Dooro Qalabka Kursiga Kuraasta Qalab ee Saxda ah ee Saxda ah
Xirmooyinka waalka kubbadda waxaa loo isticmaalaa warshado badan oo kala duwan. Maaddaama ay tahay hab aan caddayn lahayn ee cadaadiska iyo xakamaynta qulqulka, hawlgalkooda siman oo la isku halayn karo ayaa muhiim ah -taasi waa sababta alaabta polymer ay si aad ah ugu fiican tahay kuraasta valve valve.
Gawaarida kubbadda ayaa lagama maarmaan u ah inay u oggolaadaan inay gooyaan ama dhaafaan socodka iyo cadaadiska nidaamka tuubooyinka. Waxaa intaa dheer, waxaa loo isticmaalaa warshadaha sida petrochemical iyo farmashiyaha halkaas oo daadgurtu ay u matali karto cawaaqib xumo deegaanka ama alaabta lafteeda. Sidaa darteed, kursiga waalka kubbadda ayaa aad muhiim u ah xaaladahan oo kale maadaama ay mas'uul ka tahay xiridda dareeraha gudaha iyo u qaybinta culeyska fadhiga si isku mid ah.
Doorashada qalabka ku habboon ee waalka kubbadda ayaa muhiim ah si loo dammaanad qaado waxqabadka valve iyo badbaadada alaabta iyo deegaanka. Alaabooyinka kursiga kubadda ee ugu caansan waxaa ka mid ah PTFE,TFM, PTFE oo buuxa, PCTFE, PEEK, iyo POM.
HANTIDA MUHIIMKA AH EE AALADAHA KURSIGA Kubadda Kubadda
Markaad dooranayso walxaha polymer ee kursiga valve valve, waxaa jira arrimo badan oo ku lug leh. Waxyaabaha muhiimka ah waxaa ka mid ah…
● ductility ku filan si loo helo shaabad la isku halayn karo
● Degganaanshiyaha cabbirka si loo hubiyo in kursiga waalka kubbadda uu sii hayo qaabkiisa si loo xidho iyo waxqabad la isku halayn karo
● Khilaaf aad u hooseeya si aad u ilaaliso qulqulka stem ugu yaraan
● Balaadhinta kulaylka oo hooseeysa si kursiga waalka kubbadda uu u sii hayo qaabkiisa marka heerkulku isbeddelo
● Xiro aad u wanaagsan oo iska caabin ah nolosha adeeg dheer
● Waafaqid kiimikaad ee dhammaan warbaahinta ku lug leh
Sanado badan, oo ku salaysan faa'iidooyinkayada gaarka ah ee alaabta polymer-ka ee waxqabadka sare, waxaan sii wadeynaa inaan soo saarno noocyo badan oo jilicsan oo jilicsan oo loogu talagalay valves warshadaha.
Kursiga valve polymer-ka ee doorashada:
| Magaca Alaabta | Guryaha ugu muhiimsan | Notes | Range Heerkulka |
| PTFE | Isku dhafka aadka u hooseeya ee isku dhaca iyo iska caabin kiimiko oo aad u wanaagsan. | FDA,ROHS, REACH waa la oggolaaday | -40 ° C ilaa 260 ° C |
| 15% PTFE oo muraayad ka buuxo | Hoos u dhaca xoogga cadaadiska iyo qallafsanaanta hoose ee culeyska marka loo eego PTFE bikrad ah. | Walxaha xoqan Cadaadiska kulaylka | -40 ° C ilaa 260 ° C |
| 25% PTFE oo muraayad ka buuxo | Si la mid ah 15% galaas ayaa si fiican u xidha iska caabbinta kulaylka, xoog cadaadis sare leh iyo qallafsanaan hoose oo culeys ku jira. | Walxaha xoqan | -40 ° C ilaa 260 ° C |
| Birta Aan Lahayn ee Buuxiyay PTFE | Xiro aad u adag. Xoog aad u fiican iyo xasilloonida culeysyo xad dhaaf ah iyo heerkul sare. | Waxa loo isticmaali karaa codsiyada dareeraha kulaylka | -40 ° C ilaa 260 ° C |
| TFM | Qaab dhismeedka polymer cufan aad u badan marka loo eego Virgin PTFE. Waxay soo bandhigaysaa soo kabashada walaaca ka fiican. | Polymer PTFE oo la beddelay Waxqabadka la hagaajiyay | -40 ° C ilaa 260 ° C |
| Kaarboon Graphite buuxiyey TFM | Heerarka balaadhinta kulaylka hoose marka loo eego TFM-ga caadiga ah. | Ku habboon isticmaalka uumiga iyo codsiyada dareeraha kulaylka | -40°C ilaa 260°C iyo xataa 320°C ee codsiyada dareeraha kulaylka |
| UHMWPE | Aad bay ugu adkaysanaysaa kiimikooyinka daxalka ah, marka laga reebo asiidhka oksaydhka iyo dareerayaasha organic. | Sidoo kale loo yaqaan High Modulus Polyethylene (HMPE) ama Polyethylene Waxqabadka Sare (HPPE) | -50 ° C ilaa + 80 ° C |
| PCTFE | Aad ugu fiican isticmaalka cryogenic iyo oksijiinta. | Homo-polymer ee Chlorotrifluoroethylene | -240 ° C ilaa 120 ° C |
| Virgin PEEK 450G | Iska caabin kiimikaad oo heer sare ah iyo sifooyin farsamo oo heerkul sare leh. | Tamar-plastic polymer organic | -40 ° C ilaa 260 ° C |
| PEEK Kaarboon Kabuuxiyay | Guryo badan oo la mid ah Virgin PEEK. Si gaar ah ugu habboon heerkulka sare iyo xaaladaha culeyska sarreeya. | Isku-dhafan hoose oo isku dhac ah oo ku habboon codsiyo badan oo aadka u xun | -40 ° C ilaa 260 ° C |
| PFA | guryaha la midka ah ee Virgin PTFE.Sidoo kale loo yaqaan PTFE Soluble | Maaddada modules-ka sare oo bixisa labadaba awoodda heerkulka sare iyo cryogenic. | -80°C ilaa 260°C |
| Acetal iyo Delrin | Waxay muujisaa caabbinta wanaagsan ee xidhashada iyo qallafsanaanta culeyska hoostiisa. | Aad ugu fiican codsiyada kursiga valve | ilaa 80°C |
| VESPEL | Walax polyimide ah oo leh awood heerkul sare oo culeys ah oo inta badan loo isticmaalo codsiyada wareejinta kulaylka, gaaska kulul iyo saliidaha. | Waa inaan lagu isticmaalin STEAM | ilaa 80°C |
