Kufotokozera kwazinthu za valve yoyandama:
Valavu yoyandama imatengera mfundo ya lever, kudzera mu mulingo wamadzi pa mpira woyandama, kuzindikira valavu ya mpira woyandama yotseguka ndi kutseka.Choyandamacho chimayandama pamadzi nthawi zonse, ndipo madzi akamakwera, choyandamacho chimayandamanso.Pamene choyandama chikukwera, ulalo umakwera mmwamba.Chitsulo chosapanga dzimbiri choyandama valavu cholumikizira ndodo chimalumikizidwa ndi valavu kumapeto kwina.Ikakwezedwa pamalo enaake, ndodoyo imachirikiza pisitoni ya rabara kuti isindikize madzi.Madzi akatsika, choyandamacho chimatsikanso, ndipo chowuma chimayendetsanso pisitoni kuti chitseguke.

 

Mfundo yogwiritsira ntchito valavu yoyandama:
Thupi loyandama la valve limatenga ukadaulo woponya zitsulo zosapanga dzimbiri, kuti gawo lililonse lifanane bwino, palibe dzimbiri lotayirira kapena lokhazikika, kuwonetsetsa kuti valavu ya mpira imagwira ntchito mokhazikika kwa nthawi yayitali, pomwe gawo lachitsulo chosapanga dzimbiri limapanga. valavu ya mpira imagwira ntchito m'malo achinyezi kwambiri popanda kuwononga mankhwala, kuti madzi akumwa akhale oyera komanso athanzi.
Poona chilema kuti zoyandama mpira wa mankhwala chikhalidwe n'zosavuta kuvala ndi kusweka, mankhwala ntchito mpira kuwira luso kuthana ndi zoyandama mpira mkati mwa thupi, kuti athetse kufooka kuti zoyandama mpira amalephera chifukwa cha kuwonongeka. ndikutulutsa mpweya, ndikukulitsa moyo wautumiki wa mpira woyandama mpaka katatu.

Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
