Tilmaamaha Kuraasta Kuraasta Kubbadda: Hubka Qarsoon ee Shaabadaada

Tilmaamaha Kursiga Kubbadda ee Ball Valve: Hawlaha, Agabka (Kursiga PTFE & Waxyaabo kale) & Heerkulka | Shaabad Ugu Dambeysa

Dunidawaalka kubbadda, shaabad wax ku ool ah ayaa ugu muhiimsan. Shaqadan muhiimka ah waxaa ku jira qayb muhiim ah:Kursiga Ball Valve, badanaa si fudud loogu yeeroKursiga WaalkaHalyeeygan aan la heeso waa "horyaalka shaabadeynta" ee dhabta ah ee kooxda Ball Valve.

Waa maxay Kursiga Ball Valve-ka ee saxda ah

TheKursiga Ball Valvewaa qaybta muhiimka ah ee shaabadaynta ee ku jirtawaalka kubbaddaqaab-dhismeedka. Caadi ahaan waxaa laga sameeyaa walxo bir ah ama aan bir ahayn, waxaana lagu rakibaa gudaha jirka waalka. Doorkeeda ugu weyn waa inuu sameeyo isku-xidh adag oo shaabadaysan oo leh kubbadda wareegaysa. Iyadoo la ilaalinayo xiriirkan dhow,Kursiga WaalkaWaalka wuxuu awood u siinayaa inuu si kalsooni leh u xiro ama u habeeyo socodka dareeraha.

Khatarta Saddex-geesoodka ah ee Kursiga Valve: Wax ka badan Shaabad

Casri ahKuraasta Ball Valvewaxay leeyihiin awoodo cajiib ah oo ka baxsan shaabad aasaasi ah:

1. Shaabadeynta La-qabsiga (Qaab-beddelka):Sida barkin xumbo xusuusta ah oo u dhiganta madaxaaga, Kursiga Valve-ka ee tayada sare leh wuxuu ilaaliyaa dabacsanaan heerarka heerkulka aadka u daran (iyadoo la tixraacayo heerarka ASTM D1710, caadi ahaan -196°C ilaa +260°C). Ballacani wuxuu u oggolaanayaa inuu si toos ah u magdhabo xirashada yar ee dusha sare ee kubadda, taasoo hubinaysa hufnaanta shaabadda muddada dheer.

2. Agaasimaha Dareeraha (Ka Hortagga):Naqshado si gaar ah loo farsameeyay, sida Kuraasta Kubbadda V-port, ayaa si firfircoon u hagaya habka socodka. Socodka jihada ah wuxuu ka caawiyaa inuu baaro dusha sare ee shaabadaynta, isagoo ka hortagaya ururinta qashinka ama walxaha qashinka ah ee waxyeelayn kara shaabadda.

3. Jawaab-bixiyaha Degdegga ah (Badbaadada Dabka):Naqshadaha Kursiga Walafka qaarkood waxay ka kooban yihiin astaamo dab-badbaadinaya. Haddii ay dhacdo kulayl daran (sida dab), kuraastan waxaa loo sameeyay inay dab-shidaan ama kaarboon noqdaan. Lakabkaan kaarboonaysan ayaa markaa sameeya shaabad labaad, oo degdeg ah oo bir-ilaa-birta ah, taasoo ka hortagaysa guuldarro masiibo ah.

Sayniska Shaabaynta: Sida Kursiga Waalka u Shaqeeyo

Shaabadu waxay ku dhacdaa cadaadis jireed oo toos ah. Marka kubbadu u wareegto booska xiran, si adag ayay ugu riixdaaKursiga Ball ValveCadaadiskani wuxuu si yar u beddeshaa agabka kursiga, isagoo abuuraya caqabad aan daadan karin oo ka soo horjeeda dhexdhexaadka. Walxaha kubbadda caadiga ah waxay isticmaalaan laba Kursi oo Valve ah - mid ku yaal meesha laga galo iyo mid ku yaal dhinaca laga baxo. Xaaladda xiran, kuraastani si wax ku ool ah ayay u "qabsadaan" kubadda, iyagoo awood u leh inay u adkaystaan ​​​​cadaadiska ilaa 16MPa (halkiibaHeerarka API 6DNaqshado la xoojiyay, sida kuraasta V-port, waxay sii wanaajin karaan shaabadaynta iyada oo loo marayo xoogagga xiirashada ee la xakameeyey ee ka shaqeeya warbaahinta.

Heerkulka Kursiga Ball Valve: Arrimaha Maaddada

Xadka heerkulka hawlgalka ee aKursiga Ball Valvewaxaa aasaas ahaan lagu saleeyaa qaab-dhismeedka agabka. Waa kan kala-soocidda agabka kuraasta caadiga ah iyo heerarka heerkulka muhiimka ah:

Kuraasta Kubbadda Shaabadda Jilicsan (Ku salaysan Polymer & Elastomer):

•Kursiga PTFE (Polytetrafluoroethylene):Doorashada caadiga ah. Kuraasta PTFE waxay ku fiican yihiin iska caabbinta daxalka waxayna si kalsooni leh u shaqeeyaan inta u dhaxaysa-25°C ilaa +150°CCodsiyada adag ee u baahan baaskiil wadista soo noqnoqda, PTFE-ka saxda ah ee mashiinka lagu sameeyayKuraasta (gaaraya dulqaadka ±0.01mm) oo lagu daray kubbado si gaar ah loo dhammeeyay waxay keeni karaan in ka badan 100,000 wareeg oo aan lahayn daadasho - iyadoo la raacayo heerka adag ee shaabadda ISO 5208 Class VI.

• PCTFE (Polychlorotrifluoroethylene):Ku habboon adeegyada cryogenic. Si wax ku ool ah ayuu uga shaqeeyaa laga bilaabo-196°C ilaa +100°C.

• RPTFE (PTFE la xoojiyay):Waxaa loo hagaajiyay cimri dherer iyo heerkul sare. Kala duwanaansho ku habboon:-25°C ilaa +195°C, aad ugu fiican codsiyada wareegga sare.

• PPL (Polyphenylene):Wax soo saar xoog leh oo loogu talagalay uumiga. Ku isticmaal gudaha-25°C ilaa +180°C.

• Viton® (FKM Fluoroelastomer):Loogu yaqaan iska caabbinta kiimikada iyo awoodda heerkulka ballaaran (-18°C ilaa +150°C) Si taxaddar leh u isticmaal uumiga/biyaha.

• Silikoon (VMQ):Waxay bixisaa gaaritaan heerkul sare oo heer sare ah iyo firfircooni kiimiko oo heer sare ah (-100°C ilaa +300°C), badanaa waxay u baahan tahay daaweyn ka dib si loo helo xoog ugu fiican.

Buna-N (Nitrile Rubber – NBR):Ikhtiyaar dhaqaale oo badan oo loogu talagalay biyaha, saliidaha, iyo shidaalka (-18°C ilaa +100°C) Iska caabin wanaagsan oo xoqid ah.
