Iivalvu zebhabhathane eziNyezo eziNthathu zizivalo ezisebenzisa icwecwe lebhabhathane ledisc ukujikelezisa ama-90 ° emva naphambili ukuvula, ukuvala okanye ukulungelelanisa okuphakathi ukulawula ukuhamba. Abanayo nje isakhiwo esilula, umthamo omncinci, ubunzima obulula, ukusetyenziswa kwezinto eziphantsi, ubungakanani obuncinci bokufaka, i-torque encinci yokuqhuba, ukusebenza okulula kunye nokukhawuleza, kodwa kunye nomsebenzi wokulawula ukuhamba kakuhle kunye neempawu zokuvala ukutywinwa. Iivalvu zebhabhathane eziThathu zisetyenziswa kakhulu kwisinyithi, amandla ombane, kushishino lwepetrochemical, unikezelo lwamanzi kunye ne drainage, ukwakhiwa kukamasipala kunye neminye imibhobho yoshishino enobushushu obuphakathi ≤ 425 ℃. Zisetyenziselwa ukulawula ukuhamba kunye nokusika ulwelo.
Iimpawu eziphambili zokwakha zeJLPVIvalve yebhabhathane kathathu ilandelayo:
1. Ulwakhiwo lwe-eccentric emithathu kunye nokusebenza ngeendlela ezimbini zokutywinwa
I-axis ye-valve stem iyatenxa kwiziko le-disc kunye neziko lomzimba ngaxeshanye, kwaye i-axis ejikelezayo yesihlalo sevalve ine-engile ethile kunye ne-axis yeshaneli ye-valve yomzimba. Idiskhi yokutywina idibanisa kuphela nesitulo sevalve xa ikwindawo evaliweyo, eyenza isihlalo sevalve kunye nepleyiti yebhabhathane iphantse inxibe-free. Amandla e-torque aveliswa ngexesha lenkqubo yokuvala, okwenza isihlalo sevalve sibe nomsebenzi wokutywina wokuvala ngokuqinileyo.
2. Isihlalo sevalve yebhabhathane kathathu sisitulo somzimba okanye isihlalo esingaphezulu, esenziwe ngezinto ezahlukeneyo.
Isakhiwo sesihlalo somzimba sevalve yebhabhathane ye-fitriple offset kukufaka isihlalo emzimbeni. Xa kuthelekiswa ne-disc kunye nesihlalo, kunciphisa kakhulu ithuba lokuba isihlalo siqhagamshelane nomendi ngokuthe ngqo, ngaloo ndlela kunciphisa iqondo lokukhukuliseka kunye nokwandisa ubomi benkonzo yesihlalo. Inkqubo yokujonga umphezulu wevalve yebhabhathane kathathu iqhutywa ngokungqongqo ngokungqinelana nenkqubo evunyiweyo yokuwelda umgangatho weWPS. Emva kwe-surfacing, unyango lokushisa, umatshini, ukucocwa ngokucokisekileyo kunye nokuhlolwa kuya kwenziwa kwi-welding surface ngokweemfuno ngaphambi kokuhlanganisana.
3. Uyilo lwesihlalo esinokubuyiselwa
Isihlalo sevalve siqulunqwe ishidi lensimbi engenasici kunye nephepha legraphite. Esi sakhiwo sinokuthintela ngokufanelekileyo impembelelo yesigxina esincinci esiphakathi kunye nokutywinwa kokubambisana kwendawo okubangelwa ukwanda kwe-thermal. Nokuba kukho umonakalo omncinci, akuyi kubakho ukuvuza.
4. Uyilo lwesiqu esichasene nokubhabha
Ukupakishwa kwesiqu akulula ukuba konakaliswe kwaye ukutywinwa kunokwethenjelwa. Ilungiswe kunye nepini ye-taper ye-disc, kwaye isiphelo sokwandiswa kwenzelwe ukukhusela isiqu ekuqhumeni xa intonga ye-valve iphukile ngengozi ekudibaneni kwentonga yevalve kunye ne-butterfly plate.
5. Isihlalo: isitywina esithambileyo kunye nesitywina esiqinileyo
Uluhlu lwe-JLPV ye-Triple Offset Butterfly Valve yoyilo loluhlobo lulandelayo:
1. Ubungakanani: 2 "ukuya ku-96" DN50 ukuya kwi-DN2400
2. Uxinzelelo: Iklasi 150lb ukuya 900lb PN6-PN160
3. Izinto eziphathekayo: i-carbon steel, insimbi engenasici kunye nezinye izinto ezikhethekileyo.
I-NACE MR 0175 i-anti-sulfur kunye ne-anti-corrosion metal materials.
4. Uqhagamshelo luphela: I-Flange, iWafer, Uhlobo lweLug ngokwe-ASME B 16.5
ASME B 16.25 kwiziphelo ze-butt welding.
5. Imilinganiselo yobuso ngobuso: ihambelane ne-ASME B16.10
6. Ubushushu: -29℃ ukuya ku-425 ℃
Iivalvu ze-JLPV zinokuxhotyiswa nge-gear operator, i-pneumatic actuators, i-hydraulic actuators, ii-actuator zombane, izixhobo zokutshixa, amavili amatsheyini, izikhondo ezongeziweyo kunye nezinye ezininzi ziyafumaneka ukuhlangabezana neemfuno zabathengi.
