Njira zophatikizira ma valve

Pali njira zitatu zodziwika bwino zopangira ma valve, zomwe ndi, njira yosinthira kwathunthu, njira yosinthira pang'ono, kukonza njira.

Njira yosinthirana kwathunthu

Pamene valavu imasonkhanitsidwa ndi njira yosinthira kwathunthu, gawo lililonse la valve likhoza kusonkhanitsidwa popanda kukonzanso ndi kusankha, ndipo mankhwalawa akhoza kukwaniritsa zofunikira zaumisiri pambuyo pa msonkhano. Panthawiyi, zigawo za valve ziyenera kukonzedwa mokwanira ndi zofunikira za mapangidwe kuti zikwaniritse zofunikira za kulondola kwazithunzi ndi kulekerera kwa geometric. Ubwino wa njira yathunthu yosinthira ndi: ntchito yolumikizirana ndiyosavuta komanso yotsika mtengo, ntchito sifunikira luso lapamwamba, kupanga bwino kwa msonkhano ndikwambiri, ndipo ndikosavuta kukonza mzere wa msonkhano ndi kupanga akatswiri. . Komabe, kunena mwamtheradi, pamene msonkhano wathunthu m'malo umatengedwa, kulondola kwa makina kumafunika kukhala apamwamba. Ndizoyenera valavu yapadziko lonse lapansi, valavu yoyendera, valavu ya mpira ndi ma valve ena okhala ndi mawonekedwe osavuta komanso awiri ang'onoang'ono ndi apakatikati.

Njira yosinthira pang'ono

Valavu imasonkhanitsidwa ndi njira yochepa yosinthira, ndipo makina onse amatha kukonzedwa molingana ndi kulondola kwachuma. Posonkhanitsa, kukula kwinakwake ndi kusintha ndi kubwezera kungasankhidwe kuti mukwaniritse kulondola kwa msonkhano. Mfundo ya njira yosankhidwa ndi yofanana ndi yokonza njira, koma njira yosinthira kukula kwa mphete yamalipiro ndi yosiyana. Yoyamba ndiyo kusintha kukula kwa mphete yamalipiro posankha zowonjezera, pamene chotsatira ndicho kusintha kukula kwa mphete yamalipiro mwa kudula zipangizo. Mwachitsanzo: pachimake pamwamba ndi kusintha gasket wa valavu ulamuliro valavu awiri nkhosa mphero chipata valavu, ndi kusintha gasket pakati pa matupi awiri a kugawanika mpira valavu, etc., ndi kusankha mbali zapadera monga mbali chipukuta misozi mu dimension unyolo zokhudzana kulondola kwa msonkhano, ndikukwaniritsa kulondola kwa msonkhano wofunikira posintha makulidwe a gasket. Pofuna kuonetsetsa kuti mbali zolipirira zokhazikika zitha kusankhidwa munthawi zosiyanasiyana, ndikofunikira kupanga zida zolipirira mawotchi ochapira ndi shaft ndi makulidwe osiyanasiyana ndi kukula kwake pasadakhale kusankha kwa hydraulic control valve pamisonkhano.

Kukonza njira

Valavu imasonkhanitsidwa ndi njira yokonza, zigawozo zikhoza kukonzedwa molingana ndi ndondomeko ya zachuma, ndiyeno kukula kwinakwake ndi kusintha ndi kubwezera malipiro kungakonzedwe panthawi ya msonkhano, kuti akwaniritse cholinga cha msonkhano. Mwachitsanzo, chipata ndi valavu thupi la wedge chipata valavu, chifukwa cha mkulu processing mtengo kukwaniritsa zofunika kusinthanitsa, ambiri opanga amatengera njira kukonza. Izi zikutanthauza kuti, pomaliza pogaya pachipata chosindikizira pachipata kuti athe kuwongolera kukula kotsegulira, mbaleyo iyenera kufananizidwa molingana ndi kukula kwa ma valve osindikizira a thupi, kuti akwaniritse zofunikira zosindikizira. Njirayi imawonjezera njira yofananira ndi mbale, koma imathandizira kwambiri zofunikira zolondola zomwe zidachitika kale. Kugwira ntchito mwaluso kwa njira yofananira mbale ndi antchito apadera sikungakhudze luso lopanga lonse. Njira yolumikizira ma valve: ma valve amasonkhanitsidwa payekhapayekha pamalo okhazikika. Kusonkhana kwa zigawo ndi zigawo ndi kusonkhana kwa ma valve kumachitidwa mu msonkhano wa msonkhano, ndipo mbali zonse zofunika ndi zigawo zimatumizidwa ku malo a msonkhano. Kawirikawiri, ndi magulu angati a ogwira ntchito omwe ali ndi udindo pa msonkhano wa zigawo ndi Msonkhano Wachigawo panthawi imodzi, zomwe sizimafupikitsa msonkhanowo, komanso zimathandizira kugwiritsa ntchito zida zapadera, ndipo zimakhala ndi zofunikira zochepa pa luso lamakono. ogwira ntchito.
