Iqhaza elibalulekile lamavalvu akhipha anwebekayo akhuphukayo naphansi ekulawuleni inqubo yamakhemikhali
Emkhakheni wokulawula inqubo yamakhemikhali, ukulawula uketshezi olunembile kuyisihluthulelo sokuqinisekisa ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza. Njengengxenye ebalulekile yesistimu yokulawula inqubo, ama-valve okukhipha ukunwetshwa okukhuphukayo naphansi ahlinzeka ngesixazululo sokulawula ukugeleza okuthembekile kakhulu. Lesi sihloko sizohlola izindima ezibalulekile ezidlalwa yilezi zinhlobo ezimbili zama-valve okukhipha ekulawuleni inqubo yamakhemikhali.
Ukulawula ukugeleza nokusebenza kokuvala
Idizayini eyingqayizivele yamavalvu akhipha anwebekayo akhuphukayo naphansi yenza uvuleke ngokushesha futhi uvale, okubalulekile ezinqubweni zamakhemikhali ezidinga ukushintshwa njalo. Ngokuvamile zifakwe ama-actuator we-pneumatic noma hydraulic, angafinyelela isilawuli kude futhi anikeze izindlela zokusebenza eziphephile nezilula kakhulu. Mayelana nokuvala, lawa ma-valve angavimbela noma yikuphi ukuvuza okuphakathi esimweni esivaliwe, ukuqinisekisa ukuqhubeka kwenqubo yamakhemikhali kanye nokuhlanzeka kwendawo ezungezile.
Ukuphathwa kahle kwezinto ezikhishwayo
Enqubweni yokukhiqiza amakhemikhali, kuvame ukudingekile ukwengeza noma ukususa izinto kureactor ngezikhathi ezithile. Ama-valve okukhipha akhuphukayo naphansi angakwazi ukuphendula ngokushesha emiyalweni yesistimu yokulawula futhi alawule ngokunembile ukuhamba kwezinto. Leli khono lokusabela ngokushesha libalulekile ekuvimbeleni izimo ezifana nokusabela okweqile noma okunganele, ngalokho kuqinisekisa ukusebenza kahle kokusabela kwamakhemikhali kanye nekhwalithi yemikhiqizo.
Ukusetshenziswa kwesikhala kanye nokuguquguquka kokufaka
Ngenxa yokuguquguquka komklamo, ama-valve okukhipha ukunwetshwa akhuphukayo naphansi angafakwa phezulu noma phansi kwepayipi ngokwezidingo zangempela, okuwenza afaneleke kakhulu ezimweni ezinendawo elinganiselwe. Lokhu kubaluleke kakhulu ezimbonini zamakhemikhali ezihleleke ngokuminyene, njengoba zivumela onjiniyela ukuthi bathuthukise ukwakheka kwemishini futhi banciphise ukusebenza kwendawo elinganiselwe.
Ububanzi bohlelo lokusebenza oluhlukahlukene
Amavalvu okukhipha anwebekayo aphezulu naphansi angasetshenziswa ukuphatha amakhemikhali ahlukahlukene, okuhlanganisa ukubola, i-viscosity ephezulu, noma imidiya equkethe izinhlayiya eziqinile. Ngokwezidingo ezihlukene zohlelo lokusebenza, izinto zokwakha zomzimba we-valve kanye ne-valve core zingenziwa ngokwezifiso, njengokusebenzisa insimbi engagqwali, i-Hastelloy alloy noma amanye ama-alloys akhethekile, kanye nerabha noma i-PTFE (i-polytetrafluoroethylene) njengezinto zokuvala ukuze zivumelane nemidiya yamakhemikhali ehlukene. kanye nezindawo zokusebenza.
Ukuvikeleka kanye Nokuvikelwa Kwemvelo
Embonini yamakhemikhali, ukuphepha nokuvikelwa kwemvelo yizindaba ezimbili ezibalulekile ezingenakuzitshwa. Ukuklanywa kwama-valve okukhipha ukwanda okunwebekayo kuqinisekisa ukuthi izinto ezisetshenziswayo zingahlukaniswa ngokushesha ezimeni eziphuthumayo, kuvinjwe izingozi ukuthi zenzeke. Ngaleso sikhathi, izici zabo zokuvuza okuyiziro zisiza ukunciphisa imithelela engaba khona emvelweni futhi zithobelane nemithetho eqinile yamanje yezemvelo.
Kafushane, ama-valve akhipha anwebekayo aphezulu naphansi adlala indima ebalulekile ekulawuleni inqubo yamakhemikhali. Abagcini nje ngokuhlinzeka ngezixazululo ezisebenzayo nezithembekile zokulawula ukugeleza, kodwa futhi zifaka isandla ekuvikelekeni nasekuvikelweni kwemvelo kokukhiqizwa kwamakhemikhali. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukusebenza kwala ma-valve akhiphayo kuzoqhubeka nokuthuthuka ukuze kuhlangatshezwane nezidingo ezikhulayo eziyinkimbinkimbi zemboni yamakhemikhali.
