Iingxaki zokhukuliseko kunye nezisombululo zevalve yombane Indlela yokusebenzisa ivalve yombane ngokuchanekileyo

 
Ngokweengxaki kunye nezisombululo zeevalvu zombane ezinganyangekiyo kukhukuliseko eziveliswe kwimithombo yeendaba ezikhukulisekayo, umngxuma ongaphakathi womzimba wevalve kunye nombindi webhola ufakwe i-ethylene enganyangekiyo kukhukuliseko kunye nobudala, ngenxa yoko inokumelana nokhukuliseko oluthembekileyo kunye nokutywinwa. impahla.

Ukhukuliseko lweekhemikhali zesinyithi luxhomekeke kwiqondo lobushushu, umthwalo womatshini wamacandelo abrasive, ixesha loqhagamshelwano phakathi kwesulfide equlethwe kwizinto zokuthambisa kunye nokuxhathisa kwayo ngeasidi kunye nephakathi, impembelelo yesinyithi kwinkqubo ye-nitridation, izinga lokuguqulwa kweemolekyuli zezinto ezikhukhulayo kwintsimbi kunye nokunye.

1. Ukukhukuliseka kwevalve yombane ngokuqhelekileyo kuqondwa njengokutshatyalaliswa kwezinto zetsimbi zevalve yombane phantsi kwesenzo sekhemikhali okanye i-electrochemical environment. Ngenxa yokuba ukhukuliseko lwenzeka kunxibelelwano oluzenzekelayo phakathi kwesinyithi kunye nokusingqongileyo okungqongileyo, indlela yokwahlula isinyithi kwindawo engqongileyo okanye ukusebenzisa imathiriyeli engaphezulu engeyiyo eyentsimbi iye yaba yinkxalabo eqhelekileyo ebantwini.

2. Njengoko kwaziwa kubo bonke, ukuguguleka kwesinyithi kunye nokutshatyalaliswa kunempembelelo enkulu kubomi benkonzo, ukuthembeka kunye nobomi benkonzo yee-valve zombane. Izinto zoomatshini kunye nokukhukuliseka okusebenzayo kwisinyithi kwandisa inani elipheleleyo lokunxiba kwindawo yoqhagamshelwano. Ivalve yombane kwinkqubo yokusebenza, i-friction surface total wear. Ngethuba lokusebenza kwe-valve yombane, i-friction surface igugile kwaye yonakaliswe ngenxa yesenzo soomatshini kunye neekhemikhali okanye ukusebenzisana kwe-electrochemical phakathi kwesinyithi kunye nokusingqongileyo. Kwivalve yombane, indawo yokusebenzela yombhobho inzima; Ukunyuka kwe-hydrogen sulfide, i-carbon dioxide kunye nezinye i-asidi ze-organic kwi-petroleum, igesi yendalo kunye ne-oyile yokugcina amanzi kwandisa amandla okutshabalalisa umphezulu wesinyithi, ngaloo ndlela ulahlekelwa ngokukhawuleza ukukwazi ukusebenza.

3, ngenxa yokuba ukhukuliseko lweekhemikhali zesinyithi luxhomekeke kwiqondo lobushushu, umthwalo womatshini weendawo zokukhuhlana, i-sulfide equlethwe kwizinto zokuthambisa kunye nokumelana ne-asidi kunye nobude obuphakathi bokunxibelelana kunye nefuthe lesinyithi kwinkqubo ye-nitriding, izinga lokuguqulwa kweemolekyuli zezinto ezikhukhulayo kwintsimbi kunye nokunye. Ngoko ke, indlela yokulwa ne-corrosion (okanye imilinganiselo) yevalve yombane yentsimbi kunye nokusetyenziswa kwe-synthetic material valve yombane ibe yenye yezihloko zophando kwishishini le-valve yombane okwangoku.

I-4, i-valve yentsimbi yombane ye-anticorrosion, inokuqondwa njenge-valve yesinyithi yombane efakwe kwindawo yokukhusela ekukhukulisekeni (okufana nepeyinti, ipeyinti, izinto zokuthambisa, njl. kusekuyo yonke inkqubo yokusetyenziswa kwayo ayikakhukuliseka.

I-5, indlela ye-valve yombane yensimbi ye-anticorrosion ixhomekeke kwimfuno yexesha lokukhusela, ukuthutha kunye nokugcinwa kwendawo, iimpawu zesakhiwo sevalve yombane kunye nezinto eziphathekayo, ngokuqinisekileyo, ukulungelelanisa ukuqwalasela umphumo wezoqoqosho wokulwa nokubola.

