Chifukwa cha mkangano wochepa pakati pa malo osindikizira panthawi yotsegulira ndi kutseka, valve yotseka imakhala yokhazikika ndipo imakhala ndi kutalika kochepa kotsegula.Sikoyenera kokha kwapakatikati ndi kutsika kwapakati, komanso koyenera kwa media media.Kudalira kupanikizika kwa tsinde la valve, malo osindikizira a diski ndi malo osindikizira a mpando wa valve amamangiriridwa kwambiri kuti ateteze sing'angayo kuti isayende, yomwe ndi valve yokakamiza yosindikiza.Kuti mugwirizane ndi kagwiritsidwe ntchito ka zochitika zosiyanasiyana, pali mitundu inayi ya ma valve otseka omwe ali ndi ntchito zosiyanasiyana: valavu yotsekera yotsekera, valavu yotsekera molunjika, valavu yotseka yamba ndi valavu yotseka.Kodi pali kusiyana kotani pakati pawo?
1) Kulowetsa ndi kutulutsa kwa valve yoyimitsa yamtundu wa ngodya kuli pamakona a madigiri 90.Valavu yoyimitsa ngodya nthawi zambiri imayikidwa pakona ya payipi ndipo imatha kulowetsa chitoliro pakona.
Mu valavu yotsekera yamtundu wa ngodya, madzimadzi amangofunika kusintha njira yake kamodzi, kotero kuti kuthamanga kutsika kudzera mu valve kumakhala kochepa kusiyana ndi valavu yachizolowezi yotseka.
2) Mawonekedwe apangidwe ndi luso losankhira valavu yoyimitsa molunjika, valavu yoyimitsa molunjika, valavu yoyimitsa ngodya ndi valavu ya plunger ndi valavu ya Y-mtundu woyimitsa.Ndi ngodya ya madigiri a 45, mlingo wa kuwonongeka kwa kayendedwe ka kayendedwe kake ndi kakang'ono kuposa kamene kamakhala kotseka ma valve, kotero kutayika kwa mphamvu kudzera mu valve kumakhala kochepa.Zitha kunenedwanso kuti palibe kutayika kwa kutsika kwamphamvu, komanso kutayika kochepa kwambiri kwa ma valve onse otseka..
3) Valavu yamtundu wa Plunger: Mtundu uwu wa valavu yapadziko lonse lapansi ndikusintha kwa valavu yapadziko lonse lapansi.Mu valavu iyi, mpando wa disc ndi valve nthawi zambiri umapangidwa kutengera mfundo ya plunger.Chovala cha valve chimapukutidwa kuti plunger ndi tsinde la valve zilumikizidwe, ndipo kusindikiza kumatheka ndi mphete ziwiri zosindikizira zokhala ndi manja pa plunger.Mphete ziwiri zosindikizira zotanuka zimasiyanitsidwa ndi mphete ya manja, ndipo mphete yosindikizira mozungulira plunger imakanikizidwa mwamphamvu ndi katundu woperekedwa pa bonati ndi mtedza wa boneti.Mphete yosindikiza zotanuka imatha kusinthidwa ndipo imatha kupangidwa ndi zinthu zosiyanasiyana.Valavu imagwiritsidwa ntchito makamaka "kutsegula" kapena "kutseka", koma ili ndi mawonekedwe apadera a plunger kapena kolala yapadera.Kuthamanga kwapampando wapawiri wa valve molunjika-kupyolera mu valavu ya plunger.Plunger imatha kusunthira mmwamba ndi pansi mu mphete zosindikizira zakumwamba ndi zapansi ndi dzanja lowongolera.Bowo lowongolera limaperekedwa ndi bowo lotsekera, ndipo kuthamanga kwapakati kumatha kulowa m'munsi mwa bowo lowongolera kudzera pabowo laling'ono.Kusindikiza kungathe kupezedwa ndi kusindikiza kawiri pamwamba pa plunger ndi mphete yosindikizira iwiri mu thupi la valve, ndipo kutuluka kwakukulu kungathe kudutsa.Chifukwa plunger ndi yaifupi, liwiro lotsegula ndi kutseka ndilokwera kuposa la valve ya plunger wamba;valavu ya plunger imayenda molunjika, Plunger imakhala yopanda kanthu, ndipo zipinda zam'mwamba ndi zapansi zimadutsa mabowo.Tsinde la valavu limalumikizidwa ndi manja osindikizira apamwamba komanso nati kuti azitha kupanikizika m'zipinda zam'mwamba ndi zam'munsi za plunger ndikusunga khama potsegula ndi kutseka.Komabe, tsinde la valve liyenera kukhala ndi chisindikizo chapamwamba ndi chisindikizo chonyamulira, ndipo kutsegula ndi kutseka kufulumira.

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