Isebenza njani ivalvu yebhola: Funda ngendlela esebenza ngayo kunye nemarike yeevalvu zebhola

Iivalvu zebhola zizinto ezibalulekileyo kwiindlela ezahlukeneyo zokusebenza kwezoshishino, zilawula ngokuthembekileyo ukuhamba kolwelo kunye neegesi. Njengemveliso ephambili kwimarike yeevalvu, iivalvu zebhola ziveliswa ngababoneleli abahlukeneyo, kuquka abavelisi beevalvu zebhola abaziingcali kunye neefektri eTshayina. Eli nqaku liza kuhlola indlela ezisebenza ngayo iivalvu zebhola, iintlobo ezahlukeneyo ezikhoyo, kunye nezinto ezichaphazela amaxabiso eevalvu zebhola, kugxilwe kakhulu kwiivalvu zentsimbi yekhabhoni kunye neevalvu zebhola zentsimbi engatyiwayo.

Yintoni iValve yeBhola

Ivalvu yebhola yivalvu ejika ngekota esebenzisa ibhola engenanto, eneembobo, ejikelezayo ukulawula ukuhamba kolwelo. Xa umngxuma webhola uhambelana nolwelo, ivalvu iyavuleka, ivumela ulwelo ukuba ludlule. Ngokwahlukileyo koko, xa ibhola ijikeleziswa ngama-90 degrees, ukuhamba kuyavalwa kwaye ivalvu iyavalwa. Le ndlela ilula kodwa isebenzayo yenza iivalvu zebhola zibe lukhetho oludumileyo kwiindlela ezahlukeneyo zokusebenza, ukusuka kwiipayipi zasekhaya ukuya kwiinkqubo ezinkulu zoshishino.

Isebenza njani ivalvu yebhola

Ukusebenza kwevalvu yebhola kulula. Iqulathe izinto ezininzi ezibalulekileyo:

1. Umzimba weValve: Inxalenye ephambili yevalvu egcina ibhola kunye nezinye izinto zangaphakathi.
2. Ibhola yeValve: Into engqukuva enomngxuma embindini, esetyenziselwa ukulawula ukuhamba kolwelo.
3. Isiqu: Intonga edibanisa ibhola kunye nesiphatho okanye i-actuator, evumela ibhola ukuba ijikeleze.
4. Isihlalo seValve: Itywina elilingana kakuhle nebhola ukuthintela ukuvuza xa ivalvu ivaliwe.
5. Isiphatho okanye i-Actuator: Indlela yangaphandle esetyenziswa ukujika ibhola nokuvula okanye ukuvala ivalvu.

Indlela yokusebenza

Xa isiphatho sijikwa, isiqu sijikeleza ibhola ngaphakathi komzimba wevalvu. Ukuba imingxunya ebholeni ihambelana nendawo yokungena kunye nendawo yokuphuma, ulwelo lunokugeleza ngokukhululekileyo. Xa isiphatho sijikwa kwindawo evaliweyo, ibhola iyajikeleza kwaye inxalenye eqinileyo yebhola ivala indlela yokuhamba, ivale ngempumelelo ulwelo.

Iingenelo zevalvu yebhola

Iivalvu zebhola zibonelela ngeenzuzo ezininzi ezenza ukuba zibe lolona khetho lukhethwayo kwizicelo ezininzi:

- Ukusebenza ngokukhawuleza: Ukusebenza kwekota nganye kuvumela ukuvulwa nokuvalwa ngokukhawuleza, nto leyo eyenza kube yeyona ifanelekileyo kwiimeko zokuvala ezingxamisekileyo.
–Ukwehla koxinzelelo oluphantsi: Uyilo lwevalvu yebhola lunciphisa ukuxinana kunye nokulahleka koxinzelelo, okuqinisekisa ukuhamba kakuhle.
–Ukuqina: Ivalvu yebhola yenziwe ngezinto ezomeleleyo, inokumelana noxinzelelo oluphezulu kunye nobushushu, ifanelekile kwiindawo ezahlukeneyo.
–Isitywino Esiqinileyo: Uyilo luqinisekisa ukuvalwa okuqinileyo, luthintela ukuvuza kwaye luqinisekisa ukhuseleko kwiindawo ezibalulekileyo.

Iintlobo zeevalvu zebhola

Kukho iintlobo ezahlukeneyo zeevalvu zebhola, nganye inenjongo ethile:

1. Ivalve yeBhola edadayo: Ibhola ayizinzanga kodwa ibanjwe endaweni yayo luxinzelelo lolwelo. Olu hlobo ludla ngokusetyenziselwa ukusetyenziswa koxinzelelo oluphantsi.
2. Ivalvu yeBhola yeTrunion: Ibhola ibanjwe yi-trunnion kwaye inokumelana noxinzelelo oluphezulu kunye nobukhulu obukhulu. Olu hlobo luhlala lusetyenziswa kwizicelo ezinkulu zoshishino.
3. Ivalvu yeBhola ye-VOlu hlobo lunebhola enomfanekiso ongu-V evumela ulawulo olungcono lokuhamba kwamanzi kwaye ifanelekile kwiindlela zokuthomalalisa.

Izinto ezisetyenziselwa iivalvu zebhola

Ukukhethwa kwezinto zevalvu yebhola kubaluleke kakhulu kuba kuchaphazela ukusebenza kwevalvu, ukuqina kwayo, kunye nokufaneleka kwayo kwisicelo esithile. Izinto ezimbini eziqhelekileyo ezisetyenziswa ekuvelisweni kweevalvu zebhola yintsimbi yekhabhoni kunye nentsimbi engatyiwayo.
