Kusanthula kwazikulu zinayi zomwe zimayambitsa kutayikira kwa mavavu a mpira ndi njira zothana nazo

Kupyolera mu kusanthula kwa ndondomeko ya valavu ya payipi yokhazikika, anapeza kuti mfundo yosindikiza ndi yofanana, pogwiritsa ntchito mfundo ya "piston effect", ndipo mawonekedwe osindikizira okha ndi osiyana.

Vavu pakugwiritsa ntchito vutoli makamaka amawonetseredwa mu madigiri osiyanasiyana, mitundu yosiyanasiyana ya kutayikira, malinga ndi mfundo ya kusindikiza dongosolo ndi unsembe ndi kumanga khalidwe kusanthula, zomwe zimayambitsa kutayikira valavu ndi mbali zotsatirazi.

1. Kuyika ma valve ndi khalidwe la zomangamanga ndilo chifukwa chachikulu

Pomanga unsembe salabadira valavu kusindikiza pamwamba ndi kusindikiza mpando chitetezo mphete, kusindikiza pamwamba kuwonongeka;unsembe watsirizika, payipi ndi valavu kuwomba pabowo si wangwiro, osati woyera, pakugwira ntchito pali kuwotcherera slag kapena miyala inakanidwa pakati pa mpira ndi kusindikiza mphete mphete, kuchititsa kulephera kusindikiza.Pankhaniyi, mwadzidzidzi, pamwamba pa mtsinje wosindikiza kumtunda uyenera kuikidwa kwa kanthawi ndi kuchuluka kwa sealant kuti athetse kutayikira, koma sangathe kuthetsa vutoli, ngati kuli kofunikira, valavu yosindikizira pamwamba ndi mphete yosindikiza mpando iyenera kusinthidwa.

2. Vavu makina processing, kusindikiza mphete zakuthupi, ndi misonkhano khalidwe zifukwa

Ngakhale mawonekedwe a valve ndi osavuta, ndizofunikira kwambiri zamakina opangira zinthu zamakina, kukonza kwake kumakhudza mwachindunji ntchito yosindikiza.Tsekani mphete yapampando ndi chilolezo chapampando wapampando ndi malo aliwonse a mphete kuti awerengedwe molondola, makulidwe ake akhale oyenera.Kuonjezera apo, kusankha kwa zinthu zofewa zofewa ndizofunikanso kwambiri, osati kungoganizira zowonongeka ndi kuvala kukana komanso kuganizira za elasticity ndi kuuma kwake.Ngati ili yofewa kwambiri, idzakhudza luso lodziyeretsa;ngati ndizovuta kwambiri, zimakhala zosavuta kusweka.

3. Kusankhidwa koyenera malinga ndi ntchito ndi momwe ntchito zikuyendera

Zochita zosiyana zosindikizira ndi zomangira zosindikizira za valve pogwiritsa ntchito zochitika zosiyanasiyana, nthawi zosiyana zokha kusankha valavu yosiyana, kuti mupeze zotsatira zoyenera.Pankhani ya mapaipi a gasi a West-East, mwachitsanzo, ma valve opangidwa ndi mapaipi okhazikika okhala ndi kusindikiza kwa bi-directional ayenera kusankhidwa momwe angathere (kupatula ma valve a orbital omwe amasindikizidwa mokakamiza, omwe ndi okwera mtengo).Mwanjira iyi, ngati chisindikizo cha kumtunda chawonongeka, chisindikizo chakumtunda chikhoza kugwirabe ntchito.Valovu yosindikizidwa mokakamiza iyenera kusankhidwa ngati kudalirika kotheratu kumafunika.

4. Kwa ma valve okhala ndi masinthidwe osiyanasiyana osindikizira, njira zosiyanasiyana zogwirira ntchito, kukonza, ndi kutumizira ziyenera kugwiritsidwa ntchito.

Kwa ma valve omwe alibe kutayikira, valavu imatha kudzazidwa ndi mafuta isanayambe kapena itatha ntchito iliyonse kapena miyezi 6 iliyonse pazing'onozing'ono pamadoko a tsinde ndi sealant, ndipo pokhapokha ngati kutayikira kwachitika kapena sikungathe kusindikizidwa kwathunthu. kuchuluka koyenera kwa jekeseni wosindikizira.Chifukwa cha kukhuthala kwapamwamba kwa chosindikizira, ngati valavu sikhala yodzaza ndi sealant, idzakhudza kudziyeretsa kwa malo ozungulira, nthawi zambiri zotsutsana, kubweretsa grit yaing'ono ndi dothi lina pakati pa chisindikizo kuti chiwonongeko.Kwa ma valve omwe ali ndi chisindikizo cha njira ziwiri, ngati malo otetezedwa amaloleza, kupanikizika kwa valve patsekeke kuyenera kumasulidwa ku zero, kuti atsimikizire kusindikiza.
