Isahluko 1 – Iyini Ivalvu Yokuhlola Intwasahlobo?
I-valve yokuhlola intwasahlobo iyi-valve eqinisekisa ukugeleza kwendlela eyodwa futhi ivimbele ukugeleza okubuyela emuva. Anendawo yokungena nokuphuma futhi kufanele abekwe endaweni efanele ukuze asebenze kahle. Ohlangothini lwama-valve okuhlola intwasahlobo nawo wonke ama-valve okuhlola, kunomcibisholo okhomba lapho kugeleza khona. I-valve yokuhlola elayishwe entwasahlobo ibizwa ngokuthi i-valve yendlela eyodwa noma i-valve yendlela eyodwa. Inhloso ye-valve yokuhlola i-spring iwukusebenzisa isiphethu kanye nokucindezela okufakwe ku-disc ukuze kumiswe ukubuyela emuva ukuvala i-valve.

Ukuze i-valve yokuhlola isebenze kahle, kufanele ibe nokucindezela okuhlukile, ukugeleza kusuka ekucindezelweni okuphezulu kuya ekucindezelweni okuphansi. Ukucindezela okuphezulu noma ukucindezela okuqhekeka ohlangothini lokungena kuvumela uketshezi ukuthi lugeleze ku-valve futhi lunqobe amandla entwasahlobo ku-valve.

Ngokuvamile, i-valve yokuhlola iyithuluzi elivumela noma yiluphi uhlobo lwemidiya ukuthi lugeleze ohlangothini olulodwa. Ukuma komshini wokuhlola kungaba yindilinga, i-disc, i-piston noma i-poppet, ikhanda lamakhowe. Ama-valve okuhlola entwasahlobo avimbela ukugeleza okubuyela emuva njengendlela yokuvikela amaphampu, izinto zokusebenza nemishini lapho ingcindezi ohlelweni iqala ukuncipha, ihamba kancane, ima noma ihlehla.

Isahluko 2 – Iyini ivalve yokuhlola ukujika?
Ama-valve okuhlola ama-Swing avumela ukugeleza kwendlela eyodwa futhi avale ngokuzenzakalelayo lapho ukucindezela kokuqhekeka kuncipha. Ziwuhlobo lwevalve uvemvane enediski emboze ukuvulwa kwevalvu. I-puck ixhunywe kuhinge ukuze kuthi lapho ishaywa ukuhamba kwemidiya, i-puck ingashwibeka ivuleke noma ivalwe. Umcibisholo oseceleni komzimba we-valve ubonisa isiqondiso sokugeleza koketshezi ngaphakathi nangaphandle kwe-valve.

Izinga lokucindezela koketshezi liphusha i-disc noma umnyango uvule, okuvumela uketshezi ukuba ludlule. Lapho ukugeleza kuhamba ngendlela engafanele, i-disc iyavala ngenxa yokuphonswa koketshezi noma okuphakathi.

I-valve yokuhlola i-Swing

Ama-valve okuhlola ama-Swing awadingi amandla angaphandle. Ukudlula koketshezi noma imidiya kuzo akuvinjwa ukuba khona kwazo. Afakwe ngokuvundlile emapayipini, kodwa angafakwa ngokuqondile inqobo nje uma ukugeleza kubheke phezulu.

Isahluko sesi-3 – Izinhlobo zamavalvu okuhlola intwasahlobo
Ukuze i-valve yokuhlola elayishwe entwasahlobo isebenze kahle, kufanele ibe nomfutho okhuphuka nomfula, obizwa ngokuthi i-cracking pressure, ukuze ihlale ivulekile. Inani lokucindezela kokuqhekeka elidingekayo lincike ohlotsheni lwe-valve, ukwakhiwa kwalo, izici zasentwasahlobo kanye nokuma kwayo epayipini. Imininingwane yokucindezela kokuqhekeka ikuphawundi ngeyintshi yesikwele (PSIG), amaphawundi ngeyintshi yesikwele (PSI), noma ibha, futhi iyunithi yemethrikhi yokucindezela ilingana no-14.5 psi.

Lapho umfutho okhuphuka nomfula uphansi kunokucindezela kokuqhekeka, ukucindezela emuva kuba yisici futhi uketshezi luzozama ukugeleza lusuka lapho kuphuma khona i-valve luye endaweni yokungena. Uma lokhu kwenzeka, i-valve ivala ngokuzenzakalelayo futhi ukugeleza kuyama.

I-Spring Check Valve Uhlobo
I-axial flow ithule i-valve yokuhlola
Nge-axial flow silent check valve, i-valve plate ibanjwe isiphethu esibeka phakathi ipuleti levalvu ukuze ligeleze kahle futhi livuleke futhi livaleke ngokushesha. I-spring ne-disc kuphakathi nendawo yepayipi, futhi uketshezi lugeleza luzungeze i-disc. Lokhu kuhlukile kuma-valve e-swing noma ezinye izinhlobo zama-valve asentwasahlobo, akhipha i-disc ngokuphelele oketshezini, eshiya ithubhu evulekile ngokugcwele.

Idizayini ekhethekile ye-axial flow silent check valve yenza ibize kakhulu kunamavalvu okuhlola entwasahlobo endabuko kanye nama-valve okuhlola ngokushwibeka. Nakuba zibiza kakhulu, imbuyiselo ekutshalweni kwezimali ingenxa yokuphila kwazo okude, okungathatha iminyaka emithathu ukushintshwa.

Ukwakhiwa okuyingqayizivele kwe-Axial Flow Quiet Check Valve ikuvumela ukuba ubone ngezansi lapho i-valve ivula khona futhi kugeleza uketshezi. Njengama-valve okuhlola entwasahlobo, ama-axial check valve aqala ukuvala lapho umfutho okhuphukayo wehla. Njengoba ingcindezi iyancipha kancane, i-valve ivala kancane.
