Mukayika valavu yachipata, pofuna kuteteza zinthu zakunja monga zitsulo ndi mchenga kuti zisalowe mu valve yachipata ndikuwononga malo osindikizira;m'pofunika kukhazikitsa fyuluta ndi valavu yotulutsa.Kuti mpweya woponderezedwa ukhale woyera, cholekanitsa madzi a mafuta kapena fyuluta ya mpweya iyenera kuikidwa pamaso pa valve yachipata.Poganizira kuti ntchito yogwira ntchito ya valve ya pakhomo ikhoza kuyang'aniridwa panthawi yogwira ntchito, m'pofunika kukhazikitsa zida ndi kufufuza ma valve.
Wopanga valavu yachipata adanena kuti pofuna kusunga kutentha kwa ntchito, zipangizo zotetezera kutentha zimayikidwa kunja kwa valve yachipata;pakuyika kumbuyo kwa valve, valavu yotetezera kapena valavu yowunikira iyenera kukhazikitsidwa;poganizira ntchito yosalekeza ya valve yachipata, yomwe ili yabwino komanso yoopsa, dongosolo lofanana kapena njira yodutsa imakhazikitsidwa.
1. Yang'anani malo otetezedwa a valve pachipata:
Ma valve amodzi kapena awiri otseka amaikidwa musanayambe ndi pambuyo pake kuti ateteze kuwonongeka kwa khalidwe la mankhwala, ngozi ndi zotsatira zina zoipa zomwe zimachitika chifukwa cha kutayikira kapena kubweza kwapakati pambuyo poti cheke chalephera.Valve yowunikira imatha kuchotsedwa mosavuta ndikutumikiridwa ngati ma valve awiri otseka aperekedwa.
2. Kukhazikitsa chitetezo cha valve chitetezo
Valavu yotseka nthawi zambiri siyimayikidwa isanayambe komanso itatha njira yoyika, ndipo ingagwiritsidwe ntchito pazochitika payekha.Akumbutseni aliyense kuti ngati mphamvu yapakati ili ndi tinthu tating'onoting'ono, idzakhudza valavu yachitetezo kuti isatsekedwe pambuyo ponyamuka.Choncho, valve yotsekedwa ndi chipata iyenera kukhazikitsidwa isanayambe komanso itatha.Ma valve a zipata ndi chitetezo ayenera kutsegulidwa kwathunthu ndipo valavu yowunikira ya DN20 yopita kumlengalenga iyenera kuyikidwa mwachindunji.Opanga ma valve a zipata
Wopanga valavu pachipata ananena kuti pa kutentha wabwinobwino, pamene sing'anga monga sera pang'onopang'ono kumasulidwa ndi olimba, kapena pamene gasification kutentha madzi kuwala ndi sing'anga zina ndi otsika kuposa 0 chifukwa decompression, kufufuza nthunzi chofunika.Ngati ndi valavu yotetezera yomwe imagwiritsidwa ntchito pazitsulo zowonongeka, ndiye kuti malinga ndi kukana kwa dzimbiri kwa valve yachipata, m'pofunika kuwonjezera filimu yoteteza kuphulika kwa khomo la chipata.Nthawi zambiri, ma valve otetezera gasi amakhala ndi valavu yodutsamo polowera pamanja kutengera kukula kwake.
3. Malo otetezedwa a valve yochepetsera kuthamanga:
Nthawi zambiri pamakhala mitundu itatu yoyika zida zochepetsera ma valve.Zoyezera zokakamiza zimayikidwa musanayambe komanso pambuyo pa valavu yochepetsera, yomwe ndi yabwino kuyang'ana kupanikizika musanayambe ndi pambuyo pake.Ikani valavu yotetezedwa yotsekedwa kwathunthu kumbuyo kwa valve yachipata kuti muteteze kulephera kwa valve yachipata.Pamene kupanikizika kumbuyo kwa valve kumadutsa kupanikizika kwachibadwa, dongosolo la kumbuyo kwa valve limalumpha.Opanga ma valve a zipata
Chitoliro chokhetsa chimayikidwa kutsogolo kwa valavu yotseka kutsogolo kwa valavu yachipata, ndipo imagwiritsidwa ntchito makamaka poyendetsa ngalande.Ena a iwo amagwiritsa ntchito misampha ya nthunzi.Chitoliro chodutsa chimagwiritsidwa ntchito makamaka kutseka valavu yotsekera, kutsegula valavu yodutsa, ndikusintha pamanja kayendedwe kamene isanayambe komanso itatha kulephera kwa valve kuchepetsa kuthamanga.Ikhoza kuyendetsedwa panjinga ndiyeno valavu yothandizira kukonzedwa kapena kusinthidwa.
4. Malo otetezera misampha ya nthunzi:
Wopanga ma valve a pachipata ananena kuti pali mitundu iwiri ya misampha yokhala ndi mapaipi odutsa komanso opanda, kuphatikiza misampha yokhala ndi zofunikira zapadera monga kuchira kwa condensate, kubweza kwa condensate, komanso chindapusa cha ngalande.Ikhoza kukhazikitsidwa mofanana.Akatswiri athu amakukumbutsani kuti pokonza misampha, musakhetse ma condensate kudzera panjira yodutsa, zomwe zimalola nthunzi kutuluka ndikubwerera kumadzi.Munthawi yanthawi zonse, palibe chifukwa choyika chitoliro chodutsa, ndipo ndichoyenera kupangira zida zotenthetsera zomwe zimafunikira kutentha kwambiri pakuwotcha kosalekeza.
