Iivalvu zeLug vs. Wafer Butterfly: Umahluko oPhambili kunye neSikhokelo

Iivalvu zebhabhathanezidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo kunye neegesi ezahlukeneyo. Phakathi kweentlobo ezahlukeneyo zeevalvu zeebhabhathane, iivalvu zeebhabhathane ze-lug kunye ne-waferiivalvu zebhabhathaneZimbini iindlela ezisetyenziswa kakhulu. Zombini ezi ntlobo zeevalvu zinemisebenzi eyahlukileyo kwaye zifanelekile kwiindlela ezithile zokusebenza.I-TWSkweli nqaku siza kuphonononga ukufana nokwahluka kwazo, sinethemba lokukunceda wenze izigqibo ezinolwazi xa ukhetha ivalvu efanelekileyo.

I. Ukufana phakathi kwabo.

1. UkusebenzaPi-rinciple.

Zombini iivalvu zebhabhathane zohlobo lwe-wafer kunye neevalvu zebhabhathane zohlobo lwe-lug zilawula isantya sokuhamba kwesixhobo ngokujikeleza idiski yevalvu. I-engile yokujikeleza kwediski yevalvu ingaba phakathi kwe-0 ukuya kwi-90 degrees kuphela, oko kuthetha ukuba, ivalvu ivuliwe ngokupheleleyo kwiidigri ezingama-90 kwaye ivaliwe ngokupheleleyo kwiidigri ezingama-0. Lo ngumgaqo osebenzayo weevalvu zebhabhathane.

2. KuyafanaUbuso ngobuso

Ivalvu yebhabhathane ye-wafer kunye nevalvu yebhabhathane ye-lug zenziwe ngohlobo oluncinci, oluthatha indawo encinci kwaye lufanelekile ukufakwa kwinkqubo yemibhobho enesithuba esincinci.

3. Uyilo olusemgangathweni:

Zombini ziyahambelana nemigangatho yemizi-mveliso yamazwe ngamazwe, kulula ukuzidibanisa neeflanges ezisemgangathweni, kwaye zinokutshintshwa lula kwiinkqubo ezikhoyo.

II.Intoni's umehluko?

Zombini iivalvu zebhabhathane zohlobo lwe-wafer kunye neevalvu zebhabhathane zohlobo lwe-lug zibhekisa kwimo yoqhagamshelo lweevalvu zebhabhathane, ezinobude obufanayo besakhiwo kunye neenjongo ezifanayo, kodwa kukho umahluko omkhulu kuyilo, ukufakelwa, ukusetyenziswa, iindleko, kunye nezinye izinto.

1.UyiloDiinketho

Ivalvu yebhabhathane yeLug: Zombini iziphelo zomzimba wevalvu zenziwe ngee-lugs ezinemisonto, ezilungele ngakumbi ukulungiswa kwevalvu.

Ivalvu yebhabhathane yeWafer: Ngokwahlukileyo koko, ayinazo izinto ezifakelwe ngemisonto, kodwa ibotshelelwe phakathi kweeflange ezimbini, kunye neebholiti ezidlula kwiflange yombhobho kunye nomzimba wevalve ukuze ilungiswe. Oko kukuthi, yenzelwe uxinzelelo lweebholiti ezicinezela iflange yombhobho.

2.UfakeloPinkqubo.

• I-Lugivalvu yebhabhathane:

Iivalvu zebhabhathane zeLug zifanelekile kwiipayipi ezifuna ukulungiswa rhoqo okanye ukuqhaqhwa rhoqo. Izixhobo zokufaka ezinemisonto kulula ukuzifaka nokuziqhaqha ngaphandle kokonakalisa yonke inkqubo yepayipi. Ivalvu yebhabhathane ephumayo ingafakwa ekupheleni kombhobho kwaye isetyenziswe njengevalvu yesiphelo.

- Qinisekisa ukuba ii-lugs zilungelelaniswe ngokuchanekileyo nee-flange bolts ukuze kuthintelwe uxinzelelo emzimbeni wevalvu.

- Sebenzisa izixhobo ezifanelekileyo ze-gasket xa kuyimfuneko ukuthintela ukuvuza, ingakumbi kwiinkqubo zoxinzelelo oluphakathi.

- Qinisa iibholithi ngokulinganayo ukuze kugcinwe uxinzelelo olufanayo ngaphakathi kwevalvu.

