Valve mbishi zvinhu senge oiri yedunhu ndiro, imwe yekuyerera vharafu uye piston vharafu zvinounzwa zvakadzama

Valve zvigadzirwa zvakaita sendiro yemafuta edunhu, imwe inoyerera vharafu uye piston vharafu inounzwa zvakadzama Oiri redunhu ndiro, imwe inoyerera vharafu uye gedhi vharafu (piston vharafu) chimwe chezvikamu zvakakosha zvevhavha, nekukurumidza tora yepakati kushanda kumanikidza, zvinowanzo shandiswa mbishi zvinhu zvinofanirwa kusangana nezvinodiwa zve "valve pressure uye tembiricha level". Carbon simbi: Inokodzera zita rekumanikidza PN≤32.0MPa, tembiricha -30 ~ 425 ℃ mvura, chiutsi, gasi, hydrogen, ammonia, nitrogen uye petroleum zvigadzirwa uye mamwe midhiya. Common mamakisi WC1, WCB, ZG25 uye mhando simbi 20, 25, 30 uye yakaderera alloy simbi 16Mn. Stainless acid inodzivirira simbi, inokodzera zita rekumanikidza PN≤6.4Mpa, tembiricha ≤200℃ sodium cyanide, glacial acetic acid uye mamwe midhiya... Zvizhinji zvekugadzira nekugadzira zvikamu zvevharuvhu, zvinosanganisira mhando dzakasiyana dzechiedza. simbi nesimbi dzinokosha uye aruminiyamu alloy, zvakasiyana-siyana zvisiri zvesimbi. Raw zvinhu zvekugadzira mavharuvhu zvikamu zvinofanirwa kusarudzwa zvinoenderana nezvinotevera zvinhu: 1, kushanda yepakati kudzvanywa, tembiricha uye maitiro. 2, iyo inotakura simba yezvikamu uye inowanzoita basa muchimiro chevharuvhu. 3. Good process performance. 4. Pasi pechikonzero chekusangana nemamiriro ezvinhu ari pamusoro apa, mari yakaderera inodiwa. Raw zvinhu zveoiri redunhu ndiro, imwe inoyerera vharafu uye vharafu ndiro (piston vharafu) Oiri redunhu ndiro, imwe yekuyerera vharafu uye gedhi vharafu (piston vharafu) chimwe chezvikamu zvakakosha zvevhavha, nekukurumidza tora iyo yepakati kushanda kumanikidza, inowanzoshandiswa. zvigadzirwa zvinofanirwa kusangana nezvinodiwa zve "valve pressure uye tembiricha level". Zvishandiso zvakajairika zvinowira muzvikamu zvinotevera: 1, grey cast iron: grey cast iron inokodzera zita rekumanikidza PN≤1.0MPa, tembiricha -10 ℃ ~ 200 ℃ mvura, chiutsi, gasi, liquefied gasi uye mafuta akacheneswa uye mamwe midhiya. Gray cast iron yakajairika giredhi: HT200, HT250, HT300, HT350. Zviviri, simbi inoumbwa: inokodzera zita rekumanikidza PN≤2.5MPa, tembiricha -30 ~ 300 ℃ mvura, chiutsi, gasi uye svikiro remafuta, mhando dzakajairika ndeidzi: KTH300-06, KTH330-08, KTH350-10. Tatu, ductile kukanda: yakakodzera PN≤4.0MPa, tembiricha -30 ~ 350 ℃ mvura, chiutsi, gasi uye mafuta uye mamwe midhiya. Marudzi akajairika ndeaya: QT400 -- 15, QT450 -- 10, QT500 -- 7. Nekuda kwedanho remazuva ano tekinoroji yenyika yedu, mafekitori akanaka uye mamwe akaipa uye vatengi havasi nyore kuona. Maererano nezvakaitika, zvinokurudzirwa kuti PN≤2.5MPa, valve kana simbi valve inosarudzwa kuti ichengetedze. Ina, asidhi inopikisa yakakwira silicon ductile kukanda: inokodzera zita rekumanikidza PN≤0.25MPa, tembiricha isingasviki 120 ℃ inoparadza svikiro. shanu, kabhoni simbi: inokodzera