Vavhavha vemukati vanoshanda munzvimbo dzinonetsa zvakanyanya, vakatarisana:
Kukukurwa kwevhu: Kunokonzerwa ne-high-velocity kana particle-laden fluid.
Corrosion: Kubva kumakemikari ane hukasha media.
Cavitation: Kuumbwa uye kudonha kwehuputi hwehuputi, zvichikonzera pasi pegomba.
High-Pressure / Tembiricha: Inotungamira kune galling (adhesive kupfeka) uye deformation.
Kuti urwise nyaya idzi, mavharuvhu emukati anowanzo gadzirwa kubva kana kuchengetedzwa nemidziyo yepamusoro, ine tungsten carbide iri sarudzo yepamusoro kune yakanyanya kuomarara masevhisi.
Iyi tafura inotevera inopfupisa yakajairwa mavharuvhu emukati, matambudziko avo, uye akajairwa zvinhu mhinduro:
| Chikamu | Function | Common Wear Mechanisms | Typical Material Solutions |
| Seat | Inopa nzvimbo yekuisa chisimbiso yekuvhara-kuvharwa. | Kukukurwa, Cavitation, Galling, Corrosion. | Tungsten Carbide, Stellite (Cobalt-Chrome), 316SS, Alloy 6, Ceramics. |
| Nhengo Yekuvhara (Plug/Disiki) | Inofamba kuvhura/kuvhara nzira yekuyerera. | Kukukurwa, Cavitation, Galling, Corrosion. | Tungsten Carbide, Stellite, 316SS, Hardened Steels. |
| Stem | Inotamisa mafambiro kubva ku actuator kuenda kunhengo yekuvhara. | Abrasion, Kuneta, Corrosion. | 17-4PH Stainless Simbi, Nitrided Steels, Corrosion-Resistant Alloys. |
| Cage | Inotungamira plug uye inodzora kuyerera maitiro. | Kukukurwa kwakanyanya, Cavitation, Noise/Vibration. | Tungsten Carbide, Stellite, 316SS, Duplex Stainless Steels. |
| Zvisimbiso & Gaskets | Inodzivirira kubuda kwekunze uye mukati. | Extrusion, Chemical Degradation, Heat Kuchembera. | PTFE (Teflon), Grafoil, Elastomers (Viton, EPDM). |
Nei Tungsten Carbide yeValve Yemukati?
Mumashandisirwo akaomarara anowanikwa mumafuta & gasi, kugadzirwa kwemagetsi, uye maindasitiri ekugadzira makemikari, tungsten carbide inotsanangurwa kune trim components nekuda kwayo:
Kunyanya Kuramba Kukukurwa kwevhu: Kumira jecha nezvimwe zvimedu zvakaoma murwizi rwemvura.
Yakanakisa Cavitation Resistance: Kuoma kwayo kunodzivirira kurasikirwa kwezvinhu kubva pakupinza mhute.
High Compressive Simba: Kuramba deformation pasi pekumanikidzwa kwakanyanya.
Good Galling Resistance: Kana yakabatanidzwa nechinhu chinowirirana, inoderedza njodzi yekubata.
Muchidimbu, Valve Internals ndiwo mwoyo wevhavha. Kusarudzwa kwavo, kunyanya kusarudzwa kwezvinhu zvinodzivirira kupfeka zvakadai tungsten carbide yezvikamu zvekucheka, isarudzo yakakosha yeinjiniya inotaridza zvakananga kushanda kwevharuvhu, hupenyu hwesevhisi, uye kuchengetedzwa kwese kwehurongwa mumamiriro ekushanda akaoma.
