Ivalvu yeButterfly yePTFE PFA Lining

I-ZFAIivalvu zebhabhathane ezine-fluorine, yenye yezonke iimvelisoyenziwe yi-ZFA VALVE. I-PTFE Lining Valve eyaziwa ngokuba ziivalvu ezimelana nokugqwala ezifakwe kwiplastiki ene-fluorine, ziiplastiki ezine-fluorine ezibunjwe eludongeni lwangaphakathi lweendawo ezithwala ivalvu yentsimbi okanye yesinyithi okanye umphezulu wangaphandle weendawo zangaphakathi zevalvu. Iiplastiki ezine-fluorine apha ziquka ikakhulu: i-PTFE, i-PFA, i-FEP kunye nezinye. I-FEP lined butterfly, i-teflon coated butterfly valve kunye ne-FEP lined butterfly valve zihlala zisetyenziswa kwiindawo ezinamandla zokugqwala.

 

Ivalvu yebhabhathane ene-fluorine yenye yezona mveliso ziphambili zeevalvu ze-ZFA. Uhlu lwethu luthathu lulandelayo:

1. Ngokwendlela umzimba wevalvu ocwangciswe ngayo, ungahlulwa ube luhlobo lwento enye kunye nohlobo lwento ezimbini.

2. Ngokwendlela i-lining ingahlulwahlulwa ibe yi-lined epheleleyo kunye ne-half-lined. I-butterfly valve e-lined epheleleyo yi-valve body kwaye i-valve plate igqunywe ngerabha; i-half-lining ibhekisa kuphela kwi-lining yomzimba we-valve.

3. Ngokweentlobo, iivalvu zebhabhathane ezineTeflon zingahlulwahlulwa zibeuhlobo lwe-wafer yevalvu yebhabhathane efakwe i-fluorine, ivalvu yebhabhathane ene-fluorine ene-lug kunye nevalvu yebhabhathane ene-fluorine ene-flange.

 

Iimpawu zevalvu yebhabhathane ene-fluorine:

1. I-PTFE/PFA/FEP ifakelwe imitya epheleleyo okanye eqhelekileyo.

2. Ivalvu yebhabhathane eneTeflon, ifanelekile kwisixhobo sekhemikhali esinobuthi nesinobuthi kakhulu.

3. Emva kokuvala uvavanyo lokhuseleko ngokuphindaphindiweyo, ivalvu yebhabhathane ehleli kwi-PTFE ayinangcoliseko kwindalo esingqongileyo.

4. Uyilo lwesakhiwo esiqhekekileyo esinokususwa. (Uyazikhethela)

5. Ubungakanani bokugquma buhambelana nemigaqo yezixhobo.

6. Ingafakwa nakweyiphi na indawo; Ayinalo ulondolozo kwaye inokuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza ezinzima.

7. Izinto ezisuswayo zingaphinda zisetyenziswe.

8. Le nto ihambelana nemigangatho ye-FDA.

9. Isenzo esinobuzaza kunye nokusebenza kakuhle kokutywina.

10. Isakhiwo silula kwaye sincinci, sibukeka sintle.

11. Izinto zokutywina azigugi kwaye azinakuguga, kwaye zihlala ixesha elide.
