Kukhona umehluko osobala phakathi kwama-valve esango lama-slide kanyeama-valve esango lommesengokuya ngesakhiwo, umsebenzi kanye nezimo zohlelo lokusebenza:

1. Ukuklama kwesakhiwo

Isango le-valve yesango elishelelayo liyisicaba, futhi indawo yokuvala ngokuvamile yenziwa nge-alloy eqinile noma irabha. Ukuvula nokuvala kufinyelelwa ngokuslayida okuvundlile kwesango eduze kwesihlalo se-valve. Isakhiwo siyinkimbinkimbi, futhi ukusebenza kokuvala kuncike ekunembeni okulingana phakathi kwesango nesihlalo se-valve.

Isango le-valve yesango lommese we-ductile iron lisesimweni se-blade, elingasika imicu, izinhlayiya nokunye ukungcola phakathi nendawo. Inesakhiwo esihlangene kakhudlwana. Indawo yokubeka uphawu phakathi kwesango nesihlalo se-valve iklanywe kakhulu njengokuxhumana kwensimbi eqinile, enokumelana okuqinile kokugqoka.

2. Ukusebenza kokubeka uphawu

I-valve yesango elishelelayo inomsebenzi omuhle wokuvala futhi ifaneleka ikakhulukazi izikhathi ezinezidingo zokuvuza okuphezulu (njengemithombo yegesi). Amanye amamodeli afakwe isakhiwo sokuvala kabili.

Ukuvalwa kwe-valve yesango lommese we-flange kugxile ekulweni nokugqokwa futhi kulungele imidiya equkethe izinhlayiya eziqinile, i-slurry, njll. Indawo yokuvala ingalungiswa ngokugaya, kodwa ukuvuza kukhulu kancane kunalokho kwe-valve yesango lepuleti lesilayidi.

3. Izimo Zokusebenza

Amavalvu esango elishelelayo asetshenziswa kakhulu ukuhlanza imidiya efana negesi kanye nemikhiqizo kawoyela, noma ezinhlelweni zamapayipi ezidinga ukuvalwa okuqinile.

I-valve yesango lommese enenjini ifaneleka kakhulu kumidiya equkethe ukungcola okufana nendle, i-pulp, nempushana yamalahle, futhi ivame ukusetshenziswa emikhakheni efana nensimbi, izimayini, nokuvikelwa kwemvelo.

I-Jinbin Valve igxile ekukhiqizeni nokwenza ngokwezifiso ama-valve esango lommese anobubanzi obukhulu. Ivalvu yesango lommese kasayizi omkhulu (onobubanzi obungu-≥DN300) asetshenziswa kakhulu kumapayipi ezimboni ngenxa yezinzuzo zawo zesakhiwo nokusebenza kwawo.

Ipuleti lesango elimise okwemmese lingakwazi ukusika kalula imicu, izinhlayiya noma izinto ezibonakalayo (ezifana ne-slurry, i-pulp) phakathi nendawo, ukuvimbela ukungcola ukuthi kuqoqwe futhi kuvimbe i-valve. Ifaneleka ngokukhethekile ukuthutha imidiya equkethe izinto eziqinile ezimisiwe, ukunciphisa imvamisa yokulungiswa kwamapayipi.

2. Umzimba we-valve wamukela umklamo oqondile, ohlanganisa ukumelana nokugeleza okuphansi kanye nokuvula okufushane nokuvala isango. Uma ihlanganiswe nama-actuator kagesi noma we-pneumatic, ingafinyelela ukuvulwa nokuvala ngokushesha, ukunciphisa ubunzima bokusebenza kwama-valve anobubanzi obukhulu futhi iyenze ifaneleke izimo zokulawula okuzenzakalelayo.

3. Izinto ezivalekayo ngokuvamile zenziwe nge-alloy eqinile noma insimbi engagugi engagugi, enokusebenza okuqinile kokuqeda ukuguguleka. Ngisho noma isetshenziswe isikhathi eside ngamazinga aphezulu okugeleza noma kumidiya equkethe izinhlayiya, ingagcina ukusebenza kahle kokuvala futhi inciphise izindleko zokushintshwa.

4. Umzimba we-valve unesakhiwo esilula, isisindo esilula kunezinye izinhlobo zamavalvu anobubanzi obufanayo, futhi unezidingo eziphansi zokusekelwa kwamapayipi ngesikhathi sokufakwa. Isihlalo sesango nesivalo singahlakazwa futhi sishintshwe ngokuhlukana. Ngesikhathi sokulungiswa, asikho isidingo sokushintsha i-valve yonke, ukunciphisa izindleko zokulungisa.

5. Ingakwazi ukuzivumelanisa nezinga lokushisa eliphezulu, ukucindezela okuphezulu kanye nemithombo yezindaba ebolayo (njengamanzi angcolile amakhemikhali, i-acidic slurry). Ngokukhetha izinto ezimelana nokugqwala (njengensimbi engagqwali, enerabha), ingahlangabezana nezimo zokusebenza ezinzima zezimboni ezahlukahlukene futhi ibe nokuguquguquka okunamandla.

Uma unezidingo ezihlobene, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24!