• Isonka esisicabaivalvu yebhabhathane:

Iivalvu zebhabhathane zeWafer zilungele ngakumbi ukudibanisa zombini iziphelo zemibhobho kwiimeko apho indawo incinci, kodwa azinakusetyenziswa njengeevalvu zesiphelo kuba zinokusuka.

- Qinisekisa ukuhambelana kweflange (umz. i-ANSI, i-DIN) ukuqinisekisa ukutywinwa.

- Kuphephe ukuqinisa kakhulu iibholithi zeflange ukuthintela ukuguguleka komzimba womatshini.

- Ifakwe kwinkqubo enentshukumo encinci yokuthintela ukukhululeka kwepayipi.

3. Indlela yokutywina.

Ivalvu yebhabhathane ye-lug inika isivalo esiqinileyo ngenxa yoqhagamshelo olunemisonto kunye neebholiti zokhuseleko, ukuqinisekisa ukusebenza okungenamanzi kwaye kuthintela ukubuya kolwelo.

Ngokwahlukileyo koko, ivalvu yebhabhathane yohlobo lwe-wafer ixhomekeke ekucinezelweni phakathi kweeflange ezimbini ukuze kufezekiswe ukutywinwa okuthembekileyo, ngoko ke kufuneka ifakwe ilungelelaniswe ngokupheleleyo nombhobho ukuze kuthintelwe ukungalungelelani nokuvuza.

4. I-DNkunyeI-PN

- I-wafer kwiivalvu zebhabhathane zihlala zincinci kune-DN600, kwaye iivalvu zebhabhathane ezine-flange enye zingasetyenziselwa ububanzi obukhulu. Ziqhelekile kwiimeko apho uxinzelelo luyi-≤ PN16.

-Ivalvu yebhabhathane ye-lug inobubanzi obukhulu kwaye inokumelana namanqanaba aphezulu oxinzelelo, ukuya kuthi ga kwi-PN25, kuba ukufakwa kwevalvu yebhabhathane ye-lug kukhuselekile ngakumbi.

5. Cuninzi

Iivalvu zebhabhathane zeLug kunye neevalvu zebhabhathane zewafer zahlukile ngendlela engabizi kakhulu.

Iivalvu zebhabhathane zeWafer zihlala zingabizi kakhulu kuba zinemizobo elula, kulula ukuyilungisa, kwaye azidingi zinto zininzi.

Ivalvu yebhabhathane ye-lug ifuna ukuthungwa ngemisonto, ngoko ke inkqubo yokwenziwa kwayo inzima kakhulu.

III. Cisiphelo

Zombini iivalvu ze-lug butterfly kunye neevalvu ze-wafer butterfly zisetyenziselwa ukulawula ukuhamba kolwelo, kodwa kukho umahluko omkhulu kuyilo, ukufakelwa, ukuvalwa, ububanzi, ukulinganiswa koxinzelelo, kunye neendleko phakathi kwezi zimbini. Xa ukhetha, oku kunokugqitywa ngokweemfuno ezithile: ukuba kufuneka ukuqhaqhwa rhoqo kunye nokugcinwa, kuyacetyiswa ukuba ukhethe uhlobo lwendlebe oluphumayo; Ukuba indawo incinci kwaye ixabiso liyinto exhalabisayo, i-wafer kuyilo ifanelekile ngakumbi. Ukuqonda la mahluko kunokukunceda ukhethe iivalvu ezihambelanayo ngakumbi kwaye ufezekise ulawulo lokuhamba olusebenzayo noluthembekileyo.I-TWSayiloqabane elithembekileyo kuphela lomgangatho ophezuluiivalvu zebhabhathanekodwa ikwanazo nezisombululo ezinzulu zobugcisa kunye nezisombululo ezivuthiweyo kwicandelo leiivalvu zesango, iivalvu zokujonga, ivalvu yokukhupha umoya, njl. Nokuba yeyiphi na indlela yokulawula ulwelo olufunekayo kuwe, singakunika inkxaso yobungcali nepheleleyo yevalvu yokumisa enye. Ukuba unenjongo yokusebenzisana okanye yokubonisana ngobuchwepheshe, nceda uzive ukhululekile ukunxibelelana nathi nangaliphi na ixesha.
