Muva nje, iqembu lezinto ezisetshenziswa ngesandla kanye nezikagesiamavalvu esango lommeseisiqede ngempumelelo ukulungisa amaphutha okuvula nokuvala ngokuphelele eshabhu futhi izolethwa kumaphrojekthi obunjiniyela baphesheya maduze. Imininingwane etholakalayo ihlanganisa i-DN150, i-DN200 kanye ne-DN300. Yaklanywa ngengcindezi encane ye-PN10, ama-valve agcina amazinga okushisa asebenza afinyelela ku-80°C futhi aklanyelwe ngokukhethekile indawo yamanzi ezinhlelweni zamapayipi.

I-valve yesango lommese inesakhiwo esincane kanye nendlela yokugeleza eqondile ephelele ngaphandle kwezindawo ezifile. Umzimba wayo wenziwe ngensimbi ethambile yezinga eliphezulu ngokusebenzisa ukuphonswa okunembile, okuletha ukuqina kwesakhiwo okuvelele kanye nokumelana nomthelela ngaphansi kwengcindezi yepayipi evamile. Ipuleti lesango lensimbi engagqwali linikeza ukumelana nokugqwala okuphezulu, okuqinisekisa i-torque ephansi yokusebenza ngesikhathi sokushintsha njalo. Umklamo wesihlalo esinwebekayo olungiselelwe kahle unikeza ukuvala okuqinile okuthembekile ukuze kugwenywe ukuvuza okuphakathi, kungakhathaliseki ukuthi kungaphansi kwengcindezi yokusebenza egcwele noma engaphelele.

Kunikezwa ukucushwa okubili kokusebenzisa amandla ukuze kwaneliswe izidingo ezahlukahlukene zesayithi. Inguqulo ebhalwe ngesandla ifakwe isondo lesandla elikhulisiwe, okuvumela ukusebenza okulula kwesayithi kwamapayipi amancane kanye neziteshi zokuhlola ezivamile. Inguqulo kagesi ingafakwa ama-actuator kagesi angaqhumi ukuze kufezwe ukulawula okuzenzakalelayo kokuvula nokuvala okukude.

Ukulawulwa kwekhwalithi kuhamba kuyo yonke imisebenzi yokukhiqiza. I-valve ngayinye ngayinye ihlolwa ngokuphindaphindiwe ngomjikelezo wokuvula nokuvala ngaphambi kokushiya ifektri. Ochwepheshe bethu bahlola ngokugcwele ukuguquguquka kokusebenza, ubuqotho bokuvala kanye nokuhlanganiswa kwezingxenye, basuse ngempumelelo amaphutha avamile njengokujama kwepuleti, ukuvuza kwangaphakathi kanye nokwehluleka kokusebenza ngesikhathi senkonzo eqhubekayo yesikhathi eside.

Uma kuqhathaniswa nama-valve esango avamile, ama-valve esango lommese anobukhulu bomzimba obuncane kakhulu, okunciphisa kakhulu isikhala sokufakwa esidingekayo futhi kufinyeze isikhathi sokwakha izinhlelo zamapayipi amasha nezivuselelwe. Isakhiwo sangaphakathi esilula sinciphisa ubunzima bokulungisa obujwayelekile; abaqhubi bangaqedela ukuhlolwa kwendawo kanye nokufakwa kwezingxenye ngaphandle kokudiliza i-valve yonke emapayipini, okunciphisa kakhulu izindleko zokusebenza zesikhathi eside kubanikazi bezimpahla.

Lolu chungechunge lwama-valve esango lommese lusebenzisa uxhumano olujwayelekile lwe-wafer lug, oluhambisana nezindinganiso ze-flange zamapayipi ezivamile emhlabeni jikelele, olulungele ukufakwa kwephrojekthi yomhlaba wonke. Asetshenziswa kabanzi ukuze alawulwe ngokusebenza kumanethiwekhi okuphakelwa kwamanzi kamasipala kanye nokuthuthwa kwamanzi, izikhungo zokuhlanza amanzi amdaka zasemadolobheni, izinhlelo zamanzi ajikelezayo ezimbonini, izikhungo zokujikeleza kwamanzi epaki kanye nobunjiniyela be-hydraulic engqalasizinda.

Sihlinzeka ngezinsizakalo zokwenza ngokwezifiso eziguquguqukayo kubalingani bomhlaba wonke. Ngaphandle kosayizi abajwayelekile be-DN150, DN200 kanye ne-DN300, singakwazi ukulungisa izinto zomzimba, izinto zokuvala kanye nezinhlobo ze-actuator ngokwezimo ezithile zokusebenza. Sigcina umthamo wokukhiqiza ozinzile, amazinga okuhlola aqinile kanye nokusekelwa okuphelele kwangemva kokuthengisa kwabakhi bobunjiniyela bomhlaba wonke, abahlanganisi bezinhlelo zokwelashwa kwamanzi kanye nabasabalalisi bamapayipi. Umgomo wethu ukuhlinzeka ngezixazululo zokulawula uketshezi ezizinzile nezingabizi kakhulu ezihambisana namaphrojekthi ahlukahlukene okwelashwa kwamanzi kanye nengqalasizinda kamasipala emhlabeni jikelele.
