Umhlahlandlela Wesinyathelo Ngesinyathelo Wokufaka I-Seal Yerabha Ye-Butterfly Valve

1. Isingeniso

Ukufaka izivalo zerabha kumavalvu ebhabhathane kuyinqubo eyinkimbinkimbi edinga ulwazi lobuchwepheshe, ukunemba, kanye namathuluzi afanele ukuqinisekisa ukuthi ukusebenza kwevalvu kanye nobuqotho bokuvala kuhlala kuphelele. Lo mhlahlandlela ojulile wochwepheshe bokulungisa amavalvu kanye nochwepheshe unikeza imiyalelo enemininingwane, imikhuba emihle kakhulu, kanye namathiphu okuxazulula izinkinga.

Ukugcina izihlalo zamavalvu ezimboza kubalulekile ukuqinisekisa ukuthi zihlala isikhathi eside futhi zisebenza kahle. Kodwa-ke, ngokuhamba kwesikhathi, izivalo zerabha kumavalvu ezimboza zingonakala ngenxa yezici ezifana nokucindezela, izinga lokushisa, kanye nokuchayeka kumakhemikhali. Ngakho-ke, izihlalo zamavalvu zidinga ukulungiswa njalo ukuze kuvinjelwe ukwehluleka nokwandisa isikhathi sokuphila kwalezi zingxenye ezibalulekile.
Ngaphezu kokuthambisa, ukuhlola, kanye nokulungisa ngesikhathi ukuze zigcinwe zisesimweni esihle, ukufaka izimbobo zerabha esikhundleni kunezinzuzo ezinkulu. Kwandisa ukusebenza kahle kwevalvu ngokuvimbela ukuvuza nokuqinisekisa ukuvalwa okuqinile, kunciphisa isikhathi sokungasebenzi kanye nokuthuthukisa ukuthembeka okuphelele.
Lo mhlahlandlela uhlanganisa yonke inqubo kusukela ekulungiseleleni ukushintshwa kwesihlalo kuya ekuhlolweni kokugcina, futhi unikeza izinyathelo eziphelele kanye nezinyathelo zokuphepha.

2. Ukuqonda ama-valve e-butterfly kanye ne-rubber seals

2.1. Ukwakheka kwamavalvu ebhabhathane

Amavalvu ebhabhathane akhiwe izingxenye ezinhlanu: umzimba wevalvu,ipuleti levalvu, umgodi wevalvu,isihlalo sevalvu, kanye ne-actuator. Njengesici sokuvala se-valve yebhabhathane, isihlalo se-valve sivame ukutholakala eduze kwediski ye-valve noma umzimba we-valve ukuqinisekisa ukuthi uketshezi aluphumi lapho i-valve ivaliwe, ngaleyo ndlela kugcinwa uphawu oluqinile, olungavuzi.

2.2. Izinhlobo zezihlalo zamavalvu ezivemvane

Izihlalo zamavalvu ezimpukane zingahlukaniswa zibe izinhlobo ezintathu.

2.2.1 Isihlalo sevalvu ethambile, okuyilokho isihlalo sevalvu esingashintshwa okukhulunywe ngaso kulesi sihloko esibhekisela kukho.

I-EPDM (i-ethylene propylene diene monomer rubber): imelana namanzi kanye namakhemikhali amaningi, ilungele ukwelashwa ngamanzi.

- I-NBR (irabha ye-nitrile): ifanele ukusetshenziswa kukawoyela negesi ngenxa yokumelana kwayo nowoyela.

- I-Viton: ingasetshenziswa ekusetshenzisweni kwezinga lokushisa eliphezulu ngenxa yokumelana kwayo nokushisa.

2.2.2 Isihlalo esingemuva esiqinile, lolu hlobo lwesihlalo se-valve lungashintshwa, kodwa luyinkimbinkimbi kakhulu. Ngizobhala esinye isihloko ukuze ngisichaze ngokuningiliziwe.

2.2.3 Isihlalo sevalvu esine-Vulcanized, okuyisihlalo sevalvu esingenakutshintshwa.

2.3 Izimpawu zokuthi uphawu lwerabha ludinga ukushintshwa

- Ukuguga noma umonakalo obonakalayo: Ukuhlolwa ngokomzimba kungaveza imifantu, ukudabuka, noma ukuguquka kwesivalo.
- Ukuvuza okuzungeze ivalvu: Ngisho noma ivaliwe, uma uketshezi luvuza, uphawu lungase luguge.
- Ukwanda kwe-torque yokusebenza: Ukulimala kwesihlalo se-valve kuzobangela ukwanda kokumelana kokusebenza kwe-valve ye-butterfly.

