa mpira woyandama, ndipo madzi otseka amakhala otsika.Zonyansa zomwe zili m'madzi sizili zophweka kuti zigwirizane ndi malo osindikizira, ndipo doko lotulutsa mpweya silidzatsekedwa, ndipo ntchito yake yotsutsa-blocking ikhoza kusintha kwambiri.
Panthawi imodzimodziyo, pansi pa kupanikizika kwakukulu, chifukwa cha mphamvu ya lever ya pawiri, choyandamacho chimatha kutsika mofanana ndi mlingo wa madzi, ndipo mbali zotsegula ndi zotseka sizidzayamwa ndi kuthamanga kwakukulu monga ma valve achikhalidwe, kuti athe kutulutsa nthawi zonse. .
8. Pazikhalidwe zothamanga kwambiri, kuyambira pafupipafupi kwa mpope wamadzi ndi m'mimba mwake DN≧100, valavu ya pulagi ya buffer iyenera kuyikidwa pavalavu yotulutsa mpweyakuti muchepetse mphamvu ya madzi.Valavu ya plug ya Buffer iyenera kuteteza madzi ochulukirapo popanda kuwononga kuchuluka kwa utsi, kuti mphamvu yoperekera madzi isakhudzidwe, ndikuteteza bwino kuti nyundo yamadzi isachitike.