Kufuneka zisetyenziswe njani kanye iivalvu zombane

Ukulawulwa kombane kwevalve yombane ngenxa yenkqubela phambili eqhubekayo yenqanaba leemfuno ze-automation ye-industrial, elinye icala lijongene nokusetyenziswa kweevalvu zombane ngakumbi nangakumbi, elinye icala lijongene neemfuno zolawulo lweevalvu zombane ziba phezulu nangaphezulu, ngaphezulu kwaye nzima ngakumbi. Ngoko uyilo lwevalve yombane kulawulo lombane nalo luhlaziywa rhoqo. Ngokuphuculwa kwesayensi kunye nobuchwepheshe kunye nokuthandwa kwekhompyuter, iindlela ezintsha kunye neendlela ezahlukeneyo zokulawula umbane ziya kuqhubeka nokunyuka. Ukuqwalasela ulawulo olupheleleyo lwe-valve yombane, ingqalelo kufuneka ihlawulwe ekukhethweni kwendlela yokulawula i-valve yombane. Umzekelo, ngokweemfuno zeprojekthi, nokuba kusetyenziswe imowudi yolawulo oluphakathi, kuseyimowudi yolawulo enye, nokuba ukudibanisa nezinye izixhobo, ulawulo lwenkqubo luselusetyenziso lolawulo lwenkqubo yekhompyuter, njalo njalo, ulawulo lwayo. umgaqo wahlukile. Isampulu enikwe ngumenzi wesixhobo sombane sisikali somgaqo wolawulo lombane, ngoko ke inxalenye yosetyenziso kufuneka ibe lubhengezo lobugcisa kunye nomvelisi wesixhobo sombane ukucacisa iimfuno zobugcisa. Ukongezelela, xa ukhetha iivalve zombane, kufuneka sicinge ukuba sithenge isilawuli esongezelelweyo sombane. Ngokubanzi, umlawuli uthengwa ngokwahlukileyo. Kwiimeko ezininzi, xa usebenzisa ulawulo olulodwa, kuyimfuneko ukuthenga isilawuli, kuba ukuthengwa kwesilawuli kulula kwaye kungabizi ngaphezu koyilo lomsebenzisi kunye nokuvelisa. Xa umsebenzi wokulawula umbane awukwazi ukuhlangabezana neemfuno zoyilo lobunjineli, kufuneka ubekwe phambili kwisityalo sokuvelisa ukuguqula okanye ukuyila kwakhona.

Ngokweemfuno zokulawula ubunjineli, umsebenzi wokulawula i-valve yombane ugqitywe ngesixhobo sombane. Injongo yokusebenzisa ivalve yombane kukuvula, ukuvala kunye nokulungelelanisa uqhagamshelwano lwevalve ukuze kuphunyezwe ulawulo lombane olungelolwamvelo okanye ulawulo lwekhompyutha. Ukusetyenziswa kwangoku kwezixhobo zombane ayikokugcina nje abasebenzi. Ngenxa yokuba umsebenzi kunye nomgangatho weemveliso zabakhiqizi abahlukeneyo bahluke, ngoko ke, ukukhethwa kwezixhobo zombane kunye nokukhethwa kweevalve kubalulekile ekulinganeni kobunjineli.

Kubunjineli bemibhobho, ukhetho oluchanekileyo lwee-valve zombane ngenye yezinto ezifunekayo ukuhlangabezana neemfuno zokusetyenziswa. Ukuba i-valve yombane esetyenzisiweyo ayikhethwanga ngokufanelekileyo, ayiyi kuchaphazela ukusetyenziswa, kodwa iphinde izise imiphumo emibi okanye ilahleko ezinzima. Ngoko ke, i-valve yombane kufuneka ikhethwe ngokuchanekileyo kuyilo lobunjineli bombhobho. Ukongeza kwiiparamitha zombhobho, i-valve yombane kufuneka ihlawule ngokukhethekileyo indawo engqongileyo yomsebenzi wayo. Ngenxa yokuba isixhobo sombane kwi-valve yombane sisixhobo somatshini kunye nombane, imeko yayo yokusebenza ichaphazeleka kakhulu kwindawo yayo yokusebenza.

Ngokuqhelekileyo, ivalve yombane ikule meko ilandelayo yokusebenza:

1. Ufakelo lwangaphakathi okanye ukusetyenziswa kwangaphandle ngamanyathelo okukhusela;

2, ukufakwa kwangaphandle, umoya, isanti, imvula, ilanga kunye nokunye ukubola;

3, enerhasi enokutsha, eqhumayo okanye indawo engqongileyo yothuli;

4, indawo eshushu nefumileyo, indawo eyomileyo yetropiki;

5, ubushushu bombhobho ophakathi buphezulu ukuya kuma-480℃ okanye ngaphezulu;

6, ubushushu be-ambient bungaphantsi kwe-20℃;

7. Kulula ukukhukuliswa okanye ukuntywiliselwa emanzini;

8, ngezinto ezineradioactive (amaziko amandla enyukliya kunye nezixhobo zokuvavanya imathiriyeli yeradioactive) okusingqongileyo;

9. Imeko engqongileyo kwinqanawa okanye kwidokhi (ngetyuwa yokutshiza, isikhunta, imanzi);

10, kunye neziganeko zokungcangcazela ezinobundlobongela;

11, kumathuba omlilo; Kwi-valve yombane kule ndawo ingentla, isakhiwo sayo sombane, izixhobo kunye namanyathelo okukhusela ahlukeneyo. Ke ngoko, isixhobo sombane sevalve ehambelanayo kufuneka sikhethwe ngokwendawo yokusebenza engentla.
