Iivalvu zebhola zentsimbi ezenziweyozizinto ezisetyenziswa kakhulu kwiimveliso ezininzi zeevalvu. Ngenxa yokusebenza kwayo okugqwesileyo, isetyenziswa kakhulu kwiintlobo ngeentlobo zolwelo ezifana nomoya, amanzi, umphunga, izixhobo ezahlukeneyo zokubola, udaka, ioyile, isinyithi esilulwelo kunye nezixhobo ze-radioactive. Kodwa uyazi ukuba zeziphi izibonelelo zeevalvu zebhola zentsimbi ezibunjiweyo? Makhe ndikunike intshayelelo emfutshane.
1. Ukumelana okunamandla ne-vulcanization kunye nokuqhekeka. Izinto ezisetyenziswa kuyoivalvu yebhola yentsimbi eyenziweyoXa idibana nesixhobo kukho izinto zobugcisa obuphezulu, ezihambelana nenqanaba elisemgangathweni lamazwe ngamazwe. Umphezulu ugqunywe nge-nickel, onokuhlangabezana nokusebenza okuphezulu kwe-vulcanization.
2. Ivalvu yentsimbi eyenziweyo yenziwe ngezinto zepolymer okanye i-alloy, ezimelana nobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye zifanelekile ukudluliselwa kunye nokubhoboza izixhobo ezahlukeneyo. Ngaphezu koko, ngenxa yezinto ezikhethekileyo, inokumelana nokugqwala okunamandla, ihlala ixesha elide kwaye inoluhlu olubanzi lokusetyenziswa.
3. Ayisiyo kuphela ivalvu eyenziwe ngezinto ezimelana nokugqwala, kwanesihlalo sevalvu senziwe ngezinto ezikhethekileyo, kwaye le nto yi-PTFE engangeni khemikhali phantse kuzo zonke iikhemikhali, ngoko ke inokuhlala ivaliwe ixesha elide. Ngenxa yokungangeni kwayo, inamandla okusebenza, ayilungi lula ukuguga, kwaye ingasetyenziswa ixesha elide.
4. Ngokubanzi,ivalvu yebhola yentsimbi eyenziweyoilingana ngokulinganayo, ngoko ke inokumelana noxinzelelo olunamandla lombhobho, kwaye indawo yayo ayilula ukuyitshintsha. Isebenze kakuhle nokuba ivuliwe ngokupheleleyo okanye ivuliwe kancinci. Isebenza kakuhle ekuvaleni kwaye ayinamathele xa kuthuthwa ulwelo oluthambileyo.
Ezi zingentla zezinye zeempawu zeevalvu zentsimbi ezibunjiweyo. Nangona kungengazo zonke iimpawu ezidweliswe apha ngasentla, abo bakwishishini bayazi ukuba le yivalvu esebenza kakuhle. Ukuba inkampani esebenzisa uthutho olumanzi nayo kufuneka ifake ivalvu, ingaqwalaselwa.
