Iivalvu zokuvala amanzi zizinto ezingaziwayo ezikhusela iinkqubo zombhobho, ezisebenza njengeendawo ezibalulekileyo zokulawula ukhuseleko, ukugcinwa, kunye nokusebenza kakuhle. Ukukhetha uhlobo olufanelekileyo kuthintela ukuvuza, kunciphisa iingozi zomonakalo wamanzi, kwaye kuqinisekisa ukuthembeka kwenkqubo. Nantsi indlela yokwahlulahlula iintlobo ezisi-7 eziphambili zeevalvu, iindlela zazo, kunye nendawo ezigqwesa kuyo:

---

1. Iivalvu zeBhola: Iintshatsheli zeKota-Turn

• Indlela Ezisebenza Ngayo: Ibhola yentsimbi engagqwaliyo enebhobo ijikeleza ngama-90°. Ilungelelanisa ibhobo nombhobho = IVULIWE; i-perpendicular = VALA.

• Eyona ilungeleyo: Imigca yamanzi ephambili, ukuvalwa kweenkonzo ezingxamisekileyo.

• Kutheni Ukhetha:

  • Akukho kuvuza xa kuvaliwe

  • Ubomi bomjikelo obungaphezu kwama-500,000 (umz., iivalvu zebhola yobhedu zikaPinya)

  • Ulawulo olukhawulezileyo lokuvula/ukucima

• Imida: Ayifanelekanga ukuba i-flow throttling ifikelele kwi-flow throttling.

2. IiValvu zeSango: IiHorse zomsebenzi ezithembekileyo

• Indlela Ezisebenza Ngayo: "Isango" elimile okwesikwere liphakamisa/lehlisa ngevili lesandla ukuvimba/ukuvumela ukuhamba kwamanzi.

• Eyona ilungeleyo: Ukucima rhoqo (umz., imigca ephambili yokuhambisa).

• Kutheni Ukhetha:

  • Uyilo olupheleleyo = ukwehla okuncinci koxinzelelo

  • Ukutywinwa kwecala eliya kwicala elibini

• Imida:

  • Ukusebenza kancinci (ukujika okuninzi)

  • Isenokuba sengozini yokugqwala/ukubanjwa ngokuhamba kwexesha

3. Iivalvu zeGlobe: Abalawuli bokuhamba kakuhle

• Indlela Ezisebenza Ngayo: Iplagi (idiski) icinezela isihlalo ukuze ithintele ukuhamba kwamanzi. Ilungele ukugoba.

• Eyona ilungeleyo: Ukulinganisela/ukulawula ukuhamba kwamanzi (umz., i-HVAC, ukunkcenkceshela).

• Kutheni Ukhetha:

  • Ulawulo oluchanekileyo lokuhamba kwamanzi

  • Ukugcinwa lula

• Imida: Ukwehla koxinzelelo oluphezulu (indlela yokuhamba komoya efana no-Z).

---

4. Iivalvu zeButterfly: Zincinci kwaye zingabizi kakhulu

• Indlela Ezisebenza Ngayo: Idiski ijikeleza i-90° kwi-axis esembindini. Ihambelana ne-flow = IVULIWE; i-perpendicular = IVALIWE.

• Eyona ilungele: Iipayipi ezinkulu (i-HVAC, imboni).

• Kutheni Ukhetha:

  • Ilula kwaye iyafikeleleka

  • Ukusebenza ngokukhawuleza

• Imida:

  • Ukuvuza okunokwenzeka xa uxinzelelo luphezulu

  • Idiski iyayithintela indlela yokuhamba kwamanzi nokuba ivuliwe

5. Iivalvu zeSolenoid: Ukuzenzekelayo okuKhawulezayo

• Indlela Ezisebenza Ngayo: I-Electromagnet iphakamisa i-plunger ukuze ivule i-orifice (isebenza ngamandla). Iyavala xa ingasebenzi.

• Eyona ilungele: Iinkqubo ezizenzekelayo (umz., oomatshini bekofu, ukunkcenkceshela).

• Kutheni Ukhetha:

  • Ixesha lokuphendula le-Millisecond

  • Ulawulo olukude/lwe-PLC (umz., uthotho lwePYF lukaPincheng)

  • Ukusebenza kwemizuzwana eyi-≤0.5 (iimodeli eziqinisekisiweyo yi-NSF)

• Imida: Ifuna amandla; ilinganiselwe kwiincindi ezixineneyo.

---

6. Iivalvu zokujonga: Izithinteli zokuBuya kweMizila

• Indlela Ezisebenza Ngayo: Vumela ukuhambahamba kwicala elinye kuphela (ukujika, ukulifti, okanye uyilo lwentwasahlobo).

• Eyona ilungeleyo: Ukuthintela ungcoliseko (iibhoyila, imibhobho yamanzi amdaka).

• Kutheni Ukhetha:

  • Akukho mngcipheko wokubuyela umva

  • Akukho mfuneko yokungenelela ngesandla

• Imida: Ayilungiselelwanga ukucima; ixhomekeke ekuhambeni kombane.

7. Iivalvu zokuMisa ii-Angle: Amaqhawe agcina isithuba

• Indlela Ezisebenza Ngayo: Iivalvu eziqinileyo ezigobileyo ezingama-90° phantsi kwezinki/izindlu zangasese.

• Eyona ilungeleyo: Ukuvalwa kwezixhobo ezikufutshane.

• Kutheni Ukhetha:

  • Ukufikelela lula xa kulungiselelwa

  • Ufakelo lokucinezela okanye lokutyhala ukuze uqhagamshele

Iingcebiso zoBugcisa bokuFakela kunye noLondolozo

• Kuphephe Ukuvuza: Sebenzisa iteyiphu yokutywina intambo (PTFE) kwintambo yamadoda.

• Izinto ezifunekayo ukuze kufikelelwe: Faka iivalvu ezikumgama weemitha ezi-3 ukusuka kwizixhobo (iikhowudi zasekuhlaleni).

• Uvavanyo lwekota: Cima/vala iivalvu ukuthintela ukubanjwa.

• Phucula iSmart: Tshintsha iivalvu zesango ngeevalvu zebhola ukuze uthembeke.

Ubusazi? I-10% yezindlu zineengxaki zeevalvu ezifihlakeleyo. Iivalvu zebhola zanamhlanje zihlala iminyaka engama-20 nangaphezulu xa kuthelekiswa neevalvu zesango ezihlala iminyaka eyi-8–10.

Ukuthatha kokugqibela
Ukususela kwiivalvu zebhola ezenziwe ngesandla ukuya kwiisolenoids ezilawulwa yi-AI, ukukhetha ivalvu yokuvala efanelekileyo kuthintela iintlekele kwaye kuphucula ukusebenza.Kwiinkqubo ezibalulekileyo zemisebenzi, hlola iivalvu eziqinisekisiweyo ezifana I-Pincheng'siivalvu zebhola ezingenamanziorii-solenoids ezingamelani nokugqwala—apho ukuchaneka kobunjineli kudibana nokuqina kwehlabathi lokwenyani.
