Uma usangabaza ukuthi ukhetha amavalvu esango lensimbi efojiwe noma amavalufu esango ensimbi (WCB), sicela upheqa ifekthri ye-zfa valve ukuze wethule umehluko omkhulu phakathi kwawo.

1. Ukuqamba nokuphonsa izindlela ezimbili ezihlukene zokucubungula.

Ukubunjwa: Insimbi iyashisisa bese iyancibilika bese ithelwa esikhunjeni sesihlabathi noma isikhunta.Ngemva kokupholisa, iqina ibe into.Izimbobo zomoya zikhiqizwa kalula phakathi komkhiqizo.
Forging: Ikakhulukazi kusetshenziswa izindlela ezifana nokushaya ngesando emazingeni okushisa aphezulu ukwenza insimbi ibe ucezu lokusebenza olunomumo nosayizi othile esimweni sepulasitiki, futhi uguqule izici zayo ezibonakalayo.

2. Umehluko ekusebenzeni phakathi kwamavalvu esango akhiwe kanyeAma-valve esango le-WCB

Ngesikhathi sokubumba, insimbi idlula i-plastic deformation, enomthelela wokuhlanza okusanhlamvu, ngakho-ke ivame ukusetshenziswa ekukhiqizeni okungenalutho kwezingxenye ezibalulekile.Ukusakaza kunezidingo ezintweni okufanele zicutshungulwe.Ngokuvamile, insimbi ekhonjiwe, i-aluminium, njll. inezici zokuphonsa ezingcono.I-Casting ayinazo izinzuzo eziningi zokufoja, kodwa ingakwazi ukwenza izingxenye ezinomumo oyinkimbinkimbi, ngakho-ke kuvame ukusetshenziswa ekukhiqizeni okungenalutho kwezingxenye zokusekela ezingadingi izakhiwo eziphakeme zemishini.

2.1 Ingcindezi

Ngenxa yomehluko wezakhiwo ezibonakalayo, ama-valve ensimbi akhiwe angakwazi ukumelana namandla amakhulu, futhi ipulasitiki yawo, ukuqina kanye nezinye izakhiwo zemishini ziphakeme kunalezoAma-valve e-WCB.Ngakho-ke, ingasetshenziswa ezimweni ezicindezelayo eziphezulu zokusebenza.Amazinga okucindezela asetshenziswa ngokuvamile ama-valve ensimbi akhiwe yilawa: PN100;I-PN160;I-PN250;I-PN320;I-PN400, 1000LB~4500LB.Izingcindezi ezivame ukusetshenziswa zamavalvu e-WCB yilezi: PN16, PN25, PN40, 150LB~800LB.

2.2 Ububanzi Nominal

Ngenxa yokuthi inqubo yokubumba inezidingo eziphezulu ezikhunjini nasezinsizeni, ububanzi bamavalvu omgunyathi ngokuvamile bungaphansi kwe-DN50.

2.3 Amandla okumelana nokuvuza

Kunqunywa inqubo ngokwayo, ukusakaza kujwayele ukukhiqiza i-blowhole ngesikhathi sokucubungula.Ngakho-ke, uma kuqhathaniswa nenqubo yokubumba, ikhono lokuvimbela ukuvuza kwamavalvu ajikijelwayo alilungile njengalawo amavalvu omgunyathi.
Ngakho-ke, kwezinye izimboni ezinezidingo eziphakeme zokuvimbela ukuvuza, njengegesi, igesi yemvelo, i-petroleum, amakhemikhali nezinye izimboni, ama-valve ensimbi akhiwe asetshenziswe kabanzi.

2.4 Ukubukeka

Amavalvu e-WCB namavalvu ensimbi akhiwe kulula ukuwahlukanisa ngokubukeka.Ngokuvamile, ama-valve e-WCB anombala osiliva, kuyilapho amavalvu ensimbi enziwe mbumbulu abonakala emnyama.

3. Umehluko emikhakheni yezicelo

Ukukhethwa okuqondile kwama-valve e-WCB namavalve ensimbi akhiwe kuncike endaweni yokusebenza.Akunakwenziwa ngokujwayelekile ukuthi yiziphi izinkambu ezisebenzisa amavalvu ensimbi akhiwe futhi yiziphi izinkambu ezisebenzisa amavalvu e-WCB.Ukukhetha kufanele kusekelwe endaweni ethile yokusebenza.Ngokuvamile, amavalvu e-WCB awakwazi ukumelana ne-asidi ne-alkali futhi angasetshenziswa kuphela kumapayipi avamile, kuyilapho amavalvu ensimbi enziwe ngomgunyathi akwazi ukumelana nokucindezela okukhulu futhi angasetshenziswa kwezinye izimboni ezinokushisa okuphezulu, njengezitshalo zikagesi nezitshalo zamakhemikhali.I-valve yekilasi.

4. Inani

Ngokuvamile, intengo yamavalvu ensimbi eyenziwe ngomgunyathi iphakeme kunaleyo yamavalvu e-WCB.
