3, valavu ya mpira: yapangidwa kuchokera ku valavu yolumikizira, ziwalo zake zotsegulira ndi kutseka ndi mpira, pogwiritsa ntchito mpirawo mozungulira tsinde la kuzungulira 90° kuti cholinga chotsegulira ndi kutseka chikwaniritsidwe. Vavu ya mpira imagwiritsidwa ntchito makamaka kudula, kugawa ndikusintha njira ya kayendedwe kapakati mu payipi. Vavu ya mpira yokhala ndi kutseguka kofanana ndi v ilinso ndi ntchito yabwino yolamulira kayendedwe ka madzi.
Ubwino:
(1) Ndi kukana kwa madzi pang'ono (kwenikweni 0);
② Popeza sichidzagwira ntchito (ngati palibe mafuta), chingagwiritsidwe ntchito moyenera pa zinthu zowononga komanso pamadzimadzi otsika kutentha;
Pakupanikizika ndi kutentha kosiyanasiyana, imatha kutseka kwathunthu;
④ Imatha kutsegula ndi kutseka mwachangu, ndipo nthawi yotsegulira ndi kutseka ya nyumba zina ndi masekondi 0.05-0.1 okha kuti iwonetsetse kuti ingagwiritsidwe ntchito mu dongosolo lodziyimira payokha la bedi loyesera. Kutsegula ndi kutseka mwachangu kwa valavu, kugwira ntchito popanda kukhudza;
(5) Zigawo zotsekera zozungulira zimatha kuyikidwa zokha pamalo olowera malire;
⑥ Chogwirira ntchito mbali zonse ziwiri za chisindikizo ndi chodalirika;
⑦ Ikatsegulidwa bwino komanso kutsekedwa bwino, pamwamba pa mpira ndi mpando pamakhala patali ndi sing'anga, kotero sing'anga kudzera mu valavu yothamanga kwambiri sidzayambitsa kuwonongeka kwa pamwamba pa sing'anga;
⑧ kapangidwe kakang'ono, kolemera pang'ono, kakhoza kuonedwa ngati kapangidwe koyenera ka valavu yamakina otsika kutentha;
⑨ Thupi la valavu yofanana, makamaka kapangidwe ka thupi la valavu yolumikizidwa, limatha kupirira kupsinjika kuchokera ku chitsime cha mapaipi;
⑩ Zigawo zotseka zimatha kupirira kusiyana kwa kuthamanga kwambiri zikatsekedwa. (11) Thupi lolumikizira ma valve a mpira, likhoza kuikidwa mwachindunji pansi, kuti ziwalo zamkati za valavu zisawonongeke, nthawi yayitali yogwira ntchito mpaka zaka 30, ndiye valavu yoyenera kwambiri pamapaipi amafuta ndi gasi wachilengedwe.
Zoyipa:
(1) Popeza mphete yotsekera mpando waukulu wa valavu ndi ptfe, siigwira ntchito ndi mankhwala onse, ndipo ili ndi makhalidwe onse a friction coefficient yaying'ono, magwiridwe antchito okhazikika, osakalamba mosavuta, kutentha kosiyanasiyana komanso magwiridwe antchito abwino kwambiri otsekera. Koma makhalidwe enieni a PTFE, kuphatikizapo friction coefficient yayikulu, kukhudzidwa ndi kuyenda kozizira komanso kutentha koipa, amafuna kuti seal ya mpando ipangidwe mozungulira makhalidwe awa. Zotsatira zake, pamene sealing ilimba, kudalirika kwa seal kumawonongeka. Kuphatikiza apo, kukana kutentha kwa PTFE kumakhala kochepa ndipo kungagwiritsidwe ntchito pokhapokha ngati kutentha kuli pansi pa 180℃. Kupitirira kutentha kumeneku, sealing tool idzakalamba. Ngati igwiritsidwa ntchito kwa nthawi yayitali, nthawi zambiri siigwiritsidwa ntchito pa 120℃.
② Kugwira ntchito kwake kowongolera n'koipa kuposa valavu yozungulira, makamaka valavu yozungulira mpweya (kapena valavu yamagetsi).

Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.

Zinthu zazikulu:Valavu ya Gulugufe,Valavu ya Mpira,Valavu ya Chipata,Valavu Yowunikira,Globe Vavlve,Zipangizo za Y,Chotsukira Magetsi,Zipangizo zoyezera mpweya (Pneumatic Acurators).
