1. Chii chinonzi PTFE Fully Lined Butterfly Valve?
Mavharuvhu emhando yePTFE (polytetrafluoroethylene) anoshandiswa zvakanyanya mumapaipi ekugadzira zvinhu zvinoparadza zvakanyanya (senge maasidhi akasimba, mabhesi akasimba, uye zvinonyungudutsa zvakasikwa) nekuti muviri wevharuvhu nedhisiki zvese zvakafukidzwa nePTFE, zvichipa kudzivirira ngura uye kushanda zvakanaka kwekuvhara. Chimiro chemuviri wevharuvhu chakakamurwa kuita mhando mbiri: muviri une zvidimbu zviviri (muviri wakapatsanurwa) uye muviri une zvidimbu chimwe.chimiro chine zvidimbu zvivirindiyo dhizaini huru yemavharuvhu emhando yePTFE akazara nejira remabhuruvhu, nepo dhizaini yechinhu chimwe chete isingawanzoitiki, kunyanya nekuda kwekusakwana kwemaitiro ekuisa jira.
2. Kufanana
Saizi:DN50-DN600. Kusiyana nemavharuvhu emhando yebhatafurayi ane zvigaro zveEPDM, saizi shoma yezvigaro zvePTFE iDN50.
Kumanikidzwa:Yakaganhurirwa nezvinhu zvePTFE, kunyanya diski ine PTFE, yakakodzera kumanikidzwa kwakanyanya kwePN10 (PN16 inoda zvirevo zvakakosha).
Tembiricha:Tembiricha yekushanda iri -10 kusvika 180 degrees Celsius. (RPTFE inowanzova -20 kusvika 200 degrees Celsius)
3. Misiyano Mikuru uye Kuenzanisa
3.1 Hunhu hweMaumbirwo
Zvidimbu zviviriMuviri(Muviri Wakakamurwa): Muviri wevharuvhu une zvikamu zviviri (kana zvidimbu zviviri) zvakasanganiswa uye zvakabatana nemabhoti. Mupendero wacho unoumbwa pachikamu chimwe nechimwe chakasiyana usati waungana.
Muviri wechikamu chimwe chete (Muviri Wose):Muviri wevharuvhu unogadzirwa kana kugadzirwa sechikamu chimwe chete, uye jira racho rinoda kuumbwa nejekiseni kana kuti nzira yakakosha yekuputira zvakakwana.
3.2 Maitiro Ekugadzira
Muviri wevharuvhu yeshavishavi yakakamurwa:Muviri wevharuvhu une zvikamu zvepamusoro nepazasi zvakabatana nemabhoti. Lining yePTFE (kusanganisira mhete dzesilicone) inowanzo gadzirwa yoga isati yaungana. Nokudaro, maitiro e lining yemuviri une zvikamu zviviri ari nyore uye haadi maforoma kana maturusi chaiwo ekubatanidza.
Zvosemuviri wevharuvhu yeshavishavi: Muviri wevharuvhu unogadzirwa kana kugadzirwa sechinhu chimwe chete, pasina nzvimbo dzepakati dzekubatana. Mupendero wePTFE wakabatanidzwa nemuviri wevharuvhu kuburikidza nekuumba kana kusvibisa.
3.3 Kushanda Kwekuvhara
Zvidimbu zviviri (Muviri Wakakamurwa):Hapana kubuda kwemvura munzira mbiri (kusingapindi mabubbles), asi nzvimbo yacho inoda dhizaini yakanaka yekuvhara (senge maO-rings kana magaskets).
Chikamu chimwe chete (Muviri wese): Hapana nzvimbo dzemajoini, nzvimbo shoma dzinogona kubuda mvura, uye kuvimbika kwakanyanya kwekuvharwa.
3.4 Saizi Dzinoshanda
Zvidimbu zviviri (Muviri Wakakamurwa):Inowanikwa muDN50~DN600, uye saizi dzakakura dzinowanikwa zviri nyore.
Chidimbu chimwe chete (Monoblock Body): Zvinowanzogumira padhayamita diki; saizi hombe dzakaoma kugadzira.
3.5 Nyore Yekugadzirisa
Muviri wevharuvhu yeshavishavi ine zvidimbu zviviri:Zvakanakisa: Zviri nyore kupatsanura, hapana maturusi akakosha anodiwa, uye hafu ye lining kana dhisiki re butterfly zvinogona kutsiviwa zvakasiyana, zvichiita kuti kugadzirisa kuve nyore.
Muviri wevharuvhu yeshavishavi imwe chete:Zvakaipa: Zvakaoma kugadzirisa munzvimbo kana jira rakuvara; kazhinji zvinoda kutsiva muviri wese wevharuvhu.
3.6 Mutengo
Zvidimbu zviviri:Pamusoro pezvo, chigaro chePTFE chine mhete yesilicone mukati kuti chiwedzere kusimba uye kushanda kwekuvhara.
Chidimu chimwe: Yakaderera, kunyangwe maitiro ekuisa jira racho akaoma (PTFE haina kusimba uye yakaoma kupinza zvakafanana mumuviri wevharuvhu rimwe chete), uye kugadzira kwacho kwakaoma, kambani yedu ine tekinoroji yakakura, zvichikonzera mitengo yakaderera.
3.7 Maitiro Ekushandisa
Zvidimbu zviviri : Sarudzo huru, inonyanya kuwanikwa mumapaipi emakemikari, emishonga, emvura yakasviba, uye emagetsi anoparadza.
Chidimu chimwe: Inoshandiswa muzvinhu zvinonyanya kudiwa (sekunge zvinodiwa zvakanyanya zvekuvhara uye pasina zvinodiwa zvekugadzirisa), asi hainyanyo shandiswa mumavharuvhu ebhururu ane jira rakazara rePTFE.
