Ivalvuiyithuluzi elivamile elizosetshenziswa ezimbonini eziningi futhi lidlala indima ebalulekile empilweni yokukhiqiza, kunezindawo ezithile ezibalulekile zokusetshenziswa kwama-valve.
1. Amavalvu amadivayisi asekelwe ku-oyili
Amadivayisi okucwenga uwoyela. Iningi lamavalvu asetshenziswa ekucwengisiseni uwoyela amavalvu epayipi, okuhlanganisa amavalvu esango, amavalvu embulunga, amavalvu okuhlola kanye namavalvu okusiza ngokwesilinganiso, amavalvu ebhola. Amavalvu esango alinganiselwa ku-80%.
Amadivayisi asetshenziswa ngefayibha yamakhemikhali. Imikhiqizo emikhulu yefayibha yamakhemikhali yifayibha yotshwala ye-polyester, i-acrylic kanye ne-polyvinyl alcohol. Ngokuvamile basebenzisa ama-ball valve nama-jacketed valve.
Amadivayisi asetshenziswa yi-Acrylonitrile. Avame ukusebenzisa ama-valve esango, ama-valve e-globe, ama-valve ebhola kanye nama-plug valve. Ama-valve esango enza cishe u-75% wama-valve aphelele.
Amadivayisi asetshenziswa yi-ammonia yokwenziwa. Ngokuvamile basebenzisa ama-valve esango, ama-valve e-globe, ama-valve okuhlola, ama-valve ebhola, ama-valve e-diaphragm, ama-valve enaliti kanye nama-valve okusiza alinganayo.
2. Amavalvu ezindaweni zeziteshi zamandla kagesi
Ukwakhiwa kwesiteshi sikagesi samanzi saseShayina kuthuthuka kuya ngasekuqondeni kwezindawo ezinkulu, ngokuvamile kusetshenziswa amavalvu okusiza ngokulingana, abalawuli bokunciphisa ingcindezi, amavalvu omhlaba anobubanzi obukhulu kanye nomfutho ophezulu.
3. Amavalvu endaweni yensimbi
Inqubo ye-aluminium oxide endaweni yensimbi idinga ama-valve embulunga, alawula ama-drain valve ； ama-valve ebhola okuvala insimbi, ama-valve e-butterfly azodingeka endaweni yokwenza insimbi.
4. Ama-valve endaweni ehlobene nolwandle
Kuzodingeka ama-valve engeziwe ezindaweni ezihlobene nolwandle kanye nokuthuthukiswa kwemboni kawoyela ogwini lolwandle, njengama-valve ebhola, ama-valve okuhlola kanye nama-valve emigwaqo eminingi.
