Yintoni isitywina esiguquliweyoivalvu yesango?
Ivalvu yesango lesitywino esiguquliweyo ithetha ukuba kukho umphezulu wokutywina phakathi kwesiqu sevalvu kunye nesihlalo sokutywina ngaphakathi kwebhonethi. Xa zivuliwe ngokupheleleyo, ziyadibana ukuze zidlale indima yokutywina, zinciphise ukukhukuliseka kolwelo ekupakisheni, kwaye zandise ubomi benkonzo yokupakishwa. Nciphisa amathuba okuvuza. Ngokubanzi, iivalvu zesango kunye neevalvu zeglobe zineemfuno zokutywina ezibuyela umva.
Kwimeko evulekileyo ngokupheleleyo yevalvu yesango lesitywino esiguquliweyo, kukho isakhiwo sokutywina kunxibelelwano phakathi kwediski kunye nesiqu sevalvu, nangaphakathi kwesiqu sevalvu kunye nebhonethi (oko kukuthi, ezantsi kwebhokisi yokuzalisa). Xa ivuliwe ngokupheleleyo, zombini ezi zinto zidibana kwaye zicinezelwe ukuze zitywinwe. Oku kunokunciphisa ukukhukuliseka kwepakeji kwibhokisi yokuzalisa ngoxinzelelo lwangaphakathi, kwandise ubomi benkonzo yokuzalisa, kwaye kunciphise amathuba okuvuza. Ngokubanzi, iivalvu zesango kunye neevalvu zeglobe zineemfuno zokutywina ezibuyela umva.
Iivalvu yesangoyenye yezona valve zisetyenziswa kakhulu kwi-shut-off medium circulation. Into yayo yokutywina yi-valve plate, ngoko ke i-gate valve ikwabizwa ngokuba yi-gate valve. Uninzi lwee-gate valves zii-valve zokutywina ezinyanzelekileyo, oko kukuthi, xa uvala i-valve, uxinzelelo kufuneka lufakwe kwi-valve plate. Xa i-gate valve ivuliwe ngokupheleleyo, indlela yokuhamba ithe tye, kwaye i-valve plate ayikhange ikhuhlwe yi-medium. I-inverted seal gate valve ixhotyiswe ngesixhobo sokutywina esiguqulweyo. Emva kokuba i-valve ivuliwe ngokupheleleyo, kwenziwa i-inverted seal, kwaye ukupakisha kunokutshintshwa phantsi kokusebenza okuqhelekileyo kwenkqubo.
INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.