zita rekumanikidza PN≤32.0MPa, tembiricha -30 ~ 425 ℃ mvura, chiutsi, gasi, hydrogen, ammonia, nitrogen uye petroleum zvigadzirwa uye mamwe midhiya. Common mamakisi WC1, WCB, ZG25 uye mhando simbi 20, 25, 30 uye yakaderera alloy simbi 16Mn. Vi. Alloy zvinhu: Inokodzera PN≤2.5MPa mvura, gungwa, O2, gasi, oiri uye mamwe midhiya, uye tembiricha ye -40 ~ 50 ℃ vapor medium, zvakajairika mabhureki ZGnSn10Zn2 (tin bronze), H62, HPB59-1 (tsvuku mhangura), Qaz19-2, Qa19-4 (aluminum bronze). Zvinomwe, zvinoramba zvichikwira tembiricha mhangura: inokodzera zita rekumanikidza PN≤17.0MPA, tembiricha ≤570 ℃ yekudziya kwehutsi uye zvigadzirwa zvepetroleum. Yakajairika mhando ine ZGCr5Mo, 1 cr5m0. ZG20CrMoV, ZG15Gr1Mo1V, 12 crmov WC6, WC9, etc. Iko kushandiswa kwechokwadi kunofanira kunge kunoenderana nekumanikidzwa kwevhavha uye tembiricha yekumisa zvinodiwa. Eight, yakaderera tembiricha simbi, yakakodzera zita kudzvanywa PN≤6.4Mpa, tembiricha ≥ -196 ℃ butadiene, pe, mvura chaiyo gasi, liquid nitrogen uye mamwe midhiya, zvakajairika mhando) vari ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18 Ni9 Tikisi, ZG0Cr18 simbi, inokodzera zita rekumanikidza PN≤6.4Mpa, tembiricha ≤200 ℃ sodium cyanide, acetic acid uye mamwe midhiya, akajairika mabhureki ndeye ZG0Cr18Ni9Ti, ZG0Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, acid kuramba uye urea mhinduro Iyo yekupedzisira dhayamita yekukanganisa yedhisiki yemahara inodzorwa nekuda kwehupamhi uye kumucheto deformation yemhangura uye alloy simbi castings yevhavha mbishi zvinhu, saka hapana kushivirira kwedimensional kunodiwa. Mutengesi uye odha yekuisa usati watenga zvinhu, kana huwandu hwechigadzirwa chakadaro chakamisikidzwa machining zvakasara. Mabhureki anokonzerwa neakakasharara mupendero, kubaya nhengo, punching muchina, kana kupfuura pamusoro peiyo dhizaini yekufa kwekufa kunobvumidzwa chero bedzi ichibviswa panguva yekugadzira kana isingakuvadzi kuramba iri muchigadzirwa chakapedzwa (G1, G2, G3, uye G4 muFIG 9). Dhirowa inofanira kuratidza kuti mipendero yakadaro haifanire kudarika 1.5 mm Kubatanidza: Simbi inokandwa yemhangura uye alloy zvinhu zvevharuvhu zvigadzirwa (II) Dimensional kukanganisa mukati nekuyambuka kufa - mitsara yekuparadzanisa Raw material boka I, tsanangudzo, uye t inofanira kuenderana kutsauka kwemhando yakapihwa muTafura 14, nepo mbishi boka rezvinhu Ⅱ richifanira kuenderana neTafura 15, mbishi boka boka Ⅲ Iyo yakakura kududzirwa kwecalcination Angle, tmax, ndiyo chiyero cheiyo inowanikwa dimensional kushivirira pane iyo yakatarwa t yemutsara wekuparadzanisa. Iko kukanganisa kwetmax kuri munzvimbo yekusimudzira A yeakaomesesa kurova Angle yechikamu. Muchiitiko chezvikamu zvegore, nzvimbo yose A yakaenzana nenharaunda yeA denderedzwa; muchiitiko chezvikamu zvisina kukwana, nzvimbo yose A yakaenzana nenharaunda yekunze yakachekwa rectangle (ona Mufananidzo 4). Zvese zvidiki zvakatemwa zvine chikanganiso chakafanana netmax.
