Ishishini lemichiza lishishini elinobume oburhabaxa, izixhobo ezifana nemibhobho kunye neevalvu zidlala indima ebalulekileyo kushishino lwale mihla lwemichiza.Iivalvu zicelwa umngeni ziimeko ezingqongileyo ezirhabaxa ekuhambiseni imibhobho enje ngomgubo, iigranule, kunye nodaka oluludaka, kwaye zihlala ziqhelene nokunxitywa kwemibhobho yevalvu kunye nokusilela.Ngoko ke, kufuneka sisebenzise into eqinileyo yokuguga, i-corrosion-resistant-resistant-resistant-resistant-resistant-corrosion-resistant-resistant-corrosion-resistant-resistant-resistant-resistant-corrosion-resistant-rosion-resistant-resistant-resistant-corrosion-resistant-resistant-corrosion-resistant-resistant-resistant-corrosion-resistant-resistant-corrosion-resistant-resistant-corrosion-resistant-resistant-resistant-corrosion-resistant-resistant-corrosion-resistant-resistant-resistant-corrosion-resistant material) ukwenzela ukuba i-valve ibe nobomi obude benkonzo, kwaye i-carbide ene-cemented iyona nto ingcono kakhulu.I-Zhuzhou Chuangrui Cemented Carbide Co., Ltd. iya kukwabelana nawe ukuba kutheni i-sintered sintered cemented carbide kufuneka ikhethwe njengesixhobo seevalvu kunye nezixhobo zemibhobho kwishishini lemichiza.
Kwishishini lemichiza yamalahle, udaka kunye nezinye iipayipi zothutho zezinto eziphathekayo, indawo yokutywina yevalve ayixhomekeke kuphela kwi-sliding friction kunye nokunxiba kweendawo ezincedisayo zokutywina, kodwa kunye nokumelana nempembelelo yesantya esiphezulu se-gas-solid duplex. umxube kunye nobushushu obuphezulu kunye nobunzima obuphezulu, kunye nokudanyaza kunye ne-cavitation ebangelwa yi-high-pressure fluid, ekhokelela kumonakalo kwaye ikhulise ukungaphumeleli kwevalve.Ngoko ke, phantsi kweemeko ezinzima zokusebenza ezifana nokuthuthwa kwepowder, ukuxhathisa ukugqoka kuyinkomba ebaluleke kakhulu yokuvavanya ukusebenza kwevalve.
Sikhetha i-sintered tungsten carbide njengesixhoboukwenza i-valve, engenawo amandla aphezulu kuphela, kodwa inokugqiba okuphezulu, xa isetyenziselwa ezinye izinto, i-coefficient ye-friction incinci kunentsimbi, enokunciphisa kakhulu ukuxhatshazwa kwendawo yokudibanisa kunye nokunciphisa ngokufanelekileyo i-torque yokusebenza.
I-integral sintered tungsten carbide yenziwe ngokufudumeza umxube we-tungsten kunye nekhabhoni kubushushu obuphezulu, uninzi lwe-tungsten carbide inobunzima obuphezulu,ngoko ke akukho lula ukubola kwiqondo lokushisa eliphezulu, kwayekananjaloinokumelana ne-oxidation elungileyo.
Kwivalve yegesi yamalahle, idiskhi yevalvu kunye nesitulo sevalvu zenziwe nge-sintered tungsten carbide ukwenza iperi yokutywina, kwaye ivalve inezi zinzuzo zilandelayo ezicacileyo.:
1,Ukuqina okuphezulu.ubunzima> 80HRC, enokumelana nokukhukuliseka kwesantya esiphezulu se-multiphase particle media ezifana ne-coal-water slurry, i-pulverized coal, i-silica fume, njl.
2,Ukumelana nobushushu obuphezulu.Inokusebenza kuyo750°C ubushushu obuphezulu ixesha elide, kwaye amandla ayo, ukubambelela kunye nokwandiswa kwe-thermal akukhawulelwanga ngamaqondo obushushu, ahlangabezana ngokupheleleyo neemeko zobushushu obuphezulu njengeshishini lemichiza yamalahle..
3,Ukumelana noxinzelelo oluphezulu.Amandla okuqhekeka okunqamlezayo kwe-sintered tungsten carbideunakoukufikelela 4000MPa, nto leyo ngaphezu 10 amaxeshaof intsimbi eqhelekileyo.
4,I-Corrosion-resistantce.I-carbide ene-sintered cemented iyonke izinzile ngokwekhemikhali, ayinyibiliki emanzini nokuba ishushu, kwaye ayidibani ne-hydrochloric acid kunye ne-sulfuric acid.
5,Aibrasion resistance.Iimpawu zobunzima obuphezulu kunye nokuzinza okuphezulu kwe-sintered sintered cemented carbide iqinisekisa ukusebenza okugqwesileyo kokuchasene nokunxiba kokutywinwa kwe-sub-material..
6Erosion Resistance.
Ngokubanzi, i-sintered sintered tungsten carbide cemented carbide inamandla amakhulu, ubunzima obuphezulu, indawo yokunyibilika ephezulu, uzinzo oluphezulu, i-coefficient ephantsi ye-friction, ukumelana nokunxiba, ukumelana nokhukuliseko kunye ne-cavitation, ukuxhathisa ukubola, kunye nokuveliswa kwezitywina zevalve ezingagugiyo. iimeko zokusebenza ezinzima kunokuphucula kakhulu ukusetyenziswa kwevalve, ukwandisa uluhlu lokusetyenziswa kwevalve, kunye nokwandisa ubomi bokusebenza kwevalve.
I-Zhuzhou Chuangrui Cemented Carbide Co., Ltd. ibonelela ngezixhobo zokunxiba ezikumgangatho ophezulu kunye netekhnoloji yobuchwephesha bokuqina komphezulu wevalvu ukubonelela ngezisombululo zeemeko ezinzima zokusebenza kwishishini lemichiza yamalahle..
