Njira zodzitetezera zofunika pakuyika ma valve

Poika valavu, pofuna kuteteza zitsulo, mchenga ndi zinthu zina zakunja kuti zilowe mu valve ndikuwononga malo osindikizira, fyuluta ndi valve yothamanga iyenera kuikidwa;kuti mpweya woponderezedwa ukhale woyera, olekanitsa madzi a mafuta kapena fyuluta ya mpweya ayenera kuikidwa kutsogolo kwa valve.
 
Poganizira kuti momwe ntchito ya valve ikuyendera ikhoza kufufuzidwa panthawi yogwira ntchito, ndikofunikira kukhazikitsa zida ndifufuzani ma valve;kuti musunge kutentha kwa ntchito, ikani malo osungira kutentha kunja kwa valve.
 
Pakuyika pambuyo pa valavu, valavu yotetezera kapena valve yowunikira iyenera kuikidwa;poganizira ntchito yosalekeza ya valavu, yomwe ili yabwino pangozi, dongosolo lofanana kapena njira yodutsa imakhazikitsidwa.
 
Yang'anirani chitetezo cha valve
 
Pofuna kupewa kutayikira kwa valve yoyang'ana kapena kubwereranso kwa sing'anga pambuyo polephera, zomwe zingayambitse kuwonongeka kwa khalidwe la mankhwala ndi kuyambitsa ngozi ndi zotsatira zina zosafunika, ma valve amodzi kapena awiri otseka amaikidwa pamaso ndi pambuyo pake.Ngati ma valve awiri otseka aperekedwa, valavu yoyang'ana ikhoza kusokonezeka mosavuta ndikukonzedwa.
 
Malo otetezedwa a valve chitetezo
 
Ma valve otsekera nthawi zambiri samayikidwa isanayambe kapena itatha njira yokhazikitsira, ndipo angagwiritsidwe ntchito pazochitika payekha.Ngati mphamvu yapakati imakhala ndi tinthu tating'onoting'ono ndipo imakhudza kuti valavu yachitetezo sichikhoza kutsekedwa mwamphamvu mutachoka, valavu yachipata yokhala ndi chisindikizo chotsogolera iyenera kuikidwa isanayambe komanso itatha.Vavu yachipata iyenera kukhala yotseguka kwathunthu.DN20 yang'anani valavu kupita kumlengalenga.
 
Sera ikatuluka ndi zoulutsira zina zili zolimba kutentha kwa firiji, kapena kutentha kwamadzi opepuka ndi zowulutsa zina ndi zotsika kuposa madigiri 0 Celsius chifukwa cha kuchepa kwamphamvu kwa mpweya, valavu yachitetezo imafunika kutsata nthunzi.Kwa mavavu otetezera omwe amagwiritsidwa ntchito muzofalitsa zowononga, kutengera kukana kwa dzimbiri kwa valavu, ganizirani kuwonjezera filimu yosaphulika yosaphulika polowera valavu.
 
Valavu yotetezera gasi nthawi zambiri imakhala ndi valavu yodutsa molingana ndi mainchesi ake polowera pamanja.
 
Malo oteteza ma valve ochepetsa mphamvu
 
Nthawi zambiri pali mitundu itatu ya ma valve ochepetsera kuthamanga.Miyezo yamagetsi imayikidwa isanayambe komanso itatha valavu yochepetsera mphamvu kuti athe kuyang'anitsitsa kupanikizika musanayambe ndi pambuyo pake.Palinso valavu yotetezedwa yotsekedwa kumbuyo kwa valve kuti iteteze kupanikizika pambuyo poti valavu idumphire pamene kupanikizika kumbuyo kwa valve kumadutsa kupanikizika kwachibadwa pambuyo poti valavu yochepetsetsa ikulephera, kuphatikizapo dongosolo kumbuyo kwa valve.

Chitoliro chokhetsa chimayikidwa kutsogolo kwa valavu yotsekera kutsogolo kwa valve, yomwe imagwiritsidwa ntchito makamaka kutulutsa mtsinje wa ngalande, ndipo ena amagwiritsa ntchito misampha.Ntchito yaikulu ya chitoliro chodutsa ndi kutseka ma valve otsekera musanayambe komanso pambuyo pa valavu yochepetsera kupanikizika pamene valavu yochepetsera kupanikizika ikulephera, kutsegula valavu yodutsa, kusintha kayendetsedwe kake pamanja, ndikugwira ntchito yozungulira kwakanthawi, kuti akonze valavu yochepetsera kupanikizika kapena kusintha valavu yochepetsera.
 
Magawo a chitetezo chamthupi
 
Pali mitundu iwiri ya chitoliro chodutsa ndipo palibe chitoliro cholambalala pambali pa msampha.Pali kubwezeretsedwa kwa madzi a condensate ndi kubweza kwa condensate osabweza, ndipo mphamvu ya ngalande ya misampha ndi zofunika zina zapadera zitha kukhazikitsidwa mofanana.
 
Msampha wokhala ndi valavu yodutsa umagwiritsidwa ntchito makamaka kutulutsa kuchuluka kwa condensate pamene payipi iyamba kuyenda.Pokonza msampha, sikoyenera kugwiritsa ntchito chitoliro chodutsa kuti mukhetse condensate, chifukwa izi zidzachititsa kuti nthunzi ituluke m'madzi obwerera.
 
Muzochitika zachilendo, chitoliro chodutsa sichifunika.Pokhapokha pakakhala zofunikira kwambiri pa kutentha kwa kutentha, zida zowotchera zopangira mosalekeza zimakhala ndi chitoliro chodutsa.
