- Kev Tiv Thaiv Kev Hnav: Nylon muaj kev ua tau zoo ntawm kev tiv thaiv kev hnav, nws tuaj yeem txo qhov khawb ntawm qhov chaw ntawm lub disc.
2.PTFE Lining Valve Disc
- Tsis nplaum: Qhov saum npoo ntawm PTFE disc yog nplua heev thiab tsis nplaum, nws tuaj yeem txo qhov nplaum los ntawm cov teeb meem nruab nrab.
- Kev tiv thaiv corrosion: PTFE muaj kev ua tau zoo tiv thaiv corrosive, nws hu ua King of plastic vim nws cov yam ntxwv tshwj xeeb tiv thaiv corrosive, nws tuaj yeem tiv taus ntau yam kua qaub thiab alkali media.
- Kev tsis muaj tshuaj lom neeg: PTFE yog qhov tsis muaj tshuaj lom neeg rau feem ntau ntawm cov tshuaj lom neeg. Nws tuaj yeem tiv taus kev xeb ntawm feem ntau ntawm cov tshuaj lom neeg.
- Kev Tiv Thaiv Kev Hnav: Txawm hais tias PTFE yog cov khoom siv mos mos, tab sis nws muaj kev ua tau zoo tiv thaiv kev hnav piv rau lwm cov yas txawm tias hlau. Lub disc nrog PTFE nto yuav muaj lub sijhawm ntev vim nws qhov feature.
3.Aluminium Bronze Valve Disc
Aluminium bronze yog ib qho hlau tooj liab uas feem ntau muaj txhuas, tooj liab thiab lwm yam khoom sib xyaw xws li manganese, hlau thiab zinc. Nws muaj ntau yam zoo uas ua rau nws siv dav hauv ntau yam kev siv.
- Kev tiv thaiv xeb zoo: Aluminium bronze muaj kev tiv thaiv xeb zoo heev, tshwj xeeb tshaj yog nyob rau hauv dej hiav txwv thiab dej ntsev. Qhov no ua rau nws yog ib qho khoom siv feem ntau hauv kev siv tshuab hauv hiav txwv thiab ntug dej hiav txwv xws li cov kiv cua nkoj, cov li qub thiab cov kav dej.
4. Nickel Phaj Npauj Npaim Valve Disc
- Cov yam ntxwv tiv thaiv kev xeb: Cov phaj nickel tuaj yeem tiv thaiv qhov chaw ntawm cov hlau ductile disc los ntawm kev xeb los ntawm cov xov xwm ua haujlwm.
- Kev Nyuaj Siab: Nrog nickel phaj, qhov chaw ntawm DI disc tuaj yeem ua kom tawv dua li yav dhau los. Nws tuaj yeem pab lub disc tiv thaiv los ntawm kev ua haujlwm nruab nrab teeb meem.
5. Roj hmab hauv ob sab hauv Valve Disc
- Kev ua haujlwm zoo ntawm kev kaw: Lub disc nrog cov roj hmab hauv yuav muaj kev ua haujlwm zoo heev piv rau lub disc hlau, yuav muab cov yam ntxwv txhim khu kev qha. Nws pab lub valve tiv thaiv kev xau.
6.Cov Npauj Npaim Valve Disc Uas Muaj Kev Nqus Siab
- Kev tsim tshwj xeeb ntawm cov disc siab-nqi muab kev ua haujlwm zoo heev. Raws li nws cov duab tshwj xeeb thiab qhov ntev raug, nws yuav txo qhov tsis kam thiab siab poob ntawm cov xov xwm ua haujlwm, ua tiav siab-nqi.
