Zeziphi izinto ezisetyenziswayo ezisetyenziswayo zevali?

Zininzi iintlobo zeevalanga, kodwa umsebenzi osisiseko uyafana, oko kukuthi, ukudibanisa okanye ukunqunyulwa ukuhamba okuphakathi. Ke ngoko, ingxaki yokutywina yevali ibalasele kakhulu.

Ukuqinisekisa ukuba ivalve inokunqumla ukuhamba kakuhle kwendawo ngaphandle kokuvuza, kuyimfuneko ukuqinisekisa ukuba itywina le-valve lingasebenzi. Zininzi izizathu zokuvuza kwe-valve, kubandakanya uyilo olungenangqondo lwesakhiwo, indawo yokutywina engalunganga, iinxalenye ezingenamkhethe, zikhululwe zizinto eziphakathi kwe-valve kunye ne-bonnet, njl njl. Zonke ezi ngxaki zinokukhokelela ekutyhileni kakubi ivalve. Ewe, ngaloo ndlela kudala ingxaki yokuvuza. Ke ngoko, itekhnoloji yokutywina iValve yitekhnoloji ebalulekileyo enxulumene nokusebenza kweValve kunye nomgangatho, kwaye ifuna inkqubo kunye nophando olunzulu.

Izinto ezisetyenziswayo ezisetyenziswayo zeValves ikakhulu zibandakanya ezi ntlobo zilandelayo:

I-1. Nbr

Ukuchasana kweoyile ekuhleni kweoyile, ukuxhathisa okuphezulu, ukumelana nobushushu, ukunamathela ngokuqinileyo. Ukungancedi kwayo kukunganyangeki kobushushu obungaphantsi, ukumelana nokunganyangeki kwe-ozone, iipropathi zombane ezihlwempuzekileyo, kunye nexesha eliphantsi kakhulu.

2. I-EPDM

Elona nqanaba libalulekileyo le-EPDM kukunganyangeki kwe-oxido obalaseleyo, ukunganyangeki kwe-ozone kunye nokunganyangeki. Kuba i-EPDM yeyosapho Polyoolefin, ineempawu ezintle zokuziphatha.

I-3. Ptfe

I-PTFO inomchasi owomeleleyo, ukumelana neoyile enkulu kunye nezinyibilikisi (ngaphandle kwe-ketones kunye nee-Esters), ukumelana nemozulu kunye nokunganyangeki kwe-ozone, kodwa ukuxhathisa i-ozone, kodwa ukunganyangeki kwe-ozone, kodwa ihlwempu kakhulu.

I-4. I-iron yentsimbi

QAPHELA: I-Iron yentsimbi isetyenziselwa amanzi, igesi kunye neendaba zeoyile kunye neqondo lokushisa le≤I-100°C kunye noxinzelelo oluthile lwe≤I-1.6MPA.

I-5. I-Nickel-esekwe

QAPHELA: IZAKHONO ZICKEL-esekwe kwimibhobho ngeqondo lobushushu le -70 ~ 150°C kunye noxinzelelo lobunjineli pn≤I-20.5PA.

I-6. Ubhedu

Ubhedu Alloy lunokunxiba kakuhle kwaye ilungele imibhobho yamanzi kunye nemibhobho ye-steam kunye neqondo lobushushu≤200℃kunye noxinzelelo olufanelekileyo pn≤I-1.6MPA.
