Ivalve yebhabhathane
Umgaqo osebenzayo wevalve yebhabhathane kukuqhuba ivalve yebhabhathane ejikelezayo kwi-valve shaft ukwenza idigri ezingama-90 ukuya phambili kunye nokujikeleza umva ukuvula nokuvala ivalve ukulawula ukuhamba. Ngokufakela isixhobo solawulo oluzenzekelayo okanye sombane, sinokulawulwa kude kwaye ngokuzenzekelayo. Nangona kunjalo, ngenxa yokukhawulelana kwesakhiwo somzimba we-valve, ayifanelekanga ukwenza i-high-temperature kunye ne-high-pressure valves. Iivalvu zebhabhathane ezinodayamitha ezikhulu zisetyenziswa ngokubanzi kuxinzelelo olungaphantsi kwe-4MPa naphakathi ngaphantsi kweedigri ezingama-400, kwaye ukusebenza kwazo kokutywina kukwabi kuneevalvu zesango kunye neevalvu zebhola. Ivalve yebhabhathane iphawulwa ngolwakhiwo olulula, umthamo omncinci kunye nokuvulwa nokuvala ngokukhawuleza, okulungele ngokukodwa ukwenza ivalve yebhabhathane enkulu. Ixabiso likwashibhile kunezinye iindidi zeevalvu.
Ivalve yesango
Inxalenye yokuvala yevalve yesango kukulawula ukuvuleka okuthe nkqo phezulu nasezantsi kunye nokuvala ukunqumla ukuhamba nge-screw, esetyenziswa ngokubanzi kuphela ukuvula ngokupheleleyo okanye ukuvala ngokupheleleyo, kungekhona njengomsebenzi olawulayo. Imodeli yokusetyenziswa inokusebenza kakuhle kokutywinwa kunye noxinzelelo olunoxinzelelo oluphakathi, olufanelekileyo ukwenza ubushushu obuphezulu kunye neevalve eziphezulu. Nangona kunjalo, umzimba wevalve yesango unokwakheka okukhulu kunye nesakhiwo esinzima. Iindleko ziphezulu ngokwentelekiso. Kwaye akufanele kubekho i-granular medium phakathi, ngaphandle koko kuya kuchaphazela ukuvala kunye nokutywinwa kwe-valve yesango lombane.
ivalve yebhola
Ivalve yebhola yindawo yokuvula neyokuvala, eyibhola. Ijikeleza ngokujikeleza kwe-90 degree yecandelo lokuvula kunye nokuvala. Isikhundla somngxuma wokuhamba kwebhola kwibhola silawulwa ukufezekisa umsebenzi wokuvula nokuvala i-valve. Ivalve yebhola inokusebenza kakuhle kokutywinwa kwaye ingasetyenziselwa uhlengahlengiso kunye nokunqunyulwa. Isenokwenziwa kwakhona kwindlela emithathu, ivalve yebhola eneendlela ezine. Ukufezekisa umsebenzi wokulawula imibhobho emininzi. Iingenelo zevalve yebhola kukuxhathisa ulwelo oluncinci, ukuvulwa ngokukhawuleza kunye nesantya sokuvala, akukhawulelwanga yinto ephakathi, inokuhamba ngeendlela ezimbini, ukutywinwa kweendlela ezimbini. Ngenxa yeempawu zesakhiwo, akukho lula ukubambelela kwizinto zangaphandle eziphakathi. Uxinzelelo lwebhere, olufanelekileyo kubushushu obuphezulu, ivalve yoxinzelelo. Umsesane wokutywina uqhele ukwenziwa ngeTeflon. Xa ubushushu obuphakathi buphezulu, ivalve yebhola eqinileyo inokukhethwa. Ngokubanzi, ibhola kunye nokutywinwa komphezulu wevalve yebhola eqinile kufuneka yenziwe lukhuni okanye itshizwe, enokumelana nobushushu obuphezulu, kodwa ixabiso liphezulu.
