Monga gawo lofunika kwambiri la makina opangira mafakitale, kuyika koyenera ndikofunikira. Valavu yoyikidwa bwino sikuti imangotsimikizira kuyenda bwino kwa madzi amakina, komanso imawonetsetsa kuti makinawo ndi otetezeka komanso odalirika. M'malo akuluakulu opangira mafakitale, kuyika mavavu sikutanthauza kungoganizira zaukadaulo, komanso kutsatira malamulo ndi miyezo yoyenera yachitetezo. Chifukwa chake, kufunika koyika mavavu moyenera sikungowonekera pakugwira bwino ntchito ndi kukhazikika kwa makinawo, komanso pachitetezo cha antchito ndi zida. Kudzera mu kuyika koyenera, mavuto otuluka amatha kuchepetsedwa, magwiridwe antchito a makina amatha kukonzedwa, ngozi zamafakitale zitha kupewedwa, chilengedwe ndi miyoyo ya antchito ndi katundu zitha kutetezedwa, motero kupereka chitetezo chodalirika pakupanga mafakitale. Chifukwa chake, kuyika mavavu moyenera ndikofunikira ndipo ndi chimodzi mwazinthu zofunika kwambiri pakuwonetsetsa kuti makina opangira mafakitale akugwira ntchito bwino.

1. Valavu yozungulira.

Zotsatira zake: valavu yozungulira, valavu yozungulira, valavu yochepetsera kupanikizika, valavu yowunikira ndi mavavu ena ali mbali imodzi, ngati yozungulira, valavu yozungulira imakhudza momwe imagwiritsidwira ntchito komanso moyo wake; Mavavu ochepetsa kupanikizika sagwira ntchito konse, ndipo mavavu owunikira amathanso kukhala pachiwopsezo.

Miyeso: Ma valve wamba, okhala ndi zizindikiro zoyendetsera thupi la valve; Ngati sichoncho, ayenera kuzindikirika bwino malinga ndi mfundo yogwirira ntchito ya valve. Chipinda cha valve cha globe valve sichili chofanana, ndipo madzi ayenera kuloledwa kudutsa mu doko la valve kuchokera pansi kupita pamwamba, kotero kuti kukana kwa madzi kumakhala kochepa (kutsimikiziridwa ndi mawonekedwe), kutsegulako kumapulumutsa ntchito (chifukwa cha kuthamanga kwapakati mmwamba), ndipo sing'anga sikakamiza kulongedza pambuyo potseka, zomwe zimakhala zosavuta kukonza. Ichi ndichifukwa chake valavu yoyimitsa singathe kusinthidwa. Musatembenuze valavu ya chipata (ndiko kuti, gudumu lamanja pansi), apo ayi sing'anga idzakhalabe pamalo ophimba valavu kwa nthawi yayitali, yosavuta kuwononga tsinde la valavu, ndipo ndi zoletsa pazofunikira zina. Ndikovuta kwambiri kusintha kulongedza nthawi yomweyo. Tsegulani valavu ya chipata cha tsinde, musayike pansi, apo ayi chifukwa cha chinyezi ndi dzimbiri zomwe zimawululidwa ndi tsinde la valavu. Kwezani valavu yowunikira, kuyika kuti muwonetsetse kuti valavu ya disc yoyimirira, kuti chokweza chikhale chosinthika. Valavu yowunikira yozungulira, kuyika kuti muwonetsetse kuti pini ili mulingo, kuti chizungulire chikhale chosinthika. Valavu yochepetsera kupanikizika iyenera kuyikidwa moyimirira pa chitoliro chopingasa, ndipo musapendekere mbali iliyonse.

2. Kuyika mavavu sikunachitike musanayang'anire bwino khalidwe lofunikira.

Zotsatira zake: Zingayambitse kuti makina osinthira magetsi asasinthe, atsekedwe momasuka komanso kutuluka kwa madzi (mpweya), zomwe zimapangitsa kuti pakhale kukonzanso, komanso kusokoneza madzi abwinobwino (mpweya).

Miyeso: Musanayike ma valavu, muyenera kuchita mayeso a mphamvu yokakamiza ndi kulimba. Mayesowa ayenera kuchitika poyesa 10% ya kuchuluka kwa gulu lililonse (kalasi yomweyo, mfundo zomwezo, chitsanzo chomwecho), ndipo osachepera chimodzi. Pa ma valavu otsekedwa omwe amayikidwa pa chitoliro chachikulu omwe amagwira ntchito yodula, mayeso a mphamvu ndi kulimba ayenera kuchitika chimodzi ndi chimodzi. Kuthamanga kwa mphamvu ndi kulimba kwa ma valavu kuyenera kutsatira malamulo ovomerezeka.

3. Flange ya valavu ya gulugufe yokhala ndi flange ya valavu wamba.

Zotsatira zake: kukula kwa flange ya valavu ya gulugufe ndi kosiyana ndi kukula kwa flange ya valavu wamba. Ma flange ena ali ndi mainchesi ang'onoang'ono amkati, ndipo flange ya valavu ya gulugufe ndi yayikulu, zomwe zimapangitsa kuti valavu isatsegulidwe kapena kutsegulidwa mwamphamvu.

Miyeso: Flange iyenera kukonzedwa malinga ndi kukula kwenikweni kwa flange ya valavu ya gulugufe.
