Yintoni iValve yeNnaliti kwaye Isebenza Njani

A ivalvu yenalitiyivalvu yokulawula ukuhamba komoya ngendlela echanekileyo eyenzelwe ukulawula amazinga okuhamba komoya amancinci kakhulu ngokuchanekileyo okuphezulu. Isetyenziswa kakhulu kwiinkqubo apho ukulungiswa okuncinci kubaluleke ngaphezu kokuvula okanye ukuvala ngokukhawuleza.

Yintoni iValve yenaliti

Ivalvu yenaliti luhlobo lwevalvu esetyenziselwa ukulawula ukuhamba kancinci kancinci nangokuchanekileyo.Igama layo livela kwisiqu eside, esincinci, esimile okwenaliti ngaphakathi komzimba wevalvu.Esi siqu sibukhali nesinciphileyo singena siphuma kwindawo encinci. Njengoko sihamba, sitshintsha ubukhulu bomngxuma. Oku kuvumela ulawulo oluchanekileyo kakhulu lolwelo okanye iigesi.

Iivalvu zeenaliti zifumaneka rhoqo kwi:Iinkqubo zezixhobo,Iigeyiji zoxinzelelo,Imigca ye-hydraulic,Iinkqubo zepetroli negesi,Iisekethe zolawulo zaselwandle nezemizi-mveliso

Azenzelwe inkonzo yokucima. Zenzelwe ukulungiswa kakuhle.

Izinto eziphambili zeValve yeNnaliti

• ①Umzimba wevalvu:Indlela yokuhamba kwamanzi ngaphakathi kwezindlu

• ②Inaliti (isiqu):Inde kwaye inciphile ukuze ilawulwe ngokuchanekileyo

• ③Isihlalo:Ifanisa imo yenaliti ukuze ivale kakuhle

• ④Ivili lesandla okanye i-actuator:Isetyenziselwa ukujika isiqu

• ⑤Ibhonethi kunye nokupakisha:Ithintela ukuvuza okujikeleze isiqu

Inxalenye nganye idlala indima ekufezekiseni uhlengahlengiso lokuhamba kwamanzi oluhamba kakuhle noluzinzileyo.

Isebenza njani iValve yeNdlebe

Xa ivili lesandla lijika:

• ①Isiqu siyashukumaezantsiukunciphisa ukuhamba kwamanzi

• ②Isiqu siyashukumaphezuluukwandisa ukuhamba kwamanzi

Njengoko inaliti enciphileyo isondela kwisihlalo, indlela yokuhamba kwamanzi iba ncinci.Njengoko irhoxa, umngxuma ukhula kancinci kancinci.

Olu yilo luvumela:Utshintsho oluhamba kancinci kakhulu.Ulawulo oluchanekileyo loxinzelelo.Imveliso ezinzileyo ngaphandle kokunyuka ngequbuliso

Ngenxa yokuba intshukumo ihambelana kwaye ilawulwa, abaqhubi banokwenza uhlengahlengiso oluncinci ngokuzithemba.

Kutheni iiValve zeNdle zibonelela ngoLawulo oluchanekileyo

• ①Ijiyometri yesiqu esithambileyo:Ivumela ukuguquguquka kokuhamba kakuhle

• ②Ubungakanani be-orifice encinci:Yehlisa ingxolo

• ③Intshukumo yesiqu esicothayo:Ithintela utshintsho olukhawulezileyo kuxinzelelo

Oku kuzenza zilungele iinkqubo ezihamba kancinci apho uzinzo lubaluleke ngaphezu kwesantya.

Ukusetyenziswa Okuqhelekileyo KweeValve Zeenaliti

Izixhobo kunye nokulinganisa:Zilawula ukuhamba komoya ukuya kwiigeyiji zoxinzelelo kunye neesensa.Oku kukhusela izixhobo ezibuthathaka ekonakalisweni.

Iinkqubo zeHydraulic kunye nePneumatic:Zilawula ukuhamba kolwelo okanye komoya kwimigca yokulawula.

Iinkqubo zoLwandle:Zisetyenziswa kwimigca yepetroli, kwiinkqubo zokuthambisa, nakwiindawo zokuthatha iisampulu apho ukuchaneka kubaluleke kakhulu.

Amashishini eeKhemikhali kunye neeNkqubo:Bajongana nokusetyenziswa kwedosi kunye nokulinganisa.

Ivalvu Yenaliti vs Ezinye Iintlobo Zevalvu

Xa kuthelekiswa neevalvu zebhola okanye zesango:

• ①Iivalufa zeenaliti zicotha ukusebenza

• ②Azifanelekanga ukuhamba kwamanzi amaninzi

• ③Zibonelela ngokuchaneka okuphezulu kakhulu kolawulo

Izinto ezisetyenziswa kwiivalvu zeenaliti

Izinto eziqhelekileyo ziquka:Ithusi.Yenziwe ngentsimbi eshayinayo.Intsimbi yekhabhoni.Isinyithi seMonel okanye i-alloy se-media ebolileyo

Ukukhethwa kwezinto kuxhomekeke kuxinzelelo, ubushushu, kunye nohlobo lolwelo.

Iingenelo eziphambili zeevalvu zeenaliti

• ①Ulawulo oluchanekileyo lokuhamba kwamanzi

• ②Ulawulo oluhle kakhulu ngesantya esiphantsi sokuhamba kwamanzi

• ③ Ukusebenza kakuhle kokutywina

• ④Uhlengahlengiso loxinzelelo oluzinzileyo

Imida Ekufuneka Iqwalaselwe

• ①Ayifanelekanga ukucima ngokukhawuleza

• ②Ayilungele ulwelo olungcolileyo okanye olugcwele amasuntswana

• ③Umthamo wokuhamba kwamanzi ulinganiselwe
