Valavu ya chipata ndi valavu yomwe chiwalo chotseka (chipata) chimayenda molunjika pakati pa msewu. Valavu ya chipata ingagwiritsidwe ntchito kokha potseka kwathunthu komanso motseka bwino mupaipi, ndipo singagwiritsidwe ntchito pokonza ndi kuponda. Valavu ya chipata ndi mtundu wa valavu yomwe imagwiritsidwa ntchito mosiyanasiyana. Nthawi zambiri, zida zodulira za DN50 zimasankhidwa kuti zigwiritsidwe ntchito, ndipo nthawi zina mavavu a chipata amagwiritsidwanso ntchito pazida zodulira zokhala ndi mainchesi ang'onoang'ono. Valavu ya chipata imagwiritsidwa ntchito ngati chodulira, ndipo kuyenda konse kumakhala kolunjika ikatsegulidwa kwathunthu. Pakadali pano, kutayika kwa mphamvu kwa chodulira kumakhala kochepa. Mavavu a chipata nthawi zambiri amakhala oyenera kugwira ntchito zomwe sizifunika kutsegulidwa ndi kutsekedwa pafupipafupi ndikusunga chipata chotseguka kwathunthu kapena chotsekedwa kwathunthu. Sikoyenera kugwiritsidwa ntchito ngati malamulo kapena kuponda. Pa chodulira champhamvu chothamanga, chipata chingayambitse kugwedezeka kwa chipata chikatsegulidwa pang'ono, ndipo kugwedezeka kungawononge malo otsekera chipata ndi mpando wa valavu, ndipo kuponda kudzapangitsa kuti chipata chiwonongeke ndi chodulira.
Kuchokera ku kapangidwe kake, kusiyana kwakukulu ndi mawonekedwe a chinthu chotsekera chomwe chimagwiritsidwa ntchito. Malinga ndi mawonekedwe a zinthu zotsekera, ma valve a zipata nthawi zambiri amagawidwa m'mitundu yosiyanasiyana, monga: valavu ya chipata cha wedge, valavu ya chipata chofanana, valavu ya chipata chofanana, valavu ya chipata chofanana, ndi zina zotero. Mitundu yomwe imagwiritsidwa ntchito kwambiri ndi ma valve a chipata cha wedge ndi ma valve a chipata chofanana.
Chipata chili ndi malo awiri otsekera. Malo awiri otsekera a valavu ya chipata cha wedge yomwe imagwiritsidwa ntchito kwambiri amapanga wedge. Ngodya ya wedge imasiyana malinga ndi magawo a valavu, nthawi zambiri madigiri 5. Chipata cha valavu ya chipata cha wedge chingapangidwe kukhala chonse, chotchedwa chipata cholimba; chingapangidwenso kukhala chipata chomwe chingapangitse kusintha pang'ono kuti chiwongolere kupanga kwake ndikupangitsa kuti ngodya ya pamwamba pa sealing isinthe pang'ono panthawi yokonza. Mbaleyi imatchedwa chipata chotanuka.
Vavu ya chipata ikatsekedwa, pamwamba pake potsekeredwa pamafunika mphamvu yapakati kuti itseke, kutanthauza kuti, kudalira mphamvu yapakati kuti ikanikize pamwamba pake potsekeredwa pa mpando wa valavu womwe uli mbali inayo kuti zitsimikizire kuti pamwamba pake potsekeredwa patsekedwa, komwe kumadzitsekereza wekha. Mavavu ambiri a chipata amagwiritsa ntchito kutsekeredwa kokakamizidwa, kutanthauza kuti, valavu ikatsekedwa, chipatacho chiyenera kukakamizidwa motsutsana ndi mpando ndi mphamvu yakunja kuti zitsimikizire kuti pamwamba pake potsekeredwa patsekedwa pakhazikika.
Valavu ya chipata cha valavu ya chipata imayenda molunjika ndi tsinde la valavu, lomwe limatchedwa valavu ya chipata cha tsinde lokweza (lomwe limatchedwanso valavu ya chipata chokwera). Nthawi zambiri pamakhala ulusi wa trapezoidal pa ndodo yokweza, kudzera mu nati pamwamba pa valavu ndi mng'alu wotsogolera pa thupi la valavu, kayendedwe kozungulira kamasinthidwa kukhala kayendedwe kolunjika, ndiko kuti, mphamvu yogwirira ntchito imasinthidwa kukhala mphamvu yogwirira ntchito.
Valavu ikatsegulidwa, pamene kutalika kwa chipata kuli kofanana ndi nthawi 1:1 ya kukula kwa valavu, njira yamadzimadzi imatsegulidwa kwathunthu, koma malo awa sangayang'aniridwe panthawi yogwira ntchito. Pakugwiritsa ntchito kwenikweni, nsonga ya tsinde la valavu imagwiritsidwa ntchito ngati chizindikiro, ndiko kuti, malo omwe sangatsegulidwe, ngati malo ake otseguka kwathunthu. Pofuna kuganizira za kutsekeka komwe kumachitika chifukwa cha kusintha kwa kutentha, nthawi zambiri imatsegulidwa pamalo apamwamba, kenako nkubwerera 1/2 ~ 1, ngati malo a valavu yotseguka kwathunthu. Chifukwa chake, malo otseguka kwathunthu a valavu amatsimikiziridwa ndi malo a chipata (ndiko kuti, kukwapula).
Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.
