1. I-medium yokusebenza

Ngokwezindlela ezahlukene zokusebenza, kuyadingeka ukukhetha izinto ezinokumelana nokugqwala okuhle. Isibonelo, uma into ephakathi ingamanzi anosawoti noma amanzi olwandle, idiski ye-valve yethusi ye-aluminium ingakhethwa; Uma into ephakathi i-asidi enamandla noma i-alkali, i-tetrafluoroethylene noma i-fluororubber ekhethekile ingakhethwa njengezinto zesihlalo se-valve.

2. Ingcindezi yokusebenza kanye nokushisa

i-valve yebhabhathane yophawu lwerabhakudingeka zisebenze ngokujwayelekile ngaphakathi kwengcindezi yokusebenza echaziwe kanye nobubanzi bokushisa, ngakho-ke kuyadingeka ukukhetha izinto ezinamandla anele kanye nokumelana nokushisa.

3. Izimo zemvelo

Cabanga ngezimo zemvelo lapho ivalvu itholakala khona, njengomswakama, isifutho sikasawoti, njll., bese ukhetha izinto ezifanele. 

4. Izinto zomzimba we-valve

Izinto zomzimba we-valveivalvu yebhabhathane yeflangekufaka phakathi insimbi empunga ephothiwe, insimbi ephothiwe, insimbi ephothiwe, insimbi engagqwali, njll. Phakathi kwazo, insimbi engagqwali inokusebenza okuhle kakhulu, kodwa izindleko ziphezulu kakhulu. Uma isendaweni enomfutho ophansi, ukusebenza kwezinto zensimbi eziphothiwe kungaqhathaniswa nokwezinto zensimbi eziphothiwe, futhi izindleko zokusebenzisa izinto zensimbi eziphothiwe ziphansi.

5. Izinto zesihlalo se-valve

Izinto zokuhlala ze-i-worm gear butterfly valvezifaka irabha kanye ne-fluoroplastics. Izihlalo zamavalvu erabha zingasetshenziswa ezindaweni ezibuthakathaka njenge-asidi kanye ne-alkaline njengamanzi, umusi, kanye namafutha, futhi zisebenza kahle ekuvaleni; Izihlalo zamavalvu e-Fluoroplastic zisetshenziswa ezindaweni ezibola kakhulu.

6. Izinto zediski yebhabhathane

Izinto zediski yebhabhathane zamavalvu ebhabhathane asetshenziswa ngesandla zifaka phakathi insimbi ethambile kanye nensimbi engagqwali. Ngezinye izikhathi, ukuze uzivumelanise nezimo zemidiya eziyinkimbinkimbi, kuyadingeka ukugoqa idiski yebhabhathane ngeglue noma ngezinto ze-PTFE.

7. Izinto zomgodi we-valve

Iningi lazo lenziwe ngensimbi engagqwali, futhi izimo ezikhethekile zingenziwa ngokwezifiso ngokwezidingo.

8. Izinto zokushayela

Kunezindlela ezimbili eziyinhloko zokusebenza ngesandla, isibambo kanye negiya lezibungu. Izinto zokubamba zifaka phakathi insimbi ephothiwe, insimbi yekhabhoni, insimbi engagqwali, i-aluminium alloy, njll.; Izinto zekhanda legiya lezibungu ikakhulukazi ziyinsimbi ephothiwe.

Ngamafuphi, ukukhethwa kwekhwalithi yezinto ezibonakalayoivalvu yebhabhathane elenziwe ngesandlakufanele icabangele ngokuphelele izici ezifana nendawo yokusebenza, ingcindezi yokusebenza kanye nokushisa, izimo zemvelo, kanye nezinto zokwakha umzimba we-valve, isihlalo se-valve, i-butterfly disc, kanye nomgodi we-valve. Ukukhetha izinto ezifanele kungaqinisekisa ukusebenza okuvamile kanye nokuphila kwenkonzo ye-valve.ivalvu yebhabhathane lamanzi.
