Ziziphi iintlobo zeevalvu zegesi

Kukho iintlobo ezininzi zeevalvu zegesi, ezinokwahlulwa ngokweendlela ezahlukeneyo zokwahlulahlula. Nazi ezinye zeentlobo eziphambili zeevalvu zegesi:

Uhlu ngokwendlela yesenzo

Ivalvu Ezenzekelayo

Ivalvu esebenza ngokuzenzekelayo ngokuxhomekeka kumandla egesi ngokwayo. Umzekelo:

1. Ivalvu yokujonga: Isetyenziselwa ukuthintela ngokuzenzekelayo ukubuya kwegesi kwipayipi.
2. Ivalvu yokulawula: Isetyenziselwa ukulungisa ukuhamba kwegesi yepayipi.
3. Ivalvu yokunciphisa uxinzelelo: Isetyenziselwa ukunciphisa ngokuzenzekelayo uxinzelelo lwegesi kwimibhobho nakwizixhobo.

Iivalvu ezine-Actuator

Ivalvu elawulwa ngesandla, ngombane, ngomoya, njl. Umzekelo:

1. Ivalvu yesango: Ilawula ukuhamba kwegesi ngokuphakamisa okanye ukwehlisa isango, elifanelekileyo kwiinkqubo ezifuna ukuvulwa okanye ukuvalwa ngokupheleleyo.
2. Ivalvu yeglobe: Isetyenziselwa ukuvula okanye ukuvala ukuhamba kwegesi yombhobho.
3. Ivalvu yoMthombo: Isetyenziselwa ukulungisa ukuhamba kwegesi yombhobho (qaphela umahluko kwivalvu elawulayo, ivalvu ye-throttle igxila ngakumbi kulawulo oluthile lokuhamba kwamanzi).
4. Ivalvu yebhabhathane: Ilawula ukuhamba kwegesi ngokujikeleza idiski, edla ngokusetyenziswa kwiinkqubo ezineedayamitha ezinkulu zepayipi.
5. Ivalvu yebhola: Ivalvu ejikelezayo elawula ukuhamba kwegesi ngokujikeleza ibhola enomngxuma. Inesantya sokuvula nokuvala esikhawulezayo kwaye itywina kakuhle.
6. Ivalvu yeplagi: Inxalenye yokuvala yi-plunger okanye ibhola, ejikeleza umgca wayo osembindini kwaye isetyenziselwa ukuvula okanye ukuvala ukuhamba kwegesi kwipayipi.

Uhlu ngokwemisebenzi

1. Ivalvu Evaliweyo: Isetyenziselwa ukudibanisa okanye ukusika igesi yombhobho, njengevalvu yokumisa, ivalvu yesango, ivalvu yebhola, ivalvu yebhabhathane, njl.njl.
2. Ivalvu yokujonga: Isetyenziselwa ukuthintela ukubuyela kwegesi, njengevalvu yokujonga.
3. Ivalvu yokulawula: Isetyenziselwa ukulungisa uxinzelelo kunye nokuhamba kwegesi, njengevalvu yokulawula kunye nevalvu yokunciphisa uxinzelelo.
4. Ivalvu yokusasazwa: Isetyenziselwa ukutshintsha indlela igesi ehamba ngayo kunye nokusasaza igesi, njengeplagi eneendlela ezintathu, ivalvu yokusasaza, ivalvu yesilayidi, njl.

Uhlu ngokwendlela yoqhagamshelo

1. Ivalvu yoqhagamshelo lweFlange: Umzimba wevalvu uneflange kwaye uqhagamshelwe kumbhobho ngeflange.
2. Ivalvu eneentambo: Umzimba wevalvu unemisonto yangaphakathi okanye yangaphandle, kwaye uqhagamshelwe kumbhobho ngemisonto.
3. Ivalvu edibeneyo: Umzimba wevalvu une-weld, kwaye uqhagamshelwe kumbhobho ngokuwelda.
4. Ivalvu eqhagamshelwe kwi-clamp: Umzimba wevalvu une-clamp, kwaye uqhagamshelwe kumbhobho nge-clamp.
5. Ivalvu eqhagamshelwe kwisleeve: Iqhagamshelwe kumbhobho ngesingxobo.

Uhlu ngokweemeko ezithile zesicelo

1. Ivalvu yeGesi kawonkewonke: Ikwabizwa ngokuba yivalvu ekwipayipi ephambili yegesi, isetyenziselwa ukulawula igesi yazo zonke iintsapho ukusuka phezulu ukuya ezantsi kwisakhiwo seyunithi yonke, kwaye isetyenziselwa kakhulu ukugcinwa nokulungiswa kwenkqubo yepayipi yegesi.
2. Ivalvu phambi kwemithaEmva kokungena kwigumbi lomhlali, ivalvu ephambi kwemitha yegesi yeyona switshi iphambili elawula umbhobho wegesi wangaphakathi womsebenzisi kunye nezixhobo.
3. Ivalvu phambi kwezixhobo: Isetyenziswa kakhulu ukulawula ukusetyenziswa kwezixhobo zegesi ezifana nezitovu zegesi kunye nezifudumezi zamanzi zegesi, ezinokwahlulwahlulwa ngokukodwa zibe ziivalvu ngaphambi kwezitovu kunye neevalvu ngaphambi kwezifudumezi zamanzi.
4. Ivalvu yokuzivalela ngegesi yombhobho: Ngokubanzi ifakwe ekupheleni kombhobho wegesi, sisithintelo sokhuseleko phambi kombhobho kunye nesitovu, kwaye idla ngokuba nevalvu esetyenziswa ngesandla. Kwimeko yokucima kwegesi, ukunikezelwa kwegesi okungaqhelekanga, ukuqhekeka kombhobho, njl.njl., ivalvu ezivala ngokwayo iya kuvala ngokuzenzekelayo ukuthintela ukuvuza kwegesi.
5. Ivalvu yesitovu segesi: Ivalvu yegesi esetyenziswa kakhulu ngabasebenzisi kubomi bemihla ngemihla inokungena umoya kwaye ivuthelwe kuphela ngokuvula ivalvu yesitovu segesi.

Isishwankathelo

Kukho iintlobo ezininzi zeevalvu zegesi, kwaye ukhetho kufuneka luqwalaselwe ngokupheleleyo ngokusekelwe kwiimeko ezithile zokusetyenziswa, iimfuno zokusebenza, imigangatho yokhuseleko kunye nezinye izinto.
