Isinyathelo Ngesinyathelo Umhlahlandlela Wokushintsha I-Butterfly Valve Rubber Seal

1. Isingeniso

Ukushintsha izigxivizo zenjoloba kumavalvu ovemvane kuyinqubo eyinkimbinkimbi edinga ulwazi lobuchwepheshe, ukunemba, namathuluzi afanele ukuze kuqinisekiswe ukusebenza kwevalvu nokuvala ubuqotho kuhlala kunjalo. Lo mhlahlandlela ojulile wezingcweti zokunakekela ama-valve nochwepheshe unikeza imiyalelo enemininingwane, izinqubo ezingcono kakhulu, namathiphu okuxazulula inkinga.

Ukugcina izihlalo zamavalvu ovemvane kubalulekile ukuze kuqinisekiswe ukuphila kwazo isikhathi eside nokusebenza kahle kwazo. Kodwa-ke, ngokuhamba kwesikhathi, izimpawu zenjoloba kumavalve ovemvane zingase ziwohloke ngenxa yezinto ezinjengokucindezela, izinga lokushisa, nokuchayeka kwamakhemikhali. Ngakho-ke, izihlalo ze-valve zidinga ukunakekelwa okuvamile ukuvimbela ukwehluleka nokwandisa impilo yalezi zingxenye ezibalulekile.
Ngaphezu kokugcotshwa, ukuhlolwa, nokulungiswa ngesikhathi ukuze kugcinwe esimweni esifanele, ukufaka izigxivizo zenjoloba kunezinzuzo ezinkulu. Yandisa ukusebenza kahle kwe-valve ngokuvimbela ukuvuza nokuqinisekisa uphawu oluqinile, ukunciphisa isikhathi sokuphumula nokuthuthukisa ukuthembeka okuphelele.
Lo mhlahlandlela uhlanganisa yonke inqubo kusukela ekulungiseleleni ukushintshwa kwezihlalo kuye ekuhlolweni kokugcina, futhi uhlinzeka ngezinyathelo ezibanzi nezinyathelo zokuphepha.

2. Ukuqonda ama-butterfly valves nama-rubber seal

2.1. Ukwakhiwa kwama-butterfly valves

Ama-valve e-butterfly akhiwe izingxenye ezinhlanu: umzimba we-valve,ipuleti le-valve, i-valve shaft,isihlalo se-valve, kanye ne-actuator. Njengesici sokuvala se-valve uvemvane, isihlalo se-valve sivame ukutholakala eduze kwe-valve disc noma umzimba we-valve ukuze kuqinisekiswe ukuthi uketshezi aluphumi lapho i-valve ivaliwe, ngaleyo ndlela igcine uphawu oluqinile, olungavuzi.

2.2. Izinhlobo zezihlalo ze-butterfly valve

Izihlalo ze-Butterfly valve zingahlukaniswa ngezinhlobo ezi-3.

2.2.1 Isihlalo sevalvu ethambile, okuyisihlalo sevalvu esishintshwayo esishiwo kulesi sihloko.

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

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

- I-Viton: ingasetshenziswa ekusetshenzisweni kokushisa okuphezulu ngenxa yokumelana nokushisa kwayo.

2.2.2 I-backrest eqinile, lolu hlobo lwesihlalo se-valve lungashintshwa, kodwa luyinkimbinkimbi kakhulu. Ngizobhala esinye isihloko ukuze sichaze kabanzi.

2.2.3 Isihlalo sevalvu esivuvukele, okuyisihlalo sevalvu esingashintsheki.

2.3 Izimpawu zokuthi isigxivizo serabha sidinga ukushintshwa

- Ukuguga okubonakalayo noma ukulimala: Ukuhlola ngokomzimba kungase kwembule imifantu, izinyembezi, noma ukonakala kophawu.
- Ukuvuza eduze kwevalvu: Ngisho nalapho uvalekile, uma uketshezi luvuza, uphawu lungagqokwa.
- Ukwanda kwe-torque yokusebenza: Ukulimala kwesihlalo se-valve kuzodala ukumelana nokusebenza kwe-valve butterfly.

