Kukhona umehluko osobala phakathi kwama-valve esango lesilayidi kanyeamavalvu esango lommesengokwesakhiwo, umsebenzi kanye nezimo zokusetshenziswa:

1. Umklamo wesakhiwo

Isango levalvu yesango elishelelayo liyisicaba, futhi indawo yokuvala imvamisa yenziwe nge-alloy eqinile noma irabha. Ukuvulwa nokuvalwa kufezwa ngokushelela okuvundlile kwesango eceleni kwesihlalo sevalvu. Isakhiwo siyinkimbinkimbi kakhulu, futhi ukusebenza kokuvala kuncike ekulinganeni kahle kwesango nesihlalo sevalvu.

Isango le-valve yesango lensimbi eliyi-ductile lisesimweni se-blade, elingasika imicu, izinhlayiya kanye nokunye ukungcola endaweni. Linesakhiwo esincanyana kakhulu. Indawo yokuvala phakathi kwesango nesihlalo se-valve yakhelwe kakhulu njengokuxhumana kwensimbi eqinile, okunamandla okuguguleka.

2. Ukusebenza kokuvala

I-valve yesango elishelelayo isebenza kahle ekuvaleni futhi ifaneleka kakhulu ngezikhathi lapho kunezidingo eziphezulu zokuvuza (njenge-gas media). Amanye amamodeli afakwe isakhiwo sokuvala kabili.

Ukuvalwa kwevalvu yesango lommese we-flange kugxile ekuvimbeleni ukuguguleka futhi kufanelekile kuma-media aqukethe izinhlayiya eziqinile, udaka, njll. Indawo yokuvala ingalungiswa ngokugaya, kodwa ukuvuza kukhulu kancane kunokwevalvu yesango le-slide plate.

3. Izimo Zokusebenza

Amavalvu esango elishelelayo asetshenziswa kakhulu ekuhlanzeni izinto ezifana nemikhiqizo yegesi namafutha, noma ezinhlelweni zamapayipi ezidinga ukuvalwa okuqinile.

Amavalvu esango lommese anenjini afaneleka kakhulu ezintweni eziqukethe ukungcola okufana nendle, i-pulp, kanye nempuphu yamalahle, futhi avame ukusetshenziswa emikhakheni efana ne-metallurgy, izimayini, kanye nokuvikelwa kwemvelo.

I-Jinbin Valve igxile ekukhiqizweni nasekulungiselelweni kwamavalvu esango lommese amakhulu. Ivalvu yesango lommese enkulu (enobubanzi obungu-≥DN300) isetshenziswa kabanzi emapayipini ezimboni ngenxa yezinzuzo zayo zesakhiwo nokusebenza.

Ipuleti lesango elinomumese lingasika kalula imicu, izinhlayiya noma izinto ezinamathelayo (njenge-slurry, i-pulp) endaweni ephakathi, livimbele ukungcola ukuthi kuqongelelane futhi kuvimbe ivalvu. Lifaneleka kakhulu ekuthuthweni kwezinto eziqukethe izinto eziqinile ezilengayo, kunciphisa imvamisa yokugcinwa kwamapayipi.

2. Umzimba wevalvu usebenzisa umklamo oqondile, obonisa ukumelana nokugeleza okuphansi kanye nokushaya okufushane kokuvula nokuvala kwesango. Uma kuhlanganiswa nama-actuator kagesi noma omoya, kungafinyelela ukuvulwa nokuvala okusheshayo, kunciphisa ubunzima bokusebenza kwamavalvu amakhulu futhi kuwenze afanelekele izimo zokulawula okuzenzakalelayo.

3. Izindawo zokuvala zenziwe kakhulu nge-alloy eqinile noma insimbi eqinile engagugi, enamandla okulwa nokuguguleka. Ngisho noma zisetshenziswa isikhathi eside ngesivinini sokugeleza okuphezulu noma ezindabeni eziqukethe izinhlayiya, zingagcina ukusebenza okuhle kokuvala futhi zinciphise izindleko zokufaka esikhundleni.

4. Umzimba wevalvu unesakhiwo esilula, unesisindo esilula kunezinye izinhlobo zamavalvu anobubanzi obufanayo, futhi unezidingo eziphansi zokusekelwa kwephayiphi ngesikhathi sokufakwa. Isihlalo sesango nevalvu singahlukaniswa futhi sishintshwe ngokwehlukana. Ngesikhathi sokulungiswa, asikho isidingo sokushintsha lonke ivalvu, okunciphisa izindleko zokulungisa.

5. Ingazivumelanisa nokushisa okuphezulu, umfutho ophezulu kanye nezinto ezigqwalisayo (njengamanzi angcolile amakhemikhali, udaka olune-asidi). Ngokukhetha izinto ezingagqwali (njengensimbi engagqwali, efakwe irabha), ingahlangabezana nezimo zokusebenza ezinzima zezimboni ezahlukene futhi inokuguquguquka okunamandla.

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