Kudzera mu kusanthula kwa mfundo ya kapangidwe ka valavu yokhazikika ya m'mapaipi, adapeza kuti mfundo yotsekera ndi yofanana, pogwiritsa ntchito mfundo ya "piston effect", ndipo kapangidwe kotsekera kokha ndi kosiyana.
Valavu pogwiritsira ntchito vutoli imawonekera makamaka m'madigiri osiyanasiyana, mitundu yosiyanasiyana ya kutayikira, malinga ndi mfundo ya kapangidwe kosindikiza ndi kukhazikitsa ndi kusanthula kwa khalidwe la zomangamanga, zomwe zimayambitsa kutayikira kwa vavu ndi izi:
1. Kukhazikitsa ma valavu ndi ubwino wa zomangamanga ndiye chifukwa chachikulu
Pakukhazikitsa, kapangidwe kake sikalabadira chitetezo cha pamwamba pa valavu yotsekera ndi mphete ya mpando yotsekera, kuwonongeka kwa pamwamba pa kutsekera; kukhazikitsa kwatha, kuphulika kwa mapaipi ndi valavu sikunamalizidwe, sikuli koyera, pakugwira ntchito pali slag kapena miyala yowotcherera yomwe yamatirira pakati pa mpira ndi mphete ya mpando yotsekera, zomwe zimapangitsa kuti kutsekera kulephereke. Pankhaniyi, pakagwa ngozi, pamwamba pa kutsekera pamwamba pa mtsinje kuyenera kubayidwa kwakanthawi ndi kuchuluka koyenera kwa sealant kuti kuchepetse kutuluka kwa madzi, koma sikungathe kuthetsa vutoli kwathunthu, ngati kuli kofunikira, pamwamba pa kutsekera valavu ndi mphete ya mpando yotsekera ziyenera kusinthidwa.
2. Kukonza makina a valavu, kusindikiza mphete, ndi zifukwa zabwino zosonkhanitsira
Ngakhale kapangidwe ka valavu ndi kosavuta, ndi kofunikira kwambiri pazinthu zabwino zokonzera makina, khalidwe lake lokonza limakhudza mwachindunji magwiridwe antchito otsekera. Mphete ya mpando wotseka ndi mipando ya mphete ziyenera kuwerengedwa molondola, kuuma kwa pamwamba pa mphete kuyenera kukhala koyenera. Kuphatikiza apo, kusankha zinthu zofewa zotsekera ndikofunikira kwambiri, osati kungoganizira za dzimbiri ndi kukana kuvala komanso kuganizira kulimba kwake. Ngati ndi yofewa kwambiri, idzakhudza luso lodziyeretsa lokha; ngati ndi yolimba kwambiri, idzakhala yosavuta kusweka.
3. Kusankha koyenera malinga ndi momwe ntchito ikuyendera komanso momwe zinthu zilili
Machitidwe osiyanasiyana otsekera ndi kapangidwe kotsekera ka valavu pogwiritsa ntchito zochitika zosiyanasiyana, nthawi zosiyana zokha kuti musankhe valavu yosiyana, kuti mupeze zotsatira zabwino zogwiritsira ntchito. Mwachitsanzo, pankhani ya payipi ya gasi ya West-East, mavalavu okhazikika a payipi okhala ndi kutsekera mbali ziwiri ayenera kusankhidwa momwe angathere (kupatula mavalavu a payipi ozungulira okhala ndi kutsekera kokakamizidwa, omwe ndi okwera mtengo kwambiri). Mwanjira imeneyi, ngati chisindikizo chakumtunda chawonongeka, chisindikizo chakumunsi chikhoza kugwirabe ntchito. Valavu yotsekera yokakamizidwa iyenera kusankhidwa ngati pakufunika kudalirika kwathunthu.
4. Pa ma valve okhala ndi mawonekedwe osiyanasiyana otsekera, njira zosiyanasiyana zogwirira ntchito, kukonza, ndi kukonza ziyenera kugwiritsidwa ntchito.
Pa ma valve omwe alibe kutuluka madzi, valavu ikhoza kudzazidwa ndi mafuta pang'ono isanayambe komanso itatha ntchito iliyonse kapena miyezi 6 iliyonse pang'ono pa tsinde ndi ma poti olowetsa sealant, ndipo pokhapokha ngati kutuluka madzi kwachitika kapena sikungathe kutsekedwa kwathunthu ndi pomwe kuchuluka koyenera kwa sealant kumayikidwa. Chifukwa cha kukhuthala kwakukulu kwa sealant, ngati valavu nthawi zambiri sidzadzazidwa ndi sealant, idzakhudza momwe pamwamba pake pamadzi ...
