Ivalve yebhabhathane kulwakhiwo lweklasi yetywina ethambileyo kunye nentshayelelo yokusebenza

Ivalve yebhabhathane isetyenziswa kakhulu kulwakhiwo lwasezidolophini, i-petrochemical, isinyithi, amandla ombane kunye namanye amashishini kumbhobho ophakathi ukwenza ukunqumla okanye ukulungelelanisa ukuhamba kwesixhobo esingcono. Ulwakhiwo lwevalvu yebhabhathane ngokwalo yeyona ndawo ifanelekileyo yokuvula kunye nokuvala kumbhobho, lukhokelo lophuhliso lweendawo zanamhlanje zokuvula nokuvalwa kwemibhobho. Sidla ngokuba nevalve yebhabhathane ethambileyo yomgca oseziko, esetyenziswa ikakhulu kubushushu obuqhelekileyo, kwiimeko zoxinzelelo oluphantsi, ezifana nonikezelo lwamanzi kunye nokuhanjiswa kwamanzi, iiprojekthi zogcino lwamanzi, ulwakhiwo lukamasipala kunye nezinye iindawo. Oku kulandelayo kwazisa ikakhulu ivalve yebhabhathane eccentric, ivalve yebhabhathane eccentric ephindwe kabini kunye neemveliso zevalve yebhabhathane eccentric kathathu.

Okokuqala, i-single eccentric structure yeivalve yebhabhathane ethambileyo, isihlalo ukutywina cross-icandelo okanye ipleyiti butterfly ubukhulu yolwalathiso umgca equidistant kunye nombindi ukujikeleza kwesiqu sevalve isihlobo eccentric, ukuze ivelufa butterfly kwinkqubo yokuvula, ipleyiti butterfly ipleyiti yokutywina umphezulu ngokuthe ngcembe kude ukusuka kwindawo yokutywina isihlalo sevalve. Butterfly ipleyiti ujikelezo ukuya 20 ~ 25 °, ipleyiti butterfly ipleyiti yokutywina umphezulu yahlulwe ngokupheleleyo ukusuka kwindawo yokutywina isihlalo sevalve, ukuze ivelufa butterfly kwinkqubo yokuvula, isalamane ukunxitywa koomatshini kunye extrusion phakathi kwemiphezulu ukutywina ezimbini kuncitshiswe kakhulu, ukuze ivalufa butterfly ukutywina ukusebenza kunokuphuculwa. Olu yilo luxhomekeke ikakhulu kwi-elastic deformation eveliswa yi-extrusion phakathi kwepleyiti yebhabhathane kunye nesihlalo sevalve ukuqinisekisa ukutywinwa kwevalve yebhabhathane.

Ngokwesiseko se-valve yebhabhathane enye eccentric, iziko elijikelezayo lepleyiti yebhabhathane lisuswa kumgca osembindini wendlela yevalve, eyenza ukuba ivalve yebhabhathane ibe yi-cam ngexesha lenkqubo yokuvula, ukuze indawo yokutywina yepleyiti yebhabhathane inokwahlulwa kumphezulu wokutywina wesihlalo sevalve ngokukhawuleza kunokwakheka kwe-eccentric enye. Xa ipleyiti yebhabhathane ijikeleza ukuya kwi-8 ° ~ 12 °, indawo yokutywina yepleyiti yebhabhathane yahlulwe ngokupheleleyo kumphezulu wokutywina wesihlalo sevalve. Uyilo lwesi sakhiwo lunciphisa kakhulu ukunxitywa komatshini kunye ne-extrusion deformation phakathi kweendawo ezimbini zokutywina, eziphucula ukusebenza kokutywinwa kwevalve yebhabhathane.

Kwaye kwisiseko seivalve yebhabhathane eccentric kabini, umgca osembindini wendawo yokutywina isihlalo wenza i-eccentricity ye-angular kunye nomgca ophakathi wevalve, eyenza indawo yokutywina ye-butterfly plate ikhuphe ngokukhawuleza ukusuka kwindawo yokutywinwa kwesihlalo ngexesha lokuvulwa ngexesha lenkqubo yokuvula i-butterfly plate, kwaye udibanise kuphela kwaye ucinezele indawo yokutywina isihlalo ngexesha lokuvala. Olu ludibaniso olulodwa lwe-eccentricity lusebenzisa ngokupheleleyo isiphumo se-cam, kuphelisa ngokupheleleyo ukukhuhlana komatshini kunye ne-abrasion phakathi kweendawo ezimbini zokutywinwa kwe-valve ye-butterfly valve yokutywina i-valve xa i-valve ivula kwaye ivale, kwaye isuse ukuba nokwenzeka kokukrala kunye nokuvuza. Isitywina esigqithisiweyo sitshintshiwe kwi-torque seal, kwaye ukulungiswa koxinzelelo lokutywinwa kufezekiswa ngokulungelelanisa i-torque yokuqhuba yangaphandle, ukwenzela ukuba ukusebenza kokutywinwa kunye nobomi benkonzo ye-eccentric structure etywinwe i-valve butterfly iphuculwe kakhulu.

Ngaphandle koko, i-Tianjin Tanggu Water Seal Valve Co., Ltd. yivalve yerabha ehleliyo yetekhnoloji ephucukileyo exhasa amashishini, iimveliso zisitulo esiluqilima ivalve yebhabhathane, ivalve yebhabhathane, ivalve yebhabhathane ephindwe kabini, ivalve yebhalansi, ivalve yokujonga ipleyiti ephindwe kabini,IValve yokukhupha umoya, Y-Strainer njalo njalo.
