Amavalvu Alawula Ukugeleza Kwe-Piston
Izici
▪ Ukulawulwa komugqa: ukuvuleka nokugeleza kwevalvu kumugqa, okwazi ukubona ukulawulwa okunembile.
▪ Izindleko eziphansi zokunakekela kanye nempilo ende yesevisi: umgudu wokugeleza onengqondo nokukhethwa kwezinto ezifanele kuqinisekisa impilo ende yesevisi yevalvu.
▪ Amandla amancane okushayela: idizayini yebhalansi ye-hydraulic, ehambisana nomugqa okhombisa ingxube yethusi ukuze kuqinisekiswe ukuthi ipiston isebenza ngokuzinza nangokuthembekile.
▪ Ukufakwa ngokuzithandela: ivalvu ingafakwa iqonde phezulu, ivundlile futhi imiswe, noma nhlangothi zombili zepayipi.
▪ Ukuvalwa okuthembekile (uhlobo oluvamile): ukwakheka okukhethekile kwe-valve ye-elastomer;Isihlalo se-valve yensimbi esixhunywe nejeli ye-silica elastic esebenza kahle kakhulu sinikeza umphumela wokuvala izinga lebhamuza, sivimbele ngempumelelo isihlalo se-valve ukuthi singaklwebheki futhi sandise impilo yesevisi yesihlalo se-valve.
▪ Ukushabalalisa amandla okushayisana kanye nokudlidliza (uhlobo lwama-orifice amaningi).
Idizayini yezimbobo eziqinile, i-anti cavitation (uhlobo lwama-orifice amaningi).
▪ Isetshenziselwa izinjongo eziningi futhi ingangena esikhundleni sevalvu yokulawula i-diaphragm ye-hydraulic kanye ne-Y-type control valve.
▪ Imodi yokusebenza: ukusebenza kwe-hydraulic cylinder, ukusebenza kukagesi kagesi, ukusebenza kwegiya lezikelemu okwenziwa ngesandla kanye nokusebenza kwegumbi lokulawula kude.
▪ Ukusebenzisa imisebenzi: ukulawula ukugeleza, ukulawula ukunciphisa ingcindezi, ukulawula ukubamba ingcindezi, ukulawula ukulawula ingcindezi, ukubamba ingcindezi nokulawula ukunciphisa ingcindezi.
Ukucaciswa Kwempahla
| Ingxenye | Okubalulekile |
| Umzimba | I-Ductile cast iron |
| Indandatho Yesihlalo | I-SUS304 |
| Isiqu | I-SUS410 |
| Indandatho yokuvala | I-NBR |
| Ibholithi Yangaphakathi | I-SUS304 |
| I-Trust Bearing | I-SUS304 |
| Ezinye izinto ezidingekayo zingaxoxisana. |
Isakhiwo
Isimiso Sokusebenza
▪ Ivalvu yokulawula i-piston yakhiwa kakhulu umzimba wevalvu, isihlalo sevalvu, i-piston, i-valve shaft, i-crank, induku yokuxhuma, iphini lokushayela, iphini lokuphusha, i-bearing kanye nendlela yokusebenza.
▪ Ivalvu elawula i-piston iguqula ukuzungeza kwe-valve shaft ibe i-axial movement ye-piston eduze nomzila wesitimela ngomshini wokuxhuma we-crank.Enqubweni ye-piston ehamba phambili naphambili, ukulawulwa kokugeleza nokulawula ukucindezela kubonakala ngokushintsha indawo yokugeleza phakathi kwepiston nesihlalo se-valve.
Amanzi ageleza ku-valve emzimbeni esuka ku-axial arc.Ishaneli yokugeleza ku-valve yokulawula i-piston i-axisymmetric, futhi ngeke kube khona ukuphazamiseka lapho uketshezi lugeleza.
▪ Kungakhathaliseki ukuthi ipiston inyakaza kuphi, ingxenye yokugeleza kwamanzi egunjini le-valve kunoma iyiphi indawo iba yi-annular futhi ishwabana iye e-axis ekuphumeni kwayo, ukuze kuzuzwe i-anti cavitation engcono kakhulu futhi kugwenywe ukulimala emzimbeni we-valve kanye nepayipi elibangelwa cavitation ngenxa throttling.
