Yintoni iValve yoNcedo?

Kwimisebenzi eyahlukeneyo yemizi-mveliso, ulawulo loxinzelelo lubalulekile kukhuseleko nokusebenza kakuhle kwemisebenzi. Enye yezinto ezibalulekileyo ezisetyenziswayo ukulawula uxinzelelo yivalvu yokunceda. Eli nqaku liza kujonga ukuba yintoni ivalvu yokunceda, iintlobo zayo, indlela esebenza ngayo, ukusetyenziswa kwayo, kunye nokubaluleka kokugcinwa ngokufanelekileyo.

Ukuqonda iiValvu zoNcedo

Ivalvu yokunceda sisixhobo sokhuseleko esenzelwe ukulawula okanye ukunciphisa uxinzelelo kwinkqubo. Ikhupha ngokuzenzekelayo uxinzelelo olugqithisileyo kwisitya okanye kwinkqubo yemibhobho ukuthintela umonakalo onokubakho okanye ukungaphumeleli okukhulu. Iivalvu zokunceda zibalulekile kumashishini ahlukeneyo, kubandakanya ioyile negesi, ukucutshungulwa kweekhemikhali, ukuveliswa kombane, kunye nokucocwa kwamanzi.

Indlela iiValvu zoNcedo eziSebenza ngayo

Iivalvu zokunceda zisebenza ngokusekelwe kumgaqo wokwahluka koxinzelelo. Xa uxinzelelo olungaphakathi kwenkqubo ludlula indawo ebekiweyo, ivalvu yokunceda iyavuleka, ivumela ulwelo (ulwelo okanye igesi) ukuba luphume. Eli nyathelo linciphisa uxinzelelo olungaphakathi kwenkqubo, lithintele ukonakala kwezixhobo kwaye liqinisekise ukusebenza ngokukhuselekileyo.

Izinto ezisisiseko zevalvu yokunceda ziquka:

1. Umzimba: Ulwakhiwo oluphambili olugcina izinto zangaphakathi.

2. Isihlalo: Umphezulu apho ivalvu ivala khona ukuthintela ukuhamba kwamanzi.

3. Idiski: Inxalenye eshukumayo evula kwaye ivala ivalvu.

4. Intwasahlobo: Inxalenye ebamba idiski kwisihlalo ide ifikelele kuxinzelelo olubekiweyo.

5. Indlela Yokulungisa: Indlela yokuseta uxinzelelo olufunekayo apho ivalvu iza kuvulwa khona.

Xa uxinzelelo lwenkqubo ludlula uxinzelelo olumiselweyo, amandla asetyenziswa lulwelo adlula amandla entwasahlobo, nto leyo ebangela ukuba idiski iphakame esihlalweni. Oku kuvumela ulwelo ukuba luphume kwinkqubo, nto leyo enciphisa uxinzelelo. Nje ukuba uxinzelelo lwehle ngaphantsi kwendawo emiselweyo, amandla entwasahlobo ayayivala ivalvu, ayeke ukuhamba.

Iintlobo zeeValvu zoNcedo
