Ingabe ulwela ukukhetha i-valve efanele yephrojekthi yakho? Ingabe ukhathazwa yizinhlobonhlobo eziningi zamamodeli nama-brand emakethe? Kuzo zonke izinhlobo zamaphrojekthi wobunjiniyela, ukukhetha i-valve efanele kubaluleke kakhulu. Kodwa imakethe igcwele ama-valve. Ngakho-ke sihlanganise umhlahlandlela wokukusiza kalula nangobuhlakanikhetha umkhiqizo we-valve ofanele wena. Kungakhathaliseki ukuthi udinga ukulawulwa kokugeleza, ukulawulwa kwengcindezi noma ukunqanyulwa koketshezi, sinamathiphu namasu esingakusiza. Thatha isinyathelo sokuzethemba ngokusebenzisa le maze yamavalvu futhi ujabulele izindleko nokonga isikhathi ngenkathi usebenza kuphrojekthi yobunjiniyela ephumelelayo.

1.Khomba inhloso yevalvu emshinini noma ocingweni

Thola izimo zokusebenza ze-valve: uhlobo lwe-medium esebenzayo, ingcindezi yokusebenza, izinga lokushisa lokusebenza kanye nemodi yokulawula.

2.Khetha uhlobo lwevalvu olufanele

Ukukhetha okulungile kohlobo lwe-valve kusekelwe ekuqondeni okugcwele komklami kwayo yonke inqubo yokukhiqiza nezimo zokusebenza njengemfuneko, ekukhetheni uhlobo lwevalvu, umklami kufanele aqale abe yingcweti yezimpawu zesakhiwo nokusebenza kwevalvu ngayinye.

3.Thola ukuxhumana kokuphela kwe-valve

Ekuxhumekeni okunentambo, ukuxhumana kwe-flange, nokuxhumana okuhlanganisiwe ekugcineni, okubili kokuqala kusetshenziswa kakhulu. Ama-valve anemicu ama-valve ikakhulukazi anobubanzi obuncane obungaphansi kuka-50mm, uma ubukhulu bobubanzi bukhulu kakhulu, ukufakwa nokuvala ingxenye yokuxhuma kunzima kakhulu. I-valve exhunyiwe ye-Flange, ukufakwa kwayo nokuhlakazeka kulula kakhulu, kodwa i-valve exhunywe kakhulu enentambo inkulu, intengo iphakeme, ngakho ifaneleka ububanzi obuhlukahlukene kanye nokucindezela kokuxhuma kwepayipi. Uxhumano oluhlanganisiwe lufanele izimo eziphakeme zokusika umthwalo futhi luthembeke kakhulu kunoxhumano lwe-flange. Kodwa-ke, ukuqaqa nokufakwa kabusha kwama-valve ashiselwe kunzima kakhulu, ngakho-ke ukusetshenziswa kwawo kunqunyelwe ezikhathini lapho ngokuvamile kungasebenza khona ngokwethembeka isikhathi eside, noma lapho izimo zokusetshenziswa kuwukuqoshwa futhi izinga lokushisa liphezulu.

4.Ukukhethwa kwempahla yeValve

Ukukhethwa kwegobolondo le-valve, izingxenye zangaphakathi nezinto ezingaphezulu zokuvala uphawu, ngaphezu kokucabangela izici ezibonakalayo zendawo yokusebenza (izinga lokushisa, ingcindezi) kanye nezakhiwo zamakhemikhali (ukugqwala), kufanele futhi zilawule ukuhlanzeka kwendawo ephakathi (azikho izinhlayiya eziqinile. ), ngaphezu kwalokho, kodwa futhi abhekisele ezinhlinzekweni ezifanele zombuso kanye nokusetshenziswa komnyango. Ukukhethwa okulungile nokunengqondo kwezinto ze-valve kungathola impilo yesevisi eyonga kakhulu kanye nokusebenza okungcono kakhulu kwe-valve. Ukulandelana kokukhethwa kwezinto zomzimba we-valve yilezi: insimbi ecijile - i-carbon steel - insimbi engagqwali, kanye nokulandelana kokukhethwa kwezinto zokuvala indandatho yile: irabha - ithusi - i-alloy steel -F4.

5.okunye

Ukwengeza, izinga lokugeleza kanye nezinga lokucindezela koketshezi olugeleza nge-valve kufanele kunqunywe, futhi i-valve efanele kufanele ikhethwe kusetshenziswa ulwazi olutholakalayo (njengekhathalogi yomkhiqizo we-valve, amasampula omkhiqizo we-valve, njll.). 

 I-JinbinValveingumkhiqizi ozibophezele ekuhlinzekeni amavalvu ekhwalithi ephezulu, futhi imikhiqizo yawo ithunyelwa emazweni amaningi aseNingizimu-mpumalanga ye-Asia naseMelika. Xhumana nathi manje futhi usivumele senze ngokwezifiso isixazululo se-valve esingcono kakhulu kuwe!
