Ukutyhila Umahluko: Ibhola vs. Ivalvu Yokujonga – Yeyiphi Elawulayo Ephakamileyo

Ivalvu yeBhola vs. Ivalvu yokujonga - Uthelekiso oluSebenzayo

Ukuba wakha wasebenza kwinkqubo yokuhambisa imibhobho, mhlawumbi ukhe wajongana nalo mbuzo:Ngaba kufuneka ndisebenzise ivalvu yebhola okanye ivalvu yokujonga?Zibonakala zahlukile, zisebenza ngokwahlukileyo, kwaye zisebenza ngeenjongo ezahlukeneyo — kodwa abantu abaninzi bayazidida.

Ndikhumbula ndinceda isityalo esincinci sokucocwa kwamanzi amdaka kwiminyaka embalwa eyadlulayo. Bafake ivalvu yokujonga apho kwakufuneka khona ivalvu yebhola, kwaye isiphumo saba kukulahlekelwa koxinzelelo rhoqo. Loo mpazamo incinci yababiza iintsuku ezintathu zokusombulula iingxaki. Ngoko masilungise izinto kube kanye.

Yintoni Eyenza Ivalvu Nganye Yahluke?

Ivalvu yeBhola – Umlawuli wokuhamba kweManual

Ivalvu yebhola isebenzisa ibhola engenanto enomngxuma ophakathi. Xa ujika isiphatho ngama-90 degrees, umngxuma uhambelana nombhobho (uvuleke) okanye uwuvale (uvaliwe). Yiyo leyo — ilula, ikhawuleza, kwaye ithembekile.

Apho ikhanya khona:

• Ukuvalwa kwemeko kaxakeka (ikota yokujika = ukuma kwangoko)
• Imigca yegesi okanye yeoyile enoxinzelelo oluphezulu
• Izicelo apho ufuna utywino oluqinileyo nangona emva kweenyanga ungasetyenziswa

Intetho yokwenyani: Iivalvu zebhola azilungele ukuqhoboshelwa kakuhle. Ukuba uzama ukuzigcina zivulekile ixesha elide, isihlalo sinokuguga ngendlela engalinganiyo.

I-Check Valve - I-Automatic Bodyguard

Ivalvu yokujonga ayinasiphatho. Iyavuleka xa ulwelo luhamba phambili, kwaye ivala ngokuzenzekelayo xa ukuhamba kujika okanye kuyeka. Akukho senzo somntu sifunekayo.

Apho ikhanya khona:

• Imigca yokukhupha impompo (ithintela ukubuya kwamanzi xa impompo iyeka)
• Iimpompo zesump kwizindlu ezingaphantsi komhlaba
• Iinkqubo zomphunga okanye zokufuma apho ukuhamba okungasemva kunokonakalisa izixhobo

Okucaphukisa abantu: Jonga ukuba iivalvu zingavaleka xa ulwelo luyema ngequbuliso. Eso sandi sokubethela asisosandi nje kuphela - sinokuqhekeza amalunga emibhobho ngokuhamba kwexesha.

Ivalvu yeBhola vs. Ivalvu yokujonga: Umahluko oPhambili

1. Ukusebenza kunye noYilo:

- Iivalvu zeBhola: Iphawulwa yibhola ejikelezayo enembobo, iivalvu zebhola zilawula ukuhamba kwebhola ngokujikelezisa ibhola iidigri ezingama-90. Zibonelela ngokuvala ngokukhawuleza, ukwehla koxinzelelo oluncinci, kunye nolawulo lokuhamba kwebhola kwicala ngalinye. Ilungele ukusetyenziswa kokuvula/ukucima kwimizi-mveliso yeoyile, igesi, kunye neekhemikhali.

- Jonga iiValvu: Yenzelwe ukuvumela ukuhamba kwe-unidirectional, iivalvu zokujonga zithintela ngokuzenzekelayo ukubuya kwe-backflow. Azinalo ulawulo lwesandla kwaye zixhomekeke kuxinzelelo lolwelo ukuze zivuleke/zivalwe. Zisetyenziswa kakhulu kwiinkqubo zamanzi, iimpompo, kunye ne-HVAC.

2. Ukusebenza kakuhle:

- Iivalvu zebhola ziyagqwesa kwiindawo ezinoxinzelelo oluphezulu, ezinobushushu obuphezulu ngenxa yokutywinwa kwazo okuqinileyo.

- Jonga iivalvu kuqala ukhuseleko kwiinkqubo apho ukuthintela ukubuya kwamanzi kubalulekile kodwa kufuna ulondolozo oluncinci.

3. Izicelo:

Iivalvu zebhola zilawula kwiimeko zokucima nokuvala.

- Qinisekisa ukuba iivalvu ziyakhanya kwiinkqubo ezifuna ukuthintela ukubuyela umva ngokuzenzekelayo.