3. Ukulungiselela

3.1 Amathuluzi nezinto ezidingekayo

Ukuze ubuyisele ngokuphumelelayo uphawu lwenjoloba ku-valve ye-butterfly, amathuluzi athile kanye nezinto ezidingekayo ziyadingeka. Ukuba nemishini efanele kuqinisekisa inqubo yokufaka esikhundleni eshelelayo neyimpumelelo.
- Ama-Wrenches, screwdrivers, noma ama-hexagon sockets: Lawa mathuluzi akhulula futhi aqinise amabhawodi ngesikhathi sokushintshwa. . Qiniseka ukuthi unesethi yama-wrenches alungisekayo, izikulufu ze-slotted kanye ne-Phillips, kanye nosayizi abahlukahlukene bamasokhethi anehexagon ukuze kuhlaliswe osayizi abahlukahlukene bamabhawodi.
- Izinto zokugcoba: Izinto zokugcoba, njengamafutha e-silicone, zidlala indima ebalulekile ekugcineni izingxenye ezihambayo zevalvu. Ukusebenzisa i-lubricant efanele kunciphisa ukungqubuzana futhi kuvimbela ukuguga.
- Isando serabha noma isando sokhuni: Senza isihlalo silingane ngokuqinile ngokumelene nomzimba wevalvu.
- Isihlalo sevalvu entsha: Isivalo senjoloba esisha sibalulekile ekushintsheni. Qinisekisa ukuthi uphawu luhlangabezana nokucaciswa kwe-valve kanye nezimo zokusebenza. Ukusebenzisa ama-seal ahambisanayo kuqinisekisa ukulingana okuqinile nokusebenza kahle.
-Izinto zokuhlanza: Hlanza indawo evalekile kahle ukuze ususe noma iyiphi imfucumfucu noma izinsalela. Lesi sinyathelo siqinisekisa ukuthi isihlalo esisha sifakwe ngendlela efanele futhi sivimbela ukuvuza ngemva kokufakwa.
-Amagilavu ​​okuzivikela kanye nezibuko: Qinisekisa ukuphepha kwabasebenzi.

3.2 Lungiselela ukushintshwa

3.2.1 Vala uhlelo lwamapayipi

 

Ngaphambi kokuba uqale ukufaka esikhundleni sesihlalo senjoloba ku-valve uvemvane, qiniseka ukuthi uhlelo luvalwe ngokuphelele, okungenani i-valve ekhuphuka nomfula uvemvane ivaliwe, ukuze kudedelwe ukucindezela nokuqinisekisa ukuthi akukho ukugeleza koketshezi. Qinisekisa ukuthi ingxenye yamapayipi icindezelekile ngokubheka igeji yokucindezela.

3.2.2 Gqoka izinto zokuzivikela

 

 

Ukuphepha kufanele kube yinto ehamba phambili kuwe ngaso sonke isikhathi. Gqoka izinto zokuzivikela ezifanele, okuhlanganisa amagilavu ​​nezibuko. Lezi zinto zivimbela izingozi ezingaba khona njengokuchaphaza kwamakhemikhali noma imiphetho ebukhali.

4. Faka esikhundleni isivalo senjoloba kuvalve uvemvane

Ukushintsha uphawu lwenjoloba ku-auvemvane valvekuyinqubo elula kodwa ebucayi edinga ukunakwa ngemininingwane. Landela izinyathelo ezingezansi ukuze uqinisekise ukushintshwa okuphumelelayo.

4.1 Ungayihlukanisa kanjani ivalve uvemvane?

4.1.1. Vula i-Butterfly Valve

Ukushiya i-valve disc endaweni evulekile ngokugcwele kuzovimbela ukuvinjelwa ngesikhathi sokuqaqa.

4.1.2. Khulula izinsimbi

Sebenzisa isikrufu ukuze ukhulule amabhawodi noma izikulufu ezivikela ukuhlangana kwevalvu. Susa lezi zinsimbi ngokucophelela ukuze ugweme ukulimaza umzimba we-valve.

4.1.3. Susa iValve Butterfly

Donsa ngokucophelela i-valve epayipini, usekele isisindo sayo ukuvimbela ukulimala emzimbeni we-valve noma idiski.

4.1.4 Nqamula i-actuator

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

4.2 Khipha isihlalo sevalvu endala

4.2.1. Susa uphawu:

Hlukanisa umhlangano we-valve futhi ususe ngokucophelela uphawu lwenjoloba endala.
