Umsebenzi weValve Gasket kunye neSikhokelo seSicelo

Iigasket zevalvu zenzelwe ukuthintela ukuvuza okubangelwa luxinzelelo, ukugqwala, kunye nokwanda/ukuxinana kobushushu phakathi kwezinto. Nangona phantse zonke zijijekileuqhagamshelo's Iivalvu zifuna iigasket, ukusetyenziswa kwazo kunye nokubaluleka kwazo kuyahluka ngohlobo lweevalvu kunye noyilo lwazo. Kweli candelo,I-TWSiza kuchaza iindawo zokufakelwa kweevalvu kunye nokukhethwa kwezinto zegasket.

I. Ukusetyenziswa okuphambili kwee-gaskets kukwindawo edibeneyo yeflange yoqhagamshelo lwevalvu.

Eyona valve isetyenziswa kakhulu

1. Ivalvu yeSango
2. Ivalvu yeGlobe
3. Ivalvu yebhabhathane(ingakumbi ivalvu yebhabhathane ejijekileyo neyi-eccentric ephindwe kabini)
4. Ivalvu yokujonga

Kwezi valve, i-gasket ayisetyenziselwa ukulawula ukuhamba okanye ukuvala ngaphakathi kwevalvu ngokwayo, kodwa ifakwa phakathi kweeflanges ezimbini (phakathi kweflange yevalvu ngokwayo kunye neflange yombhobho). Ngokuqinisa iibholiti, kuveliswa amandla aneleyo okubamba ukwenza isitywino esingashukumiyo, okuthintela ukuvuza kwesixhobo kwindawo yokudibanisa. Umsebenzi waso kukugcwalisa izithuba ezincinci ezingalinganiyo phakathi kweendawo ezimbini zeflange zesinyithi, ukuqinisekisa ukutywinwa kwe-100% kwindawo yokudibanisa.

II.Ukusetyenziswa kweGasket kwiValve “Valve Cover”

Iivalvu ezininzi zenzelwe ukuba zibe nee-valve bodies ezahlukeneyo kunye nezigqubuthelo ukuze kube lula ukugcinwa ngaphakathi (umz., ukutshintsha izihlalo zeevalvu, ii-disc valves, okanye ukususa inkunkuma), ezithi emva koko zibotshwe kunye. I-gasket nayo iyadingeka kolu qhagamshelo ukuqinisekisa ukuvalwa okuqinileyo.

1. Unxibelelwano phakathi kwesigqubuthelo sevalvu kunye nomzimba wevalvu yevalvu yesango kunye nevalvu yeglobhu ludla ngokufuna ukusetyenziswa kwegasket okanye i-O-ring.
2. I-gasket kule ndawo ikwasebenza njengesitywini esingashukumiyo ukuthintela ukuba i-medium ingavuzi emzimbeni wevalvu iye emoyeni.

III. I-gasket ekhethekileyo kwiindidi ezithile zeevalvu

Ezinye iivalvu zifaka i-gasket njengenxalenye yendibano yazo yokutywina eyintloko, eyenzelwe ukuba idityaniswe kwisakhiwo sevalvu.

1. Ivalvu yebhabhathane-igasket yesihlalo sevalvu

• Isihlalo sevalvu yebhabhathane yigasket yeringi, ecinezelwa eludongeni lwangaphakathi lomzimba wevalvu okanye efakwe kwidiski yebhabhathane.
• Xa ibhabhathaneidiskiivala, icinezela i-gasket yesihlalo sevalvu ukuze yenze isitywino esitshintshatshintshayo (njengoko ibhabhathaneidiskiiyajikeleza).
• Le nto idla ngokuba yirabha (umz., i-EPDM, i-NBR, i-Viton) okanye i-PTFE, eyenzelwe ukulungelelanisa iimeko ezahlukeneyo zemidiya kunye nobushushu.

2. Ivalvu yeBhola-I-Valve Seat Gasket

• Isihlalo sevalvu sevalvu yebhola sikwaluhlobo lwegasket, edla ngokwenziwa ngezinto ezifana ne-PTFE (polytetrafluoroethylene), i-PEEK (polyetheretherketone), okanye iiplastiki eziqinisiweyo.
• Ibonelela ngesitywino phakathi kwebhola kunye nomzimba wevalvu, esebenza njengetywino elingashukumiyo (xa kuthelekiswa nomzimba wevalvu) kunye nesitywino esitshintshayo (xa kuthelekiswa nebhola ejikelezayo).

IV. Zeziphi iivalvu ezingasetyenziswa rhoqo ngee-gaskets?

1. Iivalvu ezidityanisiweyo: Umzimba wevalvu udityaniswe ngqo kumbhobho, nto leyo esusa imfuneko yeeflanges kunye neegaskets.
2. Iivalvu ezineentambo ezidityanisiweyo: Zidla ngokusebenzisa intambo ezidityanisiweyo (ezifana neteyiphu yezinto eziluhlaza okanye i-sealant), nto leyo ephelisa imfuneko yee-gaskets.
3. Iivalvu zeMonolithic: Ezinye iivalvu zebhola ezingabizi kakhulu okanye iivalvu ezikhethekileyo zine-valve yomzimba edibeneyo engenakususwa, nto leyo ebangela ukuba kungabikho gasket ye-valve cover.
4. Iivalvu ezinee-O-rings okanye ii-gaskets ezisongiweyo ngesinyithi: Kwizicelo ezinoxinzelelo oluphezulu, ezishushu kakhulu, okanye ezisetyenziswa ngokukodwa, izisombululo zokuvala eziphambili zingathatha indawo yee-gaskets eziqhelekileyo ezingezizo ezesinyithi.

Isishwankathelo se-V.:

I-gasket yevalvu luhlobo lwento yokutywina izitshixo zokusika ngokubanzi, isetyenziswa kakhulu ekuqhagamshelweni kwemibhobho yeevalvu ezahlukeneyo zeflange, kwaye ikwasetyenziswa ekutywinweni kwevalvu yesigqubuthelo sevalvu kwiivalvu ezininzi. Ekukhetheni, kuyimfuneko ukukhetha izinto ezifanelekileyo zegasket kunye nefom ngokwehlobo lwevalvu, imo yoqhagamshelo, iphakathi, ubushushu kunye noxinzelelo.
