Ea boraro, valve ea ho hlahloba serurubele: mofuta o otlolohileng.
Sebopeho sa valve ea ho hlahloba serurubele se tšoana le valve ea serurubele. Sebopeho sa sona se bonolo, se hanana le phallo e fokolang, khatello ea hamore ea metsi le eona e nyane. Lesela la valve le potoloha phini setulong sa valve sa valve ea ho hlahloba. Valve ea ho hlahloba mofuta oa disc e na le sebopeho se bonolo, e ka kenngoa feela phaepheng e otlolohileng, ho koala ha eona hoa fokola.
Sa bone, valve ea ho hlahloba diaphragm: ho na le mefuta e fapaneng ea sebopeho, kaofela e sebelisa diaphragm e le likarolo tsa ho bula le ho koala.
Ka lebaka la tshebetso ya yona ya hamore ya metsi, sebopeho se bonolo, ditjeo tse tlase, mme dilemong tsa morao tjena ntshetsopele ya lebelo le ho feta, valve ya diaphragm e se e sebediswa haholo. Empa tshebediso ya diaphragm hlahloba valve mocheso le kgatello ke dithibelo tsa thepa ya diaphragm.Valve ea ho hlahloba diaphragm e loketse ho hlahisa tšusumetso ea metsi habonolo phaepheng, diaphragm e ka ba ntle haholo ho felisa seaplane khahlanong le phallo ea metsi e hlahisoang ke tšusumetso, hangata e sebelisoa phaepheng ea mocheso o tlase oa tikoloho, haholo-holo e loketse liphaephe tsa metsi, mocheso o akaretsang oa seaplane o pakeng tsa -12 - 120 ℃ pakeng tsa khatello ea ts'ebetso ea <1.6MPa, empa valve ea ho hlahloba diaphragm e ka etsoa ho fihlela calibre e kholoanyane, boholo bo ka fihlelleha ho DN 2000mm kapa ho feta!
