Kwizicelo ezahlukeneyo zemizi-mveliso, ngakumbi ezo zibandakanya iinkqubo zehydraulic, ukusebenza kakuhle kunye nokuthembeka kwemisebenzi yokubamba kubaluleke kakhulu. Elinye icandelo elibalulekileyo eliphucula impumelelo yale misebenzi sisivalo esilingwayo sokujonga (i-POCV). Le bhlog iphonononga ukusebenza, iingenelo, kunye nokusetyenziswa kweevalvu zetshekhi eziqhutywayo kwiinkqubo zokubambelela.

Ukuqonda Pilot Operated Check Valves

A ivelufa yokuhlola esebenzayoluhlobo lwevalve yokutshekisha evumela ulwelo ukuba luhambe kwicala elinye ngelixa lukhusela umva. Ngokungafaniyo neevalvu zokuhlola ezisemgangathweni, ezixhomekeke kuphela kuxinzelelo olusuka kulwelo ukuvula nokuvala, iivalvu zokujonga eziqhutywa ngumqhubi wenqwelomoya zisebenzisa umqondiso wokulinga ukulawula ukusebenza kwazo. Olu phawu lwenza ukuba i-valve ihlale ivaliwe phantsi kweemeko ezithile, inika umgangatho ophezulu wokulawula kunye nokhuseleko kwiinkqubo ze-hydraulic.

Ukusebenza kwiMisebenzi yokuBamba

Kwimisebenzi yokubamba, ulawulo oluchanekileyo malunga nokuhamba kunye nokubekwa kwamacandelo kubalulekile. Ii-POCVs zidlala indima ebalulekileyo kule nkqubo ngokuqinisekisa ukuba xa icandelo libotshiwe, lihlala likhuselekile de umqhubi enze isigqibo sokulikhulula. Oku kubaluleke kakhulu kwizicelo ezifana nomatshini, ukudibanisa, kunye nokuphathwa kwezinto eziphathekayo, apho nayiphi na intshukumo engalindelekanga ingakhokelela ekungalungi okanye kwiingozi.

Xa kuqalwa umsebenzi wokubamba, inkqubo yoxinzelelo loxinzelelo oluvula i-POCV, ivumela ulwelo ukuba luhambe kwaye lubandakanye ibamba. Emva kokuba uxinzelelo olufunwayo luphunyeziwe, i-valve ihlala ivaliwe, ithintela nayiphi na i-backflow yolwelo. Le ndlela yokuvala iqinisekisa ukuba i-clamp igcina indawo yayo, inika uzinzo kunye nokhuseleko ngexesha lokusebenza.

Izinto eziluncedo zokusebenzisa ii-POCVs

Ukhuseleko olomeleziweyo: Ii-POCVs ziwunciphisa kakhulu umngcipheko wokukhutshwa ngengozi kwamalungu abambeneyo. Kwizicelo zoxinzelelo oluphezulu, ukukwazi ukuvala i-valve endaweni iqinisekisa ukuba nangona kukho ukuhla ngokukhawuleza koxinzelelo, i-clamp ihlala ibandakanyeka.

Ukusebenza okuphuculweyo: Ngokusebenzisa umqondiso womqhubi wokulawula i-valve, ii-POCVs zivumela amaxesha okuphendula ngokukhawuleza kunye nokusebenza kakuhle. Oku kusebenza kakuhle kunenzuzo ngokukodwa kwiinkqubo ezizenzekelayo apho ulungelelaniso olukhawulezayo luyimfuneko.

Ukuvuza okuNciphisiweyo: Uyilo lwee-POCVs lunciphisa amathuba okuvuza kwamanzi, okubalulekileyo ekugcineni ukuthembeka kwenkqubo kunye nokunciphisa iindleko zokulondoloza.

I-Versatility: Ii-POCVs zingasetyenziswa kwiinkqubo ezahlukeneyo ze-hydraulic, zizenza zilungele uluhlu olubanzi lwezicelo zokubethelela kumashishini ahlukeneyo.

Ulawulo olulula: Ukukwazi ukulawula i-valve kunye nomqondiso womqhubi we-pilot kwenza kube lula ukuyila isekethe ye-hydraulic jikelele, evumela ukuhlanganiswa okuthe ngqo kwiinkqubo ezikhoyo.

Izicelo kuShishino

Iivalve zokuhlola eziqhutywa ngumqhubi wepilot zisetyenziswa ngokubanzi kumashishini amaninzi, kubandakanya:

Ukuvelisa: Kwimisebenzi yomatshini, ii-POCVs ziqinisekisa ukuba ii-workpieces zigcinwe ngokukhuselekileyo ngexesha leenkqubo zokusika okanye zokomba, ziphucula ukuchaneka nokhuseleko.

I-Automotive: Kwimigca yendibano, ii-POCVs ziququzelela ukunyanzeliswa kweengxenye ngexesha le-welding okanye i-fastening, iqinisekisa ukuba amacandelo ahambelana ngokuchanekileyo ngaphambi kokuqhotyoshelweyo ngokusisigxina.

I-Aerospace: Kwishishini le-aerospace, apho ukuchaneka kubaluleke kakhulu, ii-POCVs zisetyenziselwa ukukhusela amacandelo ngexesha lokudibanisa kunye nokuvavanya, ukunciphisa umngcipheko wokungahambi kakuhle.

Ulwakhiwo: Ii-POCVs ziqeshwe kwizixhobo ze-hydraulic kunye nezixhobo, ezibonelela ngokubambelela okuthembekileyo kwizicelo ezahlukeneyo zokwakha.

Ukuqukumbela

Iivalvu zokutshekisha eziqhutywa ngumqhubi wenqwelomoya zizinto eziyimfuneko kwimisebenzi yokubamba i-hydraulic clamping. Ukukwazi kwabo ukubonelela ngokukhuselekileyo, okuthembekileyo, kunye nolawulo olusebenzayo kumacandelo abambeneyo kubenza ukuba bakhethe ukhetho kwizicelo ezahlukeneyo zemizi-mveliso. Njengoko imizi-mveliso iqhubeka nokuvela kwaye ifuna amanqanaba aphezulu okuchaneka kunye nokhuseleko, indima yee-POCVs ngokungathandabuzekiyo iya kubaluleka ngakumbi. Ngokuqonda nokusebenzisa ezi valve ngokufanelekileyo, amashishini anokuphucula ukusebenza kwawo kakuhle, aqinisekise ukhuseleko, kwaye agcine imigangatho ekumgangatho ophezulu kwiinkqubo zawo.
