A ivalve yebholasisivalo esivulwayo okanye esivalwe ngokujikelezisa ibhola kwisikhondo sevalve.Iivalve zebhola zinokwahlulwa zibe yi-2-port yebhola, i-3-port yebhola okanye i-4-port yebhola.Kwakhona, inevalve yebhola yombane kunye nevalve yebhola yepneumatic ukuhlangabezana neemfuno zakho zokuqalisa.Isetyenziswa ngokubanzi kwishishini lemichiza, ishishini lokunyanga amanzi, ishishini lokunkcenkceshela, ishishini lokwakha iinqanawa njalo njalo.

Iivalvu zebhola zinokulungiswa ngokweemfuno zeshishini lesicelo.Umzekelo, iivalvu zebhola zococeko zingasetyenziswa kwishishini lamayeza, kwishishini lesiselo, kunye neshishini lokucutshungulwa kwezinto eziphilayo kunye neemfuno eziphezulu.

Izinto ezilungileyo zevalve yebhola:

● Ukudinwa ngokupheleleyo

● Ukutywinwa okulungileyo, imfuno yetorque ephantsi

● Uyilo oluqinileyo

● Uyilo olwahlukeneyo lunokufaneleka kwizicelo kumashishini ahlukeneyo

Ukungalungi kwevalve yebhola:

● Ayilufanelanga ukufakwa kodaka okanye ukufakwa kwezixhobo apho okuphakathi kukho i-viscous noko

● Ukucocwa kwangaphakathi kwevalve yebhola akulula

● Ubungakanani bulinganiselwe

Iivalve zebhola zinokwahlulwa zibe ziivalve zebhola ezidadayo kunye neevalve zebhola zetrunnion.Ngokulula nje, ivalve yebhola edadayo ithetha ukuba ibhola izidada ngokuzenzekelayo ngaphakathi kumzimba wevalvu, ngelixa ibhola yevalve ye-trunnion imiliselwe kumzimba wevalvu, kwaye kukho ishafti ezinzileyo emazantsi omzimba wevalvu.Ibhola ye-valve yebhola ye-trunnion ixhaswa yi-valve stem kunye ne-trunnion ngexesha elifanayo, eyenza ibe yomelele kwaye iyancipha i-torque yokusebenza.

Ekhohlo: Ivalve yebhola edadayo ekunene: Ivalve yebhola yetrunnion

Umthombo: Tameson

Ngoko ke, i-valve yebhola ye-trunnion ifanelekile kakhulu ukusetyenziswa kwishishini loxinzelelo oluphezulu.Ngenxa yokuba ibhola ayihambanga kwaye idibene ne-trunnion, oku kuthetha ukuba iya kugcina ukutywinwa okufanelekileyo kumacala omabini kwaye ayiyi kwandisa iimfuno ze-torque.Konke kuzo zonke, kwishishini loxinzelelo oluphezulu, ivalve yebhola ye-trunnion iya kubonelela ngesisombululo esifanelekileyo kunye nekhwalithi ephezulu.

Ukusetyenziswa kwevalve yebhola yetrunnion:

Ishishini lemichiza: Iivalve zebhola ze-Trunnion zinokubonelela imboni yeekhemikhali ngokutywinwa kokusebenza kakuhle, isisombululo esikhuselekileyo kunye nesigxina.

Izityalo zamandla: Amaziko ombane aya kusebenzisa amafutha awohlukeneyo kwinkqubo yokuvelisa amandla, ngoko ke indawo ephakathi iya kuba nobushushu obuphezulu kunye neemfuno zoxinzelelo oluphezulu.Kule meko, i-valve yebhola ye-trunnion ifanelekile kakhulu kule shishini.

I-oyile kunye negesi yendalo: Iivalvu zebhola ze-trunnion zinokunceda kakuhle izityalo zegesi yendalo, iindawo zokucoca i-oyile, imibhobho yokubonelela ngegesi, njl.njl. ukufezekisa injongo yokusasaza kunye nokuvalwa.Ivalve yebhola yetrunnion inokumelana kakuhle nemfuno yoxinzelelo oluphezulu lweshishini.

Naziphi na iimfuno malunga nevalve yebhola yetrunnion, wamkelekile ukudibana nathi ukuze ufumane isisombululo sevalve yasimahla!
