Izinkinga zokuguguleka kanye nezixazululo zevalvu kagesi Indlela yokusebenzisa i-valve kagesi ngokunembile

 
Mayelana nezinkinga kanye nezixazululo zamavalvu kagesi angaguguleki akhiqizwe ukuze kusetshenziswe imidiya egugulekayo, ingaphakathi lomzimba we-valve kanye nomgogodla webhola kufakwe i-ethylene evikela ukuguguleka kwe-polyperfluorinated, ngakho inokwethenjelwa ukumelana nokuguguleka nokuvala uphawu. impahla.

Ukuguguleka kwamakhemikhali ezinsimbi kuncike ezingeni lokushisa, umthwalo wemishini wezingxenye eziqhumayo, ubude besikhathi sokuxhumana phakathi kwe-sulfide equkethwe ezintweni zokugcoba kanye nokumelana ne-asidi yayo kanye nendawo, umphumela we-catalytic wensimbi kwinqubo ye-nitridation, izinga lokuguqulwa kwama-molecule ezinto ezigugulekayo zibe yinsimbi nokunye.

1. Ukuguguleka kwe-valve kagesi ngokuvamile kuqondwa njengokucekelwa phansi kwezinto zensimbi ze-valve kagesi ngaphansi kwesenzo samakhemikhali noma imvelo ye-electrochemical. Ngenxa yokuthi ukuguguleka kwenzeka ekusebenzelaneni okuzenzakalelayo phakathi kwezinsimbi nendawo ezungezile, indlela yokuhlukanisa izinsimbi endaweni ezungezile noma ukusebenzisa izinto zokwenziwa ezingezona ezensimbi sekuyinkinga evamile kubantu.

2. Njengoba kwaziwa yibo bonke, ukuguguleka kwensimbi nokucekelwa phansi kunomthelela omkhulu empilweni yesevisi, ukwethembeka kanye nempilo yesevisi yama-valve kagesi. Izici zemishini nokuguguleka ezisebenza ensimbi zikhuphula inani eliphelele lokuguga endaweni yokuxhumana. I-valve kagesi ngesikhathi sokusebenza, ukuguga okuphelele kobuso bokungqubuzana. Ngesikhathi sokusebenza kwe-valve kagesi, indawo yokushayisana iyagqokwa futhi ilimale ngenxa yesenzo somshini kanyekanye nokusebenzisana kwamakhemikhali noma kwe-electrochemical phakathi kwensimbi nendawo ezungezile. Ku-valve kagesi, indawo yezulu yepayipi yokusebenza iyinkimbinkimbi; Ukukhuphuka kwe-hydrogen sulfide, i-carbon dioxide kanye namanye ama-asidi e-organic ku-petroleum, igesi yemvelo kanye ne-oyela yokugcina amanzi kwandisa amandla abhubhisayo endaweni yensimbi, ngaleyo ndlela alahlekelwe amandla okusebenza ngokushesha.

3, ngoba ukuguguleka kwamakhemikhali ensimbi kuncike ezingeni lokushisa, umthwalo wemishini wezingxenye zokungqubuzana, i-sulfide equkethwe ezintweni zokugcoba kanye nokumelana ne-asidi yayo kanye nobude bokuxhumana obuphakathi kanye nomthelela wensimbi kwinqubo ye-nitriding, izinga lokuguqulwa kwama-molecule ezinto ezigugulekayo zibe yinsimbi nokunye. Ngakho-ke, indlela ye-anti-corrosion (noma izilinganiso) ye-valve kagesi yensimbi kanye nokusetshenziswa kwe-synthetic material valve kagesi ibe ngesinye sezihloko zocwaningo embonini yama-valve kagesi okwamanje.

I-4, i-valve kagesi yensimbi evimbela ukubola, ingaqondwa njenge-valve kagesi yensimbi ehlanganiswe nesisekelo sokuvikela ekugugulekeni (njengopende, upende, izinto zokugcoba, njll.), ukuze i-valve kagesi noma ngabe isekukhiqizeni, ekugcinweni, kwezokuthutha namanje kuyo yonke inqubo yokusetshenziswa kwayo ayiguguleka.

I-5, indlela yokunqanda ukubola kwe-valve kagesi yensimbi incike esimisweni sesikhathi sokuvikela, indawo yokuhamba kanye nokugcinwa, izici zesakhiwo se-valve kagesi nezinto zokwakha, yebo, ukuzivumelanisa nokubheka umphumela wezomnotho wokulwa nokugqwala.

