Mulimo wa Valve Gasket & Bbuku Lyakubelesya

Zikwabilizyo zyamavalvu zyakabambilwa kutabilila kuvwundauka akaambo kakusinikizyigwa, kubola, akuvwuuma/kuvwundauka aakati kazibeela. Nikuba kuti zyoonse zili ama flangekujatana's mavalvu ayanda ma gasket, kubelesegwa kwawo abulemu bwawo zilaandeene kweendelanya amusyobo wamavalvu anzila mboakapangwa. Muchibeela eechi,TWSuyoopandulula busena bwakubikkila mavalvu akusala zibelesyo zyakukwabilila.

I. Kubelesya kutaanzi kwa gaskets kuli aawo mpokuswaangana flange ya valve.

Ivalvu iibelesyegwa kapati

1. Valve yamulyango
2. Globe Valve
3. Valve ya Butterfly(ikapati vvalavu yabutterfly iijisi mabbaaji aali akati-akati alimwi aali akati-kati)
4. Valve yakulanga

Mumavalvu aaya, chikwabilizyo tachibelesyegwi kweendelezya kweenda naa kujala mukati ka valve, pesi chibikkwa aakati ka flange yobile (akati ka flange ya valve a flange ya payipi). Kwiinda mukuyumya zibulo, manguzu aakujatilila aakkwene alapangwa kuti kube chijazyo chiyumu, kuchitila kuti kutabi kuvwundauka kwachintu aawo mpokuswaanganya. Mulimu wayo ngwakuzuzya tuzila tusyoonto tutali kabotu aakati kazibeela zyobile zyabutale, kuchitila kuti 100% yajala aawo mpoziswaangana.

II.Kubelesya Gasket mu Valve "Valve Cover"

Mavwili miingi akapangwa aamavwili aandeene azivwunisyo kuchitila kuti kube kuuba kubambulula mukati (nkokuti, kuchincha zyuuno zyamavwili, mavwili aadisiki, naa kugwisya tombe), eezyo mpawo zilaangidwe antoomwe. Gasket ayalo ilayandika aawo mpokujatikizigwa kuchitila kuti kujalwe kabotu.

1. Kuswaangana aakati kachivwumbyo cha valve amubili wa valve wa gate valve antoomwe a globe valve kanjikanji kuyandika kubelesya gasket naakuti O-ring.
2. Chikwabilizyo chili aawo mpochili chiimo eechi chibeleka mbuli chikwabilizyo chakutazungaana kuchitila kuti zintu zitazuzi kuzwa kumubili wa valve kuya mumulengalenga.

III. Gasket yaalubazu yamisyobo imwi yamavalvu

Amwi mavalvu abikkilizya gasket mbuli chibeela cha core sealing assembly, yakabambilwa kuti ibikkilizyigwe mukati kabupange bwa valve.

1. Valve ya Butterfly-valve seat gasket

• Chibbula cha valve ya butterfly mubwini nchintu chikwabilila, eecho chisinkilidwe mukati kabwaanda bwa valve naakuti chibikkidwe kuzinguluka disiki lya butterfly.
• Chiindi chiyunidisikikujala, kwasinikizya chibbula cha valve kuchitila kuti kube chijazyo chiyumu (mbuli butterflydisikiulazinguluka).
• Zibelesyo eezi kanjikanji zili a raba (nkokuti, EPDM, NBR, Viton) naa PTFE, zyakabambilwa kuti zibelesyegwe mubukkale bwiindene-indene bwakupya.

2. Bbola lyaValavu-Valve Seat Gasket

• Chibbula cha valve cha ball valve alubo nchintu chikwabilila, kanjikanji chipangwa azintu zilimbuli PTFE (polytetrafluoroethylene), PEEK (polyetheretherketone), naakuti mapulasitiki aasimide.
• Chipa chisinkilizyo aakati ka bbola amubili wa valve, mpawo chibeleka mbuli chisinkilizyo chitazungaani (kweendelana amubili wa valve) antoomwe achisinkilizyo chiyumu (kweendelana abbola lizungaana).

IV. Ino mavalvu nzi aatabelesyegwi ama gasket?

1. Mavalvu aajidwe: Mubili wavalvu ulaswaanganizyigwa kumupayipi, eezi zipa kuti kutayandiki ma flanges ama gaskets.
2. Mavalvu ajisi nsinga: Kanjaanji abelesya nsinga zyakujala (mbuli teepu yazintu zitabelesyegwi naa sealant), kanjikanji eezi zipa kuti kutayandiki ma gasket.
3. Mavwili aajisi zintu zilikke: Amwi mavwili aataduli kapati naa mavwili aalibedelede alijisi mubili wamavwili uutakonzyi kugwisyigwa, aboobo taakwe civwunisyo.
4. Mavalvu ajisi O-rings naakuti ma gaskets aajisi nsimbi: Muchiindi chiyumu, kupya kupati, naakuti zibelesyo zili akati-akati, nzila zyakujala zisumpukide zilakonzya kunjila mubusena bwama gaskets aatabelesyi nsimbi.

V. Mubufwaafwi:

Chikwabilizyo cha valve nchintu chijala kkii yakugela, chibelesyegwa kapati mukuswaanganya mapaipi aama flange valve aasiyene, alimwi chibelesyegwa mukujala valve ma valve manji. Mukusala, nkuko kuyandika kusala chibelesyo cheelede cha gasket akupanga kweendelanya amusyobo wa valve, nzila yakuswaangana, akati-kati, kupya akusinikizyigwa.
