Ukuxilongwa kwempazamo kunye nesicwangciso sokukhusela sokukhusela iivalvu zeglowubhu yeflange yombane

I-Abstract: Njengenxalenye ebalulekileyo yeenkqubo zokulawula ulwelo, ukusebenza okukhuselekileyo, okuthembekileyo, kunye nokuzinzileyo kweevalve zeglobhu zombane ze-flange zichaphazela ngokuthe ngqo ukusebenza okuqhelekileyo kwenkqubo yonke. Nangona kunjalo, kwizicelo ezisebenzayo, iivalve zeglobhu zombane zeflange zinokufumana ukungasebenzi kakuhle okuchaphazela ukusebenza kwazo kunye nobomi benkonzo. Eli nqaku liphonononga ukuxilongwa kwempazamo kunye nezicwangciso zokukhusela zokukhusela iivalvu zeglowubhu yeflange yombane, ejonge ukubonelela ngereferensi eluncedo yobunjineli kunye nabasebenzi bobugcisa.

1,Intshayelelo

Iivalvu zeglowubhu yombane zisetyenziswa kakhulu kumashishini afana nepetroleum, iikhemikhali, isinyithi, kunye namandla, aneempawu zesakhiwo esilula, ukusebenza kakuhle kokutywina, kunye nokusebenza ngokulula. Nangona kunjalo, ngexesha lokusebenza kwexesha elide, ngenxa yezinto ezahlukeneyo, iivalve zeglobhu zombane zeflange zinokuba neempazamo ezinje ngokuvuza, ukuxinana, kunye nokungaguquguquki, okukhokelela kwiziphumo ezibi njengokuvalwa kwezixhobo kunye neengozi zemveliso. Ke ngoko, ukuqonda uxilongo lwempazamo kunye nezicwangciso zokhuseleko lolondolozo lwevalvu yeglowubhu yombane yeflange kubaluleke kakhulu.

2,Iintlobo kunye nezizathu zeempazamo kwiivalvu zeglowubhu yeflange yombane

1. Ukuvuza

Ukuvuza sesinye sezona mpazamo zixhaphakileyo zevalvu yeglowubhu yeflange yombane, kwaye ezona zizathu ziphambili zezi zilandelayo:

(1) Ukugqoka okanye umonakalo kwindawo yokutywina: Ngethuba lokusetyenziswa kwexesha elide, indawo yokutywina iyakwazi ukukhukuliseka okuphakathi kunye nokugqoka, okukhokelela ekunciphiseni kokutywinwa kokusebenza.

(2) Ukuguga kokuzalisa: Isigcwalisi yinxalenye ephambili yokuqinisekisa ukusebenza kokutywinwa kweevalvu zeglowubhu zombane. Emva kokusetyenziswa kwexesha elide, iyakwazi ukuguga, ukuguga kunye nokuvuza.

(3) Uguqulo lwesivalo sevalvu okanye isigqubuthelo sevalvu: Ngenxa yezinto zangaphandle ezifana nobushushu kunye noxinzelelo, umzimba wevalvu okanye isigqubuthelo sevalvu inokonakala, okukhokelela ekwandeni komsantsa phakathi kwemiphezulu yokutywina kunye nokubangela ukuvuza.

2. Waxinga

Ukubonakaliswa okuphambili kombane we-flange yokuvala i-valve yokuvala i-valve kukuba i-valve ayikho kwindawo okanye ayikwazi ukuvulwa kwaye ivalwe, kwaye izizathu zezi zilandelayo:

(1) Ukukhuhlana phakathi kwesiqu sevalve kunye nokupakishwa: Ukukhuhlana ixesha elide phakathi kwesiqu sevalve kunye nokupakishwa kubangela ukuguga komphezulu, okukhokelela ekwandeni kokukhuhlana phakathi kwesikhondo sevalve kunye nokupakishwa.

(2) Amalungu aphakathi: Amalungu aphakathi athanda ukuxinga phakathi kwediski yevalvu kunye nesitulo sevalvu, ebangela ukuba ivalve ijam.

(3) Ukunyuswa kwangaphakathi kweevalvu: Ukungcola kwidiphozithi ephakathi ngaphakathi kwevalve, ukwenza ukulinganisa, ukunciphisa iziteshi zangaphakathi zevalve kwaye kubangela ukuba ivalve ijame.

3. Iintshukumo ezingenakuguquguquka

Ukungaguquguquki kwesenzo sevalve yeglowubhu yeflange yombane kubonakaliswa ikakhulu ngesantya esicothayo sokutshintsha kunye netorque enkulu, kwaye izizathu zezi zilandelayo:

(1) Ukungasebenzi kakuhle kweMotor: I-motor kwi-activator yombane yonakele okanye ukusebenza kwayo kuncitshisiwe, okukhokelela kwitorque engonelanga.

(2) Ukungaphumeleli kwendlela yokuhanjiswa: Indlela yokuhambisa igugile, ikhululekile okanye yonakele, echaphazela ukuvula nokuvala isantya kunye ne-torque ye-valve.

(3) Isignali yokulawula okungaqhelekanga: Inkqubo yokulawula ingasebenzi kakuhle, ibangela iimpawu zokulawula ezingazinzanga kunye nokusebenza kwevalve engenakuguquguquka.

3,Indlela yokufumanisa impazamo kwiivalvu zeglowubhu yeflange yombane

1. Indlela yokujonga

Ngokujonga imeko yokusebenza, imeko yokuvuza, kunye nenqanaba lokupakisha ukunxiba kwevalve, jonga ukuba kukho ukungasebenzi kakuhle kwivalvu.

2. Indlela yokuxilongwa kakuhle

Ukusebenzisa izivamvo zesandi ukuqokelela imiqondiso yesandi ngexesha lokusebenza kwevalvu, ukuhlalutya iimpawu zesandi ukufumanisa ukuba i-valve iphosakele.

3. Indlela yokufumanisa ubushushu

Ukubeka iliso kutshintsho lweqondo lokushisa ngexesha lokusebenza kwevalve ngokusebenzisa izinzwa zobushushu, uhlalutye iindawo zobushushu obungaqhelekanga, kwaye ufumanise unobangela weempazamo.

4. Indlela yokufumanisa ukungcangcazela

Ukusebenzisa i-vibration sensors ukuqokelela iimpawu zokungcangcazela ngexesha lokusebenza kwevalve, ukuhlalutya iimpawu zokungcangcazela ukufumanisa ukuba i-valve iphosakele.

5. Indlela yokuxilonga i-Hydraulic

Hlalutya ukusebenza kwenkqubo kwaye uhlolisise imbangela yeziphene ngokufumanisa iiparameters ezifana noxinzelelo kunye nokuhamba ngaphakathi kwevalve.
