Kufunika
Mavavu amagwira ntchito yofunika kwambiri m'mafakitale kuyambira pamafuta ndi gasi kupita ku mapaipi ndi makina otenthetsera. Zida zing'onozing'onozi zimayang'anira kayendedwe ka madzi ndi mpweya, kuonetsetsa kuti zikugwira ntchito bwino ndi chitetezo. Komabe, ma valve nthawi zina amakhala ovuta kufika kapena kugwira ntchito chifukwa cha malo kapena mapangidwe awo. Pankhaniyi, akuwonjezera valvezimabwera mumasewera. M'nkhaniyi, tiwona kufunikira kwa zowonjezera ma valve, mitundu yawo yosiyanasiyana, ndi ntchito zawo m'mafakitale osiyanasiyana.
Zowonjezera ma valve ndi chida chamtengo wapatali chomwe chimapangitsa kuti zikhale zosavuta kugwiritsa ntchito ndikusunga ma valve m'malo ovuta kufika. Amakulitsa chogwirira cha valve kapena makina owongolera, kulola kuti igwiritsidwe ntchito ndikuyang'aniridwa patali. Zowonjezera ma valve nthawi zambiri zimagwiritsidwa ntchito pomwe valavu imayikidwa pansi, kumbuyo kwa chotchinga, kapena kugwira ntchito pansi pa kutentha kwakukulu, kupanikizika, kapena zoopsa.
Mtundu
Pali mitundu yosiyanasiyana ya ma valve owonjezera pamsika masiku ano. Mtundu umodzi wotchuka ndi kufalikira kwa tsinde la valavu, komwe nthawi zambiri amagwiritsidwa ntchito pa ma valve omwe ali m'maenje akuya kapena okwiriridwa pansi. Izizowonjezeranthawi zambiri amapangidwa kuchokera kuzinthu zolimba monga chitsulo chosapanga dzimbiri kapena mkuwa kuti zipirire zovuta zachilengedwe. Amapereka mgwirizano wamphamvu pakati pa tsinde la valve ndi chogwirira ntchito pamwamba pa nthaka kuti zigwire ntchito mosavuta ndi kuwongolera.
Mtundu wina wowonjezera valavu ndi chowongola dzanja. Zowonjezerazi zimagwiritsidwa ntchito kukulitsa kufikira kapena kutalika kwa gudumu lamanja, kulola kugwira ntchito bwino kwa ma valve omwe ali m'malo otsekeka kapena patali kwambiri. Amagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala a madzi, kupanga magetsi ndi kukonza mankhwala, kumene ma valve awa akhoza kuikidwa m'madera osafikirika.
Kuphatikiza pa tsinde ndi magudumu owonjezera pamanja, palinso zowonjezera za lever, zabwino kwa ma valve omwe amafunikira kupalasa njinga pafupipafupi kapena amakhala m'malo owopsa. Zowonjezera za lever zimapereka mkono wotalikirapo wowonjezera wowonjezera komanso kugwira ntchito bwino. Amatha kukhazikitsidwa mwachangu ndikuchotsedwa pakafunika, kuwapanga kukhala njira yosunthika pamafakitale osiyanasiyana.
Kugwiritsa
Zowonjezera ma valve zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Mwachitsanzo, mu gawo la mafuta ndi gasi, zowonjezera ma valve zimagwiritsidwa ntchito pa ma valve omwe ali kutali ndi madera akutali kapena kumtunda. Zowonjezera izi zimathandiza ogwira ntchito kuwongolera kutuluka kwa zakumwa kapena mpweya, kuwonetsetsa kuti mapaipi kapena malo opangira zinthu zikuyenda bwino komanso moyenera. Momwemonso, m'makampani amadzi ndi madzi onyansa, ma valve owonjezera amapindulitsa ma valve omwe amaikidwa m'mabwalo apansi pansi, m'mabowo kapena m'zipinda zapansi pamadzi, zomwe zimapangitsa kuti zikhale zosavuta kuzisamalira ndi kukonza.
Zowonjezera ma valve zimagwiritsidwanso ntchito kwambiri pamakampani a HVAC (kuwotcha, mpweya wabwino ndi mpweya). Ma valve a HVAC nthawi zambiri amakhala m'malo ang'onoang'ono kapena ovuta, zomwe zimapangitsa kuti ntchito yawo ikhale yovuta. Mavavu owonjezera amathandizira izi pokulitsa kufikira kwa chogwirira cha valve kuti chisinthidwe ndi kuwongolera mosavuta. Zimathandizanso akatswiri kuti azikonza mwachizolowezi popanda kusokoneza dongosolo lonse.
Mapeto
Mwachidule, zowonjezera ma valve ndi chida chamtengo wapatali kwa mafakitale kumene ma valve ndi ovuta kupeza kapena kugwira ntchito. Amathandizira kukonza, kukonza ndi kugwiritsira ntchito ma valve m'malo ovuta kufikako mwa kukulitsa kufikira kwa chogwirira cha valve kapena makina owongolera. Mitundu yosiyanasiyana ya zowonjezera tsinde la valve, zowonjezera magudumu am'manja ndi zowonjezera za lever zilipo kuti apereke mayankho oyenera a mafakitale ndi ntchito zosiyanasiyana. Kaya mumafuta ndi gasi, mankhwala amadzi kapena HVAC, zowonjezera ma valve zimatsimikizira kugwira ntchito bwino komanso moyo wautali wa ma valve ovuta.
Zowonjezera ma valve zimagwiritsidwanso ntchito kwambiri pamakampani a HVAC (kuwotcha, mpweya wabwino ndi mpweya). Ma valve a HVAC nthawi zambiri amakhala m'malo ang'onoang'ono kapena ovuta, zomwe zimapangitsa kuti ntchito yawo ikhale yovuta. Mavavu owonjezera amathandizira izi pokulitsa kufikira kwa chogwirira cha valve kuti chisinthidwe ndi kuwongolera mosavuta. Zimathandizanso akatswiri kuti azikonza mwachizolowezi popanda kusokoneza dongosolo lonse.
