Umsebenzi we-Valve Gasket kanye nomhlahlandlela wokusebenzisa

Ama-gasket e-valve aklanyelwe ukuvimbela ukuvuza okubangelwa ukucindezela, ukugqwala, kanye nokwanda/ukufinyela kokushisa phakathi kwezingxenye. Nakuba cishe wonke e-flangeduxhumano's amavalvu adinga ama-gasket, ukusetshenziswa kwawo kanye nokubaluleka kwawo kuyahlukahluka ngohlobo lwevalvu kanye nomklamo. Kulesi sigaba,I-TWSizochaza izindawo zokufakwa kwamavalvu kanye nokukhethwa kwezinto ze-gasket.

I. Ukusetshenziswa okuyinhloko kwama-gasket kusekuhlanganeni kwe-flange yokuxhumeka kwe-valve.

I-valve esetshenziswa kakhulu

1. I-Valve yeSango
2. I-Globe Valve
3. I-valve yebhabhathane(ikakhulukazi ivalvu yebhabhathane ejiyile eqondile nephindwe kabili)
4. I-valve yokuhlola

Kula ma-valve, i-gasket ayisetshenziselwa ukulawula ukugeleza noma ukuvala ngaphakathi kwe-valve uqobo, kodwa ifakwa phakathi kwama-flange amabili (phakathi kwe-flange ye-valve uqobo kanye ne-flange yepayipi). Ngokuqinisa ama-bolts, kukhiqizwa amandla anele okubopha ukuze kudalwe uphawu olungaguquki, okuvimbela ukuvuza kwe-medium ekuxhumekeni. Umsebenzi wayo ukugcwalisa izikhala ezincane ezingalingani phakathi kwezindawo ezimbili ze-flange zensimbi, ukuqinisekisa ukuvalwa okungu-100% ekuxhumekeni.

II.Ukusetshenziswa kweGasket kuValve “Isembozo Sevalvu”

Ama-valve amaningi aklanywe ngemizimba yama-valve ehlukene kanye nezembozo ukuze kube lula ukulungisa ngaphakathi (isb., ukufaka esikhundleni izihlalo zama-valve, ama-valve e-disc, noma ukususa udoti), abese ehlanganiswa ndawonye. Kudingeka ne-gasket kulokhu kuxhumana ukuqinisekisa ukuvalwa okuqinile.

1. Ukuxhumana phakathi kwesembozo se-valve nomzimba we-valve yesango kanye ne-valve yomhlaba ngokuvamile kudinga ukusetshenziswa kwe-gasket noma i-O-ring.
2. I-gasket kulesi sikhundla iphinde isebenze njengesivalo esingaguquki ukuvimbela ukuthi i-medium ingavuzi emzimbeni we-valve iye emoyeni.

III. I-gasket ekhethekile yezinhlobo ezithile zama-valve

Amanye ama-valve afaka i-gasket njengengxenye yokuhlanganiswa kwawo kokuvala okuyinhloko, okwenzelwe ukuhlanganiswa ngaphakathi kwesakhiwo se-valve.

1. I-valve yebhabhathane-i-gasket yesihlalo se-valve

• Isihlalo se-butterfly valve empeleni siyi-gasket eyindandatho, ecindezelwa odongeni lwangaphakathi lomzimba we-valve noma efakwe eduze kwediski ye-butterfly.
• Lapho uvemvaneidiskiuma ivala, icindezela i-gasket yesihlalo se-valve ukuze yakhe uphawu oluguquguqukayo (njengoba uvemvaneidiskiiyajikeleza).
• Izinto zokwakha ngokuvamile ziyirabha (isb., i-EPDM, i-NBR, i-Viton) noma i-PTFE, eyenzelwe ukwamukela izimo ezahlukahlukene zemidiya kanye nokushisa.

2. I-Ball Valve-I-Gasket Yesihlalo Se-Valve

• Isihlalo sevalvu sevalvu yebhola siwuhlobo lwe-gasket, ngokuvamile esenziwe ngezinto ezifana ne-PTFE (polytetrafluoroethylene), i-PEEK (polyetheretherketone), noma amapulasitiki aqinisiwe.
• Ihlinzeka ngophawu phakathi kwebhola nomzimba wevalvu, okusebenza kokubili njengophawu olunganyakazi (uma kuqhathaniswa nomzimba wevalvu) kanye nophawu oluguquguqukayo (uma kuqhathaniswa nebhola elijikelezayo).

IV. Yimaphi ama-valve avame ukusetshenziswa nama-gasket?

1. Amavalvu ahlanganisiwe: Umzimba wevalvu uhlanganiswe ngqo epayipini, okususa isidingo sama-flange nama-gasket.
2. Amavalvu anezixhumanisi ezinezintambo: Ngokuvamile asebenzisa ukuvala okunezintambo (njengetheyiphu yezinto ezingavuthiwe noma i-sealant), ngokuvamile okuqeda isidingo sama-gasket.
3. Ama-valve e-Monolithic: Amanye ama-valve ebhola ashibhile noma ama-valve akhethekile anomzimba we-valve obalulekile ongenakuhlukaniswa, ngaleyo ndlela awunayo i-gasket ye-valve cover.
4. Amavalvu anezindandatho ze-O noma ama-gasket asongwe ngensimbi: Ezisetshenzisweni ezinomfutho ophezulu, izinga lokushisa eliphezulu, noma ezikhethekile, izixazululo zokuvala ezithuthukisiwe zingathatha indawo yama-gasket avamile angewona awensimbi.

Isifinyezo se-V.:

I-gasket ye-valve uhlobo lwento yokuvala ukhiye wokusika ejwayelekile, isetshenziswa kabanzi ekuxhumeni kwamapayipi ama-valve ahlukahlukene e-flange, futhi isetshenziswa nasekuvaleni isembozo se-valve sama-valve amaningi. Ekukhetheni, kubalulekile ukukhetha izinto ze-gasket ezifanele kanye nesimo ngokuya ngohlobo lwe-valve, imodi yokuxhuma, okuphakathi, izinga lokushisa kanye nengcindezi.
