Uma usanqikaza ukuthi ukhetha ama-valve esango lensimbi enziwe ngobumba noma ama-valve esango lensimbi ecijile (i-WCB), sicela ubheke i-zfa valve factory ukuze wethule umehluko omkhulu phakathi kwawo.

1. Ukwakha nokusakaza kuyizindlela ezimbili ezahlukene zokucubungula.

Ukubumba: Insimbi iyashiswa bese incibilikiswa bese ithululelwa esikhumbeni sesihlabathi noma esikhumbeni. Ngemva kokupholisa, iyaqina ibe yinto ethile. Izimbobo zomoya zikhiqizwa kalula phakathi komkhiqizo.
Ukwakha: Ngokuyinhloko kusetshenziswa izindlela ezifana nokukhahlela emazingeni okushisa aphezulu ukuze kwenziwe insimbi ibe yinto yokusebenza enesimo nosayizi othile esimweni sepulasitiki, futhi kushintshwe izakhiwo zayo zomzimba.

2. Umehluko ekusebenzeni phakathi kwamavalvu esango ahlanganisiwe kanyeAmavalvu esango le-WCB

Ngesikhathi sokwakha, insimbi iguqulwa ngepulasitiki, okunomthelela wokucwenga okusanhlamvu, ngakho-ke ivame ukusetshenziswa ekukhiqizeni izingxenye ezibalulekile ezingenalutho. Ukwakha kunezidingo zezinto okufanele zicutshungulwe. Ngokuvamile, insimbi ecijile, i-aluminium, njll. inezakhiwo ezingcono zokukhiqiza. Ukwakha akunazo izinzuzo eziningi zokukhiqiza, kodwa kungakha izingxenye ezinezimo eziyinkimbinkimbi, ngakho-ke kuvame ukusetshenziswa ekukhiqizeni izingxenye ezingenalutho ezingadingi izakhiwo eziphezulu zemishini.

2.1 Ingcindezi

Ngenxa yokwehluka kwezakhiwo zezinto ezibonakalayo, amavalvu ensimbi akhiwe angamelana namandla amakhulu okushayisana, futhi ukuqina kwawo, ukuqina kanye nezinye izakhiwo zemishini ziphakeme kunezo ze-Amavalvu e-WCBNgakho-ke, ingasetshenziswa ezimweni zokusebenza ezicindezelayo eziphakeme. Amazinga okucindezela avame ukusetshenziswa amavalvu ensimbi ahlanganisiwe yilawa: PN100; PN160; PN250; PN320; PN400, 1000LB~4500LB. Izingcindezi ezivamile ezivame ukusetshenziswa zamavalvu e-WCB yilawa: PN16, PN25, PN40, 150LB~800LB.

2.2 Ububanzi Obuqanjiwe

Ngenxa yokuthi inqubo yokwakha inezidingo eziphezulu kuma-mold kanye nemishini, ububanzi bama-valve ahlanganisiwe buvame ukuba ngaphansi kwe-DN50.

2.3 Amandla okulwa nokuvuza

Uma kunqunywa inqubo ngokwayo, ukuphotha kuthambekele ekukhiqizeni imbobo yomoya ngesikhathi sokucubungula. Ngakho-ke, uma kuqhathaniswa nenqubo yokuphotha, ikhono lokuvimbela ukuvuza kwamavalvu aphothayo alilihle njengelamavalvu aphothayo.
Ngakho-ke, kwezinye izimboni ezinezidingo eziphezulu zokuvimbela ukuvuza, njengegesi, igesi yemvelo, uphethiloli, amakhemikhali kanye nezinye izimboni, amavalvu ensimbi ahlanganisiwe asetshenziswe kabanzi.

2.4 Ukubukeka

Amavalvu e-WCB namavalvu ensimbi ahlanganisiwe kulula ukuwahlukanisa ngokubukeka. Ngokuvamile, amavalvu e-WCB anokubukeka kwesiliva, kuyilapho amavalvu ensimbi ahlanganisiwe enokubukeka okumnyama.

3. Umehluko emasimini ohlelo lokusebenza

Ukukhethwa okuqondile kwama-valve e-WCB nama-valve ensimbi ahlanganisiwe kuncike endaweni yokusebenza. Akunakwenziwa kabanzi ukuthi yiziphi izinkambu ezisebenzisa ama-valve ensimbi ahlanganisiwe nokuthi yiziphi izinkambu ezisebenzisa ama-valve e-WCB. Ukukhethwa kufanele kusekelwe endaweni yokusebenza ethile. Ngokuvamile, ama-valve e-WCB awamelani ne-asidi ne-alkali futhi angasetshenziswa kuphela kumapayipi ajwayelekile, kuyilapho ama-valve ensimbi ahlanganisiwe angamelana nokucindezela okuphezulu futhi angasetshenziswa kwezinye izimboni ezinamazinga okushisa aphezulu, njengezitshalo zikagesi nezitshalo zamakhemikhali. I-valve yekilasi.

4. Intengo

Ngokuvamile, intengo yamavalvu ensimbi ehlanganisiwe iphakeme kuneyamavalvu e-WCB.
