DN20 Ulawulo Lwesandla Oluhlala Njalo I-Titanium Globe Valve

I-DN20 Dual Manual Control Titanium I-Globe Valve iyivalvu eqinile eyenzelwe ukulawula okunembayo ukuhamba kwezinto eziwuketshezi noma eziwuketshezi ezindaweni eziyimboni ezidingayo. Yakhelwe nge-titanium esezingeni eliphezulu, le vivalvu inikeza ukumelana okuhle nokugqwala nokuklebhula, okuyenza ilungele ukusetshenziswa ezindaweni ezinzima. Isici sokulawula okubili okwenziwa ngesandla sivumela ukulungiswa okunembayo kokuqina kokugeleza kusuka kuzo zombili iziphetho zevalvu, okuvumela ukunemba okuthuthukisiwe nokuguquguquka ekulawuleni ukuhamba kwezinto eziwuketshezi noma eziwuketshezi.

Ukwethula ukusetshenziswa kwe- i-titanium alloy kumavalvu omkhumbi, futhi nikeza isibonelo se- I-Titanium Alloy Globe Valve ukuchaza izici eziyinhloko zokwakheka, ukuklama nokubalwa kwezinto zokubopha kanye nokusebenza kwamandla kwe- I-Titanium Alloy Gate Valve. Ukunaka ukugqwala kwayo kukagesi emanzini olwandle nezindaba ekukhiqizeni, ukukhombisa ukuthi i-Ti ne-titanium alloy zinezinzuzo ezicacile zesisindo esikhanyayo, amandla aphezulu nokumelana nokugqwala njll. kanye nobubanzi obukhulu bamathuba okusetshenziswa emikhunjini nasezobunjiniyela bolwandle.

Amavalvu e-Titanium kanye nezingxubevange ze-titanium ezinesisindo esikhanyayo, amandla aphezulu, ukumelana nokugqwala, ukumelana nomfutho omuhle nezinye izinzuzo ezivelele, manje zisetshenziswa kabanzi kwezindiza, ukuthuthukiswa kwezindiza, upetroliymu, imboni yamakhimikhali, imetallurgy, ugesi, imithi nempilo, izinto zokulinganisa nezinye izimboni. Ukuze kuhlangatshezwane nezidingo zemikhumbi ejulile yobunjiniyela bezilwandle, imikhumbi, amavalvu olwandle nezinye izindawo, inethiwekhi yobuchwepheshe bamavalvu izosebenzisa izingxubevange zayo ze-titanium ekwenzeni amavalvu, amavalvu e-titanium enqubeni yokuthuthukiswa, ngobuchwepheshe obusha, izinto ezintsha namazinga amasha ukulawula ukwakhiwa kwemikhiqizo, ngokuhambisana nezidingo zenqubomgomo kazwelonke yemikhiqizo ye-high-tech, ubuchwepheshe obusakhula, futhi obunethembisa bokusebenzisa izinto, ngaleyo ndlela kuthuthukiswe ikhwalithi yamavalvu, kuthuthukiswe ukusebenza komkhiqizo!

Ukumelana nokugqwala kwe-titanium

Impahla ye-Titanium iyinsimbi esebenza kakhulu ngokwemvelo, kodwa-ke, ibonisa ukumelana okuhle kakhulu nokugqwala ezindabeni eziningi ezonakalisa. Isizathu salokhu ukuthi i-titanium inokufana okukhulu ne-oksijeni, futhi lapho i-titanium ivezwa emoyeni, noma kunoma yiluphi uhlobo lwe-oksijeni oluphathwayo, ifilimu eliqinile neligoqekile le-oxidizing elenziwe ngokushesha liyakheka ebusweni. Leli filimu lizinzile kakhulu, futhi uma kwenzeka ukulimala komshini, lizovuselelwa ngokushesha (uma nje kukhona inani elithile le-oksijeni).
Insipho ye-Titanium inezinhlobo eziningana ezikhethekile zokugqwala, njengokugqwala kwezinga lokushisa eliphezulu, ukugqwala kokucindezeleka, ukugqwala kwe-pitting, ukugqwala kwe-crevice, ukugqwala kwe-galvanic coupling, ukukhathala kokugqwala, njll., kodwa i-titanium esetshenziswa emivalweni yasolwandle ikakhulukazi ikhathazwa ukugqwala kwe-galvanic coupling.
Ukugqwala okubangelwa ukuxhumana kwe-galvanic kwenzeka lapho izinsimbi ezimbili ezihlukene esikhungweni esikagesi zakha isibhangana se-galvanic, njengoba i-anode yensimbi yokugqwala ingashesha. Ubungako bokugqwala buya ngokuya ngomkhawulo we-electrode phakathi kwezinto ezimbili, kodwa futhi buya ngokuya ngesilinganiso sendawo ye-anode ne-cathode kanye nezici ze-polarization zazo zombili. I-Titanium ihlukile kwezinto ezijwayelekile ngoba iyasebenza emithonjeni eminingi futhi ibonisa umkhawulo ofana nowensimbi engagqwali ye-18-8. Umkhawulo we-titanium emanzini olwandle ngu-0.10V (ama-electrode we-calomel agcwele). I-Titanium esebenza nezingxubevange ze-Monel, i-Hastelloy C, insimbi engagqwali ye-18-8, namashidi amapayipi e-aluminum-bronze anengeziwe i-Ni inomkhawulo omncane kakhulu futhi ayikhiqizi ukugqwala kwe-galvanic coupling. Kodwa-ke, nasemanzini olwandle, lapho i-titanium isebenza ne-aluminum, i-zinc, nensimbi ye-carbon, i-aluminum ne-zinc ziyagqwala. Kodwa-ke, izinga lazo lokugqwala lincane kunezingqwala ezibangelwa ukusebenza ne-stainless steel. Ubungako bokugqwala kwezinsimbi buya ngokuya ngesilinganiso sendawo ye-titanium kuye kweyensimbi esebenza ne-titanium. Lapho isilinganiso sendawo yensimbi esebenza ne-titanium kuye kweye-titanium singu-1:10 (okungukuthi, isilinganiso sendawo ye-anode kuye kweye-cathode singu-1:10), insimbi esebenza nayo iyagqwala ngokushesha. Ngokuphambene, lapho isilinganiso sendawo yensimbi esebenza ne-titanium ne-titanium singu-10:1, izinga lokugqwala liyancipha kakhulu.
