Iivalvu zoshishino ezahlukeneyo zinemisebenzi eyahlukeneyo.Ezinye iivalvu zisetyenziselwa ukulungelelanisa ukuhamba, ezinye zisetyenziselwa ukuhamba kunye nokunqunyulwa, kwaye ezinye zisetyenziselwa ukutshintsha icala lolwelo.

Okwangoku, iivalve zebhola kunye neevalvu zesango zezona zimbini zisetyenziswa kakhulu.Kweli nqaku, siza kukwazisa umahluko phakathi komgaqo wokusebenza kunye nokusetyenziswa.Ndiyathemba ukukunceda uqonde ngcono kwaye ukhethe ivalve.

Yintoni naivalve yebhola?

Ivalve yebhola luhlobo lwevalve yekota.Kukho ingqukuva ngaphakathi kumzimba wevalvu.Ingqukuva ijikelezisa ikota yokujika kunye nesiqu sevalve ukuvula okanye ukuvala ivalve.Ngaphakathi kwingqukuva kukho umngxuma, nto leyo evumela ulwelo ukuba luthuthwe.

Ngokutsho koyilo, i-valve yebhola inokwahlulwa ibe yindlela ezimbini, ezintathu okanye ezine-i-valve yebhola, esetyenziselwa ukujikeleza, ukunqunyulwa, ukuguqula indlela yokuhamba kwe-medium, confluence and divergence.

Iivalvu zebhola zisetyenziswa ngokubanzi kumashishini anoxinzelelo oluphantsi.Ukuba ufuna ukuyisebenzisa kushishino oluphezulu, kufuneka wenze ngokwezifiso i-valve yebhola enokumelana noxinzelelo oluphezulu.

Ivalve yebhola inokwenziwa ngeplastiki, ubhedu, intsimbi engatyiwayo okanye intsimbi yekhabhoni.

Ngenxa yobungakanani obunqamlekileyo be-valve yebhola, iya kulungeleka ukusetyenziswa kwiibhobho ezincinci, ezifana nemboni yokucoca amanzi, isityalo sombane, imboni yebhoyili, imboni yokwakha iinqanawa kunye nokunye.

Yintoni naivalve yesango?

Ivalve yesango yivalve ejikelezayo.I-flap yevalve iya phezulu okanye ezantsi ukuvula okanye ukuvala ivalve.Iivalvu zesango nazo zinokwahlulwa zibe ziivalve zesango lemela ngokoyilo lwazo.Ivalve yesango yivalve eneendlela ezimbini engenazo iimfuno zendlela yokuhamba.

Ivalve yesango inokuvulwa ngokupheleleyo okanye ivalwe ngokupheleleyo, ngoko ke ivalve yesango ingasetyenziselwa ukuhamba nokunqunyulwa, kwaye ayikwazi ukulungelelanisa ukuhamba.Ivalve yesango ayilula ukuba ivalwe, ngoko ifanelekile kakhulu kwizityalo zesamente, iphepha kunye ne-pulp njalo njalo.

Ivalve yesango inokwenziwa ngeplastiki, intsimbi ekhandiweyo, intsimbi engatyiwayo okanye intsimbi yekhabhoni.

Ivalve yesango inoluhlu olubanzi kakhulu lobungakanani, ngoko ingasetyenziswa kulo naliphi na ishishini, njengezityalo zokulungisa ukutya, ukucocwa kwamanzi amdaka, i-oyile kunye negesi, kunye namashishini azenzekelayo.

Shwankathela

Zombini iivalve zebhola kunye neengcango zesango zineenzuzo zazo, ngoko ukuqonda imisebenzi yazo kunokukunceda ukhethe ivalve.Ukuba ufuna isikhokelo sokhetho, wamkelekile ukuba uqhagamshelane nathi.Siyavuya ukukunceda.
