Isebenza njani ivalve yebhola: Funda malunga nomatshini kunye nentengiso yeevalvu zebhola

Iivalvu zebhola zizinto ezibalulekileyo kwiinkqubo ezahlukeneyo zemizi-mveliso, ezilawula ngokuthembekileyo ukuhamba kolwelo kunye neegesi. Njengemveliso ehamba phambili kwimarike yevalve, iivalvu zebhola ziveliswa luluhlu olubanzi lwababoneleli, kubandakanya abavelisi beevalvu zebhola kunye neefektri eTshayina. Eli nqaku liza kuhlolisisa indlela ii-valve zebhola ezisebenza ngayo, iintlobo ezahlukeneyo ezikhoyo, kunye nezinto ezichaphazela amaxabiso e-valve yebhola, ngokugxininisa ngokukodwa kwi-carbon steel kunye ne-stainless steel valves.

Yintoni iValve yeBhola

Ivalve yebhola yivalve yekota esebenzisa ibhola enomngxuma, enemingxuma, ejikelezayo ukulawula ukuhamba kolwelo. Xa umngxuma webhola uhambelana nolwelo, ivalve iyavuleka, ivumela ulwelo ukuba ludlule. Ngokwahlukileyo, xa ibhola ijikeleziswa ngama-90 degrees, ukuhamba kuvaliwe kwaye i-valve ivalwe. Le ndlela elula kodwa esebenzayo yenza iivalve zebhola zibe yinto ethandwayo kwizicelo ezahlukeneyo, ukusuka kwimibhobho yokuhlala ukuya kwiinkqubo ezinkulu zemizi-mveliso.

Isebenza njani ivalve yebhola

Ukusebenza kwevalve yebhola kulula. Iqulathe amacandelo amaninzi abalulekileyo:

1. Umzimba weValve: Inxalenye ephambili yevalve egcina ibhola kunye nezinye izinto zangaphakathi.
2. Ibhola yeValve: Into engqukuva enomngxuma embindini, esetyenziselwa ukulawula ukuhamba kolwelo.
3. Isiqu: Intonga edibanisa ibhola kunye nomqheba okanye i-actuator, evumela ibhola ukuba ijikeleze.
4. Isihlalo seValve: Isitywina esingena ngokuqinileyo ngokuchasene nebhola ukuthintela ukuvuza xa ivalve ivaliwe.
5. Isibambo okanye iActuator: Indlela yangaphandle esetyenziselwa ukujika ibhola nokuvula okanye ukuvala ivalve.

INkqubo yokuSebenza

Xa isiphatho sijikwa, isiqu sijikeleza ibhola ngaphakathi kumzimba wevalvu. Ukuba imingxuma ebholeni ihambelana nendawo yokungena kunye nokuphuma, ulwelo lunokuhamba ngokukhululekileyo. Xa isiphatho sijikwa kwindawo evaliweyo, ibhola iyajikeleza kwaye inxalenye eqinileyo yebhola ivala indlela yokuhamba, ngokufanelekileyo ukuvala ulwelo.

Izinto ezilungileyo zevalve yebhola

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

- Ukusebenza ngokukhawuleza: Ukusebenza kwekota kuvumela ukuvulwa nokuvala ngokukhawuleza, okwenza kube yinto efanelekileyo kwiimeko zokuvala ngokukhawuleza.
-Ukwehla koxinzelelo oluphantsi: Idizayini yevalve yebhola inciphisa isiphithiphithi kunye nokulahleka koxinzelelo, iqinisekisa ukuhamba kakuhle.
-Ukuqina: I-valve yebhola yenziwe ngezinto ezinamandla, inokumelana noxinzelelo oluphezulu kunye nobushushu, obufanelekileyo kwiindawo ezahlukeneyo.
-Itywina eliQinisayo: Uyilo luqinisekisa ukutywinwa okuqinileyo, ukuthintela ukuvuza kunye nokuqinisekisa ukhuseleko kwizicelo ezibalulekileyo.

Iindidi zeevalvu zebhola

Kukho iindidi ezininzi zeevalvu zebhola, nganye inenjongo ethile:

1. Ivalve yeBhola edadayo: Ibhola ayilungiswanga kodwa ibanjwe luxinzelelo lolwelo. Olu hlobo ludla ngokusetyenziselwa izicelo zoxinzelelo oluphantsi.
2. Trunion Ball Valve: Ibhola ibanjwe yi-trunnion kwaye inokumelana noxinzelelo oluphezulu kunye nobukhulu obukhulu. Olu hlobo luhlala lusetyenziswa kwizicelo ezinkulu zamashishini.
3. I-V-Ibhola yeValve: Olu hlobo lubonisa ibhola ene-V evumela ukulawula ukuhamba kakuhle kwaye ifanelekile kwizicelo ze-throttling.

Izinto ezisetyenziselwa iivalvu zebhola

Ukhetho lwezixhobo zevalvu yebhola lubalulekile njengoko luchaphazela ukusebenza kwevalvu, ukuqina, kunye nokufaneleka kwenkqubo ethile. Izinto ezimbini eziqhelekileyo ezisetyenziselwa ukwenziwa kwevalvu yebhola yintsimbi yekhabhoni kunye nentsimbi engatyiwayo.

Carbon Steel Ball Valve
