Muaj ntau homnpauj npaim valve discRaws li kev siv cov npauj npaim li qub, qhov ntau thiab tsawg ntawm npauj npaim valve rau cov khoom lag luam yog los ntawm DN50-DN600, yog li peb yuav qhia cov valve discs raws li qhov ntau thiab tsawg siv tsis tu ncua.
1.Nylon Coated Valve Disc
Nylon txau yog cov khoom siv ntov ntov ntov ntom ntom nti uas ua rau cov kua nylon hauv cov kua ntawm cov av thiab cov duab nylon tom qab solidification. Nylon spray txheej muaj ntau yam kev siv thiab daim ntawv thov scenarios, ntawm no yog qee qhov kev siv:
- Anti-corrosive tiv thaiv: Nylon txheej tuaj yeem siv los ua qhov chaw tiv thaiv hlau. Nylon muaj cov yam ntxwv zoo dua los tiv thaiv corrosion, nws tuaj yeem cais cov hlau nrog sab nraud ntws nruab nrab, ncua lub neej ntev ntawm lub valve disc.
- Txo kev sib txhuam: Nylon muaj cov yam ntxwv zoo ntawm kev sib txhuam txo kev ua haujlwm, nws tuaj yeem yooj yim txo qhov kev sib txhuam ntawm lub rooj zaum valve thiab disc.
- Hnav-tiv taus: Nylon muaj kev ua tau zoo ntawm hnav-tiv taus, nws tuaj yeem txo qhov khawb ntawm qhov chaw disc.
2.PTFE hauv ob sab phlu Valve
- Tsis-nplaum: Nto ntawm PTFE disc yog nplua heev thiab tsis nplaum, nws tuaj yeem txo qhov nplaum los ntawm cov teeb meem nruab nrab.
- Corrosion tsis kam: PTFE muaj kev ua haujlwm zoo los tiv thaiv corrosion, nws hu ua Vaj Ntxwv ntawm cov yas vim nws muaj cov yam ntxwv tshwj xeeb los tiv thaiv corrosion, nws tuaj yeem tiv taus ntau cov kua qaub thiab alkali tawm.
- Chemical inertness: PTFE yog inertness rau feem ntau ntawm cov tshuaj. Nws tuaj yeem tiv thaiv corrosion ntawm feem ntau ntawm cov tshuaj.
- Hnav-resistant: Txawm hais tias PTFE yog cov khoom muag muag, tab sis nws muaj kev hnav-tiv taus zoo piv rau lwm cov yas txawm tias hlau. Ib tug disc nrog PTFE nto yuav muaj sij hawm ntev vim nws feature.
3.Aluminium Bronze Valve Disc
Aluminium bronze yog tooj liab alloy uas feem ntau muaj txhuas, tooj liab thiab lwm yam alloying xws li manganese, hlau thiab zinc. Nws muaj ntau yam zoo uas ua rau nws siv dav hauv ntau yam kev siv.
- Zoo corrosion kuj: Aluminium bronze muaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv dej hiav txwv thiab dej ntsev ib puag ncig. Qhov no ua rau nws ib txwm siv cov khoom siv hauv marine thiab offshore engineering daim ntaub ntawv xws li nkoj propellers, li qub thiab kav.
4.Nickel Phaj Npauj Npaim Valve Disc
- Cov yam ntxwv los tiv thaiv corrosive: Nickel phaj tuaj yeem tiv thaiv qhov chaw ntawm cov hlau nplaum los ntawm corroded los ntawm kev tshaj tawm ua haujlwm.
- Hardness: Nrog nickel phaj, qhov saum npoo ntawm DI disc tuaj yeem ua kom tawv dua li ua ntej. Nws tuaj yeem pab lub disc tsis kam los ntawm kev ua haujlwm nruab nrab obstacles.
5. Roj hmab hauv ob sab Valve Disc
- Kev ua tau zoo sealing: Lub disc nrog cov roj hmab hauv ob sab phlu yuav muaj kev sib khi zoo heev piv rau cov hlau disc, yuav muab cov kev sib khi zoo. Nws pab lub valve tiv thaiv kom tsis txhob tawm.
6.High Flow-rate Npauj Npaim Valve Disc
- Kev tsim tshwj xeeb ntawm qhov siab ntws-tus nqi disc muab kev ua haujlwm zoo heev. Raws li nws cov shafe tshwj xeeb thiab qhov tseeb qhov ntev, nws yuav txo qis qhov tsis kam thiab siab poob ntawm cov xov xwm ua haujlwm, ua tiav qhov siab txaus.