Ama-valve kagesi kufanele asetshenziswe kanjani

Ukulawulwa kagesi kwe-valve kagesi ngenxa yenqubekela phambili eqhubekayo yezinga lezidingo ezishintshayo zezimboni, uhlangothi olulodwa lubhekene nokusetshenziswa kwama-valve kagesi amaningi, olunye uhlangothi lubhekene nezidingo zokulawula ama-valve kagesi ziya ngokuya ziba phezulu, ngaphezulu futhi more complex. Ngakho-ke ukuklanywa kwe-valve kagesi ekulawuleni ugesi nakho kubuyekezwa njalo. Ngokuthuthukiswa kwesayensi nobuchwepheshe kanye nokuthandwa kwekhompiyutha, izindlela ezintsha zokulawula ugesi zizoqhubeka nokukhuphuka. Ukuze kucatshangelwe ukulawulwa okuphelele kwe-valve kagesi, ukunakwa kufanele kukhokhwe ekukhethweni kwemodi yokulawula ye-valve kagesi. Isibonelo, ngokuya ngezidingo zephrojekthi, noma ngabe ukusebenzisa imodi yokulawula emaphakathi, kuseyimodi yokulawula eyodwa, noma ngabe ukuxhumanisa nezinye izinto zokusebenza, ukulawulwa kohlelo kusewukusetshenziswa kokulawulwa kohlelo lwekhompiyutha, nokunye, ukulawula kwayo. isimiso sihlukile. Isampula elinikezwe umkhiqizi wedivayisi kagesi ye-valve iyisimiso sokulawula ugesi esikalini, ngakho ingxenye yokusetshenziswa kufanele ibe ukudalulwa kobuchwepheshe nomkhiqizi wedivayisi kagesi ukuze acacise izidingo zobuchwepheshe. Ngaphezu kwalokho, lapho sikhetha ama-valve kagesi, kufanele sicabangele ukuthi sithenge isilawuli se-valve eyengeziwe kagesi. Ngokuvamile, isilawuli sithengwa ngokwehlukana. Ezimweni eziningi, uma usebenzisa isilawuli esisodwa, kuyadingeka ukuthenga isilawuli, ngoba ukuthengwa kwesilawuli kulula futhi kushibhile kunokuklama nokukhiqiza komsebenzisi. Lapho umsebenzi wokulawula ugesi ungakwazi ukuhlangabezana nezidingo zedizayini yobunjiniyela, kufanele udluliselwe embonini yokukhiqiza ukuze ulungise noma udizayine kabusha.

Ngokwezidingo zokulawula ubunjiniyela, umsebenzi wokulawula we-valve kagesi ugcwaliswa yidivayisi kagesi. Inhloso yokusebenzisa i-valve kagesi iwukuvula, ukuvala nokulungisa ukuxhumana kwe-valve ukuze kuzuzwe isilawuli sikagesi esingesona esokwenziwa noma isilawuli sekhompyutha. Ukusetshenziswa kwamanje kwemishini kagesi akukhona nje ukonga abasebenzi. Ngenxa yokuthi umsebenzi kanye nekhwalithi yemikhiqizo yabakhiqizi abahlukene ihlukile, ngakho-ke, ukukhethwa kwamadivayisi kagesi nokukhethwa kwama-valve kubalulekile ekulinganeni kobunjiniyela.

Ebunjiniyela bamapayipi, ukukhethwa okunembile kwama-valve kagesi kungenye yezinto ezidingekayo ukuze kuhlangatshezwane nezidingo zokusetshenziswa. Uma i-valve kagesi esetshenzisiwe ingakhethiwe kahle, ngeke ithinte ukusetshenziswa, kodwa futhi ilethe imiphumela emibi noma ukulahlekelwa okukhulu. Ngakho-ke, i-valve kagesi kufanele ikhethwe ngokunembile ekwakhiweni kobunjiniyela bamapayipi. Ngaphandle kwemingcele yepayipi, i-valve kagesi kufanele inake ngokukhethekile indawo ezungezile yomsebenzi wayo. Ngenxa yokuthi idivayisi kagesi ku-valve kagesi iyimishini yemishini nekagesi, isimo sayo sokusebenza sithinteka kakhulu endaweni yayo yokusebenza.

Ngokuvamile, i-valve kagesi isendaweni yokusebenza elandelayo:

1. Ukufakwa kwangaphakathi noma ukusetshenziswa kwangaphandle ngezinyathelo zokuzivikela;

2, ukufakwa kwangaphandle, umoya, isihlabathi, imvula, ukukhanya kwelanga nokunye ukugqwala;

3, enegesi evuthayo, eqhumayo noma indawo yothuli;

4, indawo eshisayo neswakeme, indawo eshisayo eshisayo;

5, izinga lokushisa eliphakathi nendawo lepayipi liphezulu njenge-480 ℃ noma ngaphezulu;

6, izinga lokushisa elizungezile lingaphansi kuka -20 ℃;

7. Kulula ukugcwala noma ukucwiliswa emanzini;

8, ngezinto ezikhipha imisebe (izitshalo zamandla enuzi nemishini yokuhlola impahla ekhipha imisebe) imvelo;

9. Imvelo emkhunjini noma echwebeni (ngesifutho sikasawoti, isikhunta, esimanzi);

10, ngezikhathi zokudlidliza ezinobudlova;

11, othambekele ezikhathini zomlilo; Ku-valve kagesi endaweni engenhla, isakhiwo sayo sedivayisi kagesi, izinto zokwakha kanye nezinyathelo zokuzivikela zihlukile. Ngakho-ke, idivayisi kagesi ye-valve ehambisanayo kufanele ikhethwe ngokusho kwendawo yokusebenza engenhla.
