Pa nthawi yokonza, ma valve a gulugufe wamba ndi amitundu iwiri: mtundu wa wafer ndi mtundu wa flange. Potseguka kwathunthu, makulidwe a mbale ya gulugufe ndiye okhawo omwe amaletsa kuti cholumikiziracho chiziyenda m'thupi la valavu, kotero kutsika kwa kuthamanga komwe kumachitika ndi valavu ndi kochepa, ndipo kumakhala ndi makhalidwe abwino owongolera kuyenda kwa madzi. Ngati vuto lapezeka, siyani kugwiritsa ntchito nthawi yomweyo ndikupeza chomwe chayambitsa.

Valavu ya mpira:

Mukasunga kwa nthawi yayitali, onetsetsani kuti malekezero onse awiri atsekedwa ndipo ali otseguka. Sungani oyera mukamagwiritsa ntchito ndipo onjezerani mafuta ku ulusi wotumizira nthawi zonse. Nthawi yomweyo, pewani kugwiritsa ntchito ngati otseguka pang'ono kuti mupewe kukhudzidwa ndi madzi pa valavu.

Pa nthawi yokonza, valavu ya mpira imatha kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu. Sizololedwa kugwiritsidwa ntchito kusintha kayendedwe ka madzi kuti zisakokoloke komanso kuti pamwamba pake pasamawonongeke mwachangu.
Kuphatikiza apo, pali malingaliro ena okhudza kusamalira ndi kukonza ma valve oyesera:

Valavu yofufuzira iyenera kusungidwa m'chipinda chouma komanso chopanda mpweya kuti zinyalala zisalowe mkati mwake ndikuwononga; mipata ya njira kumapeto onse awiri iyenera kutsekedwa ndi mutu kuti isunge magwiridwe antchito ake otseka.

Ma valve oyesera omwe akhala akusungidwa kwa nthawi yayitali ayenera kuunikidwa nthawi zonse, dothi lomwe lili mkati mwake liyenera kuchotsedwa, ndipo batala liyenera kuyikidwa mofanana pamalo okonzedwa kuti atetezedwe.

Momwe valavu yoyezera ikugwira ntchito iyeneranso kufufuzidwa nthawi zonse kuti izindikire ndikuchotsa zolakwika zazing'ono pakapita nthawi. Ngati vuto lalikulu lachitika, liyenera kuchotsedwa kuti likonzedwe. Pambuyo poyang'anira ndi kukonza, mayeso otseka ayenera kuchitidwanso, ndipo vuto ndi njira yowunikira ndi kukonza ziyenera kulembedwa mwatsatanetsatane.

Pa valavu yoyang'anira muffler, panthawi yosungira ndi kunyamula, magawo otsegulira ndi otseka ayenera kutsimikizika kuti ali otsekedwa, ndipo njira zotsatirazi ziyenera kutengedwa kuti zitetezedwe:

Diski ya valve iyenera kukhazikika pamalo otseguka.

Gwiritsani ntchito matabwa a thovu kuti mutseke mipata yamkati kumapeto onse awiri a dayamita ndipo muwamangirire mwamphamvu ndi zophimba zobisika kuti mupewe fumbi ndi dzimbiri, pamene mukusunga njira yoyera komanso kumapeto kwake kukhala kosalala.

Pakani bwino ndikuteteza gawo la silinda kuti liziteteza kugwedezeka ndi kugundana.

Ikayikidwa, iyenera kukhala yokhazikika, onetsetsani kuti chipangizo choyendetsera mpweya chikuyang'ana mmwamba, ndipo pewani kukanikizana.

Zikayikidwa kwa nthawi yayitali, dothi ndi dzimbiri pa njira ziwirizi ndi pamwamba pa chotseka komanso chitetezo cha doko lolumikizira ziyenera kufufuzidwa miyezi itatu iliyonse. Mukachotsa dothi ndi dzimbiri, mafuta oletsa dzimbiri ayenera kugwiritsidwanso ntchito kuti atetezedwe.

Ntchito yaikulu ya valavu yoyezera ndikuletsa kuti cholumikiziracho chisabwerere m'mbuyo, kotero chiyenera kuyikidwa kwambiri pazida, zida ndi mapaipi. Mavalavu oyezera choletsa nthawi zambiri amakhala oyenera zolumikizira zoyera ndipo sayenera kugwiritsidwa ntchito pazolumikizira zokhala ndi tinthu tolimba komanso kukhuthala kwakukulu. Pa mapaipi opingasa okhala ndi mainchesi 50mm, ndi bwino kugwiritsa ntchito mavalavu oyezera choletsa choyima.

Pofuna kupewa kuti valavu isachite dzimbiri, njira ziyenera kutengedwa monga kuyika mafuta oletsa dzimbiri kapena mafuta pamwamba pa thupi la valavu, makamaka pamalo ozizira. Nthawi yomweyo, nthawi zonse onani ngati zomangira za valavu zili zomasuka ndikuzilimbitsa pakapita nthawi. Zisindikizo ndi zinthu zofunika kwambiri kuti zitsimikizire kuti mavalavu akugwira ntchito bwino ndipo ziyenera kusinthidwa nthawi zonse. Nthawi zambiri amalangizidwa kuti azisinthidwa zaka 1-2 zilizonse, ndipo zisindikizo zomwe zikugwirizana ndi chitsanzo cha valavu ziyenera kusankhidwa posintha.

Kukonza:

Zolakwika ndi mayankho ofala ndi awa:

Disiki ya valavu yasweka: Izi nthawi zambiri zimachitika chifukwa cha kupanikizika kwapakati valavu yoyezera isanayambe komanso itatha kukhala pafupi ndi kulinganiza bwino komanso "kusefa" wina ndi mnzake, zomwe zimapangitsa kuti valavu yoyezera imenyedwe pafupipafupi. Kuti mupewe vutoli, tikukulimbikitsani kugwiritsa ntchito valavu yoyezera yokhala ndi valavu yopangidwa ndi zinthu zolimba.