3. Ukulungiselela

3.1 Amathuluzi nezinto zokwakha ezidingekayo

Ukuze ufake uphawu lwerabha esikhundleni se-valve yebhabhathane ngempumelelo, kudingeka amathuluzi nezinto ezithile. Ukuba nemishini efanele kuqinisekisa inqubo yokufaka esikhundleni ebushelelezi nephumelelayo.
- Ama-Wrenches, ama-screwdriver, noma amasokhethi e-hexagon: Lawa mathuluzi akhulula futhi aqinise ama-bolts ngesikhathi senqubo yokuwashintsha. . Qiniseka ukuthi unesethi yama-wrenches alungisekayo, ama-slotted kanye nama-Phillips screwdriver, kanye nosayizi ohlukene wama-hexagon sockets ukuze avumelane nosayizi ohlukene wama-bolts.
- Izinto Zokugcoba: Izinto zokugcoba, njenge-silicone grease, zidlala indima ebalulekile ekugcineni izingxenye zevalvu zihamba. Ukusebenzisa i-lubricant efanele kunciphisa ukungqubuzana futhi kuvimbele ukuguguleka.
- Isando senjoloba noma isando sokhuni: Senza isihlalo silingane kahle nomzimba wevalvu.
- Isihlalo esisha se-valve: I-seal entsha yerabha ibalulekile enkambisweni yokushintshwa. Qiniseka ukuthi i-seal ihlangabezana nezimfuneko ze-valve kanye nezimo zokusebenza. Ukusebenzisa i-seal ehambisanayo kuqinisekisa ukulingana kahle nokusebenza kahle.
-Izinto zokuhlanza: Hlanza kahle indawo yokuvala ukuze ususe noma yikuphi ukungcola noma izinsalela. Lesi sinyathelo siqinisekisa ukuthi isihlalo esisha sifakwe kahle futhi sivimbela ukuvuza ngemva kokufakwa.
-Amagilavu ​​​​nezibuko zokuzivikela: Qinisekisa ukuphepha kwabasebenzi.

3.2 Lungiselela ukushintshwa

3.2.1 Vala uhlelo lwamapayipi

 

Ngaphambi kokuthi uqale ukushintsha isihlalo serabha ku-valve yebhabhathane, qiniseka ukuthi uhlelo luvaliwe ngokuphelele, okungenani i-valve engenhla kwe-valve yebhabhathane ivaliwe, ukuze kukhishwe ingcindezi futhi kuqinisekiswe ukuthi akukho ukugeleza koketshezi. Qinisekisa ukuthi ingxenye yepayipi incishisiwe ngokuhlola i-pressure gauge.

3.2.2 Gqoka imishini yokuzivikela

 

 

Ukuphepha kufanele kube yinto eza kuqala kuwe ngaso sonke isikhathi. Gqoka imishini yokuzivikela efanele, okuhlanganisa amagilavu ​​​​nezibuko. Lezi zinto zivimbela izingozi ezingaba khona njengokuchaphaza kwamakhemikhali noma imiphetho ebukhali.

4. Buyisela uphawu lwerabha ku-valve yebhabhathane

Ukufaka uphawu lwerabha esikhundleni se-aivalvu yebhabhathanekuyinqubo elula kodwa ebucayi edinga ukunakwa ngemininingwane. Landela izinyathelo ezingezansi ukuqinisekisa ukuthi ukufakwa esikhundleni kuphumelele.

4.1 Ungawuhlukanisa kanjani ivalvu yebhabhathane?

4.1.1. Vula iValve yeBhabhathane

Ukushiya idiski yevalvu ivulekile ngokuphelele kuzovimbela izithiyo ngesikhathi sokuyiqaqa.

4.1.2. Khulula izikhonkwane

Sebenzisa isikrufu ukuze ukhulule amabhawodi noma izikulufo eziqinisa ukuhlanganiswa kwevalvu. Susa lezi zinamathiselo ngokucophelela ukuze ugweme ukulimaza umzimba wevalvu.

4.1.3. Susa iValve Yebhabhathane

Khipha ivalvu ngokucophelela epayipini, usekele isisindo sayo ukuze uvimbele umonakalo emzimbeni wevalvu noma kwidiski.

4.1.4 Nqamula i-actuator

Uma i-actuator noma isibambo sixhunyiwe, sinqamule ukuze ufinyelele ngokugcwele emzimbeni wevalvu.

4.2 Susa isihlalo sevalvu esidala

4.2.1. Susa uphawu:

Hlukanisa i-valve assembly bese ususa ngokucophelela uphawu lwerabha oludala.
