Umsebenzi wesihlalo sevalve: isetyenziselwa ukuxhasa indawo evalwe ngokupheleleyo yondoqo wevalve kunye nokwenza iperi yokutywina.

Umsebenzi weDisc: I-Disc - i-disc ye-spherical eyenza ukuphakama kunye nokunciphisa ukuhla koxinzelelo. Kuqinisiwe ukwandisa ubomi benkonzo.

Indima yondoqo wevalve: Undoqo wevalve kuxinzeleloivalve yokunciphisalelinye lamacandelo aphambili okulawula uxinzelelo.

Iimpawu zesihlalo seValve: Ukonakala kunye nokunganyangeki; Ixesha elide lokusebenza; Ukumelana noxinzelelo oluphezulu; Ukuchaneka okuphezulu komgangatho; Ukuchasana okugqwesileyo kwimithwalo yokutyhala kunye nobushushu obuphezulu; Ilungele uninzi lweemoto zabakhweli, iilori ezilula nezinzima, iinjini zedizili kunye neenjini zoShishino ezimileyo.

Iimpawu zediskhi zeValve: Inomsebenzi ohlengahlengiswayo wokumisa ukuthintela udonga lweqokobhe lomzimba wevalvu ukuba lungangenwa. Ivalve yokujonga ipleyiti yebhabhathane yeclamshell inepini yehinge eyakhelwe-ngaphakathi, engapheleli nje ekupheliseni ukubakho kwehinge pin egqobhoza indlu yevalve ukuvuza, kodwa yenza isitulo sevalve lula ukusilungisa kuba isibiyeli esenziwe ngoomatshini sihambelana indawo yokuhlala yevalve. Lungisa idiski/isihlalo.

Iimpawu zondoqo wevalve: Xa undoqo ojikelezayo ujikeleza, ifolokhwe kwisiphelo esisezantsi sombindi ojikelezayo iqhuba ipleyiti yevalve eshukumayo ukuba ijikelezise, ​​ukuze umngxuma wokuphuma kwamanzi kwipleyiti yevalve eshukumayo ihambelane nomngxuma wokungena kwamanzi kwindawo ehambayo. ipleyiti yevalvu. ipleyiti yevalvu emileyo, kwaye ekugqibeleni amanzi aphuma kumbindi ojikelezayo. Ngokuphuma komngxuma, olu luyilo lusetyenziswa kakhulu kwiindawo zompompo.

Isishwankathelo sesihlalo seValve: Sebenzisa imathiriyeli yokutywina enwebekayo kunye ne-actuator encinci ukuze ufumane isitywina esingangeni moya. Uxinzelelo lokutywina lokucinezela isihlalo sevalvu kubangela ukuba izinto ziguge ngokunwebeka kwaye zicinezele kwindawo erhabaxa yecandelo lentsimbi yokukhwelana ukuze iplage nakuphi na ukuvuza. indlela. Ukungena kwemathiriyeli kulwelo sisiseko sokuvuza okuncinci.

Isishwankathelo sediski yevalve: umsesane wokutywina wediskhi wohlobo lwesiketi. Imodeli eluncedo idiza umsesane wokutywina wediskhi yodidi lwesiketi. Isici sayo sesakhiwo kukuba itywina phakathi kweringi yokutywina kunye nomzimba wediski yevalve luphawu oluphindwe kabini. Icandelo le-longitudinal kwindawo yokutywinwa phakathi kwendandatho yokutywina kunye nomzimba wediski ye-valve yindawo yendiza ye-trapezoidal.

I-valve core overview: I-valve core yinxalenye ye-valve esebenzisa ukuhamba komzimba we-valve ukufezekisa imisebenzi esisiseko yokulawula ulwalathiso, ukulawula uxinzelelo okanye ukulawula ukuhamba.

Inxalenye yobuso besiphelo esinokususwa kwivalve isetyenziselwa ukuxhasa indawo evalwe ngokupheleleyo ye-valve core kunye nokwenza iperi yokutywina. Ngokubanzi, i-diameter yesitulo sevalve yeyona dayamitha yokuqukuqela ephezulu yevalve. Umzekelo, iivalve zebhabhathane ziza kwizinto ezahlukeneyo zokuhlala. Isixhobo sesihlalo sevalve sinokwenziwa ngeerubha ezahlukeneyo, iplastiki, kunye nezixhobo zetsimbi, ezinje: EPDM, NBR, NR, PTFE, PEEK, PFA, SS315, STELLITE, njl.

Iimpawu zezinto eziphathekayo ekufuneka ziqwalaselwe xa ukhetha isitulo sevalve ethambileyo zezi:
1) Ukuhambelana kolwelo, kubandakanywa ukudumba, ukulahleka kobunzima, ukunyanzeliswa kunye nokuthotywa;
2) Ukuqina;
3) Ukuguqulwa okusisigxina;
4) Iqondo lokubuyisela emva kokususa umthwalo;
5) Amandla okuqina kunye noxinzelelo;
6) Ukuguqulwa ngaphambi kokuqhekeka;
7) Imodyuli ye-elastic.

undoqo wevalvu
I-valve core yinxalenye yevalve esebenzisa ukunyakaza kwayo ukufezekisa imisebenzi esisiseko yokulawula ulwalathiso, ukulawula uxinzelelo okanye ukulawula ukuhamba.

Ukuhlelwa
Ngokwendlela yokuhamba, ihlulwe ibe yintlobo yokujikeleza (45 °, 90 °, 180 °, 360 °) kunye nohlobo lokuguqulela (i-radial, i-directional).
Ngokwemilo, inokuthi yahlulwe ngokubanzi ibe yingqukuva (ivalve yebhola), iconical (ivalve yeplagi), idiski (ivalve yebhabhathane, ivalve yesango), idome-shaped (ivalve yokumisa, ivalve yokukhangela) kunye necylindrical (ivalve yokubuyisela umva).
Ngokuqhelekileyo zenziwe ngobhedu okanye insimbi engenasici, kukho iiplastiki, inayiloni, iiseramics, iglasi, njl.
Isiseko sevalve kwivalve yokunciphisa uxinzelelo yenye yezona zinto ziphambili zokulawula uxinzelelo.