Icala ngecala: Itheyibhile yokuthelekisa ngokukhawuleza

Iintlobo Eziqhelekileyo Oza Kudibana Nazo

Iinguqu zevalvu yebhola

• Ibhola edadayo: Eyona ixhaphakileyo, ifikelelekayo, isebenza kakuhle kuxinzelelo oluphantsi ukuya koluphakathi.
• I-Trunnion ifakelwe: Inkxaso eyongezelelweyo yoxinzelelo oluphezulu (cinga ngemibhobho yeoyile).
• I-V-port: Ibhola ekhethekileyo enenotshi efana no-V — ivumela ulawulo olulinganiselweyo lokuhamba kwamanzi, kungekuphela nje ukuvulwa/ukuvalwa.

Jonga utshintsho lweevalvu

• Itshekhi yokujika: I-hinged flap iyavuleka. Isebenza kakuhle kwimibhobho ethe tye.
• Ukujonga ilifti: Idiski iphakama inyuka ihla. Ilungele umphunga okanye amanzi anoxinzelelo oluphezulu.
• Ipleyiti ezimbini / ukujonga i-wafer: Incinci kakhulu, ingena phakathi kweeflange. Ithandwa kakhulu kwiindawo ezixineneyo.

Ndakha ndabona ivalvu yokujonga iipleyiti ezimbini ifakwe ngokuthe nkqo kwisityalo seekhemikhali - kwaye yayisebenza kakuhle kuba uyilo oluncediswa yintwasahlobo lwalulawula amandla adonsela phantsi komhlaba. Kodwa ukujonga okuqhelekileyo kokujika ngekwakungaphumelelanga apho. Iinkcukacha zibalulekile.

Indlela yokukhetha iValve efanelekileyo (kunye noMboneleli)

Ngaphambi kokuba uthenge, zibuze imibuzo emithathu:

1. Ngaba ndifuna ulawulo lwesandla okanye ukhuseleko oluzenzekelayo?

   • Ukuba uyafuna ukuyeka ukuhamba kwemveliso xa kuyimfuneko→ ivalvu yebhola
   • Ukuba uyafuna ukuthintela ukuhamba ngasemva ngokuzenzekelayo→ ivalvu yokujonga
   • Ngamanye amaxesha udinga zombini ezi zinto zilandelelana — ewe, oko kuqhelekile.

2. Ingakanani uxinzelelo lwam, ubushushu, kunye nolwelo?

   • Iikhemikhali ezidlakazelayo? Sebenzisa intsimbi engagqwaliyo okanye iivalvu zebhola ezine-PTFE.
   • Amanzi amdaka amdaka? Itshekhi yokujika ene-flap yerabha ingahlala ixesha elide kuneyesinyithi.

3. Ngubani umthengisi wam?

   • Cela iingxelo zovavanyo (uvavanyo loxinzelelo, uvavanyo lokuvuza kwesihlalo).
   • Jonga ukuba bagcina ubungakanani obufanayo okanye bafuna iiodolo ezenziwe ngokwezifiso — ixesha lokufumana izinto libulala iiprojekthi.
   • Khangela i-ISO 9001, kodwa ungawanquli amagcisa. Ndibabonile ababoneleli abaqinisekisiweyo bethengisa amagcisa amabi. Cela iireferensi ezivela kumashishini afanayo.

Ibali Elifutshane Ngokukhethwa Kwababoneleli

Umthengi wam wayefuna iziqwenga ezingama-20 zeevalvu zokujonga eziziisentimitha ezi-6 zesitishi sokunkcenkceshela. Esona xabiso singabizi kakhulu sivela kumthengisi ongaziwayo kwi-intanethi. Bagcine i-30% kwangaphambili - kodwa emva kweenyanga ezintathu, iivalvu ezimbini azizange zivale. Ihamile yamanzi yaqhekeza i-ankile yekhonkrithi. Ixabiso lokulungisa ladla imali elongeziweyo ngokuphindwe kalishumi.

Ngoku ndihlala ndisithi:Ixabiso yiloo nto uyihlawulayo; ixabiso yiloo nto uyifumanayo.Umthengisi othembekileyo uza kukunika izatifikethi zezinto eziphathekayo, iividiyo zovavanyo, kunye newaranti ecacileyo. Musa ukulibala loo nto.

Isigqibo Sokugqibela – Nguwuphi “olawulayo oPhakamileyo”?

Akukho nanye kwezi. Yiyo leyo impendulo enyanisekileyo.

• Iivalvu zebhola ziinkosi zokuvala ngesandla.
• Iivalvu zokujonga ziingongoma zokuthintela ukubuya kwamanzi.

Awunakuyitshintsha enye ngenye. Ukhetho olufanelekileyo luxhomekeke ngokupheleleyo kwiimfuno zenkqubo yakho. Ukuba ufuna zombini imisebenzi, faka zombini — shiya nje indawo eyaneleyo yokulungisa.
