I-Spring and Swing Check Valves
Isahluko 1 – Yintoni iValuvu yokuHlola yaseNtwasahlobo?
I-valve yokukhangela i-spring yivalve eqinisekisa ukuhamba kwendlela enye kwaye inqande ukuhamba okubuyela umva.Zinendawo yokungena kunye neyokuphuma kwaye kufuneka zibekwe kwindawo efanelekileyo ukuze zisebenze kakuhle.Kwicala leevalve zokujonga intwasahlobo kunye nazo zonke iivalve zokujonga, kukho utolo olukhomba kwicala lokuhamba.Ivalve yokujonga i-spring-loaded ibizwa ngokuba yivalve yendlela enye okanye enye indlela.Injongo ye-valve yokuhlola i-spring kukusebenzisa i-spring kunye noxinzelelo olufakwe kwi-disc yokuyeka ukubuyisela umva ukuvala i-valve.

Ukuze i-valve yokutshekisha isebenze ngokufanelekileyo, kufuneka ibe noxinzelelo oluhlukeneyo, ihambe ukusuka kuxinzelelo oluphezulu ukuya kuxinzelelo oluphantsi.Uxinzelelo oluphezulu okanye uxinzelelo oluqhekezayo kwicala lokungena luvumela ulwelo ukuba luhambe ngevalve kwaye lunqobe amandla entwasahlobo kwivalve.

Ngokuqhelekileyo, i-valve yokutshekisha isixhobo esivumela nayiphi na indlela yemidiya ukuba ihambe kwicala elinye.Ubume bomatshini wokutshekisha bunokuba yingqukuva, idiski, ipiston okanye ipoppet, intloko yamakhowa.Iivalve zokuhlola i-Spring zithintela ukuhamba okujikelezayo njengendlela yokukhusela iimpompo, izixhobo kunye noomatshini xa uxinzelelo kwinkqubo luqala ukunciphisa, ukucotha, ukumisa okanye ukubuyisela umva.

Isahluko sesi-2 – Yintoni ivalve yokukhangela ujingi?
Iivalve zokujonga i-Swing zivumela ukuhamba kwendlela enye kwaye zivale ngokuzenzekelayo xa uxinzelelo lokuqhekeka luyancipha.Ziluhlobo lwevalve yebhabhathane enediski egqume ivalve.I-puck idityaniswe kwihinge ukwenzela ukuba xa ibethelwa ukuhamba kwemidiya, i-puck ingajiyiza ivule okanye ivalwe.Utolo olukwicala lomzimba wevalvu lubonisa icala lokuqukuqela kwamanzi ngaphakathi nangaphandle kwevalve.

Inqanaba loxinzelelo lolwelo lityhala idiski okanye umnyango uvuleke, uvumela ulwelo ukuba ludlule.Xa ukuhamba kuhamba ngendlela engafanelekanga, i-disc ivala ngenxa ye-thrust ye-liquid okanye i-medium.

Ivalve yokujonga ujingi

Iivalve zokujonga i-Swing ayifuni amandla angaphandle.Ukuhamba kolwelo okanye imithombo yeendaba kuzo akuthintelwa bubukho bazo.Zifakwe ngokuthe tye kwimibhobho, kodwa zinokufakelwa ngokuthe nkqo nje ukuba ukuhamba kuphezulu.

Isahluko sesi-3 – Iindidi ze-Spring Check Valves
Ukuze i-valve yokuhlola i-spring-loaded isebenze ngokufanelekileyo, kufuneka ibe noxinzelelo oluphezulu, olubizwa ngokuba yi-cracking pressure, ukuyigcina ivulekile.Ubungakanani boxinzelelo lokuqhekeka olufunekayo kuxhomekeke kuhlobo lwe-valve, ukwakhiwa kwayo, iimpawu zentwasahlobo kunye nokuqhelaniswa kwayo kwipayipi.Iinkcazo zoxinzelelo oluqhekezayo kwiipounds nge-intshi yesikwere (PSIG), iipounds nge-intshi yesikwere (PSI), okanye ibha, kunye neyunithi ye-metric yoxinzelelo ilingana ne-14.5 psi.

Xa uxinzelelo olunyukayo luphantsi kunoxinzelelo oluqhekezayo, uxinzelelo lwangasemva luba yinto kwaye ulwelo luya kuzama ukuphuma kwi-outlet kwi-valve ukuya kwindawo yokungena.Xa oku kusenzeka, ivalve ivala ngokuzenzekelayo kwaye ukuhamba kuyeka.

UHlobo lweValve yaseNtwasahlobo
Ivalve yokujonga i-axial flow cwaka
Nge-axial flow silent check valve, ipleyiti yevalve ibanjwe endaweni yi-spring ebeka ipleyiti yevalve ukuhamba kakuhle kunye nokuvula nokuvala ngokukhawuleza.Intwasahlobo kunye nediski zisembindini wombhobho, kwaye ulwelo luhamba lujikeleze idiski.Oku kwahlukile kwiivalve zokuguqula okanye ezinye iintlobo ze-spring valve, ezikhupha i-disc ngokupheleleyo kumanzi, zishiya ityhubhu evulekile ngokupheleleyo.

Uyilo olukhethekileyo lwevalve yokujonga i-axial flow cwaka yenza ukuba kubize kakhulu kuneevalvu zesiqhelo zokujonga intwasahlobo kunye neevalvu zokujonga ujingi.Ngelixa zibiza kakhulu, imbuyekezo kutyalo-mali ibangelwa kubomi babo obude, obunokuthatha iminyaka emithathu ukubuyisela.

Ukwakhiwa okuyingqayizivele kwe-Axial Flow Quiet Check Valve ikuvumela ukuba ubone ngezantsi apho i-valve ivula kunye nokuhamba kwamanzi.Njengeevalve zokujonga intwasahlobo, iivalve ze-axial zokujonga ziqala ukuvala xa uxinzelelo oluphezulu lwehla.Njengoko uxinzelelo luyehla kancinci, ivalve ivaleka kancinci.

Iivalvu zebhola zasentwasahlobo zisebenzisa ibhola njengesihlalo sokutywina kufutshane nomngxuma wokungena.Isihlalo sokutywina sifakwe isikhokelo ukukhokela ibhola kuyo kwaye yenze itywina eliqinisekileyo.Xa uxinzelelo lokuqhekeka lokuhamba lukhulu kunentwasahlobo ephethe ibhola, ibhola iyashukunyiswa,
