Iivalvu zesangoZizinto ezibalulekileyo kwiinkqubo zemibhobho yemizi-mveliso neyezindlu, ezenzelwe ukulawula ukuhamba kolwelo okanye iigesi. Zaziwa ngokuthembeka kwazo nokusebenza ngokulula, zidlala indima ebalulekileyo kwizicelo ezifuna ukuhamba ngokupheleleyo okanye ukucima ngokupheleleyo. Kweli nqaku, siza kuhlola ukuba yintoni ivalvu yesango, indlela esebenza ngayo, iingenelo zayo, iindlela ezilungileyo zokugcinwa, kunye nendlela eyahluke ngayo kwezinye iintlobo zeevalvu ezifana neevalvu zeglobe, iivalvu zebhola, kunye neevalvu zokujonga.
Yintoni iValve yeSango
A ivalvu yesangoyivalvu ehamba ngomgca othe tyaba okanye omile okwesikwere (idiski) ukuqala okanye ukumisa ukuhamba kolwelo. Isango lihamba ngokuthe nkqo kwicala lolwelo, nokuba livula ngokupheleleyo indlela yokuhamba ngaphandle kwemida okanye liyivale ngokuqinileyo ukuze livale i-medium. Iivalvu zesango zihlala zisetyenziswa kwiinkqubo apho kufuneka ukwehla koxinzelelo oluncinci kunye nokusebenza okungacwangciswanga rhoqo, njengakwimibhobho yokuhambisa amanzi, amashishini eoyile negesi, kunye neenkqubo zeHVAC.
Isebenza njani iValve yeSango
Ukusebenza kwevalvu yesango kuxhomekeke kwindlela elula kodwa esebenzayo:
1. Ukuvula iValve: Xa ivili lesandla okanye i-actuator ijikeleziswa ngokuchasene newotshi, isango liphakanyiswa liye phezulu ngesiqu esinemisonto, nto leyo eyenza indlela engaphazanyiswa lulwelo.
2. Ukuvala iValve: Ukujika ivili lesandla ngokwewotshi kwehlisa isango lide lihlale ngokuqinileyo emzimbeni wevalvu, nto leyo edala ukuvalwa okuqinileyo nokuthintela ukuhamba kwamanzi.
Iivalvu zesango zenzelweivuliwe ngokupheleleyo okanye ivaliwe ngokupheleleyoukusebenza kwazo, nto leyo ezenza zingafaneleki ukuqhoboshelwa (ukunciphisa ukuhamba kwazo kancinci). Ukuhamba kwazo ngomgca kuqinisekisa ukuxinana okuncinci kunye nokulahlekelwa koxinzelelo xa zivuliwe ngokupheleleyo.
Iingenelo zeeValve zeSango
- Cima Kakhulu: Ibonelela ngokutywina okugqwesileyo, ithintela ukuvuza kwiindawo ezivaliweyo.
- Ukwehla koxinzelelo oluphantsi: Uyilo olupheleleyo lunciphisa ukumelana xa luvuliwe ngokupheleleyo.
- Ukuqina: Ulwakhiwo oluqinileyo lufanele iindawo ezixinezelekileyo nezishushu kakhulu.
- Ukuhamba kweendlela ezimbini: Iyakwazi ukusingatha ukuhamba kwamanzi kuyo nayiphi na indlela.
- Uyilo olulula: Kulula ukuyisebenzisa nokuyigcina ikwimeko entle.
Iingcebiso Zokugcinwa Kweevalvu Zesango
Ukugcinwa kakuhle kwandisa ubomi beevalvu zesango:
1. Uhlolo oluQhelekileyo: Jonga ukuba akukho mhlwa, ukuvuza, okanye umonakalo obangelwe sisiqu.
2. Ukuthambisa: Faka igrisi kwimisonto yesiqu ukuqinisekisa ukusebenza kakuhle.
3. Ukucoca: Susa inkunkuma emzimbeni wevalvu kunye nesango ukuthintela ukuxinana.
4. Ukutshintshwa kweTywina: Buyisela izitywini okanye ukupakisha okugugileyo ukuze kugcinwe ukusebenza okungenakuvuza.
5. Kuphephe Ukuziqinisa Ngokugqithisileyo: Amandla agqithisileyo anokonakalisa isango okanye isihlalo.
I-Gate Valve vs. Globe Valve vs. Ball Valve vs. Check Valve
1. Ivalvu yeSango vs. Ivalvu yeGlobe
- UmsebenziIivalvu zesango zezokulawula ukuvala/ukuvula; iivalvu zeglobhu zilawula ukuhamba kwamanzi.
- UyiloIivalvu zeglobe zinomzimba ontsonkothileyo omile okwe-Z wokugoba, ngelixa iivalvu zesango zinomzimba olungelelanisiweyo.
- Ukwehla koxinzeleloIivalvu zeglobe zibangela ukwehla koxinzelelo oluphezulu xa zivuliwe kancinci.
2. I-Sango Valve vs. I-Ball Valve
- Umsebenzi: Iivalvu zebholasebenzisa ibhola ejikelezayo enebhore ukuze uvale ngokukhawuleza; iivalvu zesango zisebenzisa intshukumo ethe tye.
- IsantyaIivalvu zebhola zisebenza ngokukhawuleza kodwa zinokuguga ngokukhawuleza xa zisetyenziswa rhoqo.
3. Ivalvu yeSango vs. Ivalvu yokujonga
- Isikhokelo sokuhamba komoya: Qinisekisa ukuba iivalvu zivumela ukuhamba kwicala elinye kuphela; iivalvu zesango zicala-mbini.
- Ukuzenzekelayo: Qinisekisa ukuba iivalvu zisebenza ngokuzenzekelayo, ngelixa iivalvu zesango zifuna ulawulo lwesandla okanye lwe-actuator.
Isiphelo
Iivalvu zesango zibalulekile kwiinkqubo ezifuna ukuvalwa okuthembekileyo kunye nokumelana okuphantsi. Ukuqonda ukusebenza kwazo, iingenelo, kunye neemfuno zokugcinwa kwazo kuqinisekisa ukusebenza kakuhle. Nangona zahlukile kwiivalvu zeglobe, ibhola, kunye nokujonga kuyilo kunye nomsebenzi, ukukhetha ivalvu efanelekileyo kuxhomekeke kwiimfuno zenkqubo yakho. Ukuze usebenze ixesha elide, beka phambili uhlolo oluqhelekileyo kunye nokulungiswa ngexesha elifanelekileyo.
Ngokuqonda iziseko zeevalvu zesango, ungenza izigqibo ezinolwazi malunga nezicelo zemizi-mveliso, zorhwebo, okanye zokuhlala.
